Evaluate 12a for a = 4.
A. 8
B. 16
C. 48
D. 3
what is the value of 4 to the second power - 2 ( 3 times 5 + 1)
Answer:
4 to the second power = 16. that leaves us with 16 - 2 ( 3 x 5 + 1). next, multiply 3 x 5 = 15. that leaves us with 16 - 2 ( 15 + 1 ). next, add 15 + 1 = 16. that leaves us with 16 - 2 ( 16 ). next, multiply 2 ( 16 ) = 32. finally, subtract 16 - 32 = -16
Step-by-step explanation:
your answer is -16. hope this helps

Given the following functions:
f (x) = x2
g (x) = x − 3
Find the composition of the two functions and show your process:
Answer:
x^2 -6x +6
Step-by-step explanation:
f (x) = x^2
g (x) = x − 3
f(g(x)) = Substitute g(x) in for x in the function f(x)
= (x-3)^2 -3
=x^2 -3x-3x+9 -3
=x^2 -6x +6

Which expression is equivalent
Answer:
[tex](-7)^{-2}[/tex]
Step-by-step explanation:
In Exercises 9-12 solve y=f(x) for x then find the input when output is 2 9. F(x)=x+5 10. F(x)=2x-3 11. F(x)= 1/4x -1 12. F(x)= 2/3x+4
Step-by-step explanation:
Q9 . y = x + 5
x= y-5
× the input
y the output
x= -3
Q10.
y = 2x -3
y+3 = 2x
x = (y+3) ÷ 2
× = 5/2
= 2.5
Q11.
y = 1/4x - 1
y+1 = 1/4 x
4y+4 = x
x = 12
Q 12 .
y = 2/3x + 4
y-4 = 2/3x
3(y-4) = 2x
x = 3(y-4)/2
x = -3

f(x)=x^4+3, g(x)=x-7 and h(x)=square root of x then f(g(h(x))=
Answer:
x² - 28x√x + 294x - 1372√x + 2404
Step-by-step explanation:
f(x) = [tex]x^{4}[/tex] + 3
g(x) = x - 7
h(x) = √x
f(g(h(x))) - ?
g(h(x)) = √x - 7
f(g(h(x))) = [tex](\sqrt{x} -7) ^{4}[/tex] + 3 = ( √x - 7 )² × ( √x - 7 )² + 3 =
= (x - 14√x + 49)(x - 14√x + 49) + 3 =
= x² - 14x√x + 49x - 14x√x + 196x - 686√x + 49x - 686√x + 2401 + 3 =
= x² - 28x√x + 294x - 1372√x + 2404

Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)

Using these rules, we can simplify the left-side expression, then equate exponents of the same base.

Answer:
A and C.
Step-by-step explanation:
2 √75 + 3√50
= 2√(25*3) + 3√(25*2)
- so A is one.
2 √75 + 3√50
= 2√25√3 + 3√25√2
= 2*5√3 + 3*5√2
= 10√3 + 15√2
which is C.

You can reformulate the expression in a more easier way, by using the concept of fraction. And so you get :
[tex]\frac{55}{11(\frac{120}{2*(4+(10+5-7)} )} =\frac{55}{11(\frac{120}{2*(12)} )}=\frac{55}{11(\frac{120}{24} )}=\frac{55}{11*5} = \frac{55}{55} =1[/tex]

A rectangle's width is one-seventh its length, and its perimeter is 160 m. Find the dimensions of the rectangle.
Answer:
dimensions of the rectangle is 70m by 10m
Step-by-step explanation:
w = 1/7 X L
p = 160m
p = 2(L + W)
p = 2( L + L/7)
160/2 = (L + L/7)
80 =( 8L/7)
Make L subject of formula
L = 80 X 7/8
L = 10x 7
L = 70m
W = 1/7 X L
W = 1/7 X 70 = 10m
