Plug -1 into the equation.
F(x)=(-1)5+(-1+3)2
F(x)=-5+4=-1
Your answer is -1
The total cost is 15.75
explanation: 5 percent of 15 is .75 plus the initial cost of 15 equals 15.75
You simply try put the whole example in an equation form.
vc= velocity of car
vp= velocity of the plane
know it is given that the time of both travels is the same, and using the famous velocity time equation you can say,
t=(distance by the car/vc)=(distance by the plane/vp)
so
(150/vc)=(600/vp)
Now, given that vp=150+vc
We have;
(150/vc)=(600/150+vc)
multiply and you get an equality of
150(150+vc)=600vc
150^2+150vc=600vc
make all vc at one side, you have;
150^2=600vc-150vc
then; vc=150^2/450=50
and use the vp=150+vc equation again and you get,
vc=200mph.
Hope this helps.
Answer:
84.78
Step-by-step explanation:
The full area of the circle without the cutout is 113.04
The cutout sector is 28.26
So that would make our final answer 84.78
by subtracting 28.26(cutout) from 113.04(full circle)
(In case you are wondering) The way I found the cutout sector's area was this formula: π4²·(angle)/360
Answer:
<C =120
Step-by-step explanation:
Since the figure in inscribed in the circle, <A = <C and <B = <D
<B= <D
2x-1=3x-59
Subtract 2x from each side
2x-2x-1=3x-2x-59
-1= x-59
Add 59 to each side
-1+59 = x-59+59
58 =x
<A = 2x+4
<A= 2(58) +4
= 116+4
<A =120
<C = <A
<C =120
