30 POINTS AVAILABLE

Answer:

$\large\boxed{(x-2)^2+(y-1)^2=34}$

Step-by-step explanation:

The equation of a circle in standard form:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

We have the endpoints of the diameter: (-1, 6) and (5, -4).

Midpoint of diameter is a center of a circle.

The formula of a midpoint:

$\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

Substitute:

$h=\dfrac{-1+5}{2}=\dfrac{4}{2}=2\\\\k=\dfrac{6+(-4)}{2}=\dfrac{2}{2}=1$

The center is in (2, 1).

The radius length is equal to the distance between the center of the circle and the endpoint of the diameter.

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the points (2, 1) and (5, -4):

$r=\sqrt{(5-2)^2+(-4-1)^2}=\sqrt{3^2+(-5)^2}=\sqrt{9+25}=\sqrt{34}$

Finally we have:

$(x-2)^2+(y-1)^2=(\sqrt{34})^2$

Matt wants to buy a television. If he

VladimirAG [237]

Answer:

The cost of the television is $\$294$

Step-by-step explanation:

Let

x -----> the cost of the television in dollars

we know that

The cost of the television represent 100%

If Matt pays cash

then

$100\%-7\%=93\%=93/100=0.93$

The cost is 0.93x

If Matt pays with a loan

then

$100\%+10\%=110\%=110/100=1.1$

The cost is 1.1x

The difference between the two methods is

$1.1x-0.93x=0.17x$

Remember that

The difference between the two methods is $49.98

$0.17x=49.98$

Solve for x

$x=\$294$

olganol [36]

Answer:

x=-1

Step-by-step explanation:

-7 < 3(x) + 5 ≤ 7

-7 < 3(-1) + 5 ≤ 7

-7 < -3 + 5 ≤ 7

-7 < 2 ≤ 7
