The function h(0) = -16t2 + vt + 10 gives the height of a platform diver above the water, in feet, t seconds after
Complete Question:
The height of a diver jumping from a diving platform is about [tex]h(t)= 16t^2 +11t+10[/tex], where h is the height of the diver in feet above the water and t is the time measured in seconds, when diving from a platform about 34.3 feet above the water with an upward initial velocity of 11 ft/sec.. After how many seconds is the diver's height above the water 15 feet?
Answer:
0.3125 seconds
Step-by-step explanation:
Given
[tex]h(t)= 16t^2 +11t+10[/tex]
Required
Time when the diver is above 15ft
This implies that h(t) = 15
So, we have:
[tex]15= 16t^2 +11t+10[/tex]
Collect Like Terms
[tex]0= 16t^2 +11t+10 - 15[/tex]
[tex]0= 16t^2 +11t-5[/tex]
[tex]16t^2 +11t-5=0[/tex]
Expand:
[tex]16t^2 + 16t - 5t - 5 = 0[/tex]
Factorize:
[tex]16t(t + 1) - 5(t + 1) = 0[/tex]
[tex](16t - 5)(t + 1)=0[/tex]
Split
[tex]16t - 5 = 0[/tex] or [tex]t + 1 = 0[/tex]
[tex]16t = 5[/tex] or [tex]t + 1 = 0[/tex]
Solve for t
[tex]t = 5/16[/tex] or [tex]t = -1[/tex]
[tex]t = 0.3125[/tex] or [tex]t = -1[/tex]
But time can't be negative. So:
[tex]t = 0.3125[/tex]
Hence, it will take the diver 0.3125 seconds to be at a height above 15 feet
It will take t = 0.3125 seconds is the diver's height above the water 15 feet.
Given ,
The height of a diver jumping from a diving platform is h
h(t) = [tex]-16t^{2} + vt + 10[/tex]
The diver's height above the water 15 feet
Velocity = v = 11 ft per second
We have to find, t seconds is the diver's height above the water 15 feet.
According to the question,
[tex]h(t) = -16t^{2} +vt+10[/tex]
Where v = 11, h(t) = 15
15 = -16[tex]t^{2}[/tex] + 11t + 10
15 - 10 = [tex]-16t^{2} + 11t[/tex]
5 = [tex]-16t^{2} +11t[/tex]
[tex]16t^{2} -11t +5= 0[/tex]
[tex]16t^{2} -16t - 5t + 5 = 0[/tex]
16t ( t - 1 ) - 5 ( t + 1 ) = 0
(16t - 5 ) ( t + 1 ) = 0
16t - 5 = 0
16t = 5
t = [tex]\frac{5}{16}[/tex]
t = 0.3125
And t + 1 = 0
t = -1
Time can not be negative so we can't take t = -1 .
So, The required value of time is t = 0.3125
Hence, it will take t= 0.3125 seconds is the diver's height above the water 15 feet.

Square PINT has vertices N(4, 2) and T(3, 8). What is the area of square PINT?
Answer: the answer is 37
Step-by-step explanation: someone said it was incorrect but it’s correct trust me my teacher gave us the answer
The area of the square PINT will be 37 square units.
What is an area of a square?The space occupied by any two-dimensional figure in a plane is called the area. Here we have three shapes a triangle, a rectangle, and a parallelogram.
Given that Square PINT has vertices N(4, 2) and T(3, 8). The area of the square will be calculated by finding the distance between two points N(4, 2) and T(3, 8), and squaring it.
The length of the line segment bridging two points on a plane is known as the distance between the points.
Area = Distance² = ( x₂ - x₁ )² + ( y₂ - y₁ )²
Area = Distance² = ( 4 - 3 )² + ( 8 - 2 )²
Area = Distance² = (1 )² + ( 6 )²
Area = Distance² = (1 )² + ( 6 )² = 37 square units
Therefore, the area of the square PINT will be 37 square units.

Evaluate x/y if f x = 14 and y=-2
Answer:
-7
Step-by-step explanation:
First, we need to substitute x in as 14 since that is what x is equal to.
1. x / y => 14 / y
Next, we need to substitute y in as -2 since that is what y is equal to.
2. 14 / y => 14 / -2
Now to solve it;
3. 14 / -2 => -7
So now we now that x / y equals -7 when x = 14 and y = -2.

32. The length of a rectangle measures six more than the width. The perimeter of the rectangle is 38.
What are the dimensions of the rectangle?
Answer: 12.5
You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."
subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"

Answer:
d= 99 e= 81 f= 99
Step-by-step explanation:
Answer:
d = 90
e = 81
f = 99
Step-by-step explanation:
First, find e because you can figure it out by vertical angles. 81 and e are vertical so e is 81. To find f, you subtract 180 by 81 because it's a straight line which is 99. So f is 99. To find d, you can use the right angle next to it. 180-90 is 90. So d is 90.

how to i find the missing 2 angles
Answer:
therefore, x is 71 degrees
Step-by-step explanation:
we know that the exterior angle is 142 degrees.
we also know that we have to find x, which is labeled two times as an interior triangle (in the same triangle), so they must be the same degree.
there are different ways to solve this but the easiest way is this:
exterior angle = opposite interior angle 1 + opposite interior angle 2
142 degrees = x + x
142 degrees = 2x
142/2 = x
x = 71
therefore, x is 71 degrees
What is y?
And please show work!
Answer: 97 degrees
Step-by-step explanation:
I drew some letters on your attachment to make it easier for you to understand.
To find angle y you need to find angle x first, you do that by doing (180=A+B+C) and you solve for A which is x degrees (A=180-B-C)
When you use angle C you must combine the 26 degrees and 55 degrees because if you use only 55 let's say, that would be the angle for triangle CDB, and we need C for triangle ABC.
So: A=180-42-81 -> A=57 degrees
Now you know Angle A (57 degrees) and Angle ACD (26 degrees)
All you have to do to find Y is to do: y=180-x-26
So y would be: 97 degrees
Keep in mind this is one of two solution methods I can see, if you want me to show you the other one as well just tell me in the comments, you are welcome.
