Hello here is a solution :
f(x) = xsin(x)
f'(x) =( x)'sin(x) +x(sin(x))'
f'(x) = 1. sin(x)+x cos(x)

Which bar model could be used to show this situation?

9966 [12]

Answer:

C. The attached

Step-by-step explanation:

Our total is 44 dollars. This means that the largest bar, our whole, should be 44.

-> This rules out option D

Now, 4 sweatshirts are being bought. This means the 44 dollars should be broken up into 4 different parts since they all "cost the same amount of money."

-> This rules out options A, C, and D.

This leaves us with the correct option of option C.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Archie is stranded in a war zone in the land of the Xhosas. His only chance of survival is to reach Sudland, which lies 100 mile

LenaWriter [7]

Answer:

The chances of success for Archie is $P(S|D) = 35\%$

Step-by-step explanation:

From the question we are told that

The distance of Sudland from Xhosas is d = 100 miles

The probability of failure is $P(F) = 0.26$

The probability of choosing the desert route is $P(D) = \frac{1}{40} = 0.025$

The probability of reaching Sudland through the mountain is $P(S|M) =0.75$

Generally the probability of choosing the mountains route is

$P(M) = 1 - P(D)$

$P(M) = 1 - 0.025$

$P(M) = 0.975$

Generally the probability of success is mathematically represented as

$P(S) = 1- P(F)$

$P(S) = 1- 0.26$

$P(S) = 0.74$

Generally the probability of success in reaching Sudland is also mathematically represented as

$P(S) = P(S|M) * P(M) + P(S|D) * P(D)$

=> $P(S|D) = \frac{P(S) - P(S|M) * P(M)}{P(D)}$

substituting values

=> $P(S|D) = \frac{0.74 - 0.75 * 0.975}{0.025}$

=> $P(S|D) = 0.35$

=> $P(S|D) = 35\%$

I need help with the following question, whichever one is right will get brainliest!

Schach [20]

Given: m∠A + m∠B = 90° (Definition of Complementary Angles).

Given: m∠B = (5x + 8)°

A) m∠A = 180° + (5x + 8) is your answer choice:

Why it isn't the others:

B) m∠A = 90° - (5x + 8)

You are solving for complementary angles (90° in total when combined), so you subtract the measurement for B (5x + 8) to get A.

C) m∠A = 180° - 2(5x + 8)°

You double the complementary angle to solve for the supplementary. Essentially, just divide this answer by two to get the complementary angles.

D) m∠A = 82 - 5x

I was confused by this one, but essentially they just did one step of the isolating the variable, which was subtracting 8 from both sides. They did not finish isolating the variable however.
