Answer: Our required interval for temperature is 
Step-by-step explanation:
Since we have given that
The normal temperature range for Yuma, on Janurary is atleast = 48 degrees
and the highest temperature on that day is no higher than 64 degrees.
Let the temperature in Yuma be 'x'.
So, we know that for atleast means it can 48 degrees or more, and no higher than means it should be equa to or less than 64 degrees.
Mathematically, it is expressed as
Hence, our required interval for temperature is
A = $756.00
(I = A - P = $56.00)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Solving our equation:
A = 700(1 + (0.04 × 2)) = 756
A = $756.00
The total amount accrued, principal plus interest, from simple interest on a principal of $700.00 at a rate of 4% per year for 2 years is $756.00.
Answer:
7.5 miles
Step-by-step explanation:
Since she runs 5 miles in 38 minutes, she runs 
miles in one minute.
Hence, in 57 minutes she runs:
$ \frac{5}{38}\times 57$ miles = 7.5 miles
Answer:
A
Step-by-step explanation:
8.5 x 8.5= 72.25
so basically it's the closest answer
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.
