The focus of a parabola does not lie on it. Hence, the equation of parabola is given as y² = 2y - x².

The parabola can be defined as a conic section curve, all of whose points are equidistant from a fixed point called as focus and a fixed line called as directrix.

Given that,

The focus of parabola is (0, 1).

The vertex of parabola is (0, 0).

Suppose, there is one more point on parabola as (x, y).

Since focus of a parabola is equidistant from all the points on parabola.

Use distance formula to find the distance between two points (x₁, y₁) and (x₂, y₂) as √((x₂ - x₁)² + (y₂ - y₁)²) to find the equation of parabola as,

√((x - 0)² + (y - 1)²) = √((0- 0)² + (0 - 1)²)

=> x² + (y - 1)² = 1

=>  (y - 1)² = 1 - x²

=> y² - 2y + 1 = 1 - x²

=> y² = 2y - x²

Hence, the equation of the parabola having vertex at origin and focus at  (0, 1) is  y² = 2y - x².

The value of k in this exponential decaying situation of radioactive material is  - 0.0069.

One of the key mathematical operations is the exponential function we allow the exponent to be the independent variable to create an exponential function.

Given, An equation of the form y = y₀e^(kt) models a situation of decaying radioactive material.

y₀ = 10mg, half-life = 100 days.

So, in 100 days the left-out radioactive material will be 5mg.

∴ 5 = 10.e^(100k).

e^(100k) = 1/2.

lne^(100k) = ln(1/2).

100k = - 0.69

k = - 0.69/100.

Answer:factor of x³ + 343

Step-by-step explanation: Option D is correct. A factor of an expression is usually referred to as a number or an algebraic expression that divides the known expression. The above algebraic expression needs to be expanded to determine its factor; Mathematically; x³ + 343 = (x + 7) (x² - 7x + 49) Therefore, we can conclude that the factors are (x + 7) (x² - 7x + 49)

We fail to reject the null hypothesis and there is no significant evidence for the manager to conclude that the standard deviation has decreased at the α = 0.01

What is standard deviation?

The standard deviation is a statistic that expresses the degree of variation or dispersion among a group of data. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the mean of the collection.

The null and alternative hypotheses are:

[tex]H_{0} :[/tex] α = 0.004

[tex]H_{a} :[/tex] α < 0.004

Under null hypothesis, the test statistic is:

[tex]x^{2} = \frac{(n-1)s^{2} }{\alpha ^{2} }[/tex]

   = (29 - 1)0.0036² / 0.004²

   = 22.68

Now the critical value of x² at 0.01 level of significance for

df = n-1

  = 29 - 1

 = 28

[tex]x_{critical} ^{2}[/tex] = 48.278

Since the test statics

x² = 22.68 is less than the critical value

[tex]x_{critical} ^{2}[/tex] = 48.278

Answer:

A, B, F

Step-by-step explanation:

Well, to do this let's start by simplifying each of the ratios! If they can be simplified to 8:2 then they are a match

A: 16:4

Divide both sides by 2: 8:2 (This is an answer)

B: 40:10

Divide both sides by 5: 8:2 (This is also an answer)

C: 2:8

This one is not possible, because you would have to multiply the 2 by a whole number, and the 8 by a number less than one. Both have to be multiplied/divided by the same number.

D: 10:4

To get the 4 into a 2, we divide by 2. If we divide the 10 by 2 we get 5. Thus, this is not an answer.

E: 1:6

To get the 6 into a 2, we must divide it by 3. If we divide 1 by 3, we get a decimal, not 8.

F: 4:1

Multiply both sides by 2: 8:2 (This is our final answer)

Using the compound interest formula, we have:

Answer: 19/24

Explanation:

From the information given,

Number of green marbles = 15

Number of red marbles = 9

Total number of marbles = 15 + 9 = 24

Probability is expressed as

number of favorable outcomes/number of total outcomes

Probability f selecting a greeen marble = 15/24

Even numbers divide 2 without a remainder. The even numbered marbles are

red = 2, 4, 6, 8

green = 2, 4, , 68, 10, 12, 14

Total number of even numbered marbles = 11

Probability of selecing an oevennumber = 10124

The events are not mutually exclusive becuse they can occur together. For two ebvents, A and B that are not mutually exclusive,

P(A U B) = P(A) + P(B) - P(A and B)

Thus,

the probability that the marble is green or even numbered = Probability of selecting a green marble + Probability of selecting an even number - Probability of selecting a green and even numbered marble

Number of green even numbere marble s = 7

Probability of selecting a green and even numbered marble = 7/24

Thus,

the probability that the marble is green or even numbered = 15/24 + 11/24 - 7/24

the probability that the marble is green or even numbered = 19/24

Answer:

Step-by-step explanation:

equation of finding a midpoint is (x2+x1)/2 and (y1+y2)/2

7) (4+12)/2 = 8 and (9+-4)/2= 2.5

hence midpoint is (8,2.5)

8) we are told the midpoint so we can now find the co-ordinates of the other endpoint:

(5+x)/2= -3

rearrange to find x--> 5+x =-6, so x=-11

(-7+y)/2=2

rearrange to find y--> -7+y=4, so y=11

other endpoint: (-11,11)

5) the gradient of the new equation is parallel to y=3x+7 so it will stay the same

y=3x+c

we know that the points this line passes through is: (-4,-8) so we substitute this into our new equation to find c

-8= (3 x -4) +c

-8=-12 +c

so c= 4

Hence our new equation is y=3x+4

6) perpendicular gradient means that our existing gradient needs to be reciprocated (turned into negative and then flipped)

new gradient is -1/3

y=-1/3x+c

we know the value for x and y so we can substitute into our new equation to find c

9=(-1/3 x -6) +c

9=2 + c

c= 7

Hence our new equation is y=-1/3x+7
