To solve this problem youu must apply the procedure shown below:
1. Let's call (x0, y0) to any point of the parabola.
2. Then, you have:
√(x0-a)^2+(y0-b)^[2=|y0-10|
3. When you susbtitute values and simplify it, you obtain:
(√(x0-4)^2+(y0-0)^2)^2=(y0-10)^2
(x0-4)^2+y0^2=(y0-10)^2
4. Now, you must clear y, and you will have:
y=(-x^2/20)+(2x/5)+(21/5)
Answer:
70%
Step-by-step explanation:
Universal set = set of all first year students
P(U) = 1
P(M) = 0.5
P(B) = 0.4
P(M n B) = 0.2
The percent of first year college students take either mathematics or biology or both
P(M U B) = ?
P(M u B) = P(M n B') + P(M' n B) + P(M n B)
P(M n B') = P(M) - P(M n B) = 0.5 - 0.2 = 0.3
P(M' n B) = P(B) - P(M n B) = 0.4 - 0.2 = 0.2
P(M u B) = 0.3 + 0.2 + 0.2 = 0.7 = 70%
Y=2x+7
y=mx+b (slope-intercept form)
First, solve for y.
2y= 4x+14 (added 4x to both sides to cancel and single out the y)
y= 2x+7 (divided both sides by 2, since I only need the y)
3.14 by 3.57 ; divide 44 and 50 by 14 and round to the hundredths place
