12 - 3 = 9

Your answer is 9

Hope this helps :)

You need to use PEMDAS, which stands for

P - Parenthesis
E - Exponent
M - Multiplication (left to right)
D - Division (left to right)
A - Addition (left to right)
S - Subtraction (left to right)

So solve using this.
8+4-3 \\ 12-3 \\ 9

Mrs johnson grows herbs in square plots Her basil plot measures. 5. 9 yd on each side. A. Find the total area of the basil plot.
UNO [17]

Answer:

Area = 34. 81 yd^2

Perimeter = 86.6 feets

Step-by-step explanation:

Given the following :

Shape of Mrs. Johnson's plot = square

All sides of a square are of equal length

Measure of each side = 5.9 yd

A.) Area of plot

Area of plot = Area of a square

Area of a square(A) = a^2

Where a = side length

A = 5.9^2

A = 34.81 yd^2

B) Perimeter of Basil plot = Perimeter of a square

Converting yard to feet

1 yard = 3feets

Therefore,

5.9 yards = (3 * 5.9) = 17.7 feets

Fence is 2ft from the garden on each side,

Length of fence on each side = (2 + 17.7 + 2) Feets = 21.7 Feets

Perimeter of a square (P) = 4a

Where a = side length

P = 4 × 21.7

P = 86.6 feets

I will give brainliest to anyone who gives me a correct answer
Pachacha [2.7K]

Answer:

C

Step-by-step explanation:

Let's check the first condition [y=110, t=0] for all the choices and eliminate:

A)

y = 110e^{7t} - 80\\y = 110e^{0} - 80\\y=30

NO

B)

y = 110 - 80e^{-5t}\\y = 110 - 80e^{0}\\y=30

NO

C)

y = 30 + 80e^{-2t}\\y = 30 + 80e^{0}\\y=110

YES

D)

y = 110 - 80e^{2t}\\y = 110 - 80e^{0}\\y=30

NO

E)

y = 30 - 80e^{-4t}\\y = 30 - 80e^{0}\\y=-50

NO

Note: e^0 = 1

Only C is satisfied. But let's make sure the 2nd condition applies as well.

y = 30 + 80e^{-2t}\\y = 30 + 80e^{-\infty}\\y=30+\frac{80}{e^{\infty}}\\y>>30

Hence, y approaches 30 as t goes to infinity. 2nd condition is satisfied as well.

Answer is C
