It's a geometric sequence with a first term of 16 and a common ratio of 10, it's rule or function is:

f(n)=16(10^(n-1)) or if you prefer...

f(n)=1.6(10^n)

The pattern is, you just add a zero to each!

Use the commutative property for addition to rearrange the algebraic expression 5x-7y-8x+y

BartSMP [9]

You want to use the addition property, so you need to ADD each term. Just change the minuses to pluses, making sure you keep the negative with the number

5x-8x-7y+y =

5x + -8x + -7y +y

Write a linear equation that contains the points shown in the table.

Afina-wow [57]

Answer:

y=7x+1

Step-by-step explanation:

From the table, the difference in y is 7 and the difference in x is 1.

Let the linear equation be

$y = mx + b$

Where m is the constant difference in y divided by the constant difference in x.

This means m=7/1=7

Our equation now becomes:

y=7x+b

To find b, we substitute any ordered pair from the table.

From the to table, when x=1, y=8.

This implies that,

8=7(1)+b

b=8-7=1

Therefore the equation is y=7x+1

Fabio is driving west away from Albany and towards buffalo along interstate 90 at a constant rate of speed of 62 miles per hour.

emmasim [6.3K]

Answer:

The distance between Albany and Buffalo along the I90 is 288.8 mi.

The speed of Fabio is 62 mph.

After 1.5 hours, he is 221 miles from Albany.

Things we can calculate here:

Using the relation:

Distance = time*speed.

We can calculate the number of miles that he moved in that 1.5 hours.

D = 62mph*1.5h = 93mi.

If after 1.5 hours, he was 221 miles Albany, then before that he was 93 miles closer to Albany.

His initial position was:

221 - 93 = 128 miles away from Albany.

Now we also can calculate the time left to arrive at Buffalo.

We know that the distance between Albany and Buffalo is 288.8 mi

And he is 221 mi away from Albany.

Then the distance left to Buffalo is:

288.8mi - 221mi = 67.8mi

And the time left will be:

Distance/speed = time

67.8mi/62mph = 1.1 hours.

He needs to drive for another 1.1 hours to get to Buffalo.

How do I find the area of the shaded region? Thanks!!

bazaltina [42]

Answer:

The radius of a circumcircle of an equilateral triangle is equal to (a / √3), where ‘a’ is the length of the side of equilateral triangle.

Circle Radius = 16 / sq root (3)

Circle Radius = 9.237604307

Circle Area = PI * radius ^ 2

Circle Area = PI * 85.3333333333

Circle Area = 268.083

Equilateral Triangle area = side^2 * sq root (3) / 4

Equilateral Triangle area = 16^2 * 0.4330127019

Equilateral Triangle area = 110.85

Shaded region = 268.083 - 110.85

Shaded region = 157.233
