Answer:

33,175.21/radians/sec

Step-by-step explanation:

22 rev/sec x 60sec/1 min x 4ft x2 pi/1 rev

22 x 60 = 1320

1320 x 4 = 5280

2 x pi = 6.2831853072

5280 x 6.2831853072= 33,175.218421884

Solve using the fundamental theorem of algerba
Olin [163]

Answer:

No. of x-intercepts is equal to the no. of distinct species factors of a polynomial

Since this curve has only one distinct factor i.e (x+7)

The only x-intercepts is -7

(-7,0)

Y intercept would be at (0+7)⁷

Which is (0,7⁷)

Or (0,823543)

Since it's an odd power, branch of the curve for x > 7 would approach positive infinity

Branch for x < 7 would approach negative infinity

A ramp 18 ft long rises to a platform. The bottom of the platform is 13 ft from the foot of the ramp. Find x, the angle of eleva
Varvara68 [4.7K]

Answer:

The answer to your question is: Ф = 43.95°

Step-by-step explanation:

Data

length = 18 ft

distance bottom to is 13 ft

x = angle = ?

Formula

cos Ф = opposite side / hypotenuse  

Process

cos Ф = 13 ft / 18 ft                   substitution

cos Ф = 0.72                            simplify

Ф = cos⁻¹ (0.72)

Ф = 43.95°                                result

Makovka662 [10]
Area de la base es un hexagono: Nota: asumiendo que 39 cm son el lado de un hexagono. Menuda pizza.

A = 3*sqrt(3)/2*a^2 = 3*sqrt(3)/2*39^2 = 3951.67391746839972 cm^2

Hay dos base y tapa, doble:

7903.34783493679944 cm^2

Luego los lados verticales:

6 * 39 * 4.7 = 1099.8 cm^2

TOtal = 9003.14783 = 9003.147 cm^2 = 9003.15 cm^2
