Answer:
I think you’re correct
Step-by-step explanation:
Answer: 6 cm
Step-by-step explanation:
Use equation for area of triangle
A=a*h/2
a*h=2A
a=2A/h
where a represents base of triangle
h represents height of triangle.
h=12.8 cm
A=38.4 cm²
a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm= 6 cm
Answer:
(2,1) and (5,-5)
Step-by-step explanation:
I just truned it in and it was right.
The time it will take the thermometer to hit the ground is 22 seconds
<h3>Calculating Time </h3>
From the question, we are to determine the how long it would take the thermometer to hit the ground
From the given information,
The equation for the height as a function of time is
h(t) = -16t² + initial height
From the given information,
The thermometer falls from a weather balloon at a height of 7744 ft
∴ Initial height = 7744 ft
When the thermometer hits the ground, h(t) = 0
Thus, we get
0 = -16t² + 7744
16t² = 7744
t² = 7744/16
t² = 484
t = √484
t = 22 seconds
Hence, the time it will take the thermometer to hit the ground is 22 seconds
