Answer:
8.9
Step-by-step explanation:
hypotenuse (h) = 21
perpendicular (p) = 19
base (b) = x = ?
We know by using Pythagoras theorem
b = √h² - p²
x = √ 21² - 19²
x = √ 80
x = 8.9
Hope it will help :)
Well when u divide 246÷3=82 but since i have to use rectangular models.........
X intercepts: (9,0)
y intercepts: (0,-6)
Answer:
311 students prefer sushi
Step-by-step explanation:
Let
x------> the number of students who prefer pizza
y -----> the number of students who prefer sushi
we know that
-----> equation A
-----> equation B
Substitute the equation B in equation A and solve for y

The number of machines that must be made to minimize the unit cost will be 230.
<h3>How to calculate the units?</h3>
From the information, the cost function is given as C(x)=0.9x²-414x+52,794. This will be differentiated.
C(x)=0.9x²-414x+52,794
C'(x) = d/dx(0.9x² - 414x + 52,794)
= 1.8x - 414
1.8x - 414 = 0
1.8x = 414
x = 414/1.8
x = 230
