Answer:
The ladder reach a height 8.485 ft.
Step-by-step explanation:
The ladder with the building made right angle triangle
The length of the ladder is the hypotenuse 12 ft.
The angle between the ladder and the building is 45°
The height of the ladder reach is the vertical side of the Δ
∴ h = 12 cos 45° = 6√2 = 8.485 ft.
You write it in verbal expression so 1) 16 less than T is 39 2) product of 2 and w 3) the sum of v and 12 is 30 4) 8 more than w 5) the sum of n and 8 is 47
Answer:
a ≈ 8.9
Step-by-step explanation:
Set up the equation as so:
8a^2 + 2 = 634
First, subtract two from both sides:
8a^2 = 632
Then, divide by 8 to further isolate the variable.
a^2 = 79
To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9
Answer:
x = 0 AND x = -1
Step-by-step explanation:
You find the solution by finding where the two graphs meet. Then you can pull the x-coordinate off the points of intersection which is at 0 and -1
