Answer:

$x^{2} - 2x + y^{2} - 8y = 8$

Step-by-step explanation:

Standard form for a circle is:

$(x - h)^{2} + (y - k)^{2} = r^{2}$ (h, k) is the center r is the radius

$(x - 1)^{2} + (y - 4)^{2} = 5^{2} \\x^{2} - 2x + 1 +y^{2} - 8y + 16 = 25\\x^{2} - 2x + y^{2} - 8y = 8$ $x^{2} - 2x + y^{2} - 8y = 8$

Answer:

Step-by-step explanation:

The y-intercept is when x=0.

In this equation, that would mean T(0)=12(1.12)^0=12(1)=12.

The formula a=46c gives the floor area (a) in square meters that can be wired using (c) circuits

antoniya [11.8K]

a = 46c....for c
a/46 = c

322 = 46c
322/46 = c
7 = c.....7 circuits are required

Find the area of a trapezoid with a base of 21.6 m, a height of 4.5 m, and top of 11.9 m. Round your answer to the nearest hundr

Serga [27]

Answer:

$A=75.37\ m^2$

Step-by-step explanation:

Given that,

The base of a trapezoid, b = 21.6 m

Height of the trapezoid, h = 4.5 m

The tope of the trapezoid, a = 11.9 m

We need to find the area of a trapezoid. The formula for the area of a trapezoid can be given by :

$A=\dfrac{1}{2}\times (sum\ of\ parallel\ sides)\times height$

Put all the values,

$A=\dfrac{1}{2}\times (21.6+11.9)\times 4.5\\\\=75.37\ m^2$

Hence, the area of a trapezoid is equal to $75.37\ m^2$ .
