The answer is a) 12m^3 + 10n^2
Answer:
Step-by-step explanation:
The appropriate trig identity is ...
Here, you have a scale factor of 6 and a=3θ, b=θ. Filling in these values gives ...
The answer is 9
both 81 and 63 are dividable by 9, and nothing higher
Standard form is ax+by=c
first we use
y-y1=m(x-x1)
a point is (x1,y1)
the slope is m
the slope between the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(1,1) and (3,4)
slope=(4-1)/(3-1)=3/2
a oint is (1,1) and slope is 3/2
y-1=3/2(x-1)
y-1=3/2x-3/2
solve for ax+by=c form, a is normally positive and a and b and c are whole numbers
times 2 both sides
2y-2=3x-3
minus 2y
-2=3x-2y-3
add 3
1=3x-2y
3x-2y=2

<u><em>The correct question is</em></u>
A helicopter flying at an altitude of 600 ft dropped a package to a lifeboat. Use the formula t= √h/4 to find how many seconds it takes for the package to reach the lifeboat. Round your answer to the nearest tenth of a second
we have
substitute the value of h in the formula
