Answer:
is the same as
by co-function identities
Step-by-step explanation:
Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
- sin (90° – x) = cos x
- cos (90° – x) = sin x
This means that .
Multiply the square root of 3 by the square root of 2 and itself.
The 3 cancels itself out and then you get A
Answer:
3
Step-by-step explanation:
The measure of the slope is at x = a
Differentiate using the power rule
(a
) = na
Given
y = x³ - 1, then
= 3x²
The slope at (1, 0) is
= 3(1)² = 3
