[tex]y=x^2+6x+10\\\\y=x^2+6x+9-9+10\\\\\bold{y=(x+3)^2+1}[/tex]
a = 1 > 0 ← it means the parabla opens up, so, the vertex is minimum

As per the power rule of exponents, the solution of 3 to the power of 3 is 27.
The term exponent in math is defined as a number shows how many times the number is multiplied by itself.
Here we have to solve 3 to the power of 3.
Here according to the Power Rule of Exponents then we have the rule as
=> aⁿ = a × a × a... (n times)
Therefore, the given expression is written as

Find the EXACT values of ALL SIX trigonometric functions of θ(sin, cos, tan, cot, sec, csc) from the information given. (a) cosθ=7/12, sinθ<0 (b) tanθ=4/3, θ in Quadrant III
Answers
(a) Since cosθ = 7/12 and sinθ < 0, we can find the other four trigonometric functions as follows:
sinθ = √(1 - cos²θ) = √(1 - (7/12)²) = √(1 - 49/144) = -√(95/144)
tanθ = sinθ / cosθ = (-√(95/144)) / (7/12) = -4√(5/18)
cotθ = 1 / tanθ = -1 / (-4√(5/18)) = 1/(4√(5/18))
secθ = 1 / cosθ = 1 / (7/12) = 12/7
cscθ = 1 / sinθ = -1 / (-√(95/144)) = √(95/144)
(b) Since tanθ = 4/3 and θ is in Quadrant III, we can find the other five trigonometric functions as follows:
cosθ = √(1 / (tan²θ + 1)) = √(1 / (16/9 + 1)) = √(9 / 25) = 3/5
sinθ = cosθ * tanθ = (3/5) * (4/3) = 4/5
cotθ = 1 / tanθ = 1 / (4/3) = 3/4
secθ = 1 / cosθ = 1 / (3/5) = 5/3
cscθ = 1 / sinθ = 1 / (4/5) = 5/4
What is trigonometric functions?Trigonometric functions are a set of functions that relate the angles of a right triangle to the ratios of the sides of the triangle. The six most commonly used trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
The sine function, represented by sin, gives the ratio of the side opposite the angle to the hypotenuse. The cosine function, represented by cos, gives the ratio of the adjacent side to the hypotenuse. The tangent function, represented by tan, gives the ratio of the opposite side to the adjacent side.
The cotangent function, represented by cot, gives the ratio of the adjacent side to the opposite side. The secant function, represented by sec, gives the ratio of the hypotenuse to the adjacent side, and the cosecant function, represented by csc, gives the ratio of the hypotenuse to the opposite side.

What is the log value of log2?
Answers
The log value of log2 is 1Log2 is defined as the logarithm base 2. This means that the logarithm of any number x is equal to the power to which the base 2 must be raised to produce x.
In other words, log2(x) = y, where 2^y = x.
Therefore, when x = 2, 2^y = 2. This means that the logarithm of 2 is equal to 1, since 2^1 = 2.
Therefore, the log value of log2 is 1.
Log2 is an important mathematical concept that is used to calculate the logarithm of a number. Logarithms are used in a variety of fields, including mathematics, physics, engineering, and computer science. Log2 is the logarithm with a base of 2, which means that the logarithm of any number x is equal to the power to which the base 2 must be raised to produce x. To calculate log2 of a number, the formula is log2(x) = y, where 2^y = x. This means that the logarithm of 2 is equal to 1, since 2^1 = 2. Therefore, the log value of log2 is 1. Log2 is often used to calculate logarithms of numbers that are not powers of 2, such as log2(3) = 1.5849. Log2 can also be used to calculate logarithms of numbers with decimals, such as log2(1.5) = 0.5849. Log2 can also be used to calculate exponents, such as 2^3 = 8.

Answer:
[tex]f(x) = 0.5(x+3)(x-1)[/tex]
Step-by-step explanation:
GIVEN :-
A quadratic function is represented by the graph in which :-
Vertex of the parabola = (-1 , -2)The function intersects x-axis at (-3 , 0) and (1 , 0)Y-intercept of the function = -1.5TO FIND :-
The quadratic functionGENERAL CONCEPT USED IN THIS QUESTION :-
A quadratic function has 2 forms :-
General form → f(x) = ax² + bx + cStandard form → f(x) = a(x - h)² + k [∵ where h = x-coordinate of the vertex of the function & k = y-coordinate of the vertex of the function.]SOLUTION :-
The quadratic function in the graph intersects x-axis at two points (-3 , 0) & (1 , 0). But there are infinite parabolas which also intersect the same two points. And those parabolas have their unique quadratic function.
Method 1 (System of equations method) -To find the unique quadratic function , you need to use three points on the
curve so that you can form 3 equations & solve them.
Using the General form of quadratic function , substitute the known values for x & y.
Let the three points be -
(-3 , 0)(1 , 0)(0 , -1.5)Substitute (-3 , 0) in general form of function -
[tex]0 = a(-3)^2 + b(-3) + c[/tex]
[tex]=> 9a-3b+c = 0[/tex] (eqn.1)
Substitute (1 , 0) in general form of function -
[tex]0 = a(1)^2 + b(1) + c[/tex]
[tex]=> a + b +c =0[/tex] (eqn.2)
Substitute (0 , -1.5) in general form of function -
[tex]-1.5 = a(0)^2 + b(0) + c[/tex]
[tex]=> c = -1.5[/tex]
Substitute c = -1.5 in -
1) eqn.1 → [tex]9a - 3b - 1.5 = 0[/tex]
[tex]=> 9a - 3b = 1.5[/tex]
[tex]=> 3(3a-b) = 1.5[/tex]
[tex]=> 3a-b = 0.5[/tex] (eqn.4)
2) eqn.2 → [tex]a+b-1.5=0[/tex]
[tex]=> a+b=1.5[/tex] (eqn.5)
Add eqn.4 & eqn.5 to get the value of 'a'.
[tex](3a-b)+(a+b) = 0.5+1.5[/tex]
[tex]=> 4a = 2[/tex]
[tex]=> a = \frac{2}{4} = \frac{1}{2} = 0.5[/tex]
Substitute a = 0.5 in eqn.5 -
[tex]0.5 + b = 1.5[/tex]
[tex]=> b = 1.5 - 0.5 = 1[/tex]
Now, rewrite the function in general form by putting the values of 'a' , 'b' & 'c'.
[tex]f(x) = (0.5)x^2 + (1)x - 1.5[/tex]
[tex]=> f(x) = 0.5(x^2 + 2x - 3)[/tex]
Factorise the quadratic polynomial.
[tex]=> f(x) = 0.5(x^2 + 3x - x - 3)[/tex]
[tex]=> f(x) = 0.5[x(x+3)-1(x+3)][/tex]
∴ [tex]f(x) = 0.5(x+3)(x-1)[/tex]
Method 2 (Vertex method) -Another way to find the function is by taking any point on the curve & using the vertex of the parabola ; substitute the known values for x , y , h & k in the Standard form of the function.
Let that point on the curve be (-3 , 0)
Vertex = (-1 , -2)
Substitute the values of x , y , h & k in Standard form of function.
[tex]0 = a[-3 - (-1)]^2 + (-2)[/tex]
[tex]=> 0 = 4a-2[/tex]
[tex]=> 4a = 2[/tex]
[tex]=> a = \frac{2}{4} = 0.5[/tex]
Now rewrite the Standard form of the function by putting the values of h , k & a.
[tex]f(x) = 0.5(x+1)^2-2[/tex]
Expand it.
[tex]=> f(x) = 0.5(x^2+2x+1)-2[/tex]
[tex]=> f(x) = 0.5x^2+x+0.5-2[/tex]
[tex]=>f(x) = 0.5x^2 + x- 1.5[/tex]
[tex]=>f(x) = 0.5(x^2 + 2x - 3)[/tex]
Factorising it will give the final answer.
∴ [tex]f(x) = 0.5(x+3)(x-1)[/tex]

What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
Angles ∠1 and ∠2 are linear and supplementary angles.
Angles ∠1 and ∠3 are vertically opposite angles.
