Answer:

Part A: 3x + 36 = 180

Part B: x = 48

Step-by-step explanation:

A straight line is equal to 180 degrees. Knowing this, both 3x and 36 should be equal to 180. Write an equation:

3x + 36 = 180

Solve the equation:

3x + 36 = 180

Subtract 36 from both sides

3x = 144

Divide both sides by 3 to isolate the variable

x = 48

Check your work:

3(48) + 36 = 180

144 + 36 = 180

180 = 180

Correct

Using the equation representing the height of the firework (h = -16t2 + v0t + h0), algebraically determine the extreme value of
lubasha [3.4K]
-16t^2 + v0t + h0

=  -16(t^2 - 1/16 v0t)  + h0
 = -16 [(t - 1/32v0)^2 - (1/32 v0)^2 ) + h0
 = -16(t - 1/32v0)^2 + 1/64 (v0)^2 + h0   which is the vertex form 

The vertex  is at the point (1/32v0, 1/64 (v0)^2)

1/32v0  represents the time  when the firework is at its maximum height and 1/64 (v0)^2  is this maximum height

Does this graph show a function? explain how you know.
mina [271]
ANSWER

Yes,the graph passes the vertical line test.

EXPLANATION

The graph above shows a function because if we draw a vertical line across the graph anywhere, it will never intersect the graph more than once.

This is what we call the vertical line test.

Since the graph of the function passes the vertical line test, the graph shows a function.

See graph

Therefore the correct answer is option C.

Pls help it is due very soon.
Alexeev081 [22]

Answer:

AC = √105 ≈ 10 cm (nearest whole number)

Step-by-step explanation:

Use Pythagoras' Theorem: a² + b² = c²

(where a and b are the legs, and c is the hypotenuse of a right triangle)

Give one of the legs = 4cm and the hypotenuse = 11 cm:

⇒ 4² + AC² = 11²

⇒ 16 + AC² = 121

⇒ AC² = 121 - 16

⇒ AC² = 105

⇒ AC = ±√105

As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
