Answer: The answer is true.
Use the given substitution and the chain rule to find
dy/dx
y=cos (6x - 5), u = 6x-5
Substituting u = 6x - 5, you write
y = cos(u)
Then differentiating with the chain rule gives
dy/dx = dy/du • du/dx
We have
dy/du = -sin(u)
du/dx = 6
so
dy/dx = -6 sin(u) = -6 sin(6x - 5)

A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What equation represents the length of the third side if the second side is length s?
2s - 10
2s + 10
s - 10
s + 10
Answer:
side - equation - measurement
1st side - 2s - 65 - 55cm
2nd side - s - 60cm
3rd side - s - 10 - 50cm
Step-by-step explanation:
total = 165
side - s
1st side = 2s - 65
2nd side = s
3rd side = s - 10
1st side + second side + 3rd side = 165
2s - 65 + s + s - 10 = 165
2s + s + s - 65 - 10 = 165
4s - 75 = 165
4s = 165+ 75
4s = 240
s = 60
1st side = 2s - 65
= 2(60) - 65
= 120 - 65
= 55cm
2nd side = s
= 60cm
3rd side = s - 10
= 60 - 10
= 50cm
3rd side is represented by s - 10 as it is less than the second side by 10cm hence taking away the 10 from the side forming the equation s - 10
Answer:
s-10

For a fairground ride the maximum weight of a person is 100kg to the nearest kg.
What is the maximum a person can weigh to go on the ride safely
Answer:
The maximum a person can weigh to go on the ride safely is 100.5 kg
Step-by-step explanation:
The specification for the maximum weight of each person that goes on the ride = 100 kg
Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;
[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg
A free cable sparkling juice calls for 1 1/2 quarters of sparkling water and 3/4 course with grape juice how many sparkling how much sparkling water would you need to mix with 9 quarts of grape juice
Answer: 18 quarts
Step-by-step explanation:
As per given,
Quantity of sparkling juice is proportional to quantity of course with grape juice.
Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .
Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.
then, by equation of direct proportion , we have
[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]
Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts

a = 6x-11
g= 36
n = 7x - 27
Solve for x
Answer:
6x - 11 + 7x - 27 = 36
6x + 7x = 13x
-11 + (-27) = -38
13x - 38 = 36
-38 - 36 = -74
13x/13 = -74/13
x = -74/13

5x+4y=116 10x+6y=204 solve for x and y
Answer:
x = 12
y = 14
Step-by-step explanation:
5x + 4y = 116
5 x 12 = 60
4 x 14 = 56
60 + 56 = 116
10x + 6y = 204
10 x 12 = 120
6 x 14 = 84
120 + 84 = 204
-------------------------------------------
Here's how I found x and y:
10x + 6y = 204 can be divided by 2
5x + 3y = 102
Then I took 116 and subtracted 116 given the difference
in y.
116 - 102 = 14
So y = 14 and then I sovled for x:
5x + 56 = 116
116 - 56 = 60
60/5 = 12
10x + 84 = 204
204 - 84 = 120
120/10 = 12

I NEED HELP NOW !!!!!!! In order for each sheep to get enough grass to eat, there should be 7 sheep for each acre of land. Which farm has the correct ratio of sheep to acres? Select the best answer from the choices provided. A. The Twelve Oaks farm has 14 sheep and 2 acres of land. B. The Tara farm has 28 sheep and 3 acres of land. C. The Butler farm has 35 sheep and 6 acres of land. D. The Scarlett farm has 21 sheep and 2 acres of land. 10 POINTS
Answer:
A: The Twelve Oaks farm has 14 sheep and 2 acres of land.
Step-by-step explanation:
For every 7 sheep, there has to be one acre of land. In order for you to find how many sheep are needed for each acre, you would multiply the amount of acres and you should get the amount of sheep that farm holds.
A. 2 x 7 = 14 meaning there should be only 14 sheep at a farm that only has 2 acres of land.
B. 3 x 7 = 21 meaning there should be only 21 sheep at a farm that only has acres of land.
C. 6 x 7 = 42 meaning there should be only 42 sheep at a farm that only has 6 acres of land.
D. 2 x 7 = 14 meaning there should be only 14 sheep at a farm that only has 2 acres of land.
Hope this helps!

After school, Diana had a science club meeting for 1 hour and 20 minutes, followed by a choir rehearsal that lasted for 1 hour and 35 minutes. If Diana got out of school at 1:40 P.M., what time did the choir rehearsal end?
Answer:
3:15PM
Step-by-step explanation:
If If Diana got out of school at 1:40 P.M, this and spent 1 hour 35 minutes at the rehearsal, to know the time that the choir rehearsal ends, we will have to add the time spent at rehearsal to the time he got out of school;
1:40 P.M + (1hr 35 minutes)
1:40 P.M + 1 hr = 2:40PM
2:40PM + 35mintes = 2:40PM + (20mintes) +15 minutes
[2:40PM + (20mintes)] +15 minutes = 3:00pm + 15 minutes
3:00pm + 15 minutes = 3:15PM
Hence the choir rehearsal ends at 3:15PM
