Answer:
10.29 u
Step-by-step explanation:
Given :-
Two points (7,4) and (-2,9) is given to us.And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}
[tex]:\implies[/tex] D =√[ (7+2)² +(9-4)²]
[tex]:\implies[/tex] D =√[ 9² +5²]
[tex]:\implies[/tex] D =√[ 81 +25]
[tex]:\implies[/tex] D = 10.29
Hence the distance between the two points is 10.29 units .Answer:
6.32455532034
Step-by-step explanation:
Pythogreans theorem:
a^2 + b^2 = c^2 (we want c)
(9-7)^2+(-2-4)^2 = c^2
2^2 + (-6)^2 = c^2
4+36 = c^2
c = sqrt(40)
c = 6.32455532034

What is the domain of the function y = l n (x + 2)
A. x < -2
B. x > -2
C. x < 2
D. x > 2
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

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
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

Le bidon de lessive de Kilian est rempli aux 2/3. Il utilise le quart de ce qu'il reste dans le bidon pour laver son linge. Combien lui reste-il de lessive dans le bidon?
Answer:
1/2
Step-by-step explanation:
D'après la question ci-dessus, on nous dit que:
La boîte à linge de Killian est remplie aux 2/3.
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 =
1/4 sur 2/3
= 1/4 × 2/3
= 1/6
La quantité de détergent qu'il reste dans le récipient est calculée comme suit:

4) In A ABC, m B = 25°, b = 12 and c = 21. Find all possible m2 C to the
nearest degree.
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°

A triangular prism with a ......... Triangle as its base will have three congruent, rectangular faces.
Answer:
Equilateral
Step-by-step explanation:
A triangular prism with an Equilateral Triangle as its base will have three congruent, rectangular faces. This is because an Equilateral triangle is one that has all its sides equal.
All the sides being equal thereby translates to it having 3 similar rectangular sides thereby justifying the prism having 3 congruent rectangular faces.
Given the equation of a line: 6x-3y+8=0,
Rearrange the equation in slope y-intercept form. [2]
Answer: y = 2x + 8/3
Step-by-step explanation:
6x - 3y +8 = 0
-3y + 8 = -6x
-3y = -6x - 8
y = 2x + 8/3
Answer:
y = 2x + 8/3
Step-by-step explanation:
slope y-intercept form => y = mx + b
=> -3y = -6x - 8
=> y = 2x + 8/3

PLEASE HELP Algebra 1
Answer:
9, y=9
Step-by-step explanation:
So, there is one thing we always need to remember to find the y intercept.
This is that the y intercept can always be found on the middle line of the graph, when x is at 0.
What we must do is look at the graph, look at where the function hits x=0, and see what the y value is.
In this case, when x equals 0, we can see that y is 9.
So the y intercept is 9.

Find the median, first quartile, third quartile, and interquartile range of the data.
68, 74, 67, 72, 63, 70, 78, 64, 76
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.

Answer:

change the sigh of x.
The function that represents a reflection of f(x) = (4) across the y-axis is g(x) = -4.
What is the reflection across the y-axis?A reflection across the y-axis will result in a mirror image of the original function. This means that any points on the right side of the y-axis will be reflected to the left side, and vice versa.
Start with the original function f(x) = (4). This function represents a horizontal line at y = 4.
To reflect the function across the y-axis, we need to change the sign of the x-coordinates of all the points. If a point on the original function is (x, y), the corresponding reflected point will be (-x, y).
Applying this reflection to the original function f(x) = (4), we get g(x) = -(4). The negative sign indicates the reflection across the y-axis.
Simplifying the function, we have g(x) = -4.
Therefore, the function that represents a reflection of f(x) = (4) across the y-axis is g(x) = -4.
