Answer:

If in 2020, registration was $285.The  percentage that the summer camp registration decrease in 2021 is 5.26%%.

Using this formula to find the decrease in percentage

Decrease in percentage = [2020 registration cost -  (2020 registration cost - 2020 summer registration)] / 2020 registration cost

Let plug in the formula

Decrease in percentage = [285 - (285 -15)] /285

Decrease in percentage =285 - 270 / 285

Decrease in percentage = 15 /285

Decrease in percentage =0.0526× 100

Decrease in percentage =5.26%

Therefore 5.26% is the decrease in percentage .

Answer:

x=5, y=1

Step-by-step explanation:

you subtract  to get rid of 'y' in the equation like you are subtracting two numbers

7x+4y=39

2x +4y =14

5x=25

simplify to get 'x'

x=5

to get 'y' substitute the value of 'x' in one of the equations

2x+4y=14

(2x5)+4y=14

10+4y=14

subtract 10 to get 'y' on its own

4y= 4

simplify to get 'y'

y= 1

The inverse of the function is 3+[tex]\sqrt[3]{x\x-2}[/tex].

What is inverse of the function?

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1. One should not confuse (-1) with exponent or reciprocal here.

Given, f(x) = (x − 3)³ + 2

replace f(x) with y

y = (x − 3)³ + 2

y-2 = (x − 3)³

∛y-2 = x-3

∛y-2 +3 = x

Put y =x

we get

∛x-2 +3 =y

The dimension(width and length) of the rectangle are 14 meters and 19 meters respectively.

A rectangle is a quadrilateral that has opposite sides equal to each other. The opposite sides are parallel to each other.

Therefore, the rectangles length is 5 meters more than its width. The  perimeter is 66 meters.

Hence,

perimeter of a rectangle = 2(l + w)

where

Therefore,

l = 5 + w

Hence,

66 =  2(5 + w + w)

66 = 2(5 + 2w)

66 = 10 + 4w

66 - 10 = 4w

56 = 4w

Answer:

The number is 11.

Step-by-step explanation:

Step one: Convert to algebraic equation

4 x ( a -6 ) = 20

Step two: Simplify both sides of the equation.

4 (a −6) = 20

(4)(a) +(4)(−6) = 20 (Distribute)

4a +−24 = 20

4a −24 = 20

Step three: Add 24 to both sides.

4a −24 +24 = 20 +24

4a = 44

Step four: Divide both sides by 4.

(4a /4) = (44 /4)

a = 11

Answer:

  9 cm

Step-by-step explanation:

Given two beetles on a roof with a first face having a slope of -2/3 and the second face perpendicular to it. The first beetle travels down the first face twice as fast as the second beetle travels down the second face. You want to know their vertical separation when their horizontal separation is 72 cm.

In a given unit of time, the first beetle will travel 2×3 = 6 cm horizontally, and 2×(-2) = -4 cm vertically. The second beetle will travel 2 cm horizontally and -3 cm vertically in the same time, a perpendicular distance half as far.

After that one unit of time, the separation between the beetles is ...

  horizontally: 6 +2 = 8 cm

  vertically: -3 -(-4) = 1 cm

We notice the vertical separation is (1 cm)/(8 cm) = 1/8 of the horizontal separation. When the horizontal separation is 72 cm, the vertical separation will be ...

  (1/8)(72 cm) = 9 cm

The second beetle is 9 cm above the first when their horizontal separation is 72 cm.

__

Additional comment

The rise/run for the first face is given as (-2 cm)/(3 cm) = -2/3. The second face is perpendicular, so will have a rise/run = -1/(-2/3) = 3/2. That is, for a run of -2 cm, the rise will be -3 cm.

We note that the right triangles with legs "rise" and "run" are congruent for the two beetles. Traveling at the same speed, each beetle will cover a hypotenuse length in a given unit of time, hence the lengths "rise" and "run" on their respective roof faces. Since beetle 1 travels twice as fast, its distance will be 2·rise and 2·run in each time unit.

The attached diagram shows the geometry of the problem. The measures show beetle 1 has traveled twice as far as beetle 2 when they are separated horizontally by 72 cm. The grid is set so you can see the slopes are -2/3 and 3/2.

The domain for plotting the growth function will be [0, 5].

A function's domain is the set of its possible inputs or the set of input values for which the function is defined. The domain is the set of objects that the machine will accept as inputs in the function machine metaphor.

If the f(n) = 11.04 cm

By substituting the value in the equation,

11.04 = 10(1.02)n

(1.02)n = 11.04/10

(1.02)n = 1.104

Take log on both the sides,

log(1.02)n = log(1.104)

n[log(1.02)] = log(1.104)

n = 4.996 ≈ 5 years

What is rational and irrational number?

 Perfect squares like 4, 9, 16, 25, and other integers are included in the category of rational numbers. Surds like 2, 3, 5, 7, and so forth are examples of irrational numbers. Rational numbers have whole integers for both their numerator and their denominator, meaning that their denominator is not equal to zero. All whole numbers, fractions, and decimal numbers that finish or repeat are considered rational numbers. Any number that is not rational—that is, any number that cannot be divided by a fraction—is considered to be irrational.

The number of home runs hit by player A nd player B are respectively 53 and 55which are consecutive odd integers.

Let the number of home runs hit by A is x.

Therefore the number of home runs hit by B is x+2 as they are consecutive odd numbers.

If x is odd then x + 1 is even and x+2 is odd.

The sum of their home runs is 108.

We will form a linear equation in x to represent this situation.

x + (x+2) = 108

now we will solve this equation to find the value of x.

or, 2x + 2 = 108

or, x + 1 = 54

or, x = 53

Hence the number of home runs hit by A is 53 .

Number of home runs hit by B = 53+2 = 55

Therefore the number of homeruns hit by players A and B are 53 and

The ordered pair that shows the dilation of the square ABCD, located at A(-10, -2), B(-5, -2), C(-5, -7), and D(-10, -7), by a scale factor of 5 about the origin is option B

B. A'(-50, -10), B'(-25, -10), C'(-25, -35), and D'(-50, -35)

A dilation transformation is in which the sizes of the sides of the pre image or original figure is changes proportionately to get the image.

The vertex of the preimage ABCD are; A(-10, -2), B(-5, -2), C(-5, -7), and D(-10, -7)

A dilation by a scale factor of 5 is found using the formula;

(x, y) Dilation by scale factor of 5 about the origin ⇒ (5·x, 5·y)

Therefore, the coordinates of the square ABCD following a dilation by a scale factor of 5 is therefore;

A'(5 × -10, 5 × -2), B'(5 × -5, 5 × -2), C'(5 × -5, 5 × -7), and D'(5 × -10, 5 × -7)

Which gives;

A'(-50, -10), B'(-25, -10), C'(-25, -35), and D'(-50, -35)

Checking the lengths of the sides gives;

AB = 5

A'B' = -25 - (-50) = 25

BC = 5

B'C' = -10 - (-30) = 25

CD = 5

C'D' = -25 - (-50) = 25

AD = 5

A'D' = -10 - (-35) = 25

Therefore, the lengths of the sides of A'B'C'D' are 5 times the lengths of the sides of the square ABCD

The correct option is therefore option B

The probability that only one of the counters is white is the fraction 6/11 or 0.55 considering that the first take is without replacement

The probability for an event without replacement implies that once an item is taken, then we do not replace it back to the sample space before taking a second item.

Given that there are 11 counters in the bag, with 5 of them being white;

The probability of taking a white counter = 5/11

The probability of not taking a white counter = 6/11

The probability of taking a white counter first without replacement and not taking it the second time = (6/11) × (5/10)

The probability of not taking a white counter first without replacement and taking it the second time = (5/11) × (6/10)

The probability that only one of the counters is white = (6/11) × (5/10) + (5/11) × (6/10)

The probability that only one of the counters is white = (30/110) + (30/110)
