Answer:
they both = 100
Step-by-step explanation:
Answer:
Problem 20)
Problem 21)
A)
The velocity function is:
The acceleration function is:
B)
Step-by-step explanation:
Problem 20)
We want to differentiate the equation:
We can take the natural log of both sides. This yields:
Since ln(aᵇ) = bln(a):
Take the derivative of both sides with respect to <em>x: </em>
<em /><em />
Implicitly differentiate the left and use the product rule on the right. Therefore:
Simplify:
Simplify and multiply both sides by <em>y: </em>
<em /><em />
Since <em>y</em> = (cos x)ˣ:
Problem 21)
We are given the position function of a particle:
A)
Recall that the velocity function is the derivative of the position function. Hence:
Differentiate:
The acceleration function is the derivative of the velocity function. Hence:
Differentiate:
B)
The position at <em>t</em> = 0 will be:
The velocity at <em>t</em> = 0 will be:
And the acceleration at <em>t</em> = 0 will be:
Answer:
The answer is 173.45
Step-by-step explanation:
132.20 + 74.50 - 52 + 18.75 =173.45
I hope this helps
Option(4) is the answer because
In triangle ABC and triangle EDC
Angle ABC=angle CDE=70
And,
Angle BCA= angle DCE. ( vertically opposite angles)
=> triangle ABC is similar to triangle EDC. ( A.A congruence rule)
=> angle A= angle E. (Corresponding parts of similar triangles) or (CPST)
Hope this helps ..!!!
