The New book value for Old piece Equipment is RM30, 000.

Depreciation is an accounting technique for spreading out the expense of a tangible item over the course of its useful life. How much of an asset's value has been used is shown through depreciation. It enables businesses to purchase assets over a predetermined length of time and generate income from those assets.

Given:

We know

Net Book Value = Original Asset Cost – Accumulated Depreciation.

Accumulated Depreciation

=  5000 x 5

= 25000

Net Book Value = $55000– $25000= $30000

Hence, the New book value for Old piece Equipment is RM30, 000.

Answer:

c. o.5seconds

Step-by-step explanation:

y=-16t^2 +4t+2

=-2(8t^2 -2t-1)

=-2(8t^2 -4t+2t-1)

as the object hits the ground y =0

0 =-2(4t+1)(2t-1)

(4t+1)(2t-1)=0

t=-1/4 meangless

t=1/2

The time at which the object hit the ground is 0.5 second.

The correct option is (C).

A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .

Given:

y= -16t² +4t+2

Now, the time at which the object hit the ground

y = 0

-16t² +4t+2 = 0

-2(8t² -2t-1) = 0

8t² -2t-1 = 0

8t² -4t + 2t -1 = 0

(4t+1)(2t-1) = 0

So, 4t+ 1= 0 or 2t- 1=0

t= -1/4 or t = 1/2.

Hence, the object will hit the ground at t= 0.5 second.

The missing term of the given arithmetic series is A)10.25

What is arithmetic series?

The sum of a sequence in which each term is calculated from the preceding one by adding (or removing) a constant is known as an arithmetic series.

An arithmetic sequence is added to create an arithmetic series. 3, 7, 11, 15, and 19 are examples of an arithmetic sequence. This is an infinite series, as indicated by the ellipses at the end. There is a 4. common difference. Simply add the entries from the sequence to make it an arithmetic series: 3 + 7 + 11 + 15 + 19 +...

Here the given series is arithmetic series,

First term a1= 19.75

Here common difference = a2-a1=15-19.75=-4.75

Similarly third term a3= 15-4.75 = 10.25

Fourth term a4 = 10.25-4.75=5.5

Fifth term a5=5.5-4.75=.75

Hence the missing term of the series is option A) 10.25

The correct answer is d.  The standard form of the equation of f(x) is −x2 + 6x + 16.

A downward opening parabola is a curve in the shape of a parabola that opens downward and is symmetrical about the x-axis. The equation of a downward opening parabola is y = ax^2 + bx + c, where a is a negative number, and b and c are constants.

The focus of a downward opening parabola is the point on the parabola where the curvature is greatest and is located at the vertex of the parabola.

The directrix of a downward opening parabola is a line parallel to the x-axis and the distance from the focus to the directrix is equal to the length of the latus rectum of the parabola. The equation of the directrix is y = -a(x - h)^2 + k, where h and k are constants.

Downward opening parabolas can be used to graphically represent any type of data that follows a parabolic shape. This includes physical phenomena such as the path of a projectile or the vibration of a string.

Downward opening parabolas can also be used to model economic or financial data, such as the demand for a product or the price of a commodity. They may also be used to describe relationships between two variables in a mathematical equation.

The standard form of a parabola equation is f(x) = ax2 + bx + c, where a, b, and c are real numbers. In this case, the vertex of the parabola is at (3, 25), so the equation is in the form f(x) = a(x - 3)2 + 25. Putting in the other points on the graph to solve for a, b, and c yields the equation f(x) = -x2 + 6x + 16.

Answer:

2.275%

Step-by-step explanation:

We solve this question using z score formula

z = (x-μ)/σ,

where

x is the raw score = 70 mph

μ is the population mean = 100 mph

σ is the population standard deviation = 15 mph

z score = 70 - 100/15

z score = -30/15

z score = - 2

Determining the Probability value from Z-Table:

P(x ≤ 70) = P(x < 70)

= P(z = -2)

= 0.02275

Hence the probability of the player's serve that are less than 70 mph is 0.02275

Converting it to percentage

= 0.02275 × 100

= 2.275%

Therefore, the percentage of the player's serve speeds that are less than 70 mph is = 2.275%

Yes, Josh has enough information to find how far he is from the picnic table.  Josh is 90.1 ft from the picnic table (to the nearest tenth).

Step-by-step explanation:

Yes, Josh has enough information to find how far he is from the picnic table.

From the given information, we can model this as a right triangle where the angle is 54°, the side opposite the angle is the distance between the picnic table and the tree, and the side adjacent the angle is the distance between Josh and the picnic table. (See attached diagram).

To calculate the distance between Josh and the picnic table (labelled "x" on the attached diagram), use the tangent trigonometric ratio.

\(\boxed{\begin{minipage}{6 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\end{minipage}}\)

Substitute the values into the tan ratio:

\(\implies \tan 54^{\circ}=\dfrac{124}{x}\)

\(\implies x=\dfrac{124}{\tan 54^{\circ}}\)

\(\implies x=90.09127...\)

\(\implies x=90.1\; \sf ft\;(nearest\;tenth)\)

Therefore, Josh is 90.1 ft from the picnic table (to the nearest tenth).

Alijah's taxable income puts him in the first tax bracket, over $8,350 but not surpassing $33,950. Hence, his tax due is a base of $835 plus 15% of the income that exceeds $8,350. This results in a total tax payable of $850. Option B is the correct answer.

Alijah's taxable income falls within the first bracket of the tax table given, being over $8,350 but not over $33,950.

This bracket requires him to pay a tax of $835.00 plus 15% of the amount over $8,350.

He has a surplus of $100 over the $8,350 threshold (i.e., $8,450 - $8,350), and 15% of $100 equals $15.

Therefore, the total tax he owes would be the fixed amount of $835.00 plus the $15.00 calculated, which sums up to $850.00.

Thus, looking at the provided options, option B ($850.00) would be the correct answer.

What is Free Throw Percentage?

Free throw percentage (FT%) puts a player’s successful free throws in perspective to their total attempts.

In basketball, a free throw (or foul shot) is awarded to a player who has been fouled by the other team. The number of free throws depends on where on the court the player was while being fouled.

To find 1% of a number, we can move the decimal point of the number two places to the left.

Therefore, 1% of 120 is 1.2

To find 10% of a number, we can move the decimal point of the number one place to the left.

Therefore, 10% of 120 is 12

Since 10% of 120 is 12 and

20% = 2 x 10%

then 20% of 120 = 2 x 10% of 120

= 2 x 12 = 24

Since 1% of 120 is 1.2 and

8% = 8 x 1%

then 8% of 120 = 8 x 1%  of 120
