There are no options, but I would assume that these sequences would be geometric: 16, -8, 4, -2, 1 -15, -18, -21.6, -25.92, -31.104, 625, 125, 25, 5, 1 can possibly be the correct ones.

I’m tired and I need to explain this. But I don’t feel like writing it

alina1380 [7]

Answer:

area of the figure A is 7.5m^2

Step-by-step explanation:

figure A is the combination of rectangle and triangle.

area of figure A = area of triangle + area of rectangle

= 1/2 X b X h + L X b

= 1/2 X 1 X (1+1+1) + (1+1+1) X (1+1)

= 0.5 X 1 X 3 + 3 X 2

= 1.5 + 6

= 7.5 m^2

3.920 * (1.018)^x = 5.500<br><br>X=?

Andrei [34K]

Answer:

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
Then we can divide both sides by ln(1.108) to get: $x=\frac{ln(1.403)}{ln(1.018)}$
Then using a calculator we get x = 18.98 ≈19
