Answer:
Mile Run = 12.85 Long Jump = 6.63 Softball Toss = 22.1
Step-by-step explanation:
To do this you do not just plug it in. If you read it carefully, you would have to add. For example, Brianne would run 2.36 minutes faster than Crystal, so that would be 10.49 + 2.36 = 12.85. There you go! Hope this helps!
Translation of a line segment doesn't affect it's length, 'cause it has shifted from one location to another, no change in it's size.
In short, Your Answer would be Option B
Hope this helps!
First you would simplify what's in the square root, to get root 20. If you want the exact number, and not the approximation, you would take out whatever squares are in that number (20=2*2*5) so your answer is 2root5.
However, if you want the approximation, simply plug it into your calculator and get 4.18154055.
Answer:
136.34 m to the nearest hundredth.
Step-by-step explanation:
The runners paths and the distance between them after 30 second form a triangle.
The side opposite the 85 degree angle is 180 m and one of the other sides is 130 m.
We need to find the third side.
We can use the Cosine Rule to do this:
If the third side is x m then:
180^2 = 130^2 + x^2 - 2*130x cos 85
180^2 = 130^2 + x^2 - 260 * x * 0.08716
180^2 = 130^2 + x^2 - 22.6616 x
x^2 - 22.6616 x - 15500 = 0
x = [22.6616 +/- sqrt ((-22.6616)^2 - 4 * -15500) ] / 2
x= 136.34 m.
Answer:
Step-by-step explanation:
hello :
h(t) = -t²+8t
the highest point is the vertex of this prabola (-b/2a ; h(t) )
a= -1 and b= 8 -b/2a = - (8)/2(-1) = 4
h(4) = -(4)²+8(4) = -16+32 = 16
first answer : 16
second answer : 4
