I'll do the first three questions to get you started.

==========================================================

Question 1

x = horizontal component of the triangle

cos(angle) = adjacent/hypotenuse

cos(theta) = horizontal/hypotenuse

cos(40) = x/30

x = 30*cos(40)

x = 22.98133329 approximately

This is the horizontal force applies to the suitcase.

Work = force*displacement

Work = 22.98133329*120

Work = 2,757.7599948

Work = 2,758

<h3>Answer: 2,758 Nm (choice B)</h3>

==========================================================

Question 2

Add the drone's relative air velocity and the wind velocity vectors.

v+w = (13i + 3j) + (-7i - 2j)

v+w = (13i-7i) + (3j-2j)

v+w = 6i + j

<h3>Answer: 6i + j (choice B)</h3>

==========================================================

Question 3

Check out the diagram below. Focus on the smaller triangle. Notice the placement of angle theta.

sin(theta) = opposite/hypotenuse

sin(40) = x/200

x = 200*sin(40)

x = 128.557521937308

x = 128.558

<h3>Answer: 128.558 pounds (choice A)</h3>

Please identify the error<br> 8 - (-2) = -8 +2 = -6

Vika [28.1K]

False bc

8+2=-8+2
8=-8
But if it was solve:
8-(-2) the answer is:
8+2=10

Olegator [25]

Answer:

a = 8

b = -8

Step-by-step explanation:

You have the following function:

$f(x)\\\\=at+b;\ \ t$

A function is differentiable at a point c, if the derivative of the function in such a point exists. That is, f'(c) exists.

In this case, you need that the function is differentiable for t=2, then, you have:

$f'(t)=a;\ \ \ \ t$

If the derivative exists for t=2, it is necessary that the previous derivatives are equal:

$f'(2)=a=4(2)\\\\a=8$

Furthermore it is necessary that for t=2, both parts of the function are equal:

$8(2)+b=2(2)^2-1\\\\16+b=8-1\\\\b=-8$

Then, a = 8, b = -8

BRAINLIEST AND 39 POINTS

Veronika [31]

You have 10 numbers to choose from, and you're choosing 4 from that pool. Order of the numbers matters, because having 1234 as a PIN is not the same having it be 1324, so we're counting the number of permutations of 10 digits taken 4 at a time. So there are

$4!\dbinom{10}4=4!C(10,4)=4!C^{10}_4=\dfrac{10!}{(10-4)!}=5040$

possible PINs that can be made.
