Braxton has money in a savings account. The equation B = 800(1 + 0.03) can be used to calculate the amount
of money in dollars, B. Braxton has in his account after t years since opening the account.
Pam also has money in a savings account. The equation P=800(1 +0.04) can be used to calculate the
amount of money in dollars, P, Pam has in her account after t years since opening the account.
Choose from the drop down menus to correctly complete each sentence.
Braxton's initial investment Choose...
• Pam's initial investment.
The interest on Braxton's account Choose...
• the interest on Pam's account.
Answer:
Braxton's initial investment is equals to (=) Pam's initial investment.
The interest on Braxton's account is less than (< ) the interest on Pam's account.
Step-by-step explanation:
Given - Braxton has money in a savings account. The equation
B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money
in dollars, B, Braxton has in his account after t years since opening
the account.
Pam also has money in a savings account. The equation
P=[tex]800(1 + 0.04)^{t}[/tex] can be used to calculate the amount of money in
dollars, P, Pam has in her account after t years since opening the
account.
To find - Braxton's initial investment ..........Pam's initial investment.
The interest on Braxton's account .....the interest on Pam's account.
Proof -
As given, Broxton equation is - [tex]800(1 + 0.03)^{t}[/tex]
Pam equation is - [tex]800(1 + 0.04)^{t}[/tex]
Now,
1.)
For initial investment , Put t = 0
⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]
P = [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]
As for t = 0
Braxton's equation , B = Pam's equation,P
⇒Braxton's Initial investment = Pam's initial investment.
2.)
For the interest,
As we don not have time for which the interest has to be check.
So , let the time period = 5 years
Therefore,
B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.1593) = 927.42[/tex]
P = [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.2166) = 973.32[/tex]
Now,
Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127
Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173
∴ we get
The interest on Braxton's account is less than the interest on Pam's account.

If the sin 30º = 1/2
then which statement is true? (6 points)
a. cos 150° = 0, because the cosine and sine are supplements
b. cos 60° = 0, because the cosine and sine are complements
c. cos 150° = 1, because the cosine and sine are supplements
d. cos 60° = 1/2, because the cosine and sine are complements
Because sine and cosine are complements, we will have that:
cos(60°) = 1/2.
Which statement is true?First, because cosine and sine are complements, we know that:
cos(x) = sin(x + 90°).
cos(90° - x) = sin(x).
We will use the second relation, with x = 30° we can write:
cos(90° - 30°) = sin(30°)
cos(60°) = sin(30°)
And we know that sin(30°) = 1/2
Then we also have cos(60°) = 1/2.
So the correct option is d.

Nasim is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Nasim's test score (out of 50) if he got 5 questions wrong? What would be his score if he got xx questions wrong?
Answer:
40 or 80%

Answer:
a) (0,0), (-4, 1), (-1,2)b) NoneStep-by-step explanation:
There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.We'll go with the first method. Remember both inequalities should be correct for the same point to accept it as a solution.Given points

Answer:
a. all points are part of the solution set
b. no points are in the solution set
Step-by-step explanation:
Graphs of the two systems of inequalities are attached.
a) The red area on the graph is the solution. The two inequalities can be combined to one compound inequality:
x -1 < y < -1/2x +2
The two boundary lines intersect at x-1 = -1/2x +2 ⇒ x = 2, so there are no points in the solution set with x-values of 2 or greater.
All of the given points are in the solution set.
__
b) The green area of the graph is the solution. Solving each inequality for y gives ...
x -2y ≥ 4 ⇒ 1/2x -2 ≥ y
2x -y ≥ -1 ⇒ 2x +1 ≥ y
The allowed values of y must be less than or equal to the minimum of these limits. The limits have the same value at 1/2x -2 = 2x +1 ⇒ x = -2, so the solution set is the area below and right of that intersection point of the two boundary lines.
None of the given points are in the solution set.

Answer:
3 square root 2.
Step-by-step explanation:
I think the answer is b (3 square root 2). the Pythagorean therom states that B^2+ B^2= C^2. we know that c squared is 36. 3 square root 2 is approximately 4.24. ( this squared is 17.98). 17.98 + 17.98 = 35.96. If i round this up, it is 36.

What is an equation of the line that passes through the points (-6, -2) and
(6,8)?
Answer:
y=5/6x+b
Step-by-step explanation:
use formula (y2-y1)/(x2-x1) to look for the slope:
(8-(-2))/(6-(-6))
=10/12
=5/6 (simplified)
then, use the formula y=mx+b to get the equation by substituting m and x, y to either (-6, -2) or (6, 8):
8=5/6(6)+b
8=5+b
3=b (subtract 5 on both sides)
equation:
y=5/6x+3

Question 20:- Fahein is interested in purchasing an AC too. He will give three times more points to energy efficiency and two points more to noise levels than sevices and installation. Whereas, design features don't matter to him. In this case he devises a way to compare the 5 models. Which one is the correct formula given his preferences?
Answer:
[tex]Total = 3E + 2N + S[/tex]
Step-by-step explanation:
Given
Represent
Efficiency with E; Noise Level with N
and Service and Installations with S
Required
Determine the correct formula
From the question
3 points goes to E: i.e. 3E
2 points goes to N: i.e. 2N
The above is the number of points more than service and installations.
So 1 point will be given to S i.e. S
The total or formula is:

The measure of Angle 1 is 35º and it is complementary to Angle 2. The
measure of Angle 2 is 5x. What is the value of x?
Answer:
x = 11
Step-by-step explanation:
35 + 5x = 90 {Complementary angles}
Subtract 35 from both sides
5x = 90 - 35
5x = 55 {Divide both sides by 5}
x = 55/5
x = 11

A pile of sand has a weight of 60 kg
The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of the sand in each bag
Small bag = 2x
Medium bag = 3x
Large bag = 7x
2x + 3x + 7x = 60
12x = 60
x = 60/12
x = 5
Small bag = 2(5) = 10 kg
Medium bag = 3(5) = 15 kg
Large bag = 7(5) = 35 kg
Done.

The slope of the line that passes through the points (9,11) and (3,6) is what?
Answer:y= -5
X=-6
-5/6
Step-by-step explanation:
For the line above, what is the slope? *
Answer: The slope is 2.
Step-by-step explanation:
To get the slope, use this tip: Rise over run
Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.
Answer:
The slope is 2.
Step-by-step explanation:
The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)

Answer:
9[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplify the radicals
[tex]\sqrt{20}[/tex]
= [tex]\sqrt{4(5)}[/tex]
= [tex]\sqrt{4}[/tex] × [tex]\sqrt{5}[/tex]
= 2[tex]\sqrt{5}[/tex]
[tex]\sqrt{45}[/tex]
= [tex]\sqrt{9(5)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{5}[/tex]
= 3[tex]\sqrt{5}[/tex]
Then
3[tex]\sqrt{20}[/tex] + [tex]\sqrt{45}[/tex]
= 3(2[tex]\sqrt{5}[/tex] ) + 3[tex]\sqrt{5}[/tex]
= 6[tex]\sqrt{5}[/tex] + 3[tex]\sqrt{5}[/tex]
= 9[tex]\sqrt{5}[/tex]
