Answer:

1 1/3

Step-by-step explanation:

Use the formula $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$ to find slope.

Plug in the numbers:

$m=\frac{4-(-4)}{3-(-3)}$

Solve for the numerator and the denominator:

$m=\frac{8}{6}$

Simplify:

4/3

Slope is 1 1/3 or 1.333

olga55 [171]

Answer: The answer is D

Step-by-step explanation: So, we have five parts on it equaling 1, 2, 3, 4 and 5. The top number is our chance, and the bottom number is how many there are in total, so our answer is D, 1/5.

Hope this helps :)

Lim ln(tan x) as tends to pi/2 from the left

ioda

Let $x=\arctan y$ . Then $\tan x=y$ , and so as $x\to\dfrac\pi2^-$ , you have $y\to+\infty$ . The limit is then equivalent to

$\displaystyle\lim_{x\to\frac\pi2^-}\ln(\tan x)=\lim_{y\to\infty}\ln y=\infty$

4. What is the measure of angle ABD in the figure below?* D 2x A B с

katovenus [111]

Answer:

Measure of exterior angle ABD = 136°

Step-by-step explanation:

Given:

measure of ∠A = (2x + 2)°

measure of ∠C = (x + 4)°

measure of ∠B = x°

Find:

Measure of exterior angle ABD

Computation:

Using angles sum property

∠A + ∠B + ∠C = 180°

So,

(2x + 2) + (x + 4) + x = 180

4x + 6 = 180

4x = 176

x = 44

So,

measure of ∠B = x°

measure of ∠B = 44°

Measure of exterior angle ABD = 180 - measure of ∠B

Measure of exterior angle ABD = 180 - 44

Measure of exterior angle ABD = 136°
