Answer:
range of the given set is { 7,2,4,2,1}
Step-by-step explanation:
. Hello !
When the above kind of set is given the second values of each elements belongs to the range or the y whereas, the first values of the elements belongs to the domain or x.
Thus, domain = {-1,6,0,5,-3}range ={7,2,4,2,1}graph the parabola. y=(x-3)^2-1
Answer:
Step-by-step explanation:
y = (x-3)²-1
This is the equation for an up-opening parabola with vertex (3,-1).
Find the x-intercepts:
0 = (x-3)²-1
(x-3)² = 1
x-3 = ±1
x = 4, 2
The graph crosses the x-axis at (4,0) and (2,0).
Find the y-intercept:
y = (0-3)²-1 = 8
The graph crosses the y-axis at (0,8).
Plot your four points (3,-1), (4,0), (2,0), (0,8). Draw an up-opening parabola through the points.

Factor completely the given polynomial
x(x + 20) + 11(x + 20)
x(x + 20) + 11(x + 20)=
Answer:
(x + 20)(x + 11)
Step-by-step explanation:
x(x + 20) + 11(x + 20) =
Factor out the common factor of x + 20.
= (x + 20)(x + 11)
The binomials make it look complicated, but this is simpler than you think.
Look at this simpler, but similar, example.
Factor xy + 4y
xy + 4y =
You see clearly that y is a common factor, so you factor out y, and you get
= y(x + 4)
In your problem, you have
x(x + 20) + 11(x + 20) =
where (x + 20) is the common factor.
You factor out the common factor, (x + 20). What is left? x + 11 as a factor, so you get
(x + 20)(x + 11)

On April 1, 1986, Casey deposited $1150 into a savings account paying 9.6% interest, compounded quarterly. If he hasn't made any additional deposits or withdrawals since then, and if the interest rate has stayed the same, in what year did his balance hit $2300, according to the rule of 72? A. 1993 B. 1992 C. 1994 D. 1991
In 1993 year his balance will hit $2300.
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, is the formula for compound interest.
Given, On April 1, 1986, Casey deposited $1150 into a savings account paying 9.6% interest, compounded quarterly.
Here the given amount = $1150
Amount after getting compound interest in this amount = $ 2300
Since, $2300 is double to the amount $1150
According to the rule of 72, an amount is doubled if the product of annual rate and period (in years) is equal to 72. Also, with the help of this rule we get the approximate value of rate or time.
Since, Here the annual rate of interest = 9.6%
Let the given amount $1150 is doubled ($2300) in t years.
The, 9.6 × t = 72
⇒ t = 72/9.6 = 7.5
Since he deposited money on April 1 1986,
Thus, Her amount be $2300 on 1993
Therefore, In 1993 year his balance will hit $2300.

In 50 trials both coins land in a shaded box twice. What is the experimental probability that both coins fall into a shaded box?
Answer:
1 / 25
Step-by-step explanation:
Number of trials = 50
Number of successes (number of times both coins land in a shaded box) = 2
Experimental probability = (number of successes / number of trials)
Experimental probability (both coins landing into a shaded box) = 2 / 50
= 1 / 25

Answer:
[tex]99999[/tex]
Step-by-step explanation:
Let the number be [tex]x[/tex].
According to question, if a number is subtracted from 1010001 the difference is 910002.
[tex]1010001-x=910002[/tex]
Transpose [tex]1010001[/tex] to the right side of the equation.
[tex]-x=910002-1010001=-99999\\-x=-99999[/tex]

for what values of x and y is PQRS and parallelogram
Answer:
x = 2
y = 3
Step-by-step explanation:
Measures of opposite sides of a parallelogram are equal.
Therefore,
PQ = SR
2y + 2 = y + 5
2y - y = 5 - 2
y = 3
QR = PS
2x + 3 = y + 4
2x + 3 = 3 + 4 (y = 3)
2x = 7 - 3
2x = 4
x = 4/2
x = 2
Thus, for x = 2 and y = 3, PQRS is a parallelogram.
the percentage of people who took less than 40 secs to complete a task give answer in 1 decimal place
Answer:
63.6%
Step-by-step explanation:
Total number of people that took the test = 110
People who took less than 40 seconds to complete the task = 30 + 40
= 70
The percentage of the people that took less than 40 seconds to complete the task can be determined as follows:
= [tex]\frac{number of people who used less than 40 seconds}{total number of people who took the task}[/tex] x 1100%
= [tex]\frac{70}{110}[/tex] x 100%
= 0.6364 x 100%
= 63.6%
The percentage of the people that took less than 40 seconds to complete the task is 63.6%.
Use Inverse trig functions to solve for the missing angles
D
8.5
F
E
6.5
Answer:
Angle <E is approximately 40 degrees, and angle <D is approximately 50 degrees
Step-by-step explanation:
Since angle <F is clearly 90 degrees, we can find angle E using the cosine function that relates the adjacent side to the angle with the hypotenuse:
[tex]cos(\theta)=\frac{adj}{hyp} \\cos(E)=\frac{6.5}{8.5}\\E = arccos(\frac{6.5}{8.5})\\E\approx 40.12^o[/tex]
And we use the sin function to deal with angle <D:
[tex]sin(\theta)=\frac{opp}{hyp} \\sin(D)=\frac{6.5}{8.5}\\D = arcsin(\frac{6.5}{8.5})\\D\approx 50^o[/tex]

A workman received $110 for working 20 hours. At the same rate of pay, how many hours must he work to earn $187?
Answer:
He must work 34 hours
Step-by-step explanation:
187×20= 3740
3740÷110= 34
If a workman received $110 for working 20 hours. At the same rate of pay, 33.99 hours must be worked to earn $187.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, A workman received $110 for working 20 hours.
We will apply the unitary method in order to solve the given problem.
For $110 he has to work 20 hours.
$110 = 20 hours
For 1 dollar he has to work,
$1 = 20 / 110
$1 =0.1818 hours
The number of hours must he work to earn $187 will be,
$187 = 187 × 0.1818 hours
$187 = 33.99 hours
Thus, if a workman received $110 for working 20 hours. At the same rate of pay, 33.99 hours must be worked to earn $187.
