Two points defining a linear function are shown in the table below. x y –14 –18 –10 –12 What is the slope of the function? Two-t

Mazyrski [523]

Answer:

Option B.

Step-by-step explanation:

From the given table it is clear that the linear function passing through the points (-14,-18) and (-10,-12).

The slope of a linear function is

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

The given line passing through the points (-14,-18) and (-10,-12), so the slope of the line is

$m=\dfrac{-12-(-18)}{-10-(-14)}$

$m=\dfrac{-12+18}{-10+14}$

$m=\dfrac{6}{4}$

$m=\dfrac{3}{2}$

The slope of the required line is $\dfrac{3}{2}$ .

Therefore, the correct option is B.

Suppose two telephone poles are 60 ft apart and the length of the wire between the poles is 61 ft. If the lowest point of the wi

Brut [27]

Answer:

H=22.5ft

Step-by-step explanation:

According to the graph, we must find y to determine the height at which the rope must be placed so that the lowest point of the rope is 17 ft high .

applying the pythagorean theorem

$h^{2}=x^{2} +y^{2}\\y^{2}=h^{2} -x^{2}\\y^{2}=30.5^{2} -30^{2}\\ y^{2}=930.25-900\\y=\sqrt{30.25}=5.5ft$

then H=17ft+5.5ft=22.5ft

What order will result in a final output of - 31 when the initial input is 0?? Someone please please helpoo

morpeh [17]

The order that will result in a final output of -31 when the first input is 0 is as follows; Third → Second → Fourth → First

<h3>How to find the order?</h3>

First gives;

y = -2·x + 34 = 18

Second gives;

y = -x/3 - 10 = -38/3

Third gives;

= -24

Fourth gives;

y = (x - 2)² = 36

We have after several iterations;

Third gives,

= -24

Next we input into the second to get,

y = -(-24)/3 - 10 = 24/3 - 10 = 8 - 10 = -2

Next we input into the fourth to get,

y = ((-2) - 2)² = (-4)² = 16

Next we input into the first to get,

y = -2×16 + 34 = -32 + 34 = 2

Which gives the order as follows;

Third → Second → Fourth → First

b) $264

Step-by-step explanation:

The full question is: a. What did Peter do incorrectly? b. What is the correct amount of interest?

Using the equation $I=prt$ , we can substitute the given values.
I = 275 x 0.08 x 12
I = 264
