Answer:
39
Step-by-step explanation:
sqrt(39*13*13)
= sqrt(1521)
= 39
The probability is 1/5, or 20%.
Explanation there are only 2 numbers on the die divisible by 4, those being 4 and 8, therefore 2/10 which simplifies to 1/5 or 20% I hope this helps :)
Answer:
0.0538% (3 sf)
Step-by-step explanation:
annual = 1 yr = 12 months = 52 weeks
2.8% / 52 = 0.053846153
To determine the marginal cost of the production, one needs to derive the given equation for the cost,
c(x) = 6x4 - 30x3 - 54x2 + x + 2
The derivative of the equation in terms of x is as reflected below.
c'(x) = 24x3 - 90x2 - 108x + 1
Equate the derivative to zero in order to determine the value of x .
c'(x) = 0 = 24x3 - 90x2 - 108 + 1
The value of x from the equation is 4.025.
Substituting x to the original equation,
c(x) = -1254.35 and at c(0) = 2
Answer:
1 and 3
Step-by-step explanation:
So they asked you to use the quadratic formula. The quadratic formula is x=-b+/-sqrt b^2-4ac/2a.
So your equation is x^2-4x+3.
x^2 is a. -4 is b. and 3 is c.
x=4+/-sqrt (-4)^2-4(1)(3)/2(1).
This will equal 4+/-sqrt16-12/2
It will simplify to 4+/-2/2.
No you have two equations 4+2/2 and 4-2/2.
4+2/2=3.
4-2/2=1.
Your answers are 1 and 3.
