Answer:
The answer is A
Step-by-step explanation:
If there are 2.2 in 1 kilogram and you are trying to find out how many are in many kilograms then you multiply.
Hopefully this helps you :)
pls mark brainlest ;)
A can of paint is a cylinder, so we must use the surface area for a cylinder.
2(
r
) is the top and bottom.
The surface of the can is a rectangle with a length equal to the circumference of the can.
Step-by-step explanation:
a)
<u>The first laptop</u>
- Initial value- $2000
- Value loss - 14% every year
- Function for value- V(t) = 2000*0.86^t
<u>The second laptop</u>
- Initial value- $1200
- Value loss - 11% every year
- Function- V(t) = 1200*0.89^t
b)
Monthly percent decrease
<u>The first laptop:</u>
<u>The second laptop:</u>
c)
The second laptop will lose less value in 5 years hence is better choice

Answer:
3.25
Step-by-step explanation:
it is shrinking by a factor of 4 so every number is 4 times smaller and 13 divided by 4 will give you 3.25
Answer: The correct option is f(x) has three real roots and two imaginary roots.
Explanation:
It is given that the roots of fifth degree polynomial function are -2, 2 and 4+i.
Since he degree of f(x) is 5, therefore there are 5 roots of the function either real or imaginary.
According to the complex conjugate root theorem, if a+ib is a root of a polynomial function f(x), then a-ib is also a root of the polynomial f(x).
Since 4+i is a root of f(x), so by complex conjugate rot theorem 4-i is also a root of f(x).
From the the given data the number of real roots is 2 and the number of 2. The number of complex roots is always an even number, so the last root must be a real number.
Therefore, the correct option is f(x) has three real roots and two imaginary roots.
