Answer:

Step-by-step explanation:

hello :

p(x) = 5(x + 3)2 – 45

the vertex is the point : A(-3 ; -45)

minimum -45

the axis of symmetry  is the line when an equation is : x =  -3

PLEASE HELP!! I will give BRAINLIEST!! What is the range of possible sizes for side x?
Novay_Z [31]

Answer:

.5 < x < 16.5

Step-by-step explanation:

The smallest x  can be is greater than the difference of the other two sides

8.5 -8 = .5

The largest x can be the less than the sum of the two sides

8.5+8 = 16.5

.5 < x < 16.5

An equation was used to predict possible sales of phones for 6 months. The actual sales of phones are also listed.Actual sales 5
Vikki [24]

Answer:

20

Step-by-step explanation:

To calculate the sum of the residuals, subtract the predicted sales from the actual sales in the table below.

Actual sales 55 150 325 510 780 990

Predicted sales 40 150 300 500 800 1,000

This will show the change between them. Add each residual to find the sum.

55 - 40 = 15

150 - 150 = 0

325 - 300 = 25

510 - 500 = 10

780 - 800 = -20

990 - 1000 = -10

These add up to be 15 + 25+ 10 +-20 +-10  = 20

A window is in the form of a rectangle capped by a semicircle. The width of the rectangular portion is equal to the diameter of
xxTIMURxx [149]

Answer:

The answer is below

Step-by-step explanation:

Let x be the diameter of the semicircle. radius = x/2

The window is a combination of a rectangle and semicircle.

Width of window = diameter = x, let length of the window = y.

Perimeter of semicircle = πr = πx/2

Perimeter of window = x + y + y + πx/2

20 = x + 2y + πx/2

2y + x + πx/2 = 20

2y = 20 - x(1 - π/2)

y = 10 - x(1 - π/2)/2

Area of semicircle = (1/2)πr² = (1/2)π(x/2)²

Area of window = xy + (1/2)π(x/2)²

A = x(10 - x(1 - π/2)/2) + πx²/8

A = 10x - x² - πx²/4 + πx²/8

A = 10x - x² - πx²/8

The maximum area is at dA / dx = 0

dA / dx = 10 - 2x - 2πx/8

0 = 10 - 2x - πx / 4

2x + πx / 4 = 10

2.785x = 10

x = 3.59 feet

Maximum area = 10x - x² - πx²/8 = 10(3.59) - 3.59² - π(3.59²) / 8

Maximum area = 17.95 feet²
