Find the values of x and y that make the quadrilateral a parallelogram.
4x + 6
4y - 3
By + 1
7x - 3

Answer:

x > 49

Step-by-step explanation:

We have the inequality Square root of x is greater than 7, to solve. We need to isolate x.

When having a square root, you need to raise the square root to its second power, with that, do the same to 7 on the other sides :

(Square root of x)^2 > 7^2

x > 49

Answer:

330cm²

Step-by-step explanation:

CSA of a cylinder = 2πrh

(r = d/2 = 21/2 = 10.5 cm)

Putting the values of 2πrh;

2 x 22/7 x 10.5 x 5

2 x 22 x 1.5 x 5 *(10.5/7 = 1.5)

330 cm²

Answer:

Development costs: $2757

Promotion costs: $3155

Step-by-step explanation:

This might seem like a two-variable problem, but in actuality it's not - because the demand function is a sum of two components, each being independent and using only one variable, we can solve for the two separately.

Moreover, the price per unit and cost per unit is constant, so each product yields exactly $80 ($210 - $130).

Let's solve separately.

We need to maximize:

$80 * 160y/(y+4) - 1000y = $12800 * y/(y+4) - $1000*y

$80 * 170x/(x+7) - 1000x = $13600 * x/(x+7) - $1000*x

Let's go:

$12800 * y/(y+4) - $1000*y = $12800 * (1 - 4/(y+4)) - $1000y = $12800 - $51200/(y+4) - $1000*y

we analyze the derivative. $12800 is a constant, so we can skip it. Derivative of 1/(y+4) is -(y+4)^-2, derivative of $1000y is $1000.

deriv = $51200/(y+4)/(y+4) - $1000

We find the changepoints by analyzing $51200/(y+4)/(y+4) - $1000 = $0. We don't need to worry about y+4 = 0 because we cannot spend negative money on development/advertisement.

(y+4)^2 = $51.2

y+4 ~= 7.155417528 (or -y-4 = 7.1554... but it doesn't make sense because negative budget so we don't analyze).

y ~= 3.155417528

lastly, we should check that it's actually a maximum there - but it is, the original function goes to negative infinity.

rounding $1000y to the nearest dollar gives us $3155

Let's do the same for x:

$13600 * x/(x+7) - $1000*x = $13600 * (1 - 7/(x+7)) - $1000x = $13600 - $95200/(x+7) - $1000*x

deriv = $95200/(x+7)/(x+7) - $1000

$95200/(x+7)/(x+7) - $1000 = $0

(x+7)^2 = 95.2

(x+7) ~= 9.75704873412

x ~= 2.75704...

rounding $1000x to the nearest dollar yields $2757

Using the formula of area of a square, the fewest number of tiles required will be approximately 3

A square can be defined as a closed two-dimensional shape with four sides that are equal to each other and four equal angles. The four sides of the square will form the four angles at the vertices. The sum of the length of all the sides of a square is known as the perimeter, and the total space occupied by the shape is the area of the square.

The formula of area of a square is given as

A = l²

The total area of the floor can be calculated as

A = l²

A = 5²

A = 25 ft²

The least number of tiles required to cover the floor will be calculated using the square with it's largest side

l = 3ft

A = 3²

A = 9ft²

The numbers required will be 25 / 9 = 2.78≅3

Let the students with B(s) be x.

So, the students with C should 10 more than x = x + 10

Total students = 50

=> students with B + students with C = 50

=> x + (x + 10) = 50

=> 2x + 10 = 50

=> 2x = 50 - 10 = 40

=> x = 40/2 = 20

Thus,

students with B = x = 20

students with C = x + 10 = 20+10= 30

Number of students who had a B are 20.

And, Number of students who had a C are 30.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

There are 50 students who had grades of B or C.

There were 10 more students with C’s than B’s.

Now,

Let number of students who had grade B = x

So, The number of students who had grade C = x + 10

So, we can formulate;

x + (x + 10) = 50

x + x + 10 = 50

2x + 10 = 50

2x = 50 - 10

2x = 40

x = 20

Thus, The number of students who had grade B = x

                                                                          = 20

So, The number of students who had grade C = x + 10

                                                                       = 20 + 10

                                                                       = 30

Therefore, Number of students who had a B are 20.

And, Number of students who had a C are 30.

Answer:

f−1(x) = [tex]\frac{4x}{6}[/tex]

Step-by-step explanation:

f(x) = 0.25(6)x, find f−1(x).

f(x) = 0.25(6)x

f(x) = [tex]\frac{6}{4}[/tex]x = [tex]\frac{6x}{4}[/tex]

f(x) = y

y =  [tex]\frac{6x}{4}[/tex]

Substitute y for an x & x for a y

x = [tex]\frac{6y}{4}[/tex]

Multiply both sides by 4

4( x ) = 4( [tex]\frac{6y}{4}[/tex] )

4x = 6y

Divide both sides by 6 to solve for y

[tex]\frac{4x}{6}[/tex] = y

y = [tex]\frac{4x}{6}[/tex]

so f−1(x) = [tex]\frac{4x}{6}[/tex]
