Use the image below to answer the following question. Find the value of sin x^0 and cos y^0. What relationship do the ratios of
gregori [183]

Answer:

sin x = 3/5

cos y  = 3/5

sin x and cos y are equal

Step-by-step explanation:

First we need to find the length of the hypotenuse

We can use the Pythagorean  theorem

a^2+ b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 +8^2 = c^2

36+64 = c^2

100 = c^2

Taking the square root

sqrt(100) = sqrt(c^2)

10 = c

The hypotenuse is 10

Since this is a right triangle we can use trig functions

sin x = opp side/ hypotenuse

sin x = 6/10 = 3/5

cos y = adj / hypotenuse

cos y = 6/10  = 3/5

sin x and cos y are equal

What is the slope of the line?<br><br>1<br>1/2<br>-2<br>2​
Ray Of Light [21]

Answer:

2

Step-by-step explanation:

The slope of the line is 2. The slope is rise over run, or change in y over change in x. So to find the slope count how much each value changes, in this graph y changes +2 and x changes +1. So the slope is 2/1 or just 2. One way to visually check the slope is to remember fraction slopes will make the line flatter and other whole numbers make the line steeper.

How do you solve this ?
Burka [1]
There is a rather-hard-to-remember formula for the lateral area of a cone.  I'd suggest you look that up on the 'net.  Here you have a right circular cone with radius 24/2, or 12 units and slant height 36 units.  If you're unable to find the formula on your own, come back and I'll give you some hints.
