Answer:

Step-by-step explanation:

The coefficients of the expansion of (a + b)^2 are 1 2 1, which is the third row of Pascal's triangle.

For (a + b)^3 they are 1 3 3 1 which is in the 4th row, and so on

So those for the (a + b)^n are in the (n + 1)th row.

C the coefficients in the expansion (a+b) are given by the (n+1) row of Pascia’s triangle.

Hey!

Explanation:

↓↓↓↓↓↓↓↓↓↓

First, remove parenthesis.

$7i4i$

Secondly, multiple by the numbers.

$7*4=28$

$-28ii$

Third, apply exponents rule.

$-28i^2$

$i^2=-1$

$-28(-1)$

Finally, refine.

$=28\\$

How many solutions does this equation have?

Greeley [361]

Answer:

No solution

Explanation:

-4+19-7f = -15-7

cancel terms on both sides ( add 7f on both sides)

Calculate the sum

-4+19= -15

-4+19=15

15 = -15

The statement 15 = -15 is false so there is no solution :)

Find the surface area of the triangular prism

melomori [17]

Answer:

608 ft²

Step-by-step explanation:

1) Find the area of the bases

$A=\frac{1}{2} bh$ where b is the base length and h is the height

Plug in b and h

$A=\frac{1}{2} (12)(8)\\A=48$

Multiply the answer by 2 (because there are 2 bases)

A=96

Therefore, the area of the two bases is 96 ft².

2) Find the area of the two sides facing up

$A=lw$ where l is the length and w is the width

Plug in l and w

$A=10*16\\A=160$

Multiply the answer by 2 (because there are 2 sides)

A=320

Therefore, the area of these two sides is 320 ft².

3) Find the area of the bottom side

$A=lw$ where l is the length and w is the width

Plug in l and w

$A=12*16\\A=192$

Therefore, the area of this side is 192 ft².

4) Add all the areas together

96 ft² + 320 ft² + 192 ft²

= 608 ft²

Therefore, the surface area of the triangular prism is 608 ft².

I hope this helps!

You are driving on a highway and are about 55 miles from a state border. You set your cruise control at 60 miles per hour and pl

kumpel [21]

Based on your distance from the state border and the cruise control speed, the minimum and maximum hours you will have cruise control on is:

Minimum - 1/3 hours
Maximum - 1.5 hours

<h3>How long will cruise control be on?</h3>

You are 55 miles from the state border. You want to put the cruise control off within 35 miles of the border on either side.

This means that you might put it off in:

= 55 - 35

= 20 miles

The time to 20 miles is the minimum time the cruise control will be on:

= 20 miles / 60 miles per hour

= 1/3 hours

If you put it off 35 miles after the border, the distance is:

= 55 + 35

= 90 miles

The maximum time is:

= 90 / 60

= 1.5 hours
