Let f be defined as shown on the graph. Which statement is true?

1 answer:

4 0

The inverse of f does NOT exist. The reason why is because the function fails the horizontal line test. Recall that the horizontal line test is a test where you try to see if you can pass a single horizontal line through more than one point on the function curve. If you can get the horizontal line to pass through more than one point, then it fails the test. It's very similar to the vertical line test.

givi [52]

Answer:

2.5477 feet

Step-by-step explanation:

Refer the image attached to understand my solution.

BC = height of lamppost.

DE = Julia

AD = shadow of Julia

BD = 2 feet. AD = 5 feet

BA = BD + AD

= 2 + 5 = 7 feet

In ΔABC

tan 20° = $\frac{BC}{BA} = \frac{BC}{7}$

BC = 7 * tan 20°

BC = 2.5477 feet

SO the height of lamppost = 2.5477 feet

Answer:

Step-by-step explanation:

Note that if there are two of the same number multiplied within a root, it becomes a whole number

√18 x √18 = 18

Next, simplify √4. Factor the number:

√4 = √(2 x 2) = 2

Multiply: 18 x 2 = 36
