Evaluate 4 - 0.25 x g + 0.5 x h (g = 10, h = 5)

bearhunter [10]

Step-by-step explanation:

Substitute g = 10, and h = 5 into the expression:

$4 - 0.25(10) + 0.5(5)$

Multiply:

$4 - 2.5 + 2.5$

Cross out -2.5 and 2.5, as they're equal to 0:

If f(x)=1/9x-2, what is f–1(x)?

jekas [21]

we are given

$f(x)=\frac{1}{9x-2}$

For finding inverse function , we do following steps

step-1:

Set f(x)=y

$y=\frac{1}{9x-2}$

step-2:

Switch x and y

$x=\frac{1}{9y-2}$

step-3:

now, we can solve for y

$x=\frac{1}{9y-2}$

Multiply both sides by 9y-2

$x\times (9y-2)=(9y-2)\times \frac{1}{9y-2}$

$x(9y-2)=1$

$9xy-2x=1$

Add both sides by 2x

$9xy-2x+2x=2x+1$

$9xy=2x+1$

now, we can divide both sides by 9x

$y=\frac{2x+1}{9x}$

so, we get inverse function as

$f^{-1}(x)=\frac{2x+1}{9x}$ ................Answer

A car is driving with a constant velocity of 3.00 m/s. After 2.00 minutes, how far has it gone?

dimulka [17.4K]

Answer:

360 m

Step-by-step explanation:

In order to find the distance we need to multiply the time by the velocity.

v=x/t when we solve for x we get v*t=x so,

2 minutes=2*60 sec=120 sec

3*120=360 m
