How does graph y=-3(x+1)2 -1 transforms from the parent function y=x^2?
Answers
Given:
The function is:
[tex]y=-3(x+1)^2-1[/tex]
The parent function is:
[tex]y=x^2[/tex]
To find:
The transformation of the given function from the parent function.
Solution:
The transformation of a function is given by:
[tex]g(x)=kf(x+a)+b[/tex] .... (i)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If k<0, then the graph of f(x) is reflected across the x-axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The given function can be written as is:
[tex]g(x)=-3(x+1)^2-1[/tex]
Let the parent function be [tex]f(x)=x^2[/tex], then
[tex]g(x)=-3f(x+1)-1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]k=-3,a=1,b=-1[/tex]
Therefore, the graph of parent function is stretched vertically by by factor 3 and reflected across the x-axis because [tex]k=-3[/tex], after that the graph of the function shifts 1 unit left and 1 unit down to get the graph of given function.

find the length of side xx in simplest radical form with a rational denominator.
Answers
For given right triangle, the length of hypotenuse x = 4/√3
Here we have been given a 30° - 60°- 90° right triangle.
A side opposie to angle 60 degrees measures 2 units.
And x is the hypotenuse of right tirnagle.
To find the value of x, consider sine of angle 60 degrees.
sin(60°) = (opposite side of angle 60°) / hypotenuse
From tirgonometric table, sin(60°) = √3 / 2
So, above equation becomes,
√3/ 2 = 2/x
x = 2 × (2/√3)
x = 4/√3
We can see that the value of x is in in simplest radical form with a rational denominator.
Therefore, x = 4/√3

Answer: 108000
Step-by-step explanation: Here's how I got my answer:
So, first, we need to know something. Whenever there's a fraction, you need to do this. I'll show you the numbers for this problem:
(60^3) / 2
So, the numerator goes in parentheses, and the denominator is what we are dividing by. So, 60^3 is the same as 60 x 60 x 60. You'd get 216000. Then, divide by 2 to get 108000. I hope this helps!

Find the surface area and round to the nearest hundredths place when necessary.

Answer:
First lets find the area of the bottom circle:
7.2 is your radius so:
7.2^2 = 51.84 the reason why you square your radius is because thats apart of the formula when finding the are of a circle.
lets continue:
51.84 x 3.14(pi) = 162.7776
Now we need to find the area of the round surface but first we need to find the circumference of one circle and multiply it by the height.
2 x 3.14 x 7.2 = 45.216
Now lets multiply it by the height:
45.216 x 17 = 768.672
Now lets add both areas:
768.672 + 162.7776 = 931.4496 dont forget to round to the nearest hundredths place! 931.4496 rounded up = 931.45 square meters is your answer.
Jesse is buying a new cell phone online. It costs 8,835.3 yen (Japanese money). The U.S. dollar is worth 88.353 yen. How much will Jesse's cell phone cost in U.S. dollars?
Answers
Answer:
Cost of cell phone in U.S. dollar = 100 U.S. dollar
Step-by-step explanation:
Given:
Cost of cell phone in yen = 8,835.3 yen
1 U.S. dollar = 88.353 yen
Find:
Cost of cell phone in U.S. dollar
Computation:
Cost of cell phone in U.S. dollar = Cost of cell phone in yen[1 / 88.353]
Cost of cell phone in U.S. dollar = 8,835.3[1 / 88.353]
Cost of cell phone in U.S. dollar = 8,835.3 / 88.353
Cost of cell phone in U.S. dollar = 100 U.S. dollar

Answers
Answer:
16.5 inches
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²

A ball bounces to a height of 6.7 feet on the first bounce. Each subsequent bounce reaches a height that is 81% of the previous bounce. What is the height, in feet, of the sixth bounce
Answers
After solving, the height in feet of the sixth bounce is 1.892 feet.
In the given question, we ave to find the height, in feet, of the sixth bounce.
From the given question,
Height on the first bounce = 6.7
Subsequent bounce reaches a height of the previous bounce = 81%
Suppose the height is h.
So according to the question:
h(6) = height on the first bounce*(subsequent bounce reaches a height of the previous bounce)^6
h(6) = 6.7*(81%)^6
h(6) = 1.892 feet
So the height of sixth bounce is 1.892 feet.

A parallelogram has three of its vertices at $(-1,0)$, $(2,4)$ and $(2,-4)$. What is the positive difference between the greatest possible perimeter and the least possible perimeter of the parallelogram
Answers
The difference in perimeters is 6.
We have 3 possible points for the last vertex.
These are
[ -1 + 2 , 0 + 4 ] - [ 2 , -4 ] = [ [ 1 , 4] - [2 , - 4 ] = ( -1, 8 )
The perimeter of this parallelogram = [tex]2 [ \sqrt{(-1-2)^{2} + (8-4)^2]} + 8][/tex]
= [tex]2 [ \sqrt{9+16}+ 8 ][/tex]
= 2 [ 5 + 8 ]
= 26
Another possible point is
[ 2 + 2, 4 - 4] - [-1,0] = [ 4, 0] - [ -1,0] = (5,0)
The perimeter of this parallelogram
= [tex]2 [ \sqrt{(5-2)^{2} +(0-4)^{2} } + \sqrt{(2+1)^{2}+ (4-0)^{2} } ][/tex]
= [tex]2 [ \sqrt{3^{2}+ 4^{2} } + \sqrt{3^{2}+ 4^{2} }][/tex]
= [tex]2(\sqrt{25} +\sqrt{25})[/tex]
= 2(5 + 5)
= 20
The third feasible point won't change either the largest perimeter of 26 or the smallest perimeter of 20; therefore, we don't need to calculate it.
Difference = 26-20
= 6
Hence, the difference in perimeters is 6.

For which values of k the pair of equations KX 3y K − 3 and 12x Ky K have no solution?
Answers
K must be equal to 0, for the pair of equations to have no solution.
For the pair of equations KX + 3y - K = 0 and 12x + Ky - K = 0 to have no solution, the value of K must be such that the two equations have no common solution.
This can be done by equating the two equations and solving for K.
KX + 3y - K = 0
12x + Ky - K = 0
Subtracting equation (1) from equation (2)
11x + 3y = 0
Divide both sides by 3
x + y = 0
Therefore, K must be equal to 0, for the pair of equations to have no solution.

Answers
Answer:
936
Step-by-step explanation:
First calculate the volume of each container. to calculate volume, multiply the length * width * height.
For Container A, the volume is 13 * 19 * 25 = 6175 inches.
For Container B, the volume is 13 * 13 * 31 = 5239 inches.
6175 - 5239 = 936 so the volume Container A is 936 cubic inches greater than the volume of Container B.
