What is the inverse of the function f(x) = 2x – 10?

1 answer:

4 0

The fourth option is correct. 1. Switch f(x) for y 2. Transfer -10 as a +10 to the left side of the equation. y + 10 = 2x. 3. Then last, divide both sides by 2 to leave the x alone of the right. Now you have x = 1/2y + 5. Now switch back the y and x so it becomes y = 1/2x + 5. Also, make the y an h(x) to finish up.

the area of a square sandbox is 83 square feet. to the nearest foot, what is the perimeter of sandbox?

vagabundo [1.1K]

$Area=bh$
$b=base$
$h=height$

Since a square has 4 equal sides, we can √83 to give us each side. This being $9.11 feet$

$perimeter=9.11+9.11+9.11+9.11=36.44$

$Answer: 36$ to the nearest foot

If 1-cosA = 1/2 , Then find the value of sinA.

zimovet [89]

Step-by-step explanation:

Given :

1- cosA = 1/2

or, CosA = 1 -1/2

Therefore ; CosA = 1/2 = b/h

According to the Pythagoras theorem,

P = root under h^2 - b^2

= root under (2)^2 - (1)^2

= root under 4 -1

= root 3

Again,

SinA = P/h

= root 3 / 2
