Answer:
2*10 ^0 = 2
Step-by-step explanation:
9 * 10^12 ÷ 4.5 × 10^12
Divide the numbers
9/4.5
=2
Divide the exponents by subtracting
10^12 ÷ 10^12 = 10 ^(12-12) = 10^0
Put them back together
2 * 10 ^0
2
Answer:
Step-by-step explanation:
Light is considered to be without mass, but it has energy. According to Einstein, energy can be
equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is
so small that it can be ignored and so we say that light travels in a straight line.
The above statement does not hold true when light passes near a star. A star possesses a very
high gravity field that bends light such that the change of direction is observed.
Answer:
8.55 inches tall
Step-by-step explanation:
equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.
Now plug in 4.6 for t you get:
h = -0.75t + 12
h = -0.75(4.6) + 12
h = -3.45 +12
h = 8.55 inches tall
Answer:
(-3,2)
Step-by-step explanation:
This equation is written in vertex from
y = -4(x + 3)2 + 2
Vertex from is
y = a(x - h)2 + k, where vertex is (h,k).
We can rewrite our equation
y = -4(x - (- 3))2 + 2.
So vertex is (-3,2)
