Step-by-step explanation:
volume of sphere = 288
based on formula, V = 4/3πr³
288 = 4/3(3.14)r³
288 = 4.187(r³)
r³ = 288/4.187
r =
r = 4.09
= 4.1
Answer:
We have four functions:
For f(x) we have two points (-2,2) and (-1,-1)
we will use two point form which is:
So, on substituting the values we get:
So, f(x)=-3x-4
We have g(x)=3x-4
Now, we will from h(x) we have two points let initial point on monday is (0,4) and tuesday (1,1) again use two point form we get:
So, h(x)= -3x+4
Now, we will form j(x) we have three points (2,10) , (-2,6) and (2,22)
We will use (-2,6) and (2,22) to find the function with two point form.
j(x)= 4x+14
To find the slope we will compare the given function with general equation which is y= mx +c; m is the slope
And to find y-intercept we will put x=0
f(x)=-3x-4
Slope is: -3
And y-intercept is: (0,-4)
g(x)=3x-4
Slope is: 3
And y-intercept is: (0,-4)
h(x)= -3x+4
Slope is: -3
And y-intercept is: (0,4)
j(x)= 4x+14
Slope is: 4
And y-intercept is: (0,14)
Question:
A camel can drink 25 gallons of water in 10 minutes. How many cups of water can the camel drink in 10 minutes?
Solution:
A)
1 cup = 0.25 quarts.
4 quarts= 1 gallon
Then, according to this information, we get the following table:
B)
Note that 4 quarts= 1 gallon, then 1 gallon is equivalent to 16 cups.
C)
Then, 25 gallons are equivalent to:
D. According to the above information, we obtain that 25 gallons of water are 400 cups .
So that, we can conclude that the correct answer is:
The camel can drink 400 cups of water in 10 minutes
