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

L'(6,8)

Step-by-step explanation:

If i had to take a guess what i would is subtract 4 from each x number and add 3 to each y number and then reflect over the line y=4 so then that would give me each distance. And by the looks it seems L'(6,8) is the farthest from he origin (0,0)

Answer:linear function

Step-by-step explanation:

The cost of mailing a first class letter weighing 2.5 ounces is $0.96,

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: His MPH is 40

Step-by-step explanation: 100/2.75 = 40. Converting the fraction to decimal form makes this problem much easier.

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.

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°

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:

Step-by-step explanation:

The value of the given expression 2cos2(105⁰) − 1 is,

⇒ - 1 - √3

A right-angled triangle's angle can be related to side length ratios using trigonometric functions, which are real functions in mathematics. They are extensively used in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many others.

We have to find the value of;

⇒ 2cos2(105⁰) − 1

Now, We can Plug 105° = θ

So, the expression becomes,

⇒ 2cos2θ - 1

Using the formula;

cos2θ = 1 - 2sin^2θ

We get;

⇒ 2cos2θ - 1 = 2(1-2sin^2θ) - 1

                    = 2 - 4sin^2θ - 1

⇒ 2cos2θ - 1 = 1 - 4sin^2θ

Now, Again plug θ = 105°

⇒ 2cos2(105°) - 1  = 1 - 4sin¹⁰⁵

⇒ 2cos2(105°) - 1  = -1 - √3

Hence, The value of the given expression is,

⇒ (-1 - √3)

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

654 over 3 = divide the both 654 and 3 by 3.

It will give you 218 over 1.

So the answer is 218.
