If the original parabola f(x) = x2 were transformed into f(x) = 4(x - 3)2 +1, what changes took place?
А
The parabola would be vertically stretched by a factor of 4, translated right 3 and up 1.
B
The parabola would be vertically compressed by a factor of 4, translated right 3 and down 1.
С
The parabola would be vertically stretched by a factor of 4, translated left 3 and up 1.
D
The parabola would be vertically compressed by a factor of 3, translated left 3 and down 1.
Answer:
A
Step-by-step explanation:
The triangle below is reflected over the line x = 4.
Which transformation(s) would produce the same image?
2676$10
A Reflecting over the x-axis and then translating to the right 4 units
B. Reflecting over the y-axis and then translating to the right 4 units
C Reflecting over the y-axis and then translating to the right 8 units
D Reflecting over the x-axis and then translating to the right 8 units
9514 1404 393
Answer:
C. Reflecting over the y-axis and then translating to the right 8 units
Step-by-step explanation:
Reflection over the line x=4 gives you the transformation ...
(x, y) ⇒ (2·4 -x, y) = (-x +8, y)
This is precisely the same transformation you get by reflection over the y-axis:
(x, y) ⇒ (-x, y)
followed by translation to the right 8 units:
(-x, y) ⇒ (-x +8, y)
__
Reflection over x=4 is the same as reflection over y and translation right 8.

At a dinner, the meal cost $32.00 and a sales tax of $2.40 was added to
the bill.
a. How much would the sales tax be on a $66.00 meal?
b. What is the tax rate for meals at this restaurant?

Answer:
a.70.95
b. 7.5
Step-by-step explanation
If you divide 2.40 by 32, you get the ratio of the tip to cost, which is 0.075, or 7.5 percent. Multiply 66 by 1.075, which includes both the cost and the tax.

Can anyone help I do t know how to find all seven angles
Answer:
1. 110
2. 70
3. 70
4. 110
5. 110
6. 70
7. 70
Step-by-step explanation:
when to lines cross, opposite angles are equal so like 1 and 4 are equal
1, 4, and 5 are equal to 110
to find 2, 3, 6, and 7, subtract 110 from 180
Step-by-step explanation:
110 is vertical from angle 5 so they are the same
180-110=70 degrees
Solve the system of linear equations by ellmination. 5x + 9y = -11 3x + 9y = -3 A. (-4,-1) -B. (-1, –4) C. (-4,1) D. (1,-4)
Answer:
Step-by-step explanation:
5x + 9y = -11
3x + 9y = -3
5x + 9y = -11
-3x - 9y = 3
2x = -8
x = -4
-12 + 9y = -3
9y = 9
y = 1

Answer is C
n electric vehicle has a battery pack that is made up of 10 individual cells. With a 95% probability, we know that any given cell will last at for least 10,000 charge-discharge cycles. Assuming that the failure of any given cell in the battery pack does not depend, in any way, on the performance of any other cell in the battery pack, what is the probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles
Answer:
0.5987 = 59.87% probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles
Step-by-step explanation:
For each cell, there are only two possible outcomes. Either it will least for at least 10,000 charge-discharge cycles, or it will not. Cells are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
10 individual cells.
This means that [tex]n = 10[/tex]
95% probability
This means that [tex]p = 0.95[/tex]
What is the probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles
This is P(X = 10).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 10) = C_{10,10}.(0.95)^{10}.(0.05)^{0} = 0.5987[/tex]
0.5987 = 59.87% probability that every cell in the battery pack will last for at least 10,000 charge-discharge cycles
solve similar triangles advanced Pleasee help! TIA
Answer:
[tex]x = 3.5[/tex]
Step-by-step explanation:
Given
Attached Triangle
Required
Find x
To solve for x, we make use of the following equivalent ratios:
[tex]CB : BA = ED : DA[/tex]
Where:
[tex]CB = 2[/tex]
[tex]BA = 4[/tex]
[tex]ED = x[/tex]
[tex]DA = 3 + 4 = 7[/tex]
So, the expression becomes:
[tex]CB : BA = ED : DA[/tex]
[tex]2 : 4 = x : 7[/tex]
Express as fraction
[tex]\frac{2 }{ 4} = \frac{x }{ 7}[/tex]
Multiply both sides by 7
[tex]7*\frac{2 }{ 4} = \frac{x }{ 7}*7[/tex]
[tex]7*\frac{2 }{ 4} = x[/tex]
[tex]\frac{7*2 }{ 4} = x[/tex]
[tex]\frac{14}{4} = x[/tex]
[tex]3.5 = x[/tex]
[tex]x = 3.5[/tex]

what is 246 : 7 in long division
Here we will show you step-by-step with detailed explanation how to calculate 246 divided by 7 using long division.
Before you continue, note that in the problem 246 divided by 7, the numbers are defined as follows:
246 = dividend
7 = divisor
Step 1:
Start by setting it up with the divisor 7 on the left side and the dividend 246 on the right side like this:
7 ⟌ 2 4 6
Step 2:
The divisor (7) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
7 ⟌ 2 4 6
Step 3:
Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.
0
7 ⟌ 2 4 6
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
7 ⟌ 2 4 6
- 0
2
Step 5:
Move down the 2nd digit of the dividend (4) like this:
0
7 ⟌ 2 4 6
- 0
2 4
Step 6:
The divisor (7) goes into the bottom number (24), 3 time(s). Therefore, put 3 on top:
0 3
7 ⟌ 2 4 6
- 0
2 4
Step 7:
Multiply the divisor by the result in the previous step (7 x 3 = 21) and write that answer at the bottom:
0 3
7 ⟌ 2 4 6
- 0
2 4
2 1
Step 8:
Subtract the result in the previous step from the number written above it. (24 - 21 = 3) and write the answer at the bottom.
0 3
7 ⟌ 2 4 6
- 0
2 4
- 2 1
3
Step 9:
Move down the last digit of the dividend (6) like this:
0 3
7 ⟌ 2 4 6
- 0
2 4
- 2 1
3 6
Step 10:
The divisor (7) goes into the bottom number (36), 5 time(s). Therefore put 5 on top:
0 3 5
7 ⟌ 2 4 6
- 0
2 4
- 2 1
3 6
Step 11:
Multiply the divisor by the result in the previous step (7 x 5 = 35) and write the answer at the bottom:
0 3 5
7 ⟌ 2 4 6
- 0
2 4
- 2 1
3 6
3 5
Step 12:
Subtract the result in the previous step from the number written above it. (36 - 35 = 1) and write the answer at the bottom.
0 3 5
7 ⟌ 2 4 6
- 0
2 4
- 2 1
3 6
- 3 5
1
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 246 divided by 7 calculated using Long Division is:
35
1 Remainder
