Given, Earth's diameter is approximately 12,760,000 meters.
This number in scientific notation will be 1.276 × 10⁷
X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.
So your answer is
x=72
Acute Triangle
Answer:
The correct option D.
Step-by-step explanation:
The given function is
Where f(d) is the height of the ball at horizontal distance d.
Put f(d)=0, to find the distance where the ball touch the ground.
Quadratic formula:
Using the quadratic formula we get
Therefore the ball is in air between d=-0.146 to d=9.146.
The distance can not be negative, therefore the ball remains in the air between d=0 to d=9.146.
Therefore the correct option is D.
answer:
7.81
Step-by-step explanation:
ohh i like these questions this is the pythagorean theorem
1) a2+b2=c2
2) 5(2)+6(2)=c2
3) 25+36=c2
4) 61=c2
5) sqr root it
6) 7.81
Here are the senteces:
If those two were both the legs they would give us the answer of 7.81
gives us only two options of answers and the other choice is putting
one of those options as a hypotenuse.So our chance for the third side
being 7.81 is 50% chance.
have a good day
