Answer:
0
Step-by-step explanation:
The y-coordinates of the points are the same, so it is a horizontal line with a slope of 0.
___
slope = (change in y)/(change in x) = (4 -4)/(-5-(-1)) = 0/-4 = 0
ANSWER
0
EXPLANATION
The slope of a straight line is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
The given line passes through (-1,4) and (-5,4).
We substitute the points into the formula to get:
[tex]m = \frac{4 - 4}{ - 5 - - 1} [/tex]
[tex]m = \frac{4 - 4}{ - 5 + 1} [/tex]
This simplifies to:
[tex]m = \frac{0}{ - 4} [/tex]
Zero divided by any number is zero.
Therefore, the slope is:
[tex]m = 0[/tex]
In Galveston, Texas there is a beautiful attraction called the Rainforest Pyramid which contains man plants and a variety of rainforest animals. The builders needed to calculate the volume of the squar pyramid to plan the climate control system. The length of the base is approximately 69.6 yards and the height is 33 yards. Which of the following is the closest estimate of the volume?
Answer:
53,286 yards
Step-by-step explanation:
69.6x69.6x33/3
The volume of the square pyramid is [tex]53,286[/tex] yards.
What is volume of the square pyramid?
The volume of a square pyramid is one-third of the product of the area of the base and the height of the pyramid.
[tex]V=\frac{1}{3} b^{2} h[/tex]
From the given,
The length of the base [tex]b[/tex] is [tex]$69.6\,\text{yards}$[/tex].
Height [tex]h[/tex] is, [tex]$33\,\text{yards}$[/tex].
We have to find [tex]V[/tex].
So,
[tex]$V=\frac{1}{3}{{\left( 69.6 \right)}^{2}}\cdot 33$[/tex]
[tex]$\therefore V=53286$[/tex]
Hence, the volume of the square pyramid is [tex]53,286[/tex] yards.

Which equation when graphed has X-intercepts at (8,0) and (-2, 0) and a y-intercept at (0-48)?
Answer:
[tex]y=3x^{2}-18x-48[/tex]
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to
[tex]y=a(x-x1)(x-x2)[/tex]
where
a is a coefficient
x1 an x2 are the roots or x-intercepts
In this problem we have
[tex]x1=8,x2=-2[/tex]
substitute
[tex]y=a(x-8)(x+2)[/tex]
with the y-intercept (0,-48) find the value of a
substitute
[tex]-48=a(0-8)(0+2)[/tex]
[tex]-48=-16a[/tex]
[tex]a=3[/tex]
The equation is equal to
[tex]y=3(x-8)(x+2)\\ \\y=3(x^{2}+2x-8x-16)\\ \\ y=3(x^{2} -6x-16)\\ \\y=3x^{2}-18x-48[/tex]

Using distributive property, which of the following expressions is equivalent to 6(3 + 6 y)?
A. 9 + 6Y
B. 18 + 6 y
C. 9 + 12y
D. 18 + 36y
Answer:
D. 18+36y
Step-by-step explanation:
Because you would simply multiply each of the numbers in the parenthesis by the number outside, to get D.
Answer:
D. 18 + 36y
Step-by-step explanation:
Distributive property
The multiplication of a number by a sum is equal to the sum of the multiplications of that number for each of the addends.
6(3 + 6y) = (6)(3) + (6)(6y)= 18 + 36y
identify the period of the graph
ANSWER
The period is 4π
EXPLANATION
The period refers to the interval on which the graph completes one full cycle.
In other words, it is the interval on which the graph repeats itself.
From the graph, the function repeats itself after every 4π units.
Therefore the period is 4π
find the range
3, -9, 7, -1, 5, -4, 2
Answer:
16
Step-by-step explanation:
to find the range, you have to subtract the smallest number from the biggest number.
In this case 7-(-9)
7-(-9)=16
range=16
Answer:
16
Step-by-step explanation:
The range is the difference between the greatest number and the least number.
The greatest number here is 7.
The least number here is -9
Now, Subtract the least number from the greatest number:
7 - (-9) = 16
Hence the range is 16.
The areas of the square and the rectangle are equal.
What is the value of x?
Answer:
x=12
Step-by-step explanation:
Area of the square
A = x^2
Area of the rectangle
A = (2x-8) (x-3)
Foil
A = 2x^2 -6x -8x +24
= 2x^2 -14x+24
The areas are equal
x^2 = 2x^2 -14x+24
Subtract x^2 from each side
x^2 - x^2 = 2x^2-x^2 -14x+24
0 = x^2 -14x -24
Factor
0 = (x-12) (x-2)
Using the xero product property
x-12= 0 x-2 =0
x=12 x=2
But looking at the rectangle
x-3 is a side length
2-3 is negative so x cannot equal 2
x=12

Imagine that you are an elementary-school math teacher. You need to develop a lesson plan for teaching measurement and will be using items such as rulers and three-dimensional geometric shapes. Describe the strategies you will use to adjust instruction to include a student who has a visual disability
I don’t see what you trying to explain
When teaching measurement to a student with a visual disability, use tactile materials, auditory cues, non-visual measurement tools, real-world examples, and encourage peer collaboration.
Explanation:When teaching measurement to a student with a visual disability, it is important to use alternative methods of instruction that focus on touch and auditory experiences. Here are some strategies you can use:
Provide tactile materials: Allow the student to explore three-dimensional geometric shapes with their hands. You can use manipulatives or 3D models to enhance their understanding.Use auditory cues: Describe the measurements using clear and precise language. For example, instead of saying 'This object is 5 centimeters long', say 'This object is as long as five paperclips.' This helps the student form a mental image.Include non-visual measurement tools: Utilize tools like braille rulers, talking calculators, or measuring tapes with tactile markings. This allows the student to independently measure objects.Provide real-world examples: Relate measurements to everyday situations. For example, you can discuss the length of a classroom desk or the volume of a water bottle. This helps the student connect measurement concepts to their own experiences.Encourage peer collaboration: Pair the student with a sighted buddy who can assist them during hands-on activities. This promotes inclusive learning and allows the student to engage with their peers.Learn more about How to adjust instruction for a student with a visual disability in math measurement lessons here:https://brainly.com/question/39515127

A city has a population of 390,000 people. Suppose that each year the population grows by 8.75%. What will the population be after 12 years?
After 12 years, the population will be approximately 993,993 people.
The city's current population is 390,000 and it grows at a rate of 8.75% each year. To find the population after 12 years, we use the formula for exponential growth:
P(t) = P° × (1 + r)t
Where:
P(t) is the future populationP° is the initial populationr is the annual growth rate (expressed as a decimal)t is the number of yearsFirst, convert the growth rate to decimal form:
8.75% = 0.0875
Next, apply the exponential growth formula:
P(12) = 390,000 × [tex](1 + 0.0875)^{12}[/tex]
P(12) = 390,000 × [tex]( 0.08750)^{2}[/tex]
Using a calculator, we get:
P(12) = 390,000 × 2.5487
P(12) = 993,993
What is the area of the gray triangle shown?
Answer:
The area of the triangle is basically half the area of the square, so we only need to find the area of the square and divide it by 2:
S = (15 · 15)/2 = 112.5 (square units)
Answer:
112.5 square units
Step-by-step explanation:
Area = 1/2bh
where b = 15 and h = 15 (you can look at the graph)
So A = 1/2(15)(15) = 225/2 = 112.5 square units
Answer
112.5 square units
The Sun is v kilometers from the upper edge of the Earth's atmosphere and q kilometers from the surface of the Earth.
Which of the following expressions always represents the distance between the Earth’s surface and the upper edge of the Earth's atmosphere?
Answer:
q - v
Step-by-step explanation:
v = distance between Sun and atmosphere
q = distance between Sun and surface of Earth
So the distance between the atmosphere and the surface of the earth is the difference between them. Since q > v:
d = q - v
Can 5, 6 and 30 squared form a right triangle?
Answer:
no
Step-by-step explanation:
A triangle is equal to 180.
5²+6²=30²
25+36=900
61=900
No solution
Answer:
No; it cannot form a right triangle
Step-by-step explanation:
Use the Pythagorean theorem.
5 squared + 6 squared ≠ 30 squared
25 + 36 ≠ 90000
61 ≠ 90000
Also, note that that the sum of the two shorter lengths have to be greater than the longer length to form any kind of triangle.

The Lin family bought a dozen bagels. They ate 1/4 of the bagels today and 5/12 of the bagels yesterday. What fraction of the bagels did they eat in all? Explain how you found your answer.
Answer:
2/3
Step-by-step explanation:
To be able to find what the total fraction of bagels eaten, the fractions need to have common denominators. To do this, you multiply 1/4 by 3 in both the numerator and the denominator. Now that the two fractions have the same denominator, you can add the fraction's numerator to get the total fraction, 8/12. However, 8/12 can be simplified more, so you divide by 4 and end up with 2/3.
