20 tomato and 10 rose because 20 x 1 is 20 and 10 x 2 is 20
Answer:
14.4841
Step-by-step explanation:
Let "a" and "b" be some number where:
a - b = 24
We want to find where a^2 + b^2 is a minimum. Instead of just logically figuring out that the answer is where a=b=12, I'll just use derivatives.
So we can first substitute for "a" where a = b+24
So we have (b+24)^2 + b^2 = b^2 +48b +576 + b^2
And that equals 2b^2 +48b +576
Then we take the derivative and set it equal to zero:
4b +48 = 0
4(b+12) = 0
b + 12 = 0
b = -12
Thus "a" must equal 12.
So:
a = 12
b = -12
And the sum of those two numbers squared is (12)^2 + (-12)^2 = 144 + 144 = 288.
The smallest sum is 288.
9 and 250 thousandths written as a mixed number is as much as 9 250/1000. We can simplify it, so we'll get:
9 25/100
Or even:
<u>9 1/4

I hope it will help you :)
Answer:
v = 1
Step-by-step explanation:
v -10= -9
Add 10 to each side
v -10+10= -9+10
v = 1
