Is it possible to construct a quadrilateral from any 4 given measurements of its sides? State a reason for your answer.
Answer:
It is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.
Step-by-step explanation:
We know that the Quadrilateral is a 2D closed figure with four sides.The Quadrilateral has four vertices or corners.We are asked to tell whether it is possible to construct a quadrilateral from any 4 given measurements of its sides.
Well, in order to construct a quadrilateral from any 4 given measurements of its sides, we need at least five dimensions.
With only 4 given measurements of its sides, we won't know any of its angles.
Thus, it is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.
A bouncing ball reaches a height of 27 feet at its first peak 18 feet at its second peak and 12 feet at its third peak Describe how a sequence can be used to determine the height of the ball when it reaches its fourth peak
Answer: 8
Step-by-step explanation:
A Geometric sequence can be used:
To Model this sequence you need to use this formula
A (subscript n) = Ar(n-1)
a = value of the first term
n = the # of the term you want to find (For example, if you want to find the term number 3, it is 12)
r = the common ratio, this is obtained by dividing the second term in the sequence by the first.
So the value of r is = 2/3 because 27 times 2/3 = 18 which is the second term
n = 4 since you want to find the 4th term in the sequence
Plug it in and results are
4th term = 27(2/3)^(4-1) = 8
Sample Response:
There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.

Because of road construction in one city, commuters were advised to plan that their Monday morning commute would take 150% of their usual commuting time. Explain what this means.
Answer:
Kindly check explanation
Step-by-step explanation:
Let :
Original commute time = x
Commute time due to road construction = 150% of original commute time
Hence, commute time due to road construction :
(150 / 100) * x
0.15x
Hence, the implication of the road construction in progress means that it will now take additional half of the usual time it takes them on a Monday morning.
For instance, an individual whose usu commute time is 10 minutes in the morning will now take :
1.5x = 1.5(10) = 15 minutes commute time on a Monday morning.

Answer:
(3, 1 )
Step-by-step explanation:
The centre of the circle is at the midpoint of the diameter.
Given endpoint (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (9, 7) and (x₂, y₂ ) = (- 3, - 5 ) , then
midpoint = ( [tex]\frac{9-3}{2}[/tex], [tex]\frac{7-5}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex], [tex]\frac{2}{2}[/tex] ) = (3, 1 )

what’s the answer to
2(s-10)=12
Answer: s = 16
2(s - 10) = 12
distribute the 2
2s - 20 = 12
add 20 to both sides
2s = 32
divide both sides by 2
s = 16
you can then check your work by putting in the 16
2 (16-10) = 12
2 (6) = 12
12 = 12

Over which interval was the average rate of change per hour the greatest?
Answer:
its b
Step-by-step explanation:
Time interval 6:53 a.m to 8:53 a.m, the average rate of change per hour the greatest.
Given,
Time Temperature (°F)
5:53 a.m. 60.1
6:53 a.m. 60.1
8:53 a.m. 66.9
11:53 a.m 75.2
3:53 p.m. 78.1
From 5:53 a.m. to 6:53 a.m. the temperature is constant. So average rate of change per hour is 0.
From 6:53 a.m to 8:53 a.m. the temperature is increasing from 60.1 to 66.9 or 6.8 in 2 hours . So average rate of change per hour is [tex]\frac{6.8}{2} =3.4[/tex].
From 8:53 a.m. to 11:53 a.m the temperature is again increasing from 66.9 to 75.2 or 8.3 in 3 hours. So average rate of change per hour is [tex]\frac{8.3}{3} =2.76[/tex].
From 11:53 a.m to 3:53 p.m. the temperature is again increasing from 75.2 to 78.1 or 2.9 in 4 hours. So average rate of change per hour is [tex]\frac{2.9}{4}=0.725[/tex].
Now clearly from the above points time interval 6:53 a.m to 8:53 a.m, the average rate of change per hour the greatest.

Harold can buy 2 pounds of bananas for $7. Write an equation to represent the cost, c , for b bananas.
The equation representing the situation is c = 3.5b
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Harold can buy 2 pounds of bananas for $7.
Since, he can buy 2 pounds in $7 so, 1 pound in = 7/2 = $3.5
So, when he will buy b pounds of bananas he will spend = $3.5b
So, if c is the total cost for b pounds of bananas, then the equation representing the total cost for b pounds of bananas will be,
c = 3.5b
Hence, c = 3.5b is the equation that represent the cost, c, for b bananas.

Step-by-step explanation:
Ziad tells his son Marc: " This year my age is triple yours, but in 10 years, it will be the double". Find their ages.
Answer:
Ziad is 30 years old.
Marc is 10 years old.
Step-by-step explanation:
We will use m to represent Marc's age this year, and z to represent Ziad's age this year.
This year:
z = 3m
To show their relative ages in ten years time:
z + 10 = 2(m+10)
We can rearrange this to make m the subject.
z + 10 = 2m + 20
z = 2m + 10
We also know that m = 3z. We can substitute this value into our equation.
3m = 2m + 10
m = 10
Use z = 3m to find that z = 30.

Answer:
the turning point is (-2,-1)
i dont know the turning point but i hope this helps
Step-by-step explanation:
Answer:
a) (-2 , -1)
b) (-1 , 0) and (-3 , 0)
Step-by-step explanation:
For part a)
We can find the coordinates of the turning point by seeing at the graph where it turns the other way or in simpler words the axis of symmetry so if see the graph the axis of symmetry is the line x = -2 so that means the turning point is (-2 , -1).
For finding the turning point mathematically we compare the equation to its standard form which is:
[tex]x^2+4x+3=a(x-h)^2+k[/tex]
where h is the x coordinate and k is the y coordinate of the turning point of the equation (h , k) = (x , y).
so just solve the left side,
[tex]a(x-h)^2+k\\a((x)^2-2(x)(h)+(h)^2)+k\\a(x^2-2xh+h^2)+k\\\\ax^2-2ahx+ah^2+k=x^2+4x+3\\[/tex]
and so we compare the coefficients of x^2 on the right and left side we get
[tex]a=1[/tex]
if we compare the coefficients of x on the right and left side we get
[tex]-2ah=4\\-2(1)h=4\\-2h=4\\h=\frac{4}{-2}\\\\h=-2[/tex]
now we compare the constants on the right and left side we get
[tex]ah^2+k=3\\(1)(-2)^2+k=3\\(1)(4)+k=3\\4+k=3\\k=3-4\\k=-1[/tex]
so the turning point is (-2 , -1) proven mathematically and graphically as well
For part b)
Roots of the equation are also called as x-intercepts which means where the graph intersects/cuts the x-axis so if see the graph it cuts the x-axis at 2 points firstly at -3 and then at -1 so the roots of the equation would be (-1 , 0) and
(-3 , 0) the y coordinate is zero when the points lies on the x-axis.
for mathematically solving the equation we would equate the equation to zero
[tex]y=x^2+4x+3\\x^2+4x+3=0[/tex]
Now solve it by either factorizing or by using the quadratic formula we would get two values for x those are the roots of the equation
we solve it by factoring
[tex]x^2+4x+3=0\\x^2+3x+x+3=0\\x(x+3)+1(x+3)=0\\(x+3)(x+1)=0\\x=-3\ ,\ x=-1\\[/tex]
proven mathematically as well as graphically.
Prove that (Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A
Answer:
The answer is below
Step-by-step explanation:
We need to prove that:
(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.
Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.
Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A
[tex]\frac{\sqrt{secA-1} }{\sqrt{secA+1} } +\frac{\sqrt{secA+1} }{\sqrt{secA-1} } =\frac{(\sqrt{secA-1)}(\sqrt{secA-1})+(\sqrt{secA+1)}(\sqrt{secA+1}) }{(\sqrt{secA+1})(\sqrt{secA-1}) } \\\\=\frac{secA-1+(secA+1)}{\sqrt{sec^2A-secA+secA-1} } \\\\=\frac{2secA}{\sqrt{sec^2A-1} } \\\\=\frac{2secA}{\sqrt{tan^2A} } \\\\=\frac{2secA}{tanA} \\\\=\frac{2*\frac{1}{cosA} }{\frac{sinA}{cosA} }\\\\= 2*\frac{1}{cosA}*\frac{cosA}{sinA}\\\\=2*\frac{1}{sinAA}\\\\=2cosecA[/tex]
