Answer:
x = 5
Step-by-step explanation:
x is the length of the hypotenuse of this triangle. The length of one of the legs of the triangle is 3" and that of the other leg is 4".
Applying the Pythagorean Theorem: x^2 = 3^2 + 4^2, or 25
Thus, the length x is +√25, or 5.
x = 5

Answer:
x = 22
3x + 2 = 68°
Step-by-step explanation:
x + 3x + 2 = 90° because this is a right triangle
3x + 2 = 90
4x = 88 divide by 4
x = 22
3x + 2 replace x with the value we found
3×22 + 2 = 68°
Water is flowing into and out of a small reservoir. The total amount of water can be modeled by R, where R(t)=20-15sint^2/25 cubic feet, t is measured in hours and 0
Answers
9514 1404 393
Answer:
a) about -1.03 cubic feet per hour
b) R'(t) = -6/5t·cos(t^2/25); the rate of flow into the reservoir
c) 0.859 and 5.972 hours
d) 9.838 hours
Step-by-step explanation:
The rest of the problem statement is in the first attachment. See the second attachment for the graphing calculator input/output.
a) The average rate of change on the interval [0, 8] is ...
(R(8) -R(0))/(8 -0) ≈ -1.03004 . . . cubic feet per hour
__
b) The derivative can be found using the chain rule.
R'(t) = -15(2t/25)cos(t^2/25)
R'(t) = -6/5t·cos(t^2/25)
The derivative of the volume is the rate of change of volume, that is, the flow rate into the reservoir.
__
c) To find the time values when R' = 'average rate of change', we defined the constant a1 to be that average rate of change. The graphing calculator shows the curve R'(t)-a1, which has zeros at the times of interest. The times for which the instantaneous rate of change equals the average rate of change are t = 0.859 and t = 5.972 hours.
__
d) The time of interest is beyond the domain of the function. We cannot use the given function to determine the time of interest.
However, if we extend the domain to include the time of interest, we find it is t = 9.838 hours.

The weight of an object on the moon varies directly as its weight on earth. A person who weights 27.4 lb on the moon weights 164.4 lbs on earth. How many pounds would be a 270 lb person weigh on the moon?
Answers
Answer:
45 lb
Step-by-step explanation:
You can simple use unitary methods.
It is a simple visualization:
27.4 on moon = 164.4 on earth
(27.4/164.4) on moon = 1 on earth
270(27.4/164.4) on moon = 270 on earth
45 on moon = 270 on earth
Or, use, unitary method,
=> 164.4/27.4 = 270/x
=> x = (270 × 27.4)/164.4
=> x = 45
Or, use the concept "weight becomes 1/6 of the real one(of that on earth)".
270 lb on moon = 270/6 = 45 lb
Alyssa is helping to set up drinks and snacks for a luncheon.
Alyssa has 4.5 liters of lemonade to pour into pitchers. Each pitcher holds 0.9 liter of lemonade. If Alyssa pours an equal amount of lemonade into each pitcher, how many pitchers does she fill?
Alyssa drew the model below to show how many pitchers she fills.
The grids represent the amount of lemonade that Alyssa has. The lines represent Alyssa's division.
Answer in at least 2 complete sentences.
Is Alyssa's model correct?
Explain how do you know?
Answers
Answer:
Haha this isn't college Alyssa fills 5 pitchers. 4.5 divided by the liters of lemonade(0.9) equals 5 pitchers because 9x5=45 so, 4.5 liters of lemonade divided by 0.9 liters equals 5 pitchers.
