1500-125=1,375
so 1375 should be your answer.
Answer: (0,0)
Step-by-step explanation:
I'm pretty sure it's <em>C</em>
Step-by-step explanation:
2/3=8/12
8/12 ....divided both by 4=2/3
2/3=2/3
A. The drop-out rate can be estimated using the equation,
d = my + b
where d is the drop-out rate, m is the slope of the line, y is the number of years from 1998 and b be the initial value. For 2008,
18.3 = m(2008 - 1998) + 38.46
The value of m from the equation is -1.12. The equation becomes,
d = -1.12y + 38.46
b. The vertical intercept of the model is when d is equal to zero.
0 = -1.12y + 38.46
The value of y from the equation is 34.34.
(34.34, 0)
c. n = 1990 + 34.34 = 2024.34.
The vertical intercept of this problem tells me that by the year 2024, the drop-out rate would be 0%.
Answer:
The diameter of the circumscribed circle is 6.92
Step-by-step explanation:
In the question, we are asked to calculate the diameter of a circle, which has a an equilateral triangle inscribed in it.
To solve this problem, let us consider the diagram attached.
Now let’s assume the point o is the center of the circle and that r is the radius of the circle. Now to calculate this radius, we need to employ the use of a trigonometrical ratio.
According to the question, we can see that we have the adjacent and the hypotenuse, so the trigonometric identity to use is the cosine.
Mathematically;
Cosine 30 = 3/r
r = 3/cosine 30
Cosine 30 = 0.866
r = 3/0.866
r = 3.46
But in the question, we were asked to calculate the diameter and not the radius.
Mathematically; d = 2r = 2 * 3.46 = 6.92
