Answer:
20 <h<30
Step-by-step explanation:
There are 30 plants so the medians is 30/2 = 15, between the 15 and 16 items
15 and 16th items are in the range 20 to 30, so the median is between 20 to 30
20 <h<30
This is a really interesting question!! exponential functions and logarithmic functions are actually inverses functions; the way to "undo" logarithms is by exponents, the way to "undo" exponents is by logarithms. an exponent tells you how many times you need to multiply a value; logarithms ask what exponent you need to get a certain value. you could use logarithms and exponents to calculate interest rates, as a real life example. they can also be used in calculating population growth or the half-life of an organism in biology.
(I) ||u+v||^2 = <u>

= <u>
= ||u||^2 + ||v||^2
(Ii) use what we proved in the first and should be trivial</u></u></u></u>
The answer is 6.4 x 8 in.
The scale 5 : 4 means that the old photo is 5 and the new photo is 4.
Now, let's find the new dimensions using the proportion for each side separately.
5 : 4 = 8 : x
x = 4 * 8 : 5
x = 6.4 in
_____
5 : 4 = 10 : y
y = 4 * 10 : 5
y = 8 in
