f(x) = 3x2 - 2x g(x) = x + 4 When finding f(x) · g(x), what could the first step look like? A) 3x2 + 12x2 - 2x2 - 8x B) 3x2 + 7x
Anna71 [15]

(3x^2 - 2x)(x + 4)

<em><u>First step would be: distributive property.</u></em>

3x^3 + 12x^2 - 2x^2 - 8x

<em><u>Combine like terms.</u></em>

3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.

Your answer is D.

I'M TERRIBLE AT MATH SOMEONE HELP, WILL GIVE BRAINLIEST
jonny [76]

Answer:

D) -1.8, -1 1/2 , 0.3 , 3/4 , 1

Step-by-step explanation:

Change all of the given terms to either fractions or decimals. Generally decimals are easier:

3/4 = 0.75

-1.8 = -1.8

1 = 1.0

-1 1/2 = -1.5

0.3 = 0.3

Order from least to greatest:

-1.8 , -1.5, 0.3 ,  0.75 , 1.0

or

-1.8, -1 1/2 , 0.3 , 3/4 , 1

Paul bought a 15-year treasury bond for a face amount of $600. The 2.5% interest will be compounded quarterly. What will the fut
Alika [10]
First, we convert the interest such that it is compounded annually. The formula would be:

ieff = (1 + i/m)^m - 1
where m = 4, since there are 4 quarters in a year
ieff = (1 + 0.025/4)^4 - 1
ieff = 0.0252

Then we use this for this equation:
F = P(1 + i)^n, where F is the future worth, P is the present worth and n is the number of years
F = $600(1 + 0.0252)^15
F = $871.53

PLEASE HELP ME
sineoko [7]

Answer:

C. Exponential

Step-by-step explanation:

If the function is linear, the differences will be equal.

d₁ = y₁ − y₀ = 4.2 − 0.6 = 3.6

d₂ = y₂ − y₁ = 29.4 − 4.2 = 25.2

d₃ = y₃ − y₂ = 205.8 − 29.4 = 176.4

d₄ = y₄ − y₃ = 1440.6 − 205.8 = 1234.8

The differences are not equal, so this is not linear.

If the function is quadratic, the differences of the differences will be equal.

d₂ − d₁ = 25.2 − 3.6 = 21.6

d₃ − d₂ = 176.4 − 25.2 = 151.2

d₄ − d₃ = 1234.8 − 176.4 = 1058.4

The differences of the differences are not equal, so this is not quadratic.

If the function is exponential, the ratios will be equal.

r₁ = y₁ / y₀ = 4.2 / 0.6 = 7

r₂ = y₂ / y₁ = 29.4 / 4.2 = 7

r₃ = y₃ / y₂ = 205.8 / 29.4 = 7

r₄ = y₄ / y₃ = 1440.6 / 205.8 = 7

The ratios are equal, so the function is exponential.
