Answer:

7.8cos23 feet

Step-by-step explanation:

Which expression can be used to find AC

From the given diagram;

Hypotenuse = AB = 7.8ft

Adjacent to <A = AC

Using the SOH CAH TOA identity;

cos theta = adjacent/hypotenuse

cos 23 = AC/AB

cos 23 = AC/7.8

AC = 7.8cos23

AC = 7.8(0.9205)

Hence the measure of AC is 7.8cos23 feet

Use the table below to fill in missing values.
aliina [53]

Step-by-step explanation:

We can observe from the table that the value of independent variable and then the values of function on that variable are given.

So,

<u>f(5) = 6</u>

As the value of function at x=5 is 6

<u>If f(x) = 4 then x = 7</u>

The value of function is 4 only on x=7 so the answer is x = 7

When the inverse is taken, the inputs become output and the outputs become inputs

f^{-1}(6) = 5

The value of inverse will be 5 because in original function 5 is input and 6 is output when this will be reversed for inverse, the output will be 5 for 6

Now,

Lastly

if\ f^{-1}(x) = 7,\ then \x = 4

The reverse rule of input and output will be used. The reverse function will generate 7 at input 4.

Feliz [49]

Answer:

B) Vertex (1,2), maximum

Step-by-step explanation:

First, determine if the graph has a maximum or a minimum value. Since the graph opens downwards, it has a <u>maximum</u> value.

The maximum is the point that has the greatest y value. We can see that the greatest y value is at y=2. Going down two units from that spot, we can see that the x value is at x=1. We can plug those into the vertex form, (x,y). By plugging in we get the point (1,2).
