Answer:
it should be 3(6x+5)
Step-by-step explanation:
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)
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.

An axiom of predicate calculus is the foundation of predicate calculus that is based on a fundamental and obvious principle or statement
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.

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

Step-by-step explanation:
If line l is parallel to line m, therefore:
(180° - 130°) + 101° + x° = 180° (angles on a straight line)
50° + 101° + x° = 180°
151° + x° = 180°
x = 180° - 151° (substraction property of equality)

What is (f−g)(x)? f(x)=3x5+6x2−5 g(x)=2x4+7x2−x+16
Answer: We have f(x)=3x⁵+6x²-5 and g(x)= 2x⁴+7x²-x+16
(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

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

A 40" screen television at a popular electronics retailer is priced at $600. The wall mount for this sized television costs $29.99.
Part A: If Jamie purchases the television and the wall mount and has a coupon for 30% off, how much will her subtotal be? Show all necessary work. (4 points)
Part B: If Jamie makes the purchase in a state with a 7% state sales tax, what will her final total be? Show all necessary work. (2 points)
Part C: The electronics retailer is extending a special offer to install the wall mount and television for free. However, Jamie decides to tip the installation specialist 10% of the original purchase price before the discount is applied. How much would her new total be, including tax, discount, and tip? Show all necessary work. (4 points)
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

on a larger map the coordinates for the location of another Washington DC landmark are eight and -10 in which quadrant of the map in this landmark located explain
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. An exponential function is defined as one where the output increases by a constant factor for each increase in the input.
