Answer:

Step-by-step explanation:

Given a polynomial divided by a factor (x + h) then the remainder is f(- h)

Given

f(x) = 3 $x^{4}$ + 2x³ - x² + 2x - 19 divided by (x + 2)

To find remainder evaluate f(- 2)

f(- 2) = 3 $(-2)^{4}$ + 2(- 2)³ - (- 2)² + 2(- 2) - 19

= 3(16) + 2(- 8) - 4 - 4 - 19

= 48 - 16 - 4 - 4 - 19

= 5 → B

Michelle's father deposited $1,000 into a savings account when she was born. The annual interest rate is

Zarrin [17]

Answer:

0. $1,000 1. $1,045 2. $1,092.03 3. $1,141.17 4. $1,192.52. 5. $1,246.18 6. $1,302.26 7. $1,360.86 8. $1,422.10

Step-by-step explanation:

First you start with the beginning balance of $1,000 dollars, then you multiply that by 1.045 to get $1,045 dollars after one year. Then you multiply $1,045 by 1.045 to get $1,092.025 (monetarily correct, it would be $1,092.03) after the second year. Then you multiply $1,092.025 (keeping it un-rounded for precision) by 1.045 to get $1,141.16612 after the third year. Then you multiply $1141.16612 by 1.045 to get $1,192.5186 after the fourth year. Multiply $1,192.5186 by 1.045 to get $1,246.18193 after the fifth year. Multiply $1,246.18193 by 1.045 to get $1,302.26012 after the sixth year. Multiply $1,302.26012 by 1.045 to get $1,360.86182 after the seventh year. Multiply $1,360.86182 by 1.045 to get $1,422.10061 after the eighth year. Basically, Michelle is going to be a trust fund baby by the time she's twenty and she won't have to worry about college if she works hard and does well in high school.

Answer:

Infinitely many solutions

Step-by-step explanation:

7x - 11 = 5(x - 2) + 2x - 1

7x - 11 = 10x - 10 + 2x - 1

7x - 11 = 7x - 11

No matter what number you plugin, it will always be equal.

Find the measure of angle A.<br> A<br> 9x+6<br> 4x + 6<br> m/A=

Likurg_2 [28]

Answer:

angle A=30°

Step-by-step explanation:

$9x + 6 + 4x + 6 + 90 = 180 \\ 13x + 102 = 180 \\ 13x = 180 - 102 \\ 13x = 78 \\ \frac{13x}{ 13} = \frac{ 78}{13} \\ x = 6 \\ 4x + 6 = a \\ 4(6) + 6 = a \\ 24 + 6 = a \\ 30 = a$

Y+x=31, 150x+225y=5100.
y=-x+31
150x+225(-x+31)=5100
-75x=-1875
x=25 (adult tickets are $25)
31-25= 6 (child tickets are $6)
