in a circle with a radius of 6 m, an arc is intercepted by a central angle of 7π4 radians. What is the arc length? Use 3.14 for π . Enter your answer as a decimal in the box. m

Answers

Answer 1
1. You can solve this problem by applying the formula for calculate the arc length of a circle, which is shown below:
 
 s=θr
 
 s is the arc lenght of the arc.
 θ is the central angle (θ= 7π^4 radians).
 r is the radius of the arc (r=6 m).
  
 2. When you substitute these values into the formula for calculate the arc lenght, you obtain:
 
 s=θr
 s=(7π^4 radians)(6 m)
 s=(7(3.14)^4 radians)(6 m)
 s=4082.89 m
 
 What is the arc length?
 
 The answer is:4082.89 m
Answer 2

Answer:

The correct answer is 32.97 m.

A dairy mixes chocolate milk to sell in gallon containers. They mix 2,365 cups of skim milk with 108 cups of chocolate syrup. If each gallon container holds 16 cups of the chocolate milk, how many full containers will be filled?

Answers

So to solve this equation, you need to first figure out how many cups are going to be in all. You can do this by adding the cups of skin milk (2365) and the cups of chocolate syrup (108 cups), which leaves you with a total of 2473 cups. 
Now, since each gallon is 16 cups and you are determining the amount of gallons, you take the total number of cups (2473) and divide it by the 16 cups. this then gets you the answer of 154.5635. BUT... Since it wants to know how many FULL containers... the real answer is simply 154 GALLONS
(2365 cups + 108 cups) ÷ 16 = 2473 ÷ 16 
                                               = 154.56
the quantity will fill a 16 containers

passing through (1,9),slope=2

Answers

Passes through (1, 9) with a slope of 2.

Assuming that we want this in slope intercept form, which is y=mx+b (m=slope, b=y-intercept) then we need to find the y-intercept! :)

To find the y-intercept (or b!!) you simply need to plug everything into slope intercept form using our given points.

y = mx + b

Plug everything in.

9 = 2(1) + b

Simplify.

9 = 2 + b

Subtract 2 from both sides.

9 - 2 = b

b = 7

Therefore, our y-intercept is 7! :)

Now that we have both the y-intercept and the slope, we can finally plug this into a new equation, using slope intercept form.

y = mx + b

y = 2x + 7

~Hope I helped!~
y = ax + b

Here the slope is 2.

Then, y = 2x + b

The line is passing through (1;9).

We just have to substitute that in the equation.

9 = 2*1+ b
b = 9 - 2 
b = 7

That's the intercept.

Eventually, the equation is : y = 2x + 7

Hope this helps !

The quantity demanded x for a product is inversely proportional to the cube of the price p for p > 1. When the price is $10 per unit, the quantity demanded is 64 units. The initial cost is $150 and the cost per unit is $2. What price will yield a maximum profit?

Answers

q(p) = k/p^3 . . . . . . . . we want to find k
q(10) = k/10^3 = 64
k = 64,000

Revenue = q(p)*p = 64000/p^2
Cost = 150 +2q = 150 +2*64000/p^3

Profit = Revenue -Cost = 64000/p^2(1 -2/p) -150

Differentiating to find the maximum profit, we have
.. dProfit/dp = -2(64000/p^3) +6(64000/p^4) = 0
.. -1 +3/p = 0
.. p = 3

A price of $3 per unit will yield a maximum profit.

After taking core samples all over a cone-shaped mountain, you have determined that for every 1,000,000 yd3 there is about 2 lbs of gold to be mined. If the mountain has a base that is 2,000 yards wide and a height that is 3,000 yards tall, about how much gold is it expected to hold?

Answers

Final answer:

To find the expected amount of gold in the mountain, calculate the volume of the cone and multiply it by the gold density.

Explanation:

To determine the amount of gold expected to be held in the mountain:

Calculate the volume of the cone using the formula V = (1/3)πr²h.

Convert the volume to cubic yards since the gold density is given in lbs per 1,000,000 yd³.

Multiply the volume by the gold density to find the total amount of gold expected in lbs.

During a 5​-year ​period, 32% of snowstorms in a certain city caused power outage Fifty-one of the snowstorms did not cause power outages. Find the total number of snowstorms in this city over the 5​-year period.

Answers

To answer this question you will consider that if 32% of the storms did cause outages, then 100% (all of them)-32%= 68% did NOT produce a power outage. We can say that 68% of the total is 51.

This can be written as 0.68 x = 51 where x is the total number of snowstorms. Divide both sides by 0.68 to solve for x. X = 75 snowstorms. Another way to do this is to use Ratios. See the attached page for the strategy.
Answer:
Total number of snowstorms = 75 storms

Explanation:
We are given that:
32% of the snowstorms caused power outage
This means that we can get the percentages of the snowstorms that did not cause power outage as follows:
% of storms not causing outage = 100% - 32% = 68%

Now, we are given that the number of snowstorms that did not cause power outage is 51 
Assuming that the total number of storms is x, the equation would be as follows:
68% * x = 51
0.68x = 51
x = 51 / 0.68
x = 75 storms

Answers

Ok, we know that there are 270 degrees in a triangle, so just add 49+57, the you'll get 106, 270-106=164. ANSWER: 164
In a triangle everything must add up to 270 degrees meaning that if there is already 49 and 57 you must add them both together so 49+57 is 106 so you would now have to subtract 106 from the total number of the triangle, being 270.
So the equation would have to be 270-106= 164. The missing angle that you are missing is 164 degrees

Which relation is a function of x?

Answers

The correct awnset to that question would be D

Answer:

last option is correct.

Step-by-step explanation:

A relation is a function if each x value has a unique y value.

We'll use this concept to check whether the relation is a function or not.

For the first relation,

the x value 2 has two different values -9 and 8 . Hence, it is not a function.

For the second relation,

the x values -8 and 1 has different y values . Hence, it is not a function.

For the third relation

The x value -5 has different y values. Hence, it is not a function.

For the fourth relation

All the x values have unique y values. Hence, from the definition it is a function.

Therefore, last option is correct.

A deep-sea diver must descend and ascend in short steps to equalize pressure on his body. If the diver rises toward the surface too fast, he may suffer from a physical condition called "the bends." Suppose the diver started at 82 feet below the surface and rose in 5 steps of 15 feet each. Use an integer to describe his new position in relation to the water surface.

Answers

Start by multiplying 15 by 5, and you get 75. then subtract that from 82, and you get 7. Since you are below the surface, the number is negative. So you get -7. 

Answer:

-7 feet

Step-by-step explanation:

The total distance the diver rose is 5*15 = 75 feet

If we take the zero at the water surface, then the initial position, that is, 82 feet below the surface has to be considered as -82. The 75 feet risen by the diver is a positive quantity, then his new position, in relation to the water surface, is -82 + 75 = -7 feet, i. e. 7 feet below the surface.
