<u>Given:</u>
The radius of the circle XY is XY = 11.4 in
The length of ZY is 15.2 in
The length of XZ is 19.6 in
We need to determine whether YZ is a tangent to the circle X.
<u>Is YZ tangent to the circle X:</u>
We shall determine whether YZ is a tangent to the circle X by using the Pythagorean theorem.
Thus, we have;
Substituting the values, we have;

Simplifying, we get;


Since, both sides of the equation are not equal, thus, YZ is not a tangent to the circle X.

Answer:
V=33.51in^3
Step-by-step explanation:
5inch-1 in
=4inch
divide by 2 because the problem gives diameter, not radius. (radius is half of diameter)
The space inside is a sphere so it will be
V=4/3πr^3
V=4/3*pi*(2)^3
V=33.51 inch cubed
Answer:
Option D (r(t) = 3.50t +25
; r(8) = 53)
Step-by-step explanation:
The fixed cost to rent the kayak $25. This is the cost which remains fixed irrespective of the usage of the kayak. The variable cost of using the kayak is the cost which depends on the usage of the kayak. It is mentioned that the kayak is used for 4 hours and the company charges $3.5 for every half hour. The cost function is given by:
r(t) = 25 + 3.5t ; there r is the total cost of using the kayak and t is the number of half-hours the kayak is used.
4 hours means that there are 8 half-hours. Therefore, t=8. Put t=8 in r(t).
r(8) = 25 + 3.5*(8) = 25 + 28 = 53.
Therefore, Option D is the correct answer!!!
