Answer:
She has to cut another piece = 7.75 inches
Total length = 4x + 7.75
This is what y represent, so
y = 4x + 7.75
The graph of the equation is continuous
Answer:
A
Step-by-step explanation:
2x/x-1
Parent Function: f(x) = x^2
Right 2 units: f(x) = (x^2 - 2)
Down 4 units: f(x) = (x^2 - 2) - 4
Reflection over x-axis: f(x) = - (x^2 -2) + 4
Answer: f(x) = - (x^2 -2) + 4
Answer: Sin0 = 8/8.5
Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).
The Sine of the angle is calculated as
Sin0 = opposite/hypotenuse
We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.
To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,
X² = 3² + 8²
X² = 9 + 64
X² = 73
Adding the square root sign to both sides of the equation, we now have
X = √73
X = 8.5 (approximately)
Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as
Sin0 = opposite/hypotenuse
Sin0 = 8/8.5
