Inequality, because want to know when we'll make a profit.
d (- 680+ 960) \geqslant 52000 \\  280d \geqslant 52000
Profit: Let's See When 280d equals 52000

d \geqslant  \frac{52000}{280}  \\ d \geqslant 185.71
So, after 190 days Julianne will make a profit
280(190) \geqslant 52000 \\ 53200

The equation d=4 -1/15t represents your distance from home,d, for each minute you walk,t. If you graphed this equation, determin
Readme [11.4K]

we have

d=4 -\frac{1}{15}t

using a graph tool

see the attached figure

For t=0 d=4 -------> the y-intercept

that means that at the time t=0 the house was four units away.

For t=60 min  d=0 -------> x-intercept

that means he was already at home at the time t=60 minutes.

therefore

the graph of this equation represents the walk towards the house

Hoochie [10]

Answer:

B. 5√3 is your answer.

Step-by-step explanation:

This is an equilateral triangle, which means that all external sides (that make up the triangle) have the same measurement.

This means that line segment AC = 10.

Solve for the measurement of line segment AB. Line Segment AB is 1/2 of AC, making it: 10/2 = 5

Line AB = 5

Line AD = 10

This is a 1, √3, 2 triangle, in which:

1 = 5

2 = 10

Solve for √3. Multiply √3 with the 1:

5 x √3 = 5√3

B. 5√3 is your answer.
