Answer:
Part A: 2.8 miles
Part B: 16.8 miles
Step-by-step explanation:
First, solve for how many miles Ted jogged in 1 day:
Variable x = number of miles
11.2/4 = x/1
Cross multiply
11.2 × 1 = 4 × x
11.2 = 4x
Divide both sides by 4
2.8 = x
He jogged 2.8 miles every day.
To find how many miles Ted would jog in 6 days, simply multiply his miles per day by the number of days he will jog:
2.8 miles × 6 days = 16.8 miles in 6 days
Answer:
x=-3
Step-by-step explanation:
We are given with the polynomial function <span>f(x) = 3x3 + 8x2 − 87x + 28 and is asked for the roots of the equation. The function given is a third order polynomial because the highest degree among the polynomials is 3.
In this case, to find the roots of the equation, we equate the function to zero, and then find the values of x.
Thus, the equation becomes </span><span>3x3 + 8x2 − 87x + 28 = 0. We can use an online polynomial finder to determine the roots of the equation. There are three roots of this equation since the order of this polynomial is 3 which are the following:
</span><span><span>Root 1: -7
Root 2: 1/3
Root 3: 4
All factors are real numbers, not imaginary.
