Answer:
-5 (4x+y)
Step-by-step explanation:
Factor out -5, and -20/-5=4, -5/-5=1.
Since the end of the slide is 1 foot above the ground, the vertical rise of the
<span>slide is 8 - 1 = 7 feet, and since the slide rises at a 45 degree angle it will </span>
<span>have a horizontal run of 7 feet as well. Thus by Pythagoras the length of the </span>
<span>slide is sqrt(7^2 + 7^2) = sqrt(98) = 9.90 feet, which is about 10 feet.</span>
Area = 1/2 x base x height
Base = area x 2 / height
Base = 6 1/4 x 2 = 12 1/2 / 3 1/3
Base = 3 3/4 m
Answer,
<u><em>-7</em></u>
Explanation,
<u><em>Hello! All we are doing here is simply subtraction :-)</em></u>
<em>-9 - 6 = -15</em>
<em>-15 - (-8) = -7</em>
<u><em>Hope This Helps :-)</em></u>
We know expression is used for represent the derivative.
Actually, derivative is the second name of " Rate of Change".
And if we read , it represents the "Rate of change of y with respect to x".
In simple words, a derivative is the rate of change or slope of a very small portion of a function.
dy represents very small change in y-coordinate and dx represents very small change in x-coordinate.
Because deriviate is the second name of " a very small rate of change".
We use to represent the derivative.
