Hi. Unfortunately there is no statement to determine if it's true or not. However, I would just give the correct statement.
Secant function is the inverse of cosine. In trigonometry, a right triangle has one 90 degrees angle. It consists of the hypotenuse(h), the adjacent side (a), and the opposite side(o), with respect to the angle. For cosine, it is adjacent over hypotenuse. Since secant is the inverse, it would be hypotenuse/adjacent. Hypotenuse is the longest side.
Hence, sec theta = 15/9
I hope this helps :)
Answer:
Option B.
Step-by-step explanation:
Obvious. <u>Lets explain:</u>
<em>Option A: It's pretty ease to do. You just need 2 triangles to make a parallelogram, and that's that.</em>
<em>Option B: How can you make a rectangle from triangles-???</em>
<em>Option C: You might think I am wrong, but I am right. Get 6 triangles, then plato, you have a whole hexagon!</em>
<em>Option D: You probably already know this...but you just need three triangles.</em>
It's correct on every school thing.

A scale factor is a number which scales, or multiplies, some quantity.
Answer:
0.6247
Step-by-step explanation:
In order to find the frequency of people who complete the test between 45 and 65 minutes, we have to find z
Z = (x – mean)/standard deviation
Le x be the time to complete the test
Z1 = (45 – 60)/10 = -1.5
Z2 = (65 – 60)/10 = 0.5
Then we use the z table to find the area under the curve.
Area for Z1 = 0.4332
Area for Z2 = 0.1915
The relative frequency is the area between the two z-scores:
0.4332 +0.1915 = 0.6247

Answer:
37%
Step-by-step explanation:
Surface area of a cylinder = πr² + 2πrh
With r = 22 and h = (6 + 10) = 16
Area = π * 22² + 2 * π * 22 * 16
Area = 1520.728 + 2211.968
Area = 3732.696 in²
Percentage of green = surface area of green ÷ total surface area
Surface area of green = 2πrh
Surface area of green = 2 * π * 22 * 10
Surface area of green = 1382.48
Percentage of green = 1382.48 / 3732.696 * 100%
Percentage of green = 37%
