Find the slope of a line that is perpendicular to the line containing the points [-2,-1] and [2,-3]. How did you find it?

1 answer:

8 0

A line perpendicular to another will have the opposite sign and be flipped

ex: slope is 4/5 the other lines slope will be -5/4

(-2,-1) (2,-3)

slope formula

y2-y1/x2-x1

-3-(-1)
____
2-(-2)

-3+1
___
2+2

-2
___
0

the slope of the perpendicular line is 0/-2 which is just 0

A quantity with an initial value of 9100 grows continuously at a rate of 0.85% per hour. What is the value of the quantity after

ycow [4]

Answer:

$10,962,54$

Step-by-step explanation:

we know that

The equation of a exponential growth is equal to

$y=a(1+r)^x$

where

a is the initial value

r is the rate of growth

x is the time in hours

y is the value of the quantity

we have

$a=9,100\\r=0.85\%=0.85/100=0.0085$

substitute

$y=9,100(1+0.0085)^x$

$y=9,100(1..0085)^x$

For x=22 hours

substitute

$y=9,100(1..0085)^{22} =10,962,54$

Answer:

See below.

Step-by-step explanation:

We know that

tanA + tan B

tan (A + B) = ---------------------

1 - tanAtanB

Substituting for A + B

tan (A + B) = tan pi/4 = 1.

tanA + tan B

So ------------------ = 1

1 - tanAtanB

Therefore tanA + tan B = 1 - tanAtanB.
