Tess, who lives in the United States, is on a trip to Europe. She is going first to Germany, where the currency is the euro
(€), and then to Switzerland, where the currency is the Swiss franc (CHF). As she travels from Germany to Switzerland,she finds that she has the equivalent of $527 remaining in euros, which she wishes to convert to Swiss francs. If, at
the time of Tess's exchanges, the exchange rate of the US dollar to the euro is 1:0.6957 and the exchange rate of the
euro to the Swiss franc is 1:1.4755, how many Swiss francs does she have? Roynd all currencies to two decimal
places.
Answer: 540.96 francs
Step-by-step explanation: Right on Edge2020
Using proportions, it is found that the amount that she has in Swiss francs is given by 540.97.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, she has the equivalent of $527 remaining in euros. Each dollar is worth 0.6957 euros, hence her amount is equivalent to:
$527 x 0.6957 = 366.6339 euros.
Each euro is worth 1.4755 swiss francs, hence her amount is given by:
366.6339 x 1.4755 = 540.97 Swiss francs.

3x-2x+8=12; x=4
Determine if the value of x is a solution to the equation
Step-by-step explanation:
3x - 2x + 8 = 12; x=4
Now, Evaluate the value of x
3(4) - 2(4) + 8 = 12
12 - 8 + 8 = 12
12 + 0 = 12
12 = 12
Find the 10th term of the geometric sequence 8, -24, 72, ...
Step-by-step explanation:
r=-24/8=72/-24=-3
By using this equation:
a(n)=a(1)*r^(n-1)
and we have a(1)=8 , r=-3
a(n)=8*(-3)^(n-1)
a(10)=8*(-3)^(10-1)
=8*(-3)^9

Find the average rate of change for the function, y=x^2+9x, over the interval between x=3 and x=7. Show all work.
Answer:
The rate of change for the given function between x=3 and x=7 is 19
Step-by-step explanation:
Given function is:
[tex]y = x^2+9x[/tex]
Can also be written as:
[tex]f(x) = x^2+9x[/tex]
The rate of change of a function is given by the formula:
[tex]Rate\ of\ change = \frac{f(b)-f(a)}{b-a}[/tex]
In the given question,
We have to find rate of change between 3 and 7
Here
b = 7 and a = 3
WE have to find f(7) and f(3) first
So,
[tex]f(7) = (7)^2+9(7) = 49 + 63 = 112\\f(3) = (3)^2 + 9(3) = 9+27 = 36[/tex]
Putting the values in the formula
[tex]Rate\ of\ change = \frac{112-36}{7-3}\\=\frac{76}{4}\\=19[/tex]
Hence,
The rate of change for the given function between x=3 and x=7 is 19

The graph of F(x), shown below, has the same shape as the graph of
G(X) = x1 - x2, which contains the point (0, 0). Which of the following is the
equation of F(x)?
Answer:
f(x) = x^4-x^2+ 2
option D
Step-by-step explanation:
From the question, we are told that the graph of g(x) contains the point (0,0)
What the graph of f(x) is showing to us is that it is translated 2 units up the vertical axis to get its starting position
What we are saying in essence is that the graph of f(x) and g(x) are similar, but f(x) was formed as a result of applying some transformation to g(x)
The transformation applied on f(x) is that it was moved 2 units upwards from g(x)
Since the translation is in a positive direction
Since the graph was moved up, it means that we added to the output of the graph
So the equation becomes;
f(x) = x^4-x^2+ 2
The population of rabbits on an island is growing exponentially. In the year 1990, the
population of rabbits was 6200, and by 1994 the population had grown to 10800.
Predict the population of rabbits in the year 1998, to the nearest whole number.
Answer:
The approximate population in 1998 is 18,769
Step-by-step explanation:
Here, we want to predict the population
If it follows an exponential pattern, then we have the equation as follows
y = I( 1 + r)^n
Where y is the present year population
I is the initial population which is the population in 1990
r is the growth rate
n is the number of years after 1990
So for 1994, we have
10,800 = 6200(1 + r)^4
divide through by 6,200
That will be
1.74 = (1 + r)^4
we can have this as follows;
ln 1.74 = 4ln (1 + r)
0.554 = 4ln (1+ r)
0.554/4 = ln (1 + r)
1+ r = 1.1485
r = 1.1485 - 1
r = 0.1485
So for 1998, we have
y = 6200(1 + 0.1485)^8
y = 6200(1.1485)^8
y = 18,769
g=xc-y for x? uhm what?

Explain the difference between accuracy and precision.
Answer: Precision is usually used to describe the exact point at which something will happen, whereas accuracy is described to the point of "close" and "around there". Accuracy is much more dependent on what the situation is but you can use precision when talking about anything that has to be exact.

Percent of strikeouts per at-bats is 32%
Given that;Ball strike = 112 times
Total number of ball play = 350 bats
Find:Percent of strikeouts per at-bats
Computation:Percent of strikeouts per at-bats = [Ball strike / Total number of ball play]100
Percent of strikeouts per at-bats = [112 / 350]100

Solve for the y intercept and then for the x intercept .
4x+5y=20
**ALSO DON’T ANSWER IF YOU WONT SHOW YOUR STEPS ****
Answer:
20 is the y-intercept, 0 is the x-intercept.
Step-by-step explanation:
How I learned:
I was taught that the formula is y=ax+b
b is the one without a variable next to it, so 20 is b.
0 is the x intercept because, I don't know how to explain it well, but 0 is the only x value that touches the x line.
The x-intercept and the y-intercept are both the points that touch the x/y line, depending on the equation.
Hope this helped!
(P.S. 0 is always the x-intercept)
