Hi!
The vertex is the highest or lowest point on a graph, also known as the maximum/minimum. It is the turning point for the parabola.
In this case, it has a maximum, because the parabola points downward.
Using the graph, we can see the vertex is at point
(3, 4)
Answer:
(3,4)
Step-by-step explanation:
The vertex is a point that is the maximum or minimum of the parabola. (3,4) is the highest point on that parabola so it's a vertex

Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second. Use D for depth (in kilometers) and S for the speed of sound (in meters per second), and find a linear formula for S as a function of D.
Answers
Answer:
A linear formula for S as a function of D is S=17D+1534
Step-by-step explanation:
We are supposed to find a linear formula for S as a function of D.
Equation of line : y = mx+c
We are given that At the surface, the speed of sound is 1534 meters per second.
c = 1534
We are given that for each increase in depth by 1 km, the speed increases by 17 m/s
So, Slope = m = 17
Substitute the values in equation
y=17x+1534
x denotes depth
y denotes speed
We are given that Use D for depth and S for the speed of sound
So, S=17D+1534
Hence a linear formula for S as a function of D is S=17D+1534

C. 0.008
D. 0.6
Answers
Step-by-step explanation:
The exponent of a number describes how many times to multiply the number by itself.
[tex](0.2)^3=0.2 \times 0.2\times 0.2[/tex]
Multiply;
[tex]0.2 \times 0.2 \times 0.2[/tex]
[tex]0.04 \times 0.2[/tex]
[tex]0.008[/tex]
[tex]\boxed{C. \: 0.008 \: is \: the \: correct \: option.}[/tex]
1. Change 0.2 into fraction form.
[tex]0.2 = \frac{2}{10}[/tex]
2. Simplify (2/10)³.
[tex](\frac{2}{10})^{3}[/tex]
⇒ [tex](\frac{2}{10})(\frac{2}{10})(\frac{2}{10})[/tex]
⇒ [tex]\frac{8}{1000}[/tex]
3. Change 8/1000 into decimal form.
[tex]\frac{8}{1000} = \frac{0.8}{100} = \frac{0.08}{10} = \frac{0.008}{1} = 0.008[/tex]
Thus, Option C is correct.

Answers
Answer:
€107.69
Step-by-step explanation:
If $2=€1.78 then $1= €0.89
0.89*121= €107.69
The 107.69 Euros will Roscoe have for trip to Germany.
It is required to find how many Euros will Roscoe have for trip to Germany.
What is arithmetic?The arithmetic refers to working with numbers by doing addition, subtraction, multiplication, and division. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.
Given:
Roscoe is exchanging $ 121 for Euros.
If $2 can be exchanged for 1.78 Euros.
$2=€1.78
then $1= €0.89

A statistician at a metal manufacturing plant is sampling the thickness of metal plates. If an outlier occurs within a particular sample, the statistician must check the configuration of the machine. The distribution of metal thickness has mean 23.5 millimeters (mm) and standard deviation 1.4 mm. Based on the two-standard deviations rule for outliers, which is the greatest thickness that would require the statistician to check the configuration of the machine?
Answers
Answer: 26.3 mm
Step-by-step explanation:
According to the two-standard deviations rule for outliers, the values that does not lie within 2 standard deviations from mean are outliers.
If Mean = 23.5 millimeters (mm) and standard deviation = 1.4 mm
Then, greatest thickness need to check = mean + 2 (standard deviation)
= 23.5 + 2(1.4)
= 23.5 + 2.8
= 26.3 mm
hence, the greatest thickness that would require the statistician to check the configuration of the machine = 26.3 mm.

3. Consider the line
2x + 5y = -10. What is the
slope of the line parallel to this line?
Answers
Answer:
The slope of the parallel line to the line 2x + 5y = -10 is [tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
Parallel lines have equal slopes and different y-intercepts
To find the slope of the line from the equation of the line, then put the equation in the form y = m x + b, where
m is the slopeb is the y-interceptLet us solve the question
∵ The equation of a line is 2x + 5y = -10
→ Put the equation in the form above
→ Subtract x from both sides to move 2x from the left side to the
right side
∴ 2x - 2x + 5y = -10 - 2x
∴ 5y = -10x - 2x
→ Make the coefficient of y equal 1 by dividing all terms by 5
∵ [tex]\frac{5y}{5}=-\frac{10}{5}-\frac{2x}{5}[/tex]
∴ y = -2 - [tex]\frac{2}{5}x[/tex]
→ Compare it by the form of the equation above
∴ m = [tex]-\frac{2}{5}[/tex]
∴ The slope of the given line is [tex]-\frac{2}{5}[/tex]
→ We need the slope of the line which is parallel to the given line
∵ Parallel lines have the same slopes
∴ The slope of the parallel line to the line 2x + 5y = -10 is [tex]-\frac{2}{5}[/tex]

the area of rectangular garden is 27000m2.if the ratio of length and beradth is 10:3 findits perimeter
Answers
Given :
The area of rectangular garden is 27000m² .The ratio of length and breadth is 10 : 3 .⠀
To Find :
The perimeter of the rectangular garden.⠀
Solution :
Let us assume the length as 10x m and breadth as 3x m .
⠀
We know that,
[tex]{ \longrightarrow{\quad \sf \pmb{ Length \times Breadth = Area_{(rectangle)}}} }[/tex]
⠀
Now, substituting the values in the formula :
[tex]{ \longrightarrow{\quad \sf{ 10x \times 3x = 27000 }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ 30 {x}^{2} = 27000 }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ {x}^{2} = \dfrac{27000}{30} }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ {x}^{2} = 900 }}} [/tex]
[tex]{ \longrightarrow{\quad \sf{ {x}= \sqrt{900} }}} [/tex]
[tex]{ \longrightarrow{\quad \bf{ {x}= 30 }}} [/tex]
⠀
Therefore,
Length = 10x m = 10(30) m = 300 mBreadth = 3x m = 3(30) m = 90 m⠀
Now,
We know that,
[tex]{ \longrightarrow{\quad \sf \pmb{Perimeter_{(rectangle)}=2(Length + Breadth) }} }[/tex]
⠀
Substituting the values in the formula :
[tex]{ \longrightarrow{\quad \sf {Perimeter_{(rectangle)}=2(300 + 90) }} }[/tex]
[tex]{ \longrightarrow{\quad \sf {Perimeter_{(rectangle)}=2(390) }} }[/tex]
[tex]{ \longrightarrow{\quad \bf \pmb {Perimeter_{(rectangle)}=780 }} }[/tex]
⠀
Therefore,
The perimeter of the rectangular garden is 780 m .The perimeter of the rectangle whose area is 27000 m² is 780 m.
What is the perimeter of a rectangle?The perimeter of a rectangle is the determinating of all the sides of the rectangle. In the given question, we have the following parameters:
Given that:
The area of the rectangle = 27000 m²The ratio of the length and the breadth is 10: 3It implies that, if the length is 10x, the breadth is 3x
The area of a rectangle = length × breath
27000 m² = (10x) × (3x)
27000 m² = 30x²
x² = 27000/30
x² = 900
x = √900
x = 30
Now, we can say that:
The length = 10(30) = 300The breath = 3(30) = 90The perimeter of the rectangle = 2(length + breadth)
The perimeter of the rectangle = 2(300 + 90)
The perimeter of the rectangle = 780 m
