Answers
we know that
cos 45°=√2/2
[he length of the hypotenuse]=11/cos 45-----------> 11/(√2/2)----> (11*2)/√2
=22/√2-------> 11√2 in
the answer Part A) is 11√2 in
Part B) What is the exact value of sin 45° ?
we know that
sin 45°=11/(11√2)-------> 1/√2---------> (1/√2)*(√2/√2)-----> √2/2
the answer part b) is √2/2
Part C)
What is the area of a regular hexagon with a side length of 4 m?
we know that
In case of a regular hexagon each of the six triangles that are formed by connecting its center with all six vertices is an equilateral triangle with a side equaled to 4 m.
The area of this hexagon is six times greater than the area of such a triangle
In an equilateral triangle with a side d
the altitude h can be calculate from the Pythagorean Theorem as
h²=d²−(d/2)²=(3/4)d²
Therefore,
h=d√3/2
Area of such a triangle is
A=d*h/2------------> d²*√3/4
From this the area of the regular hexagon with a side d is
S=6*A----------> d²3√3/2
for d=4 m
S=4²3√3/2------> 24√3 m²------------> 41.57 m²
the answer Part C) is 41.57 m²
Part D) In a 30-60-90 triangle, what is the length of the hypotenuse when the shorter leg is 5 cm?
[he length of the hypotenuse]=5/sin 30--------> 5/(1/2)---------> 10 cm
the answer part D) is 10 cm

Answers
Now to find how much she will need to save each month, we are going to divide the total cost of her college education by 48 months:

george has 2 times points of x
however x is 4 points less than sisters points which is 16 points
Then we subtract 4 from 16 = 12
12 is equal to x and george has twice of x
Therefore we first subtract 4 from 16 and then multiply it by 2, thats 12*2 = 24
therefore george has 24 points

Given cosx=1213 and sinx=513 .

Remember to show all of you work for credit!
Answers
Q1: Given sin(x+22)° = cos(2x−7)°
Using the concept of Right triangles and Trigonometric ratios, we can use a formula given as follows :-
If, sin(A) = cos(B). Then we must have A + B = 90 degrees.
We have sin(x+22)° = cos(2x−7)°
Then it must be true that (x+22)° + (2x−7)° = 90 degrees.
(x + 22) + (2x - 7) = 90
3x + 15 = 90
3x + 15 - 15 = 90 - 15
3x = 75
[tex] \frac{3x}{3} =\frac{75}{3} \\\\x = 25 \;degrees [/tex]
Hence, x = 25 degrees is the final answer.
Q2: Given cos(x) = 1213 and sin(x) = 513.
It says to find ratio of tan(x).
Using the concepts of Trigonometric ratios, We can the formula that relates all three functions i.e. sin(x), cos(x), and tan(x).
tan(x) = [tex] \frac{sin(x)}{cos(x)} [/tex]
We can plug the given values in the formula.
[tex] tan(x) = \frac{513}{1213} [/tex] is the final answer.

Answers
How to solve it:
Okay. So first off, lets subtract 424 from both sides. 424 - 424 cancels out. 1,000 - 424 is 576. That makes 9x = 576. Now, divide each side by 9 to isolate the c. 9x/9 cancels out. 576/9 is 64. There. x = 64. The team will need to score an average of 64 points in their remaining games in order to reach their goal.
What is the value of z in the equation 11 + z = 6?
66

1
Answers
Answer:
z = -5
Step-by-step explanation:
To find the value of z in the equation 11 + z = 6
we will simply subtract 11 from both-side of the equation. That is;
11 + z = 6
Subtract 11 from both-side of the equation
11 - 11 + z = 6 - 11
(On the left-hand side of the equation 11 will be subtracted from 11 which gives zero, thereby leaving us with just z while on the right-hand side of the equation 11 will be subtracted from 6 which will give negative 5)
z = -5
For the rational equation, x^2+5x+6/x+3=1 , what is a valid value of x?.
Answers
Answer:
B. -1
Step-by-step explanation:
We have the equation, [tex]\frac{x^{2}+5x+6}{x+3}=1[/tex].
Now, factorizing the polynomial [tex]x^{2}+5x+6[/tex], we get that the factors of the polynomial are (x+3) and (x+2).
So, we get,
[tex]\frac{x^{2}+5x+6}{x+3}=1[/tex]
i.e. [tex]\frac{(x+3)(x+2)}{x+3}=1[/tex]
i.e. x + 2 = 1
i.e. x = -1.
Hence, we get that the value of x is -1.

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
Total= $6,000
At local mall=$26,000
Now,
To find the total investment in education, we need to consider both the direct costs and the opportunity costs of going to college. The direct costs are the expenses that Lindsey has to pay for her education, such as tuition, fees, books, etc. The opportunity costs are the income that Lindsey could have earned if she did not go to college, such as working at the local mall.
The direct costs of going to college are $6,000 a year for four years, which is $24,000 in total.
The opportunity costs of going to college are $26,000 a year minus $8,000 a year for four years, which is $18,000 a year or $72,000 in total. This is because Lindsey could have earned $26,000 a year at the mall, but she is only earning $8,000 a year while going to school.
The total investment in education is the sum of the direct costs and the opportunity costs, which is
$24,000 + $72,000
= $96,000.
Therefore, by algebra the answer will be $96,000.
