First you have to figure out 15% of 900 so .15 times 900 which is 135 so then you do 900+135 which is now 1035

The range of a projectile that is launched with an initial velocity v at an angle of a with the horizontal is given by R

lara31 [8.8K]

Answer:

$\theta=30.285^{\circ}$

Step-by-step explanation:

The range of a projectile is given by :

$R=\dfrac{u^2\sin2\theta}{g}$

Put R = 20 m, u = 15 m/s and finding the value of angle of projection

So,

$R=\dfrac{u^2\sin2\theta}{g}\\\\\sin2\theta=\dfrac{Rg}{u^2}\\\\\sin2\theta=\dfrac{20\times 9.8}{15^2}\\\\\sin2\theta=0.871\\\\2\theta=\sin^{-1}(0.871)\\\\2\theta=60.57\\\\\theta=30.285^{\circ}$

So, the required angle of projection is equal to $30.285^{\circ}$ .

Simplify: -6(x + 4)

Bess [88]

Answer:

A) -10x - 24

Step-by-step explanation:

1. To simplify this expression, we apply the distributive property.

$(-6)(\frac{5}{3}x)+(-6)(4)$
$\frac{-30}{3}x-24$
$-10x - 24$

Therefore, the answer is A) -10x - 24.

Can someone pls help me with number 5 pls show your work so i can understand thanks

Natali [406]

Step-by-step explanation:

Let's represent Aaron's age with x and

Charlene's age with x+8

x+x+8=44

2x+8=44

2x=44-8

2x=36

x=36÷2

x=18

Aaron is 18 years old.

While Charlene is 18+8=26 years old.

Find the measure of angle y. Round your answer to the nearest hundredth. Right triangle

e-lub [12.9K]

<h3>The measure of angle y is 35.68 degrees</h3>

<em><u>Solution:</u></em>

Given that,

hypotenuse 12

Opposite 7

Find the measure of angle y

y is unknown and is between the hypotenuse and adjacent side

The figure is attached below

In a right triangle, the sine of the angle is the ratio of the side opposite to the angle to the hypotenuse

Therefore,

$sin\ y = \frac{opposite}{hypotenuse}\\\\sin\ y = \frac{7}{12}\\\\sin\ y = 0.5833\\\\y = sin^{-1}\ 0.5833\\\\Use\ arcsin\ calculator\\\\y = 35.6829 \\\\y \approx 35.68$

Thus measure of angle y is 35.68 degrees
