a wagon is pulled at speed of 40.0 m/s by a horse exerting 1800 newton horizonal force what is the power of horse
Sonbull [250]

Answer:

The power of horse is:  P = 72000 W

Step-by-step explanation:

Given

  • F = 1800 N
  • v = 40.0 m/s

To determine

P = ?

Using the formula

\:\:\:P=\overrightarrow{F\cdot }\overrightarrow{v}

The  ⋅  in the formula represents a scalar product, defined by:

\overrightarrow{v\cdot }\overrightarrow{w}=|v||w|cos\:\theta

The angle Ф is zero because F and v are are parallel.

Thus the cosine is 1.

Therefore,

P = (1800) (40.0)

P = 72000 W

Hence, the power of horse is:  P = 72000 W

The following frequency distribution shows the yearly tuitions (in $1,000s) of a sample of private colleges.
hoa [83]

Answer:

19.714

Step-by-step explanation:

Given :

Yearly Tuition Frequency

12-16 5

17-21 4

22-26 3

27-31 2

We calculate the midpoint (x) = (lower + upper) / 2

The mean yearly tuition :

The midpoint (x) :

X ___ F ___ Fx

14 __ 5

19 __ 4

24 __ 3

29 __ 2

The mean = Σfx / Σf

Σfx / Σf = (14*5 + 19*4 + 24*3 + 29*2) / (5+4+3+2)

Mean = 276 / 14

Mean yearly tuition = 19.714

If f(x) = x2 – 2x and g(x) = 6x + 4, for which value of x does (f + g)(x) = 0?<br> Х<br> оооо
Fittoniya [83]

Answer:

(f+g) (x) =0 for x=-2

Step-by-step explanation:

f(x) = x^2 – 2x, g(x) = 6x + 4,

(f+g) (x) =f(x) +g(x) =

(x^2 – 2x) + (6x + 4) =

x^2 – 2x+ 6x + 4=

x^2 +4x+4

(f+g)(x) =x^2 +4x+4=0 (quvadratic equation)

x^2 +4x+4=x^2 +2x*2+2^2=(x+2)^2

then

(x+2)^2 =0

x+2=0

x=-2

(f+g) (x) =0 for x=-2

two similar triangles have a scale factor of 3:5. the altitude of the larger trangle is 24 inches. what is the altitude of the s
Andreyy89
The altitude of the smaller triangle will be given as follows:
let the altitude of the smaller triangle be x
scale factor of small to large triangle is 3:5
but
scale factor=(length of small Δ)/(length of large Δ)
plugging in our values we get:
3/5=x/24
solving for x we get:
x=3/5×24
x=14.4 inches

Answer: 14.4 inches
