Maria throws a softball straight up into the air with an initial velocity of 50 ft/sec. The ball leaves her hand when it is exac

Nataly_w [17]

Answer:

The equation that models the situation is $s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}$ .

Step-by-step explanation:

Let suppose that effects from air friction and Earth's rotation can be neglected, so that the softball can be modelled experiment a free fall, that is, an uniform accelerated motion due to gravity. From we know the initial velocity and position of the position and we can determine the final position of the ball as a function of the final velocity:

$v_{f}^{2} = v_{o}^{2}+2\cdot a \cdot (s_{f}-s_{o})$ (1)

Where:

$s_{o}$ , $s_{f}$ - Initial and final position of the softball, measured in feet.

$a$ - Acceleration, measured in meters per square second.

$v_{o}$ , $v_{f}$ - Initial and final velocities of the softball, measured in feet per second.

If we know that $v_{o} = 50\,\frac{ft}{s}$ , $a = -32.174\,\frac{m}{s^{2}}$ and $s_{o} = 4\,ft$ , then the equation that models the situation is:

$v_{f}^{2} = 2500-64.348\cdot (s_{f}-4)$

Then, we clear the final position of the softball:

$-\frac{v_{f}^{2}-2500}{-64.348} = s_{f}-4$

$s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}$

The equation that models the situation is $s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}$ .

Will mark Brainliest! Which of the following is not a condition for a tessellation? The shape or shapes must be repeated. The sh

uysha [10]

Answer:

Option 1 is correct.

Step-by-step explanation:

We have to select the option which is not the condition of a Tessellation.

A tessellation is a regular pattern made up of shapes that perfectly fit together or we can say it is an arrangement of shapes closely fitted together, especially of polygons in repeated pattern with no overlaps and no gaps.

A tessellation use repeated shapes to completely cover a plane with no overlaps or gaps.

Daily life examples of tessellation are honey combs, to man-made objects, like architecture and quilts.

A tessellation can use one or more geometric shapes. Hence, from the given options only the first option is not a condition for tessellation.

Answer:

perimeter=25.12 ft

Area=50.24 ft^2

Step-by-step explanation:

Radius=4 feet

π=3.14

Perimeter=2 x π x Radius

Perimeter=2 x 3.14 x 4

Perimeter=25.12 feet

Area=π x radius x radius

Area=3.14 x 4 x 4

Area=50.24 ft^2
