Is the open sentence 3z=2z+5 true or false when z=5?<br><br> A. True<br> B. False

inna [77]

Hey there!

If z = 5

we replace "z" with "5"

So, let's test out the problem to see if it is true or false

Problem becomes: $3(5) = 2(5) + 5$

Let's work this out

$3(5) = 15$

Problem becomes: $15 = 2(5) + 5$

$2(5) = 10$

Problem becomes: $15 = 10 + 5$

$10 + 5 = 15$

So, therefore it looks like this statement/ sentence is $True$ !

Seven less than the quotient of a number, x, and twelve is five times the number. Which answer represents this situation??

erica [24]

Answer:

Option b is correct.

Step-by-step explanation:

From the given condition : Seven less than the quotient of a number, x, and twelve is five times the number.

Here, the number is x

The quotient of a number x and twelve is expressed as , $\frac{x}{12}$

Seven less than the quotient of a number, x, and twelve is expressed as, $\frac{x}{12}-7$

Five times the number mean, $5x$

Therefore, we have an equation in the form of <em>x</em> from the given condition as:

$\frac{x}{12}-7=5x$ .

Y = 3 sin2x, y = 0, 0 ≤ x ≤ π; about the x−axis

Dominik [7]

I assume you're revolving the region with those bounds about the x-axis, and supposed to find the volume.

Via the disk method,

$\displaystyle\pi\int_0^\pi(3\sin2x)^2\,\mathrm dx=9\pi\int_0^\pi\sin^22x\,\mathrm dx$

Recall the half-angle identity for sine:

$\sin^2t=\dfrac{1-\cos2t}2$
$\implies\displaystyle\frac{9\pi}2\int_0^\pi(1-\cos4x)\,\mathrm dx$
$=\displaystyle\frac{9\pi}2\left(x-\frac14\sin4x\right)\bigg|_{x=0}^{x=\pi}$
$=\dfrac{9\pi^2}2$
