Answer:

Step-by-step explanation:

-a b-3ab-C+ 3ab2 - 2a² b + ab

where a = -1, b = -3 and c = = 10:

= -(-1)(-3)-3(-1)(-3)-10+3(-1)(-3)2-2(-1)²(-3)+(-1)(-3)

= -(3)-(3)-10+6(3)-2(3)+3

=-3-3-10+18-6+3

=-22+21

= -1

Readme [11.4K]

Answer:

677

Step-by-step explanation:

the sequence is 1, 2, 5, 26, 677

the first term is 1

to find the 2nd term, do: $1^{2} +1=2$

3rd: $2^{2} +1=4+1=5$

4th: $5^{2} +1 =25 +1=26$

5th: $26^{2} +1=676+1=677$

Write an expression to represent each of the following sketches. Then give the value of each sketch.

zysi [14]

The sketches are illustrations of inequalities

The first sketch is: $-2 \le x \le 5$ .
The second sketch is: $3 \ge x \ge -4$

Sketch A

In sketch A, we have the following observations:

The arrow faces left (this implies less than)
The dots on -2 and -5 are closed dots (this implies less than or equal to).

Hence, the inequality is:

$-2 \le x \le 5$

Sketch B

In sketch B, we have the following observations:

The arrow faces right (this implies greater than)
The dots on -4 and 3 are closed dots (this implies greater than or equal to).

Hence, the inequality is:

$3 \ge x \ge -4$

You want the total volume of a cuboid 1" × 10" × 38" and a cylinder 1" in diameter by 12" long.

Volume of a cuboid:
.. V = l*w*h
.. = (38")*(10")*(1")
.. = 380 in³

Volume of a cylinder:
.. V = (π/4)*d²*h
.. = (3.14/4)*(1")²*(12")
.. = 9.42 in³

Total volume = Volume of cuboid + Volume of cylinder
.. = 380 in³ +9.42 in³
.. = 389.42 in³

The volume of the coat rack is approximately 389.42 in³.

Neil has 3 partially full cans of white paint. They contain 1/3 gallon. 1/5 gallon and 1/2 gallon of paint about how many paint

mariarad [96]

Answer:

About 1 gal

Step-by-step explanation:

When you are estimating with fractions, you should round them off to the closest integers that you can work with in your head.

⅓, ⅕, and ½ are all close to zero, but that's absurd, because Neil clearly has some paint .

Instead, let's estimate that ⅓ gal + ⅕ gal make about ½ gal.

They still have the other ½ gal, and

½ gal + ½ gal = 1 gal.

Neil has about 1 gal of paint.
