Domain: (-∞, ∞)
Range: (-∞,1]
Answer:
Domain = All Real Numbers
Range = y≤1
Step-by-step explanation:
Since parabolas are continuous, the domain is all real numbers. The range, or y value, is all real numbers less than or equal to 1 (y≤1), since 1 is the vertex.
Hope this helps :)

Wer +266. A bag contains $3$ balls labeled $2, 4$ and $8$. A ball is to be picked, the value on the label is to be recorded and then the ball is to be returned to the bag. This will be done three times and then the values will be added together. What is the sum of all of the possible distinct sums?
Answer:
The sum of all the possible distinct sum is 128
Step-by-step explanation:
The number of balls in the bag = 3
The ball labels, (the numbers written on the balls) = 2, 4, and 8
The number of balls selected with replacement = 1
Therefore, we have have, the number of ways of selecting 1 ball from 3 = 3 ways
The distinct combination of the selected balls are;
2, 2, 2 with sum 2 + 2 + 2 = 6
2, 2, 4 with sum 2 + 2 + 4 = 8
2, 2, 8 with sum 2 + 2 + 8 = 12
2, 4, 4 with sum 2 + 4 + 4 = 10
2, 4, 8 with sum 2 + 4 + 8 = 14
2, 8, 8 with sum 2 + 8 + 8 = 18
4, 4, 4 with sum 4 + 4 + 4 = 12
4, 4, 8 with sum 4 + 4 + 8 = 16
8, 8, 4 with sum 8 + 8 + 4 = 20
8, 8. 8 with sum 8 + 8 + 8 = 24
The distinct sums are therefore;
6, 8, 12, 10, 14, 18, 16, 20, 24
The sum of the distinct sum is 6 + 8 + 12 + 10 + 14 + 18 + 16 + 20 + 24 = 128.
Answer: 128
Step-by-step explanation:
Any sum formed by a combination of the numbers 2, 4, 8 and must be divisible by 2. The smallest possible value of such a sum is equal to 3*2=6 , and the largest possible value of such a sum is equal to 3*8=24 . After testing, we find that
6 = 2+2+2, 8=4+2+2, 10=4+4+2
12 = 4+4+4, 14 = 8+4+2, 16 = 8+4+4
18 = 8+8+2, 20 = 8+8+4, 24 = 8+8+8
However, we cannot find a combination that will add to be 22: if two of the numbers are not 8, then the maximum possible sum is 4+4+8 = 16. Thus, two of the numbers picked must be 8, but then the third ball must have the number 6, which is not possible. Thus, the answer is the sum of the even numbers from 6 to 24 excluding 22, which is 128 .
Which expression is equivalent to the following?
(5×10−3)+(6×10−3)2.2×104
A.5 × 10-7
B.5 × 10-1
C.5 × 10-10
D.5 × 107
Answer:
1.32 * 10^2
Step-by-step explanation:
Given the expression;
(5×10−3)+(6×10−3)2.2×10^4
First we need to do the multiplication first;
= (5×10−3)+(13.2×10−3+4)
= (5×10−3)+(13.2×10^1)
= 0.005 + 132
= 132.005
= 1.32 * 10^2
Hence the equivalent expression is 1.32.0 * 10^2

If you have $22 right now and $40 in the bank what % is the part you have from you total %62.
Answer:
35% on you
Step-by-step explanation:
22/62
Answer:
35.48% or 35.5% rounded
Step-by-step explanation:
So, let me just list the givens:
- You have $22 right now
- You have $40 in the bank
- You have a total of $62.
This is what we need to find:
- What percent is 22 of 62?
In order to get the what percent 22 is of 62, we need to divide 22 by 62.
[tex]\frac{22}{62} = .3548[/tex]
To change this to a percent we would move the decimal 2 times to the right so it will look like this:
.3548 --> 35.48%
Therefore, 20 is 35.48% of the total
I hope this is what you were asking for, if not let me know.

Lena and 3 of her friends bought just enough food to go on a 12- day camping trip. Pete and Jane surprised them by showing up at the start of the trip and asking to join, but they brought no food. By what percent would the time for the trip shorten for the trip if everyone ate their normal portions?
The number of people increased by 2.
This means as a ratio it is now 6/4 as many as originally planned.
6/4 can be reduced to 3/2.
The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.
This means the length of time the food lasts is reduced by 1/3, which is 33.3%
I NEED HELP!!! What is is this ----> 3x - 3y = 3 12x + 8y = -8
x = what
y = what
Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6

How to find the angle of a right triangle?A right angle triangle has one of its angles as 90 degrees.
The sum of angle in a triangle is 180 degrees.
Therefore,
x + 90 + 23 = 180
x + 113 = 180
x + 113 - 113 = 180 - 113

Answer:
A) 2.8 m
Step-by-step explanation:
The formula for the volume of a right rectangular prism is:
Volume = Length × breadth × height
We can just put in the values that we know to find the height.
110.1 = 7.8 × 5.1 × height
height = 110.1 ÷ 7.8 ÷ 5.1
height ≈ 2.8 (rounded to nearest tenth)
