Find f`(x) for the following function. Then find f(5),f(0),f(-9). f(x)=2x+1 (simplify)

1 answer:

4 0

If f`(x) means the derivative, or gradient, of f, then the answer is 2.
f(5)=11, f(0)=1 and f(-9)=-17.
We can calculate the gradient using these values:

Gradient=(11-1)/(5-0)=(-17-1)/(-9-0)=(-17-11)/(-9-5)=2.

Answer:

1.63 cm (across the centerline from release)

Step-by-step explanation:

If we assume time starts counting when we release the weight from its fully-extended downward position, then the position at 1.15 seconds can be found from ...

h(t) = -7cos(2πt/4)

h(1.15) = -7cos(π·1.15/2) = -7(-0.233445) ≈ 1.63412 . . . cm

That is, 1.15 seconds after the weight is released from below the resting position, it will be 1.63 cm above the resting position.

If it is released from above the resting position, it will be 1.63 cm below the resting position at t=1.15 seconds.

7,220 kids drink zero.

14,060 kids drink one

5,700 kids drink two

(multiply the total amount of kids by the percent (convert percent to decimal))

When added together, you get 26,980.

24. C

5,700 kids drink two

2,660 kids drink three

1,140 kids drink four

7,220 kids drink five or more

When added together, you get 16,720 kids.

Next set up a proportion.

38,000 total 30 total kids
------------------ = --------------------
16,720 kids x

For 38,000 to get to 30, you have to divide 38,000 by 1,266.67.

This means that you also have to divide 16,720 by 1,266.67.

This gets you 13.

#3) PLEASE HELP WITH QUESTION, MARKING BRAINLIEST + POINTS :)

$\boxed { \boxed { a_n = a_1 + d(n - 1)}}$

$a_{14} = -33 , a_{15} = 9,$

$a_{14} = a_1 + d(14 - 1) = -33$
$a_1 + 13d = -33$

$a_{15} = a_1 + d(15 - 1) = 9$
$a_1 + 14d = 9$

So the two equations:
$a_1 + 13d = -33$ ----------------- ( 1 )
$a_1 + 14d = 9$ ----------------- ( 2 )

(2) - (1) :
$d = 42$ ----------------- (Sub into 1)

$a_1 + 13(42) = -33$
$a_1 + 546= -33$
$a_1 = -33 - 546$
$a_1 = -579$

$\boxed { \boxed { a_n = -578 + 42(n - 1)}}$
