Answer:

1. 2 subtracted from x² equals 5

2. The product of x and 5 subtracted from 3 is -10

Step-by-step explanation:

1.) x² - 2 = 5

2 subtracted from x² equals 5

2.) 3 - 5x = -10

The product of x and 5 subtracted from 3 is -10

How many solutions does the equation 3x + 6 equals -1 - 3 + 4x have?

wariber [46]

3x + 6 = -1 - 3 + 4x
Combine like terms on the right side.

3x + 6 = -4 + 4x
Add 4 to both sides.

3x + 10 = 4x
Subtract 3x from both sides.

10 = x

The equation has one solution (10).

If f(x)=ln(sin(2x)), f''(π/4) is equal to

Licemer1 [7]

Use the chain rule to compute the second derivative:

$f(x)=\ln(\sin(2x))$

The first derivative is

$f'(x)=(\ln(\sin(2x)))'=\dfrac{(\sin(2x))'}{\sin(2x)}=\dfrac{\cos(2x)(2x)'}{\sin(2x)}=\dfrac{2\cos(2x)}{\sin(2x)}$

$f'(x)=2\cot(2x)$

Then the second derivative is

$f''(x)=(2\cot(2x))'=-2\csc^2(2x)(2x)'$

$f''(x)=-4\csc^2(2x)$

Then plug in π/4 for x :

$f''\left(\dfrac\pi4\right)=-4\csc^2\left(\dfrac{2\pi}4\right)=-4$

What is the volume of the prism?

ozzi

Answer:

Step-by-step explanation:

When you find the volume of prisms, you're essentially taking the area of the base and multiply it by the length, in varied orientations.

In this case, I'd start by finding the area of the parallelogram facing us.

The formula for a parallelogram's area is the same as a rectangle's:

A = b x h

In this case, h = 3 cm and b = 8 cm.

A = 24 cm²

Now, you multiple the area by the length of the parallelogram, which is 8 cm.

V = 24 cm² x 8 cm

= 192 cm³

I hope this helps!
