Find BC

The graphic says find BC and it says BC = 33 feet
Anyway, assuming the ladder is 34 feet, and makes an 82 degree angle,
cosine 82 degrees = adjacent / hypotenuse
adjacent = cosine 82 degrees * hypotenuse
adjacent = 0.13917 * 34
adjacent (or side BC) = <span> <span> <span> 4.73178 </span> </span> </span> feet

height (line AB) = sine (82 degrees) * hypotenuse (34 feet)
height (line AB) = 0.99027 * 34
height (line AB) = 33.67 feet

If the bottom side is ab then bc is <span>8.18535277, which to the nearest tenth is 8.2

The carefully measure out the ingredients to make their pies each pie they make has 5.33 cups of apples in the filling how many

Ivahew [28]

Answer: 31.98 cups

Step-by-step explanation:

if there's 5.33 cups in 1 pie

then there is x cups in 6 pies.

set up a proportion:

5.33 cups = 1 pie

x cups = 6 pies

<em>cross multiplication.</em>

31.98 = x

therefore there are 31.98 cups of apples in 6 pies.

Find an equation of the tangent plane to the given surface at the specified point. z = ln(x − 8y), (9, 1, 0)

Archy [21]

Answer:

x - 8y - z = 1

Step-by-step explanation:

Data provided according to the question is as follows

f(x,y) = z = ln(x - 8y)

Now the equation for the tangent plane to the surface

For z = f (x,y) at the point P $(x_0,y_0,z_0)$ is

$z - z_0 = f_x(x_0,y_0)(x-x_0) + f_y(x_0,y_0)(y-y_0)\\$

Now the partial derivatives of f are

$f_x(x,y) = \frac{1}{x-8y} \\\\f_y(x,y) = \frac{8}{x-8y} \\\\P(x_0,y_0,z_0) = (9,1,0)\\\\f_z(9,1,0) = (\frac{1}{x-8y})_^{(9,1,0)}$

$\\\\=\frac{1}{9-8}$

= 1

Now

$f_y(9,1,0)=(\frac{8}{x-8y})_{(9,1,0)}\\\\ = -\frac{8}{9 - 8}$

= -8

So, the tangent equation is

$z - 0 = 1\times (x - 9) -8\times (y - 1)$

Now after solving this, the following equation arise

z = x - 9 - 8y + 8

z = x - 8y - 1

Therefore

x - 8y - z = 1

It's A since tangent is just opposite over adjacent, 12 is the opposite and 5 is the adjacent
