Can anybody answer this
Answer:
answer is letter A
Step-by-step explanation:
I just know I used a calculator
A stereo is normally $540, and today is on sale for 25% off how much do you save by buying it today
Using the percentage concept, the amount saved by purchasing today is $135
Given the Parameters :
Normal price = $540Discount on sale = 25%The amount saved saved by buying at the discounted price can be calculated thus :
Normal price × discount rateAmount saved = $540 × 25%
Amout saved = $540 × 0.25
Amout saved = $135.
Hence, the amount saved by purchasing today is $135.

Based on the information given the amount save by buying today is $135.
First step is to calculate the discount
Discount=540 - (25%×$540)
Discount=$540 - $135
Discount =$405
Second step is to calculate the amount save.
Saved amount=$540-$05
Saved amount=$135
Inconclusion the amount save by buying today is $135.

assume that the height of your cylinder is 8 inches. consider a as a function of r, so we can write that as a(r)=2πr2+16πr. what is the domain of a(r)? in other words, for which values of r is a(r) defined? part b: continue to assume that the height of your cylinder is 8 inches. write the radius r as a function of a. this is the inverse function to a(r), i.e to turn a as a function of r into. r as a function of a.
Step-by-step explanation:
The domain of A(r) is [tex]r \geq 0.[/tex] The expression for A(r) is
[tex]A(r) = 2\pi r^2 + 16\pi r[/tex]
Let's write A(r) as simply A and divide the equation by [tex]2\pi[/tex] to get
[tex]r^2 + 8r = \dfrac{A}{2\pi}[/tex]
We can complete the square on the left hand side by adding 16 to both sides:
[tex]r^2 + 8x + 16 = \dfrac{A}{2\pi} + 16[/tex]
[tex]\Rightarrow (r + 4)^2 = \dfrac{A}{2\pi} + 16[/tex]
Taking the square root of the equation above and then solving for r, we get
[tex]r = -4 \pm \sqrt{\dfrac{A}{2\pi} + 16}[/tex]
In this exercise we have to use our knowledge about cylinders to calculate the function that best represents its value:
[tex]r=-4+\sqrt{\frac{A}{2\pi} +16}[/tex]
The area domain of A can be written as:
[tex]A(r)=2\pi r^2+16\pi r[/tex]
Let's write A(r) as simply A and divide the equation by [tex]2 \pi[/tex]to get:
[tex]r^2+8r=\frac{A}{2\pi}[/tex]
Now we can sum on both sides like:
[tex]r^2+8X+16=\frac{A}{2\pi}+16\\(r+4)^2=\frac{A}{2\pi}+16[/tex]
Taking the square root of the equation above and then solving for r, we get:
[tex]r=-4+\sqrt{\frac{A}{2\pi} +16}[/tex]

Which function in problems 1-3 has a horizontal asymptote at y=0?
9514 1404 393
Answer:
numerator: 3; denominator: 2; slant aymptotenumerator: 2, denominator 4; y = 0 asymptotenumerator 2, denominator: 2; y = 5/3 asymptoteStep-by-step explanation:
We have to assume you intend everything to the right of the slash (/) to be denominator. Ordinarily, only the first factor would be considered denominator according to the Order of Operations.
ab/cd = (ab/c)d . . . according to the order of operations.
__
The degree of the numerator or denominator is essentially the number of factors involving x.
1. The numerator has 3 factors, hence degree 3. The denominator has 2 factors, hence degree 2. The degree of the numerator is 1 more than the degree of the denominator, so the function will have a slant asymptote.
degrees: num/den = 3/2
__
2. The numerator has 2 factors, hence degree 2. The denominator has one binomial factor and 3 factors of x, hence degree 4. The degree of the denominator is higher than the degree of the numerator, so the function will have y = 0 as its horizontal asymptote.
degrees: num/den = 2/4 --- y = 0 horizontal asymptote
__
3. The numerator has 2 factors, as does the denominator. Hence the degree of each is 2. The horizontal asymptote will be a constant equal to the ratio of the leading coefficients: y = 5/3.
degrees: num/den = 2/2

Find the area of a trapezoid. With a base of 1 1/2 cm a height of 4 cm and a bottom base with 3 1/2 cm
Answer:
[tex]A=10cm^{2}[/tex]
Step-by-step explanation:
The formula to find the area of a trapezoid is,
Area = [tex]\frac{1}{2} *(a +b)*height[/tex]
(a+b) ⇒ Sum of the parallel sides
Let us solve now.
[tex]A =\frac{1}{2} *(a +b)*height[/tex]
[tex]A=\frac{1}{2} *(1\frac{1}{2} +3\frac{1}{2} )*4[/tex]
[tex]A=\frac{1}{2} *(\frac{3}{2} +\frac{7}{2} )*4[/tex]
[tex]A=\frac{1}{2} *(\frac{10}{2} )*4[/tex]
[tex]A=\frac{1}{2} *(5 )*4[/tex]
[tex]A=\frac{1}{2} *20[/tex]
[tex]A=10cm^{2}[/tex]
Hope this helps you.
Answer:
The area of trapezoid is 10 cm².

You are traveling to a football game. You tell your friends you traveled 70 miles per hour while on the interstate. You know however, that at one point you glanced at your speedometer and it read 68 miles per hour. Which is your average speed and which is your instantaneous speed?
The average speed is 70 miles per hour and the instantaneous speed is 68
miles per hour.
The average speed is the total distance travelled divided by the elapsed time
while the instantaneous speed is the accurate speed covered by the object
at a given instant of time.
Mathematically,
average speed = total distance travelled by the object / total time taken by
the object
Instantaneous speed = distance of an instant / time of an instant.
Therefore,
The average speed is 70 miles per hour.
The instantaneous speed is 68 miles per hour.

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
(x, y) → (x + 5, y – 3)
(x, y) → (x + 5, y + 3)
(x, y) → (x – 3, y + 5)
(x, y) → (x + 3, y + 5)
Answer:
3rd option
Step-by-step explanation:
A translation of 5 units up , in the positive y- direction means add 5 to the y- coordinate.
A translation of 3 units left, in the negative x- direction means subtract 3 from the x- coordinate.
Then translation rule is
(x, y ) → (x - 3, y + 5 )
