if a parabola is horizontally translated 15 units left, stretch by a factor of 20, vertically translated down 30 units and reflected in the x axis determine the equation of the parabola in vertex form
Answer:
y' = a(x'- ((h-15)/20))² + -(k-30)
Step-by-step explanation:
Vertex: (h,k)
horizontally translated 15 units left: (h-15 , k)
stretch by a factor of 20: ((h-15)/20 , k)
vertically translated down 30 units: ((h-15)/20 , k-30)
reflected in the x axis: ((h-15)/20 , -(k-30))
Vertex' (h' , k'): ((h-15)/20 , -(k-30))
Equation: y' = a(x'-h')² + k'
y' = a(x'- ((h-15)/20))² + -(k-30)

Find the distance between (2, 9) & (-1, 4). Round to the nearest tenth.
Answer:
1.7
Step-by-step explanation:
To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].
y2 = 4, y1 = 9, x2 = -1, x1 = 2
Insert the values into the equation:
[tex]\frac{4-9}{-1-2}[/tex]
Simplify:
[tex]\frac{4-9}{-1-2}= \frac{-5}{-3}=\frac{5}{3}[/tex][tex]\frac{}{} =1.7[/tex]
The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.

Answer #1:
X= 75
Y= 15
Step-by-step explanation: The first equation is x+y=90 and then your next equation is x=5y. After you have those two equation you sub them in 5y+y=90 and once you solve for y you solve for x.

Answer: option 3
Step-by-step explanation:
solve for x
x^9=12^2x12^7
Answer:
12Step-by-step explanation:
Hi!
Here is your answer,
I will explain in step by step,
[tex] {x}^{9} = {12}^{2} \times {12}^{7} [/tex]
Here we can simplify this further using this law,
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
So we will get,
[tex] {x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9} [/tex]
Since the powers are same we can cancel it out and we will get,
[tex]x = 12[/tex]

URGENT find the volume of these rectangular prisms. Round answers to the nearest tenth when necessary
Answer:
A= 120
b=200 (if the number on the bottom is a 4 thats cut out)
Step-by-step explanation:
for volume u just multiply the 3 numbers it gives u for the models like for example in the picture u do
6*4*5 in no specific order
if its a triangle and volume or area u do that but at the end divide by 2 in area

A toy manufacturer is shipping its newest product, an interactive talking globe, to a major toy store. The packaging for the globe is a rectangular prism that measures 2512 2512 inches high, 18 inches long, and 18 inches wide. The boxes for the globes are packaged into shipping crates that hold 8 globes each. What is the minimum volume of one shipping crate? Explain your answer in the space provided.
Answer:
6 511 104 in³
Step-by-step explanation:
Since we have 1 crate and 8 boxes fit into one crate.
So, volume of one crate, V' = 8 × volume of 1 box, V
Since the box is a rectangular prism of sides 2512 inches high, 18 inches long, and 18 inches wide, its volume, V = lwh where l = length of prism, h = height of prism and w = width of prism.
So, V = lwh = 18 in × 18 in × 2512 in = 813 888 in³
So, V' = 8 × 813 888 in³ = 6 511 104 in³
So, the minimum volume of the crate is 6 511 104 in³
Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle
