Answer:
Zeros:
Interception with y-axis
Vertex:
(-1, -2)
Step-by-step explanation:
We have the following quadratic function
To find the zeros of the function, make and solve for the variable x
We must factor the expression. Then we use the quadratic formula:
For a function of the form the quadratic formula is:
In this case note that:
Then:
We know that the vertex of a quadratic function is at the point:
Then:
The vertex is: (-1, -2)
The intersection with the y-axis we find it doing and solving for y
Look at the attached image.
Answer:
r=11inches v=968inches
Step-by-step explanation:
i just got it correct on a lesson :)
Notice how the x-2 on the numerator and denominator cancel out, as well as the x+1. You are left with 8(x+2)/4 which is 2(x+2) which results in your answer, B, or 2x+4.
Answer:
8.4 is 10% of 100
Step-by-step explanation:
84 is 100%
x is 10 %
x= 84*10/100= 8.4
