A.pex VLS Algebra 1: 6.2.4 Practice - HELP NEEDED!!!
The file below is a picture of the problem I'm stuck on... it's hard to explain. I found Coin A and Coin C, but Coin B is confusing me.
Equations to find the value:
Coin A: V=25(1.07)^t
Coin B: V=40(1.05)^t
Coin C: V=60(1.04)^t
V represents the coin's value and t represents what year it is (kind of).
Please help! Even if you can't do the problem, if you explain how to do it to find Coin B, that would be so appreciated! If you are confused about anything, I'll be happy to explain! Thank you!
Answers
Answer:
Answer:1.) I chose coin A and B
2.) Coin: B Value: $40 Annual rate: %5
Coin: A Value: $25 Annual rate: %7
3.) Coin: A P: 25 R: 1.07 Function: v = 25(1.07)^t
Coin: B P: 40 R: 1.05 Function: v = 40(1.05)^t
4.) Base: 1+r Initial: P Exponent: t
If R increased, then P would also increase because you must distribute, and you would be distributing R into P there for if R changes then so would P.
5.) Coin A: Initial value: $25 10 years: $25.70 20 Years: $26.40 30 years: $27.10 60 years: $29.20
Coin B: Initial value: $40 10 years: $40.50 20 years: $41 30 years: $41.50 60 years: $43
Coin C: Initial value: $60 10 years: $60.40 20 years: $60.80 30 years: $61.50 60 years: $62.40
6.) Coin A because the value goes up the most and I probably wouldn't be able to keep the coin for more than 60 years because I would lose it.

The way I learned it was that if they dont have the same variables dont touch them, so what I did was multiply the like numbers (2 and 5). Why are they alike? Because they don't have a variable! I then just put the X sign there to show that there is no other way to multiply this. If it where addition, it would be 10+a so that would equal 10a.

how to draw angle of 135 degree
Answers
Answer:
So draw a straight line. This measures as 180 degrees on your protractor. Align your protractor to the straight line, with the circle point in the middle of the line and notice the labels on the side. One of them, between 90 and 180 on the outer scale will measure as 135. Mark this on top of the paper, and remove the protractor. When you remove it, extend your mark to the middle of your line, and this gives you an obtuse angle of 135 degrees. Be sure to recheck!

If a factory can produce 410 sandwiches in 1 hour, how many sandwiches will it produce in 5 hours?
Answers
The answer is 2050 I believe
Every hour the factory makes 410 sandwiches so if we multiply this by 5 we should get our answer
410 x 1= 410
410 x 2= 820
410 x 3= 1230
410 x 4= 1640
410 x 5= 2050
Explain why the function of f(x)=4x^2+8x is neither even or odd
Answers
Answer:
By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Step-by-step explanation:
We need to explain why the function of [tex]f(x)=4x^2+8x[/tex] is neither even or odd
First we will understand, when the function is even and odd
Even function:
A function is even if f(-x) = f(x)
Odd function:
A function is odd if f(-x) = -f(x)
So, if we get the above result by putting x = -x, then we can say that the function is even or odd.
If we don't get any of the above results then the function is neither even nor odd.
So, for the given function: [tex]f(x)=4x^2+8x[/tex]
Put x = -x
[tex]f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x[/tex]
So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Brody and Carrie like to hike in the mountains. From the trailhead, they climb 103 feet until they reach a waterfall. On the next part of the trail, they descend 84 feet. To reach their destination, Brody and Carrie must then climb another 194 feet. Their destination is 734 feet above sea level. At what elevation is the trailhead?
Answers
Answer:
521 feet.
Step-by-step explanation:
In the given question, the number of feet covered with respect to climbing would have a positive value. While the number of feet descended would have negative value.
The total feet covered by Brody and Carrie, with the elevation of the trail-head should be equal to the elevation of their destination above sea level.
To determine the elevation of the trail-head, let its elevation be represented by h.
So that,
h + 103 - 84 + 194 = 734
h + 297 - 84 = 734
h + 213 = 734
h = 734 - 213
h = 521
h = 521 feet
The elevation of the tail-head is 521 feet.

x = 11, ∠ 2 = 146°
Step-by-step explanation:
∠ 2 and 146° are corresponding angles and are congruent, then
∠ 2 = 146°
Thus
13x + 3 = 146 ( subtract 3 from both sides )
13x = 143 ( divide both sides by 13 )
x = 11

Wyatt buys a one-quart bottle of juice for $4.80. What is the unit rate of the cost of
the juice per fluid ounce?
Answers
Answer:
Unit rate per fluid ounce = $0.15
Step-by-step explanation:
Given that:
Cost of one quart bottle of juice = $4.80
We know that:
One quart = 32 ounces
Unit rate is the rate in which two quantities are compared and one of them is one.
Unit rate = [tex]\frac{4.80}{32}[/tex]
Unit rate = $0.15 per fluid ounce
Hence,
Unit rate per fluid ounce = $0.15

Second, if the graph intercepts the line more than two points then it won't be a function.
If the graph only intercepts the line only once (one point) then It is a function.
From the graph, It is a function.

The slope is 2
Step-by-step explanation:
Pick two points and plug into this equation: y2-y1/x2-x1
(-3,2) and (-1,6)
2-6/-3-(-1)=-4/-2= 2
Answer:
The slope of the linear function is 2
Step-by-step explanation:
Calculating the Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The table shows four points: (-3,2), (-1,6), (1,10), and (3,14). To find the slope on the line passing through them we only need two, for example (-3,2), (-1,6):
[tex]\displaystyle m=\frac{6-2}{-1+3}[/tex]
[tex]\displaystyle m=\frac{4}{2}=2[/tex]
Any other pair of points should give the very same value for the slope. Use (1,10), and (3,14):
[tex]\displaystyle m=\frac{14-10}{3-1}[/tex]
[tex]\displaystyle m=\frac{4}{2}=2[/tex]
Thus, the slope of the linear function is 2
