Answer:
Circumference, C = 81.68 units
Step-by-step explanation:
Given that,
The radius of the circle, r = 13 units
We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :
C = 81.68 units
So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
In 16 months, two trees will be of same height
The trees will be of 58 inches tall
<em><u>Solution:</u></em>
Let "x" be the number of months
<em><u>The maple tree that is 42 inches tall is growing 1 inch per month</u></em>
Thus, equation for maple tree is given as:
Maple tree : 42 + 1 inch (number of months)
Maple tree : 42 + x ------- eqn 1
<em><u>The oak tree that is 10 inches tall is growing 3 inches per month</u></em>
Thus, equation for oak tree is given as:
Oak tree : 10 + 3 inch (number of months)
Oak tree : 10 + 3x -------- eqn 1
<em><u>For two two trees to be equal in height, equate eqn 1 and eqn 2</u></em>
Thus, in 16 months, two trees will be of same height
<em><u>What will that height be?</u></em>
Substitute x = 16 in any one eqn
Thus the trees will be of 58 inches tall
Answer: see attached graph
<u>Step-by-step explanation:</u>
Choose values for t and plug them into the x equation and y equation to find the x,y coordinates.
Usually there is an interval provided. Since you did not specify an interval, I chose to use [-2, 2].
