Answer:
1)65.9
2)326.6
3)13.6
4)8.0
Step-by-step explanation:
The trick is always to look at the number after the first decimal for rounding to 1 decimal place, if its above 5, you round it up to the next decimal; eg. 13.45 = 13.5 because the 5 will round it up,and if value below 5, you round it down; eg. 12.34 = 12.3 because the 4 is below 5 and the nearest 10th decimal is 3.
Label the vertices and all the elements needed. find x. give reasons!
The value of x which is the missing angle of the triangles is; x = 30°
How to find the missing angles of a triangle?We know that Alternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent.
Thus, if we label the vertex with the unknown angle in the smaller triangle as A, then by the alternate angle theorem, we can say that;
∠A = 2x
Thus, from sum of angles in a triangle equals to 180°, we can say that;
x + 2x + 90 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
x = 90/3
x = 30°

What are the solutions of the equation x4 3x2 2 = 0? use u substitution to solve.
The solution of the equation is x=±i or x=±i√2.
Given that the equation is x⁴+3x²+2=0 and use u substitution method to solve.
We can rewrite our given equation as:
(x²)²+3x²+2=0
Let's assume that the (x²)=u.
The given equation is rewritten as u²+3u+2=0.
Factorize the quadratic equation by adding or subtracting two number that gives the sum of 3u and product 2u² as
u²+2u+u+2=0
u(u+2)+1(u+2)=0
Taking out (u+2) as common and get
(u+2)(u+1)=0
Compare each equation with 0 and get
u+2=0 or u+1=0
u=-2 or u=-1
Performing back substitution by substituting the values of u in x²
when u=-1 then x is
x²=-1
x=±√(-1)
As we know that √(-1)=i.
So, we get
x=±i
And when u=-2 then x is
x²=-2
x=±√(-2)
As we know that √(-1)=i.
So, substituting this, we get
x=±i√2
Hence, the solutions of the x⁴+3x²+2=0 is x=±i and x=±i√2.

how many ways are there to distribute 11 identical candies between 4 children such that each child receives at least 2 candies
There are 15 / 2 ways to distribute 11 identical candies between 4 children such that each child receives at least 2 candies.
If we give child A four candies and so we were left with 9 candies.
In addition, we will take child A away from consideration to ensure he received exactly four candies, and thus we were left with 9 dots and 2 slashes, separating the 4 remaining distinct children.
So the possible ways are: (11 + 4 / 2) = (15 / 2).

How do I decide if it’s a real solutions or extraneous solutions?
Step-by-step explanation:
So you can check for extraneous solutions by plugging in the 5 and -2 as x.
Plug 5 in as x
[tex]5=\sqrt{3(5)+10}\\5=\sqrt{15+10}\\5=\sqrt{25}\\5=5[/tex]
I'm not sure if this is exactly considered an extraneous solution, but I'm assuming it is, since technically the radical doesn't have a plus/minus in front of it, so it's the principle square root which means it only outputs the positive values. This would mean that the -2 wouldn't be a solution, since the principle square root doesn't output negative values, so it's a function, since if it outputted 2 values, then it wouldn't be a function by definition.
The following diagram represents all of the stages of a shrinking iceberg. The iceberg is circular, and when it started out, it had a radius of 100 feet. The iceberg shrank to a radius that was 75% of its original size every hour. Each circle in the drawing represents the size of the iceberg in each of the successive hours it was shrinking. Using this information, answer the questions having to do with the image:
a. Is this a geometric series or an arithmetic series? Explain why you chose this answer.
b. Describe the steps you would use to calculate the radius of the 6th circle.
c. Assuming this pattern continued forever, what would be the total length if you added all of the circles’ radii* together? Explain your answer.
A geometric progression is a sequence that involves a rate, causing a change in the subsequent values of the sequence with respect to the given rate.
The answers to the given question are as follows:
a. It is a geometric progression.
b. Radius of the 6th circle ≅ 23. 73 ft.
c. The total length, l, can be determined by: l = ∑0.75[tex]R_{i}[/tex], i = 1 to n.
Geometric progression involves a change in the subsequent values of a given sequence due to a rate. So considering the given question, the circular iceberg melts at a certain rate per hour. Thus its radius decreases at the given rate per hour.
a. Therefore it can be deduced that the question is on geometric progression.
b. To determine the radius of the 6th circle, the:
radius of the 1st circle = 100 ft
radius of the 2nd circle = 0.75 x 100
= 75 ft
radius of the t3rd circle = 0.75 x 75
= 56.25 ft
radius of the 4th circle = 0.75 x 56.25
= 42.1875 ft
radius of the 5th circle = 0.75 x 42.1875
= 31.640625 ft
radius of the 6th circle = 0.75 x 31.640625
= 23.73046875 ft
Thus the radius of the 6th circle is approximately 23. 73 ft.
c. Since the process is assumed to continue forever, let the number of hours required to be represented by n, and each radius of the iceberg be represented by R.
So then, we can say that the total length, l, of all the circles' radii is will be given by:
l = ∑0.75[tex]R_{i}[/tex], i = 1 to n

there are three brothers amir balu and caleb. Amirs age is half of calebs and balus age is 3/4 of calebs. In five years the sum of Amir's age and Balus age will be 16 more than Calebs age How old is each brother now.
The age of the brothers Caleb, Amir and Balu is 44 years, 22 years, and 33 years respectively.
What is Equation?An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.
Here, Let the age of the Caleb's be x years.
then age of Amir's be x/2 years.
also age of Balu's be 3x/4 years.
In 5 years,
Caleb's age = (x+5) years
Amir's age = (x/2 + 5) years
Balu's age = (3x/4 + 5) years
Now, According to question;
Amir's age + Balu's age = 16 + Caleb's age
(x/2 + 5) + (3x/4 +5) = 16 + (x + 5)
x/2 + 3x/4 - x = 16 + 5 - 5 - 5
(2x + 3x - 4x)/4 = 11
x/4 = 11
x = 4 X 11
x = 44
Now, Caleb's age = 44 years
Amir's age = 44/2 = 22 years
Balu's age = 3X44/4 = 33 years
Thus, the age of the brothers Caleb, Amir and Balu is 44 years, 22 years, and 33 years respectively.

Find the measure of the reference angle for an 11 radian
radian angle.
Answer:
about 1.56637 radians ≈ 89.746°
Step-by-step explanation:
The reference angle in radians can be found by the formula ...
ref angle = min(mod(θ, π), π -mod(θ, π))
Equivalently, it is ...
ref angle = min(ceiling(θ/π) -θ/π, θ/π -floor(θ/π))×π
ApplicationWhen we divide 11 radians by π, the result is about 3.501409. The fractional part of this quotient is more than 1/2, so the reference angle will be ...
ref angle = (1 -0.501409)π radians ≈ 1.56637 radians ≈ 89.746°

Consider the function.
Match each transformation of f(x) with its description.
stretches f(x) by a factor
of 4 away from the x-axis
shifts f(x) 4 units down
shifts f(x) 4 units right
compresses f(x) by a factor

The correct options are:
a) g(x) = 8*x - 6
b) g(x) = 2x - 10
c) g(x) = 2x - 14
d) g(x) = 8x - 24
How to identify each transformation?Here we have the function:
f(x) = 2x - 6
The proposed transformations are:
a) Stretch by a factor of 4 along the x-axis.
A horizontal stretch of scale factor k is written as:
g(x) = f(x*k).
Then, in this case, we have:
g(x) = 2(x*4) - 6 = 8*x - 6
b) Shift f(x) 4 units down.
A vertical shift of N units is written as:
g(x) = f(x) + N
A shift of 4 units down is written as:
g(x) = f(x) - 4 = 2x - 6 - 4 = 2x - 10
c) Shift f(x) 4 units right.
An horizontal shift of N units is written as:
g(x) = f(x + N).
For a shift of 4 units to the right, we write:
g(x) = f(x - 4) = 2(x - 4) - 6 = 2x - 8 - 6 = 2x - 14
d) A vertical compression of scale factor 1/4.
A vertical compression of scale factor K is written as:
g(x) = f(x)/K
In this case, we will have:
g(x) = f(x)/(1/4) = 4*f(x) = 4*(2x - 6) = 8x - 24

2r = 10
r = 10/2 = 5
r = MO

The interior angle of the 12-sided polygon is
[tex]\frac{180(12-2)}{12}=150^{\circ}[/tex]
So, if we consider the triangle with angle x, two of its angles are each [tex]30^{\circ}[/tex] since they are supplementary to the interior angle of the 12-sided polygon.
