The value of x to the nearest tenth by the Pythagoras theorem is 6.57.

It is given that

Length of the chord = 11

Distance of chord from the center of the circle = 3.6

As we know that perpendicular drawn from the center of a circle to its chord bisects the chord.

Using Pythagoras theorem

The square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

[tex]x^{2} = 3.6^{2} + (11/2)^{2}[/tex]

[tex]x^{2} = 12.96 + 30.25\\\\x^{2} = 43.21\\\\x = 6.57[/tex]

Therefore, the value of x to the nearest tenth is 6.57.

Answer:

The correct answer would be option C, $435

Explanation:

In real financial banking transactions, Debits are basically the withdrawals and credits are deposits.  

Because the problem states that there was an over withdrawal on Thursday but not on Saturday, this means that the ending balance on Thursday was a negative balance. On Saturday, the remaining balance was a positive balance. 500 and 480 as a beginning balance doesn't give a negative balance on Thursday. 400 as a beginning balance gives a negative balance on Thursday as well as Saturday.

Answer:

(- 5, 4)

Step-by-step explanation:

Under a reflection in the line y = x

a point (x, y) → (y, x)

Hence

G(4, - 5) → G'(- 5, 4)

If the vertex G is reflected across the line y= x, the resulting coordinate will be (-5, 4)

Reflection creates a mirror image of each other. If the coordinate (x, y) are reflected across the line y = x, the resulting coordinate is (y, x)

Given the coordinate G(4, -5). If the vertex G is reflected across the line y= x, the resulting coordinate will be:

G(4, -5) = G'(-5, 4)

Note that the coordinate points are only interrchanged

For this case we have by definition that if two lines are parallel, then their slopes are equal.

We have the following line:

[tex]-2x + 4y = 8[/tex]

Manipulating algebraically we have:

[tex]4y = 8 + 2x[/tex]

[tex]y = \frac {2x} {4} + \frac {8} {4}\\y = \frac {1} {2} x + 2[/tex]

Thus, the slope is [tex]m = \frac {1} {2}[/tex]

Then, a parallel line will be of the form:

[tex]y = \frac {1} {2} x + b[/tex]

We find the cut point "b" replacing the point:

Answer:

The best prediction for the number of questions that Amit will answer correctly is 5.

Step-by-step explanation:

Each question can be considered as an independent Bernoulli trial. This implies that we have 20 independent trials.

Now, the probability of making a correct guess on each question is;

1/4. This is because we have 4 choices per question and only 1 is correct.

If we now let the random variable X denote the number of questions that Amit will answer correctly, then X is a Binomial random variable with parameters;

20 and 1/4.

The expected number of correct answers is simply the product of these two values;

20 * (1/4) = 5

Therefore, the best prediction for the number of questions that Amit will answer correctly is 5

Answer:

A. 10%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

The new number is the increased wage, $8.25, and the old number is the original wage, $7.50.

percent change = ($8.25 - $7.50)/($7.50) * 100%

percent change = ($0.75)/($7.50) * 100%

percent change = 0.1 * 100%

percent change = 10%

Since the percent change is a positive number, it is a percent increase.

The percent increase was 10%.

Answer: A. 10%

Answer:

-8

Step-by-step explanation:

When you factor, you just find two numbers that add to be the first number (16) and multiply to be the second number (64). 8 and 8 both do this. So when we factor, we also add the variable into each equation because it also has been divided into two equations, and we get: (p + 8)(p +8). Notice that the equations are "+8" and not "-8" because two +8s add to give us a +16 and multiply to give us a +64. After that, we just solve the two equations to find the solutions. Subtract 8 from each equation (we do the opposite operation because 8 is positive) to get -8. Because the answer for each equation is the same our answer is -8.

Answer:

That factors into:

(p +8) * (p +8) =0

Therefore, p = -8 and p = -8

i) An intersecting system of linear equations

A system of linear equations comprises of two or more linear equations. Linear equations are simply straight line equations with a given slope and a unique y-intercept .

Solutions to systems of linear equations can be determined using a number of techniques among them being;

Elimination method

Substitution method

Graphical method

The graphs of a system of linear equations will intersect at a unique single point if the lines are not parallel.

An example of intersecting system of linear equations;

y = 2x -5 and y =5x + 4

The two lines will intersect at a particular single point since the slopes are not identical. The attachment below demonstrates this aspect.

ii) A parallel system of linear equations

Two lines are said to be parallel if they have an identical slope but unique y-intercepts. Parallel lines never intersect at any given point since the perpendicular distance between them is always constant.

Thus a parallel system of linear equations has no solution. An example of parallel system of linear equations;

y = 3x - 4 and y = 3x + 8

The attachment below demonstrates this aspect.

iii) A coincident system of linear equations

A system of linear equations is said to be coincident if the two straight lines are identical. That is the lines have an identical slope and y-intercept. Basically, we are just looking at the same line. Two parallel lines can also intersect if they are coincident, which means they are the same line and they intersect at every point.

Therefore, this system of linear equations will have an infinite number of solutions.

Answer:

150 sheets is the better buy.

Step-by-step explanation:

Cost of each sheet when buying 100 = $2.50 / 100 = $0.0250'

If you buy 150 cost per sheet =  $3.50 / 150 = $0.0233.....

So buying 150 sheets is the better buy.

Final answer:

After calculating the unit price for both options, the 150 sheets at $3.50 offer a lower unit price of approximately $0.0233 per sheet compared to $0.025 per sheet for 100 sheets at $2.50, making it the better buy.

Explanation:

To determine which is a better buy between 100 sheets of binder paper at $2.50 and 150 sheets at $3.50, we need to calculate the unit price for each option.

Comparing the two unit prices, the 150 sheets at $3.50 offer a lower unit price and thus represent a better value for your money.

y = 4t - 5

Step-by-step explanation:

To find a set of parametric equations for the line y = 4x - 5;

We can assign either variable x or y equal to the parameter t, in this case we can easily let x = t

We then substitute x = t in the original equation;

y = 4t - 5

Therefore, a set of parametric equations for the line y = 4x - 5 is;

x = t

y = 4t - 5

Answer:

One solution graph is when the graphs of the equations intersect, then there is one solution that is true for both equations.  

One solution = lines intersect

No solution graph is when the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.

No solution: lines are parallel

Infinitive solution graph is when the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

Infinitive solutions: One line

Since

[tex]\csc(x)=\dfrac{1}{\sin(x)}[/tex]

we have

[tex]\csc(x)\sin(x)+\tan(x) = \dfrac{1}{\sin(x)}\cdot \sin(x)+\tan(x)=1+\tan(x)[/tex]

And since

[tex]\tan(x)=\dfrac{8}{15}[/tex]

we have

[tex]1+\tan(x) = 1-\dfrac{8}{15}=\dfrac{15}{15}-\dfrac{8}{15}=\dfrac{7}{15}[/tex]

The value of cscθ sinθ + tan θ is 7/15.

cscθ is the reciprocal of sinθ.

The expression is given by cscθ sinθ + tan θ.

We can simplify this expression before solving it.

Let the expression be y = cscθ sinθ + tan θ.

cscθ = 1/sinθ

y = sinθ * 1/sinθ + tan θ

y = 1 + tan θ

The value of tan θ is given as -8/15.

We can substitute this above:

y = 1 + tan θ

= 1 - 8/15

= (15-8)/15

= 7/15

The value of the expression cscθ sinθ+ tan θ is found to be 7/15.

Therefore, the value of cscθ sinθ + tan θ is 7/15.
