Answer:

-12.5 -10.5n

Step-by-step explanation:

Use distributive property to solve:

1. -2.5 x -3 = 7.5

2. -2.5 x 4.2n = -10.5n

3. -2.5 x 8 = -20

Simplify:

7.5-20= -12.5

-12.5 -10.5n

By using the functions we have found the value of x and it is found out to be as x = -20/3.

What is a function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

Given data:

f(x) = -4x + 1, g(x) = x2 - 8x + 21, and h(x) = 19 - 3x and h(x) = 39.

By using the h(x) function, we can write

               h(x) = 19 - 3x

                39 = 19 - 3x

                3x = 19 - 39

                3x = -20

                  x = -20/3

Hence, by using the functions we have found the value of x and it is found out to be as x = -20/3.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The vertex = (- 4, - 8)

And, The focal diameter = 16

Now,

Since, The vertex (h, k) = (- 4, - 8)

And, The focal diameter (4a) = 16

⇒ 4a = 16

⇒ a = 4

Hence, The equation of parabola with vertex (h, k) will be;

⇒ y = a (x - h)² + k

Substitute all the values, we get;

⇒ y = 4 (x - (-4))² + (-8)

⇒ y = 4 ( x + 4)² - 8

Thus, The equation of parabola will be;

Explanation

The height of the ball as a function of the time is given by the following formula:

A. Maximum height of the ball

To find the value of the maximum height, we maximum the function h(t) computing its first derivative and equalling the result to zero:

Solving the last equation for t, we get time t when the height is maximum:

So the maximum height is given by the value of h(t) when t = 2.5:

The maximum height is 196ft.

B. Time until the ball hits the ground

The ball will hit the ground when h(t) = 0. So we must find the value of t such that:

Solving this equation is equivalent to finding the roots of a second-order polynomial:

Where:

• a = -16,

,

• b = 80,

,

• c = 96.

The roots of this polynomial are given by the following formula:

In linear equation, 3 t is the maximum possible weight .

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Assuming x to be lightest , y median and z the heaviest.

So according to given information average is 7 so total sum for three box = 21

thus x+y+z = 21

Given y=9 (median weight)

thus x+z = 12

For maximum possible value for x is 3 such that z= 9

if x=4 then Z= 8(this changes median to 8)

So maximum possible value for lightest box is 3

The slopes of the segments can be the same as long as the change in y divided by the change in x of both segments is the same. This means that the two segments are parallel.

The slope of a linear function represents the rate of change of the output variable y relative to the input variable x.

Hence, given two points on a line, the slope is calculated by the division of the change in y divided by the change in x.

As long as the changes are the same, two different segments can have the same slope, which is the case when they are parallel, meaning that they meet only at infinity.

One possible example of two parallel segments is given as follows:

The solutions are that Two comparable triangles have proportional corresponding sides. And Two comparable triangles matching angles

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

For a regular polygon of any number of sides, therefore the sum of its exterior angle is 360°.

Given statements that the corresponding sides might be altered, they must still be proportionate.

The triangles will be congruent also, if they are.

But the angles must always line up otherwise the triangle's overall shape will change and it won't look the same.

Two comparable triangles must have proportional corresponding sides.

Chord AC is the nearest to the center because the perpendicular distance of chord AC from center O is the smallest.

What is a chord of a circle?

A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. The infinite line extension of a chord is a secant line or just secant. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse.

ΔABC is inscribed in O. If AB = 5, BC = 8, and AC =9.

Now if you look carefully at the given diagram, we can see that the perpendicular distance of chord AC from center O will be smaller than the perpendicular distance of chord AB from center O and the perpendicular distance of chord BC from center O.

The expected value is μ = p

Then the standard error will be

The formula to find the common difference of an arithmetic sequence is: d = a(n) - a(n - 1), where a(n) is a term in the sequence, and a(n - 1) is its previous term in the sequence

What is arithmetic sequence?

A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. For instance, the number sequence 5, 7, 9, 11, 13, and 15 has a common difference of 2 in arithmetic.

Sequences can in fact begin at any number that we choose. A sequence with the general word an is commonly notated as ann=1 a n n = 1.

or d = (an + 1 - an) (an – an-1). AP reduces if the common difference is negative. For instance, the AP drops in these numbers: -4, -6, -8.

Denise puts $67.50 in the savings account every week.

What is a percentage?

Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.

To find out how much money Denise puts in the savings account each week, you need to multiply her weekly earnings by the percentage she puts into the savings account.

First, convert the percentage to a decimal by dividing by 100: 30% = 0.30

Then, multiply Denise's weekly earnings by this decimal to find the amount she puts into the savings account each week:

=$225 * 0.30

=67.50.

What is compound interest?

Compound interest is the interest imposed on a loan or deposit amount. It is the most commonly used concept in our daily existence. The compound interest for an amount depends on both Principal and interest gained over periods.

Given, Principal = $9,000

Interest = 12% = 0.12

For compounded monthly, n = 12

The compound amount for monthly compounded is given by

[tex]A = P(1 + \frac{r}{n} )^{nt}[/tex]

or, A = [tex]9000(1 + \frac{0.12}{12} )^{12*4}[/tex]
