Step-by-step explanation: It is 2. You can use the vertex formula x= (-b/2a) 4/2(1), which is 2 and x=2 is the x intercept.
Two fish tanks have measurements as shown. Which tank has a greater volume? How much greater is its volume? Use the drop-down menus to explain and show your answer. Fish Tank A shows an area of base that is 25 square feet and a height of 8 feet. Fish Tank B shows an area of base that is 40 square feet and a height of 4 feet. The volume of fish tank A is Choose... cubic feet, and the volume of fish tank B is Choose... cubic feet. So fish tank Choose... has a greater volume. Its volume is greater by Choose... cubic feet. 10 / 14 9 of 14 Answered
Answer:
Volume of fish tank A is 200
Volume of tank B is 160
Tank A’s volume is greater by 40 cubic feet
Step-by-step explanation:
25 x 8 = 200
40 x 4 = 160
So:
200 - 160 = 40

The answer is C. A triangle has a total angle of 180°, therefore C. is more than 180°
Which equation can be used to solve for m∠1? m∠1 = one-half(a – b) m∠1 = one-half(a b) m∠1 = one-half(c – d) m∠1 = one-half(c d)

Density is mass per unit volume. The cost of the metals from the calculations performed is $1280.
What is density?Density is defined as the ratio of the mass of an object to its volume. We have the following information;
Mass of the metal = ?
Density of the metal = 5.2 g/cm3
height of the metal = 620 cm
radius of the metal = 19 cm
Volume of a cylinder = πr^2h = 3.142 * (19)^2 * 620 cm = 703242cm^3
Mass = density * volume = 5.2 g/cm3 * 703242cm^3
= 3657 Kg

Review the work showing the first few steps in writing a partial fraction decomposition.
StartFraction 4 x + 40 Over (x + 2) (x + 6) EndFraction = StartFraction A Over x + 2 EndFraction + StartFraction 16 Over x + 6 EndFraction
4x + 40 = A(x + 6) + B(x + 2)
4x + 40 = Ax + 6A + Bx + 2B
What is the partial fraction decomposition in terms of x?
Answer:
8/(x + 2) - 4/(x + 6)
Step-by-step explanation:
4x + 40 = Ax + 6A + Bx + 2B
Equating coefficients of x
4 = A + B (1)
Equating constant terms:
40 = 6A + 2B (2)
Multiply equation (1) by -2:
-8 = -2A - 2B .. (3)
Add (2) and (3):
32 = 4A
A = 32/4
A = 8.
4 = 8 + B
B = 4 - 8
B = -4.
The decomposition of the given partial fraction in terms of x is [tex]\frac{4x+40}{(x+2)(x+6)} =\frac{8}{(x+2)}-\frac{4}{(x+6)}[/tex].
What is partial fraction?The partial fraction is the result of writing a rational expression as the sum of two or more fractions.
According to the given question.
We have a partial fraction
[tex]\frac{4x+40}{(x+2)(x+6)} =\frac{A}{(x+2)} +\frac{B}{(x+6)}[/tex]
We have to decompose the above partial fraction in terms of x.
The above partial fraction can be written as
[tex]\frac{4x+40}{(x+2)(x+6)} =\frac{A(x+6)+B(x+2)}{(x+2)(x+6)}[/tex]
⇒[tex]4x+40 = A(x+6)+B(x+2)[/tex]
⇒[tex]4x + 40 = Ax + 6A + Bx + 2B[/tex]
⇒[tex]4x + 40 = x(A+B) +6A + 2B...(i)[/tex]
On comparing the coefficient of x and the constant terms.
[tex]A+B = 4..(ii)[/tex]
⇒[tex]A = 4 - B[/tex]
and, [tex]6A+2B = 40..(iii)[/tex]
⇒[tex]2(3A+B) = 40[/tex]
Substitute the value of A in (iii)
⇒[tex]2(3A+B) = 40[/tex]
⇒[tex]3A+B = 20[/tex]
⇒[tex]3(4-B)+B = 20[/tex]
⇒[tex]12 - 3B +B = 20[/tex]
⇒[tex]12 - 2B = 20[/tex]
⇒[tex]-2B = 8[/tex]
⇒[tex]B = -4[/tex]
So, [tex]A = 4-(-4) = 8[/tex]
Substitute the value of A and B in the given partial fraction.
⇒[tex]\frac{4x+40}{(x+2)(x+6)} =\frac{8}{(x+2)}-\frac{4}{(x+6)}[/tex]
Hence, the decomposition of the given partial fraction in terms of x is [tex]\frac{4x+40}{(x+2)(x+6)} =\frac{8}{(x+2)}-\frac{4}{(x+6)}[/tex].

Annabelle read 10 books in 2 months. What was her rate of reading, in books per month?
Answer:
5 books per month
Step-by-step explanation:
We are trying to find a rate.
To find books per month, we would take the number of books and divide it by the number of months.
This would give us 10 books/2 months.
10/2 simplifies to 5.
Therefore the answer would be 5 books per month.

A ball is thrown into the air with an initial velocity of 64 feet per second from a height of 336 feet. After how many seconds will the ball return to the ground and have a height of zero again
Answer:
7 seconds
Step-by-step explanation:
Ballistic motion is usually modeled in the vertical direction in US customary units by the equation h(t) = -16t^2 +v0·t +h0, where v0 and h0 are the initial velocity and height, and h(t) is the height as a function of time in seconds. For the given initial conditions, the equation of vertical motion will be ...
h(t) = -16t^2 +64t +336
__
This question asks you for the value of t for which h(t) = 0. We can solve that equation by factoring.
0 = -16t^2 +64t +336
0 = t^2 -4t -21 . . . . . . . . divide by -16
0 = (t -7)(t +3) . . . . . . . factor the quadratic
t = 7 . . . . . . the positive value of t that makes the equation true
The ball will return to the ground after 7 seconds.
__
Additional comment
A graph of the function reveals the ball reaches a maximum height of 400 feet after 2 seconds.
In metric units, the equation is h(t) = -4.9t^2 +v0·t +h0, where distances are in meters instead of feet. Time is still in seconds.
One box measures 2 feet by 1 foot by 1 foot a larger box measures 2feet by 2 1/2 feet by 2 how many times larger is the volume of the larger box then the smaller box
The number of times the larger box is bigger than the smaller box is 5.
How many times larger is the larger box?The first step is to determine the volume of both boxes.
Volume = length x width x height
Volume of the larger box = 2 x 2 1/2 x 2 = 10ft³
Volume of the smaller box = 2 x 1 x 1 = 2 ft³
Now divide the Volume of the larger box by the volume of the smaller box : 10 / 2 = 5

it is from 0 to 1
integral from 0 to 1 of (1 - x) dx
integral 1 dx - integral x dx
integral 1 dx = x
integral x dx = x²/2 by power rule
so the final integral is x - (x²/2)

1 - (1²/2) - 0 - (0²/2)
1 - (1²/2) = 0.5
0 - (0²/2) = 0
