The mean sustained wind velocity, v, can be determined by the equation v = 6.3 StartRoot 1013 minus p EndRoot, where p is the air pressure, in millibars, at the center of the hurricane. What is the approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second?

Answers

Answer 1

Answer:

Answer:

909.8 millibars.

Step-by-step explanation:

The mean sustained velocity, v be determined by the equation:

$v=6.3√(1013-p)$ , where p is the air pressure, in millibars, at the center of the hurricane.

Given that: v=64 meters per second, we are to find the value of p.

$64=6.3√(1013-p)\n$Square both sides to eliminate the square root sign\n(64)^2=(6.3√(1013-p))^2\n4096=39.69(1013-p)\n$Divide both sides by 39.69$\n(4096)/(39.69)=1013-p\n $Therefore:$\np=1013-(4096)/(39.69)\n\np=909.8$ millibars$

The approximate air pressure at the center of a hurricane when the mean sustained wind velocity is 64 meters per second is 909.8 millibars.

If y=2x-3 were changed to y=2x+5 , how would the graph of new function compare with the original?

Answers

The new graph would have the same slope (2) as the original one,
but its y-intercept would be [ 5 - (-3) ] = 8 higher.

The new straight line would be parallel to the original straight line,
and they would be 8 units apart everywhere.

Answer: it would be shifted up

How can x + 8 = -x + 7 be set up as a system of equations? y = x + 8
y = -x + 7
y = x + 8
y = -3x + 7
y = x + 5
y = -2x + 11
y = 8
y = -3x + 7

Answers

The first answer choice is correct

separate x + 8 and -x + 7 and set them both to equal y

y = x + 8 ; y = -x + 7

Answer:

The answer is y = x + 8

y = -x + 7

Operation and simplify the answer fully. (9x)/(5)*(5)/(4x^(2)) Submit Answer

Answers

Answer:

To simplify the expression (9x/5) * (5/4x^2), we can cancel out common factors.

= (9x * 5) / (5 * 4x^2)

= (45x) / (20x^2)

= (9/4) * (x / x^2)

= (9/4) * (1 / x)

Therefore, the simplified expression is (9/4) * (1 / x) or (9 / 4x).

Step-by-step explanation:

Final answer:

To solve the given expression $(9x)/(5)*(5)/(4x^(2)$ , we multiply the numerators together and the denominators together. Simplifying further by canceling out common factors and dividing by x, the final simplified expression is 9/(4x).
