Select the correct answer. Which point lies on a circle with a radius of 5 units and center at P(6, 1)? A. Q(1, 11) B. R(2, 4) C

jasenka [17]

Answer:

T(9,-2)

Step-by-step explanation:

The circle has radius 5 units and center P(6,1).

The equation of this circle is

$(x-6)^2+(y-1)^2=5^2$

$(x-6)^2+(y-1)^2=25$

If Q(1,11) lies on this circle, then it must satisfy its equation.

$(1-6)^2+(11-1)^2=25$

$(-5)^2+(10)^2=25$

$25+100=25$ , this statement is false.

If R(2,4) lies on this circle, then it must satisfy its equation.

$(2-6)^2+(4-1)^2=25$

$(-4)^2+(3)^2=25$

$16+9=25$ , this statement is false.

If S(4,-4) lies on this circle, then it must satisfy its equation.

$(4-6)^2+(-4-1)^2=25$

$(-2)^2+(-5)^2=25$

$4+25=25$ , this statement is false.

If T(9,-2) lies on this circle, then it must satisfy its equation.

$(9-6)^2+(-2-1)^2=25$

$(4)^2+(-3)^2=25$

$16+9=25$ , this statement is TRUE.

The correct answer is D

The cost of a compact disc is $18. Mrs. Meridth bought 3 discs and received a 15% discount. If the sales tax is 8.8%, find the t

Harlamova29_29 [7]

Answer:

$49.572

Step-by-step explanation:

Given that :

Cost per disc = $18

Number of disc purchased = 3

Discount received = 15%

Sales tax = 8%

Original cost : cost per dic * number purchased

Original cost = $18 * 3 = $54

Discounted price = (100 - 15)% * $54

Discounted price = $45.9

Sales tax :

(100 + 8)% of $45.9

108% * $45.9

= $49.572

Total price = $49.572

F(x) 3x^2+x-3 g(x)=x^2-5x+1 find f(x)-g(x)

wel

Answer:

2x² + 6x - 4

Step-by-step explanation:

f(x) - g(x)

= 3x² + x - 3 - (x² - 5x + 1) ← distribute

= 3x² + x - 3 - x² + 5x - 1 ← collect like terms

= 2x² + 6x - 4

A and B share the cost in a ratio of 3:2 A pays 125£ how much does b pay???

lana66690 [7]

Let the common multiple be x
3x : 2x 
3x = 125 
x = 125/3 

So, B pays 2x = 2 × 125/3 = £250/3
