Answer:
the answer is [tex]27[/tex]
Step-by-step explanation:
First, you need to substitute a, b, and c for their sums
So your new problem should look like this... [tex]2+\left(3-\left(-2\right)\right)^2[/tex]
Then you can begin solving this problem using PEMDAS
So first you're going to start w/ the parenthesis... [tex]3-\left(-2\right)[/tex] which equals 5
Next, you're going to calculate the exponents, so it should look like this... [tex]5^{2}[/tex] which equals [tex]25[/tex]
So now your problem should look like this... [tex]5+25[/tex] which equals [tex]27[/tex]
So your answer is [tex]27[/tex]
hope this helps!

If I have three consecutive integers and three consecutive even integers how would they be represented differently? Explain. ***Three consecutive integers can be represented as x, x+1, and x+2
9514 1404 393
Answer:
even integers differ by 2, consecutive integers differ by 1
Step-by-step explanation:
Often problems involving consecutive integers use a variable (x) to represent the least of them. In that situation, ...
consecutive integers are x, x+1, x+2
consecutive even (or odd) integers are x, x+2, x+4.
__
I often find it convenient to use the variable to represent the middle of the three integers. In that case, the representations are ...
consecutive integers: x-1, x, x+1
consecutive even (or odd) integers: x-2, x, x+2.
_____
In somewhat rare cases, you need to ensure that the integers are even, not odd, so the representation can be ...
consecutive even integers: 2n, 2n+2, 2n+4 . . . . where n is any integer

Suppose you live in Los Angeles, California, where the temperature is 60ºF and going down at a rate of 2ºF an hour. You are talking on the phone to your friend who lives in Vancouver, Canada, where the temperature is 35ºF and going up at a rate of 3ºF an hour. If the temperatures continue to change at the same rates, how long would you and your friend have to talk before they would be equal? Write an equation and then solve it.
Answer:
5 hours
Step-by-step explanation: in 5 hours 60 degrees would become 50 degrees and so wold the 35 degrees.

Rhombus WXYZ with vertices W(1,5), X(6, 3),
Y(1, 1), and Z(-4, 3) in the x-axis.
9514 1404 393
Answer:
W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate. The x-coordinate remains unchanged.
The reflected points are ...
W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
Transformation involves changing the position of a shape
The coordinate of the rhombus after transformation is: W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
The coordinates of the rhombus are given as:
W(1,5), X(6, 3), Y(1, 1), and Z(-4, 3)
The rule of reflection across the x-axis is:
[tex](x,y) \to (x,-y)[/tex]
When the above rule is applied to the rhombus, the image of the rhombus becomes
W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)
Hence, the coordinate of the rhombus after transformation is: W'(1,-5), X'(6,-3), Y'(1,-1), Z'(-4,-3)

a) what is the null and alternative hypothesis
b) determine the test statistic
Answer:
a)
the null and alternative hypothesis will be;
Null hypothesis H₀ : Ц = 18 ug/g
Alternative hypothesis H₁ : Ц < 18 ug/g
b) the Test Statistic = -1.47
Step-by-step explanation:
Given data;
x = 22.5 , 9 , 18.5 , 22 , 16 , 18.5 , 15 , 3 , 8, 6
number of observation n = 10
level of significance ∝ = 0.01
a)
the null and alternative hypothesis will be;
Null hypothesis H₀ : Ц = 18 ug/g
Alternative hypothesis H₁ : Ц < 18 ug/g
b)
Test statistics;
using the formula;
t = (x" - Ц) / (s/√n)
x" is the sample mean
s is the standard deviation
Ц is the population mean ( 18 )
n is the number of observation ( 10 )
for first we get our mean x"
mean x" = ∑x / n
mean x" = (22.5 + 9 + 18.5 + 22 + 16 + 18.5 + 15 + 3 + 8 + 6) / 10
mean x" = 138.5 /10
mean x" = 14.85
Next we find the standard deviation s
standard deviation s = √[ (∑(x-x")²) / (n - 1)]
x (x - x") (x - x")²
22.5 7.65 58.5225
9 -5.85 34.2225
18.5 3.65 13.3225
22 7.15 51.1225
16 1.15 1.3225
18.5 3.65 13.3225
15 0.15 0.0225
3 -11.85 140.4225
8 -6.85 46.9225
6 -8.85 78.3225
total 437.525
so we substitute to get our standard deviation
standard deviation s = √[ ( 437.525 / (10 - 1)]
= √[ 437.525 / 9]
= √48.6138
standard deviation s = 6.9723
Finally our we substitute our values into the Test statistics formula
t = (x" - Ц) / (s/√n)
t = (14.85 - 18) / (6.9723/√10)
t = -3.25 / 2.2048
t = -1.47
Therefore the Test Statistic = -1.47

f(x)=x+7 g(x)=4x^2-9 h(x)=-2x+1 what is the value of h(f(g(2)))
Answer:
- 27
Step-by-step explanation:
Evaluate from the ' inside out ' , that is
Evaluate g(2) then use this value to evaluate f(x) then use this value to evaluate h(x)
g(2) = 4(2)² - 9 = 4(4) - 9 = 16 - 9 = 7, then
f(7) = 7 + 7 = 14 , then
h(14) = - 2(14) + 1 = - 28 + 1 = - 27

Given that, a plumber charges a base fee of $60, and then each hour of work costs $15, yesterday, Joe hired the plumber to fix his sink, at a total cost of 240.
The equation for total cost t for working x hours will be,
60 + 15x = t
According to given situation,
60 + 15x = 240
15x = 180
x = 12
Hence, the plumber worked for 12 hours.

The sum of two consecutive odd numbers is 56. Find the numbers. Write your answer as two numbers separated by a comma
Answer:
27,29
Step-by-step explanation:
Let the two numbers be represented by x and y. We know they are consecutive odd numbers so we can write one of them, lets use y, as y = x+2
x+y=56
x+(x+2)=56
2x=54
∴x=27
y=x+2
y=27+2
y=29
