Answer:

Step-by-step explanation:

f(x) = -4cos(3x-pi) +2

compare to f(x) = A cos (B(x+C))+D

A is amplitude =4

Period is 2pi/B so period = 2pi/3

Phase shift is C so phase shift = -pi (this could be positive if it shifted to the left)

Midline is at D so midline is y=2

Lubov Fominskaja [6]

Answer:

a) $4.14

b) No

c) 28 Snickers, 40 Milky Ways, 63 Reese's

72 Snickers, 60 Milky Ways, 37 Reese's

Step-by-step explanation:

Since 1 Snickers is $0.01, 1 Milky Ways is $0.03, and 1 Reese's is $0.04:

30 Snickers: 30(0.01) = 0.3

40 Milky Ways: 40(0.03) = 1.2

66 Reese's: 66(0.04) = 2.64

The value is: 0.3 + 1.2 + 2.64 = 4.14

The total value is: 1 + 3 + 4 = 8

A fair share must have the same value, 8/2 = 4. Since one half is 4.14 which is more than 4, it is not a fair share.

First half:

28 Snickers: 28(0.01) = 0.28

40 Milky Ways: 40(0.03) = 1.2

63 Reese's: 63(0.04) = 2.52

Second half:

72 Snickers: 72(0.01) = 0.72

60 Milky Ways: 60(0.03) = 1.8

37 Reese's: 37(0.04) = 1.48

A horizontal curve is being designed around a pond with a tangent length of 1200 ft and a central angle of 29.86 degrees. If the

Answer:

The correct answer is "1287.02 ft"

Step-by-step explanation:

Given that:

T = 1200 ft

PI = 145+00

$\Theta$ = 29.86°

or,

= 0.5211 rad

As we know,

The radius of curve is:

⇒ $T = R \ tan\frac{\Theta}{2}$

$1200=R \ tan(\frac{0.5211}{2} )$

$1200=R \ tan(0.267)$

$R = 4494.38 \ ft$

The length of curve will be:

⇒ $L=R \Theta$

$=449.38\times 0.5211$

$=2342.01 \ ft$

hence,

Station PT will be:

= $PI-T+L$

= $145-1200+2341.01$

= $1287.02 \ ft$
