Answer:
c
Step-by-step explanation:
The graph starts at 100 and decreases as it goes the following situations that were listed should be somewhat implying that something is decreasing. Since a and b are GAINING something then it can't be that because it is increasing, so we are left with choice c.

If f={(-1,-3), (1,1),(2,3),(4,6)} and g={(-1,-1),(1,7),(4,3)} what is (f+g)(4)?
Answer:
(f + g)(4) = 9
Step-by-step explanation:
We have that:
f = {(-1,-3), (1,1),(2,3),(4,6)}
this means that:
f(-1) = -3
f(1) = 1
f(2) = 3
f(4) = 6
and we also know that:
g = {(-1,-1),(1,7),(4,3)}
hich means that:
g(-1) = -1
g(1) = 7
g(4) = 3
Now we want to find:
(f + g)(4)
For the general case of two functions f(x) and g(x)
(f + g)(x) = f(x) + g(x)
Then:
(f + g)(4) = f(4) + g(4)
and we know both of these values, so we can just replace them:
(f + g)(4) = f(4) + g(4) = 6 + 3 = 9
Then we get:
(f + g)(4) = 9

Find the are of shape?
Answer:
240 ft²
Step-by-step explanation:
The shape is composed of a rectangle and a triangle.
The area of the shape = area of the triangle + area of the rectangle
= ½*bh + L*W
Where,
b = base of triangle = 24 ft
h = height of triangle = 12 - 8 = 4 ft
L = length of rectangle = 24 ft
W = width of rectangle = 8 ft
Plug in the values into the equation
Area of the shape = ½*24*4 + 24*8
= 48 + 192
= 240 ft²

Convert the given base ten numeral into a numeral in base two.
9514 1404 393
Answer:
101000₂
Step-by-step explanation:
The usual place-value rules apply. Bit positions have values that increase by a factor of 2 as you go leftward from the units bit.
40 = 32 + 8 = 2⁵ +2³ = 101000₂
_____
The usual conversion algorithm has you repeatedly divide the number by 2. The remainder at each step is the binary digit (bit) next to the left. The first remainder is the units bit.
40/2 = 20r0
20/2 = 10r0
10/2 = 5r0
5/2= 2r1
2/2 = 1r0
1/2 = 0r1
The bits left to right are the remainders from the bottom up: 101000.
__
Additional comment
Along the same lines, a fraction can be converted to a binary fraction by repeatedly multiplying by 2. If the result is 1+(something), the fraction bit is 1. Otherwise it is 0. The next step repeats with the fractional part of that result. This develops the fraction bits left to right.
Example:
1/16 × 2 = 1/8 + 0
1/8 × 2 = 1/4 + 0
1/4 × 2 = 1/2 + 0
1/2 × 2 = 0 +1
The binary equivalent of 1/16 is 0.0001₂.
__
Fractions that do not have denominators that are a power of 2 will be repeating binary fractions. Of course, irrational numbers will have non-repeating binary fractions.

Step-by-step explanation:
Area of a triangle is base times height
We have a base made by point m and n with a length of 6
now the third point has to form a height which when put with the base, gets you 18
area of triangle is bh/2
so lets set height as h, 6x/2 = 18 6x = 36 x = 6
This means the point has to be 6 apart either left or right. Only point that matches this is a.

Dina invests $600 for 5 years at a rate of 2% per year compound interest.
Calculate the value of this investment at the end of the 5 years,
Answer:
The investment after 5 years is $ 662.45.
Step-by-step explanation:
Principal, P = $ 600
Time, t = 5 years
Rate of interest, R = 2 %
Time , t = 5 years
The amount after the time 5 years is
[tex]A = P \times \left ( 1+\frac{R}{100} \right )^t\\\\A = 600\left ( 1+0.02 \right )^5\\\\A = 662.45[/tex]
So, the investment after 5 years is $ 662.45.

The lines below are perpendicular. If the slope of the green line is -1/6, what is the slope of the red line?
Answer:
slope of red line=6
Step-by-step explanation:
Hi there!
We're given a set of perpendicular lines and the slope of the green line being -1/6
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
So to find the slope of the red line, we can use this formula (m is the slope):
-1/6m=-1
Multiply both sides by -6 (clears the fraction to get 1m on the left)
m=6
So the slope of the red line is 6

reflection across y=-1
Answer:
I'm not graphing, but I can describe the reflection as R', S', T', U':
R' = (-3, 1)
S' = (-2, 0)
T' = (-1, 2)
U' = (-2, 2)
Step-by-step explanation:
y = -1 is the line one unit below the x axis (the x axis is y=0).
To reflect any point across y=-1, we just need to leave the x coordinate as was, but the (new y) will be -2-(old y)
R = (-3, -3), R' = (-3, -2+3) = (-3, 1)
S = (-2, -2), S' = (-2, -2+2) = (-2, 0)
T = (-1, -4), T' = (-1, -2+4) = (-1, 2)
U = (-2, -4), U' = (-2, -2+4) = (-2, 2)

A computer professor is interested in studying the amount of time it would take students enrolled in the Introduction to Computers course to write and run a program in Matlab. The professor hires you to analyze the following results in minutes from a random sample of 9 students:

Required:
At the 0.05 level of significance, is there evidence that the population average time is greater than 10 minutes?
Answer:
Following are the solution to the given question:
Step-by-step explanation:
In this question, firstly we calculating the [tex]\bar{x} \ \ and \ \ s[/tex]
[tex]\bar{x}=11.89 \\\\s = 2.52\\\\n = 9\\\\\alpha=0.05\\[/tex]
[tex]H_0 : u \leq 10\\\\ H_1 : u > 10[/tex]
It is an upper test and testing the statistics:
[tex]t=\frac{\bar{x}-\mu }{\frac{s}{\sqrt{n}}}\\\\t=\frac{11.89-10 }{\frac{2.52}{\sqrt{9}}}\\\\t=2.25\\\\[/tex]
So, the test statistics [tex]t=2.25[/tex]
[tex]\alpha=0.05 \\\\ d.f = n-1\\\\[/tex]
[tex]=9-1\\\\=8[/tex]
critical value =2.306 ( using t-table ) [tex]critical\ value >\ test\ statistics , \ Fail\ to\ Reject\ H_0[/tex]
Decision: We should not reject the null hypothesis.
