Answer:
Vertex (-2.5,-300)
Step-by-step explanation:
We are given with h(t)=-16 t^2 +80 t. We are asked to find the vertex.
X-coordinate of vertex =
Where 'a' is coefficient of 
term
'b' is coefficient of 't' term.
From given function, a= -16
b=80
So,
x-coordinate of vertex =
=-2.5
y-coordinate of vertex =
Simplify it,
=-100 -200
= -300
So, vertex is at (-2.5, -300).
Answer:
Step-by-step expThis is the concept of trigonometry, the value of x will be calculated as follows;
sin theta=[opposite]/[hypotenuse]
theta=x
opposite=16 units
hypotenuse=21 units
thus;
sin x=16/21
hence;
x=arcsin(16/21)
x=49.63
x=50 (to the nearest degrees)
The answer is 2 x10 = 20
To the power of b which is 15
Example:
5w - five apples
8 - eight strawberries
5w + 8 = (five apples) + (eight strawberries) = 13 of what?
You can add only numbers of the same fruits.
Answer:
46 logs on the 5th row.
Step-by-step explanation:
Number of logs on the nth row is
n = 50 - (n-1)
n = 51 - n (so on the first row we have 51 - 1 = 50 logs).
So on the 5th row we have 51 - 5 = 46 logs.
