Find g(-4) if g(x) = 8x^2 + 4x

Answers

Answer:

Your answer would be -144

The value of the function g(x) = 8x² + 4x at g(-4) is 112.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, a function g(x) = 8x² + 4x.

Now to obtain the value of g(-4) we'll simply substitute - 4 in place of x.

which is g(-4) = 8(-4)² + 4(-4).

g(-4) = 8×16 - 16.

g(-4) = 128 - 16.

g(-4) = 112.

Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function B has a greater rate of change. Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function B has a greater rate of

Answers

Answer:

Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of

Step-by-step explanation:

Function A:

[tex]\begin{array}{cccccc}x & {1.5} & {2.5} & {3.5} & {4.5} & {5.5} \ \\ y & {5} & {0} & {-5} & {-10} & {-15} \ \end{array}[/tex]

Function B:

[tex]y = -4.5x + 15[/tex]

Required

Which has a greater rate of change

The rate of change of function A is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where:

[tex](x_1,y_1) = (1.5,5)[/tex]

[tex](x_2,y_2) = (2.5,0)[/tex]

So, we have:

[tex]m = \frac{0-5}{2.5 - 1.5}[/tex]

[tex]m = \frac{-5}{1}[/tex]

[tex]m = -5[/tex]

For function B

The general function is:

[tex]y = mx + b[/tex]

Where

m is the rate of change

By comparing [tex]y = mx + b[/tex] to [tex]y = -4.5x + 15[/tex]

[tex]m = -4.5[/tex]

So, we have that:

Function A has a rate of -5; function B has a rate of -4.5.

By comparison: -4.5 is greater than 5

Hence, function B has a greater rate.

A circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in the square meters.

Answers

The area of the sidewalk is 144.44 m².

The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.

Since the radius is half the diameter, r = 25/2 = 12.5.

The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².

The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.

The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

a person bikes 2 1/2 miles at a constant rate in 1/8 of an hour what distance , does the person bikes in an hour.

Answers

Answer:

20 miles

Step-by-step explanation:

We are given that

Person traveled total distance by bike=2 1/2 miles

Person traveled total distance by bike==[tex]2+\frac{1}{2}=2.5miles[/tex]

Time taken by person ,t=1/8 hour

We have to find the distance traveled by person bike in an hour.

We know that

Rate==[tex]\frac{Distance}{time}[/tex]

Using the formula

Rate=[tex]\frac{2.5}{\frac{1}{8}}[/tex]miles/hr

Rate=20mph

In 1 hour person bike traveled distance=20 miles

Mirela has a rectangular piece of paper with an area of 0.35 m2. She cuts the paper into small rectangles with areas of 700 cm2. What is the maximum number of rectangles she can cut?

Answers

Answer:

The maximum number of rectangles that Mirela can cut is 5

Step-by-step explanation:

First, you must ensure that all the measurements are the same units.

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

where a, b and c are known values and x the value to calculate. So:

[tex]x=\frac{c* b}{a}[/tex]

The direct rule of three is the rule applied in this case where there is a change of units.

To perform this conversion of units, you must first know that 1 m² = 10,000 cm². So, if 10,000 cm² is 1 m², how many cm² equals 0.35 m²?

[tex]cm^{2} =\frac{0.35 m^{2} *10000 cm^{2} }{1 m^{2} }[/tex]

cm²= 3500

Now, to calculate the maximum number of rectangles that Mirela can cut you divide the total area of the paper by the area of each rectangle:

3500 cm² ÷ 700 cm²= 5

The maximum number of rectangles that Mirela can cut is 5
