Answer:

last option

Step-by-step explanation:

Let's call the original angle x° and the radius of the circle y. The area of the original sector would be x / 360 * πy². The new angle, which is a 40% increase from x, can be represented as 1.4x so the area of the new sector is 1.4x / 360 * πy². Now, to find the corresponding change, we can calculate 1.4x / 360 * πy² ÷ x / 360 * πy² = (1.4x / 360 * πy²) * (360 * πy² / x). 360 * πy² cancels out so we're left with 1.4x / x which becomes 1.4, signifying that the area of the sector increases by 40%.

Use the formula a2 – b2 = (a b)(a – b) to factor completely. what are the factors of 36x8 – 49? (9x4 – 1)(4x2 49) (36x4 – 7)(x2

zimovet [89]

The factors of 36x^8 – 49 are (6x^4-7)(6x^4+7).

We are given to factor the following polynomial completely:

36x^8 – 49.

We have to find the complete factor of the given polynomial.

Completely factor means to continuously factor terms until they are in simple terms, meaning you are no longer able to factor

<h3>What is the formula for (a^2-b^2)?</h3>

The formula for (a^2-b^2)= (a+b) (a-b).

Therefore applying the given formula we have,

$F=(6x^4)^2-7^2$

$F=(6x^4)^2-7^2\\F=((6x^4)-7)(6x^4)+7)$

Thus, the required factors are

$F=((6x^4)-7)(6x^4)+7)$

Therefore,option (C) is correct.

Paladinen [302]

The number -15 represents in a negative integer

<h3>How to determine what -15 represents in integers?</h3>

The number is given as:

Number = -15

Integers are numbers that do not have decimal points

The categories of integers are:

Positive integers (i.e. numbers greater than 0)
Zero
Negative integers (i.e. numbers less than 0)

The given number -15 is less than 0

Hence, the number -15 represents in a negative integer

What is the slope of the line through (-5,-10) and(-1, 5)?

Mila [183]

Answer: The slope is 15/4.

Step-by-step explanation:

M = (y2 - y1)/(x2 - x1)

M = (5 - (-10))/(-1 - (-5))

M = (5 + 10)/(-1 + 5)

M = 15/4
