Answer:
-4arccos(x^(1/4)) +C
Step-by-step explanation:
My machine solver gives an answer that reduces to the expression ...
-4arccos(x^(1/4)) +C
__
We know that ...
(d/dx)arccos(x) = -1/√(1-x²)
If you let u = x^(1/4), then you can make the integrand look something like ...
4 du/√(1 -u²)
which is what you need to get to the arccos function.

The spinner is spun 75 times.
A spinner has 4 sections labeled A, B, C, D. D is 75 percent, A is 25 percent, and B and C are both around 12.5 percent.
What is the experimental probability of spinning an "A" ? Round your answer to the nearest hundredth if necessary.

The frequency for A is given as 20, this means A was spun 20 out of 75 spins.
20/75 = 0.2666 which rounds to 0.27
The answer is 0.27
We will see that the experimental probability is P = 0.27, so the correct option is c.
What is the experimental probability of spinning an "A" ?The experimental probability of the outcome A is equal to the quotient between the number of times that the outcome was A and the total number of times that the experiment was performed.
Here we know that the experiment was performed 75 times, and 20 of these 75 times, the outcome was A, then the experimental probability is:
P = 20/75 = 0.27
So the correct option is c.

When the two crews start working together, what part of all the garbage bins will the first garbage truck empty
Complete question is;
The city just assigned a second garbage truck to empty the bins in Kat’s neighborhood on trash day. The crew from the first garbage truck used to empty all the bins by themselves in 5 hours. In their training, it took the crew from the second garbage truck 8 hours to empty all the bins. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? To the nearest tenth, the first garbage truck will empty about of all the bins.
Answer:
Part of all bins first garbage truck will empty = 0.6
Step-by-step explanation:
Let the total number of bins emptied be denoted by n.
We are told that the crew from the first garbage truck empties all the bins in 5 hours. Thus
Work rate = (n/5) bins/hr
We are told the second garbage truck empties in 8 hours. Thus;
Work rate = (n/8) bins/hr
When both garbage trucks work together, the total amount of time spent will be denoted by x. Thus;
((n/5) + (n/8))x = n
Divide through by n to get;
x/5 + x/8 = 1
Multiply through by 40 to gwt;
8x + 5x = 40
13x = 40
x = 40/13 hrs
To find the part of all the garbage bins the first garbage truck empty when they work together, we will simply multiply the value of x by the work rate of the first garbage truck. Thus;
Part = (n/5) × (40/13)
Part = (40/65)n = 0.615 of n
To the nearest tenth gives 0.6 of n

An ice chest contains 2 bottles of orange juice,
5 bottles of grape juice, and 1 bottle of apple
juice, all buried in ice. What's the probability
of pulling out a bottle of orange juice and then
a bottle of grape juice?
Answer:
5/28
Step-by-step explanation:
P(oj, then grape) = 2/8 x 5/7 = 10/56 = 5/28
The probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
An ice chest contains 2 bottles of orange juice, 5 bottles of grape juice, and 1 bottle of apple juice, all buried in ice.
The probability of pulling out a bottle of orange juice and then a bottle of grape juice is calculated as below:-
Probability = Number of favorable outcomes / Number of sample
P(orange , then grape) = 2/8 x 5/7 = 10/56 = 5/28
Therefore, the probability of pulling out a bottle of orange juice and then a bottle of grape juice is 5/28.

On its first play of the game, a football team gained 6 yards. On its next
team lost 2 yards and then gained 7 yards. Use integers to describe these three plays.
What integer represents a play in which the team neither gains yards nor loses yards?
A play that gains yards would be represented by a
integer
A play that loses yards would be represented by a
integer.
On the first play, the team gained
yards.
A gain of 6 yards is represented by the integer
On the second play, the team lost
yards.
A loss of 2 yards is represented by the integer
On the third play, the team gained
yards.
A gain of 7 yards is represented by the integer
The three plays can be described by the integers
and
It shows your screenshot, but I've filled in the blanks with the answers.
====================================================
Explanation:
Positive integers represent yards that the team gains. On the opposite side, negative integers represent yards the team loses.
For example, if a team gains 3 yards, then we write that as +3 or simply 3. If a team loses 5 yards, then we write -5. Adding 3 to -5 gets us 3+(-5) = -2 showing the overall result is a loss of 2 yards at the end of the second down.
As another example, if a team gains 7 yards on first down, but then loses those 7 yards on second down, then they gained overall 7+(-7) = 0 yards overall. They haven't gone anywhere at the end of the second down.
We could do things the other way around like this. Suppose the team loses 8 yards on first down, but has better luck on second down to gain 8 yards. They get back to the original line of scrimmage (back to the starting point) and we can say -8+8 = 0. The team hasn't gone anywhere, but it could be worse and they could be dealing with a loss of yardage.
It might help to set up a vertical number line to help try to visualize negative numbers. Each gain means you go upward. Each loss means you go downward. In a sense, it's like a skyscraper and each integer represents floors of the building. Negative integers are basement floors. Zero is the ground level.
How many different triangles can you make if you are
given these three lengths for sides?
17 cm
13cm
23cm
Answer:
1 triangle can be formed
We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;
17 + 23 > 13
17 + 13 > 23
23 + 13 > 17
Since the above conditions are met, then we can form one triangle.
Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.
SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
Thus, only 1 triangle can be formed.

The solid below was made by cutting a cone-shaped hole out of a cylinder. The surface area of the resulting composite solid is square cm. Write your answer in terms of pi.
*see attachement below for the diagram
Answer:
(252π + 20) cm²
Step-by-step explanation:
The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)
✔️Curved surface area of cylinder = 2πrh
r = ½(12) = 6 cm
h = 18 cm
C.S.A = 2*π*6*18 = 216π cm²
✔️Area of 1 base = πr²
r = ½(12) = 6 cm
Area = π*6²
Area = 36π
✔️Slant height of the cone = 10 cm
✅The surface area of the resulting solid = 216π + 36π + 2(10)
= (252π + 20) cm²
