What does the graph of Ax)=-(x-3)* +11 look like?


A. opens downward with a vertex of (3, 11)
B. opens downward with a vertex of (-3, 11)
C. opens upward with a vertex of (3, 11)
D. opens upward with a vertex of (-3, 11)

Answers

Answer 1

Answer:

  A.  opens downward; vertex (3, 11)

Step-by-step explanation:

The leading coefficient is negative (-1), so we know the parabola opens downward.

The vertex in the form ...

  A(x) = a(x -h)² +k

is (h, k). Comparing to the given equation, we find (h, k) = (3, 11).

The vertex is (3, 11).

Find the sum of the geometric series 1−0.99+0.99^2−0.99 ^3 +...−0.99

Answers

Answer:

0.28

Step-by-step explanation:

The sum of the geometric value progression is S = 0.28

What is Geometric Progression?

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the sequence be A = { 1 - 0.99 + 0.99² - 0.99³... - 0.99⁷⁹ }

So , A = 1 - { 0.99 - 0.99² + 0.99³... + 0.99⁷⁹ }

Let the first term of the GP be a₁ = 0.99

Now , the common ratio of GP , r = 0.99

And , the number of terms in GP = 80

And , Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

On simplifying , we get

S₈₀ = 0.99 ( 1 - 0.99⁸⁰ ) ( 1 - 0.99 )

On further simplification , we get

S₈₀ = 0.7224

So , the sum of the GP is S = 1 - S₈₀ = 0.28

Hence , the sum of GP is 0.28

The scale for this drawing is 3 in. = 8 ft. On the drawing, the length of the kitchen measures 7 in. What is the length of the actual Kitchen? Round your

answer to the nearest foot.

Answers

Answer:

19 feet

Step-by-step explanation:

First we must make the scale make sense, that is, it is in the same unit, therefore, we will pass 3 inches to feet, we know 1 foot is 12 inches, therefore:

3 inches * 1 foot / 12 inches = 0.25 feet

Which means that the real equivalence is 0.25: 8, now they are 7 inches, therefore:

7 inches * 1 foot / 12 inches = 0.583333

Now, we calculate the number of actual feet using the scale.

0.583333 * 8 / 0.25 = 18.66 feet

that is to say that the length of the current Kitchen is 19 feet if we round

Sandy does babysitting in her spare time. She gets $100 advance pay and $10 per hour for babysitting. She wants to earn enough to buy a new Iphone for $450. How many hours she needs to babysit to earn enough money to buy the Iphone?

Answers

Answer: 35 hours

Step-by-step explanation: 450-100 because of the advanced pay, then you dived 350 by ten so you get 35 hours

Answer:

Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.

Explanation:

Sandy gets $100 advance pay and $10 per hour for babysitting.

Let x denotes the number of hours then  

10x + 100

Sandy wants to buy an Iphone for $450

10x + 100 = 450

Solving the above equation

10x = 450 - 100

10x = 350

x = 350/10

x = 35 hours

Therefore, Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.

Owners of a minor league baseball team believe that a Normal model is useful in projecting the number of fans who will attend home games. They use a mean of 8500 fans and a standard deviation of 1500 fans. Using this model, answer these questions. a. Sketch and clearly label this Normal model, based on the 68-95-99.7 Rule. b. What proportion of the home games will have fewer than 6000 fans in attendance

Answers

Answer:

a) [tex] \mu -\sigma = 8500 -1500 = 7000[/tex]

[tex] \mu +\sigma = 8500 +1500 =10000[/tex]

[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]

[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]

[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]

[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]

On the figure attached we have the illustration for required showing the percentages and the limits for each case

b) [tex] z= \frac{6000-8500}{1500}= -1.67[/tex]

And using the normal standard table or excel we got:

[tex] P(Z<-1.67) = 0.047[/tex]

Step-by-step explanation:

For this case we have the following properties:

[tex] \mu = 8500, \sigma = 1500[/tex]

Part a

And for this case from the empirical rule we know that within one deviation from the mean we have 68% of the values , within two deviation 95% and within 3 deviations 99.7%. So then we can find the limits like this:

[tex] \mu -\sigma = 8500 -1500 = 7000[/tex]

[tex] \mu +\sigma = 8500 +1500 =10000[/tex]

[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]

[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]

[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]

[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]

On the figure attached we have the illustration for required showing the percentages and the limits for each case

Part b

For this case we want to find this probability:

[tex] P(X<6000)[/tex]

We can calculate the number of deviation below the mean with the z score formula given by:

[tex] z = \frac{X -\mu}{\sigma}[/tex]

And replacing we got:

[tex] z= \frac{6000-8500}{1500}= -1.67[/tex]

And using the normal standard table or excel we got:

[tex] P(Z<-1.67) = 0.047[/tex]

Micah is filling up his cone-shaped cup with water. The cup (as shown) has a diameter of 72 millimeters and a slant height of 45 millimeters. How much water can Micah fill in his cup?

Answers

Answer:

Micah can put 61072.56 ml³ of water in his cup.

Step-by-step explanation:

The volume of a cone is given by the following formula:

[tex]V = \frac{h\pi r^{2}}{3}[/tex]

In which h is the height and r is the radius.

The radius is half the diameter.

In this question:

Radius of 72/2 = 36 ml. So [tex]r = 36[/tex]

Height of 45 ml, so [tex]h = 45[/tex]

The dimensions are in ml, so the volume will be in ml³.

So

[tex]V = \frac{h\pi r^{2}}{3}[/tex]

[tex]V = \frac{45\pi*(36)^{2}}{3}[/tex]

[tex]V = 61072.56[/tex]

Micah can put 61072.56 ml³ of water in his cup.

what is the sum of this arithmetic series? 586+564+542+...+212

Answers

Answer:

Basically it's asking for the sum of 212 + 216 + 220 + ..... 586

Each number is 22 more than the previous one.

Therefore the sum will be 212 + (212+22) + (212+22*2) + (212+22*3)

the amount of numbers from 212 through 586 is 18.

Therefore we will need 212 plus 212 * 17 = 3,816 *******************

We will also need all those 22's.

We must add 22 *1 plus 22*2 plus 22*3 ..... plus 22*17

Which equals 22 + 44 + 66 + 88 ... 374

Which totals 3,366 *****************

So, we total 3,816 + 3,366 which equals 7,182

Step-by-step explanation:

 

[tex]\displaystyle\bf\\Sum=586+564+542+...+212\\\\Sum=212+234+256+...+586\\\\\textbf{We calculate the number of terms (n):}\\\\n=\frac{586-212}{22}+1=\frac{374}{22}+1=17+1=18\\\\\boxed{\bf~n=18~terms}\\\\Sum=\frac{n(586+212)}{2}\\\\Sum=\frac{18\times 798}{2}\\\\Sum=9\times798\\\\\boxed{\bf~Sum=7182}[/tex]

s : d = 5 : 7

In other words:

s / d = 5 / 7

If there are 70 sailboats, this implies that s = 70

=> 70 / d = 5 / 7

=> d = (70 * 7) / 5 = 490 / 5 = 98

There will be 98 dinghies.
