sorry if i am wrong
Answer:
1 - 2sin²5A
Step-by-step explanation:
cos10A = cos2(5A) = cos²5A - sin²5A = 1 - sin²5A - sin²5A = 1 - 2sin²5A
y = 3x-2x∧2+5x∧3
When we replace x with value 3 we get
y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126
good luck!!!
Im sorry I don't know the answer to the question
Slope formula: y2-y1/x2-x1
Question 1:
= 14-(-15)/1-(-11)
= 29/12
= 2 5/12
Therefore, the slope is 2 5/12 or 29/12.
Question 2:
= 12-(-19)/-9-16
= 31/-25
= -31/25
= 1 6/25
Therefore, the slope is 1 6/25 or -31/25.
Question 3:
= -3-(-3)/8-(-18)
= 0/26
Therefore, the slope is 0.
Best of Luck!
