Answer:
The correct answers are:
- -90
- -100
- +2
Step-by-step explanation:
- As sea level is equal to zero, 90 feet below sea level is -90 ft. The integer is -90.
- As debts are consider negative in a balance, $100 of debt are -$100. The integer is -100.
- As 0°C is the zero of the Celcius scale, 2°C above zero is +2°C. The integer is +2.
Answer:
B
Step-by-step explanation:
Chords which intersect have segments whose products are equal. This means the chord with lengths 5 and x has a product 5x. It is equal to the the other chords lengths 5.1 and 9 as a product 5.1*9.
5x = (5.1)(9)
5x = 45.9
x = 9.18
9.18 rounds to the tenth place as 9.2
It will reach the maximum in 1 second; the maximum height is 22 feet.
We find the maximum by finding the vertex. We first find the axis of symmetry, whose equation is
x = -b/2a
x = -32/2(-16)
x = -32/-32 = 1
This gives us that it reaches the maximum in 1 second.
To find the y-coordinate, the maximum height, we substitute this into the equation:
h(1) = -16(1²)+32(1)+6
h(1) = -16+32+6 = 22
It reaches a height of 22 feet.
