A weather balloon is released and rises vertically such that its distance s (t) above the ground during the first 10 sec of flight is given by s(t)-6+2t+t2, where s(t) is in feet and t is in (a) Find the velocity at t- 4 seconds. (Worth 5 points) sec/Pt Answer (b) Find the instant the balloon is 50 feet above the ground.
Step-by-step explanation:
A weather balloon is released and rises vertically such that its distance s (t) above the ground during the first 10 sec of flight is given by :
[tex]s(t)=6+2t+t^2[/tex] ...(1)
(a) We need to find velocity at t = 4 seconds
Differentiate equation (1) wrt t.
[tex]v=\dfrac{ds}{dt}\\\\v=\dfrac{d(6+2t+t^2)}{dt}\\\\v=2+2t[/tex]
At t = 4 seconds,
[tex]v=2+2(4)\\\\=10\ ft/s[/tex]
At t = 4 seconds, the velocity is 10 ft/s.
(b) When the balloon is 50 feet above the ground,
[tex]6+2t+t^2=50[/tex]
We need to find t.
[tex]6+2t+t^2=50\\\\t^2+2t-50+6=0\\\\t^2+2t-44=0[/tex]
It is a quadratic equation,
t = 5.708 and t = -7.708
Neglecting negative time, the instant time is 5.708 seconds.

A cylindrical soup can has a radius of 8.4 cm and a height of 13.2 cm. What is the volume of the soup can to the nearest tenth of a cubic centimeter?
A= 110.9 cm3
B= 348.3 cm3
C= 673.8 cm3
D= 2926.1 cm3
Answer:
Option D: 2926.1 cm³
Step-by-step explanation:
Dimensions of the cylidrincal soup can are given as;
Radius; r = 8.4 cm
height; h = 13.2 cm
Formula for area of cylinder is;
A = πr²h
Plugging in the relevant values gives;
A = π × 8.4² × 13.2
A = 2926.05 cm³
Approximating to the nearest tenth gives;
A = 2926.1 cm³
If a+b/a-b=5/3, what are the following ratios? 2a-4b/a-2b
Answer:
Hope this may helps you
The value of ratios (2a - 4b) / (a - 2b) is,
⇒ 2
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
The value is,
⇒ (a + b )/ (a-b) = 5/3
Now, We get;
⇒ a + b = 5
⇒ a - b = 3
Hence, By solving above equation,
a = 4
b = 1
Thus, The value of ratios (2a - 4b) / (a - 2b) is,
⇒ (2a - 4b) / (a - 2b)
⇒ (2 × 4 - 4 × 1) / (4 - 2 × 1)
⇒ (8 - 4) / (4 - 2)
⇒ 4 / 2
⇒ 2
Thus, The value of ratios (2a - 4b) / (a - 2b) is,
⇒ 2

Which of the following numbers can be expressed as decimals that terminate? 5 over 2, 4 over 5, 2 over 7, 4 over 3 5 over 2 and 2 over 7 4 over 5 and 4 over 3 5 over 2 and 4 over 5 2 over 7 and 4 over 3 my friend needs help
Answer:
I hope this helps!!
Step-by-step explanation:
We have given that : numbers - 9 over 7, 5 over 3, 3 over 2, 6 over 4
To find : which are terminating decimal
Terminating decimals are those whose figures to the right of some place are zero or have an end.
Solution : we check one by one,
1) 9 over 7 = 9/7 = 1.285714285714285714.... -Non terminating
2) 5 over 3 = 5/3 = 1.666666666666666...... -Non terminating
3) 3 over 2 = 3/2 = 1.5 - Terminating
4) 6 over 4 = 6/4= 3/2 = 1.5 - Terminating

Write a polynomial expression that represents the total area of a square with a side length of (3x - 4).
g(x) = x^2 + 55
What is the minimum value of the given function?
Answer:
Step-by-step explanation:
55.
The solution is, the function doesn't have a minimum value.
What is derivative?A derivative is described as either the rate of change of a function, or the slope of the tangent line at a particular point on a function.
here, we have,
given that,
the function is,
g(x) = x^2 + 55
now, we have to find the min. value of the function.
so, we have,
g(x) = x^2 + 55
the 1st order derivative is,
g'(x)= 2x
now, we have, critical point, at g'(x)= 0
i.e. at 2x = 0
or, x = 0
so, min. value is at x= 0 of g''(x),
i.e. g''(x) = 2
so, it doesn't have any minimum value.
Hence, The solution is, the function doesn't have a minimum value.
