1. intersect at x=45

so y=sqrt(2)

2. y=cscx period is doubled y=tanx

3. not the same

4. no local maximum of y=secx

minimum point of y=sinx is -1

9,-81, 729,-6561...<br> What is the common ratio?<br> Help which is the correct answer?

GrogVix [38]

Answer:

$r = -9$

Step-by-step explanation:

Given

$Sequence: 9,-81, 729,-6561...$

Required

Determine the common ratio

The common ratio r is calculated using:

$r = \frac{T_n}{T_{n-1}}$

Let $n = 2$

So, we have:

$r = \frac{T_2}{T_{2-1}}$

$r = \frac{T_2}{T_1}$

From the sequence:

$T_2 = -81$

$T_1=9$

So, the equation becomes

$r = \frac{-81}{9}$

$r = -9$

D'Quan grandmother made a quilt for his bed. The quilt is 2.44 meters long and 1.83 meters wide. What is the are of the quilt in

Artemon [7]

Answer:

48.063 square feet.

Step-by-step explanation:

We have been given that D'Quan grandmother made a quilt for his bed. The quilt is 2.44 meters long and 1.83 meters wide.

We can see that quilt is in form of a rectangle and area of a rectangle equals to width times length.

$\text{Area of rectangle}=\text{length}*\text{Width}$

Upon substituting our given values in above formula we will get,

$\text{Area of quilt}=2.44\text{ meters}*1.83\text{meters}$

$\text{Area of quilt}=4.4652\text{meters}^{2}$

1 square meter= 10.7639 square feet.

Now let us convert our given area in square feet by multiplying 4.4652 by 10.7639.

$\text{Area of quilt}=4.4652*10.7639$

$\text{Area of quilt}=48.06296628\approx 48.063$

Therefore, the area of quilt 48.063 square feet.

marin [14]

Let’s work out how much they would be paid in one day:
6000/5 = 1200 for six people in one day.

Now to find 12 days, just times 1200 by 12:
1200*12 = 14400 for six people in 12 days.

Now to find the difference:
14400-6000 = 8400 is how much more money they could’ve made

Answer: 8400
