We have :
p ( x ) = x² - 1 and q ( x ) = 5 ( x - 1 )
( p - q ) ( x ) = ( x² - 1 ) - 5 ( x - 1 )
Answer:
C ) ( x² - 1 ) - 5 ( x - 1 )
To get circumference you must multiply the diameter by pi(the equivalent to 3.14. If you multiply 4.25 by 3.14 you would get 13.345. If you need to round up it would be 13.3 inches.
Answer:
y=-2x-14
Step-by-step explanation:
Ok so first off understand what they are saying. there is a movie on sale for $22.10 which is 15 percent of the original price. So now what you do is set up the problem.
22.10 is = 15% of the price
x = 100% of the price (original price)
<u> 15 </u> = <u>22.10
</u>100 x
<u>
</u>now just use cross multiplication.
15x = 22.10 · 100
solve for x.
<u>15x</u> = <u>2210</u>
<u /> 15 15
x = 147.33333333 since the 3's go on forever you can simply put it into a fraction
x = 147 <u>3
</u> 9
<u>
</u>whenever there is a repeating number you can put it into a fraction but putting the repeating number over a 9

y=cos(2x)
<span>dy/dx=-2sin(2x) </span>
<span>dy/dx at the point x=pi/4 is </span>
<span>dy/dx=-2sin(2*pi/4) </span>
<span>dy/dx=-2 sin(pi/2) </span>
<span>dy/dx=-2 </span>
<span>therefore the slope of the tangent is -2
</span>
using this slope find the equation of the line
<span>(y-y')=m(x-x') </span>
<span>(y-0)=-2(x-pi/4) </span>
<span>y=-2(x-pi/4)</span>
