Answer:
Step-by-step explanation:
Sum = -14
Product = - 32
So, the factors = -16 , 2
When we add -16 +2 = -12 and when we multiply it is -32
w⁴ - 14w² - 32 = w⁴ - 16w² + 2w² - 16 * 2
= w²(w² - 16) + 2(w² - 16)
= (w² - 16)(w² + 2)
= (w² - 4²)(w² + 2)
= (w + 4)(w - 4)(w² + 2)
Step-by-step explanation:
Replace w^2 with any other variable for eg: w^2=a
so that will make the equation:
a^2-14a-32
now factorize this equation and u can find the value of a
a^2-16a+2a-32
a(a-16)+2(a-16)
so factors= (a+2) (a-16)
since a was w^2 so replace them with w^2 and u got factors of the equation
you can also directly factorize the whole equation through middle term breaking
w^4-16w^2+2w^2-32
w^2(w^2-16)+2(w^2-16)
(w^2+2)(w^2-16)
you get the same answer

Slightly faster automatically means greater than because it tells you that it it more that the given amount :)
The answer is H and not G because you are subrtracting from the total amount of the walk not adding more distance.

While performing a vertical line test on a graph, you notice that the graph intercepts the vertical line twice. Which of the following correctly interprets the result of the test? (1 point) Because the vertical line intercepted the graph exactly twice, the graph is of a function. Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function. Because the vertical line did intercept the graph exactly twice, the graph is a function and a relation. Because the vertical line intercepted the graph more than once, the graph is of a function, but it is not a relation.
Answers
Answer:
The correct option is;
Because the vertical line intercept the the graph more than once, the graph is of a relation but it is not a function
Step-by-step explanation:
A function is a kind of relation that maps a given set of inputs unto a set of outputs such that each of the values of the input can be linked to only one value of the output, such that the input and outputs form a set of ordered pairs
Therefore, a relation which maps a given input to more than one output is not a function, as such, given that the line intercepts the vertical line twice, then for a given value of x, which is the input, there are more than one value of y, which is the output, as such the relation is not a function.

Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours. What is the mean absolute deviation for the number of hours students practiced the violin? Round to the nearest tenth. 6. 4 6. 8 32 47.
Answers
The mean absolute deviation for the number of hours students practiced the violin is 6.4.
What is the mean absolute deviation?
The average absolute deviation of the collected data set is the average of absolute deviations from a center point of the data set.
Given
Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours.
The given data set is;
45, 38, 52, 58, 42
Mean Deviation = Σ|x − μ|/N.
μ = mean, and N = total number of values
|x − μ| = |45 − 47| = 2
|38− 47| = 9
|52− 47| = 5
|58− 47| = 11
|42− 47| = 5
The mean absolute deviation for the number of hours students practiced the violin is;
[tex]\rm Mean =\dfrac{2+9+5+11+5}{5}\\\\Mean=\dfrac{32}{5}\\\\Mean = 6.4[/tex]
Hence, the mean absolute deviation for the number of hours students practiced the violin is 6.4.

y = x + [ ]
Answers
The Equation of line is y = -x + 3.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Take the points (4, -1) and (0, 3).
so, the slope of line is
m = (3+ 1)/ (0-4)
m = 4/ (-4)
m = -1
So, the equation of line
y= mx+ b
y= -x + b
and, 3 = b
So, the required equation is y = -x + 3.

Which equation represents each dimension of the larger triangle, y, based on the corresponding dimension of the smaller triangle, x?
Y= 2/3x
Y= 3x
Y= 1/3x
Y= 3/2x
How can you use the given side lengths of the triangles to check if your equation is correct?
Answers
Answer:
(b) y = 3x; check using dimensions from the figure
Step-by-step explanation:
The dimensions in the larger triangle are more than the dimensions in the smaller triangle. That means the smaller dimensions need to be multiplied by a value greater than 1 to get the larger dimension. (This eliminates the 1st and 3rd choices.)
__
EquationThe figures are drawn approximately to scale, so it is easy to see that the larger triangle's dimensions are more than double (2 times) those of the smaller triangle. (This eliminates the 4th choice. 3/2 < 2)
The equation that represents the larger dimensions in terms of the smaller ones is ...
y = 3x
__
CheckYou can check this by choosing a smaller dimension and using that in the equation:
bottom leg = 3 in
larger bottom leg = y = 3(3 in) = 9 in . . . . matches the diagram
