For the kiddie teacup ride at a carnival a person needs to be over 36 inches and at most 60 inches tall. Write an inequality that describes all the heights that are eligible to ride
Given:
For the kiddie teacup ride at a carnival a person needs to be over 36 inches and at most 60 inches tall.
To find:
The inequality that describes all the heights that are eligible to ride.
Solution:
Let h represents the heights that are eligible to ride.
For the kiddie teacup ride at a carnival a person needs to be over 36 inches. It means, height should be greater than 36 inches.
[tex]h>36[/tex] ...(i)
For the kiddie teacup ride at a carnival a person needs to be at most 60 inches tall.
[tex]h\leq 60[/tex] ...(ii)
Using (i) and (ii), we get
[tex]36<h\leq 60[/tex]
Therefore, the required inequality is [tex]36<h\leq 60[/tex].

Answer:
For the function: [tex]g(x)=-x^2-3x+5[/tex], the average rate of change of function over the interval [tex]-7\leq x\leq 2[/tex] is 2
Step-by-step explanation:
We are given function: [tex]g(x)=-x^2-3x+5[/tex], we need to find average rate of change of function over the interval [tex]-7\leq x\leq 2[/tex]
The formula used is: [tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}[/tex]
We have b=2 and a= -7
Finding f(b) and f(a)
Finding g(b) by putting x=2
[tex]g(x)=-x^2-3x+5\\g(2)=-(2)^2-3(2)+5\\g(2)=-4-6+5\\g(2)=-10+5\\g(2)=-5[/tex]
Finding g(a) by putting x=-7
[tex]g(x)=-x^2-3x+5\\g(-7)=-(-7)^2-3(-7)+5\\g(-7)=-49+21+5\\g(-7)=-23[/tex]
Now, finding average rate of change when g(b)=-5 and g(a)=-23
[tex]Average \ rate \ of \ change=\frac{g(b)-g(a)}{b-a}\\Average \ rate \ of \ change=\frac{-5-(-23)}{2-(-7)}\\Average \ rate \ of \ change=\frac{-5+23}{2+7}\\Average \ rate \ of \ change=\frac{18}{9}\\Average \ rate \ of \ change=2[/tex]
So, Average rate of change = 2
Therefore for the function: [tex]g(x)=-x^2-3x+5[/tex], the average rate of change of function over the interval [tex]-7\leq x\leq 2[/tex] is 2

what is the greatest common factor of 35+14
Answer:
7
Step-by-step explanation:
When you multiply two numbers together to get a product, those two numbers are considered factors of the product. There are certain operations in math that require comparing two or more numbers and identifying the largest factor they have in common. This is called the greatest common factor (GCF).
Answer:
The first step to find the gcf of 14 and 35 is to list the factors of each number. The factors of 14 are 1, 2, 7 and 14. The factors of 35 are 1, 5, 7 and 35. So, the Greatest Common Factor for these numbers is 7 because it divides all them without a remainder.
so 7 is the greatest common factor of 35+14
The factors of 14 are 1,2,7,14; The factors of 35 are 1,5,7,35.
"how may I apply the distributive property to this expression."
By factoring out 7, the expression 35+14 = 7(5 + 2) and so you have an alternative way of computing the sum.
49 = 7(7).

answer of 5 1/2 - 3 5/8
Answer:
3
Step-by-step explanation:
5 1/2 = 5 × 2 + 1/2 = 11/2
3 5/8 = 3 × 8 + 5/8 = 29/8
Now,
5 1/2 - 3 5/8 = 11/2 - 29/8
11/2 - 29/8
11 × 8 - 29 × 2/8 × 2
88 - 58/10
30/10 = 3

Given:
The set of ordered pairs.
To find:
Which set of ordered pairs represents a function?
Solution:
A set of ordered pairs represents a function, if there exist unique output value for each input value.
In option A,
{(2, 9), (5, 9), (1, -6), (-5, 5)}
It is a function because all input has unique outputs.
In option B,
{(6, 6), (6, 8), (-8, -7), (-3, -8)}
For x=6, there exist two outputs y=6 and y=8. So, it is not a function.
In option C,
{(1, 8), (9, -3), (7, -4), (7, -6)}
For x=7, there exist two outputs y=-4 and y=-6. So, it is not a function.
In option D,
{(-5, -1), (-3, -7), (-5, 3), (-7, -4)}
For x=-5, there exist two outputs y=-1 and y=3. So, it is not a function.
Therefore, the correct option is A.
From the given option, the set of ordered pairs that represents a function is {(2, 9), (5, 9), (1, -6), (-5, 5)\}
Ordered pair of a functionA coordinate is known to represents a function if all the domain values have a unique value in the codomain.
The x-coordinate point should not be repeated for the coordinate to be a function, otherwise it is not a function.
From the given option, the set of ordered pairs that represents a function is {(2, 9), (5, 9), (1, -6), (-5, 5)\}

What is the value of g(2)?
Answer:
A.1
Step-by-step explanation:
looking at the function, you can see that you should use the second equation, x^3-9x^2+27x-25, x>=2
step 1: insert 2 into the equation. (2)^3-9(2)^2+27(2)-25
step 2: simplify equation 8-36+54-25=1
The value of function g(2) is 1. Therefore, option A is the correct answer.
The given function is g(x)=[tex]\left \{ {{(\frac{1}{2} )^{x-3} \hspace{6em} x < 2} \atop {{x^{3}-9x^{2} +27x-25} } \hspace{6em}x \geq2}} \right.[/tex].
We need to find the value of g(2).
What is the function?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Now, g(2)= [tex](\frac{1}{2} )^{x-3} =2[/tex]
g(2)=2³-9(2)²+27×2-25
=8-36+54-25=1
The value of function g(2) is 1. Therefore, option A is the correct answer.

Answer:
y = (-9/8)x + 7
Step-by-step explanation:
the line equation for slope intercert form looks like this
y = mx + b
m is the slope
b is the y intercept
The line intercepts the y at b= 7 (as noted in point (0, 7)
To find slope, use the 2 points given and the slope formula
m = (y2 - y1) / (x2-x1)
point (x1, y1) is (0, 7) and
point (x2, y2) is (8, -2)
plug in the correct spots for m = (y2 - y1) / (x2-x1)
m = (-2 - 7) / (8 - 0) = -9 / 8
substitute y = mx +b = (-9/8)x + 7

Mr. Florean opened an account with deposit of $5,000. The account earned 7.5% annual simple interest. He did not make any additional deposits or withdrawals. After some time, the balance of the account was $6,500. How many years did it take for mr.Flores to have a balance of $6,500?
Answer:
4 years
Step-by-step explanation:
The simple interest = $6,500 - $5,000 = $1500
From the formula for simple interest;
I=PRT/100
T= 100 I/PR
T= 100 × 1500/5000 × 7.5
T= 150000/37500
T= 4 years

9x = 72
9x/9 = 72/9
x = 8
Answer: Answer: x=8
Step-by-step explanation:
12x+12=3x+84
Subtract 12 on both sides:
12x+12-12=3x+84-12
12x=3x+72
Subtract 3x on both sides:
12x-3x=3x-3x+72
9x=72
Divide 9 on both sides:
9x/9=72/9

An electrician charges an hourly rate of $60, but also charges a fixed fee for making house calls regardless of time spend on the job. One day, the electrician earned a total of $350 for a 5 hour job. Write an equation for C,C, in terms of t,t, representing the total cost of the electrician's services if the electrician spends tt hours at the house working.
Answer:
$50
Step-by-step explanation:
Step one:
charges per hour= $60
We are told that the electrician earned $350
for a job that took 5hours
The linear equation to represent his earnings is
let the flat fee be x
C=60t+x------------1
so for C=$350
Required
the flat fee
350=60(5)+x
350=300+x
collect like terms
x=350-300
x=50
Flat fee is $50
Answer: C=60t+50
Step-by-step explanation:
$60 an hour,
5 hours before the fixed fee is only $300
but the amount he made for a 5 hour house call was $350,
making the fixed fee $50
