Answer:

x=14

Step-by-step explanation:

Adding all angles in this diagram sould get you 360. Because of this, we can use inverse operations to solve this. Subtract 90 and 60 from 360 to get 210. Now, the equation is 15x=210. Dividing both sides by 15 gets you 14. Hope this helps!

A circle with a radius of 4 in. is dilated by a scale factor of 1/2
Lunna [17]
Radius after dilation = 4 * 1/2 = 2 in

Now, C = 2πr
C = 2π(2)
C = 4π
Or C = 4 * 3.14 = 12.56

In short, Your Answer would be 4π or 12.56 in

Hope this helps!

Solve for t. d=−16t2+4t t=12±41−4d‾‾‾‾‾‾√ t=8±1−4d‾‾‾‾‾‾√ t=18±1−4d√8 t=12±41−4d√2
dangina [55]

Answer:

t=\dfrac{1}{8}\left(1\pm\sqrt{1-4d}\right)

Step-by-step explanation:

Rearranging your quadratic to standard form, you get ...

16t^2 -4t +d = 0

For the quadratic formula, you have ...

a = 16

b = -4

c = d

so the solution is ...

t=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(16)(d)}}{2(16)}=\dfrac{4\pm 4\sqrt{1-4d}}{32}\\\\t=\dfrac{1}{8}\left(1\pm\sqrt{1-4d}\right)
