The longest two sides will be 4 each and the shortest two sides will be 2 each
Answer:
he travels 249 miles on saturday
Step-by-step explanation:
<u> 62.25 </u> <u> x</u>
1 = 4
you must multiple the distance travled in one hour by the number of hours of driving. In this case 4. This is if he did not change speeds ;)
4 x 62.25 = 249 miles
Hope this helps :) Please mark brainliest if you see fit :)
the greatest common multiple of 24 and 60 is 12

Answer:
(c) P(x) = x^4 +3x^3 -10x^2 -30x
Step-by-step explanation:
If the polynomial has integer coefficients, its complex or radical roots come in conjugate pairs. That is, -√10 is also a root. The four roots mean the polynomial has degree 4. That eliminates all but answer choice C.
Each root 'a' gives rise to a factor (x -a), so the factored polynomial is ...
P(x) = (x -0)(x -(-3))(x -√10)(x -(-√10))
P(x) = x(x +3)(x² -10) = x(x³ +3x² -10x -10)
P(x) = x^4 +3x^3 -10x^2 -10x
Answer:
10 seconds
Step-by-step explanation:
Find the zeros by equating f(x) to zero, that is
- 5x² + 50x = 0 ← factor out - 5x from each term
- 5x(x - 10) = 0
Equate each factor to zero and solve for x
- 5x = 0 ⇒ x = 0
x - 10 = 0 ⇒ x = 10
x = 0 denotes the time when the ball is struck and x = 10 when the ball returns to the ground.
Time in air = 10 - 0 = 10 seconds
