Answer:
C
Step-by-step explanation:
Plug in -3 for x: y = -(-3)²+3 = -9+3 = -6 (-3,-6)
plug in 0 for x: y = =(0)² + 3 = 3 (0,3)
plug in 3 for x: y = -(3)² + 3 = -9+3 = -3 (3, -6)
Answer :y=−1
Step-by-step explanation:
y2+2y+1=0
Step 1: Factor left side of equation.
(y+1)(y+1)=0
Step 2: Set factors equal to 0.
y+1=0 or y+1=0
y=−1
Answer:
Step-by-step explanation:
We can do this quite simply by using Newton's equation: forcegravity = G × M × mseparation2 .
Suppose: your mass, m, is 60 kilogram; the mass of your colleague, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 -11 newton square metre kilogram-2.
Answer:
5sqrt(5) = q
-5sqrt(5) = q
Step-by-step explanation:
f(q) = q^2 -125
To find the roots set the equation equal to zero
0 = q^2 -125
Add 125 to each side
125 = q^2 -125+125
125 = q^2
Take the square root of each side
±sqrt(125) = sqrt(q^2)
±sqrt( 5*25) = q
±sqrt( 25)* sqrt(5) = q
±5* sqrt(5) = q
±5sqrt(5) = q
A) zero as the value of determinant is imaginary
