Zolol [24]2 years ago

Answer:

Step by step

Step-by-step explanation:

Since we have the endpoints of the diameter, the midpoint coordinates of the line segment joining them gives the centre of the circle.

That is, centre (a,b) = ( [1+(-3)]/2, [4+2]/2) = (-1,3)

Distance between the given points give the diameter and half of that is the radius length.

So, radius r = (1/2)* sqrt ( [1-(-3)]^2 + [4–2]^2) = sqrt(5)

Thus equation required is: (x-a)^2 + (y-b)^2 = r^2

So, (x+1)^2 + (y-3)^2 = 5

Ostrovityanka [42]

Answer:

RM3,500

Step-by-step explanation:

Salary=RM375 per week

5% commission per week

If she target a minimum of RM 550.

Let x=minimum Sales

RM550=RM375 + 5% of x

RM550=RM375 + 0.05x

RM550 - RM375=0.05x

RM175=0.05x

Divide both sides by 0.05

RM175/0.05=0.05x/0.05

RM3,500=x

For Azila to earn a minimum of RM550 in a week, her salary will be RM375 plus 5% commission on the sales of RM3,500 value of product.

Check:

5% of RM3,500

=0.05*3,500

=RM175

Plus

Salary of RM375

RM175 + RM375=RM550

(-5, 0) and (-1, 0) are the solutions of -2(-x - 3)² + 8 = 0

Step-by-step explanation:

  • Step 1: Find the solutions of -2(-x - 3)² + 8 = 0.

Solutions are the intersecting points of y = -2(-x - 3)² + 8 and y = 0.

⇒ Solutions are (-5, 0) and (-1, 0)

  • Step 2: (-5, 0) and (-1, 0) are solutions of -2(-x - 3)² + 8 = 0

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
