Answer:
a.
Step-by-step explanation:
A catenary looks a lot like a parabola. Only graph "a" has that appearance.
___
A graphing calculator can help you choose, or you can recognize the nature of the terms of the sum.
e^x looks like graph D; e^-x looks like graph B. Their sum will always be positive, so cannot create graph C. At x=0, the average of the two graphs B and D will be 1, corresponding to the minimum of graph A.
Answer:
13
Step-by-step explanation:
To find the determinant you subtract the the leading diagonal from the non-leading diagonal.
(4x-2)-(-7x3)
-8 - -21
NB A negative beside a negative gives you a positive number.
-8+21
=13
Answer:
30 basketballs
Step-by-step explanation:
one layer would be 3 x 2 = 6
- to find how much you would need to cover the bottom of the locker, you would use the numbers 3 and 2, then multiply them and you get 6. You would need 6 basketballs to cover the bottom of the locker. That would be your first layer
5 layers would be 6 x 5 = 30
- So the bottom would be filled with 6 basketballs. Now since the locker is 5 feet high multiply 6 x 5 and that would get you your total of basketballs
ANSWER
EXPLANATION
The given expression is
The greatest common factor is 2.
We factor 2 to obtain:
The expression in the parenthesis is prime.
This means that the quadratic expression in the parenthesis cannot be factored.
Hence the completely factored form is:
Answer:
412.15 ft to the nearest hundredth
Step-by-step explanation:
You have to use the tangent function since you are given one leg of a right triangle and you are looking for the other leg
Let x = the distance from boat to lighthouse
So, tan 27 = 210/x
x tan 27 = 210
x = 210/tan 27
x = 412.14820 = 412.15 ft to the nearest hundredth
