Which of the statements below provides evidence that sine and cosine are cofunctions? sin(30°)=cos(30°) sin(60°)=-cos(60°) sin(30°)=cos(-30°) sin(30°)=cos(60°)

The sine of an angle equals the cosine of its complement.

D. sin(30°) = cos(60°)

Option D. is the answer.

Step-by-step explanation:

In this question we have to find the statement that provides incidence that sine and cosine are co-functions.

As we know co function identities clearly say

(

A. For x = 30° or

Or

B. For x = 60°

sin(90-60) = cos(60)

sin(30) = cos(60)

Which is similar to option D.

Therefore, Option D. is the the correct answer.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
