Determine if the relation is a FUNCTION
Explain the reasoning for your response.
Function or not: 1/2 Point
Reasoning: 1/2 Point
Answers
Answer:
Step-by-step explanation:
Not a function. To be a function, it must pass the vertical line test. The x axis can only be used once. You can have more than one Y, but not the X. In this case, the -2(assuming it-2 by going over 2 places to the left) is used more than once.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
here,
let the number of hats be x and y be the number of T-shirts,
According to the question,
y = 3x - - - - (1
And,
5x + 8y = 435
From equation 1
5x + 8{3x} = 435
5x + 24x = 435
29x = 435
x = 15
Now put x in equation -1
y = 3 × 15
y = 45
Thus, the required number of t-shirts and hats is given as, 45 and 15 respectively

The angles from largest to smallest are:
∠A
∠B
∠C
Step-by-step explanation:
We can see in the diagram that
AB = 7
AC = 8
BC = 9
The angles opposite to sides are as follows:
∠A is opposite to BC
∠B is opposite to AC
∠C is opposite to AB
The angle opposite to the largest side of the triangle is the largest and the angle opposite to smallest side of the triangle is the smallest in measurement
Arranging the sides from largest to smallest:
BC, AC, AB
Similarly the angles opposite them will be arranged according to them
∠A, ∠B, ∠C
Hence,
The angles from largest to smallest are:
∠A
∠B
∠C

you deposit $750 in a savings account the earns a 5% annual interest compounded quarterly.
a. write the function that represents the balance after t years.
b. what is the balance of the account after 4 years?
Answers
Answer:
a. [tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
b .$914.85
Step-by-step explanation:
Step one:
given data
principal p=$750
rate= 5%= 0.05
for quarterly compounding n=4
a. the function that represents the balance after t years.
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
b. when t=4
[tex]A = 750(1 + \frac{0.05}{4})^{4*4}\\\\A= 750(1 +0.0125)^{16}\\\\A= 75(1.0125)^{16}\\\\A= 750*1.2198\\\\A=914.85[/tex]
A= $914.85
The function that represents the balance after t years is FV = $750( 1.0125)^4t.
The balance of the account after four years is $914.92.
What is the function that represents the balance after t years?The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate = 5%/4 = 1.25% m = number of compounding = 4 N = number of yearsFV = $750( 1.0125)^4t

Dee's clothing is having a discount of 40% on all shirts. Let x represent the regular price of any shirt in the store. Enter an expression that can be used to find the sale price of any shirt in the store.
Answers
Answer:
C=P-0.4xStep-by-step explanation:
Step one:
we want to find the expression for the cost of any type of shirt for an applied discount of 40%.
let the price of any shirt be P
let the cost of any shirt be x
and also the price after discount applied be C
Step two:
The discount is
=40/100*x
=0.4*x
=0.4x
Hence the cost of the shirt will be the initial cost minus the discount
C=P-0.4x

Debbie estimated that a caterpillar was 4.5 cm long. Later, she found its actual length to be 4.8 cm. Find the percent error.
Answers
Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 4.5cm
Theoretical value = 4.8cm
Substituting into the equation, we have;
[tex] Percent \; error = \frac {4.8 - 4.5 }{ 4.8} *100[/tex]
[tex] Percent \; error = \frac {0.3}{4.8} *100[/tex]
[tex] Percent \; error = 0.0625 *100[/tex]
Percent error = 6.25%

Select the 2 pairs of points so that the line between those points has slope 3/4. There are
2 choices that work!
A.

B.
(6,-1) and (10,2)
C. (1,5) and (4,7)
D.
(0,5) and (-4,2)
E.
(-4,4) and (-1,7)
Answers
Answer:
D.
(0,5) and (-4,2)
E.
(-4,4) and (-1,7)
Step-by-step explanation:
To solve this problem, we apply the slope formula and compare with the known slope to see if the answer tallies;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
A.
(0,5) and (-4,8)
x₁ = 0 y₁ = 5
x₂ = -4 y₂ = 8
Slope = [tex]\frac{8-5}{-4-0}[/tex] = [tex]-\frac{3}{4}[/tex]
B.
(6,-1) and (10,2)
x₁ = 6 y₁ = -1
x₂ = 10 y₂ = 2
Slope = [tex]\frac{10-6}{ 2-(-1)}[/tex] = [tex]\frac{4}{3}[/tex]
C.
(1,5) and (4,7)
x₁ = 1 y₁ = 5
x₂ = 4 y₂ = 7
Slope = [tex]\frac{7-5}{4-1}[/tex] = [tex]\frac{2}{3}[/tex]
D.
(0,5) and (-4,2)
x₁ = 0 y₁ = 5
x₂ = -4 y₂ = 2
Slope = (2-5) / (-4-0) = 3/4
E.
(-4,4) and (-1,7)
x₁ = -4 y₁ = 4
x₂ = -1 y₂ = 7
Slope = [tex]\frac{7-4}{-1-(-4)}[/tex] = [tex]\frac{3}{4}[/tex]

The linear equation is 98 = 50+3t and the no of tomatoes sold is 16.
Given that,
A roadside vegetable stand sells pumpkins for $5 each and tomatoes for $3 each. The total sales on a certain day was $98. And, they sold 10 pumpkins.Here we assume the no of tomatoes sold be t.
Based on the above information, the calculation is as follows:
98 = 50+3t
98 - 50 = 3t
48 = 3t
t = 16
Therefore we can conclude that The linear equation is 98 = 50+3t and the no of tomatoes sold is 16.
