Step-by-step explanation:
Water is shot straight up out of a water soaker toy.
The quadratic function y = –16x2 + 32x models the
height in feet of a water droplet after x seconds. How
long is the water droplet in the air?
Help!
Answer:
The water droplet is in the air for two seconds.
Step-by-step explanation:
You can solve this by finding the times at which its height is zero. The lesser of the two values will be upon launch, and the greater upon landing:
y = -16x² + 32x
Let y = 0
-16x² + 32x = 0
factor -16 out:
x² - 2x = 0
complete the square:
x² - 2x + 1 = 1
and solve for x
(x - 1)² = 1
x - 1 = ±1
x = 1 ± 1
x = 0, 2
So the water is at a height of zero at zero seconds and two seconds. It's thus in the air for two seconds.
Solve for x*
55°
x + 74
I
54°

Answer:
y = 16.3
Step-by-step explanation:
Based on the altitude theorem of a right triangle, we have:
14 = √(12*y)
Square both sides
14² = 12*y
196 = 12y
Divide both sides by 12
196/12 = 12y/12
16.3 = y
y = 16.3 (nearest tenth)

Step-by-step explanation:
can someone help :(!
Answer:
A
Step-by-step explanation:
You should know the area of a circle, A = πr².
So, all you need to find is the area of half a circle, or A = [tex]\frac{1}{2}[/tex] πr²
We see that the radius is half of the diameter or r = 6 in.
A = [tex]\frac{1}{2}[/tex] (3.14)(6)²
A = 56.52 in²
The standard form of an equation of a circle with center at
(h, k)
and radius r is _____.
(y − h)2 + (x − k)2 = r2
(x − h)2 − (y − k)2 = r2
(y + h)2 − (x + k)2 = r2
(x − h)2 + (y − k)2 = r2
(x + h)2 − (y + k)2 = r2
Answer:
The standard form of an equation of a circle with center at (h, k) and radius r is
(x - h)² + (y - k)² = r²

Question 10 of 10
James wants to tile his floor using tiles in the shape of a trapezoid. To make
the pattern a little more interesting he has decided to cut the tiles in half
along the median. The top base of each tile is 15 inches in length and the
bottom base is 21 inches. How long of a cut will John need to make so that
he cuts the tiles along the median?
O A. 18 inches
B. 36 inches
O C. 3 inches
D. 6 inches
Answer:
18 inches
Step-by-step explanation:
The median of a trapezoid is the average of the lengths of the bases.
15 + 21 = 36
36 ÷ 2 = 18

Please i neeed helpp as fast as i needdddd i only got 20 mincyes
Answer:
Suppose that you have a random point (x, y), and now you do a dilation from the origin with a scale factor of k.
Then the new coordinates of the point are:
(k*x, k*y)
Now, in this question, we have a dilation of scale factor k = 1/2.
Then if we start with the point (x, y), after the dilation we will have the point (x/2, y/2)
Now you can notice that instead of this, in the table we have (2*x, 2*y)
So this is the error, the transformation is not correctly calculated.

Answer:
Step-by-step explanation:
1) Find the Mean of all the numbers.
3+4+5+7+10+12+15=56
56/7=8 mean is 8
Now We Calculate Standard Deviation:
S=[tex]\sqrt{(3-8)^2+(4-8)^2+(5-8)^2+(7-8)^2+(10-8)^2+(12-8)^2+(15-8)^2}[/tex]
You take each number from the problem i.e 3,4,5...
and then you subtract the mean from it and then square it.
S=[tex]\sqrt{(-5)^2+(-4)^2+(-3)^2+(-1)^2+(2)^2+(4)^2+(7)^2}[/tex]
S=[tex]\sqrt{25+16+9+1+4+16+49}[/tex]
S=[tex]\sqrt{120}[/tex]
S=[tex]\sqrt{120}/7[/tex]
7 is the amount of data units given in the problem.
120/7=17.1428571429
[tex]\sqrt{17.1428571429}[/tex] =4.1403933560541
