7-89. For angle α in the first quadrant, . Use that information to find each of the
following values without using a calculator. Be prepared to share your strategies with the class.
a. sin α
b. sin(π + α)
c. cos(2π − α)
The required values are for the given angle, as follows: a. sin α is positive. b. sin(π + α) = -sin α. c. cos(2π - α) = cos α.
What is the quadrant?A quadrant is defined as an area contained by the x and y axes, which there are four quadrants in a graph.
a. For an angle α in the first quadrant, sin α is positive.
Since the first quadrant is between 0 and 90 degrees, sin α is equal to the opposite side divided by the hypotenuse, where the opposite side is the y-coordinate and the hypotenuse is the distance from the origin to the point on the unit circle corresponding to the angle α.
b. sin(π + α) = sin (π - α). In the second quadrant (90 < α < 180), sine is negative, so sin(π + α) = -sin α.
c. cos(2π - α) = cos α. The cosine function has period 2π, so cos(2π - α) = cos α.
Since the first quadrant is between 0 and 90 degrees, cos α is positive.

The measure of the missing angle in a triangle is C = 18°.
What is a 45-Degree Angle?An acute angle is one that is 45 degrees. It is a 90-degree angle or half of a right angle. Look at the illustration of the 45-degree angle. Angles are expressed in degrees or radians.
A straight angle is one in which the two arms extend in precise opposition to one another. A 180° angle is a straight angle. A protractor can be used to measure angles; a straight angle is an angle that is measured at 90 degrees.
The two arms are perpendicular to one another at a right angle. Each angle measures 45° when the right angle is divided into two equal pieces. An acute angle is one that is 45 degrees. It is a 90-degree angle or half of a right angle.
Given one of the angles A = 45°
And B is 65% of the total angle sum = 65/100 × 180
= 117°
For angle C, using angle sum property
⇒ A + B + C = 180°
⇒ 45° + 117° + C = 180°
⇒ C = 180° - (45° + 117°)
⇒ C = 180° - 162°
⇒ C = 18°
Thus, The measure of the missing angle in a triangle is C = 18°.

Dave has inherited an apple orchard on which 70 trees are planted. Under these conditions, each tree yields 10 bushels of apples. According to the local WSU extension agent, each time Dave removes a tree the yield per tree will go up 0.45 bushels. Let x be the number of trees in the orchard and N the yield per tree. (a) Find a formula for N in terms of the unknown x. (Hint: Make a table of data with one column representing various values of x and the other column the corresponding values of N. After you complete the first few rows of the table, you need to discover the pattern.) 41.5 – 0.45x x (b) What possible reason(s) might explain why the yield goes up when you remove trees? removing trees will mean that you will be able to share more nutrients for the trees that are left, which produces more apples per tree, and better quality of the apples as well. The yield increases as the quality and care increases for the trees.
X = 88.1. The total of all interest, dividends, or other income that an investment provides divided by the age of the investment or the period over which the investor has held it is the average yield on an investment.
What is average yield?
The average yield on an investment or a portfolio is calculated by dividing the total interest, dividends, or other income received by an investment by the investment's age or the period over which the investor has held it. In particular, it alludes to yield, or the total revenue from an investment divided by the number of years kept.
There are numerous yield kinds, and the calculating process varies depending on the specific yield type and the type of security. Because of these variations, comparisons of yields between other financial product categories should be used with caution.
In the case of stocks, yield is determined by dividing the price rise plus dividends by the original purchase price. Both cost yield and current yield can be used to examine bond yield.
Given data :
Let x be the number of trees in the orchard and N the yield per tree.
No of trees = 70
yield = 10
formula for N in terms of the unknown x :
(10+(70-x)0.55)

The sum of four consecutive odd integers is 264. Find the integers.
The smallest of the four consecutive integers is?
Answer:
63
Step-by-step explanation:
Consecutive odd integers increase by the addition of 2 therefore if the smallest value is x then the next odd number is x + 2
So therefore; x + x + 2 + x + 4 + x + 6 = 264
Collect like terms
x + x + x + x + 2 + 4 + 6 = 264
4x + 12 = 264
4x = 264 - 12
4x = 252
Divide both sides by 4
x = 63
Therefore the smallest of the four consecutive integers is 63
two sides of a triangle are 19.75 and 10.25. select all choices that could represent the third side of the triangle.
the two possible values for the third side of the triangle are 22.5 and 24.00.
We know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore, the third side must be greater than 10.25 and less than 19.75.
From this, we can conclude that the third side of the triangle must be either 22.5 or 24.00.
We know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Given that two sides of the triangle measure 19.75 and 10.25, the third side must be greater than 10.25 and less than 19.75. Therefore, the only two possible lengths for the third side of the triangle are 22.5 and 24.00. Any length greater than 19.75 or less than 10.25 would not satisfy the triangle inequality and would not be a valid third side for the triangle. Thus, We know that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
the two possible values for the third side of the triangle are 22.5 and 24.00.

c. (15.5, 45, 20.5) will not create a triangle.
What is a triangle?
A triangle is a polygon with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified by their sides (such as equilateral, isosceles, or scalene) or by their angles (such as acute, right, or obtuse).
The set of lengths (3,4,5) will create a triangle. This is because it follows the "triangle inequality theorem" which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
The set of lengths (10, 20, 30) will not create a triangle. This is because 10 + 20 is less than 30, so it does not satisfy the triangle inequality theorem.
The set of lengths (15.5, 45, 20.5) will not create a triangle. This is because 15.5 + 20.5 is less than 45, so it does not satisfy the triangle inequality theorem.
Hence,
a. (3, 4, 5) will create a triangle.

Katie is mixing a new blend of perfume. Her formula calls for 12% lavender solution. She has two bottles. One is 15% and the other is 6%. How many ounces of each does she need to make 18 ounces of 12%?
On solving the equation, it is seen that about 12 ounces of the 15% solution must be mixed with about 6 ounces of the 6% solution to get 18 ounces of the 12% perfume.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Let x = number of liters of the 15% solution
Let 18 − x = number of liters of the 6% solution
Solution Ounces Strength Amount of Perfume
15% x 15 15x
6% 18 - x 6 6(18 - x)
Mixture 18 12 (18)(12)
So, the equation will be -
(amount of perfume in 15% solution) + (amount of perfume in 6% solution) = (amount of perfume in mixture)
15x + 6(18 − x) = (18)(12)
Solve the equation using distributive property -
15x + 108 - 6x = 216
Combine the like terms -
15x - 6x = 216 - 108
Simplify the equation further -
9x = 108
x = 108/9
x = 12
Now, substituting the value of x in 18 − x = 18 - 12 = 6.
Therefore, the amount in ounces is obtained as 12 ounces and 6 ounces.

The graph in the upper left corner best shows the population size of a K-selected species over time in a stable environment.
This graph shows the population of the species increasing at a slow rate until it reaches the carrying capacity of the species (the dashed line). After reaching the carrying capacity, the population of the species remains relatively stable, fluctuating slightly around the carrying capacity. This is evidence of a K-selected species, which tend to have a higher carrying capacity and longer life spans, and the population size remains relatively stable over time in a stable environment. Mathematically, this can be expressed as y = K = C, where y is the population size, K is the carrying capacity, and C is the constant value of the carrying capacity.

a wall 10 m long 1m high and 1/2 m wide is to be made of bricks . The bricks are of size 10 multiply 10 multiply 20 . how many bricks will be needed to make the wall.
To find out how many bricks are needed to make the wall, we need to find the total area of the wall and divide it by the area of one brick.
The area of the wall is:
length x height x width = 10 m x 1 m x 0.5 m = 5 m^2
The area of one brick is:
10 cm x 10 cm x 20 cm = 2000 cm^3
To convert the area of the wall from square meter to cubic centimeter, we need to multiply it by 100*100 = 10000.
5 m^2 x 10000 = 50000 cm^2
Now we can divide the total area of the wall by the area of one brick to find out how many bricks are needed:
50000 cm^2 / 2000 cm^2/ brick = 25 bricks
So, 25 bricks will be needed to make the wall.

a. 17, 15, 8 this can be a right triangle, while b. 7 25 19 is not a right a triangle
How to know when triangles are formedThere are an endless number of triangles produced when no side is specified.
The three angles produce an unlimited number of distinct triangles if side lengths are not provided.
When the three sides are specified the sides will be such that addition of the two smaller sides will be greater than the third side
For a. 17, 15, 8
the two smaller sides are:15 and 8
15 + 8 > 17
this can be a triangle
For b. 7, 25, 19
the two smaller sides are:7 and 19
7 + 19 > 25
this can be a triangle
For a right triangle the Pythagoras rule should be observe: the squire of the smaller sides will be equal to the square of the longer side. let the longer side be x
x² = 15² + 8²
x² = 225 + 64
x² = 289
x = √289
x = 17
this is a right triangle
x² = 7² + 19²
x ² = 49 + 361
x² = 410
x = √410
x = 20.25
this is not a right triangle

construct the general solution of involving complex eigenfunctions and then obtain the general real solution. describe the shapes of typical trajectories.
The ODE's general solution has real solution and complex eigen functions. Typical trajectories are sinusoidal curves.
The general solution of the ODE involves complex eigenfunctions, which are solutions of the form e^(ikx), where k is a real number and i is the imaginary unit. By combining these complex eigenfunctions with real coefficients, a general real solution can be obtained. Typically, these solutions will take the form of sinusoidal curves, with the amplitude and period determined by the coefficients of the eigenfunctions. The coefficients can be determined using initial conditions, allowing for more specific trajectories to be determined. For example, if the initial condition is known, then the coefficients of the eigenfunctions can be determined using Fourier analysis, allowing for the trajectory of the system to be determined.

of this
line.
y = [? ]x + [ ]
Simplify your answer and enter as an integer.
Answer:
y=-3x+4
Step-by-step explanation:
If we use rise over run from one point to the next, you will see that you rise vertically 3 units, then run horizontally 1 unit.
Then Make the rise negative because this is a negative graph. So -3/1
Divide -3 by 1. -3/1=-3. mx=-3
Now we have to find the y-intercept. This is where the graph crosses/intersects the y-axis. As if you look at the y-axis, you will see that the graph intersects the y-axis at (0,4).
So your y-intercept is 4. b=4.

What is the Slope-Intercept Form of a Linear Equation?When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilized (0, b). The y value of the y intercept point is represented by b in the equation. A line's equation can be written in the slope-intercept form such that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are instantly visible. A common name for this form is the y = mx + b form.We are given the dollar value [tex]$\$ 72.95$[/tex] of a product in 2010 and it is changed [tex]$\$ 5.15$[/tex] increase per year.
We are asked to write a linear equation that gives the dollar value V of the product in terms of the year t.
The general linear equation for this case would be,
[tex]$$V=C+5.15 t$$[/tex]
Since the dollar value increases by [tex]$\$ 5.15$[/tex]per year, the slope is[tex]$5.15$[/tex]. And, C is the V-intercept (the value of V when t=0 ).
Let us first determine the value of $C$ by substituting the given dollar value $ 72.95 in 2010 . This gives us:
[tex]V & =C+5.15 t \\[/tex]
[tex]72.95 & =C+5.15(10) \\[/tex]
[tex]72.95 & =C+51.5 \\[/tex]
[tex]72.95-51.5 & =C+51.5-51.5 \\[/tex]
[tex]21.45 & =C[/tex]
[Given that[tex]$\mathrm{t}=10$[/tex] at 2010
[Subtract 51.5 to both sides]
Thus, the value of C=21.45.
Let us substitute the value of C in the Eqn(1):
[tex]$$V=21.45+5.15 t$$[/tex]
Therefore, the linear equation is [tex]$V=21.45+5.15 t$[/tex].
