The answer is The function is constant from x = -2 to x = 1.
4/3(6/1) should give you 12
Answer:
May, April?
Step-by-step explanation:
I dont know lol
14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10
Answer:
A. -3√7/7
Step-by-step explanation:
We have the equation in trigonometry as following:
with (cos x)^2 different from 0, we have:
=>
As (cos θ) = √7/4 ≠ 0, so that we can replace θ into the above equation, we could have:
(tan θ)^2 = 1/[(cos θ)^2] -1
=> (tan θ)^2 =
=>(tan θ)^2 = 16/7 - 7/7 = 9/7
<em>=> tan θ = (3√7)/7 </em>
<em>or tan θ = - (3√7)/7 </em>
<em />
As θ is in quadrant IV, so that its tangent has negative value
=> tan θ = -3√7/7
So that the correct answer is A
