A ball is thrown into the air with an upward velocity of 12 meters per second. Its height h in meters after t seconds is given by the function h=-16 + 12t + 5. How long will it take the ball to reach its maximum height? What is the ball's maximum height? What is the range of the function? look at the picture as well
Answers
Answer:
-16(5/8)^ 2 + 20(5/8) + 6 = 12.25 ft
Step-by-step explanation:
h = -16t^ 2 + 20t + 6 the ball will hit the ground when h = 0
0 = -16t^2 + 20t + 6 factor
0 = ( -8t - 2 ) ( 2t - 3) set each factor to 0
-8t - 2 = 0 and 2t - 3 = 0
-8t = 2 2t = 3
t = -2/8 = - 1/4 sec t = 3/2 sec = 1.5 sec
Max hit will be reached at [ -b / 2a ] sec = -20 / [ 2(-16)] = 20/32 = 5/8 sec
-16(5/8)^ 2 + 20(5/8) + 6 = 12.25 ft

Find the median, first quartile, third quartile, and interquartile range of the data.
68, 74, 67, 72, 63, 70, 78, 64, 76
Answers
Given:
The data set is:
68, 74, 67, 72, 63, 70, 78, 64, 76
To find:
The median, first quartile, third quartile, and interquartile range of the data.
Solution:
We have,
68, 74, 67, 72, 63, 70, 78, 64, 76
Arrange the given data in ascending order.
63, 64, 67, 68, 70, 72, 74, 76, 78
Now divide the data in two equal parts.
(63, 64, 67, 68), 70, (72, 74, 76, 78)
So, the median of the given data set is 70.
Divide each parenthesis in two equal parts.
(63, 64), (67, 68), 70, (72, 74), (76, 78)
Now, the first quartile is:
[tex]Q_1=\dfrac{64+67}{2}[/tex]
[tex]Q_1=\dfrac{131}{2}[/tex]
[tex]Q_1=65.5[/tex]
The third quartile is:
[tex]Q_3=\dfrac{74+76}{2}[/tex]
[tex]Q_3=\dfrac{150}{2}[/tex]
[tex]Q_3=75[/tex]
The interquartile range (IQR) is the difference between third quartile and first quartile.
[tex]IQR=75-65.5[/tex]
[tex]IQR=9.5[/tex]
Therefore, median is 70, first quartile is 65.5, third quartile is 75 and the interquartile range is 9.5.

Il utilise un quart de ce qui reste dans le conteneur pour laver ses vêtements.
La fraction de ce qu'il utilisait pour laver ses vêtements =

Answer: y = 2x + 8/3
Step-by-step explanation:
6x - 3y +8 = 0
-3y + 8 = -6x
-3y = -6x - 8
y = 2x + 8/3

4) In A ABC, m B = 25°, b = 12 and c = 21. Find all possible m2 C to the
nearest degree.
Answers
Answer:
47.7° or 132.3°
Step-by-step explanation:
In A ABC, m B = 25°, b = 12 and c = 21. Find all possible mC to the
nearest degree.
We solve the above question using Laws of sines.
The formula is given as
b/sin B = c/sin C
b = 12
B = 25°
c = 21
C = ?
Hence:
12/sin 25 = 21/sin C
Cross Mulitiply
= 12 × sin C = sin 25 × 21
sin C = sin 25 × 21/12
C = arc sin (sin 25 × 21/12)
C = 47.7°
The second possible value of C =
180° - 47.7°
= 132.3°
Therefore, all the possible values of mC = 47.7° or 132.3°

What is the domain of the function y = l n (x + 2)
A. x < -2
B. x > -2
C. x < 2
D. x > 2
Answers
Answer:
Option B.
Step-by-step explanation:
For a function f(x), the domain is the set of all the possible values of x that can be used in the function.
We know that the natural logarithm is only defined for positive real numbers.
So, the function:
Ln(x + 2)
Works always that
x + 2 > 0
So we can just solve this inequality for x, and that will give us the domain of the function.
To isolate x, we just need to subtract 2 in both sides of the inequality.
x + 2 - 2 > 0 - 2
x > - 2
This is the domain of the function.
The correct option is B.
Answer:
b.x>-2
