Answer:

3rd Option is correct.

Step-by-step explanation:

Given:

Angle of elevation from L to K = 39°

J is the vertex of the Right angled triangle.

To find: JL

Figure is attached.

In ΔJKL,

Using Trigonometric ratio,

$cos\:39=\frac{JL}{KL}$

$0.77=\frac{JL}{12}$

JL = 0.77 × 12

JL = 9.324

JL = 9.3

Therefore, 3rd Option is correct.

Based upon historical data, it is known that 8% of 12-egg cartons contain at least one broken egg. A grocery store manager would

kakasveta [241]

Based on the 5 trials, 1 carton of eggs is expected to contain at least one broken egg, on average

<h3>How to determine the number of cartons</h3>

From the question, we understand that only one of the first 10 double-digit numbers is between 01 and 08

This means that:

The average carton or the expected value of eggs in the simulation is 1

Hence, 1 carton of eggs is expected to contain at least one broken egg, on average

Find a formula for the given polynomial.

levacccp [35]

In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

$p(x) = -0.5(x^3 - x^2 + 6x)$

------------------------

Equation of a polynomial, according to it's zeros:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

------------------------

Identifying the zeros:

Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

$x_1 = -2, x_2 = 0, x_3 = 3$

Thus

$p(x) = a(x - x_{1})(x - x_{2})(x-x_3)$

$p(x) = a(x - (-2))(x - 0)(x-3)$

$p(x) = ax(x+2)(x-3)$

$p(x) = ax(x^2 - x + 6)$

$p(x) = a(x^3 - x^2 + 6x)$

------------------------

Leading coefficient:

Passes through point (2,-8), that is, when $x = 2, y = -8$ , which is used to find a. So

$p(x) = a(x^3 - x^2 + 6x)$

$-8 = a(2^3 - 2^2 + 6*2)$

$16a = -8$

$a = -\frac{8}{16} = -0.5$

------------------------

Considering the zeros and the leading coefficient, the formula is:

$p(x) = -0.5(x^3 - x^2 + 6x)$
