18, 26, 34, 42, find the 52nd term and the explicit formula

1 answer:

3 0

We have 26 - 18 = 8; 34 - 26 = 8; 42 - 34 = 8; (an arithmetic progression)
We use the formula an = a1 + (n-1)x8 (the explicit formula)
So, an = 18 + (n-1)x8 ;
Then, an = 8n + 10;
Finally, a52 = 8x52 + 10 = 426 (the 52nd term);

How many cubic centimeters is 5 cubic meters.

tresset_1 [31]

The key to solving this question is first knowing how many cubic cm are in one cubic m:

The ratio is always 1000000 cubic cm in 1 cubic meter.

Knowing this, we calculate how many cubic cm are in 5 cubic meters!

1000000 cubic cm = 1 cubic m
x cubic cm 5 cubic m

x = 1000000 cubic cm x 5 cubic m ÷ 1 cubic m
x = 5000000 cubic cm

Hope this helps!

Simplify this number 300mm:9m

DIA [1.3K]

Answer:

1 : 30

Step-by-step explanation:

300mm:9m

We need to change the meters to mm

1 meter is 1000 mm

so 9 m is 9000 mm

300mm:9000mm

Divide both sides by 300

300mm/300 : 9000/300

1 : 30

What is the slope of the line that passes through these two points? (-3, 2) (4, 2)

Alik [6]

Answer: 0

Step-by-step explanation:

To find slope, I found that an easy way is the equation y2 - y1 over (divided by) x2 - x1

so for this, it would be:

$\frac{2 - 2}{4-(-3)}$

which is 0/7

0 divided by 7 is 0, so there is your answer

Find the area of the blue sector(s). The diameter of the wheel is 12

Ber [7]

We know that to find the area of the entire circle, we are going to use the equation:

$A=\pi r^{2}$

And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.

Now we can use this radius in the equation:

$A=\pi (6)^{2}$

$A=36\pi$

Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide $36 \pi$ by 5 to find the area of each section:

$\frac{36 \pi}{5} =7.2 \pi$

Each section has an area of $7.2\pi units^{2}$ or, using 3.14 for pi, $7.2*3.14=22.61units^{2}$ .

Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:

$22.61*2=45.22units^{2}$

Therefore, the answer is C) 45.2 $units^{2}$ .
