Which statement describes a pattern in the shaded parts of the multiplication table?
Answers
A pattern in the shaded parts of the multiplication table is suitable for option b.(we multiply a number times itself to get each shaded number.)
Suppose we can use, option b,
We multiply a number times itself to get each shaded number,
Shaded parts of the multiplication table is ⇒ 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
We can write,
[tex]x^{2}[/tex] = x * x
Example:
1 = 1 * 1 = 1
4 = 2 * 2 = [tex]2^{2}[/tex]
9 = 3 * 3 = [tex]3^{2}[/tex]
16 = 4 * 4 = [tex]4^{2}[/tex]
25 = 5 * 5 = [tex]5^{2}[/tex]
36 = 6 * 6 = [tex]6^{2}[/tex]
49 = 7 * 7 = [tex]7^{2}[/tex]
64 = 8 * 8 = [tex]8^{2}[/tex]
81 = 9 * 9 = [tex]9^{2}[/tex]
100 = 10 * 10 = [tex]10^{2}[/tex]
Hence,
1 = [tex]1^{2}[/tex]
4 = [tex]2^{2}[/tex]
9 = [tex]3^{2}[/tex]
16 = [tex]4^{2}[/tex]
25 = [tex]5^{2}[/tex]
36 = [tex]6^{2}[/tex]
49 = [tex]7^{2}[/tex]
64 = [tex]8^{2}[/tex]
81 = [tex]9^{2}[/tex]
100 = [tex]10^{2}[/tex]
Therefore,
We multiply a number times itself to get each shaded number statement is suitable for a pattern in the shaded parts of the multiplication table.

The camera's horizontal distance of 26 feet from the the focus point on the floor.How high above the floor is the camera Round your answer to the nearest hundredth.
Answers
Answer:
8.95feet
Step-by-step explanation:
The set up is a right angled triangle where;
The camera's horizontal distance from the focus point = 26feet = Adjacent;
The height of the camera above the floor = Opposite = x
Angle of elevation = 19°
According to TOA in trig identity;
Tan theta = opp/adj
Tan 19 = x/26
x = 26tan 19
x = 26(0.3443)
X = 8.95feet
Hence the camera is placed at a height of 8.95feet above the floor

A seal went 15 below sea level to catch a fish. A sea lion dove 6 feet less than two times as deep as the seal to catch a larger fish. What expression represents the sea lion's position in relation to sea level?
Answers
Answer:
[tex]2\times 15-6 = 24\ below\ sea\ level[/tex]
Step-by-step explanation:
Given that:
Distance traveled by seal to catch the fish = 15 below sea level
Sea lion wanted to catch a larger fish so sea lion dove 6 feet lesser than two time the distance that the seal traveled.
To find:
The expression to represent the position of the sea lion in the sea.
Solution:
If the distance traveled by seal is represented by [tex]D[/tex] then as per the question statement:
Twice of [tex]D[/tex] = [tex]2\times D[/tex]
6 lesser than twice of [tex]D[/tex] = [tex]2\times D[/tex] - 6
Now, putting the value of [tex]D[/tex] = 15
Therefore, the expression to represent the sea lion's position w.r.to sea level.
[tex]2\times 15-6\\ = 24\ below\ sea\ level[/tex]

Which equation represents the line that passes through the points (4, 6) and (−2, −1)?
Answers
Find the slope first by using rise/run

We need to find the y-intercept. Substituting one of given ordered pairs. I will use (-2,-1).
Substitute x = -2 and y = -1 in the equation.
[tex]-1=\frac{7}{6}(-2)+b\\-1=\frac{7}{-3}+b\\-1=-\frac{7}{3}+b\\-1+\frac{7}{3}=b\\b=\frac{4}{3}[/tex]
Thus the y-intercept is 4/3.

What is Gravitational acceleration ?Gravitational acceleration can be defined as the acceleration of any object when the object is in free fall. or we can say that the gravitational acceleration is the quantity which describes the acceleration of free falling object within vacuum. It is denoted by g .
What is Potential Energy ?Potential energy is the stored energy of the object which is generally based on the relative position of the various parts of the object. It is also known as gravitational energy.
Formula of potential energy :
PE = mgh
where, PE = gravitational energy / potential energy
m = mass of object
g = gravitational acceleration
h = vertical height of object
According to question given:
PE = 15500J
m = 500kg
g = 9.8
As PE = mgh
therefore, h = PE / mg
i.e. h = 15500 / (500)(9.8)
h = 3.16m

hich of the relations given by the following sets of ordered pairs is not a function? {(5,2),(4,2),(3,2),(2,2),(1,2)} {(-4,-2),(-1,-1),(3,2),(3,5),(7,10)} {(-8,-3),(-6,-5),(-4,-2),(-2,-7),(-1,-4)} {(-6,4),(-3,-1),(0,5),(1,-1),(2,3)}
Answers
{(-4,-2),(-1,-1),(3,2),(3,5),(7,10)} is not the function .
• In mathematics, ordered pair is a pair of numbers which are written in a specific order. They are generally written in (x,y) form. For example (3,5) is a ordered pair.
• Function can also be represented by a set of ordered pairs. A function Is a set of ordered pairs in which no two different ordered pairs have same value of x coordinate.
Case 1 : {(5,2),(4,2),(3,2),(2,2),(1,2)}
No two ordered pair have the same value of x coordinate. So it is a function.
Case 2 : {(-4,-2),(-1,-1),(3,2),(3,5),(7,10)}
Two ordered pair have the same value of x coordinate (3,2) and (3,5). So, it can not be considered as a function.
Case 3 : {(-8,-3),(-6,-5),(-4,-2),(-2,-7),(-1,-4)}
No two ordered pair have the same value of x coordinate. So it is a function.
Case 4 : {(-6,4),(-3,-1),(0,5),(1,-1),(2,3)}
No two ordered pair have the same value of x coordinate. So it is a function.
Therefore, {(-4,-2),(-1,-1),(3,2),(3,5),(7,10)} is not the function.

(pre-calc) Use Limit Laws to determine the limit of a(n). It is not -∞, so what answer is it and why?
Answers
The limit of the function as the variable n tends to minus infinity is -1. Option C is correct
Limit of a functionGiven the limit of a function expressed according to the equation;
a(n) = 6n²-n-3n³/3n³+n-1
The value of the function if n tends to minus infinity is expressed as show:
a(n) = 6n²-n-3n³/3n³+n-1
Divide both all the terms by n³
a(n) = 6n²/n³-n/n³-3n³/n³/3n³/n³+n/n³-1/n³
a(n) = 6/n-1/n²-3/(3+1/n²-1/n³)
a(n) = 6/-∞ - 1/(-∞)²-3/(3+1/(-∞)²-1/(-∞)³)
a(n) = -3/3

Answer:
We can use the Pythagorean theorem to solve this:
The Pythagorean theorem states that the hypotenuse of a triangle (the longest side), squared is equal to the sum of the other 2 sides of the triangle, squared. It can be expressed as so:
c^2=a^2+b^2 where c represents the hypotenuse; a and b represent the other 2 sides.
Now that we have an equation we can solve:
c^2=8^2+8^2
c^2=64+64
c^2=128
Since there is no perfect square for 128 we need to put in in simplest radical form
c=√128
Find a number that has a perfect square and multiplies by another number to equal 128
c=√64 x 2
This can be rewritten as so:
c=√64√2
Now for the last step find another perfect square for 64 and have it outside the square like so:
c=8√2
There is no perfect square for 8 so this is in simplest radical form

Graph a line that contains the point (-5,-3) and has a slope of -2
Answers
Given:
The line contains the point (-5,-3) and has a slope of -2.
To find:
The graph of the line.
Solution:
The line contains the point (-5,-3) and has a slope of -2. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-(-3)=-2(x-(-5))[/tex]
[tex]y+3=-2(x+5)[/tex]
[tex]y+3=-2x-10[/tex]
Subtracting 3 from both sides, we get
[tex]y=-2x-10-3[/tex]
[tex]y=-2x-13[/tex]
So, the equation of line is [tex]y=-2x-13[/tex].
Putting x=0, we get
[tex]y=-2(0)-13[/tex]
[tex]y=0-13[/tex]
[tex]y=-13[/tex]
It means, the line also passes through (0,-13).
Plot the points (0,-13) and (-5,-3) on a coordinate plane and connect them by a straight line.
Therefore, the graph of given line is shown below.

the perimeter of a jamaican flag is 90 inches. the length is twice its width. find the dimensions of the flag
Answers
Answer:
width = 15 inches
length = 30 inches
Step-by-step explanation:
Finding the dimensions of a rectangular flag:[tex]\sf \boxed{\text{\bf Perimeter of rectangle =2*length + 2*width}}[/tex]
Let width = x inches
Length = 2*x = 2x inches
Perimeter = 90 inches
2 *length + 2* width = 90
2*2x + 2*x = 90
4x + 2x = 90
Combine like terms,
6x = 90
Divide both sides by 6,
x = 90/6
x = 15
Dimensions:
Width = 15 inches
Length = 2*15 = 30 inches.
