Answer:
(9/2,0) and (0,-1)
Step-by-step explanation:
y(0) = log(1)-1 = -1
y=0 when log(2x+1) = 1
2x+1 = 10
x = 9/2
C I think I hope I’m right but it should be c
Answer:
The equation of the line is 
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(the value of y when x = 0).
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Line perpendicular to y = 4x + 4.
This line has slope 4, so our line will have slope:


So

Through (0, -3)
This means that 
So

Answer:
1 & 2 = Right Triangles
3 & 4 = Not Right Triangles
Step-by-step explanation:
Solved Using Pythagorean Theorem:
1)
= 225
= 225
2)
= 1521
= 1521
3)
= 776
= 784
4)
= 244
= 256
Option B: 1.6 s.
Although the equation is not included, you can obtain it by physical considerations
H(t) = -16.t^2 + 52t + 16
The maximum point is at the vertex and the vertex is in the middle of the roots.
The roots are when H(t) = 0,
So you have to solve 0 =-16t^2 + 52t + 16
Use the quadratic formula and you will find t = 3.53 and t =-0.28
Then the vertex is at the middle point = (3.53 -.028)/2 =1.63 s and the answer is option B: 1.6 s.
