The coordinates of the points P, Q and R are given by (-2, 1), (1, 4) and (4, k) respectively. Find the value(s) of k if
(b) PQ=QR(clue:distance).
There are two values of k based on the assumption that PQ = QR and the definition of distance and the Pythagorean theorem, k₁ = 7 and k₂ = 1.
How to find the missing value of a coordinate
Herein we can find the value of the missing coordinate of point by the Pythagorean theorem, which is described below:
PQ = QR (1)
[tex](Q_{x}-P_{x})^{2} + (Q_{y}-P_{y})^{2} = (R_{x}-Q_{x})^{2} + (R_{y}-Q_{y})^{2}[/tex]
If we know that P(x, y) = (- 2, 1), Q(x, y) = (1, 4) and R(x, y) = (4, k), then the missing value of the point R is:
[1 - (- 2)]² + (4 - 1)² = (4 - 1)² + (k - 4)²
(k - 4)² = 9
k - 4 = ± 3
k = 4 ± 3
There are two values of k based on the assumption that PQ = QR and the definition of distance and the Pythagorean theorem, k₁ = 7 and k₂ = 1.

Two friends, Olivia and Melanie, took summer jobs. The equation y=22.2xy=22.2x represents Melanie's earnings in dollars and cents, yy, for working xx hours. Olivia earned $1156 in 40 hours. How much less per hour does Melanie earn than Olivia?
Answer:
$6.70 per hour
Step-by-step explanation:
We want to compare the pay for 1 hour's work.
Melanie's payThe equation tells us that her pay for working 1 hour can be found from the equation using x=1.
y = 22.2x
y = 22.2×1 = 22.2 . . . . pay for 1 hour
Melanie earns $22.20 per hour.
Olivia's payWe assume that Olivia's pay is proportional to hours worked, so pay for 40 hours will be 40 times 1 hour's pay.
pay per hour = $1156/(40 h) = $28.90/h
Olivia earns $28.90 per hour.
Pay differenceThe difference in their rates of pay is ...
$28.90 -22.20 = $6.70
Melanie earns $6.70 less per hour than Olivia.

Given that a bag of m&ms has 21 brown candies, 15 orange candies, 10 yellow candies, 14 red candies, and 5 green candies, find the probabilities
The probability of drawing brown candies , orange candies, yellow candies, red candies, green candies is 0.323 , 0.231 , 0.154 , 0.215 ,0.077
What is Probability ?Probability is the study of likeliness of an event to happen.
It is given that a bag of candies that have
21 brown candies
15 orange candies,
10 yellow candies,
14 red candies,
5 green candies,
probabilities of drawing each candy =?
Total Candies = 21 +15+10+14+5 = 65
Probability = No. of chances / Total outcomes
Probability of drawing Brown candies = P(B) = 21 /65 = 0.323
Probability of drawing Yellow candies = P(Y)= 10/65= 0.154
Probability of drawing Orange candies = P(O) = 15/65= 0.231
Probability of drawing Red candies =P( R) = 14/65= 0.215
Probability of drawing Green candies = P(G) = 5/65= 0.077

They work-infested $18,000 into accounts, one yielding 4% interest and the other yielding 12%. If he received a total of $1,280 and interest at the end of the year, how much did he invest at 4%?
Answer:
$11,000
Step-by-step explanation:
Let amount invested for 12% yield be p . Amount for 4% yield is therefore (18000-p)
Interest for 12%: 12% of p=0.12p
Interest for 4%: 4% of (18000-p)=0.04(18000-p)=720-0.04p
Total interest:
=0.12p + (720-0.04p)
=0.12p-0.04p+720
=0.08p+720
But we already know the total interest is 1280
Therefore: 0.08p+720=1280
0.08p=1280-720
0.08p=560
p=560÷0.08
p=7000
Therefore at 4% the person invested:
(18000-p)
18000-7000

The graph is of a function in the form p(t) = a*b^t. What is the function?
Answer:
p(t) = 5*2^t
Step-by-step explanation:
We can solve for 'a' and 'b' using the point coordinates shown on the graph.
SetupSubstituting for (t, p(t)), the two equations we can make from the given points are ...
p(t) = a*b^t
5 = a*b^0 . . . . . . . (t, p(t)) = (0, 5)
10 = a*b^1 . . . . . . . (t, p(t)) = (1, 10)
SolutionThe first equation tells you ...
5 = a
The second equation tells you ...
10 = 5*b
2 = b
EquationThe function is ...
p(t) = a*b^t
p(t) = 5*2^t

all that apply.
p(x) = 14(x + 7)² + 1
g(x) = -5(x + 10)² - 1
s(x) = –(x − 1)? +0.5
g(x) = 2x² + 10x-35
t(x) = -2x² - 4x - 3
Using translation concepts, the functions that have a maximum and are transformed to the left and down of the parent function are given by:
g(x) = -5(x + 10)² - 1t(x) = -2x² - 4x - 3What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
For the translations, we have that:
Shift left, hence x -> x + a, a > 0.Shift down, hence y -> y - a, a > 0.Having a maximum means that the leading coefficient is negative.The functions that respect these conditions are:
g(x) = -5(x + 10)² - 1t(x) = -2x² - 4x - 3 = -2(x² + 2x) - 3 = -2(x + 1)² - 1More can be learned about translation concepts at https://brainly.com/question/4521517
