9x - 4 + 4x + 5x + 19
Which expression is equivalent to Jackson's expression?
0 3(6x + 5)
0 18x + 23
05(x + 2)
0 14x + 19

Answers

Answer 1

Answer:

it should be 3(6x+5)

Step-by-step explanation:

Answer 2

3(6x + 5) will  be equivalent expression of 9x - 4 + 4x + 5x + 19 so option (A) will be correct.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

Given the expression,

9x - 4 + 4x + 5x + 19

By adding variables and constants individually

(9x + 4x + 5x) + (-4 + 19)

⇒ 18x + 15

Taking common 3

⇒ 3(6x + 5)

Hence "3(6x + 5) will  be equivalent expression of 9x - 4 + 4x + 5x + 19".

If sin x=0.2, write down the values for sin (pi-x)

Answers

If the value of sin x = 0.2, then the values for sin(π - x) is 0.2.

Given that,

the value of sin x = 0.2

We have to find the value of sin(π - x).

We know the trigonometric rule that,

sin(π - x) = sin (x)

for any value of x.

So here whatever the value of x, the value of  sin(π - x) is sin (x) itself.

So here sin x = 0.2.

So, by the rule,

sin(π - x) = sin (x) = 0.2

Hence the value is 0.2.

What is the axiom of calculus?

The foundation of predicate calculus is based on a fundamental and obvious principle or statement known as an axiom.

The aforementioned axioms act as a foundation for deducing rational conclusions and evidence within the domain of predicate calculus.

Universally accurate and accepted without the need for additional reasoning is how they are commonly perceived.

The fundamental regulations and connections that oversee quantifiers, predicates, and logical operations, including conjunction, disjunction, and implication, are determined by the axioms of predicate calculus. They offer a sturdy groundwork for rationalizing statements that involve variables, quantification, and logical connectors in formal systems of logic.

What is Expression?

An expression is combination of variables, numbers and operators.

Logarithm, the exponent or power to which a base must be raised to yield a given number.

Given that  log 4= 1.386 and log 8 = 2.079

Find the length of a chord which is at a distance of 4 cm from the centre of the circle of radius 6cm.​

Answers

Answer:

4√5 cm

Step-by-step explanation:

Connect the two points at which the chord touches the circle to the center - these are radii.

We know that the chord is 4cm from the center of the circle.

So we now have an isosceles triangle with height of 4cm and congruent side lengths of 6cm (see attached diagram for visual representation). An isosceles triangle is made up of 2 congruent right triangles.

To find the length of the chord, all we have to do is calculate the shorter leg of one of the right triangles and multiply it by 2.

Use Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs and c is the hypotenuse of a right triangle).

Therefore, a² + 4² = 6²

                 a² + 16 = 36

                        a² = 36 - 16 = 20

                          a = √20 = 2√5

So the length of the chord = 2 x 2√5 = 4√5 cm

Find the length of a chord which is at a distance of 4 cm from the centre of the circle of radius 6cm.

3.007 as a fraction is equal to 3 7/1000.

The three is to the left of the decimal point so it is a whole number, which makes the fraction a mixed number.

The 7 is three places to the right of the decimal point, which when multiplying 10^3 will result in 1,000. Therefore, the denominator is 1,000.

3.007 as a fraction is 3 7/1000.

                        (f-g)(x)= 3x⁵-2x⁴-x²+x-21

Step-by-step explanation:

Here we have,

Given : f(x)=3x⁵+6x²-5 and g(x)= 2x⁴+7x²-x+16

We know,

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

= (3x⁵+6x²-5 ) - ( 2x⁴+7x²-x+16)

On subtracting g(x) from f(x) we get,

(f-g)(x)= (3x⁵+6x²-5  - 2x⁴-7x²+x-16)

On simplify,

 (f-g)(x) =3x⁵-2x⁴-x²+x-21

Hence,

(f-g)(x) = f(x) - g(x) = 3x⁵-2x⁴-x²+x-21

What is the average velocity of a car that .5 hours to drive across Olathe, a distance of 6
miles?

Answers

Average velocity of a car that drive across Olathe is 0.536m/s

Average velocity is defined as a change in position or displacement divided by the time interval in which displacement happened. The average velocity can be positive or negative. The SI unit of Average velocity is meter / seconds

Average velocity = distance / time

Distance given = 6 miles

changing miles into meters by multiplying with 1609.344

Distance in meter = 9656 meters

Time taken = 5 hours

changing hours into seconds by multiplying with 3600

Time in seconds = 18000 seconds

Average velocity = 9656 / 18000

Answers

Jamie's subtotal will be $440.99Jamie's total will be $471.86Her new total  including tax, discount, and tip will be $531.86Cost estimation

The cost of the television and wall mount before discount is $600 + $29.99 = $629.99

After a 30% discount, the subtotal is:

$629.99 x 0.70 = $440.99

The sales tax is 7% of the subtotal:

$440.99 x 0.07 = $30.87

The final total is the subtotal plus the sales tax:

$440.99 + $30.87 = $471.86

The original purchase price before discount is $600.

10% of $600 is $60.

So Jamie decides to tip the installation specialist $60.

After the discount, the subtotal is $440.99 (as calculated in Part A).

The sales tax is 7% of the subtotal:

$440.99 x 0.07 = $30.87

The new total is the subtotal plus the sales tax and the tip:

$440.99 + $30.87 + $60 = $531.86

Answers

The other Washington DC landmark with coordinates (8,-10) is located in the fourth quadrant of the map.

To determine in which quadrant of the map a point with coordinates (8,-10) is located, we need to look at the signs of the x and y coordinates.

Since the x-coordinate (8) is positive and the y-coordinate (-10) is negative, this point is located in the fourth quadrant.

In general, the four quadrants of a Cartesian coordinate system are divided by the x and y-axes.

The first quadrant is located in the upper right-hand corner and contains points with positive x and y coordinates.

The second quadrant is located in the upper left-hand corner and contains points with negative x and positive y coordinates.

The third quadrant is located in the lower left-hand corner and contains points with negative x and y coordinates.

Finally, the fourth quadrant is located in the lower right-hand corner and contains points with positive x and negative y coordinates.

\(f(x) = 2x is linear.f(x) = 4^x is exponential.\) This is where at each level, each branch extends into 4 branches.

In the first prompt, the number of boxes in each row is increasing by a constant amount, so the function is linear. In the second prompt, the number of branches is increasing by a factor of 4 with each level, so the function is exponential.

A linear function is defined as one where the output increases by a constant amount for each increase in the input.
