What is (5*3)^2+3 PLEASE need help

Answers

We need to solve this by PEMDAS. P=parenthesis, E=exponents, M=multiplication, D=Division, A=Additions, S=Subtraction. First we solve this problem by solving the inside of the parenthesis, 5*3, which is 15. The next step is E, exponents, we use 15 to the second power to get 225, and then we add 3 to the 225, and the total of this problem is 228.
The correct answer is 228

A spinner is divide into 10 equal sections numbered from 1 to 10. You SPIN the spinner once. What is P(5)? A.)1/3
B.)1/2
C.)1/10
D.)1/4

Answers

The probability of spinning a 5 would be C. 1/10. Since none of the numbers repeat, you have an equal chance at spinning any of the numbers... 1/10.

Answer: B: P(not 1)= 10%

Step-by-step explanation:

i put C and it was wrong. showed me B is correct

For questions 1-7, use the following functions to answer the questions: f(x)x^2+5x g(x)=3x-4/2

Answers

Answer:

f(4) = (4)² + 5(4) = 36.

g(9) = [3(9) - 4]/2 = 23/2.

f(-3) = (-3)² + 5(-3) = -6.

g(-6) = [3(-6) - 4]/2 = -11.

Set f(x) = 14.

=> x² + 5x = 14

=> x² + 5x - 14 = 0

=> (x + 7)(x - 2) = 0

=> x = -7 or x = 2.

Set g(x) = -28.

=> (3x - 4)/2 = -28

=> 3x - 4 = -56

=> 3x = -52

=> x = -52/3.

Answer:

36

11.5

6

-11

-2, 7

-17.333 / - 17⅓

Step-by-step explanation:

f(4) = 4² + 5(4) = 16+20 = 36

g(9) = 3(9)-4 ÷ 2 = 23÷2 = 11.5

f(-3) = (-3)²+5(-3) = 9 - 15 = 6

g(-6) = 3(-6)-4 ÷ 2 = - 22 ÷ 2 = - 11

f(x) = 14

x² - 5x = 14

x² - 5x - 14 = 0

(x+2) (x-7) = 0

x = - 2 or x = 7

g(x) = -28

(3x - 4)/(2) = - 28

3x - 4 = - 56

3x = - 52

x = - 52/3 = - 17 ⅓

Find the nth term of 14,22,30,38

Answers

first find the gap which is 8. 
Then you write 8N. To get 14 what do you have to do to the 8? Add 6 so the nth term is 8N+6
