I believe the answer is 21
2(8) 2×8 =16 that is how u do it
Answer:
Polynom degree: 5
Y intercept point: (0, 80)
Step-by-step explanation:
P(x)=(x+5)(x+4)²(x+1)²
When you expand, the highest power of x is 1 for first term (x+5), 2 for second term (x+4)² and again 2 for (x+1)². Overall, x⁵ will be the x term with highest power. So the degree of the polynom is 5.
The y intercept, i.e. intersection with OY axis, happens for x=0. Thus, P(0)=5×4²×1²=5×16=80. The y intercept point is (0, 80)
So 10.4mi = 1 hour
We need to find out how many miles 1.2 hours is.
1.) Well, the first step would be to multiply 1.2 on both sides of:
10.4mi = 1 hour
because that would make this number of miles is = to 1.2 hours which is wha we're looking for
1.2(10.4) mi = 1.2 hour
2.) Simplify
12.48 mi = 1.2 hour
3.) That means Gina rides 12.48 miles each day if she rides for 1.2 hours each day at a pace of 10.4 miles per hour :)
