Answer:
The missing length is 80 degrees.
Step-by-step explanation:
Every triangle is equal to 180 degrees. If you add 64 and 36, you get 100. 180-100 is equal to 80, therefor x is equal to 80.

Answers
Answer:
a=4, b=-3
Step-by-step explanation:
If it is vertical, then the y coefficient must be equal to zero, which means b = -3. When y is 0, a*3=2*3+6, which means a=4.
Answer:
a=4
b=-3
Step-by-step explanation:
ax+by=2x-3y+6 is vertical and passes through (3,0) which means the equation should be equivalent to x=3.
If we want the y's to cancel we need -3y on lefy since we have it on right so b=-3.
So now the equation is ax=2x+6
If ax=2x+6 and x=3, by substitution property we have a(3)=2(3)+6.
Let's solve for a.
3a=6+6.
3a=12
a=12/3
a=4.
a=4
b=-3

Answer:
x = 60
Step-by-step explanation:
The sum of the angles in a triangle is 180
40 + x+20 + x = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x+60-60 =180-60
2x =120
Divide by 2
2x/2 =120/2
x = 60

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5). What is the equation of the line parallel to the given line with an x-intercept of 4? y = x +
Answers
Answer:
Step-by-step explanation:
A line that is parallel to the line that goes through (-3, -3) and (-1, 5) will have the same slope as the one we will find when we plug those numbers into the slope formula. Let's do that first:
[tex]m=\frac{5-(-3)}{-1-(-3)}=\frac{5+3}{-1+3}=\frac{8}{2}=4[/tex] so the line we need to write has a slope of 4. Moving on...
If the x-intercept we need is 4, that means that we need to understand what an x-intercept is. The x-intercept exists where y = 0; so what we need to do is to write the equation of the line that has a slope of 4 and passes through the point (4, 0). Doing that:
y - 0 = 4(x - 4) and
y = 4x - 16

Compute the product using (a) the definition where Ax is the linear combination of the columns of A using the corresponding entries in x as weights, and (b) the row-vector rule for computing Ax. If a product is undefined, explain why.
Answers
Answer:
When the number of rows or number of columns in the given matrix does not match the number of entries in the vector x.
When the number of columns in A [tex]\neq[/tex] the number of rows in B.
The matrix-vector is not defined.
Step-by-step explanation:
For example:-
Step 1:
Let's assume
[tex]A=\left ( \begin{matrix}-6 & 9\\ 2& 7\\ 1 & 0\end{matrix} \right )[/tex]3x2 & [tex]B=\left ( \begin{matrix}1\\ -6\\ 7\end{matrix} \right )[/tex]3x1
Since matrix multiplication of matric A and matrix B is only possible,
When the number of columns in A = Number of rows in B.
Step 2:
Let's A as m x n; Here m = rows and n=columns
B as p x q; Here p = rows and q=columns.
When n [tex]\neq[/tex] p, the matrix-vector is not defined.
That is matrix multiplication Ax is not possible.
Hence the matrix is not defined.

Answer:
n= 2x-6y
Step-by-step explanation:
So we might look at this and have an immediate panic attack, but if there is one thing we might look to to help us, it would be logarithms. Logarithms have many wonderful properties that will help us solve this equation. Let's get started:
1. This is the starting equation. [tex](2^{\frac{1}{2} } )^{n} =\frac{2^x}{8^y}[/tex]
2. Let's use the power to power rule on the left and multiply 1/2 by n:
a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]
3. Next, lets take the log of both sides and use the properties of logarithms:
a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]
b. [tex]log(2^{\frac{1}{2}n }) =log(\frac{2^x}{8^y})[/tex]
c. One property we are allowed to use is bringing down the exponent on the left, and another property we can use is when you have the log of a fraction, that is the same thing as the log(numerator)-log(denominator)
d. [tex]\frac{1}{2}n *log(2) =log(2^x)-log(8^y)[/tex]
e. After we do this, we can use the same property of bringing down the exponent on the right side:
f. [tex]\frac{1}{2}n *log(2) =x*log(2)-y*log(8)[/tex]
g. After this, because log(2) and 1/2 are both numbers and are multiplied by n, we can divide them from both sides, and simplify:
h. [tex]\frac{1}{2}n =\frac{x*log(2)-y*log(8)}{log(2)}[/tex]
i. [tex]2(\frac{1}{2})n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]
j. [tex]n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]
k. After this, we must simplify the fraction because log(2)/log(2)=1, and log(8)/log(2)=3, these are both because 2^1=2 and 2^3=8 respectively:
l. [tex]n =2(\frac{x*log(2)}{log(2)}-\frac{y*log(8)}{log(2)} )[/tex]
m. Lastly, let's cancel and distribute:
n. [tex]n =2(x-3y)[/tex]
o. [tex]n=2x-6y[/tex]
Find all of the equilibrium solutions. Enter your answer as a list of ordered pairs (R,W), where R is the number of rabbits and W the number of wolves.

Step-by-step explanation:
Given
See attachment for complete question
Required
Determine the equilibrium solutions
We have:
[tex]\frac{dR}{dt} = 0.09R(1 - 0.00025R) - 0.001RW[/tex]
[tex]\frac{dW}{dt} = -0.02W + 0.00004RW[/tex]
To solve this, we first equate [tex]\frac{dR}{dt}[/tex] and [tex]\frac{dW}{dt}[/tex] to 0.
So, we have:
[tex]0.09R(1 - 0.00025R) - 0.001RW = 0[/tex]
[tex]-0.02W + 0.00004RW = 0[/tex]
Factor out R in [tex]0.09R(1 - 0.00025R) - 0.001RW = 0[/tex]
[tex]R(0.09(1 - 0.00025R) - 0.001W) = 0[/tex]
Split
[tex]R = 0[/tex] or [tex]0.09(1 - 0.00025R) - 0.001W = 0[/tex]
[tex]R = 0[/tex] or [tex]0.09 - 2.25 * 10^{-5}R - 0.001W = 0[/tex]
Factor out W in [tex]-0.02W + 0.00004RW = 0[/tex]
[tex]W(-0.02 + 0.00004R) = 0[/tex]
Split
[tex]W = 0[/tex] or [tex]-0.02 + 0.00004R = 0[/tex]
Solve for R
[tex]-0.02 + 0.00004R = 0[/tex]
[tex]0.00004R = 0.02[/tex]
Make R the subject
[tex]R = \frac{0.02}{0.00004}[/tex]
[tex]R = 500[/tex]
When [tex]R = 500[/tex], we have:
[tex]0.09 - 2.25 * 10^{-5}R - 0.001W = 0[/tex]
[tex]0.09 -2.25 * 10^{-5} * 500 - 0.001W = 0[/tex]
[tex]0.09 -0.01125 - 0.001W = 0[/tex]
[tex]0.07875 - 0.001W = 0[/tex]
Collect like terms
[tex]- 0.001W = -0.07875[/tex]
Solve for W
[tex]W = \frac{-0.07875}{ - 0.001}[/tex]
[tex]W = 78.75[/tex]
[tex]W \approx 79[/tex]
[tex](R,W) \to (500,79)[/tex]
When [tex]W = 0[/tex], we have:
[tex]0.09 - 2.25 * 10^{-5}R - 0.001W = 0[/tex]
[tex]0.09 - 2.25 * 10^{-5}R - 0.001*0 = 0[/tex]
[tex]0.09 - 2.25 * 10^{-5}R = 0[/tex]
Collect like terms
[tex]- 2.25 * 10^{-5}R = -0.09[/tex]
Solve for R
[tex]R = \frac{-0.09}{- 2.25 * 10^{-5}}[/tex]
[tex]R = 4000[/tex]
So, we have:
[tex](R,W) \to (4000,0)[/tex]
When [tex]R =0[/tex], we have:
[tex]-0.02W + 0.00004RW = 0[/tex]
[tex]-0.02W + 0.00004W*0 = 0[/tex]
[tex]-0.02W + 0 = 0[/tex]
[tex]-0.02W = 0[/tex]
[tex]W=0[/tex]
So, we have:
[tex](R,W) \to (0,0)[/tex]
Hence, the points of equilibrium are:
[tex](0,0)[/tex] [tex](4000,0)[/tex] and [tex](500,79)[/tex]

Uniform would most likely be characteristics of the histogram obtain.
What is histogram?A histogram is a rough representation of the distribution of numerical data. The term was first coined by Karl Pearson.
The histogram is the width of the area covered by the x-axis bars. These are approximate values because the histograms show the bin values instead of the original data values.
If a histogram is bell-shaped, it can be modestly described by its center and width. The center is the location of its axis of symmetry. The spread is the distance between the center and one of its inflection points.
