Answer:

  see below

Step-by-step explanation:

Each point reflected in the x-axis will be as far below the axis as the original point is above the axis. The horizontal location of the point does not change; only the sign of the y-coefficient changes.

Answer:

The increment in the model is 106cm

Step-by-step explanation:

Given

[tex]Initial\ Height = 53cm[/tex]

[tex]Final\ Height = 159cm[/tex]

Required

Determine the increment

To do this, we simply subtract the initial height of the building from the final height

[tex]Increment = Final\ Height - Initial\ Height[/tex]

[tex]Increment = 159cm - 53cm[/tex]

[tex]Increment = 106cm[/tex]

Hence, the increment in the model is 106cm

Answer:5 percent

Answer:

The y-intercept is (0, 8)

The x-intercepts are (2, 0) and (4, 0)

The axis of symmetry is a vertical line at x = 3

The vertex is (3, -1)

The graph has a minimum value -1 at x = 3

The domain is {x: x ∈ R} ⇒ (-∞, ∞)

The range is {y: y ≥ -1} ⇒ [-1, ∞)

Step-by-step explanation:

By using the given figure

The figure represents a parabola (the graph of a quadratic function

∵ The parabola intersects the y-axis at point (0, 8)

∴ The y-intercept is (0, 8)

∵ The parabola intersects the x-axis at point (2, 0) and (4, 0)

∴ The x-intercepts are (2, 0) and (4, 0)

∵ The axis of symmetry of the parabola is a vertical line that passes

  through the vertex of it

∵ The x-coordinate of the vertex point is 3

∴ The axis of symmetry is a vertical line at x = 3

∵ The vertex of the parabola is the lowest point on the graph

∵ The lowest point is (3, -1)

∴ The vertex is (3, -1)

∵ The vertex point of the graph is the lowest

∴ The graph has a minimum value -1 at x = 3

∵ The domain is all values of x belong to the parabola

∵ x could be any real number

∴ The domain is {x: x ∈ R} ⇒ (-∞, ∞)

∵ The range is all the values of y from the lowest point

∵ The y-coordinate of the lowest point is -1

∴ The range is {y: y ≥ -1} ⇒ [-1, ∞)

Answer:

C. 60

Step-by-step explanation:

48+72=120

x=180-120

x=60

The value of x from the given diagram is 60 degrees

The sum of the interior angle of a triangle is 180 degrees. Since the two lines intersect parallel lines m and n, then;

Taking the sum of angle in the triangle;

m<3 + x + 72 = 180

48 + x + 72 = 180

120 + x = 180

x = 180 - 120

x = 60 degrees

Hence the value of x from the given diagram is 60 degrees

Answer:

[tex]\displaystyle\Huge \bf\red{\underline{\underline{ANSWER}}}

[/tex]

Let the speed of the train be x km/hr and the speed of the bus is y km/hr.

So according to question and using

[tex] \huge \boxed{\sf{Time = \frac{Distance}{speed}}}

[/tex]

Total distance =300 km

Mansi travels 60 km by train and 300−60=240 by bus in 4 minute,

[tex] \bf\frac{60}{x} + \frac{240}{y} = \red4

[/tex]

and 100 km by train, 300−100=200 by bus, and takes 10 minutes more,

[tex] \bf {\frac{100}{x} + \frac{200}{y} = 4 + \frac{1}{6} = \frac{24 + 1 }{6} = \purple{\frac{25}{6}}}

[/tex]

Now, let

[tex]\bf\color{blue}{\frac{1}{x} = a}[/tex]

and.

[tex] \bf \color{blue}{ \frac{1}{y} = b }[/tex]

[tex]\bfthen 60a+240b=4.............(1)[/tex]

[tex]\bf100a+200b=25/6----(2)[/tex]

multiply (1) by 5 and (2) by 6 we get

[tex]\bf300a+1200b=20..........(3)[/tex]

[tex]\bf600a+1200b=25...........(4)[/tex]

Subtracting (3) and (4) we get

[tex]\bf \green{−300a=−5}[/tex]

[tex]\bf{a = \frac{1}{60}}[/tex]

Putting the value of a in (1) we get

[tex]\bf{60 \times \frac{1}{60} + 240b = 4}[/tex]

[tex]

\bf240b = 3 \\ \\ \bf b = \frac{1}{80} [/tex]

Now ,

[tex] \bf\frac{1}{x} = a \\ \\ \bf \red{a = 60 km/h \: \blue \bigstar}[/tex]

[tex] \bf\frac{1}{y} = b \\ \\ \bf \red {b = 80 km/h \: \pink \bigstar} [/tex]

Hence, the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr.

Question:

Haydin chooses a jersey at random and then replaces it. He then selects a second jersey at random. What is the probability that Haydin selects a striped jersey both times. 2 are striped,5 are colored and 3 are white.

Answer:

[tex]Probability = 0.04[/tex]

Step-by-step explanation:

Given

[tex]Striped = 2[/tex]

[tex]Colored = 5[/tex]

[tex]White = 3[/tex]

Required

Determine the probability that both selections are stripped

This is calculated as:

[tex]Probability = P(Stripped) * P(Stripped)[/tex]

[tex]Probability = \frac{n(Stripped)}{Total} * \frac{n(Stripped)}{Total}[/tex]

[tex]Probability = \frac{2}{2 + 5 + 3}* \frac{2}{2 + 5 + 3}[/tex]

[tex]Probability = \frac{2}{10}* \frac{2}{10}[/tex]

[tex]Probability = \frac{4}{100}[/tex]

[tex]Probability = 0.04[/tex]

Answer:

8 inches

Step-by-step explanation:

Given that:

Rate of Snow accumulation = [tex]\frac{4}{5}\ in/hr[/tex]

Time for which the snow gets accumulated at the same rate = 10 hours

To find:

How much snow will get accumulated if the snow keeps accumulating at the same rate ?

Solution:

To get the amount of snow that got accumulated, we need to multiply the rate of snow accumulation with the time for which the snow kept on accumulating.

Formula:

Amount of snow accumulated = Rate of snow accumulation [tex]\times[/tex] Time taken for snow accumulation

[tex]\Rightarrow \dfrac{4}{5}\times 10\\\Rightarrow 4\times 2\\\Rightarrow \bold{8\ inches}[/tex]

Therefore, 8 inches of snow got accumulated.

Answer:

16 flowers per bouquet

Step-by-step explanation:

if you try to solve this question using the given equations the answer will not make a lot of sense:

y = 24 - 1x

128 = 24 - 7x

-7x = 128 - 24 = 104

x = 104 / -7 = -14.86 flowers

the equation is not correct, it should be:

y = 240 - 1x

128 = 240 - 7x

7x = 240 - 128 = 112

x = 112 / 7 = 16 flowers per bouquet

'a' is parallel to 'b' because both agree with the same - side exterior theorem

It states that when two parallel lines are cut by a third intersecting line (transversal line), eight angles are formed and these angles form different relationships with each other, called same-side exterior.

Same-side tells us that exterior tells us that both angles are exterior, or outside, of the parallel lines.

In the figure, angles a, b, c, and d are exterior to the parallel lines.

We can then say that;

a is parallel to b because both agree with the same - side exterior theorem

Hence, 'a' is parallel to 'b' because both agree with the same - side exterior theorem
