Answer:

(x-4)² + (y+3)² = 9

Step-by-step explanation:

The equation of a circle of radius r centered at (h, k) is ...

... (x-h)² + (y-k)² = r²

Subsituting your given values gives ...

... (x -4)² +(y -(-3))² = 3²

... (x -4)² +(y +3)² = 9

For every positive even integer n, the function h(n) is defined to be the product of all the even integers from 2 to n, inclusiv
Ugo [173]

Answer:

More than 50

Step-by-step explanation:

To solve, we need to first see that the function is h(n). Picking main points from the question statement:

  • h(n) is the product of all even integers (From 2 to n)
  • p is the smallest factor of h(100)+1
  • h(100)+1 , here n=100

From here, we can write h(100) as:

h(100) = 2 * 4 * 6 * 8 * ...... * 100

h(100) = 2^{50} * (1*2*3*......*50)= 2^{50} * 50!

so,

h(100)+1 =(2^{50} * 50! )+1

Now two numbers,

h(100) and h(100)+1 are consecutive integers and since they are consecutive so they are co-prime. Hence they only have common factor of 1. Example, 13 and 14 have only common factor of 1

As h(100) has all prime numbers from 1 to 50 and according to above statement h(100)+1 won't have any prime factor from 1 to 50, so the smallest prime factor p is greater than 50.

Match each polynomial function with one of its factors.
insens350 [35]
Ex.
2 {x}^{4}  + 8 {x}^{3}  + 4 {x}^{2}  + 2 {x}^{2}
This would be

2 {x}^{2} ( {x }^{2}  + 4x)(2 + 1)

How?

Group them
(2 {x}^{4 }   + 8 {x}^{3} )(4 {x}^{2}  + 2 {x}^{2} )

Make sure there is a GCF.
2 {x}^{2} ( { x}^{2}  + 4x)(2 + 1)

Hope this was clear

Calculate the volume of a cone whose base radius is 3 and half cm and vertical height 24cm​
Firlakuza [10]

The volume of a cone whose radius is 3 1 / 2 cm and vertical height is 24 cm is 307.72 cm³

<h3>Volume of a cone</h3>

The volume of a cone can be represented as follows:

volume = 1 / 3 πr²h

where

  • r = radius
  • h = height

Therefore,

r  = 3 1 / 2 cm = 7 / 2 cm

h = 24 cm

Hence,

volume = 1 / 3 × π  × (7 / 2 )² × 24

volume of a cone = 1 / 3 × π × 49 / 4 × 24

volume of the cone = 1 / 3 × π × 1176 / 4

volume of the cone =  1176 / 12 π

volume of the cone = 98π

volume of the cone =  307.72 cm³

Annual salary plus bonus data for chief executive officers are presented in the BusinessWeek Annual Pay Survey. A preliminary sa
Anuta_ua [19.1K]

Answer:

175

Step-by-step explanation:

The sample size n in<em> Simple Random Sampling</em> is given by

\bf n=\frac{z^2s^2}{e^2}

<em> where z = 1.96 is the z-score associated with a 95% confidence level ans s the standard deviation. </em>

Replacing values

\bf n=\frac{(1.96)^2(675)^2}{(100)^2}=175

So, there should be 175 chief executive officers in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000
