Answer:

f(x) = y

y = 7.50x

To find the inverse, swap x and y

x = 7.50y

Now solve for y

y = x/7.50

f-1(x) = x/7.50

If f(x)= x2 + 1 and g(x) = 3x + 1, find 2f(1) + 3g(4) •45 •43 •42

Alex73 [517]

Answer:

the answer is 43.

Step-by-step explanation:

We have functions

$f(x) = x^2+1$

$g(x)=3x+1,$

and we want to evaluate

$2f(1) + 3g(4)$

For this we first evaluate $f(1)$ and $g(4)$ separately:

$f(1)=(1)^2+1=2$

$g(4)=3(4)+1=13$

Therefore

$2f(1) + 3g(4)= 2(2)+3(13)=43$

So we have

$\boxed{2f(1) + 3g(4)=43}$

The chairlift at a ski resort rises a total of 2600 feet from where it starts. The angle of elevation is about 22.3 degrees. How

Monica [59]

Answer:

6852 feet .

Step-by-step explanation:

Refer the attached figure

The chairlift at a ski resort rises a total of 2600 feet from where it starts. i.e.AB = 2600 feet

The angle of elevation is about 22.3 degrees.i.e.∠ACB= 22.3°

We are supposed to find How far do riders travel on the lift i.e.AC

In ΔABC

We will use trigonometric ratio

$Sin\theta =\frac{Perpendicular}{Hypotenuse}$

$Sin22.3^{\circ} =\frac{AB}{AC}$

$AC=\frac{2600}{Sin22.3^{\circ}}$

$AC=\frac{2600}{0.379456159529}$

$AC=6851.9$

So, riders travel 6852 feet .
