A rock is thrown down from a cliff that is 180 m high. The function
h(t) = -5t^2 – 10t + 180 gives the approximate height of the rock
above the water, where h(t) is the height in metres and t is the time
in seconds. When will the rock reach a ledge that is 105 m above
the water?
Answer:
t = 3
Step-by-step explanation:
105 = -5t^2 -10t + 180
-75 = -5t^2 -10t
15 = t^2 +2t
t^2 +2t -15 = 0
(t+5)(t-3)
t = -5, 3
There's no such thing as negative time so you use the positive answer
please help!! asap!!!
Solution:
Rewrite 3 ≥ y - 2 for easier calculation:
y - 2 ≤ 3
Move the term:
y ≤ 3 + 2
y ≤ 5
When graphing the solution, filled dot (black arrow) is used for ≤ and ≥ while empty dot (white arrow) is used for < >

A store down the street is selling a console 50% of from 236.87 if i were to buy the console wit my 490.45 how much money will i get back?
Answer:
$372.01
Step-by-step explanation:
50% of $236.87 is half of it, which means the console is being sold for $118.44 because:
235.87/2 = 118.435
Round this to the nearest cent:
$118.44
If you have $490.45, and you spend $118.44, it means that you subtract the cost from your own money:
490.45 - 118.44 = 372.01
You will have $372.01 left.

-4(3+n)>-32
Answer:
N<5
Step-by-step explanation:
-4(3+n) > -32
-4(n+3) > -32
-(4n + 4 x 3) > -32
-(4n + 12) > -32
(-4n - 12) +12 > -32 + 12
-4n - 12 + 12 > -20
-4n > -20

Using a graph of the function, determine which statement is NOT a true description
of this quadratic function.
Answer:
it will be 271 because u multiple
The maximum value that the function reaches is 0, which occurs at x = 6.
What is a Quadratic equation?ax²+bx+c=0, with a not equal to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Since a blank grid is given, we can plot the graph of the quadratic function f(x) = x^2 - 5x - 24 using the given points:
X: 10 -8 6 4 2 4 6 8 10
f(x): -116 -12 0 -8 -20 -8 0 8 24
The graph of the quadratic function looks like a parabola opening upwards, with the vertex at the point (2, -20).
Based on the graph, we can make the following observations:
The function has a minimum value of -20, which occurs at x = 2.The function is symmetric about the vertical line that passes through the vertex (2, -20).The function intersects the x-axis at x = -3 and x = 8.The function intersects the y-axis at y = -24.Therefore, the statement that is NOT a true description of this quadratic function is:
"The function has a maximum value of 24, which occurs at x = 10."
This statement is not true because the function has a minimum value of -20 at x = 2, but it never reaches a maximum value of 24. The maximum value that the function reaches is 0, which occurs at x = 6.
