The ball will hit the ground at 0.125 seconds
<h3>
Quadratic function</h3>
The equation of the function is a quadratic function, and the function is given as:
When the ball hits the ground, the value of h is 0.
So, the equation of the function becomes
Subtract 2t from both sides of the equation
Divide both sides by -2t
Divide both sides by 8
Hence, the ball will hit the ground at 0.125 seconds

Question: How do you solve [3.2 x (6.1 x 6.3)] - 2.8 with PEMDAS?
PEMDAS is the order of operations with which you solve an equation. So first parentheses, then exponents, then multiplication, then division, then addition, and last subtraction.
Answer: First, you solve the parentheses in the parentheses:
>6.1 x 6.3 = 38.43
Now ur equation is: (3.2 x 38.43) - 2.8
Now you solve what's inside this parentheses:
>3.2 x 38.43 = 122.976
Now you do the subtraction, because you have already solved all of what's in the parentheses:
>122.976 - 2.8 = 120. 176
And so, your answer is 120.176
This is what your equation should look like when you're solving:
>[3.2 x (6.1 x 6.3)] - 2.8 = y
>[3.2 x (38.43)] - 2.8 = y
>(3.2 x 38.43) - 2.8 = y
>122.976 - 2.8 = y
>122.976 - 2.8 = 120. 176
Answer:
Step-by-step explanation:
The relative speed of the two trains is the sum of the speeds they are traveling. (If you're on either of the trains, this is the speed you appear to be moving when you see the other train.) In our problem, the relative speed of the two trains is 70 mph + 60 mph = 130 mph. What if the trains were traveling in the same direction? Then we'd need to subtract the speed of the slower train from the speed of the faster train, and their relative speed would be 10 mph.
Answer:
Carlota is not correct
Step-by-step explanation:
A ratio represents relationship between of two or more things.
Ratio of minutes to gallons of water flowing through a garden hose
Here,
Also,
It's given that an equivalent ratio of minutes to gallons is
Now,
Therefore,
Carlota is not correct
SOLUTION:
Alternate angles on paralell lines.
This means:
2x + 10° = 62°
2x = 62 - 10
2x = 52
x = 52 / 2
x = 26
Sorry, I tried to answer this but I only got this far. I'm not exactly sure about the ? < x < ? as my answer didn't give an answer with > or <. Unless there are different numbers which you can put for your answer based on what ( x ) is equal to, I'm not sure what the answer is & I doubt that they would allow for multiple answers.
