Help!!!!!!!!!!!!!!!!!!!!!​

Mathematics
1 answer:
Rufina [12.5K]2 years ago
8 0

Answer:

6

Step-by-step explanation:

There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra.

So without all the insignificant 0's, the number would look like this:

13.0049

A ball is thrown from the top row of seats in a stadium. The function h(t) = - 16t^2 + 80t + 96 gives the height, in feet, of th
Rudik [331]

Answer:

2s or 3s

Step-by-step explanation:

Given the function that models the height of the object as;

h(t) = - 16t^2 + 80t + 96

The ball reaches the ground when h = 0

Substitute

0 = - 16t^2 + 80t + 96

Divide through by -16

0 = t²-5t-6

t²-5t-6 = 0

t²-2t-3t+6 = 0

t(t-2)-3(t-2) = 0

(tt-2)(t-3) = 0

t - 2 = 0 and t-3 = 0

t = 2 and 3s

Hence it will take the ball 2s or 3s to reach the ground

Three fourths of a gasoline storage tank is emptied by filling each of five trucks with the same amount of fuel what part of the
Reil [10]

Answer:

Each vehicle received \frac{3}{20} of the total capacity of the storage tank

Step-by-step explanation:

we know that

To find out what part of the total capacity of the storage tank that each vehicle received, divide three fourths by five

so

\frac{(3/4)}{5}=\frac{3}{20}

therefore

Each vehicle received \frac{3}{20} of the total capacity of the storage tank

Sam is observing the velocity of a car at different times after three hours the velocity of the car is 51 km/h after five hours
kupik [55]
So you have initial velocity, final velocity, and time. One easy equation for this (that will give you acceleration) is V=vo+at
When plugged in this would become
59km/h=51km/h+a(2 hrs)
To graph the equation, if graphing for velocity, Make the x axis time, using scaling as either every half hour or every hour. And obviously y axis velocity. Once you have that you can graph your initial velocity and final velocity. If your teacher doesn’t want a super exact graph, Then you can eyeball it and use a curve but you need to find out the acceleration in order to do that because the car is accelerating meaning that the graph line will not be linear, rather it will be exponential.
