Answer:
The hose is ~70.71 ft long.
Step-by-step explanation:
We need to use Pythagorean theorem to figure this out. ( A^2 + B^2 = C^2)
So we first need to square 50 two times, since that's the length and height of the garden. This equals 5000.
Then we just need to find the root of 5000! This rounds out to about 70.71 ft.
Hope I could help! :)
The length of the hose which is stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft
What is the diagonal of the square?The diagonal of the square is the distance from opposite vertices of it. There are two diagonals in a square which are equal in measure.
To find the diagonal of the square, the following formula is used.
d=a√2
Here, (a) is the length of the side of the square.
The side of a square garden is 50 ft long. One hose is stretch from one corner of the garden to another corner across the diagonal of it. Thus, the length of the diagonal is,
d=a√2
d=(50)√2
d=70.72 ft
Thus, the length of the hose which is stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft

Combing like terms you have 0.25k - k = -0.75k
and 1.5 - 3.5 = -2.0
The answer would be -0.75k - 2.0
0.25k + 1.5 - k - 3.5
You must combine like terms. Like terms are the numbers with the same variable (letter) attached (in this case the numbers with the letter k are like terms)
(0.25k + (-k) )+ 1.5 - 3.5 <<<Remember that a variable with no number in front of it still has and invisible 1
(0.25k + (-1k) ) + 1.5 - 3.5
-0.75k + 1.5 - 3.5
Numbers without any variable are also like terms
-0.75k + 1.5 - 3.5
-0.75k -2

Solve x2 + 1/2x +1/16=4/9
Answer:
x = 0.417 or x = -0.917
Step-by-step explanation:
We are given the following expression and we are to solve it for the variable x:
[tex] x ^2 + \frac { 1 } { 2 } x + \frac { 1 } { 1 6 } = \frac { 4 } { 9 } [/tex]
We will find the least common multiple of 2. 6 and 9:
[tex]x^2 \times 144 +\frac{1}{2}x \times 144 +\frac{1}{16} \times 144 = \frac{4}{9} \times 144[/tex]
Simplifying it to get:
[tex]144x^2+72x+9=64[/tex]
[tex]144x^2+72x+9-64=0[/tex]
[tex]144x^2+72x-55=0[/tex]
Using the quadratic formula to solve for x:

what is
3*2 [ -2 3 0
-4 2 6
6 -5 6 ]
this is a matrix question.
Answer:
B
Step-by-step explanation:
Given
[tex]\left[\begin{array}{ccc}-2&3&0\\-4&2&6\\6&-5&6\end{array}\right][/tex]
The product of 3x2 will be six.. We have a scalar which has to be multiplied by the matrix. The method of multiplying a scalar with a matrix is to multiply each element of the matrix by the scalar.
After multiplication the matrix will be:
[tex]\left[\begin{array}{ccc}-12&18&0\\-24&12&36\\36&-30&36\end{array}\right][/tex]
So, B is the correct answer..
To solve this question, you need to perform a scalar multiplication of the matrix by 3*2. Scalar multiplication involves multiplying every element of the matrix by the scalar value.
First, let's find the scalar value:
3 * 2 = 6
Now, let's multiply every element in the matrix by the scalar value 6:
Original matrix:
[ -2, 3, 0 ]
[ -4, 2, 6 ]
[ 6, -5, 6 ]
After scalar multiplication by 6:
[ -2*6, 3*6, 0*6 ]
[ -4*6, 2*6, 6*6 ]
[ 6*6, -5*6, 6*6 ]
Performing the multiplication for each element gives us:
[ -12, 18, 0 ]
[ -24, 12, 36 ]
[ 36, -30, 36 ]
The resulting matrix after multiplying by the scalar value of 6 is:
[ -12, 18, 0 ]
[ -24, 12, 36 ]
[ 36, -30, 36 ]
So the correct answer to the given matrix question is the matrix displayed above.

(x + k) is a factor of f(x)
If (x+k) is a factor of f(x), then f(-k) = 0. This is known as the factor theorem.
It states that if a polynomial f(x) has a factor of (x-a), then f(a) = 0.
In this case, since (x+k) is a factor of f(x), we can substitute -k for x in the factor theorem to get f(-k) = 0.

If it takes Bianca 30 minutes to bake 2 pans of brownies, how many pans of brownies can she bake in 7 hours?
Answer:
Bianca can make 28 pans of brownies in 7 hours
Step-by-step explanation:
As we know, 1 hour = 60 minutes
so, 1/2 hour = 30 minutes
Bianca takes 1/2 hour to make pans of brownies = 2 pans
Bianca takes 1 hour to make pans of brownies = 2 / (1/2) pans
Bianca takes 7 hour to make pans of brownies = 4 * 7 pans
= 28 pans
So, Bianca can make 28 pans of brownies in 7 hours.
An airplane can travel 325 mph in still air. If it travels 1360 miles with the wind in the same length of time it travels 1240 miles against the wind, what is the speed of the wind? Set up an equation and solve it.
The answer is:
The speed of the wind is 150mph.
Why?To calculate the speed of the wind, we need to write two equations using the given information about the speed when the airplane was traveling with the wind and against the wind, considering that it travel the same length of time.
So, writing the equations, we have:
Traveling with the wind:
We know that the speed of the airplane is 325 mph and it travels 1360 miles with the wind, so, for the equation, we have:
[tex]distance=(AirplaneSpeed+WindSpeed)*t[/tex]
[tex]1360miles=(325mph+WindSpeed)*t[/tex]
[tex]t=\frac{1360miles}{325mph+WindSpeed}[/tex]
Traveling against the wind:
We know that the speed of the airplane is 325 mph and it travels 1240 miles with the wind, so, for the equation, we have:
[tex]distance=(AirplaneSpeed-WindSpeed)*t[/tex]
[tex]1240miles=(325mph-WindSpeed)*t[/tex]
[tex]t=\frac{1240miles}{325mph-WindSpeed}[/tex]
Then, making making equal the time, we have:
[tex]\frac{1360miles}{325mph+WindSpeed}=\frac{1240miles}{325mph-WindSpeed}[/tex]
[tex]\frac{1360miles}{325mph+WindSpeed}=\frac{1240miles}{325mph-WindSpeed}\\\\(1360miles)*(325mph-WindSpeed)=(1240miles)*(325mph+WindSpeed)\\\\442000miles.mph-1360miles*WindSpeed=403000miles.mph+1240miles*WindSpeed\\\\442000miles.mph-403000miles.mph=1240miles*WindSpeed+1360miles*WindSpeed\\\\39000miles.mph=2600miles*Windspeed\\\\WindSpeed=\frac{39000miles.mph}{2600miles}=150mph[/tex]
Hence, we have that the speed of the wind is 150mph.

If f(x) = –2x+8 and g(x) = Square root of X+7,
what is (fºg)(2)
Answer:
(fog)(2)=2
Step-by-step explanation:
Given
f(x)= -2x+8
and
g(x)= √(x+7)
For finding (fog)(2), we have to find (fog)(x) first
In order to find (fog)(x) we will put the value of g(x) in f(x) in place of x.
(fog)(x)= -2g(x)+8
Putting the value of g(x)
(fog)(x)= -2√(x+7)+8
We have to find (fog)(2), so we have to put at the place of x in the composition
(fog)(x)= -2√(2+7)+8
(fog)(x)= -2√9+8
= -2(3)+8
= -6+8
=2
So,
(fog)(2)=2 ..

We multiply by the reciprocal of the second fraction:
[tex]- \frac{10}{19} \times ( - \frac{7}{5} )[/tex]
We cancel out the common factors to obtain:
[tex]- \frac{2}{19} \times ( - \frac{7}{1} )[/tex]
We multiply to get
[tex]\frac{ - 2 \times - 7}{19 \times 1} [/tex]
This simplifies to :
[tex] \frac{14}{19} [/tex]
The correct answer is C
The answer is:
Option C.
[tex]\frac{14}{19}[/tex]
Why?To perform fraction division, we need to follow the convert the expression and multiply the first fraction (numerator) by the inverse of the second fraction (denominator).
For example:
[tex]\frac{\frac{a}{b} }{\frac{c}{d} }=\frac{a}{b}*\frac{d}{c}[/tex]
So, we are given the following expression:
[tex]-\frac{10}{19}\div (-\frac{5}{7})[/tex]
Which is equal to:
[tex]\frac{-10}{19}\div (\frac{-5}{7})[/tex]
Then, calculating we have:
[tex]\frac{-10}{19}\div (\frac{-5}{7})=\frac{10}{19}*\frac{7}{5}\\\\\frac{10}{19}*\frac{7}{5}=\frac{10*7}{19*5}=\frac{70}{95}\\\\\frac{70}{95}=\frac{5*14}{5*19}=\frac{14}{19}[/tex]

A car travels at 40 miles per hour. Deb wrote the equation ys 40x, Deb then graphed the
equation and noticed that the point (3,120) was on the line, What does this point represent?
A.The car traveled 43 miles
B.120 hours,
C.The car traveled 120 miles In 3 hours,
D. The car traveled 3 miles In 120 hours,
E. The car traveled 120 miles In 40 hours,
Answer:
C
Step-by-step explanation:
The equation represents speed as a function of time. The point (3,120) implies that the car with a speed of 40 miles per hour, travelled a total of 120 miles in a time span of 3 hours.
Explanation:In this scenario, the equation ys = 40x relates the speed of the car (40 miles per hour) to the time travelled (x in hours). The 'y' in the equation represents the distance travelled by the car. So, when interpreting the point (3,120) on the graph for this equation, '3' refers to time (hours) and '120' refers to distance travelled (miles).
Thus, the point (3,120) on the graph signifies that the car travelled 120 miles in 3 hours, so the correct answer is C. The car traveled 120 miles In 3 hours.

Which pairs of angles in the figure below are vertical angles?
Check all that apply.
ANSWER
A. <AKC and <TKI
D. <IKR and <AKP
EXPLANATION
Vertical angles are also called X-angles.
They are angles in the opposite corners of a figure that looks like X.
From the diagram, the options that are vertical angles are:
A. <AKC and <TKI
D. <IKR and <AKP
The correct answers are A and D.
Answer:
A and D.
Step-by-step explanation:
A pair of angles are vertical if both measure the same and both are opposite by a vertex. Then, in the figure we have that
∠AKC and ∠TKI are vertical angles
∠AKP and ∠PKI are not vertical angles (∠PKI measures more than ∠AKP and these angles are not opposite by a vertex).
∠AKT and ∠PKC are not vertical angles (same reason as the second option).
∠IKR and ∠AKP are vertical angles.

What is the vertex of f(x) = | 8x + 8| - 3?
Answer:
(-1, -3)Step-by-step explanation:
Vertex of y = |x| have the coordinates (0, 0).
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units to the left
f(x - n) - shift the graph n units to the right
nf(x) - stretches/shrinks vertically
f(nx) - stretches/shrinks horizontally
We have
f(x) = |8x + 8| - 3 = |8(x + 1)| - 3 = |8| · |x+1| - 3 = 8|x + 1| - 3
g(x) = |x| → f(x) = 8g(x + 1) - 3
vertically streched by 8 (0, 8 · 0) → (0, 0)
shifted 1 unit to the left (0 - 1, 0) → (-1, 0)
shifted 3 units down (-1, 0 - 3) → (-1, -3)

what is the general form of the equation of the given circle with center A ?
Answer:
the equation of circle is x² + y² + 6x - 24y + 128 = 0
Step-by-step explanation:
To find the general form of the equation of the circle with center A (-3, 12) and radius r=5, we simply use this formula;
General Equation of a circle is (x - a)² + (y-b)² = r²
(a,b) are the two point at the center of the circle which are (-3, 12)
which implies a = -3 and b = 12
r is the radius of the circle which is given as 5 from the above diagram
to get r², we simply square 5 and so r² = 25
We can now plug in the values of our variables into the equation
(x - a)² + (y-b)² = r²
(x - [-3])² + ( y - 12)² = 5²
(x +3)² + ( y - 12)² = 5²
we will expand all the brackets
x² + 6x + 9 + y² -24y + 144 = 25
x² +6x + y² -24y + 153 = 25
Take 25 to the left hand side of the equation
x² +6x + y² -24y + 153 - 25 = 0
x² +6x + y² -24y + 128 = 0
Rearranging the equation to give us a standard form of the equation of the circle, we have;
x² + y² + 6x - 24y + 128 =0
{Note: (x + 3)² = (x+3)(x+3) = x² + 6x + 9 and
(y - 12)² = (y -12)(y-12) = y² - 24y + 144}
Therefore the general form of the equation of a circle with center(-3, 12) and radius 5 is x² + y² + 6x - 24y + 128 =0

If m < 0, then the function is decreasing
==================================================
Q1.y = -2x - 1 → m = -2 < 0 and b = -1

In the table illustrating the impacts resulting from human activities, the most fitting combination is the one stating that clearing forest areas to construct an airport leads to an increase in pollution, while the vegetation cleared for a power plant results in the contamination of water.
This pairing accurately reflects the environmental consequences associated with these specific human actions. When forests are cleared for airport construction, it often involves disrupting ecosystems, releasing pollutants, and contributing to air pollution.
On the other hand, clearing vegetation for a power plant can lead to water contamination, potentially through the release of pollutants into nearby water sources. This representation effectively highlights the diverse environmental impacts of human activities on both air and water quality, emphasizing the importance of responsible practices to mitigate these detrimental effects. Hence the correct option is 2.
Option 2 is correct. It directly links human activities to negative environmental consequences like sound pollution from airport construction and water contamination from power plant development.
Forest area cleared to construct an airport leading to an increase in sound pollution: This illustrates a direct impact of human activity on the environment. Clearing forests for infrastructure development like airports often leads to increased noise pollution due to aircraft operations and associated activities.
Vegetation cleared to construct a power plant leading to contamination of water: Again, this demonstrates a direct consequence of human activity. The clearance of vegetation for industrial purposes such as power plants can result in soil erosion and runoff, which may contaminate nearby water sources with sediments, chemicals, or pollutants.
Both of these impacts highlight tangible and negative consequences of human activities on the environment, emphasizing the importance of considering the environmental impacts of development and infrastructure projects. Therefore, option 2 effectively portrays the impacts resulting from human activities.

Answer: 140 degree
Step-by-step explanation: The line LMU is basically 180, so what you'll do is 90 degree KLM plus 50 degree LMK which will give you 140 degree. A whole triangle is a supplementary angle so it's 180 degree. To find KMU, you do (180 - 140) - (180 - 40) = 140. So the answer for angle KMU is 140.
