Given:

The values in the table represent a function.

x f(x)

-2 1

1 3

4 -2

-3 0

0 4

To find:

Function notation for the ordered pair given in the first row in the table.

Solution:

We know that, if a point (a,b) is on the function, then $f(a)=b$ .

From the given table, the ordered pair given in the first row is (-2,1). So,

$f(-2)=1$

Therefore, $f(x)=1$ when $x$ is $-2$ .

AB Round your answer to the nearest hundredth. С 4 A 25° ? B

Nana76 [90]

Answer:

AB ≈ 4.41

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos25° = $\frac{adjacent}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{4}{AB}$ ( multiply both sides by AB )

AB × cos25° = 4 ( divide both sides by cos25° )

AB = $\frac{4}{cos25}$ ≈ 4.41 ( to the nearest hundredth )

What is 6 1/2% of 580

Rudik [331]

1/2 can also be written as 0.5, so you're asking what 6.5% of 580 is. To get 1% you divide by 100 which is 5.8. You can then multiply 5.8 by 6 to get 34.8 (6%). To get 0.5%, you halve 5.8 to get 2.9. Then, you add 2.9 and 34.8 which is 37.7, and that should be your answer! Hope this helped!
