Answer:

d. -2 <= y <= infinity

Step-by-step explanation:

The graph starts at -2 with a solid (colored in) point on the -2. So there are no y's less than -2 on the graph.

The graph continues to go up. Yes, it goes to the right, but we are looking at the y's. There is an arrow at the right end of the graph which means it continues to go up forever.

-2 <= y <= infinity

sin(theta) = 6/10 and theta is in the second quadrant. Use trigonometric identities to find the following quantities exactly.
---
sin = 3/5
=============
(a) cos(theta)
cos = sqrt(1 - sin^2) = -4/5 (negative in Q2)

-----
(b) sin(2theta) =
sin(2t) = 2sin(t)*cos(t) = -24/25 --> Q3
-----
(c) cos(2theta
cos(2t) = sqrt(1 - sin^2(2t)) = -7/25 (negative in Q3)
-----
(d) tan(2theta) = = sin(2t)/cos(2t) = 24/7 (+ in Q3)

A 10-foot ladder is leaning against a tree. The bottom of the ladder is 4 feet away from the bottom of the tree. Approximately h

strojnjashka [21]

Answer:

Step-by-step explanation:

If we were to draw a horizontal line from the bottom of the ladder to the bottom of the tree and then draw a vertical line from the bottom of the tree to the top of the ladder, we'd get a right triangle with legs as the distance between the bottom of the tree and the bottom of the ladder and the height of the ladder, and the hypotenuse is the length.

Here, we know the hypotenuse is 10 feet and that the bottom of the ladder is 4 feet away from the bottom of the tree, so use the Pythagorean Theorem to find the height:

h = $\sqrt{10^2-4^2} =\sqrt{84}$ ≈ 9.2 feet

The answer is C.

MULTIPLE CHOICE A thermometer is

pav-90 [236]

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

Thermometer accuracy = ±2°F
Thermometer reading = 17°F

The least possible value of temperature can be calculated thus :

Thermometer reading - thermometer accuracy

17 - 2 = 15°F

The highest possible temperature can be calculated thus :

Themometer reading - thermometer accuracy

17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
