What is called composite function?

Let's start by using the provided information to formulate an equation.

Kelly starts with $800 in her savings account, so this is the initial amount. She makes $340 per week, 15% of which is invested into her savings account for 8 weeks, so this information will form a rate. Kelly also withdrew (subtracted) 45 dollars 3 times. Now, let's form the equation.

y=8(.15·340)+800-45(3), where y=remaining balance after 8 weeks. Now, lets simplify the equation using Orders of Operations.

Simplify parenthesis first:

y=8(.15·340)+800-45(3)

y=8(51)+800-45(3)

Complete any multiplication:

y=8(51)+800-45(3)

y=408+800-135

Add and subtract from left to right; addition and subtraction are not separate steps and must be done in the same step, so we work left to right as to whichever comes first:

y=408+800-135

y=1208-135

y=1,073

Remember that y is the remaining balance after 8 weeks. This means that $1,073 dollars is the balance after 8 weeks.

Hope that helps, and feel free to give Brainliest!

The account balance at the end of 8 weeks is $1073.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Kelly has a savings account with a beginning balance of $800 and she earns $340 per week.

Therefore, 15% of her weekly earnings for 8 weeks is,

= (15/100)×340×8.

= $408.

Again, She made $45 withdrawals 3 times, which is,

= 3×45.

= $135.

Therefore, The final amount in her account after 8 weeks is,

= $(800 + 408 - 135).

= $1073.

The best option regarding the solutions of the trigonometric equation presented in this problem is given as follows:

A. 60º + n360º, 300º + n360º.

The trigonometric equation for this problem is defined as follows:

[tex]\cos{x} - \sqrt{1 - 3\cos^2{x}} = 0[/tex]

Then, isolating the cosine, we have that:

[tex]\cos{x} = \sqrt{1 - 3\cos^2{x}}[/tex]

Applying the square for both sides, we have that:

cos²(x) = 1 - 3cos²(x).

4cos²(x) = 1.

cos²(x) = 1/4

cos²(x) = 0.25.

Applying the square root to both sides, we have that:

cos(x) = 0.5.

Meaning that the angle measures of x with the cosine of 0.5 are given as follows:

x = 60º, x = 300º.

(as the cosine is positive on the first and fourth quadrant).

One entire lap over the unit circle is equivalent to 360º, hence adding 360º n times to any of these solutions is also a solution to the trigonometric equation, meaning that option a is correct.

Answer:

The tower is 113 meters.

Step-by-step explanation:

We are given a pole and a tower that both create a shadow.

Hence, the figures made are triangles.

If you draw the figure (attached to this response), you can see the two triangles are similar triangles.

⭐What are similar triangles?

The length of the height of the pole (3.2) corresponds to the length of the height of the tower (x).

The length of the shadow of the pole (1.32) corresponds to the length of the shadow of the tower (46.75).

Therefore, our two ratios are:

[tex]\frac{3.2}{x}[/tex] and [tex]\frac{1.32}{46.75}[/tex]

A proportion is when you set two ratios equal to each other:

[tex]\frac{3.2}{x} = \frac{1.32}{46.75}[/tex]

To solve for x, cross multiply by multiplying the opposite parts of the fraction together.

[tex]\frac{3.2}{x} = \frac{1.32}{46.75}\\46.75(3.2) = 1.32x\\149.6 = 1.32x\\\\113 = x[/tex]

∴ The tower is 113 meters tall!

To find the equation of a vector given a point and direction, you need to find the components of the vector and plug them into the equation: v = (x, y, z).

The equation of a vector is typically written like this:

v = (x, y, z)

To find the equation of a vector given a point and direction, you need to find the components of the vector and plug them into the equation. For example, let's say you are given the point (1,2,3) and the direction of the vector is (2,3,4). The components of the vector, v, would be x = 2, y = 3, and z = 4, so the equation for that vector would be:

The equation that represents the relationship of x number of badges to y dollars is y = 9x.

What is an equation?

A mathematical statement called an equation displays the equality of two mathematical expressions. Variables, coefficients, exponents, arithmetic operators, equal signs, and constants are some of the components that make up an equation.

 An equation is said to be linear if the maximum power of the variable is consistently 1.

Let the number of badges be x and the cost of x number of badges be y.

Answer:

y = -3x +20

Step-by-step explanation:

Equation of line: y =mx + b

Where m is the slope and b is the y-intercept.

3x + y = 17

Write the above equation in y = mx +b form.

      y = -3x + 17

m = -3

Parallel lines have same slope.

So, slope of the required line is (-3).

     y = -3x + b

This line is passing through (4,8). Substitute in the above equation and find the value of 'b'.

       8 = -3*4 + b

        8 = -12 + b

  8 + 12 = b

          b = 20

Equation of the line:

               [tex]\sf \boxed{ y = -3x + 20}[/tex]

y = 3/2x - 9/2

The equation of the line that passes through the points (4,-3) and (2,0) can be found using the point-slope form of a linear equation. The point-slope form of a linear equation is y-y1=m(x-x1), where m is the slope of the line and (x1,y1) is a point on the line.

To calculate the slope, we will use the formula m = (y2-y1)/(x2-x1). In this equation, (x1,y1) = (4,-3) and (x2,y2) = (2,0). Substituting these values into the slope formula, we get m = (0-(-3))/(2-4) = 3/(-2) = -1.5.

Now that we have the slope, we can plug the point (4,-3) and the slope (-1.5) into the point-slope form of a linear equation to get y-(-3)=-1.5(x-4). Simplifying this equation, we get y+3=-1.5x+6, which is the equation of the line that passes through the points (4,-3) and (2,0).

Therefore after using the Pythagorean Theorem and the properties of chords in a circle we got 626 when m+n is divided by 1000.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The longest side of a right-angled triangle, or the side across from the right angle, is called the hypotenuse.

Let M and N be the midpoints of chords AB and CD, respectively.

Let X and Y be the foot of the perpendicular from P to chord AB and CD respectively.

Since X,Y are on the circle and P is the midpoint of XY,

OP = PX = PY = radius = 25

Now, using the Distance Formula:

(XM)^2 + (YN)^2 = (12)^2

By the Pythagorean Theorem, on triangle PXN and PYM,

(25)^2 + (YN)^2 = (PN)^2 = (14/2)^2 and

(25)^2 + (XM)^2 = (PX)^2 = (30/2)^2

OP^2 = 625 = 25^2

For three line segments to form a triangle, they must satisfy the triangle inequality theorem. The triangle inequality theorem states that for any triangle, the sum of the lengths of any two sides of the triangle must be greater than the length of the third side.

This is because if the sum of the lengths of any two sides is less than or equal to the third side, it would not be possible to form a triangle with those side lengths, as the two shorter sides would not be able to reach the longer side to form the triangle.

In this case, the sum of the two shorter segments (12 units + 10 units) is 22 units, which is less than the measure of the longest segment (18 units). Therefore, the three segments will not form a triangle.

Velocity is a vector quantity that represents the rate of change of an object's position. It is defined as the displacement of an object divided by the time it takes for that displacement to occur. In other words, velocity tells you how fast an object is moving in a certain direction.

The standard unit for velocity is meters per second (m/s) or kilometers per hour (km/h) in the International System of Units (SI). In imperial system of units, it is expressed in feet per second (ft/s) or miles per hour (mph).

The formula for velocity is:

velocity = displacement / time

To convert 12 m/s to km/h, you can multiply 12 by the conversion factor:

12 m/s * (1 km/h / 0.277778 m/s) = 43.2 km/h

So 12 meters per second is equal to 43.2 kilometers per hour.
