Answer:
I know #1 but not #2 it's
(10x2)+4=24 it's still less then 25 :)
Answer:
The equation of the quadratic function shown is;
x^2+ 2x -3
Step-by-step explanation:
Here in this question, we need to know the quadratic equation whose graph was shown.
The key to answering this lies in knowing the roots of the equation.
The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.
The graph crosses the x-axis at two points.
These are at the points x = -3 and x = 1
So what we have are;
x + 3 and x -1
Multiplying both will give us the quadratic equation we are looking for.
(x + 3)(x-1) = x(x -1) + 3(x-1)
= x^2 -x + 3x -3 = x^2 + 2x -3
Answer:
Raquel should adjust the number of rotations to 115.81 rotations
Step-by-step explanation:
step 1
Find the circumference of the wheels that are 2.5 cm in diameter
The circumference is equal to
we have
assume
substitute
step 2
Find the number of rotations
Divide 10 meters by the circumference
step 3
For a diameter of 2.75 cm find how should she adjust the number of rotations so that the robot travels the same distance
Find the circumference of the wheels
The circumference is equal to
we have
assume
substitute
step 4
Find the number of rotations
Divide 10 meters by the circumference
la neta lo a mirado pero se me olvido if I'm right I think it' c
This would be the identity property of addition telling us that any number added to zero is that number (i.e. 6 added to zero is still 6)
