A ball is kicked from the ground with a velocity of 38.50 ft/sec at an angle of 35 degrees. How many feet will the ball travel h

anzhelika [568]

Answer:

Horizontal distance is 142.12 feet.

Step-by-step explanation:

We have,

Velocity of the ball is 38.50 ft/sec. The angle of projection of the ball is 35 degrees.

It is required to find the horizontal distance covered by it before it comes back to the ground on its first bounce. It means we need to find the horizontal range of the projectile. Range of a projectile is given by :

$R=\dfrac{u^2\sin2\theta}{g}\\\\R=\dfrac{(38.5)^2\times \sin2(35)}{9.8}\\\\R=142.12\ ft$

So, the horizontal distance covered by it before it comes back to the ground on its first bounce is 142.12 feet.

Emily spent $55 from her savings on a new dress. explain how to descibe the change Emily's savings balance in 2 different ways

Step2247 [10]

S= savings before she bought the dress s - $55 would be her new balance after she bought the dress.

We could also talk about her savings now (after her purchase). If we let n=now
n + $55 would be her balance before she bought the dress.

Step-by-step explanation:

It appears that given geometrical shape is a HEXA-DECAGON or a 16 sided polygon.

Measure of one interior angle of hexa-decagon can be given as:

$\frac{(n - 2) \times 180 \degree}{n} \\ \\ = \frac{(16 - 2) \times 180 \degree}{16} \\ \\ = \frac{14 \times 45 \degree}{4} \\ \\ = \frac{7 \times 45 \degree}{2} \\ \\ = \frac{315 \degree}{2} \\ \\ = 157.5\degree \\$

Which of the following correlation coefficients would represent the strongest correlation? -0.9 -0.16 0.04 .78

kolezko [41]

Answer:

0.4 would represent the strongest correlation.

Step-by-step explanation:

Generally, a value of r greater than 0.7 is considered a strong correlation. Anything between 0.5 and 0.7 is a moderate correlation, and anything less than 0.4 is considered a weak or no correlation
