Answer:

Step-by-step explanation:

To solve, first plug in 4 as your x value for your g(x) equation.

$g(4)=\sqrt{4-3} \\g(4)=\sqrt{1} \\g(4)=1$

Next, plug in the value of g(4) into your f(x) equation for x.

$f(1)=-1+7\\f(1)=6$

In the triangle below,<br> y = [ ? ] cm. Round to the<br> nearest tenth.

sattari [20]

Answer:

The answer is

Step-by-step explanation:

Since the triangle is a right angled triangle we can use trigonometric ratios to find y

To find y we use cosine

cos∅ = adjacent / hypotenuse

From the question

y is the adjacent

The hypotenuse is 15

So we have

$\cos(35) = \frac{y}{15} \\ y = 15 \cos( 35 ) \\ y = 12.28728$

We have the final answer as

<h3>12.3 cm to the nearest tenth</h3>

Hope this helps you
