Answer:

f(x) = 15

Step-by-step explanation:

"If f(x)= 5x + 40, what is f(x) when x = -5?"

Substitute x for -5:

f(x) = 5x + 40

f(x) = 5(-5) + 40

f(x) = -25 + 40

f(x) = 15

Can somebody explain this to me when 2du = 16xdx ???

tamaranim1 [39]

When you set $u=4x^2+4$ , you end up with the differentials $\mathrm du=8x\,\mathrm dx$ . Multiplying both sides by 2 gives $2\,\mathrm du=16x\,\mathrm dx$ .

Then the integral is

$\displaystyle\int_0^1\frac{16x}{(4x^2+4)^2}\,\mathrm dx=\int_4^8\frac2{u^2}\,\mathrm du=-\frac2u\bigg|_{u=4}^{u=8}=-2\left(\frac18-\frac14\right)=\frac14$

In order for the parallelogram to be a rhombus x = ?

Zina [86]

Answer: x= 207.8873386

Step-by-step explanation:

expecting both 2x-15 and 3x are angles in radiant, let's draw a rhombus ABCD

∠ABC = 2x-15

∠ BCD = 3x

∠ABC + < BCD= π ( 180° in radiant)

2x - 15 + 3x = π

5x - 15 = π

x - 3 = 1/5π

= 3.628318531 = 207.8873386

2x−15°+3x=180

5x-15°=180

5x=195°

x=39°
