Answer:
The student would need to save $9.17 more per month
Step-by-step explanation:

12x = 110
x = 110/12
x = $9.17
if x cubed = -8, what does x equal
Answers
Let's start the sum as follows:
x³ = 8
X × X × X = 8
This means there are 3 number which after Multiplication gives answer 8.
If 2 is multtiplied 3 times it will give you 8
Thus the answer of x is 2
x = 2.
x^3 = -8
The cube root of 8 is 2 = 2 x 2 x 2 is 8.
But, the answer is negative, which means that the cube root of -8 must be -2.
-2 x -2 x -2 = -8
x = -2

Answer:
Height = 9 cm which means Option C is the answerStep-by-step explanation:
In the question we are given ,
Volume of cylinder = 225π cm³Radius of cylinder = 5 cmAnd , we have to find the height of cylinder .
We know that ,
[tex]
\longrightarrow \pink{ \boxed{Volume \: of \: Cylinder = \pi r {}^{2}h }} \longleftarrow[/tex]
Our solution starts from here :
[tex] \longmapsto \: \pi \: r {}^{2} h = 225\pi[/tex]
Step 1 : Cancelling π with π :
[tex] \longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}[/tex]
Step 2 : Substituting value of radius which is 5 cm in the formula :
[tex] \longmapsto \: (5) {}^{2} \times h = 225[/tex]
[tex] \longmapsto \: 25h = 225[/tex]
Step 3 : Transposing 25 to right hand side :

Answers
Answer:
145°
Step-by-step explanation:
35+(5x+5)° = 180° (opposite angles sum up to 180°)
35+5x+5 = 180
40+5x = 180
5x= 180- 40
5x = 140
x = 28
therefore, the missing angle = (5x+5)°
= (5×28+5)= 140+5= 145°

Answers
The true statement for f(x)=b^x is the function is always decreasing function.
We have given,
f(x)=b^x where 0<b<1
What is the domain?Domain is all possible values of x for which any function is defined
We can select any values of x for which function
It will be defined for all real x
So, the domain is [tex](-\infty,\infty)[/tex]
The range is all possible values of y for which x is defined
we are given that b is positive
The value of the function will always be positive
So, the range is [tex](0,\infty)[/tex]
y>0
The x-intercept:
Set f(x)=0 and then we can solve for x
f(x)=b^x=0
x is undefined
The x-intercept does not exist
Increasing or decreasing:
Since, 0<b<1
The b is a positive value less than 1
As we increase the value of, [tex]b^x[/tex] will keep decreasing
This is decreasing function

interest: $_____
+$2,225.50
=$____(total)
Answers
Answer: $2400
Step-by-step explanation:
$2225.50 x 1.2% = $26.71 + $2225.50 = $2252.21 - Year 1
$2252.21 x 1.2% = $27.03 + $2252.21 = $2279.23 - Year 2
$2279.23 x 1.2% = $27.35 + $2279.23 = $2306.58 - Year 3
$2306.58 x 1.2% = $27.68 + $2334.26 = $2334.26 - Year 4
$2334.26 x 1.2% = $28.01 + $2362.27 = $2362.27 - Year 5
$2362.27 x 1.2% = $28.35 + $2362.27 = $2390.62 - Year 6
$2390.62 x 1.2% = $28.69 + $2390.62 = $2419.31 - Year 7
$2419.31 x 1.2% = $29.03 + $2419.31 = $2448.34 - Year 8

Use the function f(x) = x2 – 2x + 8 and the graph of g(x) to determine the difference between the maximum value of g(x) and the minimum value of f(
2.
Answers
Answer:
3 or 4, I am confused
Step-by-step explanation:
I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8
Find the value of f(x) for x = 2:
f(x) = x^2 – 2x + 8
f(2) = (2)^2 – 2*(2) + 8
f(2) = 4 - 4 + 8
f(2) = 8
=============
From the graph, we can find that g(2) = 11
The differece between g(2) and f(2) is thus:
11 - 8 = 3
3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2). If so, the maximum for g(x) is 12, at x = 3.
This would lead to a difference of 12 - 8, or 4. This is still not an option, so I'm confused. Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.

if angle 6 is 25 degrees how much is 7
Answers
Given:
Angle 6 = 25 degrees
To Find:
The value of Angle 7
Solution:
We know that,
the value of Angle 6 is equal to 25 Degrees
Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.
Therefore,
Angle 6 + Angle 7 = 180 degrees
This implies that,
25 degrees + Angle 7 = 180 degrees. (since Angle 6 = 25 Degrees)
Angle 7 = (180-25) degrees
Thus ,
Angle 7 = 155 degrees
Hence, Angle 7 is 155 degrees (Option 1)
