Answer:
571,725 J
Step-by-step explanation:
KE = 1/2mv²
KE = 1/2(1050 kg)(33 m/s)² = 571,725 J
Answer:the volume formula is in the reference sheet.
Step-by-step explanation:
Step-by-step explanation:
5(x + 7) = 15
x+7=3
x=-4!!!!!!
you divide 29:11= 2 7/11
so you have 2 full vans and one with 7 students.
so yes the answer is 7
Answer:
y= -4x^2 + 15x - 14
Step-by-step explanation:
A parabola is always in the form y = ax^2 + bx + c.
Substitute each point to produce different equations:
-14 = 0a + 0b + c = c
so c = -14
-3 = a1^2 + b1 + c = a + b - 14
so a + b = 11
0 = a2^2 + b2 + c = 4a + 2b -14 = 0
so 4a + 2b = 14
if we double a + b = 11 we get 2a + 2b = 22
Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15
We don't need to use the (3,5) points as we have all the information we need.
