A washer and dryer costs $793 combined. The washer costs $57 less than the dryer. How much does the dryer cost?

1 answer:

4 0

The dryer costs $368

w - washer
d - dryer

w + d = 793
( d - 57) = w

( d - 57) + d = 793
2d - 57 = 793
2d = 736
d = 368

Find the solution of the differential equation that satisfies the given initial condition. y' tan x = 3a + y, y(π/3) = 3a, 0 &lt

Paladinen [302]

Answer:

$y(x)=4a\sqrt{3}* sin(x)-3a$

Step-by-step explanation:

We have a separable equation, first let's rewrite the equation as:

$\frac{dy(x)}{dx} =\frac{3a+y}{tan(x)}$

But:

$\frac{1}{tan(x)} =cot(x)$

So:

$\frac{dy(x)}{dx} =cot(x)*(3a+y)$

Multiplying both sides by dx and dividing both sides by 3a+y:

$\frac{dy}{3a+y} =cot(x)dx$

Integrating both sides:

$\int\ \frac{dy}{3a+y} =\int\cot(x) \, dx$

Evaluating the integrals:

$log(3a+y)=log(sin(x))+C_1$

Where C1 is an arbitrary constant.

Solving for y:

$y(x)=-3a+e^{C_1} sin(x)$

$e^{C_1} =constant$

So:

$y(x)=C_1*sin(x)-3a$

Finally, let's evaluate the initial condition in order to find C1:

$y(\frac{\pi}{3} )=3a=C_1*sin(\frac{\pi}{3})-3a\\ 3a=C_1*\frac{\sqrt{3} }{2} -3a$

Solving for C1:

$C_1=4a\sqrt{3}$

Therefore:

$y(x)=4a\sqrt{3}* sin(x)-3a$

Answer:

The answer is x = 12.

Step-by-step explanation:

We can solve this using proportion.

$\frac{x}{2} = \frac{66}{12 } \\ \\ \frac{132}{12} = \frac{12x}{12} \\ \\ x = 11$

A screening test for a newly discovered disease was evaluated in order to determine how well the test performs. Investigators ad

saw5 [17]

Answer:

B. 71.43%

Step-by-step explanation:

The sensitivity is the probability that a test will indicate 'disease' among those with the disease, that is, the test has a positive results:

In this problem, we have that:

150 people with the disease tested positive and 60 tested negative. So the sensitivity is:

$S = 100*\frac{150}{210} = 71.43$

The correct answer is:

B. 71.43%
