The value of cos θ from the unit circle is cos θ = 0.88235
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
Given data ,
The terminal side of angle θ intersects the unit circle in the first quadrant at ( 15/17,-8/17 )
So , the equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Substituting the values of x and y in the equation , we get
x = 15/17
And , y = -8/17
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
So , the value of cos θ = ( 15/17 ) and sin θ = ( -8/17 )
On simplifying the equation , we get
cos θ = ( 15/17 )
cost θ = 0.88235
Hence , the value of cos θ = 0.88235

(a) The double-dedining-balance rate
(b) The double-declining-balance
depreciation for the first year
%
a) The double-declining-balance rate is 0.5 or 50%.
b) The double-declining-balance depreciation for the first year is $53800.
What is depreciation?
Depreciation is an accounting procedure that allows a business to distribute an asset's cost over the course of its useful life. In other words, it keeps track of how an asset's value decreases over time. In order to better align an asset's productivity in use to its operating costs over time, businesses depreciate assets on their financial statements and for tax purposes.
The formula of the double-declining-balance rate is 2 × (1/useful life)
Given that the building acquired at the beginning of the year at a cost of $107,600 has an estimated residual value of $4,300 and an estimated useful life of 4 years.
The double-declining-balance rate is
= 2 × (1/4)

Julio’s car can travel 300 miles on one 12-gallon tank of gas. Viet’s car uses gas as described by the equation m=13g
, where m is the miles traveled and g is the gallons of gas used. Which statement is true?
The true statement is "viet's car can uses 13 gallons of gas for every miles it travels.
The correct answer choice is option B.
Which statement is true?Julio's car:
m = k × g
Where,
m = miles traveled
g = gallons of gas used
m = k × g
300 = k × 12
300 = 12k
divide both sides by 12
k = 300/12
k = 12

3. Find the slope between

the y-intercept and write the
equation of the line
(-2, 10),(-2,- 15)
Answer:
Step-by-step explanation:
The slope of a line can not be found between two points with the same x-coordinate, as division by zero is undefined. Hence, the line defined by the points (-2,10) and (-2,-15) is a vertical line and has no slope.
The y-intercept of a line is the point at which the line intersects the y-axis, i.e., the value of y when x=0. A vertical line does not intersect the y-axis, hence it has no y-intercept.
Since the line has no slope or y-intercept, its equation can not be written in the standard form of y = mx + b, where m is the slope and b is the y-intercept. Instead, the equation of the line can be written as x = constant, where constant is the x-coordinate of the points on the line, i.e., x = -2.

Answer:
D. The average rates of change of f and g cannot be determined from the given information.
Step-by-step explanation:
To determine the average rate of change of a function, we need the equation of the function. Since the equation of g is not given, we cannot determine the average rate of change of g and compare it with the average rate of change of f. Hence, option D is the correct answer.
If f(x) is a function which is continuous everywhere then we must have m= ?
The function is continuous only if m = 7.
How to find the value of m?If the function is continue, then the value of the function needs to be the same one in both pieces of the function when we evaluate in x = -2
That means that:
f(-2) = f(-2) (trivially)
Replacing the two pieces of the function we will get:
m*(-2) - 6 = (-2)^2 + 10*(-2) - 4
now we can solve that equation for m.
-2m - 6 = 4 -20 - 4
-2m = -20 + 6 = -14
m = -14/-2 = 7
m = 7
that is the value of m.

The solution of the system of equations is (8, 11).
What is the solution of the system of equations?We know that one of the equations of the system is:
y = x + 3
And the other line passes through the points (3, 1) and (4, 3), then the slope of that line is:
a = (3 - 1)/(4 - 3) = 2
So the line is something like:
y = 2*x + b
To find the value of b, the y-intercept, we can replace the values of one of the points.
I will use (3, 1)
1 = 2*3 + b
1 = 6 + b
1 - 6 = b
-5 = b
So the other line is y = 2x - 5
Then the system of equations is:
y = x + 3
y = 2x - 5
Now we can solve the system:
x + 3 =2x - 5
3 + 5 = 2x -x

y = x + b
The point where the graphs of two equations intersect has y-coordinate 2.
So, we have
3x + 5 = 2
x + b = 2
Eliminate x
So, we have
3b - 5 = 6 - 2
Evaluate
3b = 9
So, we have
b = 3
hence, the equation is y = x + 3

The Imaginary part is [tex]& \frac{-5 \sqrt{3}-2}{4}[/tex]
What is complex number?A complex number can be represented in the form a + bi, where a and b are real numbers. A complex number is a part of a number system that extends the real numbers by adding an element designated by the symbol.Mathematical Complex Numbers. Complex numbers are those expressed as a+ib, where a, b are real numbers and I is a fictitious number called a "iota." I is equal to (-1). A complex number is, for instance, 2+3i, where 2 is a real number (Re) and 3i is an imaginary number (Im).Real and imaginary components are combined to form complex numbers, which have two elements. The foundation of more complex mathematics, like algebra, are complex numbers. They are applicable to a wide range of real-world situations, particularly in the fields of electronics and electromagnetism.[tex]& \frac{5+2 i}{-1+\sqrt{3} i} \times \frac{-1-\sqrt{3} i}{-1-\sqrt{3} i} \\[/tex]

Review the graph.
On a coordinate plane, a vector has origin (0, 0) and terminal point (3, 2).
What is the magnitude of the vector shown?
5
13
StartRoot 5 EndRoot
StartRoot 13 EndRoot
On a coordinate plane, a vector has origin (0, 0) and terminal point (3, 2). The magnitude of the vector is 5
How did we get the value?The magnitude of a vector can be calculated using the distance formula, which is the square root of the sum of the squares of the differences of the x and y components. In this case, the x component is 3 and the y component is 2, so the magnitude can be calculated as follows:
√(3^2 + 2^2) = √(9 + 4) = √(13) = 5

The value of function for f'(2) is 0.22.
What is the differentiation?The process of finding derivatives of a function is called differentiation in calculus. A derivative is the rate of change of a function with respect to another quantity.
Given that, f(x)= √(x+3) at the specific point x=2.
f'(2)= [tex]\lim_{h \to \ 0}[/tex]((f(2+h)-f(2))/h)
Find the derivative using the chain and power rules.
[tex]f(x)=(x+3)^{\frac{1}{2} }[/tex]
f'(x) = [tex]\frac{1}{2(x+3)^{\frac{1}{2} }}[/tex]
f'(2)= [tex]\frac{1}{2(2+3)^{\frac{1}{2} }}[/tex]
f'(2)= [tex]\frac{1}{2(2+3)^{\frac{1}{2} }}[/tex]
f'(2)= 1/2√5
f'(2)= 1/4.47
f'(2)= 0.22
Therefore, the value of function for f'(2) is 0.22.
