Let the numbers be x, x+1 and x+2 .
Equation :-
=> x+(x+1)+(x+2)=78
=> x+x+1+x+2=78
=> 3x+3=78
Subtract 3 from both sides..
3x=75
Divide both sides by 3 .
x=25
The three consecutive integers are
x , x+1 and x+2..In the place of x replace 25
∴ 25 , 26 and 27 are the three consecutive integers.
Given : Three consecutive integers have a sum of 78. Find the integers
Solution : Let's assume that the variable be x
The first one be x itself. Now, as it's consecutive the number should be increased by 1. So, let the second one be x + 1. As we know again it will be increased by 1. Hence, the third one be x + 1 + 1 i.e. x + 2
So, we got all the three now let's proceed
The result is 78
x + x + 1 + x + 2 = 78 3x + 3 = 78Taking 3 as common on the RHS of the equation
3(x + 1) = 78 x + 1 = 78/3 x + 1 = 26x = 26 - 1 x = 251st number = x = 25
2nd number = x + 1 = 26
3rd number = x + 2 = 27

If a=7, then the value of a² - 3a is ______.
a) -7
b) 35
c) -28
d) 28
Answer:
-7
Step-by-step explanation:
Given
a = 7
Since a = 7, then that would mean it the base of the exponent would be replaced to 7 to the second power.
So 7 x 7 = 49 ( multiplied twice itself)
--------------------------------------------
7×2-3×7=14-21 = -7

Use the vertical line test to determine whether the relation is a function. If not, identify two points a vertical line
would pass through.
Answer:
function
Step-by-step explanation:
The verticle line test is basically seeing if it is a function
It is a function when the verticle line touches only one point on the graph at once
For example, if the graph was a circle, and u drew a verticle line through it, it would touch two points on the graph, so it is NOT a function
But for this parabola, if you draw a verticle line at any point, it only touches one point of the graph, so it is a function
A vertical line test is a graphical approach for assessing if a curve in the plane reflects the graph of a function.
The correct option is C, function.
What is a Vertical-line test?The vertical line test is a method used to determine whether a graph represents a function or not. If a vertical line can be drawn on the graph such that it intersects the graph in more than one point, then the graph is not a function.
The graph of the given function, intersect the vertical axis or the y-axis at most one time, therefore, the given graph passes the vertical line test. Thus, it can be concluded that the given graph is a function.
Hence, the correct option is C, function.

Step-by-step explanation:
The volume of the triangular prism (green) is the area of the base multiplied by the height.
The base is the front surface which is a triangle with base 6 cm and height 7 cm.
The height of the prism is 6 cm.
V = AH
V = (1/2)bhH
V = (1/2)(6 cm)(7 cm)(6 cm)
V = 126 cm^3
The volume of the green triangular prism is 126 cm^3
The total volume of the composite solid is the sum of the two volumes.
Total Volume = 336 cm^3 + 126 cm^3
Total Volume = 462 cm^3

Answer:
1.3363
Step-by-step explanation:
The basic idea here is to find an expression for the direction vector between a point on L1 and a point on L2. Then, solve for the points on L1 and L2 that make that vector perpendicular to both lines L1 and L2. (The dot product of direction vectors is zero.) The distance between the points found is the shortest distance between the lines.
__
Let P be a point on L1. Then the parametric equation for P is ...
P = (6t, 0, -t) . . . . . . origin + t × direction vector
Let Q be a point on L2. The direction vector for L2 is given by the difference between the given points. It is (4-1, 1-(-1), 6-1) = (3, 2, 5). Then the parametric equation for Q is ...
Q = (3s+1, 2s-1, 5s+1) . . . . (1, -1, 1) + s × direction vector
The direction vector for PQ is ...
Q -P = (3s+1-6t, 2s-1, 5s+1+t)
The dot product of this and the two lines' direction vectors will be zero:
(3s+1-6t, 2s-1, 5s+1+t)·(6, 0, -1) = 0 = 13s -37t +5 . . . perpendicular to L1
(3s+1-6t, 2s-1, 5s+1+t)·(3, 2, 5) = 0 = 38s -13t +6 . . . perpendicular to L2
The solution to these equations is ...
s = -157/1237
t = 112/1237
Then (Q-P) becomes (94, -1551, 564)/1237, and its length is ...
|PQ| = √(94² +1551² +564²)/1237 ≈ 1.3363
The distance between the two lines is about 1.3363 units.
