Trigonometry Problem, only solve if you know how and can tell me how to solve it.

Crazy boy [7]

The distances from the point the plane leaves the ground are given by the

trigonometric relationships of right triangle and Pythagoras theorem.

A) The minimum distance to the base of the tower is approximately 874.57 ft.

B) The minimum distance to the top of the tower is approximately 882.76 ft.

Reasons:

A) The angle with which the airplane climbs, θ = 11°

Height of the tower which the airplane flies, T = 120 foot

The clearance between the tower and the airplane, C = 50 feet

Required:

The minimum distance between the point where the plane leaves the ground and the base of the tower, $\displaystyle d_{min}}$

Solution:

Height at which the plane flies over the tower, h = T + C

Therefore, h = 120 ft. + 50 ft. = 170 ft.

At the point the plane leaves the ground, we have;

$\displaystyle tan(\theta) = \mathbf{\frac{h}{d_{min}}}$

Which gives;

$\displaystyle tan(11^{\circ}) = \frac{170 \, ft.}{d_{min}}$

$\displaystyle d_{min} = \mathbf{\frac{170 \, ft.}{tan(11^{\circ})}} \approx 874.57 ft.$

The minimum distance between the point where the plane leaves the ground and the base of the tower, $\displaystyle d_{min}}$ ≈ 874.57 ft.

B) The minimum distance between the point where the plane leaves the ground and the tower, R, is given by Pythagoras's theorem as follows;

R² = $\displaystyle \mathbf{d_{min}}}$ ² + T²

Which gives;

R = √(*874.57 ft.)² + (120 ft.²)) ≈ 882.76 ft.

The distance from the point where the airplane leaves the ground to the tower, R ≈ 882.76 ft.

Kevin uses 2 and 1/4 cups of ravens for every half cup of peanuts when making a snack mix how many cups of raisins does Kevin us

Dmitrij [34]

Answer:

For 1 cup of peanut Kevin will use $\frac{9}{2} \ cups \ \ \ OR \ \ \ 4\frac{1}{2} \ cups$ of raisins.

Step-by-step explanation:

Given:

$\frac{1}{2}$ cups of peanuts = $2\frac{1}{4}$ cups of raisin

$2\frac{1}{4}$ can be rewritten as $\frac{9}{4}$

$\frac{1}{2}$ cups of peanuts = $\frac{9}{4}$ cups of raisin

We need to find number of cups of raisins used in 1 cup of peanut.

Solution:

Now we know that;

$\frac{1}{2}$ cups of peanuts = $\frac{9}{4}$ cups of raisin

So 1 cup of peanut = number of cups of raisins used in 1 cup of peanut

Now by using Unitary method we get;

number of cups of raisins used in 1 cup of peanut = $\frac{\frac{9}{4}}{\frac{1}{2}}=\frac{9}{4}\times \frac{2}{1} = \frac{9}{2} \ cup \ \ \ OR \ \ \ 4\frac{1}{2} \ cup$

Hence For 1 cup of peanut Kevin will use $\frac{9}{2} \ cups \ \ \ OR \ \ \ 4\frac{1}{2} \ cups$ of raisins.

Which expression is equivalent to 4(x+2)

Alekssandra [29.7K]

Answer:

$4x+8$

Step-by-step explanation:

We have been given an expression $4(x+2)$ . We are asked to find equivalent expression to our given expression.

Using distributive property $a(b+c)=ab+ac$ , we will get:

$4\cdot x+4\cdot2$

$4x+8$

Therefore, the expression $4x+8$ is equivalent to our given expression.

Lines a and b are perpendicular. The equation of line a is y=1/3x+3. What is the equation of line b

kykrilka [37]

Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4
