(pre-calc) Use Limit Laws to determine the limit of a(n). It is not -∞, so what answer is it and why?
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
a(n) = -1
Hence the limit of the function as the variable n tends to minus infinity is -1

Calculating Object's Height A boulder sitting on the edge of a cliff has 15,500 J of gravitational potential energy and a mass of 500 kg. Determine the height above Earth's surface that the boulder rests. P.E. = mass × 9.8 (gravity) × height
The height above Earth's surface that the boulder rests is 3.16m.
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

Slope is -7/4
Easy math problems!!!!!
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

Which equation represents the line that passes through the points (4, 6) and (−2, −1)?
Find the slope first by using rise/run
[tex]m=\frac{6-(-1)}{4-(-2)}\\m=\frac{6+1}{4+2}\\m=\frac{7}{6}[/tex]
[tex]y=mx+b\\y=\frac{7}{6}x+b[/tex]
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.
From y = mx+b, the equation is.
[tex]y=\frac{7}{6}x+\frac{4}{3}[/tex]

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the total number of guest is x;
and, the Total Cost of Hosting a Private Party be y;
here it is given that :
A restaurant charges a $100 setup fee, plus $15 per guest, to host a private party then, this van be shown in linear equation as :
y = 15x + 100
Now, for 45 number of guests that is x = 45, then y will be :
y = 15x + 100
y = 15 x 45 + 100
y = 675 + 100
y = 775 $
Thus, the restaurant charge 775 $ in total for a private party with 45 guests.

Graph a line that contains the point (-5,-3) and has a slope of -2
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.
15 total kids were at the park. 6 of them were girls. What % of the kids were girls?
Answer:
40%
Step-by-step explanation:
6/15 = 0.4
0.4 * 100 = 40%
Answer:
40%
Step-by-step explanation:
Since there are 15 total kids and 6 of them are girls, we can write this question as the fraction 6/15.
6/15 is 0.4 and to get the percent you would multiply by 100%.

some birds migrate 20,000 miles. if 1 mile equals 1.6 km, calculate the distance these birds fly in km
If 1 mile equals 1.6 km, the distance these birds fly is 32000km.
Here we have,
Total miles = 20,000
Given, 1 mile = 1.6 kilometer
Thus, total km travel = 20000 x 1.6
Total km travel = 32000 km
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.
Thus, some bird species travel 20,000 miles. These birds travel 32000 kilometers if a mile is equal to 1.6 kilometers.

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.
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
