Answer: I Think It Is Greater Than Or Equal To -9
Step-by-step explanation: The given function is:
f(x)x^2+2x-8
We complete the square to write this function in the form:
f(x)=a(x-h)^2+k
We add and subtract the square of half the coefficient of x.
f(x)=x^2+2x+1^2-1^2-8
f(x)=(x=1)^2-9
The vertex of this function is (h,k) which is (-1,-9)
The equation of axis of symmetry is x=h
But h=-1, hence the axis of symmetry isx=-1
To find the x-intercepts, we put f(x)=0
(x+1)^2-9=0
(x+1)^2=9
x+1=the square root of 9
x=-4, 2
The x-intercepts are:(
-4,0) and (2,0)
The given function is a polynomial function, the domain is all real numbers
The function has a minimum value of y=-9.
Therefore the range is y|y is greater that or less than -9

What is -2x=-8-2y in slope intercept form
Answer: y = x - 4
Step-by-step explanation:
Slope intercept form is y = mx + b
Given:
-2x = -8 -2x
Add 2x and 2y to both sides of the equation:
2y = 2x - 8
Divide both sides of the equation by 2:
y = x - 4

x = 5, AB = 14, BC = 8
=====================================================
Explanation:
The triangles are similar, which can be proven through the angle angle theorem.
The similar triangles allow us to form the proportion below.
EB/DB = AB/BC
7/4 = (2x+4)/(x+3)
7(x+3) = 4(2x+4)
7x+21 = 8x+16
21-16 = 8x-7x
5 = x
x = 5 is part of the answer
Then we can use that x value to find the following
AB = 2x+4 = 2*5+4 = 14 is the length of AB
BC = x+3 = 5+3 = 8 is the length of BC

Benito earns $250 per week giving surfing lessons plus $75 for each surfboard he sells. If Benito wants to earn at least $500 this week, which inequality could be solved to find x, the number of surfboards he needs to sell?
Group of answer choices
250 x +75< equal to 500
250 +75x> equal to 500
250+75x equal to 500
Multiply 75 by the number of surfboards sold to get 75x add that to what he makes giving lessons:
250 + 75x
He wants to earn at least 500 so the equation has to be greater than or equal to 500:
Answer: 250 + 75x > equal to 500

Write an equation in standard form of a line that goes through these two points (3, 4) and (5, -5). Please help and explain it because I want to learn how to do this.
Answer:
first find the slope
finding slope
y2-y1/x2-x1
-5-4/5-3
-9/2
then the slope is -9/2 or -4.5
then y=mx+b
y=-4.5x+b
then replace y=-4.5x+b
replace y by 4 and x by 3
4=-4.5times 3 +b
4=-13.5+b
b=17.5
then the equation is y=4.5x+17.5

The sanitation department calculated that last year each city resident produced approximately 1. 643 × 103 pounds of garbage. There are 2. 61 × 105 people living in the city. How much garbage did the city sanitation department collect last year? 4. 2882 pounds 428. 820 pounds 428,820 pounds 428,820,000 pounds.
Answer:
(d) 428,820,000 pounds of garbage
Step-by-step explanation:
Your calculator or spreadsheet can give you the product of two numbers expressed in scientific notation.
(1.643×10^3 lb/resident) × (2.61×10^5 residents) = 4.28823×10^(3+5) lb
≈ 428.82×10^6 lb
= 428,820,000 lb . . . of garbage
A Football Association has teams with 22
players each. Association rules state that
a player must be paid at least $20,000
and that the total of all players' salaries
for each team cannot exceed $600,000.
What is the maximum possible salary, in
dollars, for a single player?
The maximum possible salary for each player is calculated as $27,272.72
Data;
Numbers of Players in each team = 22Minimum allowed salary = $20,000Maximum allowed salary for the team = $600,000Maximum Possible SalaryThe maximum possible salary for a single player in each team can be calculated when we divide the total maximum allowed salary for the team by the total numbers of players. This would put all the players on an even pay or equal pay.
Let the maximum possible allowed salary be represented by x
[tex]x = \frac{60000}{22} \\x= 27,272.72[/tex]
The maximum possible salary for each player is calculated as $27,272.72

Trigonometric function gives the ratio of different sides of a right-angle triangle. The value of Cos(x), if the value of Sin(x) is 0.3 is 0.954.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
As the value of sin(x) is given to us, therefore, we will find the value of x firstly,
[tex]\rm Sin(x)=0.3\\\\x = Sin^{-1}\ 0.3\\\\x = 17.4576[/tex]
Therefore, the value of cos(x) can be written as,
[tex]\rm Cos(x)\\\\= Cos(17.4576)\\\\= 0.9539\approx 0.954[/tex]
We can also use the trigonometric property, therefore,
[tex]\rm (Sin\ x)^2 +(Cos\ x)^2=1\\\\0.3^2 + (Cos\ x)^2 = 1\\\\Cos(x) = \sqrt{1-0.3^2}\\\\Cos(x)=0.954[/tex]
Hence, the value of Cos(x), if the value of Sin(x) is 0.3 is 0.954.

Step-by-step explanation:
A. First, convert 30 minutes to a hour.
[tex] \frac{30 \: mins}{1} \times \frac{1 \: hour}{60 \: mins} = 0.5 \: hours[/tex]
[tex]4 + 0.5 = 4.5 \: hours[/tex]
Now, we can subsitue.
Part A: 1.

[tex]d(t) = 6 + 5.5 \cos( \frac{3\pi}{4} ) [/tex]
Part B:

Find the distance between the two points in simplest radical
form.
(3,0) and (-3, -8)
Answer: 10 units
Step-by-step explanation:
We will use the distance formula and solve. Let (3, 0) be point 1 and (-3, -8) be point 2.
d = [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]
d = [tex]\sqrt{(-3-3)^{2} +(-8-0)^{2} }[/tex]
d = [tex]\sqrt{(-6)^{2} +(-8)^{2} }[/tex]
d = [tex]\sqrt{36 +64}[/tex]
d = [tex]\sqrt{100}[/tex]
d = 10
The distance between the two points given is 10 units.

A business owner purchases supplies for a laundromat and a car wash.
Part A
The owner purchases 6 cases of laundry soap, 8 cases of fabric softener, and 3 cases of bleach for the laundromat. Each case of laundry soap costs $68.45, each case of fabric softener costs $39.71, and each case of bleach costs $52.25.
Which is the best estimate of the total cost, in dollars, of the laundry items?
A. 750.00
B. 830.00
C. 890.00
D. 920.00
Part B
The owner purchases 5 buckets, 10 brushes, 48 towels, and 1 case of air fresheners for the car wash. The total cost of the purchases is $144.08. Each bucket costs $2.89, each brush costs $7.91, and each towel costs $0.36.
What is the cost, in dollars, of the case of air fresheners?
Enter your answer in the box.
Answer:
part a: is c
part b: $33.25
Step-by-step explanation:
PART A: I did 6x68.45=410.70
8x39.71=317.68
3x52.25=156.75
410.7+317.68+156.75=885.13
so the closest thing to it is c
PART B: i did
5x2.89=14.45
10x9.91=79.10
48x0.36=17.28
14.45+79.10+17.28=110.83
144.08-110.83=33.25
so the case of air fresheners was $33.25
