Answer:
2x²yz(1 - 4y)(1 + 4y)
Step-by-step explanation:
Given
2x²yz - 32x²y³z ← factor out 2x²yz from each term
= 2x²yz(1 - 16y²) ← difference of squares
= 2x²yz(1 - 4y)(1 + 4y)
If a dilation with a scale factor of 5 is performed to ADEF, what will be the
coordinates of the new triangle?
D(-5,-2)
E(-5,3)
F(2,3)
o D'(-25,-10) E'(-25,15) F(10,15)
o D'(-20,-10) E'(-20,15) F'(5,15)
o D'(-1,5) E'(-1,3) F'(5,3)
Answer: · D'(-25,-10) E'(-25,15) F'(10,15)
Answer:
o D'(-25,-10) E'(-25,15) F'(10,15)
Step-by-step explanation:
In dilations, the scale factor is how many times larger than the new image will be.
Great, that explains a lot.
In other words, multiply the x and y-coordinate by the scale factor.
In this case, the scale factor is 5.
D(-5,-2)
-5 ⋅ 5 = -25
-2 ⋅ 5 = -10
E(-5,3)
-5 ⋅ 5 = -25
3 ⋅ 5 = 15
F(2,3)
2 ⋅ 5 = 10
3 ⋅ 5 = 15
Therefore, the new coordinates are:
D' (-25,-10)
E' (-25,15)
F' (10,15)

Answer:

Step-by-step explanation:
You need to use pythagorean theorem (a^2 + b^2 = c^2). In this case 5 is a, 12 is b, and z is c. 5^2 + 12^2 = z^2, this ends up as 169 = z^2. Now you find the square root of 169 which is 13.

Jason just got tired for a new job and will make $80,000 in his first year. Jason was
told that he can expect to get raises of $5,000 every year going forward. How much
money in salary would Jason make in his 23rd year working at this job?
Answer:
$110,080
Step-by-step explanation:
This is an arithmetic sequence because each new term is obtained by adding $5000 to the preivous term.
The general formula for such an arithmetic series is
a(n) = $80,000 + ($5,000)(n - 1)
and so in his 23rd year Jason would make
a(23) = $80,000 + ($5,000)(23 - 1), or
$110,080
Answer:
$110,080 is the answer
The manager of a warehouse would like to know how many errors are made when a product's serial number is read by a bar-code reader. Six samples are collected of the number of scanning errors: 36, 14, 21, 39, 11, and 2 errors, per 1,000 scans each.
Just to be sure, the manager has six more samples taken:
33, 45, 34, 17, 1, and 29 errors, per 1,000 scans each
How reasonable is it to expect that the small sample represents larger samples?
Answer:1A. 20.5
2A. 14.54
1B. 14.625
2B. quite good reasonable
Step-by-step explanation:
Mean is used to measure central tendency (i.e. representative of data) and standard deviation is use to measure dispersion of data. The formula use to calculate mean and variance is :
1A. Mean of six sample =
⇒
⇒ Mean = 20.5
Standard deviation of six sample =
⇒ σ = 14.54
2A. Total number of error = 36 + 14 + 21 + 39 + 11 + 2 = 123
Total number of error made by all scans is 123 error per 6000 scans.
1B. Mean of all 12 samples is:
⇒
⇒ Mean = 23.5
Standard deviation of all 12 samples =
⇒ σ = 14.625
2B. Taking small sample instead of large sample can be quite risky sometimes as larger sample give us more accurate result than small sample.
But here we can take a small sample because the mean of both the size of the sample is near about.

Two sides of a parallelogram are 200 feet and 580 feet. The measure of the angle between these sides is 112°. Find the area of the parallelogram to the nearest square foot.
Answer:
Area of the parallelogram = 107,555 square feet
Step-by-step explanation:
Let
h = height of the parallelogram
sin (112°) = h/200 feet
h = sin(112°) × 200
h = 0.927184 × 200
= 185.4368 feet
h = 185.44 feet
Area of the parallelogram = base × height
= 580 feet × 185.44 feet
= 107,555.2 square feet
To the nearest square root = 107,555 square feet
Area of the parallelogram = 107,555 square feet

Place the numbers 40 and 100 into the proportion. (Whole)(percents) ----------- (Part) what goes where?
Answer:
Step-by-step explanation:
Hard to tell how the question should read.
40/100 = 40%
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Proportion means writing in fraction form as numerator and denominator.
40/100 = 40%
The proportion of 40 and 100 is 40%.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have.
40 and 100.
Proportion means writing in fraction form as numerator and denominator.
So,
If we write 40/100 we get 40%.
This means 40 out of 100.
Thus,
40/100 = 40%
The proportion of 40 and 100 is 40%.

1) In the figure below, m_2 = 60°. Find the measure of each angle. Write which postulate(s) or
theorem(s) you used.
a ) angle 1
b) angle 2
c) angle 8
Answer:
Step-by-step explanation:
From the picture attached,
Two lines are the parallel lines and a third line (transversal line) is intersecting these parallel lines.
m∠2 = 60°
a). m∠1 + m∠2 = 180°
m∠1 + 60° = 180°
m∠1 = 180° - 60°
m∠1 = 120°
b). m∠2 = 60° [Given]
c). m∠2 = m∠8 = 60° [Alternate exterior angles are equal]
