Answer:

B and C are functions but A and D are not

Step-by-step explanation:

Vertical line testing. You draw a vertical line. If the vertical lines passes through one line, its a function. It it passes through more than one line, its not. Or in other words, each input (x-value) has its own output (y-value)

You are using extension ladders to paint a chimney that is 33 feet tall. The length of an extension ladder ranges in 1 foot inte
Alexus [3.1K]

Answer:

The ladder has to be 65 feet long to the nearest foot.

Step-by-step explanation:

The height of the chimney from the ground is the sum of the height of the wall and the height of the chimney.

Therefore, the height of the chimney from the ground = (30 + 33) = 63 feet.

Now, the ladder makes a right triangle with the ground and the chimney and the ladder makes an angle of 75.5° with the ground.

Therefore, using trigonometry we can write,

\sin 75.5 ^{\circ} = \frac{\textrm {The height of the chimney from the ground}}{\textrm {Length of the ladder}} = \frac{63}{\textrm {Length of the ladder}}

⇒ The length of the ladder = 65 feet.

Hence, the ladder has to be 65 feet long to the nearest foot. (Answer)

Answer:


Alternative C


Step-by-step explanation:

x² + 10x + 24 = 0

∆ = 10² - 4.1.24

∆ = 100 - 96

∆ = 4

x' = \frac{- 10 + 2}{2} \\\\\ x' = - 4 \\\ x" = \frac{- 10 - 2}{2} \\\\\ x" = - 6

The base of a triangle exceeds the height by 4 inches. if the area is 178.5 square inches, find the length of the base and the h
Elanso [62]
A = 1/2 * b * h
A = 178.5
b = h + 4

178.5 = 1/2 * (h + 4) * h
357 = h^2 + 4h
h^2 + 4h - 357 = 0
(h - 17)(h + 21) = 0

h - 17 = 0
h = 17

h + 21 = 0
h = -21 .....not this one because it is negative

b = h + 4
b = 17 + 4
b = 21

so the height is 17 inches and the base is 21 inches <==
