jeyben [28]

Answer:

The perimeter of the garden is 126.81 feet.                                      

Step-by-step explanation:

We are given the following in the question:

Dimensions of rectangle:

Length, l = 33 feet

Width, w = 21 feet

Dimension of semicircle:

Diameter of circle, d = 33 feet

r = \dfrac{d}{2} = \dfrac{33}{2} = 16.5

Perimeter of garden =

P =\text{(Length + 2(Width)) + Perimeter of semi circle}\\P =l + 2(w) + \pi(r)\\P = 33 + 2(21) + 3.14(16.5)\\P = 126.81

Thus, the perimeter of the garden is 126.81 feet.

Solve the equation to find where the treste ground levelEnter your answers from least to greatest and round to the nearest The m
DaniilM [7]

Answer:

The trestle meets ground level at 0.875 units and 9.125 units

Step-by-step explanation:

Poorly formatted question.

The given equation is:

y = -x^2 + 10x - 8

Required

The point where the trestle gets to the ground level

To do this, we set y = 0

So, we have:

-x^2 + 10x - 8 = 0

Multiply through by -1

x^2 -10x + 8 = 0

Solve using quadratic formula:

x= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}

Where:

a = 1; b =-10; c = 8

So, we have:

x= \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*8}}{2*1}

x= \frac{-(-10) \± \sqrt{68}}{2*1}

x= \frac{-(-10) \± 8.25}{2}

x= \frac{10 \± 8.25}{2}

Solve the fraction

x= 5 \± 4.125

Split

x= 5 + 4.125\ or\ x= 5 - 4.125

x= 9.125\ or\ x= 0.875
