PEMDAS
[Calculus] analyze speed from position. Show steps, please!
Answers
Answer:
B
Step-by-step explanation:
We are given that the position of a particle is modeled by the function:
[tex]s(t)=2t^3-24t^2+90t+7[/tex]
And we want to find the times for which the speed of our particle is increasing.
In other words, we want to find the times for which our acceleration is positive (a(t)>0).
So first, we will find our acceleration function. We can differentiate twice.
By taking the derivative of both sides with respect to t, we acquire:
[tex]\displaystyle s^\prime(t)=v(t)=\frac{d}{dt}\big[2t^3-24t^2+90t+7\big][/tex]
Differentiate:
[tex]v(t)=6t^2-48t+90[/tex]
This is our velocity function. We can differentiate once more to acquire the acceleration function. Therefore:
[tex]\displaystyle v^\prime(t)=a(t)=\frac{d}{dt}\big[6t^2-48t+90\big][/tex]
Differentiate:
[tex]a(t)=12t-48[/tex]
If our speed is increasing, our acceleration must be positive. So:
[tex]a(t)>0[/tex]
By substitution:
[tex]12t-48>0[/tex]
Now, we can solve for t:
[tex]12t>48\Rightarrow t>4[/tex]
Therefore, the only interval for which the speed of the particle is increasing (i.e. the acceleration is positive) is for all times t>4.
So, our answer is B.

The multiplicative rate of change that should be in Hal’s function = 49/50=0.98
=9.8×10⁻¹
Explanation
The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.
In this case the first term = 10000
The second term = 98% × 10000 = 9800.
The common ratio = 9800/10000=49/50
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.
The equation of the exponential rate would be;
10,000ₓ0.98ⁿ.
where n is the number years.

Answer:
1). Option (A)
2). Option (A)
Step-by-step explanation:
1). A worker bee has the mass = 0.00011 kg
In scientific notation we can convert the mass of bee as,
0.00011 =
=
Since 1.1 ≈ 1,
Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg
Option (A) is the answer.
2). An African elephant has a mass = 8139 kg
In scientific notation,
8139 = 8.139 × 10³
Since, 8.139 ≈ 8
Therefore, 8139 kg = 8.139 × 10³ kg
Option (A) is the answer.

-6.8 is the answer.
Step-by-step explanation:
It seems as if those ticks each represent 0.1. So go 0.3 down from -6.5!
Hope this helped! Have a great day!
Each line is .1 so going down three times from -6.5 would give you -6.8
A rectangle measures 7.08 cm by 3.2 cm.
Work out the area of the rectangle.
Answers
Answer:
22.67 cm^2
Step-by-step explanation:
The computation of the area of the rectangle is shown below:
As we know that
Area of the rectangle = Length × breadth
Here we assume the length be 7.08 cm
Or breadth be 3.2 cm
Or if we assume them inverse like length be 7.08 cm and breadth be 3.2 cm
SO the area of the rectangle is
= 7.08 cm × 3.2 cm
= 22.67 cm^2
In the both cases the answer would be the same

Ted has a part-time job.
He is paid £7.90 per hour.
Last week he worked for 15/2 hours.
Work out Ted's total pay for last week.
Answers
Answer:
The answer is 122.45
Step-by-step explanation:
So basically we know that he worked 15 and 1/2 hours
He gets paid £7.90 for every hour he works
7.90 × 15 = 118.5
Then you do half of £7.90 which is £3.95 because he worked 1/2 hours half of 60 minutes is 30 minutes that why you half £7.90.
You add 118.5 + 3.95 = £122.45
and that your answer

A small artichoke contains about 9 milligrams of vitamin C. It also contains about 15% of the recommended amount of vitamin C an average adult should get each day. About how many artichokes would an average adult have to eat in a day to get the necessary amount of vitamin C.
Answers
Answer:
7 Artichokes
Step-by-step explanation:
To figure this out, we need to find out how much Vitamin C an average adult needs. We set up a proportion.
[tex]\frac{9}{15} = \frac{x}{100}[/tex]
[tex]15x=900[/tex]
[tex]x=60[/tex]
Now, since each artichoke is worth 9 milligrams, we divide 60 by 9.
[tex]60/9=6.66666...[/tex]
So, to get the necessary amount of Vitamin C, we round up to 7.

A painter leans an 18 foot ladder against the house so that the base of the ladder is 4 feet away from the wall. Approximately how far up the side of the house does the ladder reach?
Answers
Answer: 17.5ft
Step-by-step explanation:
Use Pythagorean theorem
A^2 + B^2 = c^2 where c is the hypotenuse
The ladder leaning against the wall is the hypotenuse.
4^2 + b^2 = 18^2
16 + b^2 = 324
324-16 = b^2
308 = b^2
B = 17.5ft
Solve using Substitution Method. 5x-y=-6 10x+3y=-32
Answers
Answer:
x= -2
y= -4
Step-by-step explanation:
1) solve for y in 5x-y= -6
which would be y= 5x+6
2) substitute that in for y in the second equation
which would be 10x+3(5x+6)= -32
3) solve that new equation
which would be x= -2
4) plug x= -2 into either equation (the shorter equation is the one i chose)
which would be 5(-2) - y = -6
5) solve that new equation
which would be y= -4
