tan Z = 12/5cos Z = 5 / 13How to determine the correct trigonometry ratioInformation given in the question include
In triangle XYZ
angle Y
sin X = 5 / 13
A right angle triangle has three sides namely Adjacent, Opposite and Hypotenuse
from Sin X = opposite = Hypotenuse = 5 / 13
we have that
opposite = 5
Hypotenuse = 13
Using Pythagoras theorem
Hypotenuse^2 = opposite^2 + Adjacent^2
13^2 = 5^2 + Adjacent62
Adjacent = √(169 - 25)
Adjacent = 12
The correct options are tan Z = 12/5 and cos Z = 5 / 13

Which rule must be used to find the number of positive integers less than 1000 that are divisible by 7?.
Answers
The number of positive integers smaller than 1000 that are divisible by 7 must be determined using the rule of arithmetic progression.
There are 142 positive integers that are divisible by 7 that are less than 1000.
The positive numbers below 1000 that can be divided by seven include
7, 14, 21, 28,..........994.
The final number under 1000 that is divisible by 7 is 994.
An arithmetic progression's common form is [tex]T_{n} = a + (n-1)d[/tex]
where d is the common difference, n is the number of terms, and a is the first term.
We've :
a is 7 and d is 7.
When we generalize these values, we get at:
[tex]T_{n} = a + (n-1)d\\994 = 7 + (n-1)7\\994 -7 = 7n - 7\\994 = 7n \\n =\frac{994}{7} =142[/tex]
There are hence 142 positive integers below 1000 that are divisible by 7.

Answers
2 Answers:
Choice C and choice E
======================================================
Explanation:
Choice A is ruled out because of the phrasing "rises and falls". A linear function can't do both rising and falling. You must only pick one direction to aim for. Choice B is ruled out for similar reasoning. A parabola is likely a better option for choice B.
Choice C is linear assuming the car stays at 55 mph. Recall that distance = rate*time. In this case, the equation is y = 55x where x is the number of hours and y is the distance traveled in miles. As an example, x = 10 hours leads to y = 550 miles traveled.
Choice D isn't linear. The increase of 2 doesn't match with the increase of 1. Linear functions must have the same amount of increase over the same time gap.
Choice E is linear and the equation is y = 2x, where x is the number of years and y is the number of movies made total. For example, at year x = 10, the director has made y = 2x = 2*10 = 20 movies total.

Answers
The 3 numbers are 17/4, and the number is equal to or greater than 8, and 7 respectively. We can solve the equation using a linear equation in one variable.
What is a linear equation?A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.
1) Given that
five times the difference between a number and two is seven more than that number
Hence, by forming an equation we get
5(n-2) = n+7
5n -10 = n+7
4n = 17
n = 17/4
2)Given that
twice a number decreased by four is greater than ten, what numbers satisfy this condition
Hence, by forming an equation we get
2n -4 > 10
2n -4+4 > 10+4
2n > 14
2n / 2 > 14/2
n > 7
hence, a number greater than 7 will satisfy the equation.
3) Given that
twice a number decreased by two is equivalent to that number increased by five.
2n-2 =n +5
n = 7
Hence the number is 7

a) The angles associated with the cosine function are θ₁ = 45°, θ₂ = 315° and θ₃ = 405°.
b) The secant function of 585° is equal to - √2.
How to determine the value of a trigonometric function associated with a given angle
Graphically speaking, trigonometric functions are relations between two sides of a right triangles related to an angle. There are six trigonometric functions: (i) Two fundamentals (sine, cosine), (ii) Four derivates (tangent, cotangent, secant, cosecant). In the first part, we need to find all the possible angles such that the following trigonometric function is met:
cos θ = √2 / 2
The angles are located in the first and fourth quadrants, respectively. The solutions are θ₁ = 45°, θ₂ = 315° and θ₃ = 405°, respectively.
Now, we need to determine the secant function of 585°. Since the secant function has period of 360°, then we must find an angle coterminal to 585° that is between 0° and 360°:
θ' = 585° - 360°
θ' = 225°
And the trigonometric function is rewritten in terms of fundamental trigonometric functions:
x = 1 / cos θ'
x = 1 / cos 225°
x = 1 / (- √2 / 2)
x = - 2 / √2
x = - √2
The secant function of 585° is equal to - √2.

The local bakery sells both strawberry and chocolate cupcakes. The ratio to strawberry cupcakes to chocolate cupcakes is 8:4. If they baked 240 strawberry cupcakes How many chocolate cupcakes did they bake?
Answers
The local bakery baked 120 chocolate cupcakes
The ratio of the strawberry cupcake to chocolate cupcake = 8:4
Number of strawberry cupcakes baked = 240
Ratios: Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other.
Let x represent the total number of cupcakes baked by the bakery
The Sum of the ratio is 8+4 = 12
So, the fraction of strawberry cupcakes baked = 8/12
The total number of cupcakes:
= 8/12 of x =240
8/12x = 240
x = 240*12/8
= 360
So, the number of chocolate cupcakes = 4/12 of 360

A linear equation is a mathematical expression that may be written as x 1+ldots +a n+x n+b=0, where x 1, ldots, and x n are the variables and displaystyle b, a 1, ldots, and a n are the coefficients, which are frequently real integers.
Simplifying
4x + -2y to 40
Solving
4x + -2y = 40
fixing the 'x' variable.
x should be moved to the left of all terms, and the right of all other terms.
To each side of the equation, add "2y."
4x + -2y + 2y = 40 + 2y
combining similar terms
-2y + 2y = 0
4x + 0 = 40 + 2y
4x = 40 + 2y
Multiply each side by "4".
x = 10 + 0.5y
