Using the angle theorems, the measure of angle 6, m ∠6, is 54°

From the question, we are to determine the measure of angle 6

From the given diagram, we can write that

(13x + 9)° = m ∠5 (Corresponding angles theorem)

and

m ∠5 + (5x + 9)° = 180° (Linear pair theorem)

Thus,

(13x + 9)°  + (5x + 9)° = 180°

Now, we will solve for x

13x + 9 + 5x + 9 = 180

18x + 18 = 180

Subtract 18 from both sides of the equation

18x + 18 - 18 = 180 - 18

18x = 162

x = 162/18

x = 9

Now, to determine the measure of angle 6

m ∠6 = (5x + 9)° (Vertical angles theorem)

Substitute the value of x

m ∠6 = (5(9) + 9)°

m ∠6 = (45 + 9)°

m ∠6 = 54°

Hence, measure of ∠6 is 54°

Perfect square trinomials are algebraic expressions with three terms that are obtained by multiplying a binomial with the same binomial. A perfect square is a number that is obtained by multiplying a number by itself. Binomials are algebraic expressions consisting of just two terms that are either separated by a positive (+) or a negative (-) sign. Similarly, trinomials are algebraic expressions consisting of three terms. When a binomial consisting of a variable and a constant is multiplied by itself, it results in a perfect square trinomial having three terms. The terms of a perfect square trinomial are separated by either a positive or a negative sign.

A perfect square trinomial is defined as an algebraic expression that is obtained by squaring a binomial expression. It is of the form [tex]ax^{2} +bx+c[/tex]. Here a, b, and c are real numbers and a ≠ 0. For example, let us take a binomial (x+4) and multiply it to (x+4). The result obtained is [tex]x^{2} +8x+16[/tex]. A perfect square trinomial can be decomposed into two binomials and the binomials when multiplied with each other gives the perfect square trinomial.

Answer:

m arcRP = 125°

m arcQS = 125°

m arcSP = 55°

m arcQR = 55°

Step-by-step explanation:

An arc is the curve between two points on the circumference of a circle.

An arc measure equals its corresponding central angle measure.

Vertical Angles Theorem:  When two straight lines intersect, the opposite vertical angles are congruent.

Angles on a Straight Line Theorem:  The sum of angles formed on a straight line is equal to 180°.

As m∠ROP = 125°

Therefore, m arcRP = 125°

Given the measure of angle ROP is 125°, and an arc measure equals its corresponding central angle measure, the measure of arc RP is 125°.

Using the Vertical Angles Theorem:

⇒ m∠QOS = 125°

Therefore, m arcQS = 125°

Using the Vertical Angles Theorem, the measure of angle QOS is equal to the measure of angle ROP, so the measure of angle QOS is 125°. As an arc measure equals its corresponding central angle measure, the measure of arc QS is 125°.

Using the Angles on a Straight Line Theorem:

⇒ m∠SOP = 180° - 125° = 55°

Therefore, m arcSP = 55°

Using the Angles on a Straight Line Theorem, the measure of angle SOP is 55°. As an arc measure equals its corresponding central angle measure, the measure of arc SP is 55°.

Using the Angles on a Straight Line Theorem:

⇒ m∠QOR = 180° - 125° = 55°

Therefore, m arcQR = 55°

Using the Angles on a Straight Line Theorem, the measure of angle QOR is 55°. As an arc measure equals its corresponding central angle measure, the measure of arc QR is 55°.

===================================================

Explanation:

The car is initially worth 44000 pounds.

It loses 25% of its value after the first year, but keeps the remaining 75% of it.

75% of 44000 = 0.75*44000 = 33000

The car is worth 33000 pounds at the end of year 1. This is effectively the "starting" value when we change the rate of depreciation.

------------------

The new percentage of the depreciation rate is x%

The car loses x% of its value each year

But it keeps the remaining (100-x)% of the value from year to year. Refer to the previous section.

x% = x/100

(100-x)% = (100-x)/100 = 100/100 - x/100 = 1 - 0.01x

The 1 - 0.01x is the value of b in the exponential equation y = a*b^t

The value of 'a' is the "starting" value of 33000 pounds.

The t represents the number of years after that first year (so that means we have t+1 years total).

The equation we have is

y = a*b^t

y = 33000(1 - 0.01x)^t

The teacher mentions "after 3 years" which means we'll have t+1 = 3 solve to t = 2 which is what we'll plug in along with  y = 25555

Let's solve for x.

y = 33000(1 - 0.01x)^t

25555 = 33000(1 - 0.01x)^2

25555/33000 = (1 - 0.01x)^2

0.77439393939393 = (1 - 0.01x)^2

(1 - 0.01x)^2 = 0.77439393939393

1 - 0.01x = sqrt(0.77439393939393)

1 - 0.01x = 0.87999655646709

-0.01x = 0.87999655646709-1

-0.01x = -0.1200034435329

x = -0.1200034435329/(-0.01)

x = 12.00034435329

Due to rounding error, it appears that it should be x = 12 since your teacher mentions x is an integer.

Also, 12.00034435329 is pretty close to 12.

If it decays at 12% per year, then the car keeps the remaining 88% since 100-12 = 88

Therefore 0.88 is the base of the exponential, it's the value of b.

Computing 33000(0.88)^2 gets us 25,555.2 which isn't too far from the goal of 25,555 pounds.

------------------

We found the exponential decay equation to be

y = 33000(0.88)^t

where t is the number of years after that first year. We have t+1 years total.

Your teacher asks how much the car will be worth after 4 years, so we'll plug in t = 3 because it's the solution to t+1 = 4.

In other words, we're working 3 years after that first year is up, so 3+1 = 4 total years.

Plug in t = 3 to find the following

y = 33000(0.88)^t

y = 33000(0.88)^3

y = 22,488.576

Rounding to the nearest pence gets us 22,489.58 which is the value of the car after 4 years. You can verify this with a spreadsheet table as I have shown in the diagram below. The highlighted rows mention values on your screenshot.

I'll round to the nearest pound since the other car values mentioned were whole numbers rather than decimal ones.

The 22489.58 rounds to 22490

------------------

For the final part, we'll need logarithms to solve the equation. Logarithms are useful to isolate the exponent.

We'll plug in y = 14520 and solve for t

y = 33000(0.88)^t

14520 = 33000(0.88)^t

14520/33000 = (0.88)^t

0.44 = (0.88)^t

Log[ 0.88^t ] = Log[ 0.44 ]

t*Log[ 0.88 ] = Log[ 0.44 ]

t = Log[ 0.44 ]/Log[ 0.88 ]

t = 6.42227097958021

This rounds up to t = 7

Round up instead of down because we want to clear the hurdle of passing the 14520 marker.

Recall once again that t is the number of years after the first year.

So t = 7 represents t+1 = 7+1 = 8 years in total that have passed by. Therefore, after 8 years is when the car's value is below 14520 pounds. Refer to the table diagram below.

Only height, because when you have an expression that relies only on multiplication (not addition or subtraction), we'll say:

cb = a

Tripling either c or b will also triple a. For example:

(8)(3) = 24

(8 + 8 + 8)(3) = 24(3)
(24)(3) = 24(3)

This will be true even if you multiply c by any other number.

So, in the expression v = πr²h, any term except r can be tripled with the result of tripling v. We exclude r because r has an exponent, which means tripling r will more than triple v.

The value of the net force acting on the block will be equal to 79N.

Force may be defined as the product of mass and acceleration, and it acts on the body in order to move the body. Since, the external force is acting on the block there will be a frictional force which opposes the block to move. The frictional force may be represented by f(k) and is given by

f(k) = external force - (ma)

f(k) = 40N - (5×6)

f(k) = 40N - 30N

f(k) = 10N and since it opposes the external force then the sign will be negative that is f(k) = -10N.

Also, there is a force of gravity acting on the body which will be equal to mg where 'g' is the acceleration due to gravity.

Now, force of gravity = mg

= 5×9.8 = 49N

Now, net force acting on the block = 40N - 10N + 49N
