Answer:
Step-by-step explanation:
express b^-4 with a positive exponent using:
Answer:
(5,-3)
Step-by-step explanation:
Rewrite the equation in vertex form
y =-(x-5)^2 - 3
You take the value of -5 (that would be your x value) and change it to the opposite sign -> +5
Then you take -3 (that would be your y value) and take it as it is
therefore the answer is (5, -3)
<span>We are given f(1) = 0 and f(2) = 1.
Going forward, the term is the sum of the two previous terms.
f(3) = f(2) + f(1) = 0 + 1 = 1.
f(4) = f(3) + f(2) = 1 + 1 = 2
f(5) = f(4) + f(3) = 2 + 1 = 3
This matches answer B.</span>
Given:
In ΔWXY, x = 680 inches, w = 900 inches and ∠W=157°.
To find:
The all possible values of ∠X, to the nearest degree.
Solution:
Law of Sines:
For ΔWXY,
Now,
Therefore, the value of ∠X is 17 degrees.
Answer:
(a) 20256.15625
(b) 17642.78546
Step-by-step explanation:
(a) There's a formula for this problem y = A(d)^t where, A is the initial value you are given, d is the growth or decay rate and t is the time period. So, in this case, as the car cost is decreasing it is a decay problem and we can write the formula as such; y = A(1-R)^t
So, in 5 years the car will be worth, 25500(1-4.5%)^5 or 20256.15625 dollars
(b) And after 8 years the car will be worth 25500(1-4.5%)^8 or 17642.78546 dollars.
