The function below shows the number of car owners f(t), in thousands, in a city in different years t:

stepladder [879]

Answer:

6.3

Step-by-step explanation:

<u>The number of car owners f(t) </u><u>in year 5</u><u> is found by plugging in 5 into t of the equation:</u>

$f(5)=1.1(5)^{2}-2.5(5)+1.5=16.5$

<u>The number of car owners f(t) </u><u>in year 3</u><u> is found by plugging in 3 into t of the equation:</u>

$f(3)=1.1(3)^{2}-2.5(3)+1.5=3.9$

So there is a change of $16.5-3.9=12.6$ in the 2 years. So to get per year, we divide 12.6 by 2, to get:

$\frac{12.6}{2}=6.3$

Hence, <em>"The average rate of change of f(t) from t = 3 to t = 5 is </em><em>6.3 </em><em>thousand owners per year."</em>

The perimeter of a rectangle is 64m and it’s length is 3 times it’s width.what is the length of the rectangle?

Verdich [7]

so umm this is the answer

Perimeter = 2(length + width)

P = 2(L+w)

We are told the length is 3 times the width...

L = 3w

64 = 2(3w + w)

64 = 2(4w)

64 = 8w

8 = w

L = 3w = 3(8) = 24 cm

Length is 24 cm

width is 8 cm

Hüseyin draws a fox with a scale of 3 units on his graph paper represents 15cm. The fox has an actual height of 80cm. What is th

Over [174]

Answer:

The height of the fox in Huseyin's drawing is, 16 units

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the statement: Huseyin draws a fox with a scale of 3 units on his graph paper represents 15 cm. The fox has an actual height of 80 cm.

⇒ We are given Scale of 3 units.

On graph paper the length of fox is 15 cm.

The fox has an actual height = 80 cm

let x be the height in units of the fox in Huseyin's drawing.

By definition of proportion;

$\frac{3}{15} = \frac{x}{80}$

by cross multiply we get;

$3 \times 80 = 15x$

Simplify:

240 = 15x

Divide both sides by 15 we get;

x = 16 units.

Therefore, the height of the fox in Huseyin's drawing is, 16 units
