Please help me asap. Got stuck with this question

Temka [501]

Answer:

Step-by-step explanation:

$a.\\\frac{d}{dx}(\frac{-1}{1+x^2} )=\frac{d}{dx} [-1(1+x^2)^{-1}]=-1(-1)(1+x^2)^{-2}(2x)=\frac{2x}{(1+x^2)^2 }\\$

put 1+x²=u

2x dx=du

when x=0,u=1

when x=2,u=1+2²=5

$\int\limits^5_1 {\frac{1}{u}} \, du= ln |u| ,1 \to 5=ln5-ln1=ln 5-0=ln 5$

Not only would I like the value of x, but also I wonder how I’d go about solving this problem?

notsponge [240]

Answer:

x = 58

Step-by-step explanation:

This question can be solved by using the exterior angle property, which states that the exterior angle of a triangle = the sum of the two opposite interior angles.

62 lies on a line, so the exterior angle is 180 - 62, or 118 degrees.

Using the EAP, we can conclude the following:

(x + 2) + (x) = 118

2x + 2 = 118

2x = 116

x = 58

Hope this helps

What is the x-intercept of the line with this equation −2r+1/2 y=18?

Anon25 [30]

To find the x int, we will sub in 0 for y and solve for x...um...r

- 2r + 1/2y = 18
-2r + 1/2(0) = 18
-2r = 18
r = -18/2
r = -9

so the x int is (-9,0)

Question 7 (1 point)

Arisa [49]

Answer:

h = 452.5 ft

Step-by-step explanation:

Angle of elevation from P to top of the pole = 65°

Horizontal distance between the pole and point P = 21 ft

By Applying tan rule in the given triangle ABP,

tan(∠APB) = $\frac{AB}{PB}$
