Nina [5.8K]

Answer:

Step-by-step explanation:

<u>430</u><u> </u> × <u>100</u> = <u>430</u> = 86%

500 1 5

you are going to cancel. 100 divided by 100 leaves 1. 500 divided by 100 is 5.

The velocity,v of a missile is related to time t, By the equation v=5t^2+3t+1.calculate the time at which the velocity is minimu
Cloud [144]

Answer:

  • time: t = -0.3
  • minimum: v = 0.55

Step-by-step explanation:

For quadratic ax^2 + bx + c, the extreme value is found at x=-b/(2a). For your quadratic, the minimum is found at ...

  t = -(3)/(2(5))

  t = -0.3 . . . . . time of minimum velocity

__

The value of velocity at that time is ...

  v = 5(-0.3)^2 +3(-0.3) +1 = 5(.09) -.9 +1

  v = 0.55 . . . . . value of minimum velocity

Can you guys pls help me eith this one plsss

The answer is 16 3/8.

So, to find out the total weight we have to add them all up. However, since we need a common denominator to add them up, we have to change the denominator of the first two mixed fractions, 2 1/2 and 1 1/2. Since we know that 2 is a factor of 8, we know that we can use 8 as the common denominator. The third mixed fraction already has a denominator of 8 so we just have to change the denominator of, 2 1/2 and 1 1/2. To do this, we just have to multiply the numerator and denominator by 4 to get, 2 4/8 and 1 4/8. Next, we can add them all up. We first add the fraction part, 4/8 + 4/8 + 3/8, which would give us 11/8, which can be turned into 1 3/8. Finally, we just have to add the whole numbers and 1 3/8, 2 + 1 + 12 + 1 3/8, to get 16 3/8.
