Whats is the slope of the line that passes through the points (3,-1) and (-2,-5)
Alchen [17]
You just subtract the x's and subtract the y's. So it will be 3- -2 and -1 - -5. Subtracting a negative is like adding a positive so your answer will be 5/4.

Find d^2y/dtheta^2 if y=sin^5
castortr0y [4]

Answer:

20 sin³O. cos²O - 5sin⁵O

Step-by-step explanation:

y = sin⁵O

Using the Chain Rule

dy/dO = 5 sin⁴O cosO

Using the Product / Chain rules:

d²y/dO² = 20 sin³O.cosO . cos O+ 5 sin⁴O * - sin O

= 20 sin³O. cos²O - 5sin⁵O

If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d
nika2105 [10]

Answer:

D = 25

Step-by-step explanation:

For 2 lines to be parallel, they must have the same sloe;

Given the coordinates (-2,4)and (5,D)

Slope = D-4/5-(-2)

Slope = D-4/5+2

Slope = D-4/7

Given the equation y = 3x + 4, comparing to y = mx+b

mx = 3x

m = 3

Hence the slope is 3

Equating the slopes

D-4/7 = 3

D-4 = 3*7

D-4 = 21

D = 21+4

D = 25

Hence the value of D is 25

andrezito [222]

Answer:

The answer to 9 is below

Step-by-step explanation:

2(L + W) = P

2(W + 5a - b) = 16a + 2b

2(W + 5a - b) = 2(8a + b)

W + 5a - b = 8a + b

W = 3a + 2b
