A rectangular building with a square base is being designed to minimize heat loss. The building designers state that the volume of the building must be exactly 4000 m^3. Write an equation for y, the height of the building, in terms of x, the length and width of the base.
Answer:
y = 4000/x²
Step-by-step explanation:
The volume of the building is expressed as;
V = x²y where;
x is the length and width of the base.
y is the height of the building
Given
Volume V = 4000m³
Substitute the given volume into the equation as shown;
4000 = x²y
Make y the subject of the formula by dividing both sides by x²
4000/x² = x²y/x²
4000/x² = y
Rearrange
y = 4000/x²
Hence equation for y, the height of the building, in terms of x, the length and width of the base is expressed as y = 4000/x²

F(x)=43
f(x)=-6×+7
Not sure how to get the answer wondering if someone can break it down for me please
Step-by-step explanation:
Since f(x) is 43 you would replace it for the f(x) in the bottom equation like this 43=-6×+7 then you would multiply the left side so now it would be 43=-42 and this a no solution.

112p^2 -224p + 4
Step-by-step explanation:
16(p-2)(7p) + 4
Distributive property.
Use Foil
Multiply the: First, outside, inside, last
112p^2 -224p + 4
Answer:
112p^2 - 160p -128
Step-by-step explanation:
1) Look at the equation as a multiplication of 3 parts:
16 * ( p -2) * (7p + 4)
2) Multiply 16 with (p-2) = 16p - 32
3) Multiply 16p - 32 with (7p + 4) = 112p^2 + 64p - 224p - 128
4) Simplify: 112p^2 - 160p -128

What’s quadratic equation
Answer:
In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax^2+bx+c-0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a .0, then the equation is linear, not quadratic, as there is no ax^2 term. The numbers a, b, and c are the coefficients of the equation and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.
Step-by-step explanation:
Good Question I just had a class about it 10 minutes ago such a coincidence! :)

The cost of mailing a first-class letter is $0.46 for the first ounce and $0.20 for each additional ounce or portion of an ounce. Y is the total cost for mailing a letter that weighs x ounces. What is the cost of mailing a first class letter weighing 2.5 ounces based on the guidelines given in the previous problem?
Answer:linear function
Step-by-step explanation:
The cost of mailing a first class letter weighing 2.5 ounces is $0.96,
What are linear equation?A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now given that,
cost of mailing a first-class letter for the first ounce = $0.46
cost of additional ounce or portion of an ounce = $0.20
Since,the weight of letter is x ounces
cost of mailing a first-class letter = $0.2x
Now,Y is the total cost for mailing a letter
Y = 0.46 + 0.2x
Therefore, the cost of mailing a first class letter weighing 2.5 ounces
Y = 0.46 + 0.2*2.5
⇒ Y = 0.46 + 0.5
Y = $0.96
Thus,The cost of mailing a first class letter weighing 2.5 ounces is $0.96

Answer:
m∠ABC = 81°
m∠FEC = 90°
Step-by-step explanation:
The median BE of isosceles triangle ABC is also an altitude and the angle bisector of ∠ABC. This means ...
m∠ABC = 2×m∠ABE = 2(40°30')
m∠ABC = 81°
It also means that all of the angles at the intersection of BF and AC are right angles, so ...
m∠FEC = 90°
