Answer:

In the figure below :

d = 2.08, e = 5, c = 5.42 , a = 22.78°, b = 67.22°

Step-by-step explanation:

Side lengths :

2\cdot e=10\\ \Rightarrow e=5 feet\\\frac{d}{e}=\frac{5}{12}\\\Rightarrow d=\frac{25}{12}\approx 2.08 feet

By pythagoras theorem,

c^2=d^2+e^2\\c^2=29.33\\c\approx 5.42 feet

Now to find angles,

a+b+90^{\circ}=180^{\circ}\\\Rightarrow a+b=90^{\circ}\\\tan a=\frac{d}{e}\\\Rightarrow \tan a =0.42\\\Rightarrow a=22.78^{\circ}\\\Rightarrow b=67.22^{\circ}

K^2+5k-6=0 quadratic formula
s2008m [1.1K]
I hope this helps you



1.k^2+5k-6=0


a=1


b=5


c= -6


disctirminant =b^2-4ac


disctirminant =5^2-4.1. (-6)


disctirminant =49


x1= -(5)+ square root of 49/2.1



x1=-5+7/2


x1=1



x2= -5- square root of 49/2.1


x2= -5-7/2


x2= -6

Need help ASAP !!! And show work please
sammy [17]

Answer:

\sqrt{40} or 6.32

Step-by-step explanation:

We can find the distance between two points by using this formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

where the x and y values are derived from the given points

The points given are ( -2 , 5 ) and ( 4 , 3 )

So we plug in the x and y values of those coordinates into the distance formula

\sqrt{(4-(-2)^2+(3-5)^2} \\4-(-2)=6\\3-5=-2\\d=\sqrt{6^2+-2^2} \\6^2=36\\-2^2=4\\36+4=40\\d=\sqrt{40}

or 6.32

I need help, pls can somebody help on this, it due this Friday

Answer:

To express percentages in decimal form, you start with the decimal on the right side of the percentage, then you bring the decimal two places to the left. So for example, for 5% it it 5.. when you bring the decimal two places to the left it becomes .05

We start with $371.93 then we multiply each percentage successively to this number

we work backwards

so we start with 5%

$371.93= .95 x X

X=$391.51

Then we take X and do the same process for 10%

$391.51= .90 x Y

Y = $435.01

again we take Y and do the same process for 25%

$435.01= .75 x Z

Z = $580.01

so the original price is $580.01

to find the total percent discount you take the total discounted price ($371.93) divided by the original price ($580.01) then you have 1 subtracted by the number. Finally, you multiply the number by 100 to change it to a percentage

so it's $371.93/$580.01 which = .64125

1 - 64125 = .35875 x 100= 35.88%

so your total percent discount is 35.88%

Hope this helps
