Pre-cal Problem, please, help is very much appreciated!
Answers
Let y be the length of the third side. By the Pythagorean theorem,
y² + x² = 3² = 9
so that
y = √(9 - x²)
(taking the positive root because one expects length to be positive)
Then by the definitions of sine, cosine, and tangent, we have
sin(θ) = x / 3 → θ = sin⁻¹(x / 3)
cos(θ) = √(9 - x²) / 3 → θ = cos⁻¹(√(9 - x²) / 3)
tan(θ) = x / √(9 - x²) → θ = tan⁻¹(x / √(9 - x²))

Answers
Answer:
b. 151m
Step-by-step explanation:
Step-by-step explanation:
That's the right answer on edge
The shadow of a 265m long building would be b. 151 m
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Ms. Kraus is 1.75 m tall. When her shadow is 1 m.
Let the shadow of a 265 m tall building be 'x' m.
Therefore by the ratio proportion method.
1.75 : 1 : : 265 : x.
1.75/1 = 265/x.
1.75x = 265.
x = 265/1.75.
x = 151.42 Or 151 m.

What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
We have a system of equations,
-3x+2y = -39 {equation 1}
and 5x+4y = 21 {equation 2}
To eliminate the variable y:
Multiply by 2 to the equation 1 and subtract to the equation 2,
5x + 6x + 4y - 4y = 99
11x = 99
x = 9
And y =-6
Therefore, the solution is x = 9 and y = -6.

What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
From the line, we can observe that the line is passing through (2, 0) and (0, 0.8).
Then the slope of the line will be
Slope = (0.8 – 0) / (0 – 2)
Slope = 0.4

1. Allison’s middle school team has designed t-shirts containing their team name and color. Allison and her friend Nicole have volunteered to call local stores to get an estimate on the total cost of purchasing t-shirts. Print-o-Rama charges a set-up fee, as well as a fixed amount for each shirt ordered. The total cost is shown below for the given number of shirts. Value T’s and More charges $8 per shirt. Which company should they use?
a. Does either pricing model represent a proportional relationship between the quantity of t-shirts and the total cost? Explain.
b. What is the constant of proportionality of Value T’s and More? What does it represent?
c. How much is Print-o-Rama’s set-up fee?
d. If you need to purchase 90 shirts, write a proposal to your teacher indicating which company the team should use. Be sure to support your choice. Determine the number of shirts that you need for your team.
Answers
Answer:
the numbers are missing here, so I looked for a similar question:
Print-O-Rama
# shirts total cost
10 $95
50 $375
a. Does either pricing model represent a proportional relationship between the quantity of t-shirts and the total cost? Explain.
Value T’s and More offers a proportional relationship since each t-shirt costs $8 regardless of the number of t-shirts
b. What is the constant of proportionality of Value T’s and More? What does it represent?
$8 per t-shirt
f(c) = $8t
the function of total cost = $8 times the number of t-shirts ordered
c. How much is Print-o-Rama’s set-up fee?
using the high-low method
variable cost = ($375 - $95) / /50 - 10) = $7 per t-shirt
fixed cost (set-up fee) = $375 - (50 x $7) = $25
d. If you need to purchase 90 shirts, write a proposal to your teacher indicating which company the team should use. Be sure to support your choice. Determine the number of shirts that you need for your team.
purchasing 90 t-shirts at Print-o-Rama costs = $25 + (90 x $7) = $655
purchasing 90 t-shirts at Value T’s and More costs = 90 x $8 = $720
you should purchase the t-shirts at Print-o-Rama since the cost is lower.

Find all real square roots of 25
Answers
Answer:
All real square roots of 25 is +5 and -5.
Step-by-step explanation:
When you square root something, you take the positive and negative of the number, so the square root of 25 would be 5 and -5.
When you do 5 times 5, you get 25 and when you do -5 times -5, you get 25 as well, this is why we do the negative as well.

How to find the closest integer less than and greater than the square root of a number?The function is strictly increasing function for x ≥ 0.
Assuming that all the values of x are ≥ 1, whenever there is increment in the value of 'x', the value of y increases too Perfect square are those integers whose square root is an integer. Let x-a be the closest perfect square less than x, and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).
When we do square root of something, we take the positive and negative of the number, so the square root of 25 would be 5 and -5.
When we do 5 times 5, we will get 25 and when we do -5 times -5, we will get 25 as well, this is why we do the negative as well.
Hence, all the real square roots of 25 are 5 and -5.

Yours,
Nathaniel
Step-by-step explanation:
The expression 2(3x + 4)(x - 1)(x-3) is equivalent to the expression 6x³ - 16x² - 14x + 24 option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
= 2(3x + 4)(x - 1)(x-3)
After the multiplication of the polynomial:
= 2(3x² + x - 4)(x - 3)
Again multiplication:
= 2(3x³ - 8x² - 7x + 12)
= 6x³ - 16x² - 14x + 24
Thus, the expression 2(3x + 4)(x - 1)(x-3) is equivalent to the expression 6x³ - 16x² - 14x + 24 option (A) is correct.
