Answer:
First of all, lateral means the sides of the can in this case.
Calculate the surface area of the can, subtract the area of the top and bottom which are two circles, and theres the answer!
Step-by-step explanation:
1. SA= 2πrh+2πr^2
= 2(π)(1.3)(4) + 2(π)(1.3^2)
= 43.29- (π1.3^2)^2
=15.09
Please note that ^(a number) means to the power of (that number). Hope this helps!
30 minutes is 1/2 an hour so 16 x 2 = 32 the phone charges at 32% per hour.
1. Multiply the number of hours by the rate and add the original 10% to that for total charge:
Y = 0.32h + 0.10
2. The phone charges at 16% every thirty minutes which is a half hour so you double the rate it charges to get the rate per hour. The phone charges at 32% per hour that it is charging.
Answer:
- The degree of the polynomial is even.
- The leading coefficient is positive.
- The polynomial has four zeros.
Step-by-step explanation:
As shown at the graph
The polynomial function intersects with x-axis at 4 points and opens up.
So, we can deduce that:
1) The degree of the polynomial is the fourth degree because it have 4 points of intersection with the x-axis
So, The degree of the polynomial is even
2) As the curve opens up ⇒ The leading coefficient is positive
Leading coefficients are the numbers written in front of the variable with the largest exponent.
3) The polynomial has four zeros because it have 4 points of intersection with the x-axis
The zeros of the polynomial are the values of x at which y = 0
