Answer:
c = 
Step-by-step explanation:
Given
15 = - 3(2c + d) ( divide both sides by - 3 )
- 5 = 2c + d ( subtract d from both sides )
- 5 - d = 2c ( isolate c by dividing both sides by 2 )
= c
Answer:
A boxplot is a standardized way of displaying the distribution of data based on a five number summary minimum, first quartile, median, third quartile , and maximum. It can tell you about your outliers and what their values are. It can also tell you if your data is symmetrical, how tightly your data is grouped, and if and how your data is skewed.

Let time is t
since they both went in opposite directions then the distance between them is the sum of the distance between each of them and the origin point
49t + 56t =420 is the equation
to solve: 105t = 420 , t = 4 hours
Answer:

![\frac{dS}{dt}=320 square centimeter per secondStep-by-step explanation:We are given that volume of sphere [tex]V=\frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=%5Cfrac%7BdS%7D%7Bdt%7D%3D320%20square%20%20centimeter%20per%20second%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3EStep-by-step%20explanation%3A%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3EWe%20are%20given%20that%20volume%20of%20sphere%20%3C%2Fp%3E%3Cp%3E%5Btex%5DV%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
Volume of sphere is increasing at a constant rate
cubic centimeters per second
We have to find the rate of radius at which increasing
when r= 10 cm
Differentiating w.r.t time


cm per second
Now ,we are given that surface area of sphere

Differentiate w.r.t time then we get


cm per second
