Answer: |h-1.7| \le 0.5

==========================================================

Explanation:

The endpoints of this compound inequality are 1.2 and 2.2

Add up the endpoints to get 1.2+2.2 = 3.4

Divide that result in half getting 3.4/2 = 1.7

The midpoint between 1.2 and 2.2 is 1.7

The distance from 1.7 to 1.2 is 0.5 units after we subtract the values (1.7-1.2 = 0.5). Also, from 1.7 to 2.2 is 0.5 units as well (2.2 - 1.7 = 0.5)

The compound inequality 1.7 \le h \le 2.2 converts to the absolute value inequality |h-1.7| \le 0.5

The portion h-1.7 represents the distance h is from 1.7; we want this distance to be 0.5 or smaller. The use of absolute value is to ensure the result h-1.7 is never negative.

What is the slope of this line?
alisha [4.7K]

Answer:

A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .

A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .

If a line is horizontal the slope is zero. This is a constant function.

If a line is vertical the slope is undefined (see below).

Answer: 33.85 mm

Step-by-step explanation:

Use trigonometry, tan equation

You are give the tan angle and adjacent side, you need to find the opposite side so

O

T A

Tan(72)= x/11

x= tan(72) x 11

x= 33.85

A kite flier wondered how high her kite was flying. She used a protractor to measure an angle of 15∘ from level ground to the ki
Nataly [62]

Answer:

12.9 yd

Step-by-step explanation:

It helps if you draw a triangle. Draw a horizontal segment. That is the ground. Now at the left end start a new segment that goes up to the right at approximately 15 degrees until it its other endpoint directly above the right endpoint of the horizontal segment. Connect these two endpoints. The vertical side on the right shows the height of the kite. The hypotenuse is the string.

For the 15-deg angle, the height of the triangle is the opposite leg, and the string is the hypotenuse. The trig ratio that relates the opposite leg tot he hypotenuse is the sine.

\sin A = \dfrac{opp}{hyp}

\sin 15^\circ = \dfrac{h}{50~yd}

(50~yd)\sin 15^\circ = h

h = (50~yd)(0.2588)

h = 12.9~yd
