y =
(Type an expression. Simplify your answer.)
Answer:
x^2+2x
Step-by-step explanation:
This function was shifted down 6 units.
It does not seem like this function was shifted horizontally since the x value is not being subtracted nor added inside the parentheses. Therefore, the original function would just be p(x) + 6, which would give us x^2+2x.

Step-by-step explanation:
total bill for repairs is 329.00
parts were 125.00
labor was 68.00 per hour
how many hours did you spend on labor?
Answer:
3 hours was spent on labor
Step-by-step explanation:
Key skills needed: Creating an equation, Solving an equation
1) The total cost is 329.00 (or 329). The parts are 125.00 (or 125), and the labor is 68 per hour.
2) If we say h is the number of hours of labor, then we can create this equation --> [tex]68h[/tex] (or 68 multiplied by "h") 68h would be the cost of labor, and we need to find the number of hours (h) as a number.
3) We can create this equation --> [tex]329 = 125 + 68h[/tex]
--> This equation can be made as the total cost (329) is equal to the parts (125) and the labor (68h)
4) Subtract 125 from both sides to get 68h by itself
--> 329 - 125 = 204 so 204 = 68h
--> Divide by 68 on both sides (204 divided by 68 is 3)
--> This means that h is 3.
Therefore, the number of hours spent on labor is 3.

Christi has $7,500 to invest. She was offered a simple annual interest rate of 4% for three years, but wants to look at other options. Which of the following changes will increase the interest she earns the most?
A-Simple interest, 4.2%, 3 years
B-Simple interest, 4.1%, 3 years
C-Simple interest, 4%, 3.25 years
D-Compound interest, 4%, 2.75 years
Christi can earn more interest if she invests $7,500 in Simple interest, 4%, 3.25 years, therefore, the correct option is c.
What is simple interest?Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,
[tex]SI = \dfrac{P \times R \times T}{100}[/tex]
where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.
The simple Interest she is currently getting,
[tex]SI = \dfrac{P \times R \times T}{100} = \dfrac{\$7,500 \times 4 \times 3}{100} =\$900[/tex]
A.)
[tex]SI = \dfrac{P \times R \times T}{100} = \dfrac{\$7,500 \times 4.2 \times 3}{100} =\$945[/tex]
B.)
[tex]SI = \dfrac{P \times R \times T}{100} = \dfrac{\$7,500 \times 4.1 \times 3}{100} =\$922.5[/tex]
C.)
[tex]SI = \dfrac{P \times R \times T}{100} = \dfrac{\$7,500 \times 4 \times 3.25}{100} =\$975[/tex]
D.)
[tex]CI = P(1+\dfrac{R}{100})^t -P = \$7,500(1+0.04)^{2.75}-\$7500 = \$854.16[/tex]
Hence, Christi can earn more interest if she invests $7,500 in Simple interest, 4%, 3.25 years, therefore, the correct option is c.

Ok so these are the answers that I can choose~ (Please and thank you <3)
A.44°
B.134°
C.90°
D.34°
Answer:
44 degrees, or A is your answer.
Step-by-step explanation:
You know angle A which is 46 and angle C which is 90, now all you have to do is solve to find angle B.
90+46=136
All the sides have to add up to 180 so simply do 180 - 136.
That will get you 44.
In a lab experiment, the decay of a radioactive isotope is being observed. At the beginning of the first day of the experiment the mass of the substance was 1000 grams and mass was decreasing by 14% per day. Determine the mass of the radioactive sample at the beginning of the 10th day of the experiment. Round to the nearest tenth (if necessary).
Answer:
120.91 grams
Step-by-step explanation:
multiply the initial amount by the percent that will remain to the power of n-1, n being the term number, or how many days that have passed.
f(x)=1000(0.85)^14-1
The mass of the radioactive sample at the beginning of the 10th day of the experiment is 221.30 grams if the mass was decreasing by 14% per day.
What is exponential decay?During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We have:
Mass of the substance = 1000 grams
Rate of decay = 14% per day = 0.14
Let's suppose the mass is m at the beginning of the 10th day of the experiment.
The equation for the exponential decay:
[tex]\rm E = m(1-r)^t[/tex]
[tex]\rm m = 1000(1-0.14)^1^0[/tex]
m = 1000×0.22130
m = 221.30 grams
Thus, the mass of the radioactive sample at the beginning of the 10th day of the experiment is 221.30 grams if the mass was decreasing by 14% per day.

If necessary, round your answer to the nearest tenth.
Answer:
10.4 ft
Step-by-step explanation:
think of it like a right triangle like in the picture with 12ft ladder as the hypotenuse
a²+b²=c²
6²+b²=12²
b²= 12²-6² =108
b=√108 = 10.392≈ 10.4 ft

A soft drink company wants to increase the volume of the cylindrical can they sell soft drinks in by 25%. The company wants to keep the 5-inch height of the can the same. The radius of the can is currently 2.5 inches. Approximately how much should the radius of the can be increased
Answer:
The radius should be increased by 0.295 inches.
Step-by-step explanation:
Volume of a cylinder:
In a cylinder, in which the base has radius [tex]r[/tex], and the height is [tex]h[/tex], the volume is given by:
[tex]V = \pi r^{2}h[/tex]
In this question:
5 inch height, radius of 2.5 inches. So the volume is given by:
[tex]V = \pi (2.5)^2(5) = 31.25\pi[/tex]
We want to increase the volume by 25%.
So, the new volume is given by:
[tex]1.25*31.25\pi = 39.0625\pi[/tex]
With this volume, keeping the height, the radius should be of:
[tex]V = \pi r^{2}h[/tex]
[tex]39.0625\pi = 5\pi r^{2}[/tex]
[tex]r^{2} = \frac{39.0625}{5}[/tex]
[tex]r^{2} = 7.8125[/tex]
[tex]r = \sqrt{7.8125}[/tex]
[tex]r = 2.795[/tex]
The radius should be of 2.795 inches, which is an increase of 2.795 - 2.5 = 0.295 inches.

Find the sum of the first 38 terms: 9/2,5,11/2,6,13/2
Answer:
Ths sum of the first 38 terms is [tex]\frac{1,045}{2}=522.5[/tex]
Step-by-step explanation:
Arithmetic Sequences
They are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
The sum of n terms of the sequence is
[tex]S_n=\frac{n}{2}( a_1 + a_n)[/tex]
The common difference is found by subtracting two consecutive terms:
[tex]r=a_{n+1}-a_n[/tex]
Using the first two terms:
[tex]r=a_2-a_1=5-\frac{9}{2}=\frac{1}{2}[/tex]
Now we find the term n=38
[tex]\displaystyle a_{38}=\frac{9}{2}+(38-1)\frac{1}{2}[/tex]
[tex]\displaystyle a_{38}=\frac{9}{2}+\frac{37}{2}=\frac{46}{2}=23[/tex]
The sum is:
[tex]\displaystyle S_{38}=\frac{38}{2}( \frac{9}{2} + 23)[/tex]
[tex]\displaystyle S_{38}=19( \frac{9+46}{2})[/tex]
[tex]\displaystyle S_{38}=19( \frac{55}{2})= \frac{1,045}{2}=522.5[/tex]
Ths sum of the first 38 terms is [tex]\mathbf{\frac{1,045}{2}=522.5}[/tex]
