GarryVolchara [31]

Answer:

The height of the tree is 30 feet

Step-by-step explanation:

Let

h ----> the height of the tree

we know that

The tree casts a shadow that is 27 feet long

Your friend is 5 feet tall and casts a shadow that is 4.5 feet long

so

using proportion

Find out the height of the tree

\frac{h}{27}=\frac{5}{4.5}\\\\h=27(5)/4.5\\\\h=30\ ft

Explain why the sum of two rational numbers is always rational. To earn full credit, you must provide an expression or example A
scoundrel [369]
So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.


a/b and c/d are rational numbers with a,b,c,d intergers

so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of

same denominator= b is not equal to 0
different denominators= d is not equal to 0



this may not make sense but i'm pretty sure i understood you right

If f(x)=(e^(2x)+1)^1/2 then f'(0)=
Kryger [21]
We will first find f ` ( x ) using the chain rule:
f ` ( x ) = \frac{1}{2 \sqrt{e ^{2x}+1 } } * 2e^{2x} =  \frac{e^{2x} }{ \sqrt{e ^{2x} +1} }
f ` ( 0 ) = \frac{e ^{0} }{ \sqrt{e^{0}+1 } } = \frac{1}{ \sqrt{2} }
Answer: f ` ( 0 ) = 1/√2    ( or: √2/2 )
