Answer:
y=4x+4
Step-by-step explanation:
slope intercept form is y=mx+b
m is slope
B is y intercept
To find slope we use y2-y1/x2-x1
16-(-4)/3-(-2)
20/5
4 is the slope
We can fill this in
y=4x+b
To find b we fill in any coordinates
-4=4(-2)+b
-4=-8+b
+8. +8
4=b
Now we can fill it in
y=4x+4

Elouise and Marcus are 20km apart.
There is a lake due west of Elouise that is also 10√3 km due north of Marcus.
Work out the bearing of Marcus from Elouise
Elouise and Marcus are 20 km apart. There is a lake due west of Elouise that is also 10√3 km due north of Marcus, so 22.36 km distance the bearing of Marcus from Elouise.
What is Pythagoras theorem?According to the Pythagoras theorem, the square of the hypotenuse of a right-angled triangle equals the sum of the squares of the other two sides. The formula for this theorem is c² = a² + b², where c is the hypotenuse and a and b are the triangle's two legs. Pythagoras theory triangles are another name for these triangles.
At first assume a triangle, In the triangle, assume Elouise at the point A and Marcus at the point B, and the lake at the C point.
Given that,
Elouise and Marcus are 20 km apart (AB)
There is a lake due west of Elouise that is also 10√3 km due north of Marcus (BC)
Now, according to a Pythagoras theorem,
(AC)² + (AB)² = (BC)²
or, (AC)² = (BC)²- (AB)²
or, (AC)² = (10√3)² - (20)²
or, AC = [tex]\sqrt{500}[/tex]
or, AC = 22.36 km
So, distance bearing of Marcus from Elouise is 22.36 km.

Can someone help? Solve for a given that the height of the triangle is 3 centimeters and each of the legs are 6 centimeters. I also need the centimeters please !!
Answer:
6√3 centimeters
Step-by-step explanation:
This is an isosceles triangle because two of the sides are the same. We can divide this into two triangles to make two right triangles, and use the Pythagorean theorem. The base (a) will be divided by 2.
Pythagorean theorem: a^2 + b^2 = c^2
a and b are the legs of the triangle. c is the hypotenuse.
Let's replace the variables with the given information we know.
The hypotenuse is 6. One of the legs is 3. the other leg is a/2.
3^2 + b^2 = 6^2
9 + b^2 = 36
b^2 = 27
b = √27 = 3√3
Since this was for half of the base, we will multiply it by 2.
3√3 x 2 = 6√3
That is our answer.

what is the sum of the infinite geometric series?25 minus 10 plus 4 minus eight fifths plus continuing the series diverges.
Answer:
Geometric Sequence
Finding the sum
The sum of the infinite geometric series 3/4 -9/16+27/64 -81/256+ ...is 3/7.
Solution:
Geometric Series Sum Formula: S = a₁/1 - r
Given: a₁ = 3/4
a₂ = -9/16
a₃ = 27/64
a₄ = -81/256
1. Find the common ratio.
a_n = a₁r ⁿ ⁻ ¹
a₂ = a₁r ⁿ ⁻ ¹
-9/16 = 3/4 r ² ⁻ ¹
-9/16 = 3/4 r
2. Divide both sides of the equation by 3/4 to find r.
-9/16/3/4 = 3/4 r/3/4
(-9/16)(4/3) = r
-36/48 = r
-3/4 = r
3. Using r = -3/4, find the sum of the infinite geometric series 3/4 -9/16 +27/64 -81/256+ ...
S = a₁/1 – r
S = 3/4/1 – (-3/4)
S = 3/4/1 + ¾
S = 3/4/4/4 + 3/4
S = 3/4/7/4
S = (3/4)(4/7)
S = 12/28
S = 3/7
4. Therefore, the sum of the infinite geometric series 3/4 -9/16+27/64 -81/256+ ...is 3/7.

In triangle LMN, the measure of angle L is 50° and the measure of angle M 70°. What is the measure of the exterior angle to angle N?
Answer:
120°
Step-by-step explanation:
The 3 angle measures of a triangle will always equal 180.
Since we've already got two angles, all we need to do is a simple equation to get our missing angle:
180-(50+70)=60
Now that we've got the missing angle, we need to calculate the exterior angle, the thing we're here for. We know (hopefully at this point) that an exterior angle and its interior angle are a linear pair, meaning that the two add up to 180. Knowing this, we can do this equation to finish off the question:
180-60=120
And there's your answer, 120°
There's also a shorter way of doing this, let me know if you'd like to see it. But for now, hope I helped!

What are coordinates?A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.
You do the reverse to determine a point's coordinates in a coordinate system.
Start at the point, then move up or down a vertical line until you reach the x-axis. Your x-coordinate is shown there.
To find the y-coordinate, repeat the previous step while adhering to a horizontal line.
So, we must discover the halfway point between Lan's house and Joe's house in order to get the diner's coordinates.
The following equation will determine the midway between any two points:
M(x1 + x2/2, y1 + y2/2)
There are (4, 4), the point, and the point replaces the specified values:

A particle of mass mm moves in the plane with coordinates ( x ( t ) , y ( t ) )(x(t),y(t)) under the influence of a force that is directed toward the origin and has magnitude k / \left( x ^ { 2 } + y ^ { 2 } \right)k/(x 2 +y 2 )—an inverse-square central force field.
An inverse-square central force field is [tex]mx^{''} = -\frac{kx}{r^3}\\ \\mx^{''} = -\frac{ky}{r^3}\\[/tex].
From Newton's second law of motion,
mass × acceleration = Force acting on the mass
Resolving the force F along x and y directions and applying Newton's second law of motion,
Using,
[tex]r = \sqrt{x^2+y^2}[/tex]
Therefore,
[tex]m\frac{d^2x}{dt^2} =-|F|cos \theta[/tex]
[tex]mx^{''} = -\frac{k}{x^2+y^2} \frac{x}{\sqrt{x^2+y^2} } \\\\mx^{''} = - \frac{kx}{(x^2+y^2)^\frac{3}{2} }\\ \\mx^{''} = - \frac{kx}{r^3}[/tex]
Where [tex]r = \sqrt{x^2+y^2}[/tex]
and cosθ = [tex]\frac{x}{\sqrt{x^2+y^2} }[/tex]
Similarly using,
[tex]r = \sqrt{x^2+y^2}[/tex]
we get,
[tex]m\frac{d^2y}{dt^2} = -|F|sin\theta[/tex]
[tex]mx^{''} = -\frac{k}{x^2+y^2} \frac{x}{\sqrt{x^2+y^2} } \\\\mx^{''} = - \frac{kx}{(x^2+y^2)^\frac{3}{2} }\\ \\mx^{''} = - \frac{kx}{r^3}[/tex]
Where [tex]r = \sqrt{x^2+y^2}[/tex]

Write an equation in point-slope form of the line that passes through the given point and with the given slope (-7,2); m =7
Answer:
Y = 7x + 51
Step-by-step explanation:
Point-slope form is in this form: y = mx + b where b is the y-intercept and m is the slope. We have the slope, and we already have a point that must be on the line. The only thing we need is the y-intercept, so we can plug in the given point and the slope to solve for b.
Plug in (-7, 2) for x and y and the slope(7) for m. This gives: [tex]2 = 7*-7 + b[/tex], or [tex]2 = -49 + b[/tex]. Now add 49 to both sides to isolate x, and we get that [tex]b = 51[/tex].

It is true, that the most level of confidence used in creating confidence intervals is 90%.
What is confidence interval?
A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.

Find the Base & Height of the triangle
Area =42 in^2
Answer:
Height: 6
Base: 14
Step-by-step explanation:
Area=42 in^2
height=x-1
base=2x
bh/2=42
Substitute in the values:
2x(x-1)/2=42
The 2s cancel out each other.
x(x-1)=42
x^2 - x =42
x^2 - x - 42=0
When we factor that, we get:
(x-7)(x+6)=0
x=7 or x=-6
We will take the positive answer.
height= x-1 = 7-1 = 6
base= 2x = 2(7) = 14
Now let's double check if we are correct.
6(14)/2
=84/2
=42
We are correct!
Answer:
Base: 14 and height: 6 OR Base: -12 and height -7
Step-by-step explanation:
First, set up a proportion. (base x height) divided by 2 on one side and 42 over 1 on the other.
[tex]\frac{2x(x-1)}{2}=\frac{42}{1}[/tex] Next, cross multiply. This involves taking the numerator of
one side (top) and multiplying it by the denominator
(bottom) of the other side.
84=2x(x-1) 42*2=84 and anything multiplied by 1 equals itself. Next,
distribute (multiply) the 2x by each term in the
parentheses.
84=2[tex]x^2[/tex]-2x 2x*x=2[tex]x^2[/tex]. 2x*-1=-2x. Next, subtract 84 from both sides.
0=2[tex]x^2[/tex]-2x-84 Now, you can simplify this by dividing by 2 on both sides.
0=[tex]x^2[/tex]-x-42 This is a quadratic equation, which means you have to
factor or use the quadratic formula. In this case, you can
factor by using product and sum. You have to find what
multiplies to -42 and adds to -1. Those numbers would be
-7 and 6. -7*6=-42 and -7+6=-1 Therefore, you will have
x-7 and x+6
0=(x-7)(x+6) Next, solve each equation with each binomial set equal
to 0. For x-7=0, x=7 because you add 7 to both sides. For
x+6=0, x=-6 because you subtract 6 from both sides.
x=7 x=-6
You can check if these values work by plugging them into the formula.
[tex]\frac{2x(x-1)}{2}- > \frac{2*7(7-1)}{2}- > \frac{14(6)}{2}- > \frac{84}{2}- > 42[/tex]. x can be 7.
[tex]\frac{2x(x-1)}{2}- > \frac{2*-6(-6-1)}{2}- > \frac{-12(-7)}{2}- > \frac{84}{2}- > 42[/tex] x can be -6

Ernesto guesses there are 69 marbles in a jar, but there are actually 60.
What is the percent error in Ernesto's guess?
Answer:
15%
Step-by-step explanation:
Since the problem is to find how much 69 is as a percent if 60 is 100%, we can use a rule of three, simple, direct proportion to do it:
60 = 100%
68 = x
x = 69x100/60
x = 115
That means 69 is 115% of 60, which means that the error is of:

if x is an integer it does not show the median of the 5 numbers to be greater than the average of the 5 numbers
What is a median in math?The value that, when a dataset is arranged, falls exactly in the center is the median. It is a measure of central tendency that distinguishes between the values' lowest and maximum 50%. Depending on whether you have an odd or an even number of data points, the processes for calculating the median change.
How do you find the median?Finding the middle number requires sorting all the data points and choosing the center one (or if there are two middle numbers, taking the mean of those two numbers). Example: When the numbers are arranged (1, 4, 7), the number 4 lies in the center, making it the median of 4, 1 and 7.
(1) x must be higher than one or three. It will be the median if it is 8 or fewer.
Consequently, if x = 7, then the list is 1, 3, 7, 8, 12, and median is 7, while the average is 31/5, which equals 6.2, and the answer is YES.
The list is 1, 3, 8, 8, 12, and the median is 8 if x = 8. Average = 32/5 = 6.4; if x = REALLY BIG, the list is 1, 3, 8, 12, and x; and the median is 8; the answer is YES. The answer to the question is NO since the average is REALLY BIG.
insufficient
(2) According to the aforementioned findings, x must be at least 9.
Depending on the amount of x, the list is either 1, 3, 8, x, 12, or 1, 3, 8, x.
The median and mean expressions are the same, regardless of whether order is appropriate:
Mean (average): 8 median = (1 + 3 + 8 + 12 + x)/5 = (24 + x)/5 mean (average):
The mean is at least (24 + 9)/5 = 33/5 = 6.6 since x is at least 9.
This is not convincing because the mean might be either millions or 6.6 (if x = 9) (if x is huge).

blackhawk tech gives four presidential scholarships. if there are 58 nominees, in how many ways can the scholarships be awarded?
If there are 58 nominees, then the number of ways in which scholarships can be awarded is 4,24,270.
What are the Permutation and Combination?
Permutations and combinations are the various ways in which objects from a set can be selected to form subsets, generally without replacement. When the order of selection is a factor, this selection of subsets is called a permutation; when it is not, it is called a combination.
If there are 58 nominees, and Blackhawk can give only four scholarships then the number of ways is =
[tex]=^nC_r\\\\=^{58}C_4\\\\=\frac{58!}{4!*54!}\\\\=\frac{58 * 57 * 56 * 55}{4 * 3 * 2 *1}\\\\=4,24,270[/tex]
Hence, if there are 58 nominees, then the number of ways in which scholarships can be awarded is 4,24,270.

Identify each of the following as rational or
irrational.
√23
104.42
√64
49.396
10.97846727460
Answer:
Irrational, rational, rational, rational, rational.
Step-by-step explanation:
√23 is an irrational number since the value of square root 23 cannot be expressed in the form of p/q.
104.42 this is a rational number! An irrational number has repeating values or just random numbers after the decimal point.
Here's an example...
Tell, does this number look rational?
4.2359712309458730495870192354870394587234098657293085412364781236409584790853467923456790324785098234570923845702398547 (and it goes on forever...and ever...and ever......)
√64 is a rational number. As we know that √64 = 8, a rational number.
49.396 with the 6 repeating is rational because we can express 49.39 as:
49.39 * 1 = 49.39 * 100/100 = 4939/100, and we are then left with
49.396- 49.39 = 0.006 (with the 6 repeating). A repeating decimal can be expressed as x/9, with the x representing all values before the repetition begins multiplied by 10.
10.97846727460 is rational because the decimal places stop, it is rational. Remember, an Irrational number is non-repeating and non-terminating. Since the number terminates, it is rational

[tex]h(4) = \frac{50}{5.5 + 8e^{-0.9(4)} }[/tex]
[tex]h(4) = \frac{50}{5.5 + 8e^{-3.6} }[/tex]
[tex]h(4) = \frac{50}{5.5 + 8(0.0273237) }[/tex]
[tex]h(4) = \frac{50}{5.5 + 0.21859 }[/tex]
[tex]h(4) = \frac{50}{5.71859 }[/tex]
h(4) = 8.7434
h(4) ≈ 8.7
Hence, the value of h(4) is 8.7
