Mathematics

Answer:

It's not very high

Step-by-step explanation:

The angle that the string and the ground maje, is acute, because it's smaller than a right angle. So, since it is an acute angle, it's not very high. It is about 30cm high.

the derivative of the function f is given by f'(x)=x^2cos(x^2). How many points of inflection does the graph of f have on the op
Vsevolod [243]
The point of inflection is calculated by equating the second derivative to zero and determining x from there.

f"(x) = -x²2xsinx² + cosx²(2x) = 0

2xcosx² - 2x³sinx² = 0
2x (cosx² - xsinx²) = 0

2x = 0   ⇒  x = 0
cosx² - xsinx² = 0   ⇒ x = 3.82 (if you use shift+solve in your scientific calculator)

Thus, the function only has 1 point of inflection and it is at x = 0.

Junior has 4 skittles in a bag, one is red, one is blue, one is green, and one is yellow. Junior takes a skittle out and eats it
forsale [732]

Answer:

The tree diagram is shown below.

Step-by-step explanation:

The color of the four skittles Junior had in his bag are:

S = {red (R), blue (B), green (G) and yellow (Y)}

It is provided that Junior takes a skittle out and eats it and then takes another skittle from the bag.

So, Junior has four options for the first draw, i.e. {R, B, G and Y}.

Then three options for the second draw. But the second draw is dependent on the first draw.

  • If Junior ate the red skittle first, then the second skittle could be any of the three, (B, G and Y).
  • If Junior ate the blue skittle first, then the second skittle could be any of the three, (R, G and Y).
  • If Junior ate the green skittle first, then the second skittle could be any of the three, (R, B and Y).
  • If Junior ate the yellow skittle first, then the second skittle could be any of the three, (R, B and G).

Consider the tree diagram below to better understand the information above.

Aleena has a savings account that gives 5% annual interest. She deposits $200 that she received on her birthday. Write an equati
ANTONII [103]

Answer:the equation is 200 + 10x

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount deposited into the account.

R represents interest rate on the principal

T represents time in years

I = interest after t years

From the information given

T = x years

P = $200

R = 5%

Therefore

I = (200 × 5 × x)/100

I = 1000x/100

I = 10x

Therefore, the equation representing the total amount of money that would be in the account after x years would be

200 + 10x
