Answer:

6.64 seconds

Step-by-step explanation:

Given that:

Distance between roof of the terminal and ground = 709 feet

A bucket was dropped from the roof.

To find:

The time taken by the bucket to hit the ground?

Solution:

Distance traveled, [tex]s[/tex] = 709 feet

Initial velocity of the bucket, [tex]u[/tex] = 0 feet/sec (because initially it was at rest)

Acceleration of the bucket will be equal to acceleration due to gravity i.e.

[tex]g[/tex] or 32.1741 [tex]ft/sec^{2}[/tex]

Let the time taken is [tex]t[/tex] seconds.

Formula for distance is given as:

[tex]s = ut+\dfrac{1}{2}at^2[/tex]

Putting all the values:

[tex]709 = 0 (t) + \dfrac{1}{2}(32.1741) t^2\\\Rightarrow 1418 = 32.1741 t^2\\\Rightarrow t^2 = 44.07\\\Rightarrow t \approx \bold{6.64\ sec}[/tex]

Answer:

71 degrees

Step-by-step explanation:

The sum of the angles in a triangle is 180.

180 - 24 - 85 = 71.

The required measure of the remaining angle would be 71°

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbol. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

A triangle has angle measurements of 24º and 85° which is given in the question.

The linear pair of angles are adjacent angles the sum of their measures is 180°

∵ The two angles form a linear pair

∴ The sum of the two angles = 180°

Let the measure of the remaining angle would be x

⇒ 24° + 85°  + x = 180°

⇒ x = 180 - 24° - 85°

⇒ x = 71°.

Therefore, the required measure of the remaining angle would be 71°

Step-by-step explanation:

When a star begins to run out of fuel, the first thing that happens is that the star’s core shrinks.

Option A is the correct answer.

In the context of an automobile, the term "core" usually refers to a component of a vehicle's cooling system called the radiator core.

The radiator core is responsible for dissipating heat from the engine coolant by allowing air to flow through a series of metal fins attached to narrow tubes that carry the coolant.

We have,

When a star begins to run out of fuel, the first thing that happens is that the star’s core shrinks.

This is because the energy produced by nuclear fusion reactions in the core of the star is what keeps the star from collapsing under its own gravity.

As the fuel for these reactions runs out, the core of the star no longer has enough energy to counteract the force of gravity, causing it to shrink.

This in turn causes the outer layers of the star to expand, leading to the next stage in the star’s life cycle.

Thus,

The star’s core shrinks.

Answer:

The equation of the line with slope 6 and containing the point (0, 4) will be:

[tex]y = 6x+4[/tex]

The graph of the line y = 6x+4 is attached below.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given

The y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

The point (0, 4) indicates that:

at x = 0, y = 4

Thus, the y-intercept b = 4

now substituting b = 4 and m = 6 in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y = 6x+4[/tex]

Thus, the equation of the line with slope 6 and containing the point (0, 4) will be:

[tex]y = 6x+4[/tex]

The graph of the line y = 6x+4 is attached below.

Answer:

B. The rate of change is 2.

C. The rate of change is constant.

D. The rate of change is increasing.

Step-by-step explanation:

Rate of change over 1.5 ≤ x ≤ 3:

[tex] rate of change = \frac{f(b) - f(a)}{b - a} [/tex]

Where,

a = 1.5, f(a) = 1,

b = 3, f(b) = 4

Plug in the values:

[tex] rate of change = \frac{4 - 1}{3 - 1.5} = \frac{3}{1.5} = 2 [/tex]

✔️The rate of change = 2

✔️The rate of change is increasing because the value is a positive value.

✔️The rate of change is also constant over 1.5 ≤ x ≤ 3 since the line is straight.

The points on the interval of the absolute value function in the graph are on the same straight line.

The statements that describe the rate of change over the interval; 1.5 ≤ x ≤ 3 are;

Reasons:

The given parameter of the graph of the f are;

The vertex of the function = (1, 0)

The straight line of the function f passes through the points (1.5, 1) and (3, 4)

Therefore;

[tex]\displaystyle The \ slope \ of \ the \ graph \ between \ (1.5, \, 1) \ and \ (3, \, 4) = \mathbf{\frac{4 - 1}{3 - 1.5} }= \frac{3}{1.5} =2[/tex]

The slope of the graph = The rate of change of the graph

Therefore;

The rate of change of the graph over the interval 1.5 ≤ x ≤ 3 is 2

Given that the graph is a straight line graph, we have;

The slope of the graph is constant, therefore;

The total bill for servicing her car will be £112.8

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Mrs. Browns bill for servicing her car is £96 plus VAT.

And, VAT is charged at 17.5%.

Now,

Since, VAT is charged at 17.5%.

So, The VAT charge = 17.5% of £96

                                = 17.5 / 100 x £96

                                = £16.8

Hence, The total bill for servicing her car = £96 + £16.8

                                                                = £112.8

Thus, The total bill for servicing her car will be £112.8

Answer: A and C

Step-by-step explanation:

Point A and C is true about the coordinate plane.

Given that, Mallory is investigating transformations in the coordinate plane.

A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called the y-axis and a horizontal line called the x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin.

A) A reflection over the y-axis takes the point (x, y) to (-x, y)

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

B) A reflection over the line y = -x takes the point (x, y) to (x, y)

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

C) A translation of 4 units down takes the point (x, y) to (x, y - 4)

For example, to translate a point 1 unit to the left and 4 units down, subtract 1 from the x -value and subtract 4 from the y -value.

D) A rotation of 180° clockwise about the origin takes the point (x, y) to (y, -x).

The rule for a rotation by 180° about the origin is (x, y) → (−x, −y).

Therefore, point A and C is true about the coordinate plane.

Answer:

y=-5x+1

Step-by-step explanation:

First lets identify what slope intercept form looks like:

y=mx+b

m=slope

b=y-intercept

the y-intercept would be at (0,1)

choose 2 points from the graph and lets find the slope.

The formula for slope is:

[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex]

The points we will be using will be (1,-4) and (2,-9)

so -9 will be [tex]y_{2}[/tex] and -4 is [tex]y_{1}[/tex]

2 is [tex]x_{2\\}[/tex] and 1 is [tex]x_{1}[/tex]

set up the equation.

[tex]\frac{-9-(-4)}{2-1}[/tex]

[tex]\frac{-5}{1}[/tex]

m = -5

So the slope is -5 and the y-intercept is 1

[To find the y-intercept all you have to do is find what y is counting by. In this is would be -5. Go backwards one on the table so x is 0 and take away -5 and it will give you 1 which would be the intercept]

So the equation will be

y=-5x+1

Now when you want to solve it you plug in the x and y values for the table but it doesn't ask you to do that,
