Answer:
400
Step-by-step explanation:
You know that 80 is 20% of whatever number you are trying to get, and you want 100% of that number, so times 80 by 5 (20% times 5) to get your number.
Answer:
the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
Step-by-step explanation:
Answer:
Step-by-step explanation:
-2.8f + 0.7f - 14 - 4
- 2.1f - 18
x ≠ - 4, 3
the denominator of the fraction cannot equal zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the values that x cannot be
solve x² + x - 12 = 0
(x + 4)(x - 3) = 0
equate each factor to zero abd solve for x
x + 4 = 0 ⇒ x = - 4
x - 3 = 0 ⇒ x = 3
restrictions on x are : x ≠ - 4, 3
The ball seems to be traveling at its greatest average speed between x = 4 and x = 6 because the graph between 4 and 6 is a straight line, meaning the ball has reached the greatest possible speed.
