4a + 3 - 9 = -7 + 2 + a
4a - 6 = -5 + a
4a - a = -5 + 6
3a = 1 / : 3
a = 1/3

$4a + 3 - 9 = -7 + 2 + a\\
4a-6=-5+a\\
4a-a=-5+6\\
3a=1\ /:3\\
a=\frac13$

Paul drove 225 miles to visit his parents. The graph below shows the distance traveled and the total time of the trip. Write and

ziro4ka [17]

50mph

Step-by-step explanation:

The image of the motion of Paul's derive is attached already.

From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.

What is average speed?

Average speed is the rate of change of total distance covered with time taken .

Average speed = $\frac{total distance }{time}$

To find the total distance covered;

Distance at time 1 = 75miles

Distance at time 4 = 225miles

Distance covered between 1 - 4 = 225 - 75 = 150miles

Time taken for the journey = 4 - 1 = 3hrs

Input the values in the equation;

Average speed = $\frac{150}{3}$ = 50mph

The main sail of a sailboat has the dimensions shown in the figure at the right. What is the height of the main sail?

levacccp [35]

Answer:

$h = 16.1$

Step-by-step explanation:

$sin A /a = sin B / b = sin C/c$ where A is angle and a is side opposite of angle

$sin (49) / h = sin(41)/ 14$ cross-multiply

$h*sin(41) = 14 * sin(49)$

$h = (14*sin(49))/ sin(41)$

$h = 16.1$

Hello from MrBillDoesMath!

Answer:

a(n) = -3n , n>= 1

Discussion:

a(1) = -3

a(2) = -6

a(3) = -9

a(4) = -12

The pattern looks like a(n) = -3n

Thank you,
