You just need to isolate the d. So divide both sides by seven. You should end up with d=8
Y = sec^2 x
use the product rule
dy/dx = sec x * sec x tan x + sec x tan x sec x
= 2 sec^2 tan x
Step-by-step explanation:
the volume of a box (or prism) is always
length × width × height
so, box A
13 × 12 × 16 = 2,496 in³
box B
18 × 25 × 16 = 7,200 in³
box C
12 × 14 × 22 = 3,696 in³
box D
20 × 22 × 17 = 7,480 in³
so, she can use B or D.
Answer:
(0,-3)
Step-by-step explanation:
( r, theta)
We know that x = r cos theta
x = -3 cos (pi/2)
x = -3 *0 = 0
We also know that y = r sin theta
y = -3 sin (pi/2)
y = -3*1 = -3
The rectangular coordinates are
(0,-3)
let's say is "x", so "x" is then 100% of the whole bill.
we know 15% is 22.05, what is "x"?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 22.05&15\\ x&100 \end{array}\implies \cfrac{22.05}{x}=\cfrac{15}{100}\implies 2205=15x \\\\\\ \cfrac{2205}{15}=x\implies 147=x](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2022.05%2615%5C%5C%20x%26100%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B22.05%7D%7Bx%7D%3D%5Ccfrac%7B15%7D%7B100%7D%5Cimplies%202205%3D15x%20%5C%5C%5C%5C%5C%5C%20%5Ccfrac%7B2205%7D%7B15%7D%3Dx%5Cimplies%20147%3Dx)
