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.
What is the slope of the line whose equation is 3x – 4y – 16 = 0
Answer:
Slop is 3/4
Step-by-step explanation:
3x - 4y - 16 = 0
- 4y = -3 x + 16
y= ( -3 / -4 ) x + 16 / ( -4 )
y= (3/4) x - 4

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
If f(x)= x/2-2 and g(x)= 2x^2+x-3, find (f+g)(x).

(f+g)(x)= [tex]\frac{x}{2} -2[/tex] + [tex]2x^{2} +x-3[/tex] = [tex]2x^{2} + \frac{3}{2} x - 5[/tex]
What is the equation of a line that has a slope of 0 and passes through (5, −2)?
y=-2

(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.

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.

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.
