The formula for slope is [tex]\frac{rise}{run} = \frac{y2-y1}{x2-x1}[/tex].
Subtract y1 from y2. (y1= -1, y2 = 3)
3 - -1 = 4
Now subtract x1 from x2. (x1 = 4, x2 = -4)
-4 -4 = -8
Divide the difference between the y coordinates by the difference between the x coordinates.
[tex]\frac{4}{-8}[/tex] or 4 ÷ -8 = -0.5
Answer:The slope between the two points is -0.5.

Benny’s age is currently 200% of his sister Jenny’s age. What percent of Benny’s age will Jenny’s age
be in 4 years?
Jenny's future age would be expressed as ((x+4)/(2x+4))*100 percent of Benny's future age, where x is Jenny's current age.
Explanation:To solve this problem, we first note that Benny is currently 200% of Jenny's age, meaning Benny's age is twice that of Jenny. So let's denote Jenny's current age as x - Benny's age will be 2x.
In 4 years, Jenny's age will be x+4 and Benny's age will be 2x+4. To calculate what percent of Benny's future age will Jenny's future age be, we have to divide Jenny's future age (x+4) by Benny's future age (2x+4) and then multiply by 100 to get the percentage. Therefore, Jenny's age will be ((x+4)/(2x+4))*100 percent of Benny's age.
Since we don't know their real ages, this is the most accurate answer we can provide, expressed as an algebraic equation. In real-life situation with the real ages known this equation would allow to find out what percent of Benny's age will Jenny’s age be in 4 years.

If Jenny's age is x, Benny's age is 2x. In 4 years, Jenny's age will be x+4 and Benny's will be 2x+4. To calculate what percent of Benny's age Jenny's age will be, we can use this formula: ((x+4)/(2x+4)) × 100.
Explanation:Let's start by expressing Benny's age in terms of Jenny's age. If Benny's age is currently 200% of Jenny's age, then mathematically, we can say:
Benny's age = 200% of Jenny's age
B = 2 × x
Now, let's assume Jenny's age is represented as J. So, Benny's age is 2 × x.
If we want to find out what percent of Benny's age Jenny's age will be in 4 years, let's calculate it step by step.
In 4 years, Benny's age will be:
Benny's age in 4 years = Benny's current age + 4
Benny's age in 4 years = 2 × x + 4
Jenny's age in 4 years will be:
Jenny's age in 4 years = Jenny's current age + 4
Jenny's age in 4 years = x + 4
Now, let's find out what percent of Benny's age Jenny's age in 4 years will be:
Percent = (Jenny's age in 4 years / Benny's age in 4 years) × 100
Percent = (x + 4) / (2 × x + 4) × 100
This calculation will give us the percentage of Jenny's age compared to Benny's age in 4 years.

shows the square-based pyramid ABCDE. The side length of the base is 96 m and the pyramid's height is 55 m. O is the centre of the square base, directly below E. M is the midpoint of AD. Use Pythagoras' theorem to find the length EM.
Answer:
EM = 73 m
Step-by-step explanation:
Using the right triangle MOE
with legs MO = 48. EO = 55 and hypotenuse EM
Applying Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
EM² = 48² + 55² = 2304 + 3025 = 5329 ( take the square root of both sides )
EM = [tex]\sqrt{5329}[/tex] = 73

What is the area of the base of the cone below?
Given:
Given that the height of the cone is 12 ft.
The volume of the cone is 90 ft³
We need to determine the area of the base of the cone.
Area of the base of the cone:
The area of the base of the cone can be determined using the formula,
[tex]V=\frac{1}{3} \pi r^2 h[/tex]
where the base area is [tex]A=\pi r^2[/tex]
Substituting the value of A in the above formula, we get,
[tex]V=\frac{1}{3}A h[/tex]
Substituting V = 90 and h = 12, we get;
[tex]90=\frac{1}{3}A (12)[/tex]
[tex]90=4A[/tex]
Dividing both sides by 4, we get;
[tex]22.5 =A[/tex]
Thus, the area of the base of the cone is 22.5 square feet.
Hence, Option c is the correct answer.
Describe and correct the error a student made in finding the average rate of change for f(x)equals0.5xsquared over the interval minus4less than or equalsxless than or equalsminus2.
Answer:
please explain it better.
Step-by-step explanation:
The student needs to use the average rate of change formula correctly. For the function f(x) = 0.5x^2 and the interval [-4, -2], the correct average rate of change is -3.
Explanation:The student is looking to find the average rate of change of the function f(x) = 0.5x^2 over the interval [-4,-2]. The average rate of change of a function over the interval [a, b] is calculated by the formula: (f(b) - f(a)) / (b - a).
For our function and interval this calculates to (f(-2) - f(-4)) / (-2 -(-4)). f(-2) is 0.5(-2)^2 = 2, and f(-4) is 0.5(-4)^2 = 8. Substituting into the formula gives (2 - 8) / (-2 -(-4)) = -6 / 2 = -3. So the correct average rate of change for f(x) = 0.5x^2 over the interval [-4,-2] is -3.

An anemometer is a device used to measure wind speed.
The anemometer shown is attached to the top of a pole.
Support wires are attached to the pole 5 feet above the
ground. Each support wire is 6 feet long. How far from
the base of the pole is each wire attached to the ground?
Answer:
3.32ft
Step-by-step explanation:
The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.
Using Pythagoras Theorem:
Hypotenuse²=Adjacent²+Opposite²
6²=5²+x²
x²=36-25
x²=11
x=√11=3.32 ft.
The wires are attached 3.32 ft from the base of the pole on the ground
Answer:
The question can be answered by using a Pythagoras' Theorem : [tex]c^2=a^2+b^2[/tex] to find the base of the pole to which each wire is attached to the ground.
Step-by-step explanation:
the base of the pole is represented by b.
the height of the pole is represented by a= 5 feet
the length of t he wire is represented by c=5 feet.
Thus, using the Phytagoras Theorem,
c^2=a^2+b^2,
[tex]6^2=5^2+b^2\\36=25+b^2,\\36-25=b^2\\Thus, b^2=11,\\b=\sqrt 11[/tex] or b=3.3.
Thus , each wire i attached by about 3.3 feet to the base of the pole.

Find the volume of the composite solid. Round your answer to the nearest tenth
Answer:
1130.4 cubic meters
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
The composite solid has two cones:
The height of the big cone is: 12 mThe height of the small cone is: 18The radius of the common base of the two cones is: 6 m=> the volume of the big cone is:
V = (1/3)π[tex]r^{2}[/tex]·h = (1/3)*3.14*[tex]6^{2}[/tex]*18 = 678.24 cubic meters
=> the volume of the small cone is:
V = (1/3)π[tex]r^{2}[/tex]·h = (1/3)*3.14*[tex]6^{2}[/tex]*12 = 452.16 cubic meters
=> the volume of the composite solid :
= 678.24 + 452.16
=1130.4 cubic meters
Sharon and Jacob started at the same place. Jacob walked 3 m north and then 4 m west. Sharon walked 5 m south and 12 m east. How far apart are Jacob and Sharon now?
A) 5 m
B) 8 m
C) 13 m
D) 18 m
Answer:
d
Step-by-step explanation:
The correct answer is option C: 13 meters. Jacob and Sharon are approximately 13 meters apart.
To determine how far apart Jacob and Sharon are now, we first need to find their final positions and then calculate the distance between those points.
Step-by-Step Solution
→ Jacob's Movement:
He walked 3 meters north and then 4 meters west.
→ Final position of Jacob: (-4, 3).
Sharon's Movement:
→ She walked 5 meters south and then 12 meters east.
→ Final position of Sharon: (12, -5).
To find the distance between their final positions, we can use the Pythagorean theorem. The distance d between the points (-4, 3) and (12, -5) is calculated as follows:
→ d = √[(12 - (-4))² + (-5 - 3)²]
= √[(12 + 4)² + (-8)²]
= √[(16)² + (8)²]
= √[256 + 64]
= √320
= √(16 × 20)
= 4√20
= 4√(4 × 5)
= 8√5
≈ 13 meters
→ Thus, Jacob and Sharon are approximately 13 meters apart.
