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:

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.

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.

Answer:

It is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.

Step-by-step explanation:

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.

Answer:

-12

Step-by-step explanation:

× x 2 = 2x

2x/3= -8x3/2

x = -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

Answer:

Step-by-step explanation:

divide both sides by 2

(x+1)(2)/2=9/2

simplify

x+1=9/2

subtract 1 from both sides

x+1-1=9/2-1

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.

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 )

The equation representing the situation is c = 3.5b

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.

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

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.
