Answer:
First option
Step-by-step explanation:
There is a mistake in the description of the first function.
On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).
Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:
Rate of change: (y2 - y1)/(x2 - x1)
Points of the 1st graph: (-4, 1), (0, 3).
Rate of change: (3- 1)/(0 - (-4)) = 1/2
Points of the 2nd graph: (-4, 1), (0, -3).
Rate of change: (-3 - 1)/(0 - (-4)) = -1
Points of the 3rd graph: (-4, 0), (0, 4).
Rate of change: (4 - 0)/(0 - (-4)) = 1
Points of the 4th graph: (-4, 0.25), (0, 4).
Rate of change: (4 - 0.25)/(0 - (-4)) = 0.9375

Answer:
D) slope of function A is -2, function B is 4
Step-by-step explanation:
you can see from the equation, y=-2x+1, that the slope (or rate of change) is -2 because it is the coefficient of the 'x' term
to get the slope of Function B we can use the slope formula:
slope = \(\frac{(y-y)}{(x-x)}\)
using points (1,1) and (3,9) we get:
slope = (9-1)/(3-1)

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

Here is an example of how to draw an isosceles trapezoid:
_______
/ \
/_________\
In this trapezoid, the two parallel sides (the top and bottom sides) are of equal length, and the two non-parallel sides (the left and right sides) are also of equal length. The angles between the top and left sides and between the top and right sides are equal, as are the angles between the bottom and left sides and between the bottom and right sides.
What is an isosceles trapezoid?An isosceles trapezoid is a type of trapezoid where the two non-parallel sides of the trapezoid are of equal length. This means that the trapezoid has a line of symmetry through its mid-point, which divides the trapezoid into two congruent triangles. The two parallel sides of an isosceles trapezoid are also referred to as bases, and the height of the trapezoid is the perpendicular distance between the two bases.
Because an isosceles trapezoid has two congruent triangles, the angles opposite these sides are also congruent. Therefore, an isosceles trapezoid has two pairs of congruent angles, with each pair containing one acute angle and one obtuse angle. The acute angles are located adjacent to the parallel sides, while the obtuse angles are located adjacent to the non-parallel sides.
Isosceles trapezoids have several interesting properties, including that the diagonals of an isosceles trapezoid are congruent, and that the diagonals bisect each other. Additionally, the length of each diagonal can be found using the Pythagorean theorem, and the area of an isosceles trapezoid can be determined using the formula:
Area = ((a + b) / 2) * h
Where "a" and "b" are the lengths of the two parallel sides (bases) and "h" is the height of the trapezoid.
PART B:
An isosceles trapezoid is a quadrilateral with two parallel sides (the bases) and two non-parallel sides of equal length. A parallelogram is also a quadrilateral with two pairs of parallel sides.
An isosceles trapezoid can be thought of as a special case of a parallelogram where one pair of opposite sides is shorter than the other pair. In fact, if you extend the non-parallel sides of an isosceles trapezoid until they intersect, you will get a parallelogram with the same base and height as the original trapezoid.
Conversely, if you take a parallelogram and draw a line segment parallel to one pair of opposite sides, you will get an isosceles trapezoid. This means that every isosceles trapezoid can be thought of as a parallelogram with a missing piece, and every parallelogram can be thought of as an isosceles trapezoid with extra pieces added on.
So, in summary, isosceles trapezoids and parallelograms are related in that isosceles trapezoids can be thought of as special cases of parallelograms, and parallelograms can be thought of as isosceles trapezoids with extra pieces added on.
PART C:
No, we cannot use the term "isosceles" to describe a rectangle because a rectangle, by definition, has four right angles and opposite sides that are parallel and congruent to each other. An isosceles trapezoid, on the other hand, has only one pair of parallel sides and two non-parallel sides that are congruent to each other.
The term "isosceles" is typically used to describe triangles or trapezoids where two sides are congruent to each other. In an isosceles triangle, two sides are equal in length, while in an isosceles trapezoid, two non-parallel sides are equal in length. However, in a rectangle, all four sides are equal in length, not just two.
Therefore, while we can describe a rectangle as having all sides congruent to each other, we cannot describe it as an isosceles rectangle because "isosceles" implies only two sides are congruent, which is not the case for a rectangle.

A right triangle has a leg length of 10 meters and a hypotenuse that is 26 meters. What is the length of the other leg?
Answer:
The length of the other leg is 24 meters.
Step-by-step explanation:
Well, let's think about the equation that gives us the hypotenuse in the first place, the Pythagorean theorem (which only works on right triangles!).
\(a^2+b^2=c^2\)
The a^2 is one side of the triangle that we know and the b^2 is the other, the c^2 is the hypotenuse we are trying to solve.
Seeing that in this question, we can put 10, in the place of a^2, and 26 in the place of c^2
\(10^2+b^2=26^2\)
That's what we have down the information we have, but now we'll have to do some rearranging to solve for the other leg's length. First let's square the numbers, 10^2 = 100 and 26^2= 676!
\(100+b^2=676\)
Now we need to get b^2 by itself so we can solve it! Let's subtract 100 from both sides to do so,
\(100-100+b^2=676-100\)
\(b^2=676-100\)
\(b^2=576\)
Now we got b^2 = 576!
But that's not our answer we have to square root it to get rid of the squared part!
\(\sqrt{b^2} = \sqrt{576}\)
and when we do that we get,
\(b=24\)
The length of the other leg is 24 meters!
The length of the other leg is 24 m.
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
A right triangle has a leg length of 10 meters and a hypotenuse that is
26 meters.
The length of the other leg = x
We will apply the Pythagorean theorem.
x² + 10² = 26²
x² + 100 = 676
x² = 676 - 100
x² = 576
x = 24
Thus,
The length of the other leg is 24 m.

Answer:
Part A:
6 feet
Part B:
Around 9.17 feet
Part C:
Around 3 feet
Step-by-step explanation:
Part A:
The Pythagorean Theorem (which is a^2 + b^2 = c^2), is the simpilist way to solve this. a = 8; c = 10. so, the problem becomes (64 + b^2 = 100). Subtract 64 from both sides to get (b^2 = 36). Square root both sides to get (b = 6).
Part B:
Using the same method, but with different measurements:
(a^2 + b^2 = c^2)
(16 + b^2 = 100)
(b^2 = 84)
(b = 9.17)
Part C:
The difference of 9.17 and 6 is 3.17. Therefore, the closest foot is 3. Hope this helps! Have a great day! :)
