A rectangular bed of a truck is 1 9/10 meters long,1 1/2 meters wide, and 1/2 meter tall. What is the volume of the truck bed?

Sophie [7]

Answer:

The volume of the truck bed is $1\frac{17}{40}\ m^{3}$

Step-by-step explanation:

we know that

The volume is equal to

$V=LWH$

substitute the values , but first convert to an improper fractions

$L=1\frac{9}{10}\ m=\frac{10*1+9}{10}=\frac{19}{10}\ m$

$W=1\frac{1}{2}\ m=\frac{1*2+1}{2}=\frac{3}{2}\ m$

$H=\frac{1}{2}\ m$

Find the volume

$V=(\frac{19}{10})(\frac{3}{2})(\frac{1}{2})=\frac{57}{40}\ m^{3}$

Convert to mixed number

$\frac{57}{40}\ m^{3}=\frac{40}{40}+\frac{17}{40}=1\frac{17}{40}\ m^{3}$

What is the maximum height of the basketball when the player passes the ball to someone? Initially, the ball moves at a speed of

ZanzabumX [31]

Answer with explanation:

Since the motion of the ball is projectile motion we shall use the equations for projectile motion.

The maximum height achieved by the projectile is given by

$h_{max}=\frac{v_{o}^{2}sin^{2}(\theta )}{2g}$

Applying the values we get

$h_{max}=\frac{12^{2}\times sin^{2}(45)}{2\times 9.81}\\\\h_{max}=3.669m$

The range of the projectile is given by

$R=\frac{v_{o}^{2}sin(2\theta )}{2g}$

Applying values we get

$R=\frac{12^{2}\times sin(2\times 45 )}{2\times 9.81}\\\\R=7.339m$

thus the maximum horizontal distance reached by the ball equals 7.339 meters after which it bounces thus a person standing 8 meters away will not be able to catch it.

(The height of the players is not taken into account since no info is given about their height.)

What is the polynomial 3y^2+(y+7)^2-15 after it has be simplified

kogti [31]

Answer:

4y^(2)+14y+31

Step-by-step explanation:

First you need to do (y+7)(y+7)

y^2+7y+7y+49

y^2+14y+49

Add it all together

y^2+14y+49+3y^2-15

4y^(2)+14y+31
