31) Given the parent function f(x) = |x|, describe the translation of the function g(x) = 2|x] + 9 from the parent function.
Answer:
the graph is shifted up 9, compressed by a factor of 2
Step-by-step explanation:
General form of an absolute value equation:
f(x)= a|x - h| + k
The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h tell us how far the graph shifts horizontally and vertically.
parent function f(x) = |x|,
the translation of the function g(x) = 2|x| + 9 from the parent function.
- the +9 shift the graph up 9
- the 2 compresses the graph

7. how many tiles measuring
20cm x 20cm
are needed to tile a bathroom 3.5m long
and 2.8m wide?
Answer:
245 tiles
Step-by-step explanation:
1 meter = 100 cm
Area of bathroom = 3.5m x 2.8m = 350x280 = 9800 cm²
Area of each tile = 20cm x 20cm = 400 cm²
Total number of tiles required = 9800/400 = 245
Note
Strictly speaking we have to find out how many tiles can be fitted in the length and breadth of the bathroom. Since the bathroom is 350 cm wide, we can fit 350/20cm = 17.5 tiles. However, there is no concept of 1/2 tile so the question has an ambiguity. along the width, we can fit 280/10 = 14 tiles
17.5 x 14 = 245 but if the question is reworded to how many tiles do we need to purchase to floor the bathroom it would be 18 x 14 = 252

A yogurt shop offers 25 flavors of frozen yogurt. Evie randomly chooses 3 different flavors for her banana split. What is the probability she chooses chocolate, vanilla, and strawberry?.
The probability of choosing chocolate, vanilla, and strawberry flavor is 1 / 625
What is the probability?Probability determines the likelihood that a random event would happen. The probability the event occurs with certainty is 1 and the probability that the event would not occur with certainty is 0.
The probability of choosing chocolate, vanilla, and strawberry flavor = (1 / 25)³ = 1 / 625

What is the length of AB?
12 units
10 units
6 units
14 units
Answer:
10 units
Step-by-step explanation:
From the graph,
Coordinates of A = (-7,-6)
Coordinates of B = (1,0)
Distance between two coordinates is given by the formula,
[tex] = > \sqrt{( {x_{2}-x_{1}}^{2} ) + ( {y_{2}-y_{1}}^{2} )} [/tex]
Let A(-7,-6) = (x1 , y1)
B(1,0) = (x2 , y2)
=> AB = √[( 1 - (-7))² + ( 0 - (-6))²]
=> AB = √ 8² + 6² = √ 64 + 36 = √100
=> AB = 10 units
Skyler goes to a school which has 1000 students in it.

Overview
Sampling Populations
Answer:
it's estimated that 750 students in the whole school dislike the 8:30am start time.
Step-by-step explanation:
Since 30 of the 40 students said "no", it means 30/40, or 3/4 of the random sample disliked the 8:30am start time. Multiply this by the whole population: 1,000 × (3/4) = 750.
Another way to check this is using 10/40 = .25 and doing 1000x.25 = 250 (the amount of students who liked it). Then subtract from whole population and it's 750.

A quadratic function has one solution at x=-2-√6
What is the exact value of the other root?
x= ________
Answer:
Step-by-step explanation:
Discussion
The form of this root is a "mirror image" of the root that is given. They come in pairs.
So the exact value of the other root is
x = - 2 + √6
You should be very careful looking at this root. The only difference is the plus sign where the minus sign used to be.
The given root has to be of the form a rational number ± an irrational number.
Later on, when you get into higher math classes, you will find there is another kind of number that this same rule applies to.

A jar contains 3 blue marbles and 2 red marbles.
A marble is randomly selected from the jar and replaced, and then a second marble is chosen.
The probability that a blue marble was chosen both times is __%.
Answer: 9/25 or 36%
Step-by-step explanation:
The first time it is a probability of 3/5, and the second blue also has a prbability of 3/5. Multiply them together since it is an "and" situation, and you get 9/25. Or, in percentages, it is 60% * 60%, or 0.6 * 0.6, which is 36% or 0.36. Hope this helps!

which point best represents \sqrt{10}
Answer:
Point Q
Step-by-step explanation:
Find the perfect squares that are either side of 10.
Perfect squares: 1, 4, 9, 16, 25, ....
Therefore, 10 is between 9 and 16.
[tex]\implies \sqrt{9} < \sqrt{10} < \sqrt{16}[/tex]
[tex]\implies 3 < \sqrt{10} < 4[/tex]
So √10 is between 3 and 4.
As 10 is closer to 9 than it is to 16, √10 is closer to √9 than √16, which means that √10 is closer to 3.
Therefore, point Q best represents √10
