Answer:
x = ±2sqrt(2)
Step-by-step explanation:
x^2 = 8
Take the square root of each side
sqrt(x^2) = ±sqrt(8)
x = ±sqrt(4*2)
We know that sqrt(ab) = sqrt(a)sqrt(b)
x = ±sqrt(4)sqrt(2)
x = ±2sqrt(2)
the question in English
Nutritionists recommend that a person should drink an average of 2.5 liters of water in a day, to be well hydrated. How many liters of water should a person drink in a month to comply with a good hydration (Consider a month equal to 30 days) Formulate an algebraic expression to determine the total liters of water that a person should drink a given number of days.
Let
x-------> the number of days
y------> the total liters of water
we know that
------> algebraic expression to determine the total liters of water that a person should drink a given number of days
For x=30 days (1 month)
substitute in the formula
therefore
<u>the answer is</u>
Answer:
(gof) (1) = 0
Step-by-step explanation:
f(x) = -4x + 7
g(x) = 2x - 6
(gof) (1)
First find f(1)
f(1) = -4(1) + 7
f(1) = -4+7=3
Then put 3 in for x in g(x)
g(f(1) = 2(f(1))-6
= 2 (3) -6
= 6 -6
= 0
I’ll do the first one for you
5 x 2 = 10
10pi = around 31.42
You are really just multiplying the diameter by pi, if you are only given the radius, double it first
