Answer:

B. h = 7.4 inches

Step-by-step explanation:

height of the laptop screen = h

d = 12.1 in.

w = 9.6 in.

We are given the formula,

d = √(w² + h²)

Plug in the values and solve for h

12.1 = √(9.6² + h²)

Square both sides

12.1² = 9.6² + h²

146.41 = 92.16 + h²

146.41 - 92.16 = h²

54.25 = h²

√54.25 = h

7.4 = h (nearest tenth)

h = 7.4 inches

Witch value from the set {3,8,9,14} makes the euation true 2n-5=
lutik1710 [3]

The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

2n - 5 = 11

When n = 3:

2(3) - 5 = 1 ≠ 11

When n = 8:

2(8) - 5 = 11

When n = 9:

2(9) - 5 = 13

When n = 14:

2(14) - 5 = 23

The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

I need to know exactly how to write "find the equation of the line below"
MAVERICK [17]

Answer:

y = -4/5x + 14/5

Step-by-step explanation:

Point (6,-2) and (-4,6)

Slope = (6- - 2) / (-4-6) = 8 / -10 = - 4/5

(The slope is negative because La línea is going downhill. Uphill is positive)

You can also find the slope in the graph: rise/run.

y-intersect (any point)

Point (6, -2) (any point)

y-Intercept: -2 - (-4/5)(6) = -2 + 24/5 = 14/5

Solve for x. Round to the nearest tenth of a degree, if necessary.
kakasveta [241]

Answer:

x ≈ 52.1°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{KL}{LM} = \frac{36}{28} , then

x = tan^{-1} (\frac{36}{28} ) ≈ 52.1° () to the nearest tenth )

Find AB when given angle B 64 degress angle C 75 degrese and side a 19
jeka94

Answer:

about 28

Step-by-step explanation:

you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)

AB = 19* (sin 75/ sin ( 180 -75-64) )

AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...
