1+1+1-5+2+2+2+4-8 x 100 +1
Answer:
-792
Step-by-step explanation:
According to PEMDAS, you would multiply 8 x 100 first making the equation
1+1+1-5+2+2+2+4-800+1
then combine like terms, 8-800+1
Since 8 is smaller than 800, you would get a negative number, -792
then you add 1, making your answer -792
If the figure below is translated in the direction described by the arrow, what will be the new coordinates of point D after the transformation?
The new coordinates of point D after the transformation(-4 -4)
How can new coordinates be found after translation?If the following figure is translated in the manner given, then - 1By adding the value of the horizontal translation to the initial x-coordinate (adding a negative amount if translating to the left), one may get the new x-coordinate of the moved point.A point moves along the x-axis when it is translated to the right or left, changing its x-coordinate. As a result, if a point is moved one unit to the right, its x-coordinate rises by one unit, changing the value of the point (x,y) to (x+a,y).The new coordinates of point D after the transformation (-4 -4).To learn more about coordinates refer to:

If the social security tax is 6.2% and the Medicare tax is 1.45% and Murr annual salary is 57,285.50 then what is murrs annual social security deduction
Answer: Murr's annual social security deduction is the amount of money he pays in social security taxes. Social security tax is 6.2% of Murr's annual salary. To find the annual social security deduction, we can multiply Murr's annual salary by the social security tax rate:
57,285.50 x 6.2% = 3,541.829
Murr's annual social security deduction is 3,541.829
Note that Medicare tax is 1.45% and it's calculated separately, if you want to calculate it you can use the same formula:
57,285.50 x 1.45% = 829.4078
So the total Social security and Medicare tax is 3,541.829 + 829.4078 = 4,371.2368
It's important to note that these are the federal Social Security and Medicare taxes, there might be additional state taxes or deductions that are not included.

Which rule represents the relationship in the table above?
Oy=x
Oy = 2.54x
Oy=x+1.54
Oy=x²
The rule that is used for the relationship in the table is
B. y = 2.54xHow to find the rule as used for the tableThe relationship between x in inches and y in centimeters as represented can be solved by directly on the table or using the knowledge of conversion of inches to centimeter
Another procedure to solve this is to try the equations as in the options;
The first option is y = x, this is obviously wrong as the values in the y and the values in the x are not equal.
The second option, is y = 2.54x
for x = 1, y = 2.54 * 1 = 1
for x = 2, y = 2.54 * 2 = 5.08
and continuing for other values shows that this is the correct option

For the subspace below, (a) find a basis for the subspace, and (b) state the dimension. {[ 6a-2c -5b-5c -6a+ 5b+ 2c -6a+ 2c]:a b c in R]
(a) A basis for a subspace is a set of linearly independent vectors that span the subspace. To find a basis for this subspace, we can use the following steps:
Write the given set of vectors as the rows of a matrix, with each vector as a row.
Use row-reduction (Gaussian elimination) to put the matrix in row-echelon form.
The non-zero rows of the row-echelon form matrix form a basis for the subspace.
So, we get the matrix:
| 6a - 2c | -5b - 5c | -6a + 5b + 2c | -6a + 2c |
Using row-reduction, we can simplify the matrix to:
| 1 - 1/3 | 0 | 1/3 | -1/3 |
The non-zero rows are {[ 1 - 1/3 0 1/3 -1/3 ]}
So, a basis for the subspace is:
{[ 1 - 1/3 0 1/3 -1/3 ]}
(b) The dimension of a subspace is the number of linearly independent vectors in a basis for the subspace. In this case, the basis for the subspace has only one vector, so the dimension of the subspace is 1.

need working out
Answer:
a = 6 , b = 17
Step-by-step explanation:
using Pythagoras' identity.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
using right triangle ABD , then
a² + 8² = 10²
a² + 64 = 100 ( subtract 64 from both sides )
a² = 36 ( take square root of both sides )
a = [tex]\sqrt{36}[/tex] = 6
using right triangle ABC
note that BC = a + 9 = 6 + 9 = 15
b² = 8² + 15² = 64 + 225 = 289 ( take square root of both sides )
b = [tex]\sqrt{289}[/tex] = 17

How to find greatest common factor of 5x²a + 5xa²?To find the greatest common factor (GCF) of the expression 5x²a + 5xa², we need to find the greatest term that can divide into both terms in the expression.
In this case, the GCF is 5xa, as it can divide into both 5x²a and 5xa².
We can check this by dividing both terms with 5xa:
5x²a + 5xa² = (5xa)(x) + (5xa)(a) = 5xa (x + a)

b) The Seattle Sea hawks, the observed number of wins (10) is 4.12 less than the predicted number of wins based on the least-squares regression line.
c) It will increase the R-Sq and R-Sq(adj) and decrease the S.
What is the equation of least-squares regression and calculation for above answer?The equation of the least-squares regression line is given by:
Number of wins = 25.66 - 0.003131 * (Yards_allowed)
This equation shows the relationship between the number of wins for a team (the dependent variable) and the number of yards allowed by the team (the independent variable).
The slope of the line is -0.003131, which means that for every 1 yard increase in yards allowed, the number of wins decreases by 0.003131. The y-intercept of the line is 25.66, which represents the predicted number of wins when yards allowed is 0.
b) To calculate the residual for the Seattle Seahawks, we can use the equation of the least-squares regression line and the data for the team:
Residual = Observed value - Predicted value
Residual = 10 - (25.66 - 0.003131 * 4668)
Residual = 10 - (25.66 - 14.12)
Residual = -4.12
This means that for the Seattle Seahawks, the observed number of wins (10) is 4.12 less than the predicted number of wins based on the least-squares regression line.
c) The point representing the Carolina Panthers (5167 yards allowed, 15 wins) has a positive effect on the equation of the least-squares regression line because it is above the line.
This means that the team performed better than expected based on the number of yards allowed. Since this point is an outlier, it will increase the R-Sq and R-Sq(adj) and decrease the S.
