Answer:
-37/5 because you subtrace both y values on the numerator to get 74 and on the bottom you do the same for x and get -10 and then you simplify to get -37/5
integral rational trigonometric
Substitute x = 3 - 2 cos(θ) and dx = 2 sin(θ) dθ (where "sin" = "sen"). So we have
∫ sin(θ) / (3 - 2 cos(θ)) dθ = 1/2 ∫ 1/x dx
= 1/2 ln|x| + C
= 1/2 ln(3 - 2 cos(θ)) + C
(We can remove the absolute value because -1 ≤ cos(θ) ≤ 1, so 1 ≤ 3 - 2 cos(θ) ≤ 5, and |x| = x when x ≥ 0.)
Write an
equation for the line parallel to the given line that contains C.
C(- 4,6); y = 6/7x+6
Answer:
y = 6/7x +3.43
Step-by-step explanation:
Parallel lines have the same slope. To find the equation, you must use the same slope and plug in the coordinates into the y and x of the equation to get 6= (6/7)(-4) +b
You'll get 3.43 (rounded) for b
Then combine it all together to get the answer above! Hope that helps!

Answer:
C. Australia and Antarctica were a single landmass in the past.
Step-by-step explanation:
The most likely explanation for why the fossils of this plant are found on these two continents is that Australia and Antarctica were a single landmass in the past.
This evidence is vastly supported by the theory of plate tectonics originally, the theory of continental drift.
Plate tectonics proposes that all land masses were once joined together as a single supercontinent called Pangaea.
The region of Antartica and Australia were once joined as a single continental mass.
The plant must have developed together at that time.
When the continents moved apart, they still had the fossils.

Julie sent 200 emails last month. This month she sent 40% less. How many
emails did she send this month?
Answer:
She sent 120 emails this month.
Step-by-step explanation:
Multiply 200 by .60 (60 percent) and it will give you 120.
I used 60 instead of 40 because the problem said 40 percent less, NOT 40 percent of 200.

What value of x is in the solution set of 9(2x + 1) < 9x - 18?
A. -4
B. -3
C. -2
D. -1
Answer:
b. -3
Step-by-step explanation:
9(2x+1) < 9x-18
(distribute the 9)
18x+9 <9x-18
(subtract 9 from both sides)
18x<9x-27
(subtract 9x from both sides)
9x<-27
(divide both sides by 9)

Write an equation and solve. You are saving money to buy a new iPad that costs $353. You have saved $225. How much more money do you need to save?
Answer: You have to save $128 more dollars.
Step-by-step explanation: The iPad costs $353 and you already have $225, so to find the answer you have you subtract what you already have from how much it costs. So 353 - 225 = 128. You need to save up $128 more dollars to get the iPad. (I think this is correct, I tried)

find the angle YWX.
Answer:
34
Step-by-step explanation:
9x-28 = 5x-8
4x = 20
x = 5
5 times x(aka 5) minus 8=17
9 times x(aka 5) minus 28=17
17+17
ywx=34
The value of the angle YWX will be 34.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that the two angles ZWY and ZWX are ( 9x - 28 ) and ( 5x - 8 ) respectively,
The angle will be calculated as:-
9x-28 = 5x-8
4x = 20
x = 5
The angle YWX will be the sum of the angles YWZ and XWZ.
YWX = ( 9 x 5) -28 + ( 5 x 5 ) - 8
YWX = 45 - 28 + 25 - 8
YWX = 17 + 17
YWX = 34
Hence, the measure of the angle YWX is 34.

There are 22 students, from which 6 people will be selected to be on a panel. If Allen and Joe are 2 of the 22 students, then what is the probability that neither will be selected to be on the panel?
Round your answer to three decimal places.
==========================================
Explanation:
Let's start off counting the number of ways to form the panel that doesn't have Allen or Joe on it. In other words, both are not on the panel.
There are 22 students, but we want to exclude 2 of them (Allen and Joe) from the panel. So in reality, we only have 20 students to pick from. There are 6 slots to fill.
The first slot has 20 choices
The second slot has 19 choices
The third has 18 choices
And so on. We count our way down until all six slots are filled. We'll have this sequence of six values: 20, 19, 18, 17, 16, 15
They multiply out to 20*19*18*17*16*15 = 27,907,200
This is the number of permutations where we choose 6 from a pool of 20.
With permutations, order matters; however, order doesn't matter on this panel. All we care about is the group overall.
So we must divide by 6! = 6*5*4*3*2*1 = 720 and we get
(27,907,200)/(720) = 38,760
There are 38,760 different combinations, so there are 38,760 different panels where neither Allen nor Joe are selected.
We'll use this later later, so let A = 38,760
------------------------------------------------------
Now onto the next part. We need to count the total number of possible panels, and this time we're including Allen and Joe.
We have our original total of 22 students. There are still 6 seats to fill.
We could follow the same steps as the prior section, but I'll use a different route.
Let n = 22 and r = 6. Plug these values into the nCr combination formula below
[tex]_n C_r = \frac{n!}{r!*(n-r)!}\\\\_{22} C_6 = \frac{22!}{6!*(22-6)!}\\\\_{22} C_6 = \frac{22!}{6!*16!}\\\\_{22} C_6 = \frac{22*21*20*19*18*17*16!}{6!*16!}\\\\_{22} C_6 = \frac{22*21*20*19*18*17}{6!}\\\\_{22} C_6 = \frac{22*21*20*19*18*17}{6*5*4*3*2*1}\\\\_{22} C_6 = \frac{53721360}{720}\\\\_{22} C_6 = 74613\\\\[/tex]
There are exactly 74,613 ways to form a committee of 6 people from a pool of 22 total.
Let B = 74,613
------------------------------------------------------
To find the probability of neither Allen or Joe are on the committee, we divide the values of A and B found earlier
A/B = (38,760)/(74,613) = 0.5194805
This value is approximate.
Rounding to three decimal places, or rounding to the nearest thousandth, leads to the final answer 0.519
There's roughly a 51.9% chance of forming a panel where neither Allen nor Joe are members.

Answer:
You would pay 9 dollars because 4 times 3.5 is 14. If you subtract the 5 dollars from the gift card you're only paying 9 dollars out of pocket

Why is this statement false?
If a number has 2 and 4 as factors, then it has 8 as a factor.
Answer:
It is false
Step-by-step explanation:
It is false because 12 has the factors of 2 and 4 but 8 is not a factor of 12.
The statement is false. If a number has 2 and 4 as factors, it doesn't mean that it has 8 as a factor.
The fact that a number has 2 and 4 as factors, doesn't mean that the number will have 8 as a factor. For example, 4 and 12 have both 2 and 4 as factors but don't have 8 as a factor
Factors of 4 = 1, 2 and 4.Factors of 12 = 1, 2, 3, 4, 6 and 12.Therefore, the fact that a number has 2 and 4 as factors doesn't mean that it has 8 as a factor.
