Answer:

1. $x=18, y=6√(10)$

2. x=108, y=180

Step-by-step explanation:

The height of the right triangle drawn to the hypotenuse is the geometric mean of two segments of the hypotenuse (two legs' projections)

1. Use this property, so

$CD^2=AD\cdot BD\n \n6^2=2\cdot x\n \n36=2x\n \nx=18$

Consider right triangle BCD. By the Pythagorean theorem,

$BC^2=BD^2+CD^2\n \ny^2=18^2+6^2\n \ny^2=324+36\n \ny^2=360\n \ny=√(360)=6√(10)$

2. Consider right triangleGM*. By the Pythagorean theorem,

$G*^2=GM^2+M*^2\n \n240^2=GM^2+192^2\n \nGM^2=240^2-192^2=(240-192)(240+192)=48\cdot 432=144^2\n \nGM=144$

Use this property to find x:

$GM^2=192\cdot x\n \n144^2=192\cdot x\n \nx=(144^2)/(192)=108$

Consider right triangle GMCup. By the Pythagorean theorem,

$y^2=x^2+GM^2\n \ny^2=108^2+144^2\n \ny^2=32,400\n \ny=180$

Martina hits a volleyball ball upward with an initial velocity of 13 meters/sec. When she hits the ball, it is one meter above the ground. How long will it take the ball to hit the ground?

Answers

the ball will take 6.5 seconds to hit the ground

Final answer:

The question from the student is about time airborne for a volleyball hit upwards with an initial velocity. A physics equation of motion is utilized to solve it by inserting the values and extracting time.

Explanation:

The subject of the question is physics, specifically the subtopic of kinematics in terms of upward motion. The problem can be solved by using the equation of motion: `y = y0 + v0 * t - 0.5 * g * t²`, where y0 is the initial height, v0 is initial velocity, g is the acceleration due to gravity and t is the time taken. In this situation:

y0 is 1 meter (the starting height of the ball).
v0 is 13 m/s (the initial upward velocity of the ball).
g is approximately 9.8 m/s² (the acceleration due to gravity).

Set y (the final position) to 0 (ground level), and solve for t (time taken):

0 = 1m + (13 m/s) * t - 0.5 * (9.8 m/s²) * t²

Solving this quadratic equation, we get two solutions as the time cannot be negative for this context, so choose the positive value as the time taken for the ball to hit the ground. This will give the duration the volleyball remains in the air after being hit by Martina.

Hello Its 700 Glad To Help! :)

Order this starting from the smallest:15.249 15.3 15.05 15.009 15.25

Answers

i think it might be easier to understand if i change decimals to fractions, so lets start ;)
$15.249=15(249)/(1000)$
$15.3=15.300=15(300)/(1000)$
$15.05=15.050=15(50)/(1000)$
$15.009=15(9)/(1000)$
$15.25=15.250=15(250)/(1000)$

denominators are the same so now you only have to compare numerators (biger numerator = greater fraction)

so:

$15(9)/(1000)<15(50)/(1000)<15(249)/(1000)<15(250)/(1000)<15(300)/(1000)$

it means that:

$15.009<15.05<15.249<15.25<5.3$

15.009
15.05
15.249
15.25
15.3

Cindy needs to order 150 invitations which are sold in packs of 20. How many packs does Cindy need to buy?A) 6
B) 7
C) 8
D) 9

Answers

The question is an illustration of divisions.

Cindy needs to buy (c) 8 packs

The given parameters are:

$\mathbf{Invitation = 150}$

$\mathbf{Pack = 20}$

The number of packs is calculated by dividing the total number of invitation by the number of invitations in each pack.

So, we have:

$\mathbf{n = (Invitation)/(Pack)}$

$\mathbf{n = (150)/(20)}$

$\mathbf{n = 7.5}$

Cindy needs 7.5 packs.

Since the packs cannot be split, Cindy must buy the closest number of packs greater than 7.5

So, we have:

$\mathbf{n = 8}$

Hence, Cindy needs to buy (c) 8 packs

-6x + 12

To find this answer, follow these steps:

First, multiply 2x + 3 and x - 6 using either the FOIL method or the box method. This should get you the answer of 2x^2 - 9x - 18

This should now replace the 2x + 3 and x - 6

So with that, you should have this currently:

2x^2 - 9x - 18 - 2x^2 + 3x + 30

Now, combine like terms:

The 2x^2 cancels each other out. After that, combine -9x and 3x to get -6x. Then -18 and 30.

This should leave you with the final answer of -6x + 12

Hope this helps!
