P(x)equals=​R(x)minus−​C(x). Given ​R(x)equals=59 x minus 0.3 x squared59x−0.3x2 and Upper C left parenthesis x right parenthesi
Deffense [45]

Answer:

P(x)=-0.3x^2+56x-14  

Step-by-step explanation:

The given functions are

R(x)=59x-0.3x^2

C(x)=3x+14

It is given that

P(x)=R(x)-C(x)

Substitute the values of given functions in the above equation.

P(x)=59x-0.3x^2-(3x+14)

P(x)=59x-0.3x^2-3x-14

Combine like terms.

P(x)=-0.3x^2+(59x-3x)-14

P(x)=-0.3x^2+56x-14  

Therefore, the required function is P(x)=-0.3x^2+56x-14   .

Yolanda’s club require that 60% of the members be present for any vote. If at least 30 members must be present to have a vote ho
balandron [24]
We can rewrite this problem as:
What is 60% of 35?
"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as
60
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number of members we are looking for "m".
Putting this altogether we can write this equation and solve for
m
while keeping the equation balanced:
m
=
60
100
×
35
m
=
2100
100
m
=
21
21
members must be present to have a vote.

Dahasolnce [82]

Answer:

\large\boxed{\sqrt{300x^{15}}=10x^7\sqrt{3x}}

Step-by-step explanation:

Domain: x\geq0\\\\\sqrt{300x^{15}}=\sqrt{100\cdot3\cdot x^{14+1}}\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\sqrt{100\cdot3\cdot x^{14}\cdot x^1}\\\\\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt{100}\cdot\sqrt3\cdot\sqrt{x^{14}}\cdot\sqrt{x}=10\cdot\sqrt3\cdot\sqrt{x^{7\cdot2}}\cdot\sqrt{x}\\\\\text{use}\ (a^n)^m=a^{nm}\\\\=10\cdot\sqrt3\cdot\sqrt{(x^7)^2}\cdot\sqrt{x}\\\\\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\=10\cdot\sqrt3\cdot x^7\cdot\sqrt{x}=10x^7\sqrt{3x}
