A circle has a radius of 50 cm. Which one of these is closest to the area?
A. 314 cm
B. 15,708 cm
C. 7,854 cm
D. 157 cm
I need help ASAP!!!
Answer:
The answer is C!
Step-by-step explanation:
I don't have an explanation, it just came to me, sorry..Hope this helps though!
Answer:
7,854 cm
Step-by-step explanation:
We know that Area of the circle is given by:-
Area = \pi r^2πr2
, where r is the radius of the circle.
Given, A circle has a radius of 50 cm.
i.e. r= 50 cm
Then the circle would be Area = \pi(50)^2=(3.14)(2500)=7853.98163397\approx78547\ cm^2π(50)
=(3.14)(2500)=7853.98163397≈78547 cm
Thus, the area of the circle is approximately 7,854\ cm^27,854 cm

Question 3
find y intercept of the line using (2,1), (3,-10)
[tex]\huge\boxed{(0, 23)}[/tex]
Hey there! We'll solve this problem in three main steps. First, we'll find the slope of the line. Then, we'll find the equation line in point-slope form. Finally, we'll change the equation to slope-intercept form so we can tell what the y-intercept is.
We can use the slope formula, where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two known points on the line.
[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}&&\smash{\Big|}&&\text{Use the slope formula.}\\&=\frac{-10-1}{3-2}&&\smash{\Big|}&&\text{Substitute in the known values.}\\&=\frac{-11}{1}&&\smash{\Big|}&&\text{Subtract.}\\&=\boxed{-11}&&\smash{\Big|}&&\frac{x}{1}=x\end{aligned}[/tex]
Now that we have the slope, we can use it together with one of the points to get the line in point-slope form. Then, we can distribute and add to get the line in slope-intercept form.
[tex]\begin{aligned}y-y_1&=m(x-x_1)&&\smash{\Big|}&&\text{Use point-slope form.}\\y-1&=-11(x-2)&&\smash{\Big|}&&\text{Substitute in the slope and one point.}\\y-1&=-11x+22&&\smash{\Big|}&&\text{Distribute.}\\y&=-11x+\boxed{23}&&\smash{\Big|}&&\text{Add $1$ to both sides.}\end{aligned}[/tex]
We can now clearly see that the y-intercept of the line is [tex]23[/tex], or [tex](0, \boxed{23})[/tex] as a point.

y 1 2 3 4
C) x 6 6 7 7
y 2 3 4 5
D) x 2 -2 4 -4
y 8 8 12 12
Answer:

Step-by-step explanation:
Every time the y-value increases by one, the function multiplies the x-value by -1
Answer:
Option D
Step-by-step explanation:

A company runs food service concessions for sporting events throughout the country. Their marketing research department chose a particular football stadium to test market a new jumbo hot dog. It was found that the demand for the new hot dog is given approximately by p=8−ln(x),5≤x≤500, where x is the number of hot dogs (in thousands) that can be sold during one game at a price of p dollars. If the company pays 1 dollar for each hot dog, how should the hot dogs be priced to maximize the profit per game?
Answer:
$3
Step-by-step explanation:
Given that:
p = 8 - ln(x) when 5 < x < 500
where;
x = The total number of dogs sold
Then;
The total revenue = x * p
R = x(8 - ln(x))
R = 8x - xln(x)
The Company thus pays 1 dollar per dog
i.e.
The total cost C = 1 * x = x
Then: Profit = R - C
P = 8x - xln(x) - x
P = 7x - xln(x)
Differentiating P in respect to x
dP/dx = 7 - d/dx(xln(x))
dP/dx = 7 - x*d/dx(ln(x)) - ln(x)*d/dx(x)
dP/dx = 7 - x(1/x) - ln(x)
dP/dx = 6 - ln(x)
Since this must be maximized, dP/dx is set to be equal to 0
6 - ln(x) = 0
ln(x) = 6
x = e^6
Now, p = 8 - ln(x)
Plug in the value of x :
p = 8 - ln(e^5)
p = 8 - 5
p = 3
Therefore, each dog must be priced at $3 to maximize the profit.
A TV that usually sells for $192.15 is on sale for 20% off. If sales tax on the TV is 6%, what is the price of the TV, including tax?
Answer:
$162.94
Step-by-step explanation:
Because 20% off of 192.15 = $162.94 and
$153.72 + (6.0%) $9.22 = $162.94
Find sin A and cos A
A) sin A = 3/5; cos A = 4/5
B) sin A = 4/5; cos A = 3/5
C) sin A = 5/4; cos A = 4/5
D) sin A = 4/3; cos A = 3/4
Answer:
B
Step-by-step explanation:
sinA=opp/hyp
sinA=16/20=4/5
cosA=adj/hyp
cosA=12/20=3/5
Answer:
We found sinA= 3/5 and cosA=4/5
Option A is correct.
Step-by-step explanation:
The formula to find sin A is :
[tex]sin A = \frac{Perpendicular}{Hypotenuse}[/tex]
while the formula to find cos A is:
[tex]cosA=\frac{Base}{Hypotenuse}[/tex]
So, in the figure given:
Base = 16
Perpendicular = 12
Hypotenuse = 20
Now, finding sin A and cos A using formulas and above values
[tex]sin A = \frac{Perpendicular}{Hypotenuse}\\sin A = \frac{12}{20}\\sinA=\frac{3}{5}[/tex]
[tex]cosA=\frac{Base}{Hypotenuse}\\cosA=\frac{16}{20}\\cosA=\frac{4}{5}[/tex]
So, we found sinA= 3/5 and cosA=4/5
Option A is correct.

a sequence has an explicit rule f(n)=6 - n^2. find the first 3 terms.
help pretty pleaseeee
Answer:
5, 2, - 3
Step-by-step explanation:
To find the first 3 terms substitute n = 1, 2, 3 into the explicit rule, that is
f(1) = 6 - 1² = 6 - 1 = 5
f(2) = 6 - 2² = 6 - 4 = 2
f(3) = 6 - 3² = 6 - 9 = - 3
The first 3 terms are 5, 2, - 3
Mahmoud is doing some plumbing repairs. He runs a pipe through a rectangular wall making a 70 angle. Afterward, he puts the pipe
through another wall which is parallel to the first. Mahmoud can therefore assure the homeowner that the pipe forms a ____ angle
with the second piece of wall.
Answer:
The correct option is;
(D) 70°
Step-by-step explanation:
By running the pipe through the first wall, to the second wall which is perpendicular to the first, we have;
The angle the pipe makes = 70°
Therefore, due to the spring back effect the formed by the pipe when bent 90° is 70°
Therefore, By running the pipe from the second wall, to the third wall which is parallel to the first, and perpendicular to the second wall, the angle the pipe forms is also a 70° angle
Mahmoud can therefore assure the home owner that the pipe forms a 70° angle with the second piece of the wall.

When faced with needing additional money during college, which option is NOT true?
Answer:
stealing
Step-by-step explanation:
Answer: C. Paying with additional loans can lead to connections and opportunities
Step-by-step explanation
The options to the questions are:
A. Taking on a job can cut into study time
B. Paying with credit cards can end up costing more money
C. Paying with additional loans can lead to connections and opportunities
D. Taking on a job can make connections that lead to opportunities
Answer:
C. Paying with additional loans can lead to connections and opportunities
Step-by-step explanation:
When faced with needing additional money during college, an individual may choose to take on a job so as to get extra money to finance his or her needs. However, such a venture often leads to a reduction in study time, as working on jobs will also need its own time of execution.
Also, paying for financial needs during college days with a credit card can lead to counting more money on the card. This implies that one can accumulate credit card rewards which can be in form of cashback, or points from certain purchases when using a credit card.
More so, taking a job during college days, will definitely bring connections with different people, and thereby leads to opportunities.
However, paying with additional loans will never lead to connections and opportunities, but rather more debt, that the debtor will have to pay, which may take months or years. And it can only be a burden on the debtor.
Hence, when faced with needing additional money during college the option that is NOT true is Paying with additional loans can lead to connections and opportunities
Find A U { }. If A is any given set
Answer:
A U { } = A
Step-by-step explanation:
Union is one of the operations that are performed on sets. In union, the elements of involved sets are combined and repetitive elements are removed (written only once)
Given
A U { } = ?
Whenever union will be taken of any set and empty set the answer will be the set.
Similarly, when union of set A will be taken with empty set the result will be set A.
Hence,
A U { } = A
