Answer:

The x-intercept of the function is 4 which represents the total time of the trip, in hours.

Step-by-step explanation:

Since Skylar was a distance of 0 miles from City A after 4 hours, the x-intercept of 4 represents how many hours it took Skylar to drive from her house to City A.

Have a good day :)

The x- intercept is 4 hours.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δxwhere,m is the slope

Given:

D=120-30t.

According to slope - intercept form

y= mx+ b

where m is the slope and b is the y intercept.

So,  the x-intercept

0= 120- 30t

t= -120/ (-30)

t= 4

Hence, the x- intercept is 4 hours.

The area of a shape is the amount of space it can occupy.

The value of r is 13

From the question (see attachment), we have:

[tex]\mathbf{A =176}[/tex] --- area of the shaded region

[tex]\mathbf{w = 2}[/tex] --- the width of the shaded region

The area of the complete circle would be:

[tex]\mathbf{A_1 =\pi (r + w)^2}[/tex]

The area of the small circle is:

[tex]\mathbf{A_2 =\pi r^2}[/tex]

So, the area of the shaded region is:

[tex]\mathbf{A = A_1 - A_2}[/tex]

Substitute known values

[tex]\mathbf{176 =\pi (r + w)^2 - \pi r^2 }[/tex]

Substitute 2 for w

[tex]\mathbf{176 =\pi (r + 2)^2 - \pi r^2 }[/tex]

Expand

[tex]\mathbf{176 =\pi (r^2 + 4r + 4) - \pi r^2 }[/tex]

Open brackets

[tex]\mathbf{176 =\pi r^2 + 4\pi r + 4\pi - \pi r^2 }[/tex]

Cancel out line terms

[tex]\mathbf{176 =4\pi r + 4\pi }[/tex]

Divide through by 4

[tex]\mathbf{44 =\pi r + \pi }[/tex]

Factor out pi

[tex]\mathbf{44 =\pi(r+ 1) }[/tex]

Divide through by pi

[tex]\mathbf{r + 1= \frac{44}{ \pi} }[/tex]

Substitute 22/7 for pi

[tex]\mathbf{r + 1= \frac{44}{ 22/7} }[/tex]

Using a calculator, we have

[tex]\mathbf{r + 1= 14}[/tex]

Solve for r

[tex]\mathbf{r= 14 -1}[/tex]

[tex]\mathbf{r= 13}[/tex]

Hence, the value of r is 13

Answer:Nope

Step-by-step explanation:

The equation, b(t) = - 5t ^ 2 + 10t + 6, is a parabola with a vertex.  We must find whether that vertex is equal to or exceeds 12m.  One can graph the equation and find that the vertex is at (1,11), below the 12.  It cannot reach 12 meters.

[One may also differentiate the equation and set it equal to zero (the point at which the slope of the parabola is zero, which will be at the vertex as it begins downward)].

Answer:

  8. GH = 49; HJ = 35; JG = 35

  9. KL = 26, LM = 26, MK = 20

Step-by-step explanation:

8. The sides opposite the marked angles are congruent.

  JG = JH

  3x +8 = 35

  3x = 27 . . . . . . . subtract 8

  x = 9 . . . . . . . divide by 3

We already know JG and JH, so we only need to find GH:

  GH = 6x -5 = 6(9) -5 = 54 -5 = 49

Then the side lengths are ...

  GH = 49, HJ = 35, JG = 35

__

9. This, too, is an isosceles triangle.

  LK = LM

  26 = 2y+8

  18 = 2y . . . . . . . subtract 8

  y = 9 . . . . . . . divide by 2

  KM = 3(9) -7 = 27 -7 = 20

Then the side lengths are ...

  KL = 26, LM = 26, MK = 20

Answer: y=4x-5

Step-by-step explanation:

The slope of y=4x+23 is:4 m=4  

The parallel line needs to have the same slope of 4

Solve it using the "point-slope" equation of a line:   y− y1 = 2(x − x1)

substitute or put in the point (2,3):

y − (3) = 4(x − 2)

y - 3 = 4x - 8      

 put it in slope intercept form y = mx + b  

y  = 4x − 5

Step-by-step explanation:

Answer:

1225.50

Step-by-step explanation:

14% of 1075 =0.14 x 1075=150.5

1075 +150.5 = 1225.5

The 14% of $1075 is $150.5 thus the total cost for the hotel room overall 5 nights including tax will be $1225.50.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

The total cost before tax was $1,075.

The tax rate is 14%

14% of $1075 will be,

(14/100)1075 = $150.5

Total cost includes tax = $1075 + $150.5 = $1225.50

Hence "The 14% of $1075 is $150.5 thus the total cost for the hotel room overall 5 nights including tax will be $1225.50".
