Answer:

x = \frac{10y + 18}{2}

s = \frac{n}{2}

Step-by-step explanation:

2x - 10y = 18

2x = 10y + 18

x = \frac{10y + 18}{2}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

n = \frac{s+360}{180}

180n = s + 360

s = 180n/360

s = \frac{n}{2}

Answer:

x = 5y + 9

Step-by-step explanation:

2x - 10y = 18

2x = 18 + 10y (add 10y to both sides)

x = 9 + 5y (divide both sides by 2 to isolate the variable)

x = 5y + 9 (just reorder to have the variable first)

The coordinates of point J are (5, −6) and the coordinates of the point K are (7, 8).
Yakvenalex [24]

Answer:

The coordinates of the point one half the distance is (6,1)

Step-by-step explanation:

Here we want to calculate the coordinates one half of the line segment.

This in another way simply means the coordinates of the midpoint of that segment;

Mathematically;

we proceed with this using the midpoint formula

(x,y) = (x1 + x2)/2, (y1 + y2)/2

From the question (x1,y1) = (5,-6) while (x2,y2) = (7,8)

let’s say

(x,y) = (5 + 7)/2 , (-6 + 8)/2

(x,y) = 12/2, 2/2

(x,y) = (6,1)

The number y of hits a new website receives each month can be modeled by y = 4070ekt, where t represents the number of months th
makvit [3.9K]

Answer:

<u><em>k = 0.2645</em></u>

Step-by-step explanation:

Given model:

y = 4070 e^{kt}

y = no. of hits website received = 9000 (in 3rd month)

t= no. of months website has been operational = 3

put in the above equation:

9000 = 4070  e^{3k}

\frac{9000}{4070} = e^{3k}

\frac{900}{407}=e^{3k}

<u><em>Taking natural logarithm on both sides, we get:</em></u>

ln\frac{900}{407}=ln(e^{3k})

ln\frac{900}{407}= 3k ln<em>e</em>

ln<em>e</em>=1

ln \frac{900}{407}= 3k

or k = \frac{1}{3}ln\frac{900}{(407)}

k =\frac{1}{3}(0.7936)

<em>k = 0.2645</em>

<em />
