Answer:
-5.2f - 47.1
Step-by-step explanation:
It's easiest if you put all the like terms and numbers together and solve from there.
-2.6f - 2.6f + 0.45 + 0.45 - 16 - 16 - 8 -8
-5.2f + 0.9 - 32 - 16
-5.2f - 47.1

Ines has saved $5. She doubles the amount she saves each week. Does the function have a constant difference or a constant ratio? Does this represent an exponential function?
Answer:
The function have a constant ratio
No, it does not represent an exponential function.
Step-by-step explanation:
As given,
Ines has saved $5. She doubles the amount she saves each week.
⇒ In first week she saved = $5
In second week she saved = 2×$5 = $10
In third week she saved = 2×$10 = 20
In fourth week she saved = 2×$20 = 40
and so on..
∴ we get the series
5, 10, 20, 40 ,.......
If the series is given as a, b, c, d, ..... , then
The common difference is defined as d = b-a = c-b
The common ration is defined as r = [tex]\frac{b}{a} = \frac{c}{b}[/tex]
Here, in the given question
The series is - 5, 10, 20, 40
This has no common difference , d = 10 - 5 (= 5 )≠ 20 - 10 (= 10)
As 5 ≠ 10
So the function does not define common difference .
Now,
This has common ratio , r = [tex]\frac{10}{5} (=2) = \frac{20}{10}(=2)[/tex]
As 2 = 2
So, the function represent common ratio
Now,
The function does not represent an exponential function because it is increased by common ratio.

Find the area of the shaded region
Answer:
The shaded area is equal to [tex]2500\pi - 1296\pi = 1204\pi.[/tex]
Step-by-step explanation:
The shaded area is equal to the area of the outer circle minus the area of the inner circle.
The area of the outer circle is equal to [tex]r^2\pi = 50^2\pi = 2500\pi[/tex] feet.
The area of the inner circle is equal to [tex]r^2\pi = 36^2\pi = 1296\pi[/tex] feet.
So the area of the shaded area is equal to [tex]2500\pi - 1296\pi = 1204\pi.[/tex]

how do I write a polynomial when given the zeros
Given the zeros of a polynomial, you can very easily write it -- first in its factored form and then in the standard form. Subtract the first zero from x and enclose it in parentheses. This is the first factor. For example if a polynomial has a zero that is -1, the corresponding factor is x - (-1) = x + 1.
Answer:
Subtract the first zero from x and enclose it in parentheses. This is the first factor. For example if a polynomial has a zero that is -1, the corresponding factor is x - (-1) = x + 1.
Raise the factor to the power of the multiplicity. For instance, if the zero -1 in the example has a multiplicity of two, write the factor as (x +1)^2.
Repeat Steps 1 and 2 with the other zeros and add them as further factors. For instance, if the example polynomial has two more zeros, -2 and 3, both with multiplicity 1, two more factors -- (x +2) and (x -3) -- must be added to the polynomial. The final form of the polynomial is then ((x +1)^2)(x +2)(x -3).
Multiply out all the factors using the FOIL (First Outer Inner Last) method to get the polynomial in the standard form. In the example, first multiply (x + 2)(x - 3) to get x^2 + 2x - 3x - 6 = x^2 - x - 6. Then multiply this with another factor (x + 1) to get (x^2 - x - 6)(x + 1) = x^3 +x^2 - x^2 - x - 6x - 6 = x^3 - 7x - 6. Finally, multiply this with the last factor (x + 1) to get (x^3 - 7x - 6)(x + 1) =x^4+x^3-7x^2-7x-6x-6 = x^4 + x^3 - 7x^2 - 13x - 6. This is the standard form of the polynomial.
River C is 100 miles longer than River D. If the sum of their lengths is 5,500 miles, what is the length of each river?
Answer:
river C is 2850 and river B is 2650
in the picture, thanks :)
HELP ME OUT PLEASE!!!
Answer:
So the scale factor would be the length of the new rectangle divided by the length of the corresponding side for the original rectangle. So the scale factor is 1/2. Note: If you're going from a bigger shape to a smaller one, you know that the scale factor must be less than 1.

Question 3 what is the answer
2.) Kyle swims a 1/2 mile every 1/4 hour. How far will he swim in one hour?
Answer:
I think it would be 2 miles
Step-by-step explanation:
This is because 1/4 of an hour is 15 minutes
so in 15 minutes he swims half a mile
4 x 15 = 60 minutes
so 4 x 1/2 = 2miles

Please help me! STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12
ST = 23 units
SU = 23 units
TU = 23 units
Step-by-step explanation:
For an equilateral triangle, all the angles are equal. Also, all the sides are equal.
Hence given that the sides ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x
ST = 2x - 1
SU = 5x - 37
TU = x + 11
Since ST = SU = TU
2x - 1 = 5x - 37
collect like terms
37 - 1 = 5x - 2x
36 = 3x
Divide both 3
36/3 = x
x = 12
Therefore
ST = 2x - 1 = 2(12) - 1 = 23 units
SU = 5x - 37 = 5(12) - 37 = 23 units
TU = x + 11 = 12 + 11 = 23 units

Answer:
m∠M = 47°
m∠R = 124°
Step-by-step explanation:
HOME = TRAP
Judging buy the picture there is only one corner that sticks out compared to the rest of the angles. Meaning that A and M are the same because they are the only angles that are easily identical to each other. Then match the letters using this information
m∠A = m∠M
m∠R = m∠O
m∠T = m∠H
m∠P = m∠E
Now all you need to find is m∠R and m∠M
m∠A = m∠M means m∠M = 47° since m∠A is 47°
Same concept goes for m∠R = m∠O.

5(2Y - 3) – 4y = 8 – 2y - 15
Justify this please
Answer:
y=1
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2y−3)−4y=8−2y−15
Step 1: Simplify both sides of the equation.
5(2y−3)−4y=8−2y−15
(5)(2y)+(5)(−3)+−4y=8+−2y+−15(Distribute)
10y+−15+−4y=8+−2y+−15
(10y+−4y)+(−15)=(−2y)+(8+−15)(Combine Like Terms)
6y+−15=−2y+−7
6y−15=−2y−7
Step 2: Add 2y to both sides.
6y−15+2y=−2y−7+2y
8y−15=−7
Step 3: Add 15 to both sides.
8y−15+15=−7+15
8y=8
Step 4: Divide both sides by 8.
The value of y is 1
Given the equation 5(2Y - 3) – 4y = 8 – 2y - 15
Expand
10Y - 15– 4y = 8 – 2y - 15
6y - 15 = -7 - 2y
Collect the like terms
6y + 2y = -7 + 15
8y = 8
Divide both sides by 8
8y/8 = 8/8
y = 1
Hence the value y of is 1
