Answer:
<h3>The answer is 32cm</h3>
Step-by-step explanation:
Circumference of a circle = 2πr
where
r is the radius
To find the radius of the mat substitute the value of the circumference into the above formula and solve for the radius
Circumference = 200cm
200 = 2πr
Divide both sides by 2π
r = 31.83098
We have the final answer as
<h3>radius = 32 cm to the nearest whole number</h3>
Hope this helps
Answer: x^6 or x to the power of 6
Step-by-step explanation:
Not really sure what the expressions are but I just simplified the expression.
Answer:
y = c/x where c is a constant
Step-by-step explanation:
For y to vary inversely with x we know it must be something like y = 1/x which is the direct inverse. However this could be multiplied by a constant and still vary inversely with x, so let us define c as a constant, then y = c / x varies inversely with x
Answer:
if thers 480 its 480
Step-by-step explanation:
Let the function be
. (this is the general form of a quadratic equation, whose graph is a parabola. a is different from 0)
The average rate of change from x=-1 to x=-2 is found by the formula:
.
We are given the points (-1, 5) and (-2, 7), so we have f(-1)=5 and f(-2)=7, thus
-f(-2)+f(-1)=-7+5=-2.
Answer: b: -2
