Answer:

k=4

Step-by-step explanation:

−4k+6−2k=−3(4k−10)

−4k+6−2k=−3(4k−10)

−4k+6+−2k=(−3)(4k)+(−3)(−10)

−4k+6+−2k=−12k+30

(−4k+−2k)+(6)=−12k+30

−6k+6=−12k+30

−6k+6=−12k+30

−6k+6+12k=−12k+30+12k

6k+6=30

6k+6−6=30−6

6k=24

6k/6=24/6

Using factorization, the factors of 2 x²+x-28 are x = - 4 and x = 7/2

The factorization approach simplifies any algebraic or quadratic equation by using the fundamental factorization formula, which represents the equations as the product of factors rather than extending the brackets. Any equation may have an integer, a variable, or the algebraic expression itself as a component.

Given equation is -

2 x²+x-28

we will use the method of factorization.

⇒ 2x² + 8x -7x -28

⇒ 2x(x+4) - 7(x+4)

⇒ (x+4) (2x - 7)

The angles which form a linear pair are 40° and 140°.

Linear pair is defined as the pair of angles which add up to 180 degrees.

When two straight lines intersect with one another then 4 angles are formed. Any two adjacent angles thus formed are a linear pair.

Let us consider one angle be x . Now another angle is 3.5 times this angle.

Therefore measure of second angle = 3.5x

Now if these two angles are a linear pair then their sum will be equal to 180°.

Therefore we can form a linear equation in x and solve to get the values of the angles.

∴3.5x + x = 180°

or, 4.5x = 180°

or, x = 180 ÷ 4.5

or, x = 40°

Measure of the second angle = 3.5 × 40° = 140°

Hence the two angles which form a linear pair are  40° and 140° .

The quotient of 30 × 10⁻²⁴/5 × 10⁻²⁴ in scientific notation is equal to: C. 6 x 10^0.

Quotient can be defined as a mathematical expression that is simply used to represent the division of a number by another number.

In Mathematics, laws of indices can be defined as the standard principles and rules that are used for simplifying a mathematical equation or expression that involves powers of the same base.

By applying the laws of indices, the quotient is given by:

Quotient = 30 × 10⁻²⁴/5 × 10⁻²⁴

a)The acceleration, in km/h², in the first 15 mins = 200  km/h².

b) The distance between the two cities = 125 km.

c) The average speed during 20 the journey =  62.5  km/hr.

For the given question;

Every horizontal block is 1/8 hour = 7.5 minutes long.

Each vertical block has a speed of 10 km/hr:

The table drawn as per the data given in the table:

Time                    Velocity  km/hr

0 Min  ( 0 hr)   --->         0

15 Min (1/4 hr)   -->       50

45 Min (3/4 hr)  -->      50

60 MIn  ( 1 hr)      -->    100

90 Min  ( 3/2 hr)   --->  100

120 Min ( 2hr)     --->    0

The formula for acceleration:

Part a: Acceleration = final velocity - initial velocity / final time - initial time

Acceleration in the first 15 minutes:  (1/4 hr)  =  (50 - 0)/(1/4 - 0)  

= 50/(1/4)

=200

Thus, acceleration in the first 15 minutes is 200 kmph.

Part b: Distance among two cities:

= (1/2)(0 + 50)(1/4 - 0)  + 50 * (3/4 - 1/4)  + (1/2)(50 + 100)(1 - 3/4)  + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)

=  25/4  + 25 + 75/4   + 50 + 25

= 125

The difference distance for two cities is 125 kilometers.

Part c: Average speed = distance/2

Average Travel Speed = 125/2 = 62.5 km/hr

Therefore,

a: Acceleration in the first 15 minutes = 200  km/h²

b: The distance between two cities is 125 kilometers.

c: The average speed of the journey is 62 miles per hour.

Tristian and Barry both are correct as 9,32 is a rational and terminating decimal.

A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

A terminating decimal is a decimal number with a finite number of digits after the decimal point. The repeating decimal 5.6500000000... can be used to represent a terminating decimal like 5.65, however, when it is zero, the value is typically referred to as terminating.

A decimal number having a limited number of digits following the decimal point is referred to as a terminating decimal. Therefore, all decimal numbers that terminate are rational numbers.

Answer:

option D for you I have brainly plus and that's the answer I got.

The average rate of change of fuel efficiency = -3 gallon per hour

Fuel efficiency of the cooper when driving at a speed of 75 mph = 29 miles per gallon

Fuel efficiency of the cooper when driving at a speed of 60 mph = 34 miles per gallon

Let y₁ = 75 mph, y₂ = 60 mph

and x₁ = 29 miles/gallon , x₂ = 34 miles /gallon

Then the average rate of change of fuel efficiency = (y₂-y₁)/(x₂-x₁)

                                                        = (60 - 75)/(34-29)

                                                        = -3 gallon per hour

Converting the radicals into exponent numbers, √3 (⁴√3) = ⁴√27

To work with radical numbers or roots, it is easier to express them in exponent:

[tex]\sqrt[n]{a^{b}}=a^{\frac{b}{n}[/tex]

Recall the rules of exponent operations:

Note that the first 3 rules use the same base. If there are more than 1 base number, then group the exponent that have the same base first.

Example:

[tex](2^{3}.3^{-2}) : (2^{-3}.3^{2})=( 2^{3}:2^{-3}).(3^{-2}:.3^{2})[/tex]

Tips: To simplify exponent numbers, sometimes it is useful to modify the base whenever possible.

Example:

8².2⁻⁵ = (2³)². 2⁻⁵ = 2⁶. 2⁻⁵ = 2⁶⁻⁵ = 2¹ = 2

The given problem:

Simplify  √3 (⁴√3)
