You are expected to memorize the general shape of the sine function, including where the peaks and zero crossings are. The graph shows you the value of
sin(270°) = -1

The coordinates of a point on a coordinate grid are (−2, 6). The point is reflected across the x-axis to obtain a new point. The

Kipish [7]

So when you reflect the x-axis, you change the y negative. So (x,y) would be (x,-y). so it would be (-2, -6). If you want to reflect over the y-axis, it would be (-x, y).

James measured a piece of construction paper to be 6 3/4 inches wide and 9 2/3 inches long. What is the area of the piece of con

ivolga24 [154]

Answer:

The area of the piece of construction paper is $\frac{261}{4} inches^2$

Step-by-step explanation:

Length of construction paper = $6 \frac{3}{4} inches$

= $\frac{27}{4} inches$

Width of construction paper = $9 \frac{2}{3} inches$

= $\frac{29}{3} inches$

Area of construction paper = $Length \times Width$

Area of construction paper = $\frac{27}{4} \times \frac{29}{3}$

= $\frac{261}{4} inches^2$

Hence the area of the piece of construction paper is $\frac{261}{4} inches^2$

I solved it myself and my result is (n+1)/n. Why is that 1/2 there? An explanation would be great if possible. Thanks!

Answer:

The product of (k + 1) series starts with 3 (because k = 2) and you need 2 to be multiplied to this in order to get (n + 1)!

Therefore you need to multiply 2 and 1/2 to make it right. 2 completes the factorial and 1/2 remains.

Hope it was clear explanation.
