Describe the effect of a dilation on the length of a line segment.
The scale factor determines whether line segment dilation is longer or shorter.
What is dilation?Dilation is a transformation that allows you to resize an object. Dilation is a technique for making objects larger or smaller. This transformation yields an image that is identical to the original shape. However, there is a size difference in the shape.The effect of dilation on the length of a line segment:
A line segment dilation is longer or shorter in the ratio given by the scale factor. If the scale factor is greater than one (k > 1), the image will be larger than the pre-image, making the image's segments (sides) longer than the pre-corresponding image's sides (an enlargement).Therefore, a line segment dilation is longer or shorter in the ratio given by the scale factor.

what does SAS stand for? what does it have to do with similar triangles?
Answer: SAS stands for side angle side and it means triangles are congruent by having the same side, angle, and side
Explanation: Let's say, two triangles both have the same angle, say 90 degrees. They also share two side lengths. Both triangles have a side length of 9 and another side length of 8.
The two triangles, sharing all these properties, must be congruent. This congruency is proven by SAS.
However, you must not get confused with other ways to prove congruency like ASA (Angle-Side-Angle)

Use an explicit formula to find the 10 th term of each geometric sequence. 5,10,20,40, . . .
10th term of the geometric sequence = 2560
The explicit formula for the geometric sequence is
[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]
Where
r = common ratio
a = first number of the series
n = number of terms in the series
Common ratio (r) = 10/5 = 20/10 = 2
Here we have to find the 10th term of the series
[tex]a_{10}[/tex] = 5× [tex]2^{10-1}[/tex]

A die is rolled. Find the probability of the outcome. P( greater than 1 )
The probability of getting a number greater than 1 is 5/6
What is the formula of Probability?
The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.
Probability of event happen P(E) = Number of favourable outcomes / Total number of outcomes.
The possible outcomes when a die thrown is {1, 2, 3, 4, 5, 6}. Therefore, the number of possible outcomes of a die is 6.
Now, the numbers greater than 1 between 1 to 6 are P{2, 3, 4, 5, 6} then the number of favourable outcome is 5.
Therefore, probability P of getting a number greater than 1 is:
P = 5/6

What is equation of a straight line?Equation of a straight line is the equation of the form
y = mx + c
y and x are the unknown variables
m is the slope
c is the intercept in the y axis
The equation given in the problem is a special type which is a vertical line
How to write the equation of a vertical lineA vertical line has no intercept on the y axis hence c =0/ This reduces the equation of a straight line to
y = mx + c
at c = 0 we have:
y = mx + 0
y = mx
The slope of the vertical line is undefined. From first principles we have that slope is
m = change in y / change in x
for a line to be vertical the change in x is at the lowest absolute value and the smallest absolute number is zero. note negative number is not inclusive.
Therefore the slope at change in x = 0 represents a vertical line which is
m = change in y / change in x
m = change in y / 0
m = undefined
so y = undefined
check using calculator any number divided by zero gives error which is defined mathematically to be undefined,
We can conclude that the relationship between y and x from the graph is undefined.

The solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.
According to the given question.
We have an equation 5x/4 - 3/x= 1/4.
As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.
Therefore, the solution of the equation 5x/4 - 3/x= 1/4 for x is given by
5x/4 - 3/x= 1/4
⇒ ( 5x^2 -12) /4x = 1/4
⇒ 5x^2 - 12 = (1/4)4x (multiplying both the sides by 4x)
⇒ 5x^2 - 12 = x
⇒ 5x^2 - x -12 = 0
⇒ x = [tex]\frac{1\pm\sqrt{1+240} }{10}[/tex]
⇒ x = (1+√241)/10 or (1 -√241)/10

Step-by-step explanation:A shift of the graph up, down, left, or right, without changing the shape, size, or dimensions of the graph, is called a translation. Examples: If f (x) = x2 + 2x, the equation if the graph is shifted is 4 units up.4 1-2 ft long and 45 in long which one is shorter
45 inch is shorter in length.
Feet is a unit of measuring length as per the US standard system of measurement and centimeters is the unit of length measurement as per the metric system. Feet is abbreviated as 'ft'.
Inches is another measurement of length . It is a unit used for measuring length, approximately equal to 2.54 centimetres, sometimes shown by the symbol ″
1 feet = 12 inches which means feet is a bigger unit than inch.
So 4 feet 1/2 inch = 54 inches
54 inches is greater than 45 inches,

What is the slope of the line that passes through the points (1, -7) and (−2,−7)?
The slope of the line is 0 since the y-value doesn't change, meaning it is a horizontal line.
Answer:
Slope ⇒ 0
Step-by-step explanation:
The formula to find the slope of a line is:
[tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex]
We can use the given two coordinates of the line to find the slope.
( 1, -7 ) ⇒ ( x₁, y₁ )
( -2, -7 ) ⇒ ( x₂, y₂ )
Let us solve this now.
[tex]m = \frac{y_1-y_2}{x_1-x_2}\\\\m = \frac{-7 -(-7)}{1-(-2)}\\\\m = \frac{0}{3}\\\\m=0[/tex]

The final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is $10,942
What is compound interest ?
A compound interest rate is a rate of interest calculated on both the amount saved and the interest earned on it.
In the given question the expression to calculate amount is given as :
A = Pe^(rt)
where,
P = principle amount that is $10,000
r = rate of interest that is 3%
t = time period that is 3 years
Now, calculating Amount by substituting the above value in the formulae :
A = Pe^(rt)
A = 10000 e^(0.03 x 3)
A = 10000 e^(0.09)
A = 10000 x 1.0942
A = $10,942
Therefore, the final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is $10,942
