Work out the area of triangle ABC<br> 2 root 5 cm <br> 3 root 2 cm

A ball is thrown with an initial speed of 17 mph in a direction that makes an angle of 22 degrees with the positive x-axis. Expr

Agata [3.3K]

Answer:

The speed of the ball in terms of i and j is (15.76 i, 6.37 j)

Step-by-step explanation:

Given;

velocity of the ball, v = 17 mph

angle of inclination, θ = 22⁰

The horizontal component of the velocity is calculated as;

$V_x = Vcos\theta\\\\V_x = 17cos(22)\\\\V_x = 15.76 \ i$

The vertical component of the velocity is calculated as;

$V_y = Vsin\theta\\\\V_y = 17sin(22)\\\\V_y = 6.37 \ j$

Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)

Geometry question, I need help with this.

yaroslaw [1]

<u>1st transformation:</u> A vertical translation of the figure down by 8 units

<u>2nd transformation: </u>Shows a reflection on both axis and vertical translation up the plane by 8 units

<h3>Transformation of coordinates</h3>

Transformation is a way of changing the position of an object on an xy-plane.

For the translation

(x, y)-> (x, y-8)

It shows a vertical translation of the figure down by 8 units while the translation;

(x, y - 8) -> (-x, -y)

shows a reflection on both axis and vertical translation up the plane by 8 units

Help pleaseeeeeeeeee

Alex17521 [72]

Answer:

39°
27°
28°

Step-by-step explanation:

1.

$Hypotenuse = 32\\Adjacent = 25\\Angle\:\alpha \:=?\\Using \: SOHCAHTOA ;\\Cos \:\alpha = \frac{adj}{hyp} \\Cos \:\alpha = \frac{25}{32}\\\\\alpha = Cos^-^1\frac{25}{32} \\\alpha =38.62\\\\\alpha = 39$

2.

$Opposite = 8\\Adjacent = 16\\\alpha =?\\Using SOHCAHTOA\\Tan\:\alpha = \frac{opp}{adj} \\Tan\:\alpha = \frac{8}{16} \\Tan \:\alpha =1/2\\\alpha = Tan^-^11/2\\\\\alpha =26.56\\\alpha =27$

3.

$Hypotenuse = 41\\Opposite = 19\\\alpha = ?\\Using\: SOHCAHTOA\\Sin\:\alpha = \frac{opp}{hyp} \\Sin \:\alpha =\frac{19}{41}\\\\\alpha =Sin^-^1 (19/41)\\\\\alpha =27.6\\ \alpha =28$

How do you find the area of this

zlopas [31]

Answer:

2345 units^2

Step-by-step explanation:

First, you can use Soh Cah Toa to find line c to be 36*sqrt(2). Furthermore, you can use the same equation to find the other sides to be both 65.15. To further solve, you just need to multiply 65.15 by 36 to get a final answer of 2,345.4 units^2
