Is (x +1) a factor of f(x) = x^3 + x^2 −4x − 4? Select the appropriate response:
Yes
or
No

Answers

Answer:

Yes

Step-by-step explanation:

f(x) = x^3 + x^2 −4x − 4

Factor by grouping taking x^2 out of the first group and -4 out of the second

0 = x^3 + x^2 −4x − 4

x^2(x+1) -4(x+1)

Factor out (x+1)

0=(x+1)(x^2-4)

Now we have the difference of squares

0=(x+1) (x-2)(x+2)

x+1 is a factor

Answer:

Yes

Step-by-step explanation:

( x^3 + x^2) (-4x - 4)

x^2 ( x+1) -4 (x+1)

(x^2 - 4) (x+1)

(x-2) (x+2) (x+1)

N a water treatment plant, water passes through a cone-shaped filter with a height of 4 m and a diameter of 9 m. The water flows from the filter into a cylinder below it. One full cone-shaped filter fills one-fifth of the cylinder.What are the dimensions of the cylinder? Use 3.14 to approximate pi.
A. h = 3 m; r = 3 m
B.h = 4.23 m; r = 5 m
C.h = 15 m; r = 6 m
D.h = 33.75 m; r = 2 m

Answers

Given:
Cone-shaped filter: height = 4m ; diameter = 9m
cylinder: one full cone-shape filter fills 1/5 of the cylinder

volume of the cone = π r² h/3 = 3.14 * (4.5m)² * 4m/3
V = 3.14 * 20.25m² * 1.33m
V = 84.57 m³

84.57 m³ ÷ 1/5 = 84.57 m³ * 5 = 422.85 m³ volume of the cylinder

Volume of cylinder = π r² h

Choice A: V = 3.14 * (3m)² * 3m = 3.14 * 9m² * 3m = 84.78 m³
Choice B: V = 3.14 * (5m)² * 4.23m = 3.14 * 25m² * 4.23m = 332.10 m³
Choice C: V = 3.14 * (6m)² * 15m = 3.14 * 36m² * 15m = 1695.60 m³
Choice D: V = 3.14 * (2m)² * 33.75 m = 3.14 * 4m² * 33.75m = 423.90 m³

The closest answer is Choice D. height = 33.75 m ; radius = 2 m

The bakery bought four bags of flour containing 3.5 kg each 475 g of flour are needed to make a batch of muffins and 0.65 kg is needed to make a loaf of bread if 4 batches of muffins and five loaves of bread are baked how much flour will be left give your answer in kilograms

Answers

First we have to find total mass of flour.
4*3.5kg=14kg
Now we are calculating how much flour we used for muffins
475g=0.475kg
0.475kg*4muffins=1.9kg
and now how much flour we used for bread
0.65kg*5bread=3.25kg
Finally we can subtract 1.9 and 3.25 from 14kg
14kg-1.9kg-3.25=8.85kg - its the answer

The left out amount of floor is $\boxed{\bf8.85\,\,{\text{kilogram}}}$ .

Further explanation:

The weight of one bag of flour is 3.5 kg.

The bakery bought 4 bags of flour.

Therefore, the total weight of 4 bags is calculated as follows:

$4*\left({3.5\,\,{\text{kg}}}\right)=14\,\,{\text{kg}}$

The weight of flour needed for a batch of muffins is 0.475 kg.

Therefore, the weight of flour needed for 4 batches of muffins is calculated as follows:

$4*\left({0.475\,\,{\text{kg}}} \right)=1.9\,\,{\text{kg}}$

The weight of flour needed for a loaf of bread is 0.65 kg.

Therefore, the weight of flour needed for 5 loaves of bread is calculated as follows:

$5*\left( {0.65\,\,{\text{kg}}} \right)=3.25\,\,{\text{kg}}$

So, the total weight of floor used in the process of making muffins and loaves of bread is calculated as follows:

$3.25\,\,{\text{kg+}}1.9\,\,{\text{kg}}=5.15\,\,{\text{kg}}$

Now, the weight of floor that is left out in the bag is calculated as follows:

$14\,\,{\text{kg}}-5.15\,\,{\text{kg}}=8.85\,\,{\text{kg}}$

Thus, the left out amount of floor is $\boxed{\bf8.85\,\,{\text{kilogram}}}$ .

A road crew must repave a road that is 3/5 miles long. They can repave 1/15 miles each hour. How long will it take the crew to repave the road?

Answers

The Total number of hours required to repave the whole road is 36.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

The Total length of the road that needs to be repaved = 3/5 miles

The Total length of the road which is repaved by the road crew per hour = 3/5 miles

The Total number of hours required to repave the whole road

= (Length of the road to be repaved)/(Length of the road repaved by the crew per hour)

= 3/4 divided by 1/48

= 3/4*48/1= 144/4

= 36

Hence, The Total number of hours required to repave the whole road is 36.
