Answer:

see explanation

Step-by-step explanation:

Given

a = \left[\begin{array}{ccc}3\\2\\\end{array}\right]

To obtain -3a multiply each of the elements of a by -3

3a = \left[\begin{array}{ccc}-3(3)\\-3(2)\\\end{array}\right] = \left[\begin{array}{ccc}-9\\-6\\\end{array}\right]

To obtain 1.5a multiply each element by 1.5

1.5a = \left[\begin{array}{ccc}1.5(3)\\1.5(2)\\\end{array}\right] = \left[\begin{array}{ccc}4.5\\3\\\end{array}\right]

End of day/Distance from home
charle [14.2K]

Answer:

\large \boxed{\text{B) 374 mi/day}}  

Step-by-step explanation:

The average rate of change from one point to another is the slope of the straight line joining the two points.

\text{slope} = \dfrac{ y_{2} - y_{1}}{ x_{2} - x_{1}}

From Day 1 to Day 3, your points are (1, 383) and (3, 1132).  

\text{Slope} = \dfrac{1132 - 383 }{3 - 1} =  \dfrac{749 }{2} = \textbf{374 mi/day}\\\\\text{The average rate of change from Day 1 to Day 3 was $\large \boxed{\textbf{374 mi/day}}$}

The graph below shows the rate of change from Day 1 to Day 3 as a black line. It appears from the graph that Adam and his dad kept the same rate of change for the whole trip.

14/10 = 7/5
The answer is 7/5.

An ocean front lot has a perimeter of 250 feet and an area of at least 2500 square feet. Write an inequality describing this sit
evablogger [386]

Answer:

So, the inequality is

x(125-x)\geq 2500

Step-by-step explanation:

Since, the shape of ocean front is rectangular

Let's assume length of rectangle is x feet

width of rectangle us y feet

we are given

An ocean front lot has a perimeter of 250 feet

so, we get

2x+2y=250

now, we can solve for y

x+y=125

y=125-x

now, we can find area

Area=xy

now, we can plug back y

Area=x(125-x)

an area of at least 2500 square feet

so, we get

x(125-x)\geq 2500
