Fred bought a paperweight in the shape of a cone, as shown in the diagram.

25

Step-by-step explanation: First find the length of OC by dividing BC by 2. 30/2=15. Then use the Pythagorean Theorem (OC^2+AO^2=AC^2). 15^2=225. 20^2=400. 225+400=625. The square root of 625 is 25.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
