Select the correct answer. Which situation is best modeled by a linear function with time as the independent variable?

A. the distance traveled by a car driving at a constant 40 miles per hour

B. the value of a car that decreases by 15% each year

C. the total population of a bacteria sample that is doubling in size every 2 days

D. the height of a ball that has been thrown into the air and falls back to the ground​

Answer:

Step-by-step explanation:

y = x^2 + 8x + 15

= x^2 + 8x + 4^2 - 4^2 + 15

= (x+4)^2-1

Answer:

(−4, −1)

vertex, axis of symmetry, and y-intercept: y = (x + 4)² −1

The answer is put x=2

Y=2

Answer:

x = 2

Step-by-step explanation:

The parallel lines divide the transversals into proportional segments, that is

[tex]\frac{x+4}{13.5}[/tex] = [tex]\frac{4}{9}[/tex] ( cross- multiply )

9(x + 4) = 54 ( divide both sides by 9 )

x + 4 = 6 ( subtract 4 from both sides )

x = 2

Answer:

Step-by-step explanation:

The function C has the greatest initial value, and the function B has the greatest rate of change

A linear function is a function whose value changes at a constant rate.

A linear function is represented as:

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

Where

The initial value of function A is 0.

This is so because y = 0, when x = 0

The initial value of function B is -1

This is so because the value of function y = 3x - 1 is -1, when x = 0

From the graph, the initial value of function C is 2

Hence, the function C has the greatest initial value

Rate of change is calculated as:

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

So, the rate of change of function A is calculated as follows:

[tex]m = \frac{5 - 0}{2-0}[/tex]

[tex]m = \frac{5 }{2}[/tex]

[tex]m = 2.5[/tex]

The rate of change of function A is 2.5

The rate of change of function B is 3.

The rate of change of function C is calculated as follows:

[tex]m = \frac{3 - 2}{3-0}[/tex]

[tex]m = \frac{1}{3}[/tex]

The rate of change of function C is 1/3

Hence, the function B has the greatest rate of change

Answer:

[tex]\frac{45}{100}\\\\ \frac{9}{10}[/tex]

[tex]\frac{10}{100} = 10%[/tex]

Step-by-step explanation:

125 % can be expressed as decimal as

[tex]\frac{125}{100} \\\frac{25}{20} \\\frac{5}{4}[/tex]

Rule in changing Percent to decimal

a) Divide a percent by 100

b) Remove percent sign

example

30%

= 3/10

45 %

[tex]\frac{45}{100}\\\\ \frac{9}{10}[/tex]

[tex]\frac{10}{100} = 10%[/tex]

Hi there!

So what we need to do here is this...

Multiply -3/4  with there own parentheses and multiply 2 with it’s own parentthese also.

[tex]- \frac{3}{4} x 5p = 3 \frac{3}{4} p[/tex]

[tex]-\frac{3}{4} x 12 = 9[/tex]

Then do the second parenthese...

[tex]2x8=16[/tex]

[tex]2x - \frac{1}{4} = \frac{1}{2}p[/tex]

Add them like this...

[tex]( 3 \frac{3}{4}p + 9 ) + ( 16 -\frac{1}{2}p )[/tex]

Simplflied it again.../ since 3 3/4 and 1/2 both have p, add them...

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

Add the rest:

[tex]3 \frac{1}{4}p+9+16[/tex]

Answer:

Measure of angle s:

Sum all angles of triangle is = 180 degrees

So,

31 + 58 + x = 180

x = 180 - 31 - 58

x  = 91

Measure of angle s: 91 degrees

ST = 17.005

RT = 33.012

Answer:

34 ounces

Step-by-step explanation:

Here is the full question

Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle?

Let b = total ounces in the bottle

the equation that can be derived from this question is :

0.2 x b = 6.8

To find b, divide both sides by 0.2

b = 6.8 / 0.2 = 34 ounces

Answer:

The answer is "[tex]22^{\circ}[/tex]"

Step-by-step explanation:

Please find the question image file in the attachment:

In this question, [tex]\angle B =90^{\circ}[/tex], that is made up of the two complementary angles that are 57 and 3x.

So, the equation is:

[tex]\to 57+3x=90\\\\\to 3x=90-57\\\\\to 3x= 33\\\\\to x=\frac{33}{3}\\\\\to x= 11[/tex]

In [tex]\Delta ABC[/tex]:

BC=2x

put the value of x in above then [tex]BC= 2\times 11^{\circ} =22^{\circ}[/tex]
