A roller coaster is being designed that starts at (0,22) and ends at (19,2),
Along the ride there is a relative minimum at (5,6) and a relative
maximum at (10,18). The roller coaster is almost finished but one
section is missing. Find the correct function that completes the roller
coaster so that the ride is smooth and continuous.
Answer:
The function is, f(x) = 6·sin((π/5)(x + 3π/2)) + 12
Step-by-step explanation:
The general form of equation of a roller coaster is given as follows;
y = A·sin(B(x - C)) + D
Where;
A = The amplitude = (18 - 6)/2 = 6
D = The vertical shift = 12
One revolution = 10 unit
∴2·π = 10 unit
Therefore, 10 = 2·π/B
B = 2·π/10
The phase shift = 3·π/2
Therefore, we have the function as follows;
f(x) = 6·sin(2·π/10(x + 3π/2)) + 12 = 6·sin((π/5)(x + 3π/2)) + 12

Order the sides of each triangle from shortest to longest.
Answer:
FG, GH, FH
Step-by-step explanation:
H=180-100-50=30°
Since H is the smallest degree, the side opposite it (FG) is the shortest length.
Since F is the middle degree, the side opposite it (GH) would be the middle length.
Since G is the highest degree, the side opposite it (FH) would be the longest.
FG, GH, FH

Find (g o f)(5)
Answer:
(g o f)(5) = 47
Step-by-step explanation:
We are given a composite function:
g(x) = 4x + 3
f(x) = 3x - 4
We are supposed to find (g o f)(5), which really means g( f(x) ). So, we put the function of f(x) for every x in g(x), like this:
g(x) = 4x + 3
g( f(x) ) = 4(3x - 4) + 3
g( f(x) ) = 12x - 16 + 3
g( f(x) ) = 12x - 13
Now, we also need to evaluate for x = 5, like this:
g( f(5) ) = 12(5) - 13
g( f(5) ) = 47

What is the total surface area of the rectangular prism?
Answer:
286.5
Step-by-step explanation:
(3 x 7.5) x 2 = 45
(11.5 x 3) x 2 = 69
(11.5 x 7.5) x 2 = 172.5
45 + 69 + 172.5 = 286.5

Enter your answer as a fraction or a mixed number.
Answer:
Part A: Choice 3) Reasonable. The grapes and apples is about 2 cups and pears and oranges is exactly 3 cups.
Part B: Exactly 4 11/12 cups
almost equal to 5 cups
Step-by-step explanation:
The missing part of the question is :
2 1/2 cups of pears. 2/3 cup of grapes 1 1/4 cups of apples 1/2 of orange slices .
Pears + apples
2 1/2+1 1/4 =
5/2 + 5/4
= 10+5/4
= 15/4
= 3 3/4 cups
Reasonable. The pears and apples is about 3 cups and the grapes
and oranges is exactly 2 cups. This statement is wrong.
Grapes and oranges
2/3 + 1/2
= 4+3/6
=7/6
=1 1/6 cups
grapes and apples
2/3 cup of grapes 1 1/4 cups of apples
2/3 + 5/4
= 8+15/12
= 23/12
= 1 11/12 cups
pears and oranges
2 1/2 cups +1/2 of orange slices
3 cups
Reasonable. The grapes and apples is about 2 cups and pears and
oranges is exactly 3 cups. this statement is true as shown above.
N.B the answer may vary due to the different measurements given in the missing part of the question.
Part B:
grapes and apples + pears and oranges
1 11/12 cups +3 cups
= 23/12+ 36/12
= 59/12
= 4 11/12 cups

What is the median of the data set?
9
8.5
8
10
Answer:
8.5
Step-by-step explanation:
When you write out the data set, it looks like this:
5, 8, 8, 8, 8, 9, 9, 9, 10, 10
The median means the exact middle of the data set. In this case, it falls between the 8 and the 9, so the middle would be 8.5, so that's the median of the set. I hope this helps :)
Answer:
The median is 8.5
Step-by-step explanation:
The median is the middle number in a data set. For example, if you had a data set:
2, 2, 3, 4, 4
You would go forwards and backwards in the set until you found the middle number, which is 3. 3 would be the median.
However, if there is no middle number (there are an even number of points in the set), you add the two remaining numbers and divide it by two.
For example, if the final two numbers were:
2, 6
You would add 2 and 6 to get 8, and divide by 2, and you get the median 4.
In this set, we have
5, 8, 8, 8, 8, 9, 9, 9, 10, 10.
The final two numbers are 8 and 9, so you add 8+9=17, divided by 2 = 8.5.

Kim bought a lawn chair that had a ticket price of $25.00. She ended up paying $26.50 after tax. If she were to buy a $40.00 patio table, how much would she have to pay after tax?
Answer:
41.50
Step-by-step explanation:
you would have to minus the 26.50 and 25.00 and then you would get 1.5 so that's how much the tax is. you would still keep the zero tho bc if there is nothing after the 5 u add zero.

The Chemistry Club is experimenting with different mixtures of water with a
certain chemical to make fake snow.
To make each mixture, the students start with some amount of water, and then add
1/7 of that amount of the chemical, and then 9 more grams of the chemical. The
chemical is expensive, so there can't be more than a certain number of grams of the
chemical in any one mixture. How much water can you start with so that you don't
use up too much of the chemical?
a. 1/7x + 9 < 26.25
b. 9x + 1/7 s 26.25
26.25x + 9 = 1/7
C.
d. 1/7x + 26.25 39
Answer:
Suppose we have with x, the amount of water we use (in grams).
1/7 of this will be the chemical, then we have (1/7)*x grams of chemical.
Then we add another 9g of the chemical, then we have in total:
(1/7)*x + 9g of the chemical.
And we know that the chemical is expensive, so there can't be more than a given number of grams of the chemical, because of the phrase:
"...There can't be more than..."
We will have a relation like:
(1/7)*x + 9g ≤ something.
By looking at the options, we can see that "something" = 26.25 grams
then we will have the inequality:
(1/7)*x + 9g ≤ 26.25 g
Now we can solve this for x, the amount of water used:
(1/7)*x ≤ 26.25 g - 9g
x ≤ (26.25 g - 9g)*7
x ≤ 120.75 grams
This means that the maximum amount of water we can use is 120.75 grams of water.
