The error is line line 3. They did not probably square the numbers and only multiplied by two. Therefore line three should be 144+324=hypotenuse^2. Therefore line four should be 468 = hypotenuse^2. So the hypotenuse will be equal 6 square root of 13.

Line 3 is where the error begins. 12^2 is not equal to 24, it is equal to 144. Same for 18^2.

Answer:
468 = hypotenuse^2
Hypotenuse= square root of 468

1. A water wheel rung’s height as a function of time can be modeled by the equation:

Nimfa-mama [501]

Answer:

-1

Step-by-step explanation:

1. A water wheel rung’s height as a function of time can be modeled by the equation:

h - 8 = -9 sin6t

(b) Determine the maximum height above the water for a rung.

Given the rung's height modeled by the equation;

h - 8 = -9 sin6t

h(t) = -9sin6t + 8

At maximum height, the velocity of the rung is zero;

dh/dt = 0

dh/dt = -54cos6t

-54cos6t = 0

cos6t = 0/-54

cos6t = 0

6t = cos^-1(0)

6t = 90

t = 90/6

t= 15

Substitute t = 15 into the expression to get the maximum height;

Recall:

h(t) = -9sin6t + 8

h(15) = -9sin6(15) + 8

h(15) = -9sin90 + 8

h(15) = -9(1)+8

h(15) = -9+8

h(15) = -1

hence the maximum height above the water is -1

The value of a rare baseball card A appreciated by 20 percent over a five year period; over the next five years, the value plumm

lbvjy [14]

<h2>Answer:</h2>

Percent value of A with respect to Percent value of B is,

$30\%$

<h2>Step-by-step explanation:</h2>

In the question,

Let us say the value of the Baseball card A and B initially is = 100x

So, for Baseball card A in first 5 years percent increase = 20%

So,

Value after 5 years = 100x + 20% of 100x = 120x

After 5 more years,

Percent decrease = 50%

So,

Value at the end of 10 years = 120x - 50% of 120x = 60x

Now,

For Baseball card B, Percent increase in 10 years = 100%

So,

Value of card B = 100x + 100% of 100x = 200x

So,

Percent value of A with respect to Percent value of B is,

$\frac{60x}{200x}\times 100=30\%$
