Ierofanga [76]2 years ago

Step-by-step explanation:

a geometric sequence means that every term is created by multiplying the previous term by a certain constant factor. this factor is called the "common ratio".

so,

6×r = 18

r = 18/6 = 3

and a quick check tells us this works also for the next terms (18×3 = 54, 54×3 = 162), so it is indeed a geometric sequence with common ratio 3.

a0 = 6

a1 = a0 × 3 = 6×3 = 18

a2 = a1 × 3 = a0 × 3×3 = 6×3² = 54

an = a0 × 3^n = 6 × 3^n

so,

f(x) = 6×3^x, x is integer, x >=0

What is 38.3 minus -1.2?
fenix001 [56]
(38.3 - -1.2) = 39.5

Anytime you have two minuses beside each other, you add. 
If you have a plus sign in the middle, but one of the numbers is negative you subtract. 

Hope that makes sense ! (:

Daniella construct a scale model of a building with a rectangular base remodel is 2 in in length and 1 in in with the scale on t
mash [69]

<u><em>Answer:</em></u>

The actual area of the base of the building is 4418 ft²

<u><em>Explanation:</em></u>

<u>1- Getting the actual dimensions of the building:</u>

We are given that the model used is:

1 in corresponding to 47 ft

<u>Now, we get the actual dimensions:</u>

a. The width of the model base is 1 in which means 47 ft

b. The length of the model base is 2 in which means 2*47 = 94 in

<u>2- Getting the area of the base of the building:</u>

Area of the rectangle is the product of its length and width

<u>We have calculated from part 1:</u>

length of base of building is 94 in

width of base of building is 47 in

<u>This means that:</u>

Area of base of building = 47 * 94 = 4418 ft²

Hope this helps :)

PLEASE ANSWER. I will mark as brainliest for fist correct answer.
Sergeeva-Olga [200]

Step-by-step explanation:

If the total worth of the roll is 50 cents, we know that there are 50 pennies in the roll, and therefore the roll has a height of 50 * 1.52 = 76 mm. The radius of a penny is half its diameter, or 19.05 / 2 = 9.525.

We can find its volume with the formula (πr²) * h, where r and h are the radius and height respectively, and we can approximate 3.14 for π. Plugging these in, we have (3.14 * (9.525)²) * 76 ≈ 2160.8 mm³. Hope this helps!
