Answer:

$y=cos(x + \pi)$

Step-by-step explanation:

Remember that the cosine function has a period of 2π.

Now, the parental function is $y=cosx$ , which has y-intercept at y = 1, and x-intercept at π/2.

Notice that the function showed in the graph attached has y-intercept at y = -1 and x-intercept at π/2. This indicates that the function has been moved leftwards π units.

Therefore, the function that belongs to this graph is

$y=cos(x + \pi)$

A man travels by a car from Town A to Town B, a total distance of x km/h. He finds that the time for the journey would be shorte

Vesnalui [34]

The question is incomplete. The complete question is :

A man travels by a car from town A to town B, a total distance of 100 km at an average speed of x km/h. he finds that the time for the journey would be shorter by 25 minutes if he increases his average speed by 12km/h. Find x ?

Solution :

It is given the that the distance between town A and B is = 100 km

His initial average speed is = x km/h

His increased average speed is = 12 km/h

Time is shortened by = 25 minutes

So according to the question,

$\frac{x \ km/h}{100\ km}-\frac{12 \ km/h}{100 \ km} = 25$

$\frac{x-12}{100}=25$

x-12 = 2500

x = 2512

The area of the continent of Susan America is about 6,888,000 square miles. Write 6,888,000 in expanded form using multiplicatio

Ilia_Sergeevich [38]

The area of the continent of Susan America which is 6,888,000 square miles can be written as 688* $10^{3}$ .

Given that the area of the continent of Susan America be 6888000 square miles.

We are required to express the area in the multiplication form by using the place values.

Area is basically quantity that expresses the extent of a region on the plane or on a curved surface.

Multiplication is basically finding the number which is product of two numbers.

6888000 can be written as 6888* $10^{3}$ which can be found out by the cube of 10 and multiply that by 6888.

Hence the area of the continent of Susan America which is 6,888,000 square miles can be written as 6888* $10^{3}$ .

Solve the equation. 7x2 + 5 - x = 6x2 + 10 X =

GarryVolchara [31]

Answer:

x = -5

Step-by-step explanation:

7 × 2 + 5 - x = 6 × 2 + 10

Multiply.

14 + 5 - x = 12 + 10.

Combine like terms.

19 - x = 24

Isolate x (I'm going to add x and subtract 24 from both sides to avoid changing signs)

-5 = x

Final answer

x = -5

Factor x3 + 2x2 + x completely. a. (x+1)^2 b. x(x+1)^2 c. x(x+1)^2

enot [183]

Option B

ANSWER:

The factors of $x^{3}+2 x^{2}+x$ is $x(x+1)^{2}$

SOLUTION:

Given, cubic expression is $x^{3}+2 x^{2}+x$

Now, we have to find the factors of above equation.

To factorize the given equation, follow the below steps:

$\mathrm{x}^{3}+2 \mathrm{x}^{2}+\mathrm{x}$

Since x is common in every term of expression, we can take it as common

$x\left(x^{2}+2 x+1\right)$

“2x” can be rewritten as “x + x”, the above equation becomes,

$x\left(x^{2}+x+x+1\right)$

Taking the common terms out of bracket. we get

x(x (x + 1) + 1 (x + 1))

Taking (x + 1) as common., we get

x ((x + 1)(x + 1))

$x(x+1)^{2}$

Hence, the second option b is correct.
