(1+sin y)(1+sin (-y))=cos^2 y)

Sloan [31]

$(1+siny)(1+sin(-y))=cos^2y\\\\L=(1+siny)(1-siny)=1^2-sin^2y=1-sin^2y=cos^2y\\\\R=cos^2y\\\\L=R$

$sin(-x)=-sinx\\\\sin^2x+cos^2x=1\to1-sin^2x=cos^2x\\\\(a+b)(a-b)=a^2-b^2$

Otis plans to make 3 batches of sidewalk chalk How much plaster of paris does he need

den301095 [7]

Answer:

$4\frac{1}{2}$ cups plaster of paris.

Step-by-step explanation:

Given:

for one batch of sidewalk chalk = $1\frac{1}{2}$ cup plaster of paris.

Number of bathes = 3

We need to find quantity of plaster of paris.

Solution:

For making 1 batch of sidewalk chalk = $1\frac{1}{2}$ cup plaster of paris.

For making 3 batches of sidewalk chalk = $3\times 1\frac{1}{2}$ cup plaster of paris.

$= 3\times \frac{2\times 1+1}{2}$

$= 3\times \frac{2+1}{2}$

$= 3\times \frac{3}{2}$

$= \frac{3\times 3}{2}$

$= \frac{9}{2}$

$=4\frac{1}{2}$

Therefore, he needed $4\frac{1}{2}$ cups plaster of paris.
