<h3>Answer: Cam is 11.6 meters below the surface of the water</h3>

=======================================================

Explanation:

Check out the diagram below.

Draw a vertical number line with 0 at the center. The positive values are above it, while the negative values are below it.

Between -15 and -16, closer to -16, plot the value -15.8 to indicate Ben's position. I have done so as the point B.

We move 4.2 units up to arrive at Cam's position

-15.8 + 4.2 = -11.6

So Cam is 11.6 meters below the surface of the water.

Romashka-Z-Leto [24]

Given:

Line P Q has points (-5, 3) and (5, 1).

Line R S has points (-4, -2) and (0, -4).

To find:

The relationship between lines PQ and RS.

Solution:

If a line passing through two points, then the slope of line is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Line P Q has points (-5, 3) and (5, 1). So, slope of line PQ is

$m_1=\dfrac{1-3}{5-(-5)}$

$m_1=\dfrac{-2}{5+5}$

$m_1=\dfrac{-2}{10}$

$m_1=\dfrac{-1}{5}$

Line R S has points (-4, -2) and (0, -4). So, slope of line RS is

$m_2=\dfrac{-4-(-2)}{0-(-4)}$

$m_2=\dfrac{-4+2}{0+4}$

$m_2=\dfrac{-2}{4}$

$m_2=\dfrac{-1}{2}$

Slopes of two parallel lines are equal.

$m_1\neq m_2$

They are not parallel because their slopes are not equal.

Therefore, the correct option is C.

sleet_krkn [62]

Answer:

213 euros per month

Step-by-step explanation:

1dollar = 0.7306euros

thus $3,500 dollars can be found by a rule of three

dollar euro

1 ⇒ 0.7306

3500 ⇒ x

we find x as follows:

$x=\frac{0.7306*3500}{1} = 2,557.1$ euros

She will pay 2,557.1 euros per year.

Dividing between the 12 months of the year:

$\frac{2,557.1}{12}=213.1$

Rounding to the nearest whole euro she will pay 213 euros per month.

Let C(x) represent the cost of producing x items and p(x) be the sale price per item if x items are sold. The profit P(x) of sel

Nadusha1986 [10]

Answer:

(a) Profit function P(x) = 0.02x^2+60x-80

(b) Average profit P(x)/x = P/x = 0.02x+60-80/x

Marginal profit dP/dx = 0.04x+60

Step-by-step explanation:

Cost function: C(x) = -0.02x^2+40x+80

Price function: p(x) = 100

(a) The profit function P(x) = x*p(x)-C(x) can be expressed as:

$P=x*p-C\\P=x*100-(-0.02x^{2} +40x+80)\\P=0.02x^{2}+60x-80$

(b)Average profit function: P(x)/x

$P/x=(0.02x^{2}+60x-80)/x\\P/x = 0.02x+60-80/x$

Marginal profit function: dP/dx

$P=0.02x^{2}+60x-80\\dP/dx=0.02*2*x+60+0\\dP/dx=0.04x+60$

Ann [662]

First thing to do is to remember, that the circumference of the full circle is 2(6)pi--12pi. you only want about 120 of it so (120/360)=1/3, so you add it into the thing earlier to get, 12pi(1/3)=4pi =12.566... which you can round into 12.6. This is answer choice A.
