Answer:
A and B
Step-by-step explanation:
It's definitely not equilateral or isosceles because none of the side lengths are equal. Therefore, it is scalene. Since all of the angles are acute, it's not obtuse or right, therefore it is acute.
Left side is 22.
22 x 10 = 220
(20 - 6) x 12 = 168
6 x 20 = 120
220 + 168 + 120 = 508
Thank you very much.
Answer:
Step-by-step explanation:
The best way to answer a question like this one is to use a graphing program on the internet. This graph was done with desmos
It looks to me that the equation is g(x) = 10(x - 5)^2 - 37
I checked to see that this is correct, and thank goodness it is.
- The vertex of the graph is (5, -37).
- The vertex has a minimum
- The parabola opens upward
The graph is shown below.
Answer:
x ≈ 83.7
Step-by-step explanation:
You are given a right triangle with the hypotenuse, an acute angle, and the side adjacent to the angle marked. The hypotenuse is unknown. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
Filling in the given information, we have ...
cos(48°) = 56/x
x = 56/cos(48°) . . . . . multiply by x/cos(48°)
x ≈ 83.7
Answer:
0.9545
Step-by-step explanation:
Use a calculator with probability distribution functions.
Here we'd use normcdf( ).
normcdf(300,700,500,100) = approximately 0.9545
