Cosα=x/L

L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:

L=48/cos39 ft

L≈61.76 ft (to nearest hundredth of a foot)

Find the coordinates of the vertex of the following parabola algebraically. Write your answer as and x,y point
Likurg_2 [28]

The equation of the parabola in the vertex form is y =  (x - 3)^{2} - 5 with ( 3, -5) is the vertex of the parabola and 1 is the multiplier

In the above question, A parabolic equation is given as follows:

Y = x^2 - 6x + 4

The equation of the parabola in the vertex form is :

y = a (x - h)^{2} + k

Where a is a multiplier in the equation and (h,k) are the coordinates of the vertex

So, in order to obtain this form, we will use the method of completing square :

Y = x^2 - 6x + 4

y = x^{2} - 6x + (9 -9) + 4

y = (x - 3)^{2} + ( -9 + 4)

y =  (x - 3)^{2} - 5

where, ( 3, -5) is the vertex of the parabola and 1 is the multiplier

Hence, The equation of the parabola in the vertex form is y =  (x - 3)^{2} - 5 with ( 3, -5) is the vertex of the parabola and 1 is the multiplier

Round your answer to the nearest hundreth​
Juliette [100K]

Answer:

<em>201.06 sq. ft.</em>

Step-by-step explanation:

Area of a circle is found by using the equation:

A = \pi r^{2}

Radius = 1/2 (diameter) = 1/2 (16) = 8

So plug in:

A = \pi (8)^{2}

A = 64\pi

A = 201.06193

Rounded A= 201. 06

1) 2x + 8y = 20 what's the solution so confused <br> y = 2
postnew [5]
If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20 
2x + 16 = 20 
2x = 20 - 16
2x = 4 
x = 4/2 
x=2 :)))
i hope this is helpful
