Verify the identity. <br> Please show your work.
m_a_m_a [10]

Step-by-step explanation:

To prove :

( 1 - sin x ) ( 1 + sin x ) = sec² x

LHS : -

( 1 - sin x ) ( 1 + sin x )

Formula / Identity : -

( a - b ) ( a + b ) = a² - b²

Here,

a = 1

b = sin x

( 1 - sin x ) ( 1 + sin x )

= 1 - sin² x

Identify : -

sin² θ + cos² θ = 1

cos² θ = 1 - sin² θ

Similarly,

1 - sin² x

= cos² x

= RHS

Hence verified.

algerbra. com The ninth graders at a high school are raising money by selling T-shirts and baseball caps. The number of T-shirts
My name is Ann [436]

Answer:

36 T-shirts and 12 Baseball Caps

Step-by-step explanation:

GIVEN: The ninth graders at a high school are raising money by selling T-shirts and baseball caps. The number of T-shirts sold was three times the number of caps. The profit they received for each T-shirt sold was \$5.00, and the profit on each cap was \$2.50.

TO FIND: If the students made a total profit of \$210, how many T-shirts and how many caps were sold.

SOLUTION:

Let the total number of T-shirts sold are =\text{t}

Let the total number of Baseball Caps sold are =\text{b}

Profit received on each T-shirt =\$5.00

Profit received on each Baseball Caps =\$2.50

Total profit received on T-shirts =\$5.00\text{t}

Total profit received on Baseball Caps =\$2.50\text{b}

5\text{t}+2.5\text{b}=210

Also,

The number of T-shirts sold was three times the number of caps.

        \text{t}=3\text{b}

putting in equation,

       5\times\text{3b}+2.5\text{b}=210

       17.5\text{b}=210

       \text{b}=12

       \text{t}=3\times12

       \text{t}=36

Hence total 36 t-shirts and 12 baseball Caps were sold.

Jake has 1 yard of cloth. He makes bookmarks that are each 1 1/8 inches long. How many bookmarks can he make?
PolarNik [594]
<span>Jake has 1 yard of cloth. He makes bookmarks that are each 1 1/8 inches long.
Let’s find out how many bookmarks can he make.
Unit of conversion:
=> 1 yard = 36 inches.
Now, he divided it to 1 and 1/8 inches
=> 1 and 1/8 = 1.125 inches
So let’s divide this with 36 inches
=> 36 / 1.125 = 32
Thus jake can make a total of 32 bookmarks out of 1 yard of cloth with a measurement of 1 and 1/8 inches.
