If ax^3+bx^2+x-6 has (x+2) as a factor and leaves a remainder 4 when divided by (x-2), find the value of a and b

Answers

Answer 1

Answer:

a = 0

b = 2

Step-by-step explanation:

Synthetic division gives rise to two equations:

b -2a = 2

b +2a = 2

The solution to these equations is (a, b) = (0, 2).

___

The remainder from the division is the lower-right sum shown in the attached tables. For the factor x+2, the remainder from dividing your cubic by x+2 is (4b-8a-8). Setting this to zero and putting it into standard form gives the first equation shown above.

The remainder from division by (x-2) is (4b+8a-4). Setting this to 4 and putting the result into standard form gives the second equation above.

What is the sum of the arithmetic sequence 8, 14, 20 ..., if there are 22 terms?

Answers

Answer: I'm pretty sure its 1562

Answer:

The sum of 22 terms of given AP = 1562

Step-by-step explanation:

Formula:-

Sum of n terms of AP,

Sₙ= (n/2)[2a + (n - 1)d]

To find the sum of 22 terms

Here. a = 8, d = 6 and n = 22

Sₙ= (n/2)[2a + (n - 1)d]

S₂₂ = (22/2)[2*8 + (22 - 1)*6]

Which statements describe the solutions to (√x-2)-4=x-6? Check all that apply.

There are no true solutions to the radical equation.
x = 2 is an extraneous solution.
x = 3 is a true solution.
There is only 1 true solution to the equation.
The zeros of 0 = x2 – 5x + 6 are possible solutions to the radical equation.

Answers

Answer:

x = 3 is a true solution.

The zeros of 0 = x2 – 5x + 6 are possible solutions to the radical equation.

Step-by-step explanation:

Given in the question an equation,

√(x-2) - 4 = x - 6

√(x-2) = x - 6 + 4

√(x-2) = x -2

Take square on both sides of the equation

√(x-2)² = (x -2)²

x - 2 = x² - 4x + 4

0 = x² - 4x - x + 4 + 2

0  = x² - 5x + 6

a = 1

b = -5

c = 6

x = -b±√(b²-4ac) / 2a

x = -(-5)±√(5²-4(1)(6)) / 2(1)

x = 5 ± √1 / 2

x = 5 + 1 / 2 or  5 - 1 /2

x = 3 or x = 2

Plug value of x in the radical equation:

x=3

√(3-2)-4=3-6

√1 -4 = -3

 1 - 4 = -3

    -3 = -3

x=2

√(2-2)-4=2-6

0 - 4 = -4

    -4 = -4

C. x = 3 is a true solution.

what relationship has a zero slope

Answers

Answer:

the far left table

Final answer:

In Mathematics, a zero slope represents a horizontal line that can be defined by the equation y = C, where C is a constant, showing no relationship between changes in x and y.

Explanation:

In Mathematics, when discussing about slopes, a zero slope signifies that there is no change in y for any change in x. This results in a straight horizontal line when graphed. A real-life example might be that if you were walking on a flat road, the slope of that road is zero because your altitude isn't changing no matter how far you walk horizontally.

The relationship involved in a zero slope scenario can be defined by the equation y = C, where C is a constant. This means that y will remain constant despite any changes in x.

The equation of a line with zero slope can be declared as y = b, where b is the y-intercept. This shows no correlation between x and y as x varies but y remains constant.

A youth soccer association raised ​$5145 in​ fund-raising projects. There were expenses of ​$777 that had to be paid​ first, with the balance of the money divided evenly among the 14 teams. How much did each team​ receive?

Answers

Answer:

Each team recieved $312

Step-by-step explanation:

You will take $5145 - 777 = 4368 which is the balance

4368 of the balance  ÷ 14 teams =312

each team received  $312

Final answer:

After paying the expenses of $777 from the fund-raising total of $5145, $4368 was left. When this amount was divided evenly amongst 14 soccer teams, each team received $312.

Explanation:

To solve the problem, we first need to subtract the expenses from the total fund-raising amount. This gives us $5145 - $777 = $4368.

After the expenses are taken into consideration, the remaining money is divided evenly among the 14 soccer teams. This is calculated by taking the remaining money and dividing it by the number of teams, $4368 ÷ 14 = $312.

So, each team will receive $312 after all the expenses are paid.

If f(x)=5x-25 and g(x)=1/5x+5, which expression could be used to verify g(x) is the inverse of f(x)?

Answers

Final answer:

The expression to verify that g(x) is the inverse of f(x) is to check if f(g(x)) = x and g(f(x)) = x. When we calculate both expressions for the given functions, they both simplify to x, which confirms that g(x) is the inverse of f(x).

Explanation:

To verify that g(x) is the inverse of f(x), we need to show that composing f with g yields the identity function. In other words, f(g(x)) should equal x, and vice versa, g(f(x)) should also equal x. For the given functions, f(x) = 5x - 25 and g(x) = 1/5x + 5, let's compute f(g(x)) and g(f(x)).

To find f(g(x)), we substitute g(x) into f(x):

f(g(x)) = f(1/5x + 5) = 5(1/5x + 5) - 25 = x + 25 - 25 = x

Next, to find g(f(x)), we substitute f(x) into g(x):

g(f(x)) = g(5x - 25) = 1/5(5x - 25) + 5 = x - 5 + 5 = x

Since both f(g(x)) and g(f(x)) equal x, we can conclude that g(x) is indeed the inverse of f(x).

Can somebody teach me inscribed angles! My 40 question summarize on circles in geometry is today and I need help on everything! ​

Answers

Inscribed angles are pretty easy, they're always half the corresponding central angle.  The arc measure are always of central angles.

1. We're told to arc is 62 degrees so the inscribed angle is half,

WXY = 31 degrees.

2. Here we're told the inscribed angle is 113 degrees so the arc is double,

DGF=226 degrees

3. Angles which subtend a diameter are always right angles.

PQR = 90 degrees

4. If we draw DC we see it's a radius too, so DC=DB and we have an isosceles triangle so DCB=47 degrees so BDC=180-47-47=86.  The central angle is the arc measure so

BC=86 degrees

5. Angle JNK=53 degrees and angles NJK=NKJ because we have an isosceles triangle, two sides radii.  So NKJ=(180-53)/2.

Similarly NKL=(180-65)/2

So angle JKL=NKJ+NKL=180 - (65+53)/2 = 180 - 118/2 = 121 degrees

I better leave the rest for you.

Final answer:

An inscribed angle is formed by two secant lines intersecting on a circle's circumference and is half the measure of the central angle intercepting the same arc. Fundamental theorems like the Pythagorean theorem and mnemonic SOHCAHTOA are important in geometry, especially when dealing with circles and triangles.

Explanation:

An inscribed angle is formed when two secant lines of a circle intersect on the circle's circumference. The value of an inscribed angle is always half the measure of the central angle that intercepts the same arc.

This is a foundational concept in geometry that is often linked to other geometric properties and theorems, such as the relationship between angles and arcs, and the behavior of angles within and outside of circles.

Knowing how to work with inscribed angles is crucial, particularly when dealing with problems involving circles.

For example, if you know the measure of the central angle, you can easily find the inscribed angle by dividing the central angle by 2. Recall other basic geometrical facts, such as the Pythagorean theorem, which states that in a right triangle, a² + b² = c² (where c is the hypotenuse), and the mnemonic SOHCAHTOA which helps remember the relationships of sides and angles in right triangles.

To help visualize these concepts, sketching triangles and remembering that the angles of a triangle sum up to 180 degrees can be helpful. Plane geometry forms the basis for understanding these principles, which is essential in tackling more advanced problems in circles and other geometric figures.
