Answer:

The height of the tree in 2020 was of 19.63 feet.

Step-by-step explanation:

Exponential equation for growth:

The exponential equation for the growth of an amount has the following format:

H(t) = H(0)(1+r)^t

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.

A 4 foot tree was planted in 2012 outside a high school.

This means that H(0) = 4

The tree grew continuously by 22% each year from that point.

This means that r = 0.22

Find out what the height of the tree was in 2020.

2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).

H(t) = H(0)(1+r)^t

H(t) = 4(1+0.22)^t

H(4) = 4(1.22)^t

H(4) = 4(1.22)^8 = 19.63

The height of the tree in 2020 was of 19.63 feet.

Y−3=2(x+1) solve this
Elena-2011 [213]

Answer:

Y-3 = 2(x+1)

open the brackets

Y-3 = 2x+2

Y = 2x+5..... this is the answer when solving for Y

if were solving for x:

Y-3 = 2x+5

Y-8 = 2x

\frac{y}{2} -4 = x

Classify the triangle with side lengths 11 cm, 30 cm, and 39 cm as acute, right, or obtuse​
Ahat [919]

Answer:

This triangle is a obtuse traingle.

Step-by-step explanation:

First of all, it is impossible that this triangle is actute since the sides are different length.

Right is also not possible ( in this case ) because there are two pretty far sides.

30, 39

A obtuse triangle have a short side of 11 cm pointing top right and a side of 30 cm pointing directly to the right and the 39 cm side connecting the ends of the other sides.

                                        \                   Third side ( 39 cm , the one connecting

First side ( 11 cm )              \                   the ends of side 1 and 2)

                                            \______________

                                               Second side ( 30 cm )

PLEASE HELPPPPPPPPPP
Sauron [17]

Answer:

167/346 or 0.483

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of Tails (T) = 167

Number of Heads (H) = 179

Probability of tail, P(T) =?

Next, we shall determine total outcome. This can be obtained as follow:

Number of Tails (T) = 167

Number of Heads (H) = 179

Total outcome (S) =?

S = T + H

S = 167 + 179

Total outcome (S) = 346

Finally, we shall determine the probability of tails. This can be obtained as follow:

Number of Tails (T) = 167

Total outcome (S) = 346

Probability of tail, P(T) =?

P(T) = T / S

P(T) = 167 / 346

P(T) = 0.483

Thus, the probability of tails is 167/346 or 0.483
