Answer:
The Pool should be 10 feet wider
Step-by-step explanation:
The rectangngle shaped pool will have 4 sides...
If the Pool is 60 feet long then 120 feet should be covered by Tiles.
so only Tiles of 20 feet are left...
Hence the border will be 10 on one side and 10 on the other side
The Pool should be 10 feet wider
The calculation is as follows:
The rectangle-shaped pool will have 4 sides
In the case when the Pool is 60 feet long then 120 feet should be covered by Tiles.
Thus, only Tiles of 20 feet are left...
Therefore,
Hence the border will be 10 on one side and 10 on the other side

Which graph represents the inequality:

I believe the answer is A
Select the appropriate response.
An isosceles triangle has vertices at (1,1) and (3, 3). Which of the following could be
the coordinates of the third vertex?
A. (2.1)
B. (3.2)
C. (4,1)
D. (5,1)
Choose
Answer:
D. (5,1)
Step-by-step explanation:
Because it is an isosceles triangle, the next point we choose must result in two sides with the same length. This means that either the two new sides are equal, or that one of the new sides is equal to the original side. If we wanted both of the new sides to be equal, they would have to be equal distance from the new point and one of the points of the original line. However, none of the options result in both new lines being the same length.
(2,1) would result in one new length being 1 unit long (2-1 x-coordinates) and the other being square root 5 (distance from point 2,1 to point 3,3 minus both coordinates and use Pythagoras). Points 3,2 and 4,1 yield the same result: Length 1=1 unit length 2=square root 5. Length 1 = 3 unit, length 2 = square root 5.
Therefore we are looking for a point which instead yields one length which is the same length as the original. The original length was 2^2 + 2^2 = c^2 = square root 8.
If we try the point 5,1 then we get two lengths of 4 and square root 8, it forms a isosceles triangle whose base line is parallel to the x-axis.
Sorry is my explanation was confusing, it's much easier to try and draw it on a grid and visualize it. Basically the overall idea is to test the side values you get by finding the distance between the points and going with the option which results in two sides with the same length.
Hope this helped!

Find all values of c such that f is continuous on (-[infinity], [infinity]). f(x) = { 3 - x^2 x less than or equal to c x, x > ca. c = -1 + squareroot 13/2, -1 - squareroot 13/2.b. c = 0. c. c = -1 = squareroot 13/2.d. c = 2.e. c = -1 + squareroot 13/2, 1 - squareroot 13/2.
Answer:
a) [tex]c=\frac{-1+\sqrt{13}}{2}[/tex] and [tex]c=\frac{-1-\sqrt{13}}{2}[/tex]
Step-by-step explanation:
The idea for the solution of this equation is to find the value of c where both parts of the piecewise-defined function are the same. So we need to take the parts of the function and set them equal to each other, so we get:
[tex]3-x^{2}=x[/tex]
and then solve for x. We move everything to one side of the equation so we get:
[tex]x^{2}+x-3=0[/tex]
and we use the quadratic formula:
[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
and we substitute:
[tex]x=\frac{-1\pm \sqrt{(1)^2-4(1)(-3)}}{2(1)}[/tex]
and solve
[tex]x=\frac{-1\pm \sqrt{1+12}}{2}[/tex]
[tex]x=\frac{-1\pm \sqrt{13}}{2}[/tex]
so our two answers are:
a) [tex]c=\frac{-1+\sqrt{13}}{2}[/tex] and [tex]c=\frac{-1-\sqrt{13}}{2}[/tex]
given g(x)=x^2 and h(x)= x-3 find (g ∘ h)(x)
Answer:
(g ∘ h)(x) = x² - 6x + 9Step-by-step explanation:
g(x) = x²
h(x) = x - 3
To find (g ∘ h)(x) substitute h(x) into g(x) that's for every x in g(x) replace it with h(x)
That's
(g ∘ h)(x) = ( x - 3)²
= x² - 3x - 3x + 9
We have the final answer as
(g ∘ h)(x) = x² - 6x + 9Hope this helps you
The supplement of an angle is 42 degrees less than 3 times the complement of the angle. What is the measure of the angle?
Answer: 24°
Step-by-step explanation:
Given the following :
supplement of an angle is 42 degrees less than 3 times the complement of the angle
Let the angle = θ
Supplement of angle = 180° - θ
Complement of angle = 90° - θ
Supplement of angle is also said to be:
(3 × complement) - 42° = 3(90° - θ) - 42°
= 270° - 3θ - 42° = 228° - 3θ
Hence,
180° - θ = 228° - 3θ
Solve for θ
-θ + 3θ = 228° - 180°
2θ = 48°
θ = 48°/2
θ = 24°

Answer:
x = 12
Step-by-step explanation:
Given that AB = 2, AD = x, BC = 2, CD = -16 + 2x, since A, B, C, D are said to be collinear, therefore:
AB + BC + CD = AD
2 + 2 + (-16 + 2x) = x
Use this equation to solve for x
2 + 2 - 16 + 2x = x
-12 + 2x = x
Subtract 2x from both sides
-12 + 2x - 2x = x - 2x
-12 = -x
Divide both sides by -1
[tex] \frac{-12}{-1} = \frac{-x}{-1} [/tex]
12 = x (negative cancels negative)
x = 12

- 34
Answer:
The number -34 belongs to:
✔️Integers and
✔️Rational numbers
Step-by-step explanation:
-34 is an integer because it can written without a fractional or decimal part.
Rational numbers are said to numbers that can actually be expressed as a fraction with integers. They have no fractional part.
For example, −34 is a rational number because it can be written as - 34/1.
-34 can be expressed as -34/17, given an integer.
-34 is NOT a whole number because whole numbers are positive numbers.
Which pair of points has a slope of 4? Question 4 options: (0, 4), (4, 0) (3, 0), (–1, –1) (1, 4), (–1, 4) (0, –3), (1, 1)
Answer:
(0,-3) and (1,1)
Step-by-step explanation:
In order to have a slope of 4, the y coordinates need to differ by 4, and the x coordinates by 1. This is because slope is equal to rise/run. Rise being difference in y value and run difference in x.
In this pair of coordinates, the y coordinates differ in +4 (-3 and 1) and the x coordinate differs by 1 (0 and 1).
Therefore this is the pair of points with a slope of 4.
Hope this helped!
The pair of points that has a slope of 4 is the coordinate points (0, –3), (1, 1)
The formula for calculating the slope of a line passing through two points is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We need to get which of the coordinates will result in a slope of 4.
Using the coordinate points (0, –3), (1, 1)
[tex]m=\frac{1-(-3)}{1-0}\\m=\frac{1+3}{1}\\m=\frac{4}{1}\\m=4[/tex]
Hence the pair of points that has a slope of 4 is the coordinate points (0, –3), (1, 1)

Find the distance from the point (0, 4, 3) to the plane 5x +1y +2z
Answer:
distance =
[tex] \sqrt{ \frac{10}{3} } [/tex]
Step-by-step explanation:
Without going through and deriving this (my blackboard doesn't have space and a textbook, teacher, or online tutorial is probably better for that), the equation for the distance from some point on the plane to some point in space is as follows:
[tex]distance = \frac{ax + by + cz - d }{ \sqrt{ {a}^{2} + {b}^{2} + {c}^{2} } } [/tex]
•Note that the d in the equation should actually be D but Brainly doesn't allow me to do uppercase letters on mobile it seems... Anyway, d in the equation represents the value which the equation of the plane is equal to. You only gave the plane equation so I assumed d=0 in my calculations.
•x, y, and z all come from the point which you want to find the distance to. So (x,y,z)=(0,4,3) here.
•a, b, and c all come from the components of the vector normal to the surface. For planes, it simply somes to be the coefficients in front of each part. So (a,b,c)=(5,1,2) here.
With that you just need to plug the information in and simplify for your answer. My work is in the attachment, comment with questions or if anything seems off.
Bill has a container that is shaped like a cube. He uses 125 cubes with a side length of 1 inch to fill the container completely. What is the edge length of the container? *****Hint: 1 inch cubes to fill a container is the volume of the cube Please answer quickly!!! Thank you.
Answer:
5 inches
Step-by-step explanation:
Given
Length of a cube = 1 inch
Required
Determine the edge length of the cube
If the container can take 125 cubes, then that's the volume
So:
[tex]Volume = 125in^3[/tex]
Volume of a cube is calculated as thus;
[tex]Volume = Length^3[/tex]
This gives;
[tex]Length^3 = 125[/tex]
Take cube root of both sides
[tex]Length = \sqrt[3]{125}[/tex]
[tex]Length = 5[/tex]
Hence, the length is 5 inches

The manager of a restaurant found that the cost to produce 200 cups of coffee is $65.00 , while the cost to produce 250 cups is $77.50 . Assume the relationship between the cost y to produce x cups of coffee is linear. a. Write a linear equation that expresses the cost, y, in terms of the number of cups of coffee, x. b. How many cups of coffee are produced if the cost of production is $135.00 ?
Answer:
a). y = 0.25x + 15
b). x = 480 cups
Step-by-step explanation:
(a). Let the equation of the linear function passing through a point (x', y') is,
y - y' = m(x - x')
'm' = slope of the line
b = y-intercept
Two points lying on the linear function will be (200, 65) and (250, 77.5).
Slope of the line 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{77.5-65}{250-200}[/tex]
= [tex]\frac{12.5}{50}[/tex]
= 0.25
Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,
y - 65 = 0.25(x - 200)
y - 65 = 0.25x - 50
y = 0.25x + 15
(b). For y = $135 we have to calculate the number of cups of coffee produced.
135 = 0.25x + 15
0.25x = 135 - 15
0.25x = 120
x = 480 cups
Therefore, 480 cups of coffee will be produced.

Find
(1) a + b,
(2) 2a + 3b,
(3) |a|, and |a − b|.
a = 5i + j, b = i − 2j
Answer:
Step-by-step explanation:
this problem is on vector
given the vectors
a = 5i + j, and
b = i − 2j
1. summation of vector a + b
[tex]= (5i+j)+(i-2j)\\\\=5i+j+i-2j\\\\[/tex]
collect like terms
[tex]=5i+i+j-2j\\\\=6i-j\\\\[/tex]
2. 2a + 3b
[tex]= 2(5i+j)+3(i-2j)\\\\=10i+2j+3i-6j\\\\[/tex]
collecting like terms we have
[tex]=10i+2j+3i-6j\\\\=10i+3i+2j-6j\\\\=13i-4j[/tex]
(3) |a|, and |a − b|.
|a|= |5i+j|
[tex]=\sqrt{5^2+1^2} \\\\=\sqrt{25+1} \\\\=\sqrt{26} \\\\= 5.1[/tex]
also,
[tex]|a - b|= |(5i+j) -(i-2j)| \\\\ a-b= 5i+j -i+2j \\\\ a-b=5i-i+j+2j \\\\a-b= 4i+3j\\\\[/tex]
[tex]|a -b|=\sqrt{4^2+3^2} \\\\|a -b|=\sqrt{16+9} \\\\|a -b|=\sqrt{25} \\\\|a -b|=25[/tex]
