Calculate the average rate of change for the graphed sequence from n = 2 to n = 4.
(2 points)

Answer:

r = 3.7 cm

Step-by-step explanation:

19.02 = 1/2π(2radius) + diameter

expanding:

19.02 = 1/2(3.14)(2r) + 2r

19.02 = 3.14r + 2r = 5.14r

r = 19.02/5.14 = 3.7 cm

Answer:

[tex] 10 \: { \: m}^{2} [/tex]

Step-by-step explanation:

area of the shaded region = Area of triangle formed in rectangle with base (10 - 6 = 4) 4m and height 2 m + Area of triangle formed in square with base 2 m and height 6 m

[tex] = \frac{1}{2} \times 4 \times 2 +\frac{1}{2} \times 2\times 6 \\ \\ = 4+6 \\ \\ = 10 \: { \: m}^{2} [/tex]

Answer:

shaded region = 10 m squared

Step-by-step explanation:

Area square = 6x6 = 36    Area reatangle 4x2 = 8

both areas = 44

Now lets subtract some white parts to obtain the shaded parts

1/2 of 4x6 = 12

1/2 of 6x6 = 18

1/2 of 4x2 =4

12+18+4= 34

44-34 = 10

-8y+4

-2y-6y=-8y

7-3=4

-8y+4

Answer:

21 hours

Step-by-step explanation:

Since 2^8 = 256, that means it will take 7 half-lives to become two gallons

7 half-lives * 3 hours = 21 hours

256, 128, 64, 32, 16, 8, 4, 2

Answer:

Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is too toxic for any clean-up efforts. She residents will

Step-by-step explanation:

To solve half-life problems, you use the equations:

f(t) = T0 (1/2)^(t/t1/2). where T0 is the initial mass and T1/2 is the half-life.

So we get f(20)= 5 = T0•(1/2) ^ 20/11

T0 = 17.63 mg

For the second part of the question, we plug 0.5 mg into the equation:

0.5 = 17.63 • (1/2)^ t/11

t = 56.5 days

Answer:

D

Step-by-step explanation:

379.00 - 15.00 + 154.00 x 3 + 65.00 + 13.00 = 904

0.55 x 63 = 34.65

34.65 + 904 = 938.65

Answer:

Your answer is D

Step-by-step explanation:

because 379-15+154x3+65+13+0.55x63=938.65

Answer:

156 ft²

Step-by-step explanation:

the shaded area is a trapezoid

The area of the trapezoid: (6 + 18) × 13 ÷ 2 = 156

Answer: 2.5 is greater than x

Step-by-step explanation:

Answer:

a=-2

We move all terms to the left:

2(2a+3)-6-(5a+2)=0

We multiply parentheses

4a-(5a+2)+6-6=0

We get rid of parentheses

4a-5a-2+6-6=0

We add all the numbers together, and all the variables

-1a-2=0

We move all terms containing a to the left, all other terms to the right

-a=2

a=2/-1

a=-2

Step-by-step explanation:

We move all terms to the left:

2(2a+3)-6-(5a+2)=0

We multiply parentheses

4a-(5a+2)+6-6=0

We get rid of parentheses

4a-5a-2+6-6=0

Answer:

a = -2

Step-by-step explanation:

2(2a+3)-6=5a+2

distrubute the 2

4a + 6 - 6 = 5a + 2

   combine like terms

    4a = 5a + 2

    -5a     -5a

        -a = 2

         a = -2

Answer:

The answer is 6.

Step-by-step explanation:

All you need to do is turn 33 and 44 into a fraction ([tex]\frac{33}{44}[/tex]). Then you need to simplify it and it's simplest form is [tex]\frac{3}{4}[/tex]. then you up the fraction to [tex]\frac{6}{8}[/tex] and that's your answer.

Answer:

Step-by-step explanation:

start the line from the 75 going to the 80. thats where you put the line on the thing. and im not sure with the 2nd one look it up or find someone to help u:)

Well, by the segment addition postulate, 3x + 5 + 5x - 7 = BD, so BD = 8x - 2.

Because you didn't include the instructions in the picture, I can't be sure if this is a rhombus or a rectangle, but if it is either, then 3x + 5 = 5x - 7, and x = 6

If this is true, then BD = 48 - 2 = 46, but only if the shape is either a rhombus or rectangle (or both would make it a square).

Answer:

The correct answer is A. 18 cm2

Answer:

53.8 mi^2

Step-by-step explanation:

First we need to determine the radius of the crater.  The circumfence formula is C = 2(pi)r, and here C = 26 miles.  Thus,

26 mi = 2(pi)r, so that

      26 mi

r = ------------ = 4.13 miles

        2pi

Then the area of the crater  is A = (pi)r^2, or:

A = 3.14(4.13 mi)^2 = 53.8 mi^2
