shown. A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees. What is the value of x, rounded to the nearest degree? x ≈ ° According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Answer:
Part A
71°
Part B
The ladder is been used safely
Step-by-step explanation:
Part A
We solve the above question using Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = The distance between the house and the bottom of the ladder = 4 feet
Hypotenuse = Length of the ladder = 12 feet
x = Angle
Hence:
cos x = 4/12
cos x = 1/3
x = arc cos (1/3)
x = 70.528779366°
Approximately to the nearest degree
= 71°
Part B
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards. Is this ladder being used safely?
Angle x = 71°
Therefore, the ladder is been used safely

f(-2) when f(x)=25x-4
Answer:
25x4 - 2
Step-by-step explanation:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.

What are the measures of Angles d, e, and f? Show your work and explain your answers. (10 points)
Part A - Find the measure of angle d showing all work and reasoning. (3 points)
Part B - Find the measure of angle e showing all work and reasoning. (3 points)
Part C - Find the measure of angle f showing all work and reasoning. (3 points)
Part D - What does the box mean in the triangle with angles e and d? (1 point)
Answer:
Part A - Angle d is 29º
Part B - Angle e is 61º
Part C - Angle f is 95º
Part D - the box represents a 90º angle
Step-by-step explanation:
Angle d is 29º because of the vertical angles theorem
Angle e is 61º because if you take into account that it tells you one of the angles is 90º, you'll add d, which is 29º, to that in order to get 119. Then you'll subtract 119 from 180, as all the angles in a triangle must have a sum of 180º degrees. The result should be 61º
Although it looks rather acute, f should be 95 degrees because it's a supplementary angle with 85º, meaning you subtract 85 from 180
The box in the triangle is just a symbol indicating a 90º angle

Find p(-2) if p(x)=3x^3 -x^2 +2x-5. What does this tell you about the factors of p(x)
Answer:
[tex]\boxed{\textsf{ The value of the polynomial at p = (-2) is \textbf{ -37}.}}[/tex]
Step-by-step explanation:
A polynomial is given to us and we need to find its value at p = (-2) . The given polynomial is :-
[tex]\sf\implies p(x)= 3x^3 -x^2 +2x-5[/tex]
Also second part of the question says what does this tell about the factors of p(x) .
On putting p = (-2) :-
[tex]\sf \implies p(x)= 3x^3 -x^2 +2x-5 \\\\\sf\implies p(-2) = 3 (-2)^3-(-2)^2+2(-2)-5 \\\\\sf\implies p(-2)= 3\times (-8) -4 -4 -5 \\\\\sf\implies p(-2)=-24-4-4-5 \\\\\implies \boxed{ \pink{\sf p(-2)= (-37) }}[/tex]
Now this tells us that ( x + 2 ) is not a factor of the given polynomial. When we divide the given polynomial by (x + 2) then the remainder will be -37 .

$3 is what percent of $10?
The value of $3 is 30% of the number $10.
The percentage is a way to express a proportion or a fraction as a fraction of 100. It is commonly used to compare values or quantities relative to a whole or a total.
The term "percentage" comes from the Latin word "per centum," which means "per hundred." It implies that a percentage value represents a certain number out of 100 parts.
To calculate a percentage, you typically divide a part or a quantity by the whole or the total and then multiply the result by 100. The resulting value represents the percentage equivalent of the part or quantity.
The per cent value is calculated as,
[tex]x = \dfrac{3} {10} \times100\\x = 0.3\times100\\x = 30 \%[/tex]
Therefore, the percentage value is 30%.

Sam's mother is twice as old as Sam. In 12 years, Sam will be as old as his mother was 12 years ago. How old are Sam and his mother now?
Answer:
Sam is 24 years old and his mother is 48 years old.
Step-by-step explanation:
Equations
Let's call
x = Sam's current age
Since Sam's mother is twice as old as Sam:
2x = Sam's mother current age
x + 12 = Sam's age in 12 years
2x - 12 = Sam's mother age 12 years ago
These two last expressions are equal:
x + 12 = 2x - 12
Subtracting x and adding 12:
x = 24
2x = 48
Sam is 24 years old and his mother is 48 years old.
Sam, is 24 years old. His mom is 48 years old.
