The answer is 90, 25, 155, 115 respectively
Step-by-step explanation:
If the parabola has the form
(vertex form)
then its vertex is located at the point (h, k). Therefore, the vertex of the parabola

is located at the point (8, 6).
To find the length of the parabola's latus rectum, we need to find its focal length <em>f</em>. Luckily, since our equation is in vertex form, we can easily find from the focus (or focal point) coordinate, which is

where
is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length <em>f</em> is

By definition, the length of the latus rectum is four times the focal length so therefore, its value is

Answer:
125
Step-by-step explanation:
x(t) = x0 × (1 + r) t
where:
x(t) = the amount of some quantity at time t
x0 = initial amount at time t = 22
r = the growth rate
t = time
Answer: 129
Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr² (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)
Area=3.14(5)²
=3.14(25)
=78.5
But since this is just a half circle, divide this by 2
That will get 39.25
Then add this to the area of the rectangle (L*W) which is 90
That will get about 129
Answer:
A = 16010.32
Step-by-step explanation:
Given that,

Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.

So, the value of A is 16010.32. Hence, the correct option is (B).
