Answer: All real numbers greater than or less than 9.
Step-by-step explanation: The range is possible y-values. In a parabola the range starts at a particular place then it either goes up or goes down. Since the leading factor has a negative in front of it, the parabola will open downward meaning most likely all y-values will be lest than the include max point. Now let find the max point using the formula -b/2a then substituting that into the parabola. -2/2(-1)= 1, then plug it in. y=-(1^2)+2(1)+8 which equal -1+2+8 which equal 9 so the max point is 9. Since the graph open downward all the points that are possible will either be at 9 or below it so the range is All real numbers greater than or less than 9. or (-∞,∞)∪(∞,9]

A fox, a coyote, and a wolf weigh a total of 120 pounds. The ratio of the weight of the fox to the weight of the coyote is 3:8. The weight of the coyote is 32 pounds. What is the weight of the wolf?
PLEASE HELP I WILL REWARD BRAINLIEST
Answer:
so you divide 32 by 8 which gets you to 4. then you multiply 4 by 3 to get 12. The weight of the form is 12 pounds. you then subtract 44 (the weight of the fox and coyote combined) from 120. which leaves you at 76. si the weight of the wolf is 76 pounds (the ratio is 3:8:19 because 76 divided by 4 is 19)
Step-by-step explanation:

Answer:
52 square units
Step-by-step explanation:
Drop a perpendicular from the top left vertex to the bottom base creating a right triangle. You have a 30-60-90 right triangle with the ratio of the lengths of the sides being 1 : sqrt(3) : 2
Then, the height of the trapezoid is the triangle's opposite leg to the 60-deg angle.
The triangle's adjacent leg to the 60-deg angle is half the hypotenuse, or 3 units.
The height is sqrt(3) times the adjacent leg.
The base of the trapezoid has length 3 + 7 + 3 = 13
A = (b1 + b2)h/2
A = (13 + 7)(3sqrt(3))/2

5. Jennifer's school is selling tickets to the annual dance
competition. On the first day of ticket sales the school sold 2 senior
citizen tickets and 7 student tickets for a total of $40. On the second
day by selling 8 senior citizen tickets and 2 student tickets for a total
of $56.
a.
Define variables:
b. System:
C.
Solve the systems (optional):
Step-by-step explanation:
Let "x" be the number of senior tickets and "y" be the number of student tickets.
1st day: 2x + 7y = 40
2nd day: 8x + 2y = 56
(I am going to solve this by elimination and using addition because I find that easier.)
First, we are going to get rid of "y":
2 (2x + 7y = 40) -7 (8x + 2y = 56)
= 4x + 14y = 80 = -56x - 14y = -392
( We multiply the second equation by "-7" so that we can cancel "y")
Now add the equations:
4x + 14y = 80
-56x - 14y = -392
= - 52x = -312
Now divide -312 by -52
= x = 6
Now subsitute 6 in for "x" in the first equation:
2(6) + 7y = 40
= 12 + 7y = 40
Subtract 12 from each side:
= 7y = 28
Divide 7 from each side:
= y = 4
Answer:
x = 6
y = 4

-7.375
-0.27(27 goes on forever)

Step-by-step explanation:
this is really easy, a fraction is really when broken down, is just a simple division problem, we will take the second problem as an example;
-7 3/8
to solve for the fraction, we can look at it as a problem itself
-7 ( 3 / 8 )
solve said division problem
3 / 8 = 0.375
and add whatever whole numbers you have to this, theres no need to change any proportional relationships between any of the numbers
-7.375

Raymond works in an electronics store and gets a 12 percent employee discount. The original cost of a video game system is $175. What is the discounted price of the game system?
$154.00
$163.00
$187.00
$196.00
Answer:
A. $154.00
Step-by-Step Explanation:
Okay so, the first step is to get 12% and move the decimal to the left twice like this:
.12
Then, multiply 175 by .12 like this:
175 * .12 = 21
Lastly, subtract 21 from 175 like this:
175 - 21 = $154

Is it possible to construct a sector such that the length of the radius is equal to the length of the arc created by its central angle?
Explain why or why not, and include the radius lengths and central angle measures that you tried.
Answer:
No
A 30 degree central angle would be a 30 degree arc.
The sin of 30 degrees is 0.5 so the arc would be just greater than 15, much less than 30.

sin∠C/7=sin90/[tex]\sqrt{74}[/tex]
∠C=54.462
9514 1404 393
Answer:
E. 54.462
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship involving the adjacent side and the hypotenuse:
Cos = Adjacent/Hypotenuse
cos(C) = CB/CA = 5/√74
Then the angle is found using the inverse function:
C = arccos(5/√74) ≈ arccos(0.581238)
C ≈ 54.462°
The measure in degrees of angle C is about 54.462.
