Answer:
1
Step-by-step explanation:
Tangent of [5 pi]/4
The expression above is given in radian; when ever you have something like this- take note, it's in radian.
Pi [in radian] = 180 in degrees
Hence [5 pi]/4 = [5 x 180]/ 4 =5 x 45 = 225
So Tan 225 = Tan [225-180] =Tan 45
and Tan 45 =1
Answer:
B' (-4, -4)
Step-by-step explanation:
When you dilate from the origin, you multiply the coordinate points by the scale factor.
B (-1, -1) × 4 = B' (-4, -4)
I hope this helps :))
F(3)=-18
You just replace x for three for your equation and then use Ofer of operations to solve it.
So f(3)= 21+ 2(3)-5(3)^2
The exponent goes first: f(3)= 21+ 2(3)-5(9)
Next is multiplication: f(3)= 21+ 6-45
Now add: f(3)= 27-45
Finally subtract: f(3)= -18
Hope this helps!
Answer:
30 = 5y - 4x or 6 + (4x/5) = y (in mx + c = y form)
Step-by-step explanation:
slope =
- 
/ 
- 
now, = 2
= -5
insert the values of these two in the slope formula and equate it with 4/5.
by cross multiplication, obtain equation.
the equation is 30 = 5y-4x.
hope this helps you!
