Step-by-step explanation:

1 year = 12 months

2yrs = 24 months

F(c) =100+5(24)

= 100+120

= $220

The hour hand of a clock is 3 feet long. How many feet does

dem82 [27]

Answer:

2π feet

Step-by-step explanation:

9:30 PM to 1:30 AM is 4 hours.

It is 1/3 of a complete revolution.

A full 12 hours would be 2×r×π=2×3×π

1/3 of that is:

1/3×2×3×π=2π

≈6.283185307 feet

What is the answer of this problem if mr.reyes gave his daughter P250 on her 18th birthday and intends to increase this by P150

o-na [289]

28 - 18 = 10.
150 x 10 = 1500
So all you've got to do is..
150 x 1500 = ???

You can do the rest lol

20 POINTS!!!

choli [55]

Hello from MrBillDoesMath!

Answer:

x = 0, 7

Discussion:

f(g(x)) =

f ( x^2-7x) =

1/ ( x^2 - 7x)

The points NOT in the domain are those where the denominator, x^2 - 7x = 0.

x^2 - 7x = 0 => factor x from each term

x(x-7) = 0 => one or both terms must each 0

x = 0 or x =7

Thank you,

MrB

A discuss moves from P1 (4,8) to P2 (15,17). What is the lincar displacement in the horizontal and vertical directions? What is

Yakvenalex [24]

Answer:

The horizontal displacement is 11 units, the vertical displacement is 9 units, and the projection angle is 39.3 degrees.

Step-by-step explanation:

We can start using the definition of displacement in one dimension between any 2 points which is the difference between them, so we have

$\Delta s = s_2-s_1$

And apply it to get the horizontal and vertical displacements.

Once we have found them, we can use trigonometric functions to find the projection angle with respect the horizontal.

Linear displacements.

Using the definition of displacement, we can write the horizontal displacement as

$\Delta x = x_2-x_1$

So we can use the given points $P1:(x_1,y_2) \text{ and } P_2: (x_2,y_2)$ on the displacement formula

$\Delta x = 15-4\\\Delta x = 11$

In the same manner we can look at the y components of those points to find the vertical displacement

$\Delta y = 17-8\\\Delta y =9$

Thus the horizontal displacement is 11 units and the vertical displacement is 9 units.

Projection angle.

The projection angle with respect the horizontal is the angle that is made between the line that connects the points P1 and P2 and the horizontal, so we can use the linear displacements previously found to write

$\tan(\theta) = \cfrac{\Delta y}{\Delta x}$

Solving for the angle we get

$\theta = \tan^{-1}\left(\cfrac{\Delta y}{\Delta x}\right)$

Replacing values

$\theta = \tan^{-1}\left(\cfrac{9}{11}\right)$

Which give us

$\theta = 39.3^\circ$

So the projection angle is 39.3 degrees.
