Answer:
A) The parallelogram is a rhombus
Step-by-step explanation:
A rhombus is an equally 4-sided figure with two acute angles and two obtuse angles opposite of each other.
The <span><u>principle of exception</u> is the managerial principle that states that </span><span>control is enhanced by concentrating on the exceptions to, or significant deviations from, the expected result or standard.
This also refers to the fact that only what is important in a budget or a plan is shown to the manager, while the rest is excluded. </span>
It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).
So, use "arctan x" instead.
Then the problem becomes: "differentiate cos (arctan x)."
You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:
(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]
Answer:
16/81
Step-by-step explanation:
(2/3)^4 = (2/3)*(2/3)*(2/3)*(2/3)
= 16/81
We have to calculate the suface of the four walls and the ceiling.
Surface of the four walls=2(10 ft * 10ft ) + 2(12 ft * 10 ft)=200 ft² + 240 ft²=
=440 ft²
Surface of the ceiling=10 ft * 12 ft=120 ft²
Total surface=440 ft² + 120 ft²=560 ft²
Now, we have to caluclate the number of gallons of paint.
1 gallon------------------------400 ft²
x----------------------------------560 ft²
x=(1 gallon * 560 ft²) / 400 ft²=1.4 gallons.
answer: Ryan need to paint all four walls and the ceiling 1.4 gallons.
