Answer:

(1/2, 1)

Step-by-step explanation:

x² + y² − x − 2y − 11/4 = 0

x² − x + y² − 2y = 11/4

Complete the squares.

x² − x + 1/4 + y² − 2y + 1 = 11/4 + 1/4 + 1

(x − 1/2)² + (y − 1)² = 4

The center of the circle is (1/2, 1) and the radius of the circle is 2.

Algebra 1 9th grade<br>-2x=-18/3

cupoosta [38]

You would just decide both sides by 2.

-x = -9/3 ⇨ -3
Since both numbers are negative, the product becomes a positive.
x=3

Hope this helped!

99 POINT QUESTION, AND BRAINLIEST!!!

77julia77 [94]

$\displaystyle\int_{x=1}^{x=14}\frac{1-\cos4x}{4x-\sin4x}\,\mathrm dx$

First, replace $y=4x$ and $\mathrm du=4\,\mathrm dx$ . Then you have

$\displaystyle\frac14\int_{y=4}^{y=56}\frac{1-\cos y}{y-\sin y}\,\mathrm dy$

If we take $z=y-\sin y$ , then immediately we see a differential in the numerator in the form of $\mathrm dz=(1-\cos y)\,\mathrm dy$ . So the integral becomes

$\displaystyle\frac14\int_{z=4-\sin4}^{z=56-\sin56}\frac{\mathrm dz}z$

and evaluates to

$\dfrac14\ln|z|\bigg|_{z=4-\sin4}^{z=56-\sin56}=\dfrac14\left(\ln|56-\sin56|-\ln|4-\sin4|\right)=\dfrac14\ln\left|\dfrac{56-\sin56}{4-\sin4}\right|$

making (A) the correct answer.

The temperature is 78 °F at 2:00 in the afternoon. If the temperature drops 4 °F every hour after that, what is the temperature

Galina-37 [17]

Answer:

The answer to your question is: 54°F

Step-by-step explanation:

Data

Ti = 78°F

Initial hour = 2:00

Temperature drops 4°F every hour

Temperature at 8:00 = ?

Process

2:00

3:00 78-4 = 74°F

4:00 74-4 = 70°F

5:00 70-4 = 66°F

6:00 66-4 = 62°F

7:00 62-4 = 58°F

8:00 58-4 = 54°F
