Answer:

» Answer: The third objective

${ \tt{h(x) = - 4x + 1}}$

• make x the subject:

${ \tt{h(x) - 1 = - 4x }} \\ \\ { \tt{x = \frac{h(x)}{ - 4} - \frac{1}{ - 4} }} \\ \\ { \tt{x = - \frac{h(x)}{4} + \frac{1}{4} }}$

• Therefore, f(x):

${ \boxed{ \boxed{ \tt{ \: \: f(x) = - \frac{1}{4}x + \frac{1}{4} \: \: }}}}$

Calculate the area of each circle

Triss [41]

Answer:

1.54 in²

Step-by-step explanation:

Given that,

→ Radius (r) = 0.7 in

Formula we use,

→ πr²

The area of the circle will be,

→ πr²

→ (22/7) × 0.7 × 0.7

→ (22/7) × 0.49

→ [ 1.54 in² ]

Hence, area of circle is 1.54 in².

In the table below, y varies inversely as x. What is the missing value?

Minchanka [31]

Answer:

<h2>The value of y is 0.5, so the answer is C.</h2>

Step-by-step explanation:

Find first the constant of variation.

Given: x = 3, y = 4

Find: k = ?

Formula:

$y = \frac{k}{x}$

Solution:

$y = \frac{k}{x} \\ 4 = \frac{k}{3} \\ 12 = k$

Then, find the value of y in the third box.

Given: x = 24, k = 12

Find: y = ?

Formula:

$y = \frac{k}{x}$

Solution:

$y = \frac{k}{x} \\ y = \frac{12}{24} \\ y = \frac{1}{2} \\\boxed{y = 0.5}$

A car with a cost price of $5200 is sold at a profit of 15%. Calculate the selling price

andriy [413]

Answer:

We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price. This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15

$Sold\ Price = Initial\ Price *(Total\ Percentage+Profit\ Percentage)$

$Sold\ Price = \$5200*(1+0.15)$

$Sold\ Price = \$5200*(1.15)$

$Sold\ Price = \$5980$

Therefore, our final answer is that the selling price was $5980

If R is the midpoint of PS with PR = 7x + 23 and RS= 13x-19 then find PS

Rainbow [258]

If R is the midpoint of PS, then PR = RS -- (1)

Also, PR + RS = PS -- (2)

__________________

PR + RS = PS

7x + 23 + 13x - 19 = PS

__________________

Now, PR = PS

7x + 23 = 13x - 19

7x - 13x = -19 - 23

-6x = -42

x = -42/-6

x = 7

__________________

PS = 7x + 23 + 13x - 19

PS = 7(7) + 23 + 13(7) - 19

PS = 49 + 23 + 91 - 19

PS = 144 

Hope it helps!
