Answer:
59.04°
58.31 inches
Step-by-step explanation:
The solution triangle is attached below :
Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;
Let the angle = θ
Tanθ = opposite / Adjacent
Tanθ = 50/30
θ = tan^-1(50/30)
θ = 59.036°
θ = 59.04°
The length of ladder can be obtained using Pythagoras :
Length of ladder is the hypotenus :
Hence,
Hypotenus = √(adjacent² + opposite²)
Hypotenus = √(50² + 30²)
Hypotenus = √(2500 + 900)
Hypotenus = 58.309
Length of ladder = 58.31 inches
Answer:
B
Step-by-step explanation:
The slope is -3/7. Use the point-slope form to write the equation.
(y-8)=-3/7(x-5)
<u><em>Answer:</em></u>

We know that the initial value of a function is the output of the function when the input is zero.
In other words, it is the value of f(x) when x = 0
<u>Now, checking the given table, we can find that:</u>
at x = 0 ...............> f(x) = 
<u>This means that</u> the output is when the input is zero which means that our initial value is
Hope this helps :)
We are basically given most of what we need to calculate the height of the cannonball.
We use the formula h = –16t+ vt + s to find the height requested.
Let v = 160
Let s = 10
Let t = time in seconds
Was the value of t included? We need to know t to plug into our formula.
You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.
