A circle is represented by the equation below: (x + 8)2 + (y − 3)2 = 100 Which statement is true?

The circle is centered at (−8, 3) and has a radius of 20.

The circle is centered at (8, −3) and has a diameter of 20.

The circle is centered at (8, −3) and has a radius of 20.

The circle is centered at (−8, 3) and has a diameter of 20.

Answers

Answer:

D) The circle is centred at (-8,3) and has a diameter 20

Step-by-step explanation:

Explanation:-

Given that the circle

        ( x + 8)² +( y-3)² = 100

   ⇒ ( x + 8)² +( y-3)² = 10²

Standard form of the circle ( x-h)² +(y-k)² = r²

Centre of the circle (h , k) = (-8 , 3)

Radius of the circle  r = 10

Diameter of the circle 'd' = 2r = 2(10) =20

Final answer:-

The circle is centred at (-8,3) and has a diameter 20

Answer:

The circle is centered at (−8, 3) and has a diameter of 20.

What is the equation of a line that is perpendicular to a line with a slope of 2 and passes
through the point (-2, 0)?

Answers

To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3

Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.

y=3x+b

2=3*(3)+b

2=9+b

-7=b  So now we know the y-intercept and slope. We just put them together now

y=3x-7

The price of nails, n, is $1.29/lb. The price of washers, w, is $0.79/lb. The price of bolts, b, is $2.39/lb.

Section a .Write an expression to represent the total price of the supplies

Section b. What is the total cost of buying 2 pounds of nails, 4 pounds of washers and 3 pounds of bolts?

Answers

Answer: 1.29n + 0.79w + 3.39b  is the expression.

The total cost is $12.91

Step-by-step explanation:  Substitute the number of pounds for each given supply. Multiply to get the individual amounts, then add all of those amounts to find the total cost.

1.29(2) + 0.79(4) + 2.39(3) = total

2.58 + 3.16 + 7.17 = 12.91

Answer:

1.29n + 0.79w + 2.39b

1.29(2) + 0.79(4) + 2.39(3) =

2.58 + 3.16 + 7.17 = $12.91

The house was bought for $125,000 in 1990, the overage rate is 7.85%, what year will the purchase of the house be worth 3 times the purchase price?

Answers

Answer: 2005

Step-by-step explanation:

Exponential function to determine the value of item after t years,

[tex]f(x)=A(1+r)^t[/tex] , where r= rate of growth, A=Initial value.

As per given , A = 7.85% = 0.0785

A = $125,000

Substitute all values in function, we get

[tex]f(x)=125000(1+0.785)^t[/tex]

When f(x)= 3A , then

[tex]3A=A(1.0785)^t\\\\\Rightarrow\ 3=(1.0785)^t[/tex]

Taking tog on both sides , we get

[tex]\ln 3=t\ln 1.0785\\\\\Rightarrow\ t=\dfrac{\ln 3}{\ln 1.0785}\\\\\Rightarrow t=\dfrac{1.09861228867}{0.0755711868471}\approx15[/tex]

The year will be 1990+15= 2005

Hence, the required year = 2005

Answers

Answer: D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}

Step-by-step explanation:

A relation R is said to be a function if for each input value there exists only one unique output value.

In (x,y)  , x= Input value , y= output value.

A. {(-1, - 4), (-1,0), (- 1,5), (- 1, 7), (-1,9)}

Here, -1 has two output values -4 and 0.

So it is not a function.

B. (-2, - 4), (-1,7), (1, - 1), (1, 1), (3,9)}

Here, 1 has two output values -1 and 1.

So it is not a function.

C. {(-4,9), (- 3, 1), (- 2, 3), (- 2, 12), (0, 6) }

Here, -2 has two output values 3 and 12.

So it is not a function.

D. {(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)}

here, each input value has an unique output value.

Hence, D. option is correct.
