Answer:
C. 1,297,956 square ft.
Step-by-step explanation:
480.6*755.9*1/2 (area of triangle)
4 triangles so the above x4
square base=755.9^2
add it all together to get 1,297,955.89 or about 1,297,956
The length of the latter would be 23 feet because we know one angle is 75 and the angle against the wall is 90 and the base is 6 feet answer is 23 feet
Answer:
1)Yes
2)No
Step-by-step explanation:
1) 3x^2 = -27
3 (-3)^2 = -27
Once you substitute your value in for x, you can follow the rule <u>PEMDAS</u> to solve the equation.
3 (-9) = -27
-27 =-27
2) 10 - 5x = y
In an ordered pair, the first number is x and the second number is y.
10 - 5 (-4) = 10
10 - 20 = 10
-10 = 10
-10 ≠ 10
PEMDAS: A rule that states solving an equation by the order of operations:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

Step-by-step explanation:
Key features
when t = 0
the initial height is 143/3 = 47⅔ ft
initial velocity is -310/3 = -103⅓ ft/s (downward)
initial acceleration is 2(64) = 128 ft/s² (upward)
I would not like to ride this roller coaster!
that's about four times the acceleration of gravity, and it only increases as the car gets to the bottom of the curve at t = 1 s
For part 3
I'm not sure what they mean by "not realistic"
while the initial acceleration is high. the acceleration at t = 1 is zero except that in 'reality' the car would have to be going through a curve to change direction from down to up. That would create very high centripetal acceleration and therefore centripetal forces.
