No triangles possible
a ≈ 13.4, C ≈ 49.6, B ≈ 76.4
a ≈ 13.4, C ≈ 45.6, B ≈ 80.4
a ≈ 9, C ≈ 45.6, B ≈ 80.4
Answers
For finding side a, you can answer this easily by the Law of Cosines. The equation is
a2=b2 +c2 -2bccosA
a2 = 11^2 + 8^2 -2(11)(8)(cos54)
a2 = 81.55
a = √81.55
a = 9
Then, we use the Law of Sines to find angles B and C. The formula would be
a/sinA = b/sinB = c/sinC
9/sin54° = 11/sinB
B = 80.4°
9/sin54° = 8/sinC
C = 45.6°
The answer would be: a ≈ 9, C ≈ 45.6, B ≈ 80.4

Answers
Remember that angle measures in degrees and radians are based on the proportion of the angle to a complete circle, meaning a fraction of either 360° or 2π. Given that 360° = 2π, we can convert between degrees and radians. With this information in mind, set up a proportion and use it to convert an angle of 225° into radians.
Answers
And you want to compute 225 degrees in to radians, let's assume the final answer is x
Then, 360 / 2pi = 225 / x
Solve for it, you will get x= 5pi/4

Answers
x1+x2/2
so
-2+3/2
=1/2
=0.5
Answer: The required co-ordinates of the point are (0.5, 5.5).
Step-by-step explanation: We are given to find the co-ordinates of the point that splits CD in half if point C is located at (-2,4) and point D is located at (3,7).
The point that splits the line segment CD in half will be the mid-point of the segment CD.
We know that
the co-ordinates of the mid-point of a line segment with endpoints (a, b) and (c, d) are given by
[tex]\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]
Therefore, the co-ordinates of the given point that splits CD in half are given by
[tex]\left(\dfrac{-2+3}{2},\dfrac{4+7}{2}\right)=\left(\dfrac{1}{2},\dfrac{11}{2}\right)=(0.5,5.5).[/tex]
Thus, the required co-ordinates of the point are(0.5, 5.5).

Which expression is equivalent to (a^8)^4
Answers
The expression [tex](a^8)^4[/tex] is equivalent to [tex]a^{32}[/tex].
The correct option is [tex]a^{32}[/tex].
To simplify the expression [tex](a^8)^4[/tex], we need to apply the exponent rule for raising a power to a power. According to this rule, when we have an exponent raised to another exponent, we multiply the exponents together.
In this case, [tex](a^8)^4[/tex] can be simplified as [tex](a^8)^4[/tex], which equals [tex]a^{32}[/tex]. Therefore, the expression [tex](a^8)^4[/tex] is equivalent to [tex]a^{32}[/tex].
To understand why we multiply the exponents, think of it this way: [tex](a^8)^4[/tex] means we have the base a raised to the 8th power, and that whole expression is raised to the 4th power. When we multiply the exponents, 8 x 4, we get 32. This tells us that we have a multiplied by itself 32 times, which is represented by [tex]a^{32}[/tex].
Therefore, the correct answer is [tex]a^{32}[/tex].

Which represents the equation of the side that is parallel to side s?
Answers
So, the line parallel to s is q, which has these two points: (3,6) and (6,3)
There are different ways to get the line. For instance, this one:
y = a*x+b,
a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,
y = -x + b,
Now use any point, say (3,6) to get b:
6 = -3+b-> b = 9,
line is y = -x + 9,
It checks out in the other point: (6,3) --> 3 = -6+9 = 3. Good.
Other method could be:
y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.
Hope it helps!
The side that is parallel to side s is side q. The equation of side q is: y = -x + 9.
What is the Equation of a Line?We can represent the equation of a line as, y = mx + b, where m is the slope of the line and b is the y-intercept.
The side that is parallel to side s is q.
Slope (m) of q = change in y / change in x = (6 - 3) / (3 - 6) = 3/-3 = -1.
Substitute m = -1 and (3, 6) = (a, b) into y - b = m(x - a):
y - 6 = -1(x - 3)
y - 6 = -x + 3
y = -x + 3 + 6
y = -x + 9
Equation of the side that is parallel to side s is: y = -x + 9.

Answers
Answer:

Step-by-step explanation:
The volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Suppose the base of the pyramid has length = L units and width = W units, slant height = K units, and the height of the pyramid is of H units.
Then the volume of the pyramid will be
V = (L × B × H) / 3
V = (Base area x H) / 3
The volume of a pyramid varies jointly with the base area of the pyramid and its height.
The volume of one pyramid is 24 cubic inches when its base area is 24 square inches and its height is 3 inches.
Then the volume of a pyramid with a base area of 15 square inches and a height of 7 inches will be
V = (15 x 7) / 3
V = 35 cubic inches
Hence, the volume of a pyramid with a base area of 15 square inches and a height of 7 inches is 35 cubic inches.

Two points in the xy plane have cartesian coordinates (2.00, 24.00) m and (23.00, 3.00) m. determine (a) the distance between these points and (b) their polar coordinates
Answers
The distance between the two points is approximately 29.70 m. The polar coordinates of the points are approximately (24.20 m, 1.46 radians).
Explanation:To find the distance between two points in the Cartesian coordinate plane, we can use the distance formula.
The distance between the points (2.00, 24.00) m and (23.00, 3.00) m is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the values, we get:
d = sqrt((23.00 - 2.00)^2 + (3.00 - 24.00)^2)
d = sqrt(441 + 441)
d = sqrt(882)
d ≈ 29.70 m
The polar coordinates of a point (x, y) can be found using the formulas:
r = sqrt(x^2 + y^2)
p = atan2(y, x)
Plugging in the values, we get:
r = sqrt(2.00^2 + 24.00^2)
p = atan2(24.00, 2.00)
r ≈ 24.20 m
p ≈ 1.46 radians

Task 5—Polynomial Division and the Remainder Theorem
Create a quadratic polynomial function f(x) and a linear binomial in the form (x − a).
Part 1. Show all work using long division to divide your polynomial by the binomial.
Part 2. Show all work to evaluate f(a) using the function you created.
Part 3. Use complete sentences to explain how the remainder theorem is used to determine whether your linear binomial is a factor of your polynomial function
Answers
Part 1. In executing the long division method, you merely use the form like what were taught to in elementary:
Quotient
-------------------------
divisor| DIvidend
But in this case, we deal with polynomials instead of only numbers. The complete solution is
x + 1
-----------------------------
x+1 | x²+2x+1
-x²+x
------------------
0 + x+1
- x+1
-----------------
0
So, the answer is x+1.
Part 2. The quadratic equation is f(a) = x²+2x+1, where a is the constant in the binomial x-1. Thus, a=1. Substituting a to the x values, f(1) = (1)²+2(1)+1=0. The zero means that there is no remainder. Thus, (x+1) is a factor.
Part 3. The remainder theorem works similar to Part 2. If you substitute f(a) and the answer is a non-zero number, then that is the remainder when you divide the quadratic equation with the binomial. Only when the answer is zero that you can confirm that the linear binomial is a factor.
How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?
Answers
Answer:
[-8,2]
Step-by-step explanation:
We are given that the function f(x) is transformed to the function g(x), where,
[tex]f(x) =-5 \cos 2x[/tex] and [tex]g(x) =-5 \cos 2x-3[/tex].
Since, the range of [tex]\cos x[/tex] is [-1,1].
Thus, the range of [tex]a\cos bx[/tex] is {-a,a].
So, the range of [tex]f(x) =-5 \cos 2x[/tex] is [-5,5].
As, we are translating the function f(x) 3 units downward to get g(x).
The graph of the function is shifted 3 units down.
So, the range of g(x) will be [-5-3,5-3] = [-8,2].
Hence, the range of [tex]g(x) =-5 \cos 2x-3[/tex] is [-8,2].

The rational equation [tex]x^2 - 36 / (x+6)[/tex], when x is not -6, simplifies to x - 6. The correct answer is D.) x - 6.
Explanation:This is a Mathematics problem related to algebraic expressions and rational expressions. Given the equation [tex]x^2 - 36 / (x+6)[/tex], when x is not equal to -6, we can simplify this equation by factoring. Note that x^2 - 36 is a difference of two squares, which factors into (x-6)(x+6). So we now have [tex](x-6)(x+6) / (x+6).[/tex]
Since x is not -6, we can cancel out the (x+6)s, leaving us with x-6. Therefore, the answer is D.) x - 6. It's important to be careful with the conditions given in the problem, as they can affect the result.
