Answer:
slope 3, y intercept 4
Step-by-step explanation:
The y intercept is where it crosses the y axis
It crosses at y=4
The slope is positive since it goes from bottom left to top right
The slope is up 3 over 1 so it is 3/1 = 3
There are about 3.5725 * 10^4 grains of sand in an 8-ounce cup. Based on this, about how many grains of sand would there be in a 5-gallon container (note: 1 gallon = 16 cups). Write the result in scientific notation.
Answer:
[tex]3.5725 * 10^5[/tex]
Step-by-step explanation:
Given
There are about 3.5725 * 10^4 grains of sand in an 8-ounce cup.
Required
How many grains of sand would there be in a 5-gallon container?
Let x represent the number of grains in 5 gallon; So, From the question, we have that;
8 cups = 3.5725 * 10^4
5 gallon = x
Cross Multiply
x * 8 cups = 5 gallon * 3.5725 * 10^4
Recall that 1 gallon = 16 cups
[tex]x * 8\ cups = 5 * 16\ cups * 3.5725 * 10^4[/tex]
[tex]x * 8 = 5 * 16 * 3.5725 * 10^4[/tex]
Divide both sides by 8
[tex]\frac{x * 8}{8} = \frac{5 * 16 * 3.5725 * 10^4}{8}[/tex]
[tex]x = \frac{5 * 16 * 3.5725 * 10^4}{8}[/tex]
[tex]x = 5 * 2 * 3.5725 * 10^4[/tex]
[tex]x = 10 * 3.5725 * 10^4[/tex]
[tex]x = 3.5725 * 10^5[/tex]
Hence, the number of grains of sand in 5 gallon is [tex]3.5725 * 10^5[/tex]

Answer:
t and u are parallel lines
s and t are also parallel lines
Step-by-step explanation:
If two parallel lines are cut by a transversal ,
then in it
pair of alternate angle are equals, similarly vice versa
if pair of alternate angle are equals then lines are parallel
pair of corresponding angles are equal and vice-versa
for example
in the given problem
if line t and u are parallel (note we have assumed this to give example of parallel lines)
then angle 7 and 9 are called alternate angles
pair of angles 5 and 9 are corresponding angles.
________________________________________________
given
∠8 = ∠10 which are alternate angles for line t and u and s is transversal for it,
thus t and u are parallel lines
___________________________
∠1 = ∠3 as they vertically opposite angles
and we know that pair of vertically opposite angles are equal
given
∠1 = ∠7
thus
∠3 = ∠7
as pair of angles ∠3 and ∠7 are corresponding angles. and are equal and hence line s and t are also parallel.

Answer:
[tex]X = \begin{bmatrix}1&3\\ 2&4\end{bmatrix}[/tex]
Step-by-step explanation:
The question we have at hand is, in other words,
[tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}\left(X\right)=\begin{bmatrix}8&20\\ \:3&7\end{bmatrix}[/tex] - where we have to solve for the value of [tex]X[/tex]
If we have to isolate [tex]X[/tex] here, then we would have to take the inverse of the following matrix ...
[tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}[/tex] ... so that it should be as follows ... [tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}^{-1}[/tex]
Therefore, we can conclude that the equation as to solve for " [tex]X[/tex] " will be the following,
[tex]X=\begin{bmatrix}4&2\\ 1&1\end{bmatrix}^{-1}\begin{bmatrix}8&20\\ 3&7\end{bmatrix}[/tex] - First find the 2 x 2 matrix inverse of the first portion,
[tex]\begin{bmatrix}4&2\\ 1&1\end{bmatrix}^{-1}[/tex] = [tex]\frac{1}{\det \begin{pmatrix}4&2\\ 1&1\end{pmatrix}}\begin{pmatrix}1&-2\\ -1&4\end{pmatrix}[/tex]= [tex]\frac{1}{2}\begin{bmatrix}1&-2\\ -1&4\end{bmatrix}[/tex] = [tex]\begin{bmatrix}\frac{1}{2}&-1\\ -\frac{1}{2}&2\end{bmatrix}[/tex]
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
[tex]X = \begin{bmatrix}\frac{1}{2}&-1\\ -\frac{1}{2}&2\end{bmatrix}\begin{bmatrix}8&20\\ 3&7\end{bmatrix}[/tex] ,
[tex]X = \begin{pmatrix}\frac{1}{2}\cdot \:8+\left(-1\right)\cdot \:3&\frac{1}{2}\cdot \:20+\left(-1\right)\cdot \:7\\ \left(-\frac{1}{2}\right)\cdot \:8+2\cdot \:3&\left(-\frac{1}{2}\right)\cdot \:20+2\cdot \:7\end{pmatrix}[/tex] - Simplifying this, we should get ...
[tex]\begin{bmatrix}1&3\\ 2&4\end{bmatrix}[/tex] ... which is our solution.

Step-by-step explanation:
Mean: sum of numbers ÷ how many numbers there are
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.83333
Median: middle number
3 3 4 5 5 9
4 + 5 = 9
9 ÷ 2 = 4.5
4.83333 > 4.5 so the mean is greater than the median.

Find the number of 4-digit numbers that contain at least three even digits.
Answer:
4625 numbers
Step-by-step explanation:
To solve this problem we can separate it in different cases, and then we sum the amount of numbers of each case to find our final result.
The first case is: all four numbers are even.
We have 5 even digits, and the first digit of the 4-digit number can't be zero, so for the first digit we have 4 possible values, and for the other 3 digits we have 5 possible values, then the amount of numbers with this condition is:
[tex]N_1 = 4 * 5 * 5 * 5 = 500\ numbers[/tex]
The second case is the number having three even digits and one odd digit, and the first digit is the odd digit.
In this case, the first digit has 9 possible values (all digits but zero) and the other 3 digits have 5 possible values (even digits):
[tex]N_2 = 9 * 5 * 5 * 5 = 1125\ numbers[/tex]
The third case is the number having three even digits and one odd digit, and the first digit is not the odd digit.
In this case, the first digit has 4 possible values, the odd digit has 10 possible values and the other two digits have 5 possible values. The odd digit can be the second, the third or the fourth digit, so we multiply our result by 3 (because we will find the same result if we choose the odd digit to be the second, third or fourth):
[tex]N_3 = 3 * 4 * 10 * 5 * 5 = 3000\ numbers[/tex]
So the final result is the sum of these cases:
[tex]N = N_1 + N_2 + N_3[/tex]
[tex]N = 500 + 1125 + 3000 = 4625\ numbers[/tex]

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
There are two figures one is cone and other is Cylinder.
The volume of cone can be find by using πr²h/3
r=5, h=6
Volume = π(25)(6)/3
=50π
Now to find volume of cylinder.
h=50 and r=1
Volume = πr²h
=50π
the volumes are same for both cylinder and cone.
Hence, the volume of cone and cylinder are same or equal, so they are equal is correct.

Consider the system of equations given in slope-intercept form. y = −13x + 17, y = 5x - 23 The solution seems to be about (8, 14). Use the graphing calculator to find the exact values for the intersection point. What is the solution to this system of equations?
The exact values for the intersection point is (20/9, -107/9)
Given the system of equation expressed as;
y = −13x + 17;
y = 5x - 23
Since they are both y-values, we will equate both expressions to have:
-13x + 17 = 5x - 23
-13x - 5x = -23 - 17
-18x = -40
x = 40/18
x = 20/9
Substitute x = 20/9 into equation 2:
y = 5x - 23
y = 5(20/9) - 23
y = 100/9 - 23
y = -107/9
Hence the exact values for the intersection point is (20/9, -107/9)

Answer:
(3/2, 0+), (-1, 0+)
Step-by-step explanation:
An exact "zero" of a polynomial is characterized by a point on the x-axis. In this case the best approximation to that is the point (3/2, 0+); the next best approximation is (-1, 0+). Note that neither of these two points actually lies on the x-axis, but that both are closer to the x-axis than are any of the other given points.
The x-values which best approximate roots of the polynomial are x=1.1 and x=4.1
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
The roots of any polynomial can easily be determined by the graph. To find the roots from the graph, we just have to see the values of x, for which the value of whole polynomial becomes 0.
We can see in the graph that there are three points where the value of polynomial becomes 0.
The roots of a polynomial occur where the graph crosses the x-axis
x=1.1
x=4.1
Hence, the x-values which best approximate roots of the polynomial are x=1.1 and x=4.1

Suppose that a line segment is translated. Which of the following is true?
The line segment's position and length change.
The line segment's position changes, but its length remains the same.
The line segment's slope changes, but its length remains the same.
The line segment's length and position remain the same.
Answer:
The line segment's position changes, but its length remains the same.
Step-by-step explanation:
When a line segment is translated, it only will move its position up, down, or to the side.
The slope and length will stay the same, but the position will change.
So, this answer is correct because the position changes but not the length.
