In linear equation ,The correct order from least time to greatest time is: Andy, Beth, Cindy.

Describe a linear equation using an example.

An equation with only one variable is referred to as a linear equation in one variable.

                   It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.

Consider the provided information,

Andy walked [tex]2\frac{3}{4}[/tex]  mi at a constant speed of [tex]2\frac{1}{2}[/tex] mi/h.

As we know

       Time = distance/speed

           = [tex]\frac{2\frac{3}{4} }{2\frac{1}{2} }[/tex]

            =  [tex]\frac{11/4}{5/2}[/tex]

           = 11/40

Therefore, Andy takes 1.1 hours.

Beth walked 1 1/2 mi at a constant speed of 1 1/8 mi/h .

  time = [tex]\frac{1 1/2}{ 1 1/8}[/tex]

           = 3/2/ 9/8

           = 4/3

Therefore, Beth takes 1.33 hours.

Cindy walked for 1 h and 24 min at a constant speed of 1[tex]\frac{1}{4}[/tex] mi/h.

   1  hour 24 min   =  1 + 24/60   = 1.4 hours

    Therefore Cindy takes 1.4 hours.

Andy spent least time i.e 1.1 hours and Cindy spent greatest time i.e 1.4 hours.

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 274 people entered the park, and the admission fees collected totaled 836.00 dollars. How many adults were admitted?
a. 209
b.170
c.104

Answers

Therefore in this question the solution of particular equation is  108 children and 175 adults in the amusement park on that particular day.

What is Equation ?

When two expressions' values are set to be equal by a mathematical statement, that statement is known as an equation. To put it another way, it is a mathematical expression that means "this is equivalent to that." An equal sign, a mathematical expression, and a mathematical expression can all be seen on the left side of the symbol. The right ride of the equation frequently contains zero.

Let's first configure our system by giving x and y meaningful definitions. Let x be the total number of kids and y be the total number of adults.

Children cost $1.50, while adults cost $4.00. The number of kids, x, is multiplied by 1.5 to determine how much money a group of kids will cost. The 1.5x symbol stands for this. We will use 4y for adults, who must pay $4 to enter. On the specified day, $862 in total revenue was earned. We must add 1.5x and 4y to get at this sum.

1.5x + 4y = 862 equation required

Second equation: The total number of individuals present on the day is 283. X and Y, or the number of children and adults, must be added together to arrive at this figure.

x + y = 283

System of equations:

1.5x + 4y = 862

x +   y = 283

Thus,

x + y = 283  

y = 283 - x

Substitute y = 283 - x

862=1.5x + 4 (283 - x)  

1.5x + 1132 - 4x = 862

1132 - 2.5x = 862          

-2.5x = -270                  

x = 108

Substitute x =108 back into y = 283 - x

y = 283 - 108 = 175

Therefore there were 108 children and 175 adults in the amusement park on that particular day.

which inequality is less than the quadratic function with zero -7 and 1 and includes the point (2,27/2) on the boundary?

Answers

The second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).

What is a quadratic equation?

The equation of the form ax² + bx +c is known as a quadratic equation.

Given that, the zeros of the quadratic function are -7 and 1 and include the point (2,27/2).

Substitute x = 1 into the given inequality to check whether any of them becomes less than 0 or not:

From the first inequality:

y < -3/2 + 9 + 21/2

y < 18

From the second inequality:

y < 3/2 + 9 -21/2

y < 0

Since the inequality is less than 0, it is also less than the quadratic function at x = 1.

Similarly, checking the third inequality also gives y < 0, but the fourth doesn't.

Now, from the second and the third inequality, check which one is less than 27/2 for x = 2:

From the second inequality:

y < 6 + 18 -21/2

y < 27/2

From the third inequality:

y < -6-9+21/2

y < -27/2

Since the second inequality, y < (3/2)x² + 9x -21/2, is less than 0 at x =1 and less than 27/2 at x=2, it is also less than the quadratic function whose zeros are -7 and 1 and includes the point (2,27/2).

Hence, the second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).

Find the domain and solve 2*4^(sqrt(5x^2-8x)+1)+4=33*2^(sqrt5x^2-8x)

Answers

To find the domain of the expression 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)), we need to consider the values of x for which the expression is defined.

First, we need to consider the square root term, sqrt(5x^2-8x). The square root of a number is only defined for nonnegative values, so we need to find the values of x for which 5x^2-8x is nonnegative. We can do this by setting 5x^2-8x equal to 0 and solving for x:

5x^2-8x=0

5x(x-8)=0

We can see that x=0 and x=8 are the solutions to this equation. Since the square root of a negative number is not defined, the expression 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)) is only defined for x values that are greater than or equal to 0 and less than or equal to 8. This means that the domain of the expression is x ∈ [0, 8].

To solve the equation 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)), we can start by isolating one of the exponential terms on one side of the equation. Let's isolate the term 2^(sqrt(5x^2-8x)):

24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x))

22^(2sqrt(5x^2-8x)+1)=332^(sqrt(5x^2-8x))

2^(2sqrt(5x^2-8x)+1)=16.52^(sqrt(5x^2-8x))

2sqrt(5x^2-8x)+1=4.5+sqrt(5x^2-8x)

sqrt(5x^2-8x)=3.5

5x^2-8x=12.25

5x^2-8x-12.25=0

We can use the quadratic formula to solve this equation for x:

x = (-(-8) ± sqrt((-8)^2 - 45(-12.25))) / (2*5)

x = (8 ± sqrt(64 + 97)) / 10

x = (8 ± sqrt(161)) / 10

x = (8 ± sqrt(289)) / 10

x = (8 ± 17) / 10

x = -9/10 or 25/10

Since x must be greater than or equal to 0 and less than or equal to 8, the only solution that is within the domain of the expression is x=25/10, or x=2.5.

Therefore, the solution to the equation 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)) is x=2.5.

what do you mean by domain of a function?

The domain of a function is the set of all input values for which the function is defined. In other words, it is the set of all values that can be plugged into the function as an argument, or input, and produce a valid output

For example, consider the function f(x) = x^2. The domain of this function is all real numbers, since the function is defined for any value of x. However, some functions may not be defined for certain values of x. For example, the function g(x) = 1/x is not defined for x=0 because division by zero is not allowed. In this case, the domain of the function g(x) would be all real numbers except for x=0.

One of the interior angles of the triangle, angle y is equal to 67° and the exterior angle x is equal to 113°.

Sum of interior angles of a triangle.

The interior angles of a triangle have a total sum of 180°.

Considering the triangle with interior angles: y, 51°, and 62° we have that;

y + 51° + 62° = 180°

y + 113° = 180°

y + 113° - 113° = 180° - 113° {subtract 113° from both sides}

y = 67°

the exterior angle x and the angle y lie on a straight line, so they sum up to 180°.

x + 67° = 180°

x + 67° - 67° = 180° - 67° {subtract 67° from both sides}

x = 113°

Therefore, the interior angle y = 67° and the exterior angle x = 113°.

When double derivative becomes zero, the graph of the function is neither increasing nor decreasing and hence, the the function attains either

a maxima or a minima.

Hence, he global maximum value of a differentiable function f(x) on a closed interval [a, b] must occur at a critical value or an endpoint.

The minimum amount required by a bank to open a new checking account is $75. Write an inequality that represents the amounts in dollars a that could be used to open a new account. ​

Answers

The Inequality expression that shows the above situation is x ≥ 75.

What is inequality:      

The word "inequality" describes the state of being unequal, In Inequalities like in equations, we compare two values but not with the equal signs here we use signs like Not equal, less than, less than or equal to; greater than or greater than or equal to, etc.

             

Here we have,

The minimum amount required to open a new checking account is $ 75        

Let us assume that we used $ x dollars to open a bank account

By the given data,

The amount is a minimum of $ 75  

=> x ≥ 75      [ x is less than or equal to $ 75 ]

Therefore,

The Inequality expression that shows the above situation is x ≥ 75.

a) The percentage reduction in the price of the television each time is as follows:

First time = 10.42%Second time = 11.63%.

b) The absolute change after the two reductions amounting to $100 is that the price of the television is now $380.

c) The overall percentage decrease in the price of the television is 20.83%.

What is the percentage?

The percentage is the ratio.

The percentage is computed as the quotient of the smaller value (numerator) over the larger value (denominator), between two values.

Percentages are depicted using the percentage sign (%) to show that the value is expressed over 100.

Price of the television = $480

First price reduction = $50

New price after the first price reduction = $430 ($480 - $50)

Percentage reduction in price = 10.42% ($50/$480 x 100)

Second price reduction = $50

New price after the second price reduction = $380 ($430 - $50)

Percentage reduction in price = 11.63% ($50/$430 x 100)

Overall percentage decrease = 20.83% ($100/$480 x 100)

Thus, overall, the price of this television decreased by 20.83 percent.

a) The velocity of the particle is described by v(t) = - 3 · t² + 12 · t - 9.

b) The particle is at rest when t = 1 s. and t = 3 s.

c) The particle changes its direction when t = 1 s. and t = 3 s.

d) The particle is moving right when 0 s < t < 1 s and t > 3 s and left when 1 s < t < 3 s.

e) The acceleration of the particle is described by a(t) = a(t) = - 6 · t + 12.

f) The velocity increases at t = 1 s.

g) The particle has a total distance of 54 meters.

How to analyze the kinematics of a particle

In the statement we find the function of a particle that describes its position (y), measured in meters, in time (t), in seconds. Herein we shall analyze the function to determine all important features.

a) The velocity of the particle (v), in meters per second, is the first derivative of the function position:

v(t) = - 3 · t² + 12 · t - 9

b) The particle is at rest when v(t) = 0. Now we proceed to determine the roots of the resulting polynomial:

- 3 · t² + 12 · t - 9 = 0

t = 3 s. or t = 1 s.

c) The particle changes its direction when v(t) = 0. Then, this change happens in t = 1 s and t = 3 s.

d) The particle is moving right when v(t) > 0, then:

(t - 1) · (t - 3) > 0

There are two possible intervals: (i) 0 s < t < 1 s, (ii) t > 3 s. The particle is moving left when 1 s < t < 3 s.

e) The acceleration is the second derivative of function position, thus:

a(t) = - 6 · t + 12

f) The velocity increases when a(t) > 0. Then, the acceleration at t = 1 s is:

a(1) = - 6 · 1 + 12

a(1) = 6

The velocity is increasing at t = 1 s.

g) The total distance (s), in meters, traveled is determined by the following expression:

s = |x(1) - x(0)| + |x(3) - x(1)| + |x(6) - x(3)|

s = |7 - 11| + |11 - 7| + |- 43 - 11|

s = |- 4| + |4| + |- 54|

s = 54

Exercise promotes healthy bones, muscles, and joints. It also reduces peoples risk for obesity and many diseases. Nevertheless, to cut budgets and devote more time to academics, schools across the United States have reduced, or even eliminated, physical education classes. A 2006 study reported that only 14 percent of elementary schools, 15 percent of middle schools, and 3 percent of high schools in the United States offered the equivalent of three class periods of physical education per week. In addition, many elementary schools have eliminated recess. And outside of school, many students lead a sedentary lifestyle. Given these facts, has the reduction of physical education in schools been a wise decision?Several recent scientific studies have found that exercise has a benefit not previously realized: It improves childrens brain function. One study took place at the Champaign-Urbana campus of the University of Illinois. There, researchers had nine- and ten-year-olds run on a treadmill to determine their fitness levels. Previous studies with animals had shown that baby rodents that had access to running wheels enlarged certain areas of their brains. They also performed better on rodent intelligence tests than did less active baby rodents. The study of nine- and ten-year-olds yielded similar results. First, the children were asked to respond to arrows on a computer screen. The fit children were better at paying attention to relevant cues and ignoring unnecessary information. Then magnetic resonance imaging (MRI) technology was used to scan the childrens brains and measure specific areas. The MRIs showed that the fit children had significantly larger basal ganglia. (This part of the brain helps to maintain attention and coordinate thoughts and actions.) The children in the fit and unfit groups had similar socioeconomic backgrounds, body mass index, and other variables. Therefore, researchers concluded that physical fitness was responsible for the enlargement of the basal ganglia.In a second study, also at the University of Illinois, a different group of nine- and ten-year-olds was also categorized according to fitness levels. These children were given tests of their complex memory. This activity takes place in the part of the brain called the hippocampus. MRI scans showed that the fit children had a heavier hippocampus than did the children who were less fit. The basal ganglia and the hippocampus interact in many brain functions needed for intricate thinking. Researchers concluded that if exercise strengthens the size of these regions and strengthens the connection between them, being fit might contribute to better thinking.Even a small amount of aerobic activity can have a positive impact. An earlier study at the University of Illinois found that just twenty minutes of walking before a test raised childrens test scores. This result occurred even if the children were overweight or otherwise unfit.Question1. Which sentence best expresses the main idea of the passage?a. Exercise is important for good health.b.
