Answer:
[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]
Step-by-step explanation:
Given [Missing]
[tex]A = (-3,4)[/tex]
[tex]B = (1,3)[/tex]
[tex]C =(3,6)[/tex]
[tex]D =(1,6)[/tex]
The first transformation: reflection across the y-axis.
The rule is: [tex](x,y)==>(-x,y)[/tex]
So:
[tex]A = (-3,4)[/tex] ==>[tex]A' = (3,4)[/tex]
[tex]B = (1,3)[/tex] ==> [tex]B' = (-1,3)[/tex]
[tex]C =(3,6)[/tex] ==> [tex]C' = (-3.6)[/tex]
[tex]D =(1,6)[/tex] ==> [tex]D' = (-1,6)[/tex]
Translation 2 units down
The rule is: [tex](x,y)==>(x,y-2)[/tex]
So:
[tex]A' = (3,4)[/tex] ==> [tex]A" =(3,4-2) =(3,2)[/tex]
[tex]B' = (-1,3)[/tex] ==> [tex]B" = (-1,3-2) = (-1,1)[/tex]
[tex]C' = (-3.6)[/tex] ==> [tex]C" = (-3,6-2) = (-3,4)[/tex]
[tex]D' = (-1,6)[/tex] ==> [tex]D" =(-1,6-2) = (-1,4)[/tex]
Hence:
[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]

What are the three ordered pairs that should be in the table of values y=2x-3
Answer:
(-2, -7), (0, -3), (2, 1)
Step-by-step explanation:
Equation is given as y = 2x - 3.
To complete the table, plug in each value of x into y = 2x - 3 to get their corresponding y-value.
✔️When x = -2:
y = 2(-2) - 3
y = -4 - 3
y = -7
✔️When x = 0:
y = 2(0) - 3
y = -3
✔️When x = 2:
y = 2(2) - 3
y = 4 - 3
y = 1

A car purchased for $20,000 depreciates annually at a rate of 8%. What will be the approximate value of the car in the 10th year?
Answer:
$4000
Step-by-step explanation:
20000x0.08=1600
1600x10=16000
20000-16000=4000
Answer:
$8687.76
Step-by-step explanation:
100-8=92
20,000*0.92=18400 (This is after one year)
20,000*0.92^10= 8687.7690 (After 10 years)
A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The manufacturer claims that the average amount of the chemical is 95 mg. It is known that the standard deviation in the amount of the chemical is 5 mg. A random sample of 25 batches of the new drug is tested and found to have a sample mean concentration of 89.9 mg of the active chemical.
Calculate the 95% confidence interval for the mean amount of the active chemical in the drug. Give your answers to 2 decimal places. (suppose to be number less than and equal to mean less than and equal to another number)
Answer:
The 95% confidence interval is "87.94, 91.86".
Step-by-step explanation:
The given values are:
Sample batches,
n = 25
Sample mean concentration,
[tex]\bar{x}[/tex] = 89.9 mg
Amount of chemical,
σ = 5
α = 0.05
The critical value from Z table will be:
= [tex]Z(\frac{\alpha}{2} )[/tex]
= [tex]Z(\frac{0.05}{2} )[/tex]
= [tex]1.96[/tex]
Now,
The confidence interval will be:
= [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]
= [tex]89.9 \pm1.96\times 1[/tex]
Lower limit will be:
= [tex]89.9 -1.96\times 1[/tex]
= [tex]87.94[/tex]
Upper limit will be:
= [tex]89.9 +1.96\times 1[/tex]
= [tex]91.86[/tex]
Is (x-4) a factor of x^3 +x^2 -16x-16x 3 +x 2 −16x−16 ?

Step-by-step explanation:
[tex] \triangle TPR \sim \triangle SQR... (given) [/tex]
[tex] \therefore \frac{TP}{SQ} = \frac{PR}{QR}[/tex]
[tex] \therefore \frac{TP}{SQ} = \frac{PQ+QR}{QR}[/tex]
[tex] \therefore \frac{3}{x} = \frac{1\frac{1}{3} +2 \frac{2}{3}}{2 \frac{2}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{\frac{4}{3} + \frac{8}{3}}{\frac{8}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{\frac{12}{3}}{\frac{8}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{12}{8}[/tex]
[tex] \therefore x = \frac{8\times 3}{12}[/tex]
[tex] \therefore x = \frac{24}{12}[/tex]
[tex] \therefore x =2[/tex]

To the nearest 1000, there are 18,000 people at a festival . Write down the minimum possible number of people at the festival
Answer:
17500
Step-by-step explanation:
17499 rounds down
17500 rounds up
The number of people is an illustration of approximation and estimation
The minimum possible number of people at the festival is 17500
The approximated number of people is:
People = 18000
Because 18000 represents people, it means that the population is a whole number
The smallest whole number that can be approximated to 18000 is 17500
i.e.
People = 17500
Hence, the minimum possible number of people at the festival is 17500

In the last several weeks, 18 days saw rain and 29 days saw high winds. in the same time period 7 days saw both rain and high winds. How many days saw either rain or high winds
Answer:
40 days saw either rain or high winds
Step-by-step explanation:
We solve this question using Venn sets.
I am going to say that:
Set A: Rain
Set B: High winds.
18 days saw rain
This means that [tex]A = 18[/tex]
29 days saw high winds
This means that [tex]B = 29[/tex]
7 days saw both rain and high winds.
This means that [tex]A \cap B = 7[/tex]
How many days saw either rain or high winds?
This is
[tex]A \cup B = A + B - A \cap B[/tex]
Sp
[tex]A \cup B = 18 + 29 - 7 = 40[/tex]
40 days saw either rain or high winds

Answer:
Four (4); 45; at least; 181.
Step-by-step explanation:
Ali has four friends that owe him x dollars each. His parents owe him $45 for doing chores last week. He recalls that people owed him at least $181.
To find how much money each of Ali's friends owe him;
Given the algebraic expression;
4x + 45 ≤ 181
4x ≤ 181 - 45
4x ≤ 36
Dividing both sides by 9, we have;
x ≤ 9
Therefore, Ali's friends owe him at least $9 each.

Four (4); 45; at least; 181.
