The answer:
the complement of the question proposed one of the choices given beneath:
a) 58.8
b) 53.0
c) 29.4
d) 26.5
as we observe at the figure, AOB an isosceles triangle, and OCB is a right triangle
consider OCB
OC =9, OB= radius = 28
the problem is how to find the length of CA, for that C is a midpoint of segment AB, so AC=BC
BC can be found by using pythagorean theorem
OB²= OC² + CB², this implies CB² = OB² - OC²
CB² = 28² - 9² = 784 - 81=703, therefore CB= sqrt (703)=26.51
CB=26.51, since CB= AC, so AC=CB= 26.51
finally the <span>the length of AB is AB = 2 x CB = 2x AC= 2x 26.51= 53.0
</span>
the answer is b) 53.0
An x-intercept is namely a "solution" or "zero" or "root" often called, and when that happens, y = 0, just like with any other x-intercept.
so what is its x-intercept anyway?
This is the leineae making it a because it’s cubic
Answer:
35triangles
Step-by-step explanation:
Given
Total distinct points = 7
If we are to form triangles using the dots,
Total points in a triangle = 3
Using the combination rule;
number of triangles formed = 7C3
7C3 = 7!/(7-3)!3!
7C3 = 7!/4!3!
7C3 = 7*6*5*4!/4!3!
7C3 = 7*6*5/6
7C3 = 7*5
7C3 = 35
Hence the amount of triangles that can be formed is 35triangles
