[tex]d = 3 \sqrt{13} [/tex]
EXPLANATION
We use the distance formula to find distance between two points.
[tex]d = \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2} [/tex]
The two points are R(-1, 0) and S(8, 6).
We substitute the points into the formula to get:
[tex]d = \sqrt{(8 - - 1)^2 +(6-0)^2} [/tex]
[tex]d = \sqrt{(9)^2 +(6)^2} [/tex]
[tex]d = \sqrt{81+36} [/tex]
[tex]d = \sqrt{117} [/tex]
[tex]d = 3 \sqrt{13} [/tex]
Therefore the distance between the two points is [tex]3 \sqrt{13} [/tex] units.
Answer:
The distance between these points = 3√13
Step-by-step explanation:
Points to remember
Distance formula
Length of a line segment with end points (x1, y1) and (x2, y2) is given by,
Distance = √[(x2 - x1)² + (y2 - y1)²]
It is given two points R(-1, 0) and S(8, 6)
To find the distance
Here, (x1, y1) = (-1, 0) and (x2, y2) = (8, 6)
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(8 - -1)² + (6 - 0)²]
= √[(8+1)² + (6)²]
=√[(9)² + (6)²]
= √[(81 + 36)]
=√117 = √(3 * 3 * 13)
= 3√13
The distance between these points = 3√13
Which of the following is an outlier in the set of data below? I think it’s 12 but I’m not so sure.
I think the answer might be 2
because
in the data given above all the numbers are between 12-19 they are all bigger than 10
and then there's 2 which is very far from 12 or any other numbers there and it is also less than 10
which makes more sense for it to be an outlier.

Step-by-step explanation:
you find a triangle that has an area of 10 sq ft. the height of the triangle is 10 feet. what is the length of the base of the triangle?
Solution:
Given :
Area of triangle = 10 ft² Height of triangle = 10 ftSo, We have to find the Base of Triangle .
Area of triangle = 1/2*b×h, Where represents
B represent Base H represent HeightStep : Substitute those value in Formula;
Area of triangle = 1/2 × b × h
10 = 1/2 × b × 11
20 = 11 × b
b = 20/11
b = 1.81 ft
Therefore, Base of Triangle is 1.81 ft
Final answer:
To find the base of a triangle with an area of 10 sq ft and a height of 10 ft, use the formula 1/2 × base × height. By rearranging the formula and substituting the known values, the base is calculated to be 2 feet.
Explanation:
The question is asking to find the length of the base of a triangle when the area is 10 square feet and the height is 10 feet. The formula for the area of a triangle is 1/2 × base × height. In this case, we know the area (10 sq ft) and the height (10 ft), and we need to solve for the base.
Inserting the known values into the formula gives us:
Area = 1/2 × base × height
10 = 1/2 × base × 10
To solve for the base, we rearrange the formula:
base = 2 × Area / height
base = 2 × 10 / 10
base = 2 feet
Therefore, the length of the base of the triangle is 2 feet.

Answer:
The red line is g(x)
Step-by-step explanation:
* To solve this problem you must to know some fact about
transformation
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
- A vertical stretching is the stretching of the graph away from
the x-axis
• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each of its y-coordinates by k.
• if k should be negative, the vertical stretch or compress is
followed by a reflection across the x-axis.
* Now lets solve the problem
- g(x) = -1/2f(x + 2)
# x + 2 ⇒ means the graph moved 2 units to the left
# -1/2 ⇒ means the graph has vertical compressed followed
by a reflection across the x-axis, then multiply
each y-coordinate by -1/2
- The graph of f(x) intersects x-axis at point (3 , 0)
∴ The point will be (1 , 0) on g(x)
- The graph of f(x) intersects y-axis at point (0 , -6)
∴ The point will be (-2 , 3) on g(x)
* Look to the graph
# The red line is g(x)
# The blue line is f(x)
- To check your answer
# The equation of f(x) is f(x) = 2x - 6
∵ g(x) = -1/2f(x + 2)
∴ g(x) = -1/2[2(x + 2) - 6] = -1/2[2x + 4 - 6] = -1/2[2x - 2] = -x + 1
* g(x) intersect x-axis at point (1 , 0) and y-axis at point (0 , 1)

Answer:
The answer is 90.
Step-by-step explanation:
Area of the path will be 90 square feet.
How to find the area of the path?The yard is rectangular in shape.In the figure, there are two right angles triangles on two sides of the pathArea of the path = (Area of the rectangular yard) - (Area of two right angled triangles)The width of the path is 3 feet. So, the base of the right angled triangle = (12-3) feet = 9 feet Area of the right angled triangle = base x height/2
= (9 x 30/2) square feet = 135 square feet
Area of the yard = ( length x breadth)= ( 30 x 12) square feet = 360 square feet
Area of the part = {360 - 2(135)} square feet= 90 square feet

suppose that F(x)=x^3 and G(x)=-2x^3
Answer:
A
Step-by-step explanation:
Given a function f(x) = x^2, we can say:
g(x) = -(x^2) is the reflection of f(x) in the x-axish(x) = ax^2 is a vertical stretch if a > 1 and a vertical compression if 0 < a < 1The negative sign in front says that G(x) is flipped over the x-axis with respect to F(x). Also, the 2 in front tells us that it is a vertical stretch of the function F(x), since a > 1.
Hence, answer choice A is right.

Find the limit of the function by using direct substitution. limit as x approaches zero of quantity x squared minus two.
Answer:
[tex]\lim_{x \to 0}\ x^2 -2 = -2[/tex]
Step-by-step explanation:
We have the following limit
[tex]\lim_{x \to 0}\ x^2 -2[/tex]
To solve this limit using direct substitution to substitute the value that tends x into f(x) and simplify.
In this case x tends to zero, then we substitute x = 0 in the function and simplify

Determine if line AB is tangent to the circle
1. If AB is tangent to the circle, then
[tex]18^2=(2\cdot7.2)^2+10.8^2[/tex]
We have
[tex]18^2=324[/tex]
[tex](2\cdot7.2)^2+10.8^2=324[/tex]
so AB is indeed tangent to the circle.
2. The unlabeled leg is another radius of the circle so it has length 8. Then if AB is tangent to the circle,
[tex](10+8)^2=8^2+15^2[/tex]
but we have
[tex](10+8)^2=324[/tex]
[tex]8^2+15^2=289[/tex]

Answer:
THE ANSWER IS 7
Step-by-step explanation:
CAUSE UR MOM IS A TRASHIE i'm sorry i meant YO MAMA
Final answer:
Kate can make 4 small flags from 2/3 yards of fabric since each flag requires 1/6 yards of fabric.
Explanation:
Kate has 2/3 yards of fabric and each small flag requires 1/6 yards of fabric. To find out how many flags Kate can make, you divide the total amount of fabric by the amount needed for one flag:
2/3 yards \/ 1/6 yards = 4 flags.
Here's the step-by-step calculation:
First, recall that dividing by a fraction is the same as multiplying by its reciprocal. In this case, the reciprocal of 1/6 is 6/1.
So, multiply 2/3 by the reciprocal of 1/6:
2/3 × 6/1 = 12/3 = 4.
Thus, Kate can make 4 small flags from the fabric she has.

Find the surface area of the regular hexagonal prism. Round your answer to the nearest hundredth.
Answer:
860.55 mm²
Step-by-step explanation:
The surface area of an hexagonal prism, also known as an octahedron, is given by the following formula (since we have the apothem):
S= 6*b*(a+h)
where b = is the side of the base, a is the apothem length, and h = the height
S = 6 * 8 * (4√3 + 11) = 48 * 17.92812 = 860.55 sq mm
Could have also have used another formula without the apothem:
S =3 * √3 * b² + 6 * b * h
S = 3 * √3 * 8² + 6 * 8 * 11 = 3√3 * 64 + 528 = 332.55 + 528 = 860.55 sq mm

Answer:
1.5 dollars/miles
Step-by-step explanation:
Given function [tex]y=3.75 + 1.5(x-1)[/tex] can be used to determine cost in dollars for a taxi ride of x miles.
Now we need to find about what is the rate of change of the cost in dollars with respect to the number of miles.
First we need to rewrite [tex]y=3.75 + 1.5(x-1)[/tex] in y=mx+b form
[tex]y=3.75 + 1.5(x-1)[/tex]
[tex]y=3.75 + 1.5x-1.5[/tex]
[tex]y=2.25 + 1.5x[/tex]
[tex]y=1.5x + 2.25[/tex]
comparing with y=mx+b, we get m=1.5
Hence rate of change of the cost in dollars with respect to the number of miles is 1.5.
