angle 1 and angle 2 are complementary angles. given the following information, find measures of both angles

kifflom [539]

∠1 and ∠2 are complementary.
∠1 + ∠2 = 90°

Question a:

∠1 = 23°
∠2 = 90 - 23 = 67°

Ans: 67°

Question b:
∠1 = x
∠2 = 2x + 3
x + 2x + 3 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29

∠1 = 29°
∠2 = 2(29) + 3 = 61°

Ans: ∠1 = 29°, ∠2 = 61°

Find the value(s) of x where the tangent to the graph of y=e^5x is parallel to the

Alik [6]

Answer:

There are none.

Step-by-step explanation:

No calculus involved:

The line, in slope-intercept form, has equation $y=-10x+17$ , ie is always decreasing (easy to spot applying the definition)

Meanwhile, $y=e^{5x}$ is always increasing over its domain.

At no point the tangent will be decreasing.

Let's use calculus

We are to solve the equation $y'(x) = -10 \rightarrow 5e^{5x} = -10 \rightarrow e^{5x}=-2$ which has no real solutions.
