Answer:
I think it's c
Step-by-step explanation:
because a*1=1
All of the other statements are incorrect because for one a+0=0 Only 0 can = 0
A*0=1? A number times 0 is always going to be zero
A+1=1? Only 0 is the only number that a number plus 0 is the same number
Answer:
The angle of elevation for Brendan is 40°
Step-by-step explanation:
To find the angle of elevation of Brendan, we will follow the steps below;
we can use the sine formula to find the angle of elevation of Brendan since we were given two sides and one angle
Using the sine rule;
= ![\frac{sin E}{e}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%20E%7D%7Be%7D)
From the diagram above, angle A = 65° side a = 155 m side e=110 m
angle E is what we are to find
we can now proceed to insert the values into the formula
= ![\frac{sin E}{110}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%20E%7D%7B110%7D)
cross-multiply
155 sinE = 110 sin65°
Divide both-side of the equation by 155
sin E = 110 sin65° / 155
sin E =0.64319
Take the sin⁻¹ of both-side of the equation
sin⁻¹ sin E = sin⁻¹ (0.64319)
At the left-hand side of the equation sin⁻¹ will cancel-out sin leaving us with just E
E = sin⁻¹ (0.64319)
E= 40°
The angle of elevation for Brendan is 40°
Answer:
C
Step-by-step explanation:
g(x) = f(x - π/3), so g(x) is f(x) shifted to the right π/3 units.
Answer C.
