Why do we use coordinate planes to do
transformations and dilations?
Answer: a coordinate plane is used in order to track the location of the object.
Translations are congruence transformations that move an object, without changing its size or shape
Dilations are transformations that generate an enlargement

Write the function whose graph is the graph of y=|x| , but is translated 3units to the left and 4 units upward.
y=
Answer:
y=|x+3|+4
Step-by-step explanation:
3 units left is + 3
4 units up is + 4
The graph of function y = |x+3|+4 is translated as 3 units to the left and 4 units upward.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.
For example, If shift up by 1 unit, add 1 to the function
If shift down by 4 units, subtract 4 from the function
To determine the function whose graph is the graph of y=|x| ,
Translated is 3 units to the left and 4 units upward.
x+3 because adding 3 to the x coordinate would shift it over 3
y-4 because subtracting 4 to the y coordinate would shift it up 4
⇒ f(x) = ( x + 3, y - 4 )
⇒ y - 4 = |x+3|
⇒ y = |x+3| + 4
Therefore, the graph of function y = |x+3|+4 is translated as 3 units to the left and 4 units upward.

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 135 millimeters, and a variance of 64. If a random sample of 32 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 3.6 millimeters? Round your answer to four decimal places.
Answer:
0.3264
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ, where
x is the raw score,
μ is the population mean,
σ is the population standard deviation.
(x-μ) = 3.6 mm
σ = √variance = √64 = 8mm
z = 3.6/8
z = 0.45
Using the Probability table
P(x<Z) = 0.67364
P(x>Z) = 1 - P(x<Z)
1 - 0.67364
= 0.32636
Approximately = 0.3264

Write an equation, in slope-intercept form,
for a line that passes through points (-4, 1)
and (2. 4).
Answer:
y = (3/2)x + 7
Step-by-step explanation:
(−4, 1) and (−2, 4)
slope m = rise/run = (4-1)/(-2-(-4)) = 3/2
Slope intercept form is y=mx+b
where m=slope, b = y-inercept
y = (3/2)x + b
Use one of the given points for (x,y) to find b
1 = (3/2)(-4) + b
1 = -6 + b
7 = b
y = (3/2)x + 7

If you divide any number by itself, what is the result? How can you apply this result to the expression -1×60/-1×10?
Answer:
Step-by-step explanation:
Any number divided by itself is 1. In the expression-1 times -10 over -1 times -60 ,the -1s in the numerator and the denominator cancel each other out to give the result , or 6.

Find f’(2) for f(x)=5e^-xln(x^2+5x)
9514 1404 393
Answer:
f'(2) ≈ −1.3508
Step-by-step explanation:
The derivative of the function is ...
f'(x) = 5(-e^-x·ln(x^2 +5x) +e^-x·(2x +5)/(x^2 +5x))
Then ...
f'(2) = 5e^(-2)(-ln(14) +9/14) ≈ -1.3508

-5<2-h or 6h +5<71 chapter 2 test
Answer:
-5<2-h or 6h+5<71
-7<-h or 6h<66
7>h or h<11
h<7 or h<11
Step-by-step explanation:
The inequality that represents the solution of the given set -
- 5 < 2 - h or 6h + 5 < 71 is h < 11.
What is inequality in mathematics?
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given are the following inequalities -
- 5 < 2 - h or 6h + 5 < 71
We will solve the given inequalities one by one -
Inequality - 1
- 5 < 2 - h
Subtract 2 from both sides -
- 7 < - h
Multiply by -1 on both sides -
h < 7
Inequality - 2
6h + 5 < 71
Subtract 5 from both sides -
6h < 66
Divide by 6 on both sides -
h < 11
Now, h can be either -
h < 11 or h < 7
We can write it as a single inequality as -
h < 11 [this set of numbers will include all numbers less than 7]
Therefore, the inequality that represents the solution of the given set -
- 5 < 2 - h or 6h + 5 < 71 is h < 11.

It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes. At this rate:
How many pounds of mashed potatoes can they make with 15 pounds of potatoes?
Answer:
22.5 pounds of mashed potatoes are made from 15 pounds of potatoes.
Step-by-step explanation:
According to the statement, we notice that the amount of pounds of potatoes ([tex]x[/tex]) is directly proportional to the amount of mashed potatoes ([tex]y[/tex]). That is:
[tex]y\propto x[/tex]
[tex]y = k\cdot x[/tex] (Eq. 1)
Where [tex]k[/tex] is the proportionality constant, dimensionless.
Then we eliminate such constant by building this relationship:
[tex]\frac{y_{2}}{y_{1}} = \frac{x_{2}}{x_{1}}[/tex]
[tex]y_{2} = \left(\frac{x_{2}}{x_{1}} \right)\cdot y_{1}[/tex] (Eq. 2)
If we know that [tex]x_{1} = 10[/tex], [tex]x_{2}=15[/tex], [tex]y_{1} = 15[/tex], then the amount of pounds of mashed potatoes is:
[tex]y_{2} = \left(\frac{15}{10} \right)\cdot (15)[/tex]
[tex]y_{2} = 22.5[/tex]
22.5 pounds of mashed potatoes are made from 15 pounds of potatoes.
There are four different sets of objects shown in the answer choices. Select all of the sets of objects that could be modeled by perpendicular lines. Two roads that meet at an intersection. The top of a desk and the floor. A tree and its shadow on the ground. Two stars seen in the sky.
Answer:
Step-by-step explanation:
Select all of the object sets that could be modelled by perpendicular lines.
A perpendicular line is one that divides a 180 degrees line (or a straight line) into two; creating 90 degrees on one hand and 90 degrees on the other.
OPTIONS:
(A) APPLICABLE
Two roads that meet at an intersection can be modelled by perpendicular lines. Use the definition above as a yardstick.
(B) APPLICABLE
The top of the desk to the floor will represent the dividing line while the floor itself will be the 180° line.
(C) NOT APPLICABLE
A tree and its shadow on the ground will only form a right-angled triangle
(D) NOT APPLICABLE
Two stars seen in the sky cannot be modelled by perpendicular lines. They can only be modelled by a straight line; a line which extends from the first star to the other.
