Answer:
A
Step-by-step explanation:
Given the solutions of a quadratic, say x = a, x = b then the factors are
(x - a) and (x - b) and the function is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the solutions are x = 5 and x = - 1, thus the factors are
(x - 5) and (x - (- 1)), that is (x - 5) and (x + 1), thus
f(x) = (x - 5)(x + 1) → A
I = PRT/100
P = Principal, R = Rate, T = Time
I = 1500 * 7.5 * 1.5 /100
I = 168.75
Interest owed = $168.75
Pretty sure the one of the left is higher than the one on the right
The slope is: -0.6
The Y-Intercept is: -3.4
So here is how we are going to prove that <span>(2(tan x - cot x) / (tan^2 x - cot^2 x} = sin (2x). Follow it step by step:
LS = </span><span><span>2(tanx−cotx)
</span><span> ------------------
ta<span>n^2</span>−co<span>t^2</span>x
= </span></span>2(tanx−cotx<span>)
----------------------
</span><span>(tanx−cotx)(tanx+cotx)
= 2
-------------------
</span><span>(tanx+cotx)
= 2
-----------------
S</span>i<span>n2</span>x+co<span>s2</span><span>x
----------------</span><span> sinxcosx
= 2

</span> sinxcos<span>x
</span> = 2sinxcosx
= sin2x
