Find a polynomial function p which satisfies following criteria?

Mathematics
1 answer:
Schach [20]3 years ago
7 0

Answer:

p(x) has a double root at x = -4, and

a single root at x = 6. So the polynomial

has the form p(x) = a(x + 4)^2(x - 6) = ax^3 + . . . - 96a

But since p(x) ---> ∞ as x ---> - ∞ and ---> -∞ as x ---> ∞,

a must be < 0. That, together with the fact that p(0) = 1,

means a = - 1 / 96. So, p(x) = (- 1 / 96)(x + 4)^2(x - 6)

Three fifths of a number, plus 8, is equal to the number.What is the number?
Luden [163]

Answer:

The number is 20.

Step-by-step explanation:

To solve this, first take the words and turn into an equation.

3/5x + 8 = x

Now we can solve for x using the order of operations

3/5x + 8 = x

8 = 2/5x

20 = x

Answer:

(a) x = 128^{o}

(b) x = 74^{o}

Step-by-step explanation:

A. sum of angles in a polygon = (n - 2) 180

The polygon given is an irregular pentagon, where n = 5

So that;

sum of angles in a pentagon = (5 - 2) 180

                        = 3 x 180

                        = 540^{o}

Thus,

x + 90 + 76 + 110 + 136 = 540^{o}

x + 412 = 540^{o}

x = 540^{o} - 412

x = 128^{o}

B. The polygon given is an irregular pentagon, where n = 5.

Let the supplementary angle with angle 38 be represented by y,

y + 38 = 180

y = 180 - 38

  = 142^{o}

y = 142^{o}

Let the supplementary angle with x be represented by z, so that;

z + 72 + 120 + 100 + 142 = 540^{o}

z + 434 = 540^{o}

z = 540^{o} - 434

  = 106^{o}

z = 106^{o}

But, x + z = 180^{o}

Then;

x + 106^{o} = 180^{o}

x = 180^{o} - 106^{o}

  = 74^{o}

x = 74^{o}

The length of pathway is 10 inches on map.

Step-by-step explanation:

Given,

Total distance = 350 miles

According to map,

1 inch = 35 miles

Let, x be the number of inches on map.

Therefore, using proportion;

Inch : mile :: inch : mile

1:35::x:350\\

Product of mean = Product of extreme

35*x=350*1\\35x=350\\

Dividing both sides by 35;

\frac{35x}{35}=\frac{350}{35}\\x=10

The length of pathway is 10 inches on map.
