Answer:
<h2>282.857 in²</h2>
Step-by-step explanation:
The formula of a surface area of a cylinder:
r - radius
H - height
We have:
r = 5 in
H = 4 in
Substitute:
Substitute:
Ok so Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of
16x^2-40x+25square inches.
Let y(x) =16x^2-40x+25
If differentiating both sides w.r.t x we get
y'(x)=32x-40
And
to find critical point x ,Put y'(x)=0 then
32x-40=0
x=5/4
It doesn’t show a picture
13/5 is the smaller number
Answer:
Exponential function is:
y = 100 (1.03)ˣ
Step-by-step explanation:
We know that the exponential growth function is of the form
y = a (1 + r)ˣ
Here:
a = initial value
r = growth rate
x = number of time intervals that have passed
Given that A new savings account is opened with 400. Thus,
a = 400
Given that a new saving account gains 3% every year.
r = 3% = 0.03
now substituting a = 400 and r = 0.03 in the function
y = a (1 + r)ˣ
y = 100 (1 + 0.03)ˣ
y = 100 (1.03)ˣ
Therefore, exponential function is:
y = 100 (1.03)ˣ
<em>Please note that the growth factor i.e. 1.03 is greater than 1, so the exponential function represents exponential growth.</em>
