vazorg [7]2 years ago
6 0

Step-by-step explanation:

1) P = 47,100 + 2,550t

Given P = 95000

So,

95000 = 47100 + 2550t

Subtract 47100 from both sides,

95000 - 47100 = 2550t

47900 = 2550t

Divide by 2550,

t = 47900/2550 = 18.78 = 18.8 years

2) Given P = 43,100 + 3,150t

Both P must be equal.

47100+2550t = 43100+3150t

Subtract 43100 and 2550t from sides,

47100- 43100 = 3150t - 2550t

4000 = 600t

Divide by 600,

t = 4000/600 = 6.67 = 6.7 years

R  = (12.500 *8) =

R= 100.000

R  = (12.500 - 500) ( 8 + 1)=

R=12000*9=

R=108.000

Step-by-step explanation:

Revenue  =  Members  *  (Cost Per Member)

R  = (12.500 *8) =

R= 100.000

R  = (12.500 - 500) ( 8 + 1)=

R=12000*9=

The point Al-2, 3) is translated using T: (x,y) → (x+4, y+2).
almond37 [142]

Answer:

The distance between A and A' is:

distance=\sqrt{20}

Step-by-step explanation:

Notice that point A' after the given translation becomes: (-2+4, 3+2) = (2, 5),

So one can calculate the distance between A (-2, 3) and A' (2, 5) using the distance formula:

distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\distance=\sqrt{(2-(-2))^2+(5-3)^2} \\distance=\sqrt{(4))^2+(2)^2} \\distance=\sqrt{(16+4} \\distance=\sqrt{20}

Help me throughout this question please!!!!!!​
vagabundo [1.1K]

\cos(2A)=\cos^2 A-\sin^2A=(\cos A+ \sin A)(\cos A-\sin A)

substitute the second term in LHS to get

{ (\cos A - \sin A)^2 \over \cos(2A))}

expand the square, \frac{1-2\sin A \cos A}{\cos 2A}= \sec2A- \tan 2A

(\sin (2\theta)=2 \sin\theta\cos\theta)
