Answer:

2x+5y=-15

ax+bx=c

slope=-a/b so -2/5 matches up with point slope form

then to get y intercept substitite x in point slope for 0 and solve for Y to get -3

then do c/b to get y intercept, so -15/5, which equals -3.

a ferris wheel rotates 9pi/8 radians prior to making a stop the total height of the ferris wheel is 246 ft how far around did th

Zinaida [17]

Answer:

ferris wheel travel approx = 434.72 ft

Step-by-step explanation:

given data

wheel rotates = 9pi/8 radians

total height of the ferris wheel = 246 ft

solution

we can say here that height of the ferris wheel is same as the diameter of the wheel

and wheel is circular in shape

so we get here first radius of wheel that is

radius = half of diameter ..........................1

put here value and we get

radius = 0.5 × 246

radius = 123 ft

and

wheel travel distance = length of arc by a angle of wheel rotates

so here length of arc will be

arc length = radius × wheel rotates angle .....................2

put here value and we get

arc length = 123 × $\frac{9\pi }{8}$

arc length = 434.7178 ft

so ferris wheel travel approx = 434.72 ft

I need help with properties of rhombus, rectangles and squares

Montano1993 [528]

Answer:

∠ROK = 36°
∠CKO = 96°
∠C = 60°

Step-by-step explanation:

The same-side angles at each base are supplementary, so ...

∠ROC = 180° -120° = 60°

Because the trapezoid is isosceles, 60° also the measure of ∠C.

The angle sum theorem tells you ...

∠COK +∠ROK = ∠ROC

24° + ∠ROK = 60°

∠ROK = 36° . . . . . . subtract 24°

The sum of angles in ΔCKO is 180°, so ...

∠C +∠COK +∠CKO = 180°

60° +24° +∠CKO = 180°

∠CKO = 96° . . . . . . . . . . . . . subtract 84°
