I'm ASSUMING this is a 45-45-90 right triangle and that DF is the hypotenuse.
With that said. Angle F = 45 means that angle  = 45 and angle E = 90 degrees.
There is only one rule for 45-45-90 right triangles:
 hypotenuse = √(2) * leg
Given the hyp = 16
16 = √(2) * leg
divide both sides by √(2)
16/√(2) = leg
Rationalize the denominator
16√(2)/(√(2)*√(2) =
(16√(2)) / 2 =
8√2

Stephen purchased a guitar, which was originally priced at $80 but discounted at 25%. He also had to pay 5% sales tax. What amou
nikdorinn [45]

Discounted by 25% means he paid 75% of the original price:

80 x 0.75 = $60

Now multiply the sale price by 1 + tax rate:

60 x 1.05 = 63

He paid $63 total.

The circumference of a circle is 6π inches. What is the area of the circle? Alternative Text A. 3π in.2 B. 9π in.2 C. 12π in.2 D
alukav5142 [94]

Answer:

B) 9π in^2

Step-by-step explanation:

Circumference of a circle is C = πD

Divide 6π by π to get 6 then divide by 2 to get the radius of the circle

Area of a circle is A = πr^2

6/2 = 3 3 = r

π(3)^2 = 9π

Step-by-step explanation:

Given equation of circle (in general form) is:

8 {x}^{2}  + 8 {y}^{2}  - 16x - 32y + 24 = 0 \\  \\ dividing \: throughout \: by \: 8 \: we \: find :  \\  {x}^{2}  + {y}^{2}  - 2x - 4y + 3 = 0  \\ equating \: it \: with :  \\  {x}^{2}  +  {y}^{2}  + 2gx + 2fy + c = 0 \\ 2g =  - 2 \implies \: g =  -  1\\  2f =  - 4 \implies \: f =  - 2 \\ c = 3 \\   \therefore \:center =  ( - g, \:  \:  - f) = (1, \:  \: 2) \\  \\ radius \: r =  \sqrt{ {g}^{2} +  {f}^{2}  - c }  \\  =  \sqrt{ {1}^{2}  +  {2}^{2}  - 3}  \\  =  \sqrt{1 + 4 - 3}  \\  =  \sqrt{5 - 3}  \\  =  \sqrt{2}  \: units
