1/2 * n = 2n + 14

Multiply everything by 2 to get rid of the fraction

n = 4n + 28

n - 4n = 28

-3n = 28

n = -9.333333

n = -28/3

11) A building casts a shadow of 100 feet. The angle of elevation from the end of the shadow to the top of the
svp [43]

Answer:

≈ 27 ft

Step-by-step explanation:

using the tangent ratio in the right triangle formed by the building and the ground.

tan15° = \frac{opposite}{adjacent} = \frac{?}{100} ( multiply both sides by 100 )

100 × tan15° = ? , then

? ≈ 27 ft ( to the nearest whole number )

Taylor is making a mini apple pie with a radius of 3.14 in for her math class. what is the area of her mini pie?
artcher [175]

So First of all we need to know how to find the area of a circle.

Assuming that the apple pie is the shape of a circle

The formula for area is \pi r^{2}

Well we know that the radius = 3.14

And we know that \pi = 3.14 as well.

All we have to do is multiply..

3.14 x 3.14^{2} = 30.95

So the area of the pie is 30.95 in


Good Luck! :)

A rectangle initially has dimensions 6 cm by 7 cm. All sides begin increasing in length at a rate of 1 cm/s. At what rate is the
Morgarella [4.7K]

Answer:

  49 cm²/s

Step-by-step explanation:

The problem statement tells you what to do.

Write an equation relating A, b, h:

  A = bh . . . . . . the equation for the area of a rectangle

Differentiate with respect to t:

  dA/dt = (db/dt)h + b(dh/dt) . . . . . . . product rule

To find the rate of change after 18 seconds, you need to know the dimensions b and h after 18 seconds. Since each dimension was increasing at the rate of 1 cm/s, it is 18 cm more than it was at the beginning:

At 18 seconds,

  b = 6 cm + 18 cm = 24 cm;

  h = 7 cm + 18 cm = 25 cm.

Of course, db/dt = dh/dt = 1 cm/s. Then the rate of change of area is ...

  dA/dt = (1 cm/s)(25 cm) + (24 cm)(1 cm/s)

  dA/dt = 49 cm²/s

_____

You could write a formula for the area as a function of time and differentiate that:

  A = (6 +t)(7 +t) = 42 + 13t + t²

Then the derivative is ...

  dA/dt = 13 +2t

and when t=18, this is ...

  dA/dt = 13 + 2(18) = 49 . . . . cm²/s
