The answer is 15. you add up all the numbers, and divide it by 5 because thats how many numbers there are. Pretty basic ;)

You just have to add all the number together and divide it by the amount of the number so it would equal 15

ANSWER AND SHOW WORK FOR 40 POINTS

Elanso [62]

Answer:

Q1) (x+7)² = 9

x = -10, -4

Q2) (x-8)² = 144

x = -4, 20

Q3) (x-1)² = 81

x = -8, 10

Step-by-step explanation:

Q1) x² + 14x + 49 = 9

x² + 2(x)(7) + 7² = 9

(x + 7)² = 9

x + 7 = +/- sqrt(9)

x + 7 = 3

x = -4

x + 7 = -3

x = -10

Q2) x² - 16x + 64 = 144

x² - 2(x)(8) + 8² = 144

(x - 8)² = 144

x - 8 = +/- sqrt(144)

x - 8 = 12

x = 20

x - 8 = -12

x = -4

Q3) x² - 2x + 1 = 81

x² - 2(x)(1) + 1² = 81

(x - 1)² = 81

x - 1 =+/- sqrt(81)

x - 1 = 9

x = 10

x - 1 = -9

x = -8

GaryK [48]

Answer:

A multiple regression equation for this model can be expressed as:

$y=b_0+b_1x_1+b_2x_2+b_3x_3$

Step-by-step explanation:

To model this problem as a multiple regression equation, we need to define which are the independent and dependent variables.

The dependent variable is the one which we want to predict for any set of independent variables values. This is the case of the driver's automotive insurance monthly premiums.

The driver's automotive insurance monthly premiums is the dependent variable "y".

The independent variables are the ones that explain the dependent variable variation. In this case there are: number of miles driven per week (x1); the age of the car, in years (x2); and the number of accidents in which the driver has been involved in the past 5 years (x3).

Then, a multiple regression equation for this model can be expressed as:

$y=b_0+b_1x_1+b_2x_2+b_3x_3$

Consider parent function f(x)=e^x and the transformes function g(x)= -1/2e^3x+4, quantitatively explain the transformations to t

kolezko [41]

Answer: reflection across the x-axis

vertical shrink by a factor of 1/2

horizontal shrink by a factor of 1/3

vertical shift up 4 units

<u>Step-by-step explanation:</u>

$\text{Note:}\ g(x) = -Ae^{Bx-C}+D\\\bullet \quad \text{- represents a reflection across the x-axis}\\\\\bullet \quad \text{A represent a vertical stretch by a factor of A (shrink if}\ |A| < 1)\\\\\bullet \quad \text{B represents a horizontal stretch by a factor of}\ \dfrac{1}{B}\ (\text{shrink if}\ |B| >1) \\\\\bullet \quad \text{C represents a horizontal shift of C units}\ (\text{+ is right, - is left}) \\\\\bullet \quad \text{D represents a vertical shift of D units}\ (\text{+ is up, - is down})$

$\text{Parent function:}\ f(x)=e^x\\\text{Transformed function:}\ g(x)=-\dfrac{1}{2}e^{3x}+4\\$

The transformed function has the following:

Negative: reflection across the x-axis

A = 1/2 vertical shrink by a factor of 1/2

B = 3 horizontal shrink by a factor of 1/3

C = 0 no horizontal shift

D = 4 vertical shift of 4 units up
