Options :

Negative 2 and one-third meters

Negative three-fourths meters

Negative one-fourth meters

Negative 1 and

StartFraction 5 Over 6 EndFraction meters

Answer: Negative three-fourths meters

Step-by-step explanation:

Given the following :

Depth Location of Emerald :

Between - 1/2 and - 1 2/3

The answer will be the option which lies between the two depth points.

-1/2 = - 0.5 ( upper bound)

-1 2/3 = - 1.667 ( lower bound)

The option which lies inbetween :

- 1.667 and - 0.5

Taking each option :

Negative 2 and one-third meters = - 2 1/3 = - 2.33

Negative three-fourths meters = - 3/4 = - 0.75

Negative one-fourth meters = - 1/4 = - 0.25

Negative 1 and StartFraction 5 Over 6 EndFraction meters = - 1 5/6 = - 1.833

Hence, the only depth position which lies inbetween (-1.667 and - 0.5) is - 0.75

Answer:

15) The length of the line segment DE is 14.908.

16) The measure of the angle W is approximately 31.792°.

17) The length of the ladder is approximately 23.182 feet.

Step-by-step explanation:

15) We present the procedure to determine the length of segment DE:

(i) Determine the length of the line segment DF by trigonometric relations:

\tan C = \frac{DF}{CF} (1)

(C = 61^{\circ}, CF = 24)

DF = CF\cdot \tan C

DF = 24\cdot \tan 61^{\circ}

DF \approx 43.297

(ii) Determine the length of the line segment DE by trigonometric relations:

\tan F = \frac{DE}{DF} (2)

(DF \approx 43.297, F = 19^{\circ})

DE = DF\cdot \tan F

DE = 43.297\cdot \tan 19^{\circ}

DE \approx 14.908

The length of the line segment DE is 14.908.

16) We present the procedure to determine the measure of the angle W:

(i) Determine the length of the line segment XZ by trigonometric relations:

\sin Z = \frac{XY}{XZ} (3)

(XY = 15, Z = 25^{\circ})

XZ = \frac{XY}{\sin Z}

XZ = \frac{15}{\sin 25^{\circ}}

XZ \approx 35.493

(ii) Calculate the measure of the angle W by trigonometric relations:

\tan W = \frac{XZ}{WZ} (4)

(XZ \approx 35.493, WZ = 22)

W \approx \tan^{-1} \left(\frac{22}{35.493}\right)

W \approx 31.792^{\circ}

The measure of the angle W is approximately 31.792°.

17) The system form by the ladder, the ground and the wall represents a right triangle, whose hypotenuse is the ladder, which is now found by the following trigonometric relation:

\cos \theta = \frac{x}{l} (5)

Where:

\theta - Angle of the ladder above ground, in sexagesimal degrees.

x - Distance between the foot of the ladder and the base of the wall, in feet.

l - Length of the ladder, in feet.

If we know that x = 6\,ft and \theta = 75^{\circ}, then the length of the ladder is:

l = \frac{x}{\cos \theta}

l = \frac{6\,ft}{\cos 75^{\circ}}

l \approx 23.182\,ft

The length of the ladder is approximately 23.182 feet.

Help? ^-^ WILL GIVE BRAINLIEST!<br><br> What is the slope of a line through (1, 3) and (-2, 2)?
ryzh [129]

Answer:

<em>The slope of the line is </em>\frac{1}{3}<em />

Step-by-step explanation:

<u>The Slope of a Line </u>

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

It's given the points (1,3) and (-2,2). Let's calculate the slope:

\displaystyle m=\frac{2-3}{-2-1}

Calculating:

\displaystyle m=\frac{-1}{-3}

\displaystyle m=\frac{1}{3}

The slope of the line is \frac{1}{3}

(10x+8)°<br> (9x+18<br> x=8<br> (12x-10)
Brrunno [24]

Answer:

Step-by-step explanation:

(10x + 8)^0 = 1

(9x+18) if x = 8 = 9*8 = 72 + 18 = 90

12x - 10

12 * 8 = 96 - 10 = 86

(1) ( 90) ( 86)

if you need to multiply them them do so
