Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -5t^2 + 14t + 3[/tex]
Required
Time the drop will hit the ground
When the drop hits the ground,
[tex]h(t) = 0[/tex]
So, we have:
[tex]0 = -5t^2 + 14t + 3[/tex]
Rewrite as:
[tex]5t^2 - 14t - 3 = 0[/tex]
Expand
[tex]5t^2 + t - 15t - 3 = 0[/tex]
Factorize
[tex]t(5t + 1) -3(5t + 1) = 0[/tex]
Factor out 5t + 1
[tex](t -3)(5t + 1) = 0[/tex]
Split
[tex]t -3 = 0[/tex] or [tex]5t + 1 = 0[/tex]
Solve for t
[tex]t = 3[/tex] or [tex]5t = -1[/tex]
Time cannot be negative.
So:
[tex]t = 3[/tex]
2. Jill swam 200 meters in 2 minutes 42 seconds. If each lap is 50 meters long,
which is MOST LIKELY to be her time, in seconds, per lap?
Answer:
40.5
Step-by-step explanation:
there are 4 laps in 200 metres.
(200m÷50m)
2min 42 sec=120 sec+42sec (162sec)
so,
162÷4=40.5

The perimeter is the sum of the sides
Starting from the left and going clockwise, then
9 + (10 - 6) + (9 - 2) + 6 + 2 + 10
= 9 + 4 + 7 + 6 + 2 + 10
= 38
Answer: 35 cm
Step-by-step explanation: to find the perimeter you add all the sides but sense there is on side that doesn't have a number you subtract 2 from nine then add all the sides plus 7.

When flipping a coin, what is the probability of flipping heads and then heads?
Answer:
answer: 1/4
Step-by-step explanation:
Hello Love! The answer would be 1/4 because each time when flipping the coin you have a probability of 1/2 because you have equal chances of getting heads or tails then you multiply 1/2 by 1/2 and get 1/4
Answer: 1/4
Step-by-step explanation: In this problem, we are flipping a coin and we want to find the probability of flipping heads and heads.
Flipping a coin twice are events because the outcome of flipping 1 coin
does not affect the outcome of flipping the other coin.
First, find the probability of each event.
The probability of flipping headsnon the first coin toss is 1/2 since there
is 1 favorable outcome, flipping heads, and 2 possible outcomes.
The second flip will also be 1/2.
Now multiply the probabilities to get 1/4.
If x² = 12x – 7 is solved by completing the square,
one of the steps in the process is
1) (x-6)=-43
2) (x+62 = -43
3) (x-6)2 = 29
4) (x + 6 = 29
Answer: i believe the answer is 4).
Step-by-step explanation:
Because x= + [tex]\sqrt{ 29[/tex] + 6
How many solutions does the system of equations below have?
y=x+2
y=x-1
A one
B two
С none
D infinitely many
Answer:
C
Step-by-step explanation:
Answer:
C: none
Step-by-step explanation:
Here we have two separate functions named 'y.' Eliminate 'y' temporarily by equating these functions together:
x + 2 = y = x - 1
Subtracting x from both sides, we get:
0 + 2 = y = 0 - 1, or
2 = -1
This is never true, so C is the correct answer: NO solutions.
An easier way in which to do this problem is to visualize the graphs of
y = x + 2 and y = x - 1. The graphs are parallel straight lines; they never intersect, and therefore we can conclude "no solution."

Solve the inequality. Enter the answer as an inequality showing the value of the variable to a number (like s < 1/2, or w = 1).
2x < -10
Answer:
x < -5
Step-by-step explanation:
For the most part, you solve inequalities the same way you solve equations. So for this one, we just needed to divide both sides by 2.
The solution to the inequality is: x < -5. To solve the inequality 2x < -10, follow these steps:
1. Divide both sides of the inequality by 2 to isolate x.
2. Remember to reverse the inequality sign when dividing by a negative number.
Step 1: Divide both sides by 2:
(2x) / 2 < (-10) / 2
Step 2: Simplify:
x < -5
The solution to the inequality is:
x < -5

what is the surface area of 150 boxes
Answer:
Well since there aren't any specifics all you can be given is an equation on how to solve it, if a box has 6 sides and it's a cube then it will just be L*W=A then multiply that area by 6, that gives you the full surface area and if you want it for 150 boxes then just multiply whatever you got for the surface area by 150. It will be different if it's a rectangular box though, with that you must solve the surface area for 3 different pieces and multiply them all by 2 then add them all up and you get the surface area of that shape, then you multiply by 150 and that's your answer.

Peter says If you subtract 14 from my number and multiply the difference by -2, the result is -44 What is Peters number?
Answer:
36
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Let the number be x, then
First subtract 14 from number x, then
x - 14
Now multiply difference by -2, results -44
(x - 14) × -2 = -44
By solving equation,
-2X + 28 = - 44
- 2X = -44 - 28
X = -72 ÷ -2
x = 36
So, Peter's number is 36.
