Answer 2

The expression showing the number of students in the drama club the next year is 15+d.

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, there are 20 students in a drama club,

5 of them will leave in next year, and d students will join,

We are asked to construct an expression to represent the total number of students in the drama club next year.

So, the present number of students in the club = 20

After next year = 20-5 = 15

After the joining = 15+d

Hence the expression showing the number of students in the drama club the next year is 15+d.

A square has an area of 12x^2 square feet. What is the length of its sides?

Answers

The area of a rectangle is found by multiplying the length by the width or L*W.
In a square the length and width are the same so just call the value
s for each side.

l*w = s*s = s2

In this case we have
s2 = 12x2 Take square root of both sides
s = √(12x2)
s = x√12
s = x√(4*3)
s = x√(22*3)
s = 2x√3

If you want the variable at the end of the number
you can write this as (2√3)x
I only put the parentheses to denote that the
term x is not part of the square root.

6. The total cost of materials to build the foam
pit is $1,285.20. What is the cost of materials
per square foot?

Answers

Answer:

Cost of Material per square foot = $1.7

Step-by-step explanation:

Given:

Length = 24

Width = 12

Height = 6.5

Find:

Cost of Material per square foot

Computation:

TSA of pit = 2[bh + hl] + lb

TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)

TSA of pit = 2[78+156] + 288

TSA of pit = 756 square foot

Cost of Material per square foot = 1,285.20 / 756

Cost of Material per square foot = $1.7

Answer:

432 inches.

Step-by-step explanation:

The formula for finding the area of a triangle is;

[tex]\frac{b*h}{2}[/tex]

Using this, we can find the area of each individual piece.

[tex]\frac{6*6}{2} =18[/tex]

Now that we have this, we simply multiply 18 by 24, which gives us 432.

Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16.

Answers

Answer:

See solutions below

Explanation

We are to find the equation of circle A and B

The equation of a circle is expressed as;

(x-a)^2 + (y-b)^2 = r^2

(a, b) is the centre and r is the radius

For Circle A that has center of (6, 7), and a radius of 4

Substitute;

(x-6)^2 + (y-7)^2 = 4^2

(x-6)^2+(y-7)^2 = 16

Hence the equation of circle A is (x-6)^2+(y-7)^2 = 16

For circle B:

If circle B has a center of (2, 4), and a radius of 16

The equation is expressed as;

(x-2)^2+(x-4)^2 = 16^2

(x-2)^2+(x-4)^2 = 256

Hence the required equation is (x-2)^2+(x-4)^2 = 256

Use the information given to enter an equation in standard form.

(9, 10) and (8, 7) are on the line.

Answers

Answer:

The equation in the standard form of the line through the given points is;

y = 3x - 17

Step-by-step explanation:

We start by getting the slope of the line;

m = (y2-y1)/(x2-x1)

m = (7-10)/(8-9) = -3/-1 = 3

The stands equation form is;

y = mx + b

m is slope, b is the y-intercept

so we have

y = 3x + b

To get b, we substitute the coordinates of any of the points

10 = 3(9) + b

10 = 27 + b

b = 10-27

b = -17

So the equation is;

y = 3x - 17

Answers

Answer:

8) x=9

10) 23 degrees

Step-by-step explanation:

8) vertical angles are congruent to each other so we can set the expressions as such and solve:

7x + 3 = 10x - 24

3 = 3x - 24

27 = 3x

9 = x

10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for x:

12x + 7 + 6x - 7 = 90

18x + 7 - 7 = 90

18x = 90

x = 5

now we plug it back into the expression equivalent to the measure of angle O:

6(5) -7

30 - 7

I need to find the AREA of these 6 circles using 3.14.

Step-by-step explanation:

Step-by-step explanation:

In order to find each one, you use the formula A=pi R², meaning you put the radius to the power of two(multiply it by itself) and then multiply that by pi. ex: 7.4×7.4= 54.76,

next 54.76×3.14=171.9, which is your answer. If it gives you the diameter of the circle, divide that by two to get the radius, and follow the steps from before. Ex: 2.24÷2=1.12, next 1.12×1.12=1.2544, next 1.2544×3.14=3.9, the answer.

Based on the end behaviors, which graph is the graph of f(x) = -2x4 − 4x3 + x2 + x + 3?

Answers

Given:

The function is

[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]

To find:

The graph of the function by using the end behaviors.

Solution:

We have,

[tex]f(x)=-2x^4-4x^3+x^2+x+3[/tex]

The degree of the polynomial is 4 which is even and the leading coefficient is -2, which is negative. So,

[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]

[tex]f(x)\to -\infty\text{ as }x\to \infty[/tex]

It means, the graph of the function approaches to negative infinity on the both ends.
