Answer:
Hence, Grasshopper will land on the ground after 1.5 sec.
Step-by-step explanation:
It s given that:
The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:
Now we are asked to find:
In how many seconds will the grasshopper land on the ground?
i.e. we have to find the value of t such that h(t)=0
i.e.
i.e. we need to find the roots of the given quadratic equation.
On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:
As time can't be negative hence we will consider:
Hence, grasshopper will land on the ground after 1.5 sec.
Answer : The number of larvae is greatest at 5 degrees Celsius.
Given the equation
x is the temperature of water in degrees Celsius, and y is the number of insect larvae in the water
Peak of the graph is the vertex
Now we find out the vertex from the given equation
To find x coordinate of vertex we use formula x=
a= -2, b= 20
So x=
x =
x = 5
Now we find out y
Plug in 5 in the place of x
y= 450
Vertex is (5,450)
It means the number of larvae reaches the maximum of 450 at 5 degree Celsius
Hence , the number of larvae is greatest at 5 degrees Celsius.
C is the answer bc its (5)^2-10(5)+25 so then it is 25-50+25 which = 0
The true statement is : Line p must be drawn so that it can lie on the same plane as line l
Step-by-step explanation:
From the diagram line l lies on plane A. When line p is drawn to be parallel to line l, it has to appear on plane A. This means that line p will be parallel to line l and perpendicular to line n that lies on plane B
