Answer:
523.5miles
Step-by-step explanation:
Marcus traveled 65mph for 3.5hrs and 74mph for 4hrs. To find his total traveled distance we need to multiply the mph by the number of hours.
65x3.5=227.5mi
74x4=296mi
Add the number of miles together.
227.5+296=523.5miles
Hope this helps :)
Hey there, Valensolar! I would usually explain my answer, but in this case, I cant use any of the symbols required. But the answer is no. The number 1 can NOT be an additive identity. I hope this helps! :D
Answer:
Jamison is not correct
Step-by-step explanation:
According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.
These roots comprises of real roots and imaginary roots.
The given function is
![f(x) = {x}^{4} - {x}^{3} - 19 {x}^{2} - x - 20](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%7Bx%7D%5E%7B4%7D%20%20-%20%20%7Bx%7D%5E%7B3%7D%20%20-%2019%20%7Bx%7D%5E%7B2%7D%20-%20x%20-%2020%20)
Based on the Fundamental Theorem of Algebra, this function should have four roots.
The graph of the function only reveals real zeros and not the imaginary zeros.
So aside −4 and 5, there are two complex zeros
Answer:
x = 9
Step-by-step explanation:
The sum of interior angles in a triangle is 180°.
Let's say the measure of the angles are 3x, 10x, and 7x.
3x + 10x + 7x = 180
20x = 180
<u>x = 9</u>
