Using PEMDAS to resolve the trigonometric identity which involves trigonometric function, the value of tan A + tan B is 416 / 87
What is Trigonometric IdentityA trigonometric identity is an equation that is true for any value of the variables involved. These identities are useful in solving problems involving trigonometric functions. Examples include the Pythagorean identity, the sine and cosine addition formulas, and the double angle formulas.
In the given problem, we have a compound angle problem and we can solve it as;
tan A + tan B = [(tan A + tan B)] / [1 - tan A * tan B]
tan A = 7/24tan B = 15 / 8Substituting the values into the expression and solve;
tan A + tan B = [(7/24 + 15/8)] /[1 - (7/24)(15/8)]
Applying the rules of PEMDAS;
tan A + tan B = (13 / 6) / (29 / 64)
tan A + tan B = 416/87

There are a total of 32 books and calculators on a table. The ratio of the number of books to the
number of calculators is 5: 3. How many calculators are on the table?
A. 3
B. 12
C. 20
D. 24
Answer:
B. 12
Step-by-step explanation:
Your ratio of 5:3 means that the ratio includes 8 objects (5+3). If you multiply the whole ratio by 4, then you have 32 objects on your table. Multiplying your ratio by 4 gives you 5*4 : 3*4 which is 20:12. and since 20 is your amount of books and 12 is your amount of calculators, you have 12 calculators on your table.
Can someone help with this? Please be right
Answer:
See attached
Step-by-step explanation:
You want various combinations of the functions g(a) = -3a+1 and h(a) = 3a³ +4a.
g/hThe functions have no common factors, so their ratio leaves the function expressions unchanged:
[tex]\dfrac{g(a)}{h(a)}=\boxed{\dfrac{-3a+1}{3a^3+4a}}[/tex]
h+gThe like terms are combined when the functions are added.
[tex]h(a)+g(a)=(3a^3+4a)+(-3a+1)=3a^3+(4-3)a+1\\\\=\boxed{3a^3+a+1}[/tex]
g-hSimilarly, the like terms are combined when the functions are subtracted.
[tex]g(a)-h(a)=(-3a+1)-(3a^3+4a)=-3a^3+(-3-4)a+1\\\\=\boxed{-3a^3-7a+1}[/tex]
g·hThe product is found the way products are usually found. Each term of one of the factors is multiplied by each term of the other factor, and these products are summed. You can think of it as repeated application of the distributive property.
[tex]g(a)\cdot h(a)=(-3a+1)(3a^3+4a)=-3a(3a^3+4a)+1(3a^3+4a)\\\\=-9a^4-12a^2+3a^3+4a\\\\=\boxed{-9a^4+3a^3-12a^2+4a}[/tex]

. How many four letter patterns can be formed using the letters A, B, and C if letters may be repeated?
Answer:
24 patterns
Step-by-step explanation:
Given that four lettered patterns are to be formed using the three alphabets. Since letters may be repeated, then;
4[tex]P_{3}[/tex] = [tex]\frac{4!}{(4 - 3)!}[/tex]
= [tex]\frac{4 x 3 x 2!}{1!}[/tex]
= 4 x 3 x 2
= 24
4[tex]P_{3}[/tex] = 24
Therefore, 24 four letter patterns can be formed when the given letters are repeated.

1. What property could you use to show that these two triangles are congruent? QRP XWY
The property that could be used to determine that the triangles are congruent is the SSA congruent theorem
How to determine the congruent propertyFrom the question, we have the following parameters that can be used in our computation:
Triangles = QRP and XWY
On the triangles, we can see that:
Two corresponding sides on both triangles are marked with I and IIThe triangles have a pair of corresponding anglesThis means that we make use of the SSA congruent theorem
The SSA congruent theorem implies that if two sides and an angle not included between them are respectively equal to two sides and an angle of the other than the two triangles are equal.
In this case, we have
Congruent sides: RQ and HG & PR and HF
Congruent angles: Angles Q and G
Hence, the additional information on the congruency of the triangles is the SSA theorem

calculate the area of a circle with a diameter of 0, 8m
Answer:
50.24=4squared times pie
Step-by-step explanation:
Answer:
The area of a circle with a diameter of 0.8 meters is approximately 0.50 [tex]m^2[/tex].
Step-by-step explanation:
Since the diameter of the circle is 0.8 meters, that means the radius of the circle would be 0.4 meters. The area of a circle can be found by the formula [tex]\pi r^2[/tex], where [tex]r[/tex] represents the radius of the circle. In this case, the area would be [tex]0.4^2*\pi[/tex] = [tex]0.16 * \pi[/tex] ≈ 0.50 [tex]m^2[/tex].

The points obtained by students of a class in a test are normally distributed with a mean of 60 points and a standard
deviation of 5 points.
About what percent of students have scored less than 45 points?
0.15
2.5
15.5
34
Answer:
0.135%
Step-by-step explanation:
Given :
Mean, m = 60
Standard deviation, σ = 5
x = 45
The Zscore = (x - m) / σ
Z = (45 - 60) / 5 = - 15 / 5 = - 3
P(Z < - 3) = 0.0013499
0.0013499 * 100%
= 0.13499%
Only about 0.135% scored below 45
Evaluate the expressions 56 with a variable of -1
Answer:
The expression 56 with a variable of -1 is not well defined. The term 56 is a constant number, and the variable of -1 is also a constant. Therefore there is nothing to evaluate.
Step-by-step explanation:
If you want to evaluate the expression 56*(-1) it would give -56 as output because -1 is a scalar and multiplying with a scalar will change the sign of the constant 56 but it won't change its value.
In other words, to evaluate an expression, it needs to have a mathematical operation or function, operands, and/or variables that can be replaced with values or expressions. Without any operation, there's nothing to evaluate.
