y = x ^2 /8
Vertex: ( 0 , 0 ) Focus: ( 0 , 2 ) Axis of Symmetry: x = 0 Directrix: y = − 2
Evaluate the function rule for the given value. Y=12×3^x for x=-2
Answer:
Y = 4/3
Step-by-step explanation:
Solve for Y:
3 Y = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 Y = 4 by 3:
(3 Y)/3 = 4/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
Answer: Y = 4/3

6n + 12 = -60 - 35
Answer:
6n + 12 = -60 - 35
-12 -12
6n = -107
Divide by 6 on both sides:
N = -17.8333333333 around -17
Step-by-step explanation:
We need to isolate the variable meaning keeping the variable by itself on the left side. In order to do that we must get rid of any constants or co-efficients.
Answer:
Hey mate......
Step-by-step explanation:
This is ur answer.....
6n + 12 = -60 -35= 6n + 12 = -95
= 6n = -95 - 12
= 6n = -107
= n = -107 / 6
= n = 17.83

99 is the largest number
62 is the smallest number
99-62
37
The range is the difference between the largest number and the smallest number.
Largest number is 99
Smallest number is 62
Range = 99-62 = 37
The answer is C) 37
Find the length of the third side. 20 24
Answer:
Hypotenuse (Third side) = 31.24
Step-by-step explanation:
20² + 24² = Hypotenuse²
400 + 576 = Hypotenuse²
976 = Hypotenuse²
[tex]\sqrt{976}[/tex] = Hypotenuse
31.24 = Hypotenuse
Therefore, the measure of the third side would be: 31.24

I am very confused on this question
A bag contains 4 yellow, 2 red, and 6 green marbles. two marbles are drawn. the first is replaced before the second is drawn. a random variable assigns the number of red marbles to each outcome. calculate the expected value of the random variable.
a. 0.67
c. 0.17
b. 0.56
d. 0.33
Answer:
c. 0.17
Step-by-step explanation:
The bag have 4 + 2 + 6 = 12 balls.
There are 2 red marbles, in 12, the probability to take one red is 2/12. Is important to remember that the first marble was replaced before the second outcome, so the chance for the second is also 2/12:
2/12 = 1/6 = 0.1666 ≈ 0.17
The expected value of the random variable that assigns the number of red marbles to each outcome is 0.17.
What is the probability?Probability is used to estimate how likely an event would happen. The probability the event occurs with certainty is 1 and the probability that the event does not occur with certainty is 0.
Expected value = number of red marbles / total number of marbles
2/12 = 0.17

Find the cosine of ∠G (Must give explanation)
also why does my calculator say its undefined if I do the cos invert of (85/77) ??
cos^-1(85/77) = undefined ?? why
Answer:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
Step-by-step explanation:
Recall that cosine is the ratio of the adjacent side to the hypotenuse:
[tex]\displaystyle \cos(G)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]
The hypotenuse is always the side opposite to the right angle. In this case, it is
85.
The adjacent side to G is 36.
Therefore:
[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]
For your other question, remember that in a right triangle, cosine is the ratio of the adjacent side to the hypotenuse.
As you know, the hypotenuse is always the longest side in a right triangle.
Therefore, the ratio of the adjacent side to the hypotenuse will never be greater than 1.
Since 85/77 is greater than 1, it is undefined.
The same applies to sine as well.

Tucker's Road Paving Company used 646.5 tons of cement to pave 4 miles of roadway. To the nearest hundredth of a ton, how much cement, on average, did the company use per mile?
Answer:
161.63 tons
Step-by-step explanation:
Cement used per mile = total cement used / total miles
646.5 tons / 4 = 161.625 tons
161.63 tons to the nearest hundredth
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
the thousandth term is 5, so 1 would be added to 2

Answer:29
Step-by-step explanation:
Opposite angles in a quadrilateral (the trapezium inside the circle) must add up to 180, so 180-92 = 88.
So DAB = 88
Angles on a straight line add up to 180, so to find t, you have to 180 - 88 - 63 = 29
So t is 29.

Solve the system by substitution.
3x + 1 = y
10x – 4y = -8
Pls help
Answer:
x = 2
y = 7
Step-by-step explanation:
3x + 1 = y
10x - 4y = -8
10(2) - 4(7) = -8
20 - 28 = -8
-8 = -8
3(2) + 1 = (7)
6 + 1 = 7
7 = 7
Answer: x = 2, y = 7, (2,7) are coordinates
Step-by-step explanation:
So your going to replace "y" in the second equation, for the value of "y" described in the first.
10x-4(3x+1)= -8
10x-12x-4 = -8
10x-12x = -4
-2x = -4
x = 2
Now we solve for "y" by substituting with the value of "x" we just found. So it's...
3(2) + 1 = y
6+1=y
y = 7
The coordinates are (2,7)

Corresponding parts of similar triangles are proportionate
Consider the figure below, where line a is parallel to line b:
Angle 4 = 12m - 4
Angle 5 = 10m + 20
Calculate the measure of Angle 5.
Answer:
Angle 5= 140
Step-by-step explanation:
I assume you are talking about parrallel lines and a transversal. If that is the case, I can guess that angles 4 and 5 are alternate exterior angles. Therefore they are congruent.
12m-4=10m+2012m=10m+24 You add 4 to -4 and 202m=24 You subtract 10m from 10m and 12mm=12 Divide both sides by 210(12)+20 Substitute m for 12 in the equation for Angle 5120+20 Multiply 10 by 12140 Add 120 and 20
Simplify the following expression as much as possible.
