Replace x with (x/3).

Note: (x/3) = (1/3x).

f(x/3) = (x/3)^3 + 5

Using a graphing calculator, we can easily see that CHOICE 4 is the right graph.

Answer:

$y = -\dfrac{5}{6} x -\dfrac{31}{3}$

In order to find equation:

<u>Find slope</u>:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{rise}{run}$

$\rightarrow \sf slope: \dfrac{-17-(-7)}{8-(-4)}$

$\rightarrow \sf slope: -\dfrac{5}{6}$

Then find equation using:

y - y1 = m(x -x1) where (x1, y1) are points, m is slope

$\sf \rightarrow y - (-17) = -\dfrac{5}{6} (x - 8)$

$\sf \rightarrow y = -\dfrac{5}{6} x + \dfrac{20}{3} -17$

$\sf \rightarrow y = -\dfrac{5}{6} x -\dfrac{31}{3}$

Last year, 31 2 acres of strawberry fields produced approximately 14,700 pounds of strawberries. This year the number of acres p

USPshnik [31]

So in 5 acres of land produces 21,000 pounds of strawberries.

Step-by-step explanation:

Step 1:

Last year, $3\frac{1}{2}$ acres i.e 3.5 acres produced 14,700 pounds of strawberries. So we need to determine how many strawberries were produced per acre.

To do this we divide the total number of strawberries produced by the number of acres it was produced in.

The number of strawberries produced per acre $= \frac{14,700}{3.5} = 4,200$ pounds.

Step 2:

To determine the number of strawberries in 5 acres of land, we multiply the number of strawberries per acre by the number of acres.

The number of strawberries produced in 5 acres $= 5(4,200) = 21,000$ pounds.

So in 5 acres of land produces 21,000 pounds of strawberries.

Answer:

is the name of your account from little mermaid? :DDD

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

now just refer to the above ( also copy and paste the above on your computer some where so you have it always)

sin( D )= 28 / 53

sin( E ) = 45 / 53

cos(D) = 45 / 53

cos(E) = 28 / 53
