(8/16) would be the slope
Answer:
7
Step-by-step explanation:
2v ÷ e + 3
we want to find the value of the expression when v = 10 and e = 5
to do so we substitute the values into the expression
2v ÷ e + 3
==> substitute 10 for v and 5 for e
2(10) ÷ 5 + 3
We now evaluate using bpemdas
==> multiply 2 and 10
20 ÷ 5 + 3
==> divide 20 by 5
4 + 3
==> add 4 and 3
= 7
Answer:
3/13
Step-by-step explanation:
8/13 subtract by 5/13. If the denominator is the same, you keep it, don't change it. Just subtract the numerator.
Make sure to simplify, if it is already simplified that will be the answer.
Answer:
The expression of h as function of x is h = ![\sqrt{(d + 5500) (d - 5500)}](https://tex.z-dn.net/?f=%5Csqrt%7B%28d%20%2B%205500%29%20%28d%20-%205500%29%7D)
Step-by-step explanation:
Given as :
The distance of blimp (AB) = 5500 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be Ф
So , cos Ф =
= ![\frac{h}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7Bd%7D)
And sin Ф =
= ![\frac{5500}{d}](https://tex.z-dn.net/?f=%5Cfrac%7B5500%7D%7Bd%7D)
∵, cos²Ф = 1 - sin²Ф
So,
= ![1 - (\frac{5500}{d})^{2}](https://tex.z-dn.net/?f=1%20-%20%28%5Cfrac%7B5500%7D%7Bd%7D%29%5E%7B2%7D)
Or,
=
Or, h² = d² - 5500²
∴ h = ![\sqrt{d^{2}- 5500^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7Bd%5E%7B2%7D-%205500%5E%7B2%7D%7D)
Or, h = ![\sqrt{(d + 5500) (d - 5500)}](https://tex.z-dn.net/?f=%5Csqrt%7B%28d%20%2B%205500%29%20%28d%20-%205500%29%7D)
Hence The expression of h as function of x is h =
Answer
Answer:
a) $4000
b) $2000
Step-by-step explanation:
a)
interest = Principal x rate as decimal x time
interest = 20,000 x 0.05 x 4
interest = 4000
b)
interest = Principal x rate as decimal x time
interest = 20,000 x 0.05 x 2
interest = 2000
you save $2000 if you pay after 2 years
