Answer:

Step-by-step explanation:

g(-2) = 5 - 3(-2)^2 = 5 - 3(4) = 5 - 12 = -7

Answer:

g(-2)=-7

Step-by-step explanation:

start by replacing x with -2

g(-2)=5-3(-2)^2

-2^2 is 4 so

g(-2)=5-3(4)

g(-2)=5-12

g(-2)=-7

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 14 feet a
Evgesh-ka [11]

Answer:

11.8 % empty

Step-by-step explanation:

volume of cylinder : pi × r² × h

attention ! the question gives us diameter, so for radius we need to cut them in half.

Va = pi × (14/2)² × 9 = pi×49×9 = 1385.44236... ft³

Vb = pi × (10/2)² × 20 = pi×25×20 = 1570.79633... ft³

after filling B with everything in A there is still some empty volume in B

Vb empty = Vb - Va = 185.35397... ft³

so,

100% Vb = 1570.79633... ft³

1% Vb = 15.7079633... ft³

so, how often does 1% of the total volume of B fit into the remaining empty volume of B ?

185.35397... / 15.7079633... = 11.8%

PLEASE HELP!
Dafna11 [192]

Answer:

It will take<u> 8.17 days</u> for a news story to reach 1,500,000 shares.

Step-by-step explanation:

Note: The correct exponential model is as follows:

y = 5⋅7^x ......................................... (1)

Where:

y = 1,500,000

x = ?

Substituting y = 1,500,000 into equation (1), we have:

1,500,000 = 5⋅7^x ........................ (2)

Taking the natural log of both sides of equation (2) and solve for x, we have:

ln1,500,000 = xln5.7

x = ln1,500,000 / ln5.7

x = 14.2209756660724 / 1.7404661748405

x = 8.17241379310345

Approximating to 2 decimall places, we have:

x = 8.17

Therefore, it will take 8.17 days for a news story to reach 1,500,000 shares.
