What is the product of a+3 and -2a2+15a+6b2?
ankoles [38]

Answer: -2a^3 + 9a^2 + 45a + 18b^2 + 6ab^2

Step-by-step explanation:

(a + 3) * (-2a^2 + 15a + 6b^2)

We open the brackets with (a + 3)

a ( -2a^2 + 15a + 6b^2) + 3(-2a^2 + 15a + 6b^2)

Opening the brackets

= a * -2a^2 = -2a^3

a * 15a = 15a^2

a * 6b^2 = 6ab^2

3 * -2a^2 = -6a^2

3 * 15a = 45a

3 * 6b^2 = 18b^2

Let's arrange those values weve gotten together ,don't forget the signs each carry

= -2a^3 + 15a^2 + 6ab^2 - 6a^2 + 45a + 18b^2

Collect the like terms

= -2a^3 + 15a^2 - 6a^2 + 6ab^2 + 45a + 18b^2

= -2a^3 + 9a^2 + 6ab^2 + 45a + 18b^2

2. On December 31, Juan Carlos made a $ 7,000 deposit in an account that pays 2.975% interest compounded semi-annually. How much
inna [77]

Answer:$ 7425.89

Step-by-step explanation:

Formula to find the compound amount ( compounded semiannually) :-

A=P(1+\dfrac{r}{2})^{2n} , where P is the principal amount, r is rate of interest ( in decimal), and n is time in years.

Given : P= $7000

r=2.975%=0.02975

Time : n= 2

Then, The amount in account after 2 years:-

A=7000(1+\dfrac{0.02975}{2})^{2\times2}\\\\=7425.88565609\approx7425.89

Hence, Amount in account after 2 years = $ 7425.89
