When x = 1
5(1) = -y + 6
5 = -y + 6
y = 6 - 5 = 1

When x = 2
5(2) = -y + 6
10 = -y + 6
y = 6 - 10 = -4

When x = 3
5(3) = -y + 6
15 = -y + 6
y = 6 - 15 = -9

Test 1 in for x

5(1)= -y +6
5= -y+6
Subtract 6 from both sides

-1 = -y

Divide by -1 to get 1=y

x=2
5(2)= -y +6
10= -y+6

Subtract 6 from both sides
4= -y

Divide by -1

-4=y
---------------------------
X=3
5(3)= -y +6
15= -y +6

Subtract 6 from both sides
9= -y

Divide by -1
-9 = y

Find the circumference and area of a circle with a diameter of 22 inches.

Katyanochek1 [597]

Answer:

$Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2$

Step-by-step explanation:

Diameter of the circle= $22\;inches$

$Radius=\dfrac{22}{2} =11\;inches$

Circumference of a circle:

$=2\times \pi \times r$

$=2\times \pi \times 11\\\\=22\pi \;inches$

Area of the circle:

$=\pi \times r^2$

$=\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2$

INTELLIGENT STUDENT IN TRIG?.Ill give brainlest

Answers:

x = 6

y = 6*sqrt(2)

=======================

Explanation:

To find these values, you can use the general template of a 45-45-90 triangle or you can use trig ratios

tan(45) = 1

tan(angle) = opposite/adjacent

tan(45) = x/6

1 = x/6

6*1 = x

x = 6

-------

sin(45) = 1/sqrt(2)

sin(angle) = opposite/hypotenuse

sin(45) = 6/y

1/sqrt(2) = 6/y

1*y = sqrt(2)*6

y = 6*sqrt(2)
