Answer:

Quadrant II

Step-by-step explanation:

The key piece of information besides the tangent information is that the sine is positive. That happens in quad 2 and quad 1.

Then tan is positive in quads 1 and 3. So the answer is not quad III.

Tan(theta) is minus in 2 and 4. So where does the intersection occur? The sine is plus in quad 2 and the tan is minus in quad 2. That's your answer.

Abc bookstore sells new books, n, for $12, used books, u, for $8, and magazines, m, for $5 each. The store earned $340 revenue l

poizon [28]

Answer:

The number of new books sold = 10

The number of used books sold (u) = 15

The number of magazines sold (m) = 20

Step-by-step explanation:

Let us assume the number of new books = n

So, the number of used books sold (u) = New books sold + 5 = n + 5

Also, the number of magazines sold (m) = 2 x ( Number of new books sold)

= 2 n

⇒ u = n + 5, m = 2 n

Here, the cost of each new book n- = $12

So, the cost of n new books = n x ($12) = 12 n

the cost of each used book u = $8

So, the cost of u = (n+ 5) used books = n+5 x ($8) = 8 n + 40

the cost of each magazine m = $5

So, the cost of m = (2n ) magazines = 2n x ($5) = 10 n

Also, total earnings = $340

⇒ 12 n + 8n +40 + 10 n = 340

or, 30 n = 300

or,n = 300/30 = 10

Hence the number of new books sold = n = 10

The number of used books sold (u) = n + 5 = 15

The number of magazines sold = m = 2 n = 20

What is another strategy that you can use to multiply 2 digit by 2 digit numbers?

ipn [44]

You may write them separating the units and tens digits, and then use FOIL to add 4 easy tems. For example, let's compute $21\cdot 36$ :

$21\cdot 36=(20+1)(30+6)=600+120+30+6 = 756$

At the end of April, Mandy told Bill that she has read 16 books this year and reads 2 books each month. Bill wants to catch up t

Dovator [93]

we know that

In an Arithmetic Sequence the difference between one term and the next is a constant

$an=a1+d*(n-1)$

where

a1 is the first term

d is the common difference between terms

n is the number of months (in this problem)

case a) Mandy

$a1=16 books$

$d=2$

$an=16+2*(n-1)$ ------> equation $1$

in this equation the first month is April

case b) Bill

$a1=4 books$

$d=4$

$an=4+4*(n-1)$ -------> equation $2$

In this equation the first month is May

With the equation $1$ and the equation $2$

calculate the attached table

therefore

the answer is

December
