<u>Given</u>:

Given that HIJ is a right triangle.

The measure of ∠J is 90°, JI = 5, IH = 13, and HJ = 12.

We need to determine the value of sine of ∠H

<u>Value of sine ∠H:</u>

The value of sine ∠H can be determined by using the trigonometric ratios.

Thus, we have;

sin \ H=\frac{JI}{IH}

Substituting the values, we get;

sin \ H=\frac{5}{13}

Dividing, we get;

sin \ H=0.3846

Taking sin^{-1} on both sides, we have;

H=sin^{-1}(0.3846)

H=22.6189

Rounding off to the nearest hundredth, we get;

H=22.62^{\circ}

Thus, the measure of ∠H is 22.62°

Which sentence can represent the inequality One-half x + three-fourths greater-than-or-equal-to 5 and one-fourth?
hodyreva [135]

Answer:

  The sum of half of a number and three-fourths is at least five and one quarter

Step-by-step explanation:

It's all about making sense of an English sentence.

  "half the sum ..." is different from "the sum of half ..."

And ...

  "at least" and "not less than" mean the same (≥)

  "not more than" and "at most" mean the same (≤)

_____

Since all of the expressions are written out in words, it is a matter of matching the ideas expressed. That's a problem in reading comprehension, not math.

__

"One-half x + three-fourths [is] greater-than-or-equal-to 5 and one-fourth"

  means the same as ...

"The sum of half of a number and three-fourths is at least five and one quarter"

A searchlight is shaped like a paraboloid of revolution. If the light source is located 2 feet from the base along the axis of s
zhenek [66]

Answer:

3 ft.

Step-by-step explanation:

We have that the parabola formula has the following general equation:

x ^ 2 = 4py

p would come being the distension of the vertex until the focus.

They tell us that this value is 3, that is to say p = 3. Replacing we have:

x ^ 2 = 4 * 3 * y

x ^ 2 = 12 * y

reorganizing for and, we are left with:

y = (1/12) * x ^ 2

We know that the opening is 12 feet wide, therefore, the parabola, being symmetry, must be distributed in the same way, in two equal parts, that is, 12/2 = 6. Therefore, being vertical on the x axis must take values of (-6, y), (6, y).

Which means that the value of x is 6 or -6. (it doesn't matter which of the two is when it is squared)

Replacing in the equation obtained:

y = (1/12) * (6 ^ 2)

y = 3

Therefore the depth is equal to 3 ft.

daser333 [38]
The metric table goes millimeters, centimeters, decimeters, meters, dekameters, hectometers, kilometers. To move up the table, move the decimal point one to the left. If you wanted to change it to centimeters, the answer would be 8,340,000. In kilometers, this is 83.4 kilometers. Hope this helps!

At 2 hours before sunset, the temperature is 0°F. At 2 hours after sunset, the temperature is −4°F. Identify the slope, y-interc
Flauer [41]

Answer:

Slope = -1

y = -2 --- y intercept

x = -2 ---- x intercept

y = -x - 2 --- equation

Step-by-step explanation:

Given

Represent temperature with y and time with x

When

y = 0F; x = 2hrs\ before\ sunsets

y = -4F; x = 2hrs\ after\ sunset

Solving Slope;

Slope = \frac{y_2 - y_1}{x_2 - x_1}

Slope = \frac{-4 - 0}{2 - (-2)}

Slope = \frac{-4 - 0}{2 +2}

Slope = \frac{-4}{4}

Slope = -1

Using

Slope = \frac{y - y_1}{x - x_1}, we can get the equation

Where

Slope = -1

x_1 = -2

y_1 = 0

This gives:

-1 = \frac{y - 0}{x -(-2)}

-1 = \frac{y}{x +2}

Cross multiply

y = -x - 2

Take x as 0; to solve the y intercept

y = -0 - 2

y = -2

Take y as 0; to solve the x intercept

0 = -x -2

x = -2
