Answer:which z sqore are u talking about
Step-by-step explanation:
Answer:
The answer is 70.8
Step-by-step explanation:
You do 7x3 times 2 and then 3x2.6 and then 7x3 again. You add them all up and get 70.8
21 + 21 + 3.9 + 3.9 + 21 = 70.8
Answer:
D
Step-by-step explanation:
points (-4,4) and (0,5)
slope: (y2-y1)/(x2-x1)
(5-4)/(0+4) = 1/4
y intercept given: (0,5)
To answer this question, we must know some identities:
1. cos(x) is an even function, so cos(x)=cos(-x) [this makes choice (c) true]
2. sin(x) and cos(x) are the same periodic functions with a phase-shift of pi/2, so that sin(x+pi/2)=cos(x) [this makes choice (b) true]
3. also, sin(x) is symmetrical about pi/2, and cos(x) is symmetrical about x=0. This means that sin(x)=cos(pi/2-x) [ this case is not present in the choices ]
Answer:
see explanation
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ), thus
P(1, - 1 ) → P'(1, 1 )
Q(3, - 2 ) → Q'(2, 3 )
R(3, - 4 ) → R'(4, 3 )
