The correct option is Option 4: $2a^2b^3 + 10ab^4$

Step-by-step explanation:

Given

Length of box = l = ab

Width of box = w = a+5b

Height of box = h = 2b^2

The volume of a box is given by:

$V = Length*Width*Height\\V = l*w*h$

Putting the values

$V = (ab)(a+5b)(2b^2)\\ = (ab)(2b^2)(a+5b)\\=(2ab^3)(a+5b)\\Distributive property\\=(2ab^3*a) + (2ab^3*5b)\\=2a^2b^3 + 10ab^4$

Hence,

The correct option is Option 4: $2a^2b^3 + 10ab^4$

A guy wire anchors down a wind turbine. The anchor for the wire is 93 m away from the base of the turbine, and it connects to th

vredina [299]

Answer: $68.49^{\circ}$

Step-by-step explanation:

Given: The anchor for the wire is 93 m away from the base of the turbine.

It connects to the turbine 236 m above the ground.

Let x be the angle of elevation for the guy wire

By trigonometry,

$\tan x=\frac{\text{side opposite to x}}{\text{side adjacent to x}}\\\Rightarrow\ \tan x=\frac{236}{93}\\\Rightarrow\ x=\tan^{-1}(\frac{236}{93})\\\Rightarrow\ x=\tan^{-1}(2.5376)\\\Rightarrow\ x=1.195\ radians \\\\\Rightarrow\ 1.195\times\frac{180^{\circ}}{\pi}=68.49219\approx68.49^{\circ}$

QUICK HELP! Which graph represents the product of a complex number, z, and the negative real number -1/3 ?

jenyasd209 [6]

Answer:

Step-by-step explanation:

The minus sign (of the multiplier -1/3) changes the direction of z by 180°. The magnitude of the multiplier 1/3 reduces the magnitude of the product to 1/3 that of z. The graph that has these characteristics is graph C.
