PLEASE HELP ME ASAP WILL MARK BARINLIEST

Mathematics
1 answer:
Lesechka [4]3 years ago

Answer:

Yes, she is Correct

Step-by-step explanation:

I could prove this through writing the exponential equation that resembles this equation, but it's simpler than that:

It mentions that the population would be half of what it was before (a decade before). Now it is safe to say that every exponential (not decaying) equation gradually increases so that every value differs from it's consecutive value through multiplication of a constant.

<em>That is why, given the population would be half of what it was before, 0.5 acts as the 'constant' and the word problem can be modeled by an exponential graph + exponential function.</em>

A cylindrical container has a radius of 3 centimeters and a height of 12 centimeters. The container is filled with water up to t
evablogger [386]

Answer:

volume of empty space = 141.3 cm³

Step-by-step explanation:

volume of empty space = volume of the cylinder - volume of water

First, we need to calculate the volume of the container

volume of a cylinder = πr²h

 where r = radius of the container   and   h is the height of the container

r = 3cm  and h = 12 cm    π is a constant which is ≈ 3.14

volume of a cylinder = πr²h

                                  =3.14 × 3²×12

                                   =3.14×9×12

                                    =339.12 cm³

We will proceed to find the volume of water

since liquid will take the shape of its container,

then volume of water =  πr²h

r is the radius of the container   and    h is the height of the water

r = 3cm    and   h = 7cm      

volume of water =  πr²h

                             = 3.14 ×3²×7

                              =3.14×9×7

                              =197.82 cm³

volume of empty space = volume of the cylinder - volume of water

                                          =339.12 cm³    -    197.82 cm³

                                          = 141.3 cm³

OR

WE CAN SOLVE DIRECTLY

height of empty space = height of container - height of water

                                       = 12 - 7

                                        =5 cm

volume of empty space = πr²h

                                        =3.14×3²×5

                                        =3.14×9×5

                                         =141.3 cm³

volume of empty space = 141.3 cm³

Which function has the greatest rate of exponential growth?
Veronika [31]

Answer:

C

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value

wariber [46]

Answer:

According to most financial experts, it's wise to save at least six months of net living expenses in an emergency fund. So if a family requires $3,000 a month to pay all of its expenses, then it should strive to accumulate $18,000 in an interest bearing emergency savings account.
