Answer:
Explanation:
You draw a vertical line going upward from<em> x = -1</em>, stop where your vertical line intercetpts the <em>function</em> (the red line); then draw a horizontal line unitl you reach the y-axis; finally, you can read the y-value on the y-axis. That is the value of the function.
It is pretty close to the midpoint between y = 1 and y = 2, thus a good estimate would be y = 1.5.
Csc 0 = r/y
r = sqrt 81 + 144
r = sqrt 225
r = 15
csc 0 = 15/12
Answer:
see below
Step-by-step explanation:
We need to find the diameter of the square
We can find this using the Pythagorean theorem
a^2+b^2 = c^2 where the legs are 7 and 7 and the diameter is c
7^2 +7^2 = c^2
49+49 = c^2
98 = c^2
Taking the square root of each side
sqrt(98) = sqrt(c^2)
9.899494937 = c
Since 9.9 is less than 11 which is the diameter of the circle it will never touch the circle.
Since the longest part of the square is less than the diameter of the circle, the square will fit inside the circle without touching

60 min = 1 hour
1st we need to know how many times 20 goes in 60 so we will divide.
60 ÷ 20 = 3
Now we will multiply to find the trains speed in miles per hour.
3 × 25 = 75
SO, the train travels 75 miles per hour.
Hope I helped ya!!
