The figure RQTS is a clockwise rotation of figure DEFC, then:
The image of CD is
Answer: Option C. RS
600 every 10 years is the right answer
1 cg = 10^-5 kg
8.25 * 10^2 cg = 8.25 * 10^-3 kg
10^-12 kg = 1 nanogram
8.25 * 10^-3 kg = 8.25 * 10^9 nanograms
Therefore, 8.25 * 10^2 cg = 8.25 * 10^9 nanograms.
Answer:
$9,360
Explanation:
- $9 per hour, rewrite: 1 hour he earned $9
so for 1040 hours, he earned:
$9 * 1,040
$9,360
Step-by-step explanation:
Given the height of the rocket y in feet related to time after launch x related by the equation:
Y=-16x^2+189x+79
The rocket will hit the ground when y = 0
The equation will become:
0=-16x^2+189x+79
Rearrange
-16x^2+189x+79 = 0
multiply though by minus
16x^2-189x-79 = 0
Factorize and solve for x:
x = 189±√189²-4(16)(-79)/2(16)
x = 189±√35721+5056/32
x = 189±√40777/32
x = 189±201.93/32
x = 189+201.93/32
x = 390.93/32
x = 12.22secs
hence the rocket will hit the ground after 12.22seconds (to the nearest hundredth of a sec)
