Answer:
16.6%
Step-by-step explanation:
First, find the difference between the prices:
$3.95 - $3.45 = $0.50
Then, divide the difference by yesterday's price.
$0.50 ÷ $3.95
≈ 0.166
≈ 16.6%
Answer:
12.7%
Step-by-step explanation:
$3.95 - $3.45 = $.50
$.50 / $3.95 = .127 = 12.7%

1. Which of the following expressions can you factor using the reverse FOIL method? Select all that apply. (A) x²+x-6 (B) x^3 + 3x²+x-2 (C)4x^2 – 2x + 1 (D) x² + 8x + 12
Answers
We need to examine each expression at a time.
(A) x^2 + x - 6
notice the -6 has factors 3 and -2 which could be used to reverse the FOIL method:
x^2 + x - 6 = x^2 + 3 x - 2 x - 6 = x( x + 3) - 2 (x + 3) = (x+ 3) (x - 2)
(B) In this cubic expression we cannot use the reverse FOIL to extract factors.
(C) 4 x^2 - 2 x + 1 We cannot reverse the FOIL property either.
(D) x^2 + 8 x + 12
We notice that 12 has factors 2 and 6 which can be used to factor out this expression as shown below:
x^2 + 2 x + 6 x + 12 = x (x + 2) + 6 (x + 2) = (x + 2) (x + 6)
Therefore we were able to use the reverse of the FOIL property in expressions (A) and (D).

find the endpoint S given R(5,1) and midpoint M(1,4)
Answers
Given:
Point R: (5, 1)
Midpoint M: (1, 4)
Since it's been mentioned that point M is a midpoint. Finding S, the graph should look like this:
Let's determine the translation from point M to R, because the opposite of it will be the translation to get point S.
From Point M to R:
[tex]\text{ }\Delta x\text{ = 5 - 1 = 4 (4 units to the right)}[/tex][tex]\Delta y\text{ = 1 - 4 = -3 (3 units downward)}[/tex]Therefore, getting to the endpoint S, it will have 4 units to the left and 3 units upward.

Slope =
y-intercept = (0,
Answers
Answer:
Solutions below.
Step-by-step explanation:
This question tests on the concept of graph reading.
To find the slope of a line, we have to use the following formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Now, we can pick 2 random points on the line to substitute the values in to find the slope.
We will pick
(0, 3) as (x1, y1)
and
(2,0) as (x2, y2)
Therefore the slope will be:
[tex] \frac{0 - 3}{2 - 0} \\ = \frac{ - 3}{2} \\ = - \frac{3}{2} [/tex]
Now to find the y-intercept, as the name suggests, it is the point where the line intercepts the y-axis (vertical axis) , in this case, it is 3.
The point of this intercept is (0,3).
Answer:
slope = -5/3y-intercept = 3Step-by-step explanation:
You want the slope and the y-intercept of the line shown in the graph.
SlopeThe slope is the ratio of "rise" to "run". It is best found by identifying points on the graph where the line crosses grid intersections. The attachment shows two of those: (0, 3), (3, -2).
You can count grid squares or use the slope formula to find the slope.
slope = rise/run = (y2 -y1)/(x2 -x1)
slope = (-2 -3)/(3 -0)
slope = -5/3
Y-interceptThe y-intercept is the y-value of the point where the line crosses the y-axis. We have already found that to be 3, at one of the points used to find the slope.
y-intercept = 3 . . . . point (0, 3)

At what rate is the area of the square increasing when the area of the square is 9 cm
Answers
The rate at which the area of this square increases when the area of the square is 9 cm is 24 cm²/s.
What is rate of change?The rate of change is a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
How to calculate the area of a square?Mathematically, the area of a square can be calculated by using this formula;
A = s²
Where:
A represents the area of a square.s represents the side length of a square.Next, we would determine the side length of a square by making s the subject of formula as follows:
A = s²
s = √A
s = √9
s = 3 cm.
By applying chain rule of differentiation, the rate of change (da/dt) in area of this square with respect to time is given by:
dA/dt = 2 × s(t) × ds/dt
dA/dt = 2 × 3 × 4
dA/dt = 24 cm²/s.

After a translation, the figure becomes the red one, with the following points:

(d) The triangles are similar, because each has angles that measure 36°, 62°, and 82°.
Step-by-step explanation:
Given triangle A has angles 36° and 82°, and a figure showing angles related to triangle B, you want to know if the triangles are similar.
SimilarityThe triangles will be similar if the angles of one are congruent to the angles of the other. Between the two triangles, we are given 3 different angle values, so we need to find at least two additional angle values in order to determine if the triangles are similar.
Angle sum theoremThe sum of angles in a triangle is 180°, so the third angle of triangle A will be ...
angle = 180° -36° -82° = 62°
Exterior angleThe exterior angle of triangle B, given as 144°, is the sum of the remote interior angles:
144° = 62° +angle
82° = angle
ComparisonNow, we have the angles of triangle A as 36°, 62°, and 82°. Two of the angles of triangle B are known to be 62° and 82°, matching those of triangle A.
The triangles are similar, because each has angles that measure 36°, 62°, and 82°.

What is defined as the quadratic function?A quadratic function has been one of the following: f(x) = ax² + bx + c, for which a, b, and c are positive integers and an is not equal to zero. A parabola is a curve that represents the graph of the a quadratic function. Parabolas can open up or down, and their "width" or "steepness" can vary, but they all share a basic "U" shape.For the given question;
The football is kicked by the player.
The second kick is modeled by f(x) = -0.051x(x - 50).
Where, f is the height (in yards) and x is the horizontal distance (in yards).
For calculating the distances that the footballs travel before hitting the ground, Put f(x) = 0.
As, the ball will reach the ground the height of ball above ground will be zero, thus f(x) = 0.
f(x) = -0.051x(x - 50) = 0
Simplifying;
-0.051x² + 2.25x = 0
Or, divide wole equation by x.
0.051x = 2.25
x = 50 yards.
Thus, the distances that the footballs travel before hitting the ground is 50 yards.

117 divided by 18. Show the answer as a fraction in lowest terms
Answers
Answer:
Im unsure what your asking but the answer is 6 1/2 in fraction form and 6.5 in decimal form :/
Step-by-step explanation:
math
When 117 is divided by 18 we get 117/18 in fraction form.
To divide 117 by 18, we perform long division.
We start with the first digit of the dividend (1) and divide it by the divisor (18).
Since 18 is larger than 1, the quotient for this step is 0.
We then bring down the next digit (1) and place it next to the previous result.
Again, since 18 is larger than 11, the quotient for this step is 0.
Therefore, the result of dividing 117 by 18 is 0 with a remainder of 117.
In fraction form, this can be expressed as 117/18.

Given the following question:
The principal wants to estimate the percentage of students in the school who play video games, which is a good number of students. Selecting 30 random students and asking them if they play video games can represent the entire school. Asking 30 random students keeps it from being biased for example option B, asking 30 students who take coding classes is biased because they are in one specific class, they do not represent the majority of the school unless the school is a coding school.
The answer is the first option because it is a random sample of people to represent a population of people. This keeps the results from being biased so asking 30 random students is the way to go.

Graph of Linear inequalitiesFrom the question, we are to determine the linear inequality that is represented by the graph
First, we will determine two points on the line
The line in the graph passes through (0, -4) and (3, -3)
Using the equation,
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
(y - -4)/(x - 0) = (-3 - (-4))/(3 - 0)
(y + 4)/x = (-3 + 4)/3
(y + 4)/x = 1/3
y + 4 = 1/3x
y = 1/3x - 4
y = x/3 - 4
