Answer:

The equation of the line is y = 7/2x + 8

Step-by-step explanation:

The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept.  To find m, you just have to subtract the two points from each other.

\frac{8 - 1}{0 - (-2)}   = 7/2

The y - intercept always has an x-value of 0, so the y-intercept would be 8.

So, the equation is y = 7/2x + 8

The Perimeter or a regular pentagon is 41.5cm. Write and solve an equation to determine the length of each side of the pentagon
olchik [2.2K]

Answer:

8.3 cm

Step-by-step explanation:

So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.

Perimeter (P) = s+s+s+s+s (sides)

P: 41.5 cm ÷ 5 =

8.3 cm

We know this is correct because:

8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5

Hope this helps!

For problems 1, 2, and 3, use the function g(x) = sin(6x) .
Fantom [35]

Step-by-step explanation:

1. Amplitude = 1.  g(x) = 1 sin(6x).  The coefficient 1 is the amplitude.  The range of the function is -1 \le g(x) \le 1  or, in interval notation, [-1, 1]

2. The period is  \frac{2\pi}{6}=\frac{\pi}{3}.

x-intercepts (at the beginning, middle, and end of the period) 0,\,\frac{\pi}{6},\,\frac{\pi}{3}

Maximum (1/4 of way through period)  \left(\frac{\pi}{12},\,1 \right)

Minimum (3/4 of way through period)  \left( \frac{\pi}{4}, \, -1 \right)

-10r,20r-30r,40r next term in the sequence?
Dima020 [189]
-50r would be the next term because a simpler way to look at it is every other term it is switching from negative to positive.
