please help asap!!!!!!!!!!!!!!!!!!!!!!!!!!!! piecewise function

Answer:

Step-by-step explanation:

Given two complementary angles labeled (4x)° and (x-5)°, you want an equation for finding x, and the measures of the two angles.

The equation will reflect the fact that the angles have a sum of 90°:

  4x +(x -5) = 90

The equation simplifies to ...

  5x -5 = 90

  5x = 95

  x = 19

  ∠1 = 4x° = 76° . . . . . . measure of larger angle

  ∠2 = (x -5)° = 14° . . . . . measure of smaller angle

__

Additional comment

The little square at the vertex of the angles means that is a right-angle corner. Its measure is 90°. The two angles 1 and 2 together make up that right angle. That is the relation you use to form the equation.

Rewriting (simplifying) the sum ...

  4x +(x -5) = 5x -5

tells you nothing about the value of x. Any value for x will satisfy this equation. In order to find x, you need to relate this sum to something other than itself. (There is a reason why the angle is marked as a right angle.)

In the equation for acceleration, a, equals final velocity - original velocity/time, acceleration would be negative if the numerator is negative.

The object is slowed down by the acceleration, which is acting against the motion. In this situation, your acceleration is negative. Positive value will be returned if your end velocity is lower than your initial velocity. The equation for acceleration can be related as:

Acceleration, a = [tex]v_{f}[/tex] - [tex]v_{i}[/tex] × [tex]\frac{1}{t}[/tex]

The general equation a = v/t denotes acceleration (a), which determines the change in velocity (v) over the change in time (t). This enables you to calculate the change in velocity in meters per second squared ([tex]m/s^{2}[/tex]). Since acceleration has both its magnitude and direvtion, it is a vector quantity.

Exponential growth and decay apply to quantities which change rapidly. Exponential growth and decay have been derived from the concept of geometric progression. Quantities that do not change as constant but change in an exponential manner can be termed as having an exponential growth or exponential decay.

Given here:

Now we know  For exponential growth, the value of b is greater than 1 (b > 1), and for exponential decay, the value of b is lesser than 1 (b < 1), where b is the growth factor and Exponential Growth f(x) = abˣ and Exponential Decay f(x) = ab⁻ˣ

1) f(x)=3×4ˣ

  Clearly b=4>1

Thus the function represents exponential growth.

2) f(x)=4×(1/4)ˣ

  Here b=1/4<1

∴ The function represents exponential decay.

3) f(x)=2×(1/2)ˣ

Again here the growth factor is b=1/2<1 , thus the function represents exponential decay.  

Similarly for equation 4 we have b=12>1 and thus the function represents  

exponential growth.

Hence, equation 1 and 4 represent exponential growth and equations 2 &3 represent exponential decay.

The sinusiodal function created from 2 given points is y = 3 sin (πx + 90) + 3

From the case, we have:

Minimum point = (-3,0)

Maximum point = (-9,6)

The sinusoidal fuction would be in the form of:

y = A sin (Bx - C) + D

where:

A = amplitudo

B = 2π / Period

C = Phase shift

D = Midline

First, we need to find the amplitudo:

A = (Y max - Y min) / 2

A = (6 - 0) / 2

A = 3

Periode = (X max - X min) x 2

Periode = (-9 - (-3) x 2

Periode = -6

B = 2π / Periode

B = 2π / 6

B = 1/3 π

D = (Y max + Y min) / 2

D = (6 + 0) / 2

D = 3

We can use one point to find the value of C:

0 = 3 sin (π/3 (-3) - C) + 3

0 = 3 sin (π - C) + 3

-3 = 3 sin (π - C)

sin (π - C) = -1

(π - C) = 270

C = -1/2 π

C = - 90

Three points can define a plane in a three-dimensional space.

Because a plane can be defined as a flat surface that extends infinitely in all directions, three points in space are sufficient to specify a plane. A plane can be determined by any three non-collinear points, i.e., points that are not on the same straight line, as long as they are not on the same line. Imagine three points in space, A, B, and C. We draw straight lines from A to C to create a plane. The triangle formed by these lines is a flat surface. A plane can be made by endlessly extending the flat surface in all directions.

The triangle formed by the three points A, B, and C, which are not collinear, extends in all directions to form a plane. A plane is therefore defined by three points. It's crucial to remember that any new point that lies on the same plane as A, B, and C will also be connected to the three defining points by the same straight line.

4 is not a perfect number because the sum of its factors (besides 4 itself), 1+2, is less than 4. Numbers like 4 are known as deficient numbers.

In number theory, a natural number is called deficient if it is greater than the sum of its divisors, excluding itself. For example, the number 8 is deficient because its divisors are 1, 2, and 4, and 1 + 2 + 4 = 7, which is less than 8. A number that is not deficient is called abundant.

The concept of deficient numbers was first studied by the ancient Greek mathematician Nicomachus of Gerasa in his work "Introduction to Arithmetic". He classified numbers into three categories: abundant, perfect, and deficient numbers. He defined a perfect number as a number whose divisors (excluding the number itself) sum up to the number and abundant if the sum of divisors (excluding the number itself) is greater than the number.

The study of deficient numbers is closely related to the study of divisors of numbers, which is a fundamental area of number theory. The study of deficient numbers also has connections to other areas of mathematics such as algebraic number theory and the theory of quadratic forms. In addition, the study of deficient numbers has applications in computer science and cryptography.

It is important to note that only a small percentage of numbers are deficient, and the study of deficient numbers is not as widely studied as the study of prime numbers or perfect numbers, but it is still an interesting area of research in number theory.

Answer:

C.) right and isosceles, but not equilateral

Step-by-step explanation:

Answer:

To find the equation of the line passing through the point (3,2) and parallel to line x + 2y = 5, we need to use the point-slope form of a linear equation. The point-slope form of a linear equation is: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

We know that two lines are parallel if they have the same slope. Since the given line x + 2y = 5 has a slope of -1/2, the equation of the line passing through (3,2) and parallel to x + 2y = 5 is y - 2 = -1/2 (x - 3), or simplifying y = -1/2x + 7/2

To find the equation of the line passing through the point (2,5) and parallel to the line x + 3y - 8, we need to use the point-slope form of a linear equation. The point-slope form of a linear equation is: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

We know that two lines are parallel if they have the same slope. Since the given line x + 3y - 8 has a slope of 1/3, the equation of the line passing through (2,5) and parallel to x + 3y - 8 is y - 5 = 1/3 (x - 2), or simplifying y = 1/3x + 1/3

It's important to note that the lines are parallel because they have the same slope and different y-intercept, which means that they will never intersect.

(h x $6.25) - $20 is a equation to figure how how many hair products she needs to sell to generate a profit of $120.

Profit is just the money left over after costs are paid. A loss is deemed to have occurred if the expenses exceeded the income.

A gain is a positive figure, whereas a loss is a negative one.

To determine whether a contract is lucrative or not, the phrases profit and loss are utilized. These words are frequently used in ordinary conversation. If the selling price exceeds the cost price, the difference between the two amounts is known as the profit.

The equation to determine how many hair products Jackie must sell to make a profit of $120 would be:

$120 (profit) = (h x $6.25) - $20 (cost of online membership)

where h is the number of hair products sold.

To solve for h, we can first add $20 to both sides of the equation:

$120 + $20 = h x $6.25

Next, we can divide both sides of the equation by $6.25 to find the value of h:

h = ( $120 + $20 ) / $6.25

h = 20

So Jackie must sell 20 hair products to make a profit of $120.

A right triangle is a triangle with one right angle (90 degrees). The hypotenuse of a right triangle is the side opposite the right angle and is usually the longest side of the triangle.

To find the area of the triangle, you will need to use the base and the height of the triangle. In this case, the base of the triangle is 48cm and the height is the length of the side opposite to the right angle.

To find the length of the side opposite to the right angle, you can use the Pythagorean Theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. The theorem can be written as:

c^2 = a^2 + b^2

where c is the hypotenuse, and a and b are the other two sides.

So, substituting the values we have:

50^2 = a^2 + 48^2

2500 = a^2 + 2304

a^2 = 2500 - 2304

a^2 = 196

a = 14

Area of the triangle = (1/2) * base * height

= (1/2) * 48 * 14

= 336 cm^2

So, the area of the triangle is 336 cm^2

The area of the triangle is 336 cm²

The area of a triangle can be found using the formula:

Area = (1/2) × base × height

In this case, we know the base is 48cm and the hypotenuse is 50cm. To find the height, we can use the Pythagorean theorem, which states that the square of the length of the hypotenuse (a) is equal to the sum of the squares of the lengths of the other two sides (a and b) in the right triangle.

c² = a² + b²

So in this case, we have:

50² = 48²  + b²

Solving for b, we get:

b =√ 50² - 48²

b = √2500 - 2304

b = √196

b = 14 cm

So the height of the triangle is 14cm.

Now we can use this information to find the area:

area = (1/2) ×48 ×14 = 336 cm²

Hence, we can say the area of the triangle is 336 cm²
