Answer:
4x²+6x-40
2(2x²+3x-20) factor out 2
2(2x²+8x-5x-20) split the three into a difference
2(2x(x+4)-5x-20) factor the 2 out of first pair of parenthesis
2(2x(x+4)-5(x+4)) factor the 5 out of second pair of parenthesis
2(x+4)(2x-5) factor
= 2(x+4)(2x-5)

You are the owner of the biggest and newest roller coaster called the Gentle Giant. The roller coaster costs $6 to ride. The operator of the ride must pay $200 per day for the ride rental and $65 per day for a safety inspection. If you want to make a profit of at least $1,000 each day, what is the minimum number of people that must ride the roller coaster? Write an inequality that can be used to find the minimum number of people, , which must ride the roller coaster each day to make the daily profit.
Answer:
Inequality: 6r - 200 - 65 [tex]\geq[/tex] 1000 and minimum of 211 people
Step-by-step explanation:
Let r = rides
6r - 200 - 65 [tex]\geq[/tex] 1000
6r - 265 [tex]\geq[/tex] 1000
6r [tex]\geq[/tex] 1265
r [tex]\geq[/tex] 210 [tex]\frac{5}{6}[/tex]
Needs 211 people to make a profit of at least $1000

What are the answers to these?
What is the measure of angle B in degrees?
Answer:
<B=119
Step-by-step explanation:
Each line of the triangle is straight, meaning they add up to 180. Additionally, all the angles of the triangle add up to 180. Using that, you can find the measure of each angle.
For <C;
180-112=68
So <C=68
For <A;
180-51-68=61
So <A=61
To make sure that all these angles add up correctly;
51+68+61=180
For <B;
180-61=119
So <B=119

Answer:
A = 4.5
Step-by-step explanation:
Area of a triangle:
A = 1/2bh
Given:
b = 3
h = 3
Work:
A = 1/2bh
A = 1/2(3)(3)
A = 1.5(3)

The total surface area of a cylinder with height 5 in. is given by the function g(x) = 2πx2 + 10πx, where x is the radius, and the function f(x) = 10πx gives the surface area of the side of the cylinder. Which combined function gives the total surface area of the two bases of the cylinder? A. f + g B. f – g C. g – f D. f · g
Answer:
C. g - fStep-by-step explanation:
Total surface area of a cylinder with height 5 is:
A = 2πrh + 2πr² = 10πr + 2πr²If we substitute r with x, we get:
g(x) - full surface areaf(x) - surface areaTotal surface area of two bases:
g - f = 2πx² + 10πx - 10πx = 2πx²Correct choice is C
Solve for the surface area

Answer:
615.75216
Step-by-step explanation:
A=πr2

≈615.75216
Answer:
[tex]r = 14cm \\ area = \pi \: r {}^{2} \\ area = 3.14 \times 14 \times 14 \\ area = 3.14 \times 196 \\{area = 615.44}[/tex]
If the area of a rectangular pool is represented by (12x×x)-17x-5, the length could be represented by ... A.(3x+1) B.(3x+5) C.(4x-5) D.(4x+1)
Answer:
D.(4x+1)
Step-by-step explanation:
The area of the rectangular pool is given by
Area = length * breadth
Area = (12x×x)-17x-5
A= 12x²- 17x- 5
Factorising the quadratic equation by mid term break rule.
A= 12x²- 20x + 3x- 5
( when we multiply 12 and -5 we get -60 . We need two numbers which when added give -17 and when multiplied give -60. The two numbers would be -20 and +3. The minus has to be with the bigger number as we need - 17.)
A = 4x( 3x- 5) + 1( 3x-5)
(taking commons will evaluate it further.)
A= (3x-5) (4x+1)
so the length could either be 3x-5 or 4x+1
From the given options we have
4x+1 as the length because the rest do not match the factors obtained.
