Suppose a parabola has a vertex (5,-3) and also passes through (6,1). Write the equation of the parabola in vertex form

Answers

Answer 1
so hmmmm let's assume is a vertical parabola, so, the squared variable will  then be the "x".

[tex]\bf \qquad \textit{parabola vertex form}\\\\ \begin{array}{llll} \boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\ x=a(y-{{ k}})^2+{{ h}} \end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\ -------------------------------\\\\ \begin{cases} h=5\\ k=-3 \end{cases}\implies y=a(x-\stackrel{h}{5})^2\stackrel{k}{-3} \\\\\\ \textit{now, we also know that } \begin{cases} x=6\\ y=1 \end{cases}\implies 6=a(1-5)^2-3 \\\\\\ 9=a(-4)^2\implies 9=16a\implies \cfrac{9}{16}=a\qquad thus\quad \boxed{y=\cfrac{9}{16}(x-5)-3}[/tex]
Answer 2

The equation of the parabola with vertex (5, -3) and passing through (6, 1) in vertex form is y = [tex]4(x - 5)^2 - 3.[/tex]

To write the equation of a parabola in vertex form, we use the formula:

y = [tex]a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola. Given the vertex (5, -3) and a point (6, 1) the parabola passes through, we can plug these values into the equation to find a.

For the point (6, 1):

[tex]1 = a(6 - 5)^2 - 3[/tex]

[tex]1 = a(1)^2 - 3[/tex]

4 = a

So, the equation of the parabola in vertex form is:

y = [tex]4(x - 5)^2 - 3[/tex]

Three boys share 28 toy cars equally. How many cars did each boy get and how many were left over

Answers

Divide 28 by 3 and count how many are left over.

28 / 3 = 9 1/3

So each boy had 9 toy cars, and because you can't have 1/3 cars, you round 1/3 to 1. So there was 1 left over car.

A random variable x takes four possible values, 0, 2, a, and b, where a and b are unknown numbers. if pr[x = 0] = 0.2, pr[x=2] = 0.4, pr[x = a] = 0.3, e[x] = 2.8 and it is the case that a + b = 6, what is the missing value of a ?
a.-1.0
b.5.0
c.7.0
d.cannot be determined without more information
e.none of the above

Answers

Final answer:

The missing value of the random variable X can be determined by solving the equation e[x] = 2.8 and substituting the known values. By solving the equation, we find that the missing value is c. 7.

Explanation:

a. In words, X = A random variable that takes four possible values: 0, 2, a, and b.

b. X~ A missing value that represent an unknown number for the random variable X.

c. In words, X = The missing value of the random variable X, denoted by a.

d. X A missing value that we need to determine.

In this case, the missing value of a can be found by substituting the known values into the equation a + b = 6. Since b = 6 - a, we can substitute this expression into the equation e[x] = 2.8 and solve for a. From the equation, we get 0.2(0) + 0.4(2) + 0.3(a) + 0.3(6 - a) = 2.8.

Solving this equation gives us a = 7. Therefore, the missing value of a is 7, so the correct answer is c.

Anjali went to Citizens Bank and borrowed $7,000 at a rate of 8%. The date of the loan was September 20. Anjali hoped to repay the loan on January 20. Assuming the loan is based on ordinary interest, Anjali will pay back how much interest on January 20?      A. $187.18 B. $187.17 C. $189.78 D. $188.22

Answers

From September 20 to January 20, there are 4 months only which is equivalent to 1/3 of a year. The interest earned by the investment, P, made is calculated 
               I = P x i x n
where I is the interest, P is the principal amount, i is the interest rate, and n is the number of years. Substituting the known values,
                I = ($7000)(0.08)(1/3)
                I = $186.67
Hence, the answer to this item is $186.67. 

Answer:

$189.78

Step-by-step explanation:

"The computation of the interest on January 20 is shown below:

= Principal × interest rate × number of days ÷ total number of days in a year

= $7,000 × 8% × 122 days ÷ 360 days

= $7,000 × 8% × 0.338

= $189.78

The 122 days are calculated below:

September - 10 days

October - 31 days

November - 30 days

December - 31 days

January  - 20 days

Total    - 122 days

And we assume the 360 days in a year"

If p(a) = 0.25 and p(b) = 0.65, assuming independence of events, then p(a and

Answers

0.25x0.65=0.1625
full answer

The Independent events is 0.1625.Events A and B are considered independent if the likelihood of each event's occurrence is unaffected by the occurrence of the other.

Find the independent events?

P(A/B) is equal to P(A.B)/P(B) by definition (A). P(A) = P(B) / P(B) (as A, B are Independent events).

Events A and B are considered independent if the likelihood of each event's occurrence is unaffected by the occurrence of the other. P(A) = P(AB) = 1/2, which suggests that the likelihood of event A occurring has not changed as a result of the occurrence of event B.

P(0.25) = P(0.25 * 0.65) = 1/2

P(0.25) = 0.1625.

The Independent events is 0.1625 .

Answers

The answer is the option B. rotate 90 degrees counterclokwise and then rotate 270 degrees counterclockwise.

See that two consecutive rotations counterclockwise are equivalent to one single roration counterclockwise as long as the angles sum up the same.

Given that 90° + 270 ° = 360° means that the two rotaions are equivalent to one 360° rotation, and so the final figure will be the same as the original figure.

What is the y-intercept of the line given by the equation y = 5x - 21?

Answers

To find the y-intercept of y = 5x - 21, identify the constant term of the equation, which is -21, indicating the y-intercept is -21.

The y-intercept of the line given by the equation y = 5x - 21 can be found by analyzing the equation in the form y = mx + b, where m is the slope and b is the y-intercept.

Comparing the equation y = 5x - 21 with y = mx + b, we see that the y-intercept is -21 (b = -21).Therefore, the y-intercept of the line y = 5x - 21 is -21.

justin sold 300 liter of soda at a baseball game.how much is this in milliliters?

Answers

If Justin sold 300 liters of soda, then he would have sold 300000 milliliters of soda. 1 liter= 1000 milliliters

Answer:

300,000 mililiters

Step-by-step explanation:

Remember that in international system the convertions are really easy because they are done 10 by 10, so from liters to mili, there are 3 spots, 1000, so there are 1000 mili-liters in a liter, so you just need to multiply the 300 liters of soda by 1000, which is 300,000 mililiters and that is what Justin sold at the baseball game in mililiters.

Find all the local maxima, local minima, and saddle points of the function

Answers

what function can you post it please and thank you

Final answer:

To find local maxima, minima, and saddle points, find critical points using the first derivative test and then apply the second derivative test.

Explanation:

To find the local maxima, local minima, and saddle points of a function, we first need to find the critical points. These are the points where the derivative of the function is either zero or undefined. To check whether each critical point is a local maxima, local minima, or saddle point, we use the second derivative test.

The second derivative test states that if the second derivative is positive at a critical point, then the point is a local minimum. If the second derivative is negative, then the point is a local maxima. If the second derivative is zero, the test is inconclusive.

By applying the second derivative test to each critical point, we can determine whether it is a local maxima, local minima, or saddle point.

Solve the system of linear equations. separate the x- and y- values with a coma. 20x=-58-2y

Multiply second equation by -1
20x = -58 - 2y
-17x = 49 + 2y
Add equations.
3x = -9 
Divide.
x = -3
Plug in -3 into one of the equations.
17(-3) = -49 - 2y
-51 = -49 - 2y
Add 49 to both sides.
-2 = -2y

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 20 miles per hour faster than the westbound train. If the two trains are 750 miles apart after 5 hours, what is the rate of the eastbound train?

Answers

east bound train = x

westbound train = x-20 ( 20 miles slower than east bound)

5x + 5(x-20) = 750

5x +5x -100=750

10x -100 = 750

10x =850

x = 850/10 = 85

east bound train is 85 mph

west bound train is 85-20 = 65 mph


check: 85*5 = 425

65*5 = 325

325+425 = 750

A food truck sells salads for $6.50 each and drinks for $2.00 each. The food truck’s revenue from selling a total of 209 salads and drinks in one day was $836.50. How many salads were sold that day? A) 77 B) 93 C) 99 D) 105

Answers

Create an equation to figure out how much salad was sold that day. S is for the number of salads. D is for the number of drinks.

$6.5s + $2d = $836.5
s + d = 209
s = 209 - d

Plug in the values. 

6.5 (209 - d) + 2d = 836.5

1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116

s = 209 - 116

Find the limit, if it exists. (if an answer does not exist, enter dne.) lim (x, y) → (0, 0) x4 − 20y2 x2 + 10y2

Answers

Traveling along the x-axis, we have

[tex]\displaystyle\lim_{(x,y)\to(0,0)}\frac{x^4-20y^2}{x^2+10y^2}=\lim_{x\to0}\frac{x^4}{x^2}=\lim_{x\to0}x^2=0[/tex]

On the other hand, along the y-axis we get

[tex]\displaystyle\lim_{(x,y)\to(0,0)}\frac{x^4-20y^2}{x^2+10y^2}=\lim_{y\to0}\frac{-20y^2}{10y^2}=\lim_{y\to0}(-2)=-2[/tex]

Therefore the limit doesn't exist.
Final answer:

The limit of the expression as (x, y) approaches (0, 0) does not exist.

Explanation:

To find the limit as (x, y) approaches (0, 0) of the expression \(\frac{x^4 - 20y^2}{x^2 + 10y^2}\), we can try approaching the limit along different paths. Let's consider approaching along the x-axis (y=0) and along the y-axis (x=0) separately.

Approaching along the x-axis: \(\lim_{{(x, 0) \to (0, 0)}} \frac{{x^4 - 20(0)^2}}{{x^2 + 10(0)^2}} = \lim_{{(x, 0) \to (0, 0)}} \frac{{x^4}}{{x^2}} = \lim_{{(x, 0) \to (0, 0)}} x^2 = 0.

Approaching along the y-axis: \(\lim_{{(0, y) \to (0, 0)}} \frac{{(0)^4 - 20y^2}}{{(0)^2 + 10y^2}} = \lim_{{(0, y) \to (0, 0)}} \frac{{-20y^2}}{{10y^2}} = \lim_{{(0, y) \to (0, 0)}} -2 = -2.

Since the limit approaches different values along different paths, the limit does not exist.
