Answer:
Slope -1, y intercept +5.
Bold line, shaded above
Step-by-step explanation:
x + y - 5 ≥ 0
y ≥ -x + 5
For number 2. The answer is $6.49
<h2>D. If subjects knew they were receiving an active treatment, researchers would not have known if any improvement was due to the new medication or to the expectation of <u>feeling </u>better. If the researchers knew which subjects received which treatments, they might have treated one group of subjects differently from the other group.</h2><h2 />
For your question... the answer would be D
Answer:
A =62x^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is given by
A=2(wl+hl+hw)
Given a width of 2x and length of 3x and a height of 5x, substitute into the equation
A = 2(2x*3x+ 5x*3x+ 2x*5x)
A = 2(6x^2 + 15x^2 +10x^2)
Combine like terms
A = 2(31x^2)
A =62x^2
Answer:
27.5
Step-by-step explanation:
this is the trigonometric ratio.. we are looking for d... that is the opposite... any side facing the angel is the opposite.... so the longest side of the right angle triangle is the hypotenuse........ so you are looking for the opposite and you are giving the hypotenuse.... so the easiest way to know how to find it is by using this way...... SOH CAH TOA..... the first words stand for sin cosine and tangent of angles.... we are using sin.... because it says opposite / hypotenuse... and as you can see the angle which is 39 degree we will use sin 39.....what will be sin 39=d/30m....then ull cross multiply.... d=30m* sin 39.....
d = 30m *0.963
d = 28.8
but since 27.5 is dere....
you can round up to 1 sig. f =28
