The function h is defined by h (y) = 2y-7.<br> What is the value of h(8) ?<br> ooo

kozerog [31]

Answer:

The value of h(8) = 9

Step-by-step explanation:

Given function as

h(y) = 2y - 7

For y = 8

Put the value of y in given function

So, h(8) = 2 (8) - 7

OR , h(8) = 16 - 7

∴ h(8) = 9

Hence the value of h(8) = 9 Answer

The equation tan(55) = 15/b can be used to find the length of line AC.what is the length of line AC round to the nearest 10th 3.

Nadusha1986 [10]

Answer:

10.5 in

Step-by-step explanation:

Given

$tan(55) = \frac{15}{b}$

Required

Find length AC

The question is not detailed enough; so, I'll assume that b represents line AC.

Having said that;

We start by multiplying both sides by b

$tan(55) = \frac{15}{b}$

$b * tan(55) = \frac{15}{b} * b$

$b * tan(55) =15$

Divide both sides by tan(55)

$\frac{b * tan(55)}{tan(55)} = \frac{15}{tan(55)}$

$b = \frac{15}{tan(55)}$

Find tan(55)

$b = \frac{15}{1.42814800674}$

$b = 10.5031130731$

$b = 10.5$ <em>(Approximated)</em>

<em />

Length AC is 10.5
