Answer:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49
Step-by-step explanation:
Given that:
Initial investment made, 8 years ago = $1000
Depreciation value each year = 15%
To find:
a. Multiplier
b. Function [tex]f(t)[/tex] to describe the situation.
c. Worth of stock now.
Solution:
a. Depreciation of 15% means the value becomes (100 - 15) % = 85% or 0.85 of the actual value.
Therefore, the multiplier is 0.85.
b.
Every year the value becomes 0.85 times of the actual value.
If it continues for [tex]t[/tex] years, then the values will be:
[tex]f(t) =1000(0.85)^t[/tex]
c. Let us put [tex]t=8 \ years[/tex] to find the worth of stock now.
[tex]\Rightarrow f(8) =1000(0.85)^8\\\Rightarrow \bold{\$272.49}[/tex]
So, the answers are:
a. 0.85
b. [tex]f(t) =1000(0.85)^t[/tex]
c. $272.49
Which set of ordered pairs represents a function?
A {(1,1),(5, -9), (1,7), (8, -4)}
B {(-9, -1),(-9,5), (9,6), (-7,7)}
C {(-7,7), (1, -9), (6, 7), (-1,3)}
D {(-7, -6),(-4,2), (-7, -9), (1, -6)}
Answer:
C
Step-by-step explanation:
The easiest way to solve these problems is usually to just look at the x values and see if any of them appear more than once. If you have 2 or more of the same x value in one set, it isn't a function. If every x value is different, it is a function

Answer:
ik that angle one would be the same as 3 and 2 and 4 are also the same so if u find an answer for 2 or 4 they would be the same but is there like a total of the entire thing
Answer:
Angle 1 = 72 degrees
Angle 2 = 110 degrees
Angle 4 = 110 degrees
Step-by-step explanation:
Use angle rules.
Angle 2 + angle 3 = 180, because they supplementary angles. Therefore, to find angle 2, you can do 180 - 72 = 110 degrees.
Angle 1 and angle 3 are vertical angles, meaning they are equal. Thus, angle 1 = 72 degrees.
Angle 2 and 4 are vertical angles, meaning they are equal. Thus, angle 4 = 110 degrees.

Jezebel is planning a party at the skating rink. The cost for each person attending is $3.50 for skate rental and $5.00 for food. Jezebel cannot spend more than $300. Which inequality could be used to find the greatest number of people, p, that can attend?
Answer:
The inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.
Step-by-step explanation:
From the information provided, you can write an inequality where total cost for people attending at the party should be less than or equal to $300:
3.50p+5.00p≤300
8.50p≤300
Now, you can solve for p:
p≤300/8.50
p≤35
According to this, the answer is that the inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

This is the table of values of a function. Write the output when the input is n.
Input= 4 6 9 n
Output= 2 4 7 ?
Answer:
n-2
Step-by-step explanation:
1. Find what has been done to the input value to give the output value. Here, we can see that each input value is two more than each output value, so two has been subtracted from each input value to give the output. This means that the rule for this function is: take the input value and subtract two.
2. Express this in terms of n. We can then express this in terms of n (using n to show the rule that we have found). Since n is the input value we have, to find the output when the input is n, we subtract two from n. This gives us our answer of n-2.
Netflix used to charge $5 per DVD rental and a $10 membership fee. Plex used to charge $2 per DVD and a $60 membership fee. Which inequality best represents when the charges from Netflix are less than Plex?

There are 3 consecutive integers. If the smallest one is n, find the sum of 3 integers.
Answer:
3n + 3Step-by-step explanation:
The consecutive integers are increasing by 1
n ← the smallest integer
n+1 ← the middle integer
n+1+1 = n+2 ← the largest integer
The sum:
S = n + n+1 + n+2
S = 3n + 3
The model shows the expression 21 + 9.

Triangle EFG has vertices E(-3,1), F(1,1), and G (4,5). Find the coordinates of the image of point F after a reflection across the x-axis.
Answer:
(1,-1)
Step-by-step explanation:
the coordinates of the image of point F after a reflection across the x-axis is (1,-1).
What is reflection?In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyper plane as a set of fixed.
Here, given that,
Triangle EFG has vertices E(-3,1), F(1,1), and G (4,5).
We have to find the coordinates of the image of point F after a reflection across the x-axis.
Now, we know that,
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
Hence, the coordinates of the image of point F after a reflection across the x-axis is (1,-1).

A function assigns the value of each element of one set to the other specific element of another set. The value of f(8) is 5.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The function that is given is mentioned below. Now, the value of the function can be found as shown below.
A.) f(-10)=?
When the value x is -10, it will lie in the first category of the function, therefore, the function for this value of x will be,
[tex]f(x) = 2x+1\\\\f(-10) = 2(-10)+1\\\\f(-10) = -20+1 = -19[/tex]
B.) f(2) = ?
When the value x is 2, it will lie in the second category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x^2\\\\f(2) = 2^2 = 4[/tex]
C.) f(-5)=?
When the value x is -5, it will lie in the first category of the function, therefore, the function for this value of x will be,
[tex]f(x) = 2x+1\\\\f(-5) = 2(-5)+1\\\\f(-5) = -10+1 = -9[/tex]
D.) f(-1)=?
When the value x is -1, it will lie in the second category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x^2\\\\f(-1) = (-1)^2 = 1[/tex]
E.) f(8)=?
When the value x is 8, it will lie in the third category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x-3\\\\f(8) = 8-3 = 5[/tex]
