What is the value of p in the question below. 10x9/2x4= px 5

Mathematics
1 answer:
ycow [4]2 years ago
7 0

Answer:

p = 5

Step-by-step explanation:

We have that:

\frac{x^{a}}{x^{b}} = x^{a-b}

So

\frac{x^{9}}{x^{4}} = x^{9-4} = x^{5}

10/2 = 5

Then

\frac{10x^{9}}{2x^{4}} = 5x^{9-4} = 5x^{5}

Finding p:

5x^{5} = px^{5}

p = \frac{5x^{5}}{x^{5}}

p = 5

F(x) = — 3х2 – 6х +5 <br> maximum and minimum value
gregori [183]

9514 1404 393

Answer:

  maximum: 8; no minimum

Step-by-step explanation:

A graph can be useful. I find a graphing calculator handy. It shows the maximum of the function is f(-1) = 8. Since the parabola goes to -∞ for large values of x, there is no minimum.

  maximum: 8

__

You can also find the maximum by putting the function in vertex form.

  -3(x^2 +2x) +5 . . . . factor the leading coefficient from the x terms

 -3(x^2 +2x +1) +5 -(-3)(1) . . . . add the square of half the x-coefficient, subtract the equivalent amount

  -3(x +1)^2 +8 . . . . . . the vertex form of the expression for f(x)

This form is ...

  a(x -h)^2 +k . . . . . with a=-3, h=-1, k=8

so the vertex is (h, k) = (-1, 8) -- the same as shown on the graph. The negative value of 'a' tells you the parabola opens downward, so the vertex is the maximum. The maximum is 8 at x = -1.

Simplify (3 + 2i)(7 − 5i).
erma4kov [3.2K]
Rule needed: i^2 = -1
Standard form a + bi

(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
