Answer:

True

Step-by-step explanation:

It is the graph of 1/x shifted up 1 unit. You can check several points to see, if you like.

for x=1, y = 1/1 +1 = 2

for x=-1, y = 1/-1 +1 = 0

for x=1/2, y = 1/(1/2) +1 = 3

Put the equation in standard linear form.

$x'(t) + \dfrac{x(t)}{t + 5} = 5e^{5t}$

Find the integrating factor.

$\mu = \exp\left(\displaystyle \int \frac{dt}{t+5}\right) = e^{\ln|t+5|} = t+5$

Multiply both sides by $\mu$ .

$(t+5) x'(t) + x(t) = 5(t+5)e^{5t}$

Now the left side the derivative of a product,

$\bigg((t+5) x(t)\bigg)' = 5(t+5)e^{5t}$

Integrate both sides.

$(t+5) x(t) = \displaystyle 5 \int (t+5) e^{5t} \, dt$

On the right side, integrate by parts.

$(t+5) x(t) = \dfrac15 (5t+24) e^{5t} + C$

Solve for $x(t)$ .

$\boxed{x(t) = \dfrac{5t+24}{5t+25} e^{5t} + \dfrac C{t+5}}$

Given a right triangle with sides a = 3 , b = 4, and c = 5. Find the missing side c of another right triangle with a = 6 and b =

horsena [70]

c = 10

Step-by-step explanation:

We can find out the missing side of a right triangle by using the Pythagorean theorem.

The Pythagorean theorem is...

$a^2+b^2=c^2$

We can even double check the first problem by plugging in everything into the theorem and solving, everything will come out correct. We can plug in the numbers from the second problem into the theorem and find c, also please note that the hypotenuse of a triangle will always be c. It doesn't matter which you put in for a or b, but since the problem gives us which one is a and which one is b, I'll just be plugging it in like that.

$6^2+8^2=c^2$

$36+64=c^2$

$100=c^2$

A lot of people will stop here and think that the answer is 100, but you need to find the square root of 100, since c is squared. The square root of 100 is 10, so...

c = 10

Can someone give me the answer

Tasya [4]

Take the 4cm side and the 6cm side.

If you hook them together at one end, then there's no way they can reach the ends of the 11cm side. The farthest they can reach is 10cm.

That's what choice-B says.

What is the equation in point form of the line that passes through the point (2,6) and has a slope of 2

andriy [413]

point slope form

y-y1 = m(x-x1)

y-6 = 2(x-2)

from the answers shown, should the slope be 5?

then the answer would be

y-6 = 5(x-2)
