Answer:

Option A is correct.

Step-by-step explanation:

The polynomial with factors with zeros at 0,-3 and 4 means

x=0 and x =-3 and x=4

this can be written as:

x=0, x+3 =0 and x-4=0

x(x+3)(x-4) =0

f(x) = x(x+3)(x-4)

So, Option A is correct.

A. 2 meters to centimeters

1 m = 100 cm

$2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2$

B)108 centimeters to meters

100 cm =1 m

$1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m$

C)2.49 meters to centimeters

1 m = 100 cm

$2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm$

D)50 centimeters to meters

100 cm = 1m

$1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m$

E)6.3 meters to centimeters

1 m = 100 cm

$6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630 cm$

F)7 centimeters to meters

100 cm = 1 m

$1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m$

a)4 meters to millimeters

1 m = 1000 mm

$4 m = 4000 = 4 \times 10^3 mm$

b)1.7 meters to millimeters

1 m = 1000 mm

$1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm$

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 6 cubic feet per minute. The dia

Alla [95]

Answer:

$0.2122\text{ ft per min}$

Step-by-step explanation:

Let r be the radius ( in feet ) of the cone,

So, the diameter of the cone = 2 × radius = 2r feet,

∵ The diameter of the base of the cone is three times the height,

If h represents the height of the cone,

⇒ 2r = 3 × h,

⇒ $r=\frac{3h}{2}$ feet,

∵ Volume of a cone,

$V=\frac{1}{3}\pi R^2 H$

Where,

R = radius, H = height,

Thus, the volume of the given cone is,

$V=\frac{1}{3}\pi r^2 h$

$=\frac{1}{3}\pi (\frac{3h}{2})^2 h$

$=\frac{3}{4}\pi h^3$

Differentiating with respect to t ( time )

$\frac{dV}{dt}=\frac{9}{4}\pi h^2\frac{dh}{dt}$

We have,

$\frac{dV}{dt}=6\text{ cubic ft per min},h=2\text{ feet}$

$6=\frac{9}{4}\pi (2)^2 \frac{dh}{dt}$

$6=9\pi \frac{dh}{dt}$

$\implies \frac{dh}{dt}=\frac{6}{9\pi }\approx 0.2122\text{ ft per min}$

Can you please help me with solving this math problem. 1/4 (x+2)=5/6

Verdich [7]

So firstly, multiply both sides by 4 (the reciprocal of 1/4): $x+2=\frac{20}{6}=3\frac{2}{6}$

Next, subtract both sides by 2 and your answer will be: $x=1\frac{2}{6}$
