Sarah kicked a ball in the air. The function f models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it

Answers

Answer 1
Answer:

The function that models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it is h(t) = vt - ¹/₂gt².

Equation of the motion of the ball

The equation of the motion of the ball is calculated from the second kinematic equation as shown below.

h(t) = vt - ¹/₂gt²

where;

  • h is the maximum height reached by the ball
  • v is the initial vertical velocity of the ball
  • g is acceleration due to gravity
  • t is time of motion of the ball

Thus, the function that models the height of the ball (in meters) as a function of time (in seconds) after Sarah kicked it is h(t) = vt - ¹/₂gt².

Is 27/51 equal to 18/34

Answers

yes.
27/51-18/34=0

Sam solved the following problem:-4x + 5 > 29
-4x + 5 - 5 > 29 - 5
-4x > -24
-4x/-4 > -24/-4
x > 6

What were his two mistakes?

Answers

Answer:

-4x > 24

x< 6

Step-by-step explanation:

-4x + 5 > 29

-4x + 5 - 5 > 29 - 5  (subtracted 5 on both sides)

To remove +5, Sam subtracted 5 on both sides. but 29-5 is 24

we always put the sign of greatest number . so its positive

-4x > 24 is correct

-4x/-4 > 24/-4

Dividing both sides by -4 is correct. But when we divide by negative number we need to flip the inequality sign . so > becomes <

x < 6

When measuring distance 12 beads are approximately equal to 6 erasers. how many erasers are equal to 18 beads? How many beads are equal to 42 erasers?

Answers

Well, since 12 divided by 6 would equal 2. So 9 erasers would equal to 18 beads (18 ÷ 2). 21 beads equal 42 erasers.
