Answer 1
Answer:

Answer:

degree = 6

Step-by-step explanation:

Given f(x)=3x^2, and g(x)=4^3+1, we can find the composition of functions: fog(x) by applying the definition of composition and performing the needed algebra.

Recall that the composition of functions is defined as: fog(x)=f(g(x)), where we use as input for the function f(x) the actual expression in terms of "x" of the function g(x):

f(g(x))=f(4x^3+1)\nf(g(x))=3(4x^3+1)^2\nf(g(x))=3\,(4x^3+1)\,(4x^3+1)\nf(g(x))=3\,[16x^6+4x^3+4x^3+1]\nf(g(x))=3\,[16x^6+8x^3+1]\nf(g(x))=48x^6+24x^3+3

Therefore, the degree of this expression is "6" (the highest power at which the variable "x" appears)

If Joseph runs 1/5 mile in 1/30 of an hour, what is his speed in miles per hour?

Answers

Answer: 6 miles per hour

Step-by-step explanation:

1/30 of an hour is 2 minutes

he ran 1/5 of a mile in 2 minutes so

5/5 of a mile = 1 mile  

5 x 2 min = 10 minutes

Take 6 x 10 minutes to = 1 hour

So 6 x 1 hour is 6 miles and hour.

How do you simplify 7 (2x+10) thanks in advance

Answers

the only thing you should do is to multiply 7 by 2x and 10. 
so you will have: (7*2x) + (7*10) = 14x + 70 :)))

What is the sum of the expressions (12x+6)+(12x−4)?

Answers

Answer: 24

Explanation: You’ll have to multiply the numbers. 12x6 = 72. 12x-4 = -48.

72 + (-48)
You remove the parentheses because when there’s a “+” in the front of an expression in parentheses, the expression remains the same.

Therefore, it’s just 72-48. Subtract that and you’ll get 24. Hope this helps! (:

Cam you look at this picture. I really need help for #2, #5, #8, #9, #10

Answers

# 2 is true
# 5 is 0.375 
#8 is 8 solutions
#9 is %25
#10 is %37.5

hope this helps

for number 2: 4 times 4 equals 16 is that's why its the square root of 16. 
for number 8: with red there are 3 options plus the red option so that's 4 plus the same thing with blue so that's 8.
for number 9: there is a 2/8 chance of getting that. 2/8= 25%
for number 10: there is a 3/8 chance of landing on it. 3/8= 37.5%
