Answer:

<em>MQ = 16 units</em>

Step-by-step explanation:

$\frac{x}{14}$ = $\frac{9}{63}$

x = $\frac{14*9}{63}$ = 2

<em>MQ</em> = 14 + 2 = <em>16 units</em>

Find a and b so that f(x) = x^3 + ax^2 + b will have a critical point at (2,3).

Digiron [165]

Using the critical point concept, it is found that a = -3 and b = 7.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

$f^{\prime}(x) = 0$

In this problem, the function is:

$f(x) = x^3 + ax^2 + b$

Hence, the derivative is:

$f^{\prime}(x) = 3x^2 + 2ax$

Then:

$f^{\prime}(x) = 0$

$3x^2 + 2ax = 0$

$x(3x + 2a) = 0$

$x = 0$

$3x + 2a = 0$

$3x = -2a$

$x = -\frac{2a}{3}$

Since the critical point is at x = 2, we have that:

$-\frac{2a}{3} = 2$

$-2a = 6$

$2a = -6$

$a = -3$

Then:

$f(x) = x^3 - 3x^2 + b$

Critical point at (2,3) means that when $x = 2, y = 3$ , then:

$3 = 2^3 - 3(2)^2 + b$

$8 - 12 + b = 3$

$b = 7$

Answer:

$d = 9$

Step-by-step explanation:

Given

$Morning = -7^{\circ}C$

$Afternoon = 2^{\circ}C$

Required

What represent the difference

The expression that represents the difference (d) are:

$d = |Morning - Afternoon|$

Substitute values for Morning and Afternoon

$d = |-7 - 2|$

$d = |-9|$

$d = 9$
