Option A, 65 + |−5| = 70°, 65° is the farthest from 0°

Here, we are given that.

The average temperature in the mountains is 65° in April.

The average temperature in that same spot is −5° in December.

Thus, the difference in the temperature will be-

65 - (-5)

= 65 + 5

= 70°

Therefore, this location is 70° warmer in April than in December.

Now, their distance from 0 will be-

|65 - 0| = 65

as distance cannot be negative, we look at only the absolute difference.

Similarly |-5 -0| = 5

Thus, we see that 65° is the farthest from 0°.

Hence, option A, 65 + |−5| = 70°, 65° is the farthest from 0°, is the correct answer.

The point-slope equation of something like the line, with slope equal to 5/6 but instead passing through the point at(22 , 12), is:

(y - 12) = 5/6(x - 22).

A line's equation can be stated in three different ways:

The typical form of a line equation is ax + by = c, where a but rather b are the coefficients of variables x and y, respectively, as well as c is a constant if all possible values must be integers. In the meantime, the slope-intercept form is given by the formula y = mx + b, where m is the line's slope as well as b is the y-intercept. Given the slope m and a point on the line (x, y), we can formulate the equation using point-slope form, (y - y1) = m. (x - x1).

To build up the equation, use the point slope form and enter in the values.

(y - y1) = m(x - x1)

where;

m = 5/6

(x1 , y1) = (22 , 12)

(y - 12) = 5/6(x - 22)

In slope-intercept form, the equation of the line is:

(y - 12) = 5/6(x - 22)

y - 12 = 5/6 x - 110/6

y = 5/6 x - 19/3

In standard form, the equation of the line is:

y = 5/6 x - 19/3

5/6 x - y = 19/3

Multiplying both sides by 6,

5x - 6y = 38.

The point-slope equation of something like the line, with slope equal to 5/6 but instead passing through the point at(22 , 12), is:

(y - 12) = 5/6(x - 22).

We need to know about percentage to solve the problem. The price of the pair of pants after discount but before tax is $19.8

Percentage of a number gives us a certain part of the quantity, suppose we say that 20% of 100 then we have 20. It can be defined as a given part in every hundred. In this question we know that the store Feng goes to buy a pair of pants offers 40% discount, which means that Feng can save 40% of the price of the pants. The original price on tag is given as $33, we have to find what 40% of $33 is and then subtract that amount from $33 to get the price of the pair of pants after discount but before tax.

Discount=[tex]\frac{40}{100}[/tex]x33=132/10=13.2

The price of the pants after discount =$(33-13.2)=$19.8

Answer:

The resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.

Step-by-step explanation:

It is given that the GCF of 48 and 30 to write the sum of the two numbers as the product of their GCF and another sum.

Now,

The largest number that can divide two numbers is known as the GCF. The formula for 48 plus 30 is as follows;

=> 48 + 30

=> 6 (8 + 5)

=> 6 (13)

=> 78

Here, the numbers are given as 48 and 30 so, the expression is;

=> 48 + 30

And their GCF is 6 so, we get;

=> 48 + 30 = 6 × 8 + 6 × 5

=> 48 + 30 = 6 (8 + 5)

=> 48 + 30 = 6 (13)

=> 48 + 30 = 78

Therefore, the resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.

The area of each card is 80.05cm^2, and the edge of each card is 8.95cm.

Priti chose a green coloured square paper of 20.5cm, since its a square the length and breadth of the card are equal

l = b

Recall the area of a square is

A = l^2

A = (20.5)^2

A= 20.5 × 20.5

A= 400.25cm^2

Since the paper is to be used for 5 cards, therefore the is divided in 5 equal cards. The are area of each card will be

A = A/5

A = 400.25/5

A = 80.05cm^2

The edge of each card is the side of the each card which can either be the length or the breadth since all the sides are equal for a square.

Recall that

A = l^2

Since the Area of each card is 80.05cm^2. Therefore,

80.05 = l^2

Finding the square root of both sides

(80.05)^1/2 = (l^2)^1/2

l = 8.947cm

The expression can be simplified through division of the exponential (power).

In the given expression, if the powers have the same base, we can actually divide the power.  In order to carry out the division of the exponential (power), we can subtract their exponential.

In the general form, a-m=1/am

As there are two different base terms x and y in the numerator and denominator, we will subtract the powers of x terms and powers of y terms.

Let us simplify the x terms,

x¹/₂÷x³/₄=x(1/2)-(3/4)  

Solving the powers,(½)–(¾)=(2/4)–(¾)=(2-3)/4=-1/4

x¹/₂÷ x³/₄=x(1/2)-(3/4)= x-1/4  

Let us simplify the y terms,

y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)

Solving the powers, (-1/3)-(1/2)=(-2/6)-(3/6)=-5/6

y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)=y-5/6

Putting the terms together gives us,

x-1/4 *y-5/6

It can be expressed as a fraction as a-m=1/am

x-1/4 *y-5/6=1/x1/4y5/6

Hence, x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂= x-1/4 *y-5/6=1/x1/4y5/6

All the roots of the polynomial 2x⁴+ x³-8x²- 4x = 0 are x = -2, x = -0.5, x = 0, x = 2 ( Option A ).

Given polynomial :

2x⁴+ x³-8x²- 4x = 0

The highest power of the polynomial is 4. This implies that this polynomial will have 4 roots or 4 zeroes.

There are numerous ways of finding roots or zeroes of a polynomial of any degree.

A root or zero of a polynomial is a solution or value of the variable which gives the value of the polynomial equal to 0.

Since this is a multiple choice based question, the easiest approach to this question is by eliminating options and finding the correct answer.

Option B and C get eliminated instantly because they have only three roots, however this is a polynomial of degree 4 and should have 4 roots.

For option A and C, we put x= -2, x = -0.5, x = 0, x = 2, and x = 0.5 in the given polynomial to check if the answer is equal to zero.

For x = -2, we get 2x⁴+ x³-8x²- 4x = 0

For x = 2, we get 2x⁴+ x³-8x²- 4x = 0

For x = 0, we get 2x⁴+ x³-8x²- 4x = 0

For x = -0.5, we get 2x⁴+ x³-8x²- 4x = 0

For x = 0.5, we get 2x⁴+ x³-8x²- 4x = -3.75

From this result, option C gets ruled out and all the values in option A check out as a root of the given polynomial.

Therefore, we get all the roots of the polynomial 2x⁴+ x³-8x²- 4x = 0 as x = -2, x = -0.5, x = 0, x = 2
