The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=\frac{7}{9}x^2+3

as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3 

the equation can be written as :\frac{x^2}{25}+ \frac{y^2}{9} =1

Find the distance between line 11x-60y-15=0 and point (2, 1/60)
vovikov84 [41]

Answer:

The answer to your question is: d = 6 / 61 or 0.1 units

Step-by-step explanation:

Data

Line: 11x - 60y - 15 = 0   A = 11; B = -60; C = -15

Point (2, 1/60)                 x = 2    y = 1/60

Formula

d = | Ax + By + C | / √(A² + B²)

Process

d = | (11)(2) + (-60)(1/60) -15 | / √(11² + (-60²)

d = | 22 -1 - 15 | / √ 121 + 3600

d = | 6 | / √3721

d = | 6 | / 61

d = 6 / 61 or 0.1 units

3. Two dice are rolled. What’s the conditional probability that both dice are 5’s if it’s known that the sum of points is divisi
ArbitrLikvidat [17]

Answer:

Pr =\frac{1}{3}

Step-by-step explanation:

Given

S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)

(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)\} --- sample space

First, list out all outcomes whose sum is divisible by 5

A = \{(4,6), (5,5),(6,4)\}

So, we have:

n(A) = 3

Next, list out all outcomes that has an outcome of 5 in both rolls

B = \{(5,5)\}

n(B)  =1

The required conditional probability is:

Pr =\frac{n(B)}{n(A)}

Pr =\frac{1}{3}
