Find the distance travelled by Rubina if she takes 4 rounds of rectangular park whose length and breadth is 45m and 30m

please give me a valid answer with a step by step explanation and i will mark you as brainliest

Length (l) = 45 mBreadth (b) = 30 mWe know, perimeter of a rectangle = 2(length + breadth)Therefore, perimeter of the rectangle = 2(I + b) = 2(45 + 30) m = 2 × 75 m = 150 mSo, the distance travelled by Rubina = 4 × 150 m= 600 m

Answer:

*The **distance **travelled** **by **Rubina **is **6**0**0** **m.*

Hope you could get an idea from here.

if p(q) = q^2 4q- 12 then what is p(-1)

the solution:

(1): "q2" was replaced by "q^2".

Step by step solution :

STEP

:

Trying to factor by splitting the middle term

1.1 Factoring q2-4q-12

The first term is, q2 its coefficient is 1 .

The middle term is, -4q its coefficient is -4 .

The last term, "the constant", is -12

Step-1 : Multiply the coefficient of the first term by the constant 1 • -12 = -12

Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -4 .

-12 + 1 = -11

-6 + 2 = -4 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 2

q2 - 6q + 2q - 12

Step-4 : Add up the first 2 terms, pulling out like factors :

q • (q-6)

Add up the last 2 terms, pulling out common factors :

2 • (q-6)

Step-5 : Add up the four terms of step 4 :

(q+2) • (q-6)

Which is the desired factorization

Equation at the end of step

:

(q + 2) • (q - 6) = 0

STEP

:

Theory - Roots of a product

2.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

2.2 Solve : q+2 = 0

Subtract 2 from both sides of the equation :

q = -2

Solving a Single Variable Equation:

2.3 Solve : q-6 = 0

Add 6 to both sides of the equation :

q = 6

Supplement : Solving Quadratic Equation Directly

Solving q2-4q-12 = 0 directly

Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula

Parabola, Finding the Vertex:

3.1 Find the Vertex of y = q2-4q-12

Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 1 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Aq2+Bq+C,the q -coordinate of the vertex is given by -B/(2A) . In our case the q coordinate is 2.0000

Plugging into the parabola formula 2.0000 for q we can calculate the y -coordinate :

y = 1.0 * 2.00 * 2.00 - 4.0 * 2.00 - 12.0

or y = -16.000

Parabola, Graphing Vertex and X-Intercepts :

Root plot for : y = q2-4q-12

Axis of Symmetry (dashed) {q}={ 2.00}

Vertex at {q,y} = { 2.00,-16.00}

q -Intercepts (Roots) :

Root 1 at {q,y} = {-2.00, 0.00}

Root 2 at {q,y} = { 6.00, 0.00}

Step-1 : Multiply the coefficient of the first term by the constant 1 • -12 = -12

Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -4 .

-12 + 1 = -11

-6 + 2 = -4 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 2

q2 - 6q + 2q - 12

Step-4 : Add up the first 2 terms, pulling out like factors :

q • (q-6)

Add up the last 2 terms, pulling out common factors :

2 • (q-6)

Step-5 : Add up the four terms of step 4 :

Find ℎ(x) = f(x) − g(x)

I need to know what f(x) and g(x) is first

**Answer:**

h(x) = 7x - 3

**Step-by-step explanation:**

f(x) = 4x − 1 and g(x) = −3x + 2

h(x) = f(x) - g(x)

h(x) = 4x - 1 - (-3x + 2)

h(x) = 4x - 1 + 3x - 2

Which expression can be used to find the surface area of the following triangular prism?

5

2.

11

8.

**Answer:**

214.

**Step-by-step explanation:**

To get Surface area take

(cross section area) × 2 +(perimeter of crossection area × length)

the cross section area is a triangle

so area of a triangle =1/2 base times height

1/2×8×2=8

let's get perimeter of cross section

the cross section is still at triangle so let's find its perimeter.

5+5+8=18

18×length of which is 11

18×11=198

and 188 + 16=214. that's the answer

**Step-by-step explanation:**

even roots bounce at (0,0)

negative leading coefficient: initial graph descending to right, curve up

4 local extremes means remaining 5 degree of the function

The **function** F(x) = - x⁷ + 4x³ - 2x² could have created the given **graph**. which is the correct **answer** would be an **option** (**B**).

A graph can be defined as a **pictorial** representation or a diagram that represents **data** or values.

To create a **graph** of the **function** F(x) = - x⁷ + 4x³ - 2x², you can follow these steps:

Choose a **range** of x-values to use for the graph. For example, you might choose x = -2, -1.5, -1, -0.5, 0, 0.5, 1, 1.5, 2.

Substitute each** x-value** into the function to find the corresponding y-value. For example, if x = -1, then y = F(-1) = - (-1)⁷ + 4(-1)³ - 2(-1)² = -1 + 4 + 2 = 5.

Plot the **points** (x, y) on a coordinate plane. For example, you would plot the point (-1, 5) on the coordinate plane.

Connect the points with a smooth curve to create the graph of the function.

Therefore, we can conclude that** function** F(x) = - x⁷ + 4x³ - 2x² could have created the given **graph**.

Which values from the set negative 6, negative 4, negative 3, negative 1, zero, 2, satisfy this inequality?

Negative one half x, plus 3, is greater than or equal to 5.

**Answer:**

- 6

**Step-by-step explanation:**

- [tex]\frac{1}{2}[/tex] x + 3 ≥ 5 ( subtract 3 from both sides )

- [tex]\frac{1}{2}[/tex] x ≥ 2 ( multiply both sides by 2 to clear the fraction )

- x ≥ 4

Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.

x ≤ - 4

George has $3 in his savings account. He then adds $4 per day to the account. Let y represent the total amount in the account after x days.

Which equation represents this situation in the form of y=mx+b ?

Question 9 options:

y = 4x + 3

y = 3x + 4

y = 3/4x - 3

y = 4/3x - 4

**Answer:**

The answer is the 1st option, y = 4x + 3

**Step-by-step explanation:**

x is the amount of days that the 4 dollars will be multiplied by

( 4 * x )

The + 3 is the money that George already had in his savings account, so that money will be added to the total amount in his savings account.

( 4x + 3 )

Lastly, the y stands for the total amount of money in his savings account so the answer is the 1st option.

y = 4x + 3

Write the slope-intercept form of the equation of the line.

The slope- intercept of the line is y= x + 2. This is because for every time you go up or “rise” 1 unit you move to the right or “run” 1 unit. Therefore, 1/1 is just 1 so we can just leave this as x, however 1x would still work. Also, the line first touches the y-axis when x is 0 and y is 2. Therefore, the slope intercept is 2. So the slope intercept form of this line is still y = x + 2.
