Answer:
$370.85
Step-by-step explanation:
He started off with $165.85. So all we need to do is multiply $20.50 x 10 = $205. We need to add 165.85 + 205 = $370.85
So after 10 weeks there will be $370.85.

What is the value of x? Pls help
Answers
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20

Step-by-step explanation:
The formula for exponetial equation decay is
[tex]y = a(b) {}^{x} [/tex]
where a is the initial value and b is the decay factor.
A will be 56 since that our initial value.
b will be 0.9 since we are constantly decaying by 0.9.
so our equation is

Determine all the transformations that have happened to f(x) = (x + 4)2 + 2 compared to
f(x) = x2
Answers
Answer:
Folow the steps to learn what transformations were determined.
Step-by-step explanation:
First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.
X Y
2 4
1 1
0 0
-1 1
-2 4
Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.
Vertical Shifts:
f(x) + c moves up,
f(x) - c moves down.
Horizontal Shifts:
f(x + c) moves left,
f(x - c) moves right.
The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).
Determine if the triangles are congruent. If they are, state why.

Plot the zeros of this function:
f(x) = (x – 1)(x – 7).
Answers
Answer:
Zeros of the given function are x = 1, 7
Step-by-step explanation:
Given function is,
f(x) = (x - 1)(x - 7)
For zeros of the function,
f(x) = 0
(x - 1)(x - 7) = 0
(x - 1) = 0
x = 1
(x - 7) = 0
x = 7
Therefore, zeros of the given function are x = 1, 7
We can find the zeros by suing a graphing tool.
how do you know when the solution of equations is a precise answer and when it is an approximate answer?
Answers
Answer:
an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11

A certain drug is made from only two ingredients: compound A and compound B. There are 4 milliliters of compound A used for every 7 milliliters of compound B. If a chemist wants to make 1012 milliliters of the drug, how many milliliters of compound A are needed?
These are proportions.
Answers
Answer:
368 milliliters.
Step-by-step explanation:
Compound A + Compound B = 1 drug
4 + 7 = 1 drug
11 milliliters = 1 drug, so 1012 milliliters = 92 drugs
Multiply the compounds by the amount of drugs, e.g.
4 x 92 = 368 ( Compound A )
7 x 92 = 644 ( Compound B )
368 + 644 = 1012
368 milliliters of Compound A are needed to make 1012 milliliters of the drug.
Hope this helps :)
