A shooting star forms a right triangle with the Earth and the Sun, as shown below:

Mathematics

frez [133]3 years ago

The positions of the sun, earth and shooting star form a right angled triangle, where distance between earth and sun is 'y', and the angle 'x°' is given

Now, in a right angled triangle using trigonometry, we can determine a side of the triangle is one of the sides and one of the angles is known

Here, if we use cos x = \frac{Base}{Hypotenuse} we can determine the distance between the shooting star and the sun. This can be done because we know that the base is 'y', the angle is x° and the hypotenuse represents the distance between the sun and the shooting star

Note: cos values for each x are definite.

-4

Step-by-step explanation:

-4z² + z²

let's assume you have z² and you're owing 4z², you'll pay the z² you have and you'll still owe 4

so that is -4

A gas container in the shape of a cone has a height of 12 inches and a maximum diameter of 8 inches. When the container is fille
Nady [450]

Answer:

150.9 cubic inches

Step-by-step explanation:

volume of he gas = volume of a cone x 3/4

Volume of a cone 1/3(nr^2h)

n = 22/7

r = radius  

h = height

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

8/2 = 4 inches

1/3 (22/7 x 4^2 x 12) = 201.142857 in^3

volume of the gas = 3/4 x 201.142857 in^3 = 150.9 in^3

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Write an equation in slope-intercept form for the line with slope -5 and y-intercept 3. Then graph the line.
kumpel [21]

The slope-intercept form for the line with slope -5 and y-intercept 3 is,

y= -3x+5.

What is the slope-intercept form of a line?

The conventional form Ax + By = C and y= mx + b have been used to describe linear equations. The slope-intercept form y = mx + b will now be the focus of our attention.

You can write a linear function using the slope of the line and the y-intercept in the slope-intercept form.

y=mx+b

Where b is the y-intercept and m is the slope.

A straight line's slope-intercept equation is written as y=mx+b, where m denotes the slope and b is the y-intercept.

In this case, m=3 and b=5 and y=3x+5 y=3x+5 is the necessary equation.

Hence,The slope-intercept form for the line with slope -5 and y-intercept 3 is,

y= -3x+5.
