Convert the following from vertex form to standard form
Answer:
option 3
Step-by-step explanation:
Answer:
-3x²+12x-16
Step-by-step explanation:
-3(x-2)²-4
expand (x-2)² first = (x-2)(x-2) = x²-2x-2x+4 or x²-4x+4
distribute -3
-3(x²-4x+4) = -3x²+12x-12-4
= -3x²+12x-16

Is, “What is your favorite color?” A statistical question? Why or why not?
Answer:
This is a statistical question because to answer this question, you would collect data by asking students about their favorite colors, and there would be variability in the data. The favorite color would not be the same for every student

Debbie had $100.00 to spend on shoes and shirts. She bought 1 pair of shoes for $53.84, including sales tax. Each shirt costs $8.19, including sales tax. What is the maximum number of shirts Debbie can purchase?
she can buy 5 shirts maximum
100-53.84=46.16 that is how much she has left to spend on shirts. 46.16÷8.19=5.63 but you can't have 0.63 shirts so in the end she can buy 5 shirts

Answer:
A) [tex]-\frac{7}{4}[/tex]
Step-by-step explanation:
For this question, we can use the rise over run method, which means y over x.
So count how many it takes for the point on top to get to the bottom by x and y.
It takes 7 spaces down (y) and 4 spaces to the right (x)
So do rise over run and we get
[tex]\frac{7}{4}[/tex]
Meaning that B and C are incorrect. Now what about A and D?
Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.
[tex]-\frac{7}{4}[/tex]
A. is correct.
Is it a function or not a function?
Answer:
not a function

When would you use the vertical line test?
A. to test whether a graph is linear
B. to test whether a graph has an x-intercept
C. to test whether a graph is continuous
D. to test whether a graph represents a function
Answer:
D. to test whether a graph represents a function
Step-by-step explanation:
The vertical line test is used to determine if a graph of a relationship is a function or not.If you can draw any vertical line that intersects more than one point on the relationship, then it is not a function.
Answer:
D. to test whether a graph represents a function

Find the compound interest on 5000 at 12% interest for 15 years.
if the interest is compounded semi-annually.
18000
Step-by-step explanation:
5000*12%= 600 600× 30= 18000 15 years semi annually = 30 x
The compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58
To find the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually, we can use the formula:
A = P(1 + r/n)^(n*t)
where:
P = principal amount = $5,000
r = annual interest rate = 12% = 0.12
n = number of times compounded in a year = 2 (compounded semi-annually)
t = time period in years = 15
A = amount after t years
Plugging in the values, we get:
A = 5000(1 + 0.12/2)^(2*15)= $27,243.58
So, the amount after 15 years is $27,243.58. To find the compound interest, we can subtract the principal amount from the amount after 15 years:
Compound interest = A - P
= $27,243.58 - $5,000
= $22,243.58
Therefore, the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58.

WeMoveU charges an hourly rate for a moving team to load and unload a truck. The charges is a different hourly rate for a team pack and unpack boxes. Use the quotes below to determine the company's hourly rates. Weekday Move: 5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost. Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
Answer:
Step-by-step explanation:
WeMoveU charges an hourly rate for a moving team to load and unload a truck. The charges is a different hourly rate for a team pack and unpack boxes. Use the quotes below to determine the company's hourly rates. Weekday Move: 5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost. Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
Let us represent:
Hours of Loading and Unloading = X
Hours of packing = y
5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost.
5x + 4y = 730..... Equation 1
Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
4x + 5y = 710.... Equation 2
Combining both Equations together
5x + 4y = 730..... Equation 1
4x + 5y = 710.... Equation 2
We solve using Elimination method

Answer:
x = 4 sqrt(5)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + x^2 = 12^2
64+ x^2 =144
Subtract 64 from each side
x^2 = 144-64
x^2 =80
Take the square root of each side
sqrt(x^2) = sqrt(80)
x = sqrt(16*5)
x = 4 sqrt(5)

An iron bar has volume 650 cm' and density 7.87 g/cm3.
Work out the mass of the iron. Give your answer in
a) grams
b) kilograms
Answer:
a.5115.5g
b. 5115.5/1000= 5.1kg
Step-by-step explanation:
Given data
volume= 650 cm^3
density= 7.87 g/cm^3
We know that
density= mass/volume
mass= density*volume
mass= 7.87*650
mass= 5115.5 g
a.5115.5g
b. 5115.5/1000= 5.1kg
