Answer:

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by the formula ...

an = a1 + d(n -1)

where a1 is the first term (5.5) and d is the common difference (0.5).

So, the n-th term is ...

an = 5.5 +0.5(n -1) = 5.0 +0.5n

For n = 100, the term is ...

a100 = 5.0 +0.5(100) = 55

The 100th term of the sequence is 55.

Answer:

55.

Step-by-step explanation:

The explicit formula for the nth term is a1 + d(n - 1).

Here d = 6 - 5.5 = 0.5 and a1 = 5.5.

So the 100th term = 5.5 + 0.5(100-1)

= 55.

Write in slope intercept form an equation of the line that passes through the points (-5,6) and (3,10)

lisov135 [29]

Answer:

y= 1/2x + 17/2

Step-by-step explanation:

First, find your slope using y-y1/x-x1. This is your expression: 10-6/3--5. 10-6 equals 4, and 3--5 equals 8. Your slope is 4/8, but it can be simplified to 1/2. This should be your current equation: y=1/2x+b. Plug in one of your ordered pairs to the equation, it doesn't matter which pair you want to use. I'm using the second ordered pair, so this is what you would have: 10=1/2(3)+b. Multiply 1/2 by 3 to get 3/2. This is what it should look like: 10=3/2+b. Subtract 3/2 from both sides to get your y-intercept of 17/2. Go back to your original equation and plug in your y-intercept. This is your final answer: y= 1/2x + 17/2. Hope this helped!

A monument has a base and a statue. The base is a rectangular prism that measures 4 ft by 6ft by 2 ft. The statue is a cube with

valina [46]

So find the volume of the separate shapes. For rectangular prisms (which includes cubes), multiply width by height by length. So multiply 4 by 6 by 2. And for the cube, multiply 2 by 2 by 2. Then, to find the total volume, add the two together.
