Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₁=8
leg₂=15
hypotenuse=s
hypotenuse²=(8)²+(15)²
hypotenuse²=64+225
hypotenuse²=289
hypotenuse=√289
hypotenuse=17
Answer: s=17
<span>a. find the number of units of tacos she must sell to minimise her cost.
</span>to find a minimum we need to find the function derivative and make it equal to zero:
dc/dx = 2x - 40 = 0
2x = 40
x = 20
therefore to minimize the cost, she needs to sell 20 units of tacos
<span>b. find the minimum cost.
</span>that can be done by substituting the previous result, 20 tacos, in the original equation:
<span>C(x) = x^2 - 40x + 610
</span>C(20) = (20)^2 - 40(20) + <span>610
</span>= 400 - 800 + 610
= 210
the minimum cost will be 210 dollars
Answer:
ok
Step-by-step explanation:
ok so the sum mustbe 36
and as this is a parallelogram that means opposite angle are the same and so one of the is 125that means that the opposite is 125 too, the sum is 250
360-250=110 and as one of the side must sum up to the half of 110 which is 55 and substract (55-22=33)
4=33
so is 5 =33
6=22
