Answer:
9 m²
Step-by-step explanation:
s = half the perimeter = (a+b+c)/2
the perimeter in our case is
a+b+c = 16
so, s = 16/2 = 8
and the sides are
7 m
6 m
16 - 7 - 6 = 3 m
therefore, we get
area = sqrt(8(8-7)(8-6)(8-3)) = sqrt(8×1×2×5) = sqrt(80) =
= 8.94427191... ≈ 9 m²
Answer:
At break even cost = revenue
Step-by-step explanation:
A company is said to be at break even if the cost of producing an item is equal to the revenue generated from the sell of that item, that means there is no loss or gain.
If the cost function C(x) = 200 + 10x and the revenue function R(x) = 60x - x², where x is the amount of items produced. At break even, R(x) = C(x)
60x - x² = 200 + 10x
x² - 60x + 10x + 200 = 0
x² - 50 x + 200 = 0
x = 46 or x = 4 is the break even point

Answer:
If we sketch the line of best fit, we can determine that the slope is positive. 3) ... Based on the trend, predict the number of hybrid cars sold if the price of gas is $4.00 a gallon. A) ... 2 10 5 16 6 15 20 12 28 30 28 35 37 32 45 39 56 52 60 65 ... B). C). D). Explanation: Scatterplot A correctly shows Natalie's data.
Step-by-step explanation:
Where is crosses the x axis is the x intercept
it is also when y=0
so set y to zero
2x-3y=12
2x-3(0)=12
2x-0=12
2x=12
divide by 2
x=6
t
the y intercept=6 or (6,0)
