Write the range of the function given in the graph in interval notation.However, it is much better to write it in set notation or interval notation. Here's the summary of the domain and range of the given function written in two ways… Because the function involved is a line, I can predict that the range is all y values . It can definitely go as high or as low without any limits.

d. (-4,3)∪(3,8)

Find S11 for 1 + 2 + 4 + 8 +

Free_Kalibri [48]

Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,

Sn = a1 x (1 - r^n) / (1 - r)

where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,

 Sn = 1 x (1 - 2^11) / (1 - 2) = 2047

Thus, S11 is 2047.

The level of water in a dam was decreasing by 20% each day. If the level of water was 1500cm,what was the level after two days?

makkiz [27]

Answer:

$L_o= 1500 cm$

And we know that the level is decreasing 20% each day so then we can use the following model for the problem

$L_f = L_o (1-0.2)^t$

Where t represent the number of days and L the level for this case we want to fnd the level after two days so then t =2 and replacing we got:

$L_f = 1500cm(0.8)^2 = 960cm$

Step-by-step explanation:

For this case we know that the initial volume of water is:

$L_o= 1500 cm$

And we know that the level is decreasing 20% each day so then we can use the following model for the problem

$L_f = L_o (1-0.2)^t$

Where t represent the number of days and L the level for this case we want to fnd the level after two days so then t =2 and replacing we got:

$L_f = 1500cm(0.8)^2 = 960cm$

yKpoI14uk [10]

One third is the written form.
Also, just a bit of extra information! The decimal of 1/3 is 0.33(recurring)

An object travels 4/5 mile in a half in hour. What is its speed?

goldfiish [28.3K]

The rate(speed) is 1 3/5

We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr

Substitute

4/5= 1/2t

Multiply 2 on both sides
2* (4/5)=(1/2)t * 2

8/5=t

We can simplify this to 1 3/5
