To compare investments, analysts convert monthly, quarterly, semiannual rates to annual rates. If an investment of $100,000 is invested at 4.5% twice a year, compounded semiannually, the growth can be modeled by the equation A(t) = 100,000(1.045)2t. What is the equivalent annual growth rate for this investment (rounded to the nearest hundredth of a percent) and what is it worth (rounded to the nearest thousand dollar) after 15 years?

Find the unit rate and slope of the graph (ignore what I put down)
Answers
Answer:
slope: 5/7
0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714

whats inequalities ?
Answers
Answer:
An equation looks something like this: 4x2=8
In an equation each value on the opposite side of the equal sign is equal unless its unsolved and u need to solve it.
In an inequality, a <, >, ≥ or ≤ separates 2 values that are unequal. < is a less than sign, > is a greater than sign and so on and so forth. An inequality gives all possible answers for an equation. For example 3x+2≤ 8 is showing us that 3x+2 is any value below or equal to 8. ≤ is a less than OR equal too sign.
in the equation 4x-5≤15 the inequality is showing us that 4x-5 is every possible value below or equal to 20. So an answer could be 19, 18, -5, 7 and basically every number below or equal to 20.

The fire department has seen an increase in smoke detector sales since 2015. In 2015,
they sold 350 detectors which is up from the previous year by 105%. How many did they
sell in the previous year?
Answers
Answer:
Step-by-step explanation:
Given the amount of detectors sold in the current year = 350
percent increment = 105%
To get the amount sold the previous year, we will use the expression;
(105% of x) + x = 350
1.05x = 350 + x
1.05x + x = 350
2.05x = 350
x = 350/2.05
x = 170.7
Hence the amount sold the previous year was 170.7 detectors
Last weekend, nina mowed lawns and received $60. This weekend she mowed 6 lawns and received $90. what is the constant of proportionality?
Answers
Answer:
$15
Step-by-step explanation:
It is given that,
Last weekend, Nina mowed 4 lawns and received $60. This weekend she mowed 6 lawns and received $90.
We need to find the constant of proportionality.
First we can find the money received when she mowed 1 lawn for last weekend.
4 lawns = $60
1 lawn = $15
Then, we will find the money received when she mowed 1 lawn for this weekend.
6 lawns = $90
1 lawn = $15
Hence, the constant of proportionalityis $15.

In a two-factor experiment with 2 levels of factor A and 2 levels of factor B, three of the treatment means are essentially identical and one is substantially different from the others. What result(s) would be produced by this pattern of treatment means?a. a main effect for factor Ab. a main effect for factor Bc. an interaction between A and Bd. The pattern would produce main effects for both A and B, and an interaction
Answers
Answer:
The pattern would produce main effects for both A and B, and an interaction
Step-by-step explanation:
When there is a two factor experiment having two types of level of factor A and the two level of factor B also the three of the treatment that are similar and the one is totally distinct from the others
So here the treatment pattern would be the pattern in which the important and main impact would be generated for both A and B and then an interaction
hence, the last option is correct
Do you guys know this.

Answer:
0.77
Step-by-step explanation:
You solve the inner first, then move to the outer.
Plug in x = 20 for g(x) = [tex]\frac{2x+2}{x-6}[/tex]. It should give you [tex]\frac{42}{14}[/tex], which simplifies to 3.
You then need to solve f(x) with the given value from g(x), which is 3.
Plug in x = 3 for the equation [tex]\sqrt{0.4x^2-x}[/tex], and you should get [tex]\sqrt{0.6}[/tex].
The answer is roughly 0.77.

The answer is "[tex]\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] , \left[\begin{array}{c}-6&2&0&1\\\end{array}\right][/tex]"
Step-by-step explanation:
Given value:
[tex]A= \left[\begin{array}{cccc}1&3&5&0\\0&1&4&-2\\\end{array}\right][/tex]
First you find the general Ax = 0 solution for the free variables.
[tex][A \ \ \ 0]= \left[\begin{array}{cccc}1&3&5&0\\0&1&4&-2\\\end{array}\right]\\\\ R_1\to R_1-3R_2\\\\= \left[\begin{array}{ccccc}1&0&-7&6&0\\0&1&4&-2&0\\\end{array}\right][/tex]
Its general solution is:
[tex]x_1 = 7x_3-6x_4,\ \ x_2=-4x_3+2x_4 \ \ with\ \ x_3, and \ x_4\ free. \ So,[/tex]
[tex]x=\left[\begin{array}{c}x_1&x_2&x_3&x_4\\\end{array}\right] = x_3\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] + x_4\left[\begin{array}{c}-6&2&0&1\\\end{array}\right][/tex]
Null A is: [tex]{\left[\begin{array}{c}7&-4&1&0\\\end{array}\right] , \left[\begin{array}{c}-6&2&0&1\\\end{array}\right] }[/tex]
Charlie's utility function is U(A, B) = AB, where A and B are the numbers of apples and bananas, respectively, that he consumes. When Charlie is consuming 20 apples and 80 bananas, if we put apples on the horizontal axis and bananas on the vertical axis, the slope of his indifference curve at his current consumption is:____________a. -8.b. -1/4.c. -20.d. -4.e. -1/8.
Answers
Answer:
D. -4
Step-by-step explanation:
The formula for calculating the slope of his indifference curve at his current consumption is expressed as:
M = -∆y/∆x
∆y is the change in y axis
∆x is the change in x axis
Since apples are put in the horizontal axis, ∆x = 20
Since banana are on the y axis, then ∆y = 80
Substituting the given values into the formula
M = -80/20
M = -8/2
M = -4
Hence the slope of his indifference curve at his current consumption is -4.
Option D is correct.

David made an error when determining the product of (–2.5)(–8.3). Step 1: (–2.5)(–8.3) = (–8.3)(–2.5) Step 2: = (–8.3)(–2) + (–8.3)(–0.5) Step 3: = (–16.6) + (–4.15) Step 4: = –20.75 In which step did David make his first error?
Answers
Answer:
David make his first error at Step 3
Step-by-step explanation:
We need to determine the error David made when finding the product of (-2.5)(-8.3)
He did the following steps
Step 1: (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2: = (–8.3)(–2) + (–8.3)(–0.5)
Step 3: = (–16.6) + (–4.15)
Step 4: = –20.75
David made a mistake in Step 3
When we multiply (-1) with (-1) we get + instead of - sign. The correct step 3 would be:
Step 3: =(16.6)(4.15)
Step 4: =20.75
So, David make his first error at Step 3
An investment portfolio offers a plan that will increase your holdings 30%
half the time, and lose you 20% the other half. Is this a worthwhile
investment for 1) one year, and 2) for the long term?
Answers
Answer:
It is a worthwhile investment for both one year and for the long term.
Step-by-step explanation:
While the investment will obtain in the first half of the year gains of 30%, and in the second half of the year losses by 20%, at the end of the year the benefit obtained by the investment will be greater than 0%. Therefore, both within a year and in the long term, it is a viable and favorable investment, since it will yield positive results at the end of the cycle.
So, for example, an initial investment of $ 100 would operate in the following way:
-First half of the year: 100 x 1.3 = 130
-Second half of the year: 130 - (130 x 0.2) = 104
Thus, at the end of the year a profit of 4% of the initial investment will be obtained.
