The smith family is designing new plans for an in ground pool. mr smith draws a rectangular shape with a length that is 5 feet l

dolphi86 [110]

Answer
Are of the pool = w² + 5w (in square feet)

Explanation

Since the pool is rectangular in shape,
Area of the pool can be calculated using the formula for the area of a rectangle

Area of rectangle = length x width

Given,
Width of pool (Assume is same as height) = w
Length of pool= w + 5

Area = w * (w + 5)
= w² + 5w (in square feet)
where w is the width of the pool

The yield of strawberry plants depends on the amount of fertilizer fed to the plants. Agricultural research shows that an acre o

andre [41]

Answer:

657 pounds

Step-by-step explanation:

Given

Represent the amount of fertilizer with x and the yield with y.

So, we have:

$(x_1,y_1) = (70,630)$

$(x_2,y_2) = (100,900)$

Required:

Determine the yield (y) when fertilizer (x) is 73ft^3

Using linear interpolation, we have:

$y = y_1 + (x - x_1)\frac{(y_2 - y_1)}{(x_2 - x_1)}$

Substitute the x and y values using

$(x_1,y_1) = (70,630)$ and $(x_2,y_2) = (100,900)$ ;

We have:

$y = y_1 + (x - x_1)\frac{(y_2 - y_1)}{(x_2 - x_1)}$

$y = 630 + (x - 70)\frac{(900 - 630)}{(100 - 70)}$

$y = 630 + (x - 70)\frac{270}{30}$

$y = 630 + (x - 70)*9$

Open bracket

$y = 630 + 9x - 630$

$y = 9x - 630+630$

$y = 9x$

To solve for y when x = 73.

We simply substitute 73 for x

$y = 9x$

$y = 9 * 73$

$y = 657$

Hence, the yield for 73 cubic feet is 657 pounds

Find x A)-2 B)5 C)-5 D)9

Arte-miy333 [17]

Answer:

Step-by-step explanation:

From the figure, we can say:

∠NFG + ∠EFN = ∠EFG

We substitute the given measure and write:

6x + 4 + 24 = 12x - 2

Now, we simply solve this algebraically for "x". Shown below:

$6x + 4 + 24 = 12x - 2\\6x+28=12x-2\\28+2=12x-6x\\30=6x\\x=\frac{30}{6}\\x=5$

x is 5, so B is the correct answer.
