find the area of the circle r=14m use pi=3.14 and round your answer to the nearest hundredth
Answer:
The answer is 615 m²Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196
= 615.44
We have the final answer as
615 m² to the nearest whole numberHope this helps you

Step-by-step explanation:
(λ + 1) x² − 2x + (1 − λ) = 0
The discriminant is:
D = b² − 4ac
D = (-2)² − 4 (λ + 1) (1 − λ)
D = 4 − 4 (λ − λ² + 1 − λ)
D = 4 − 4 (1 − λ²)
D = 4 − 4 + 4λ²
D = 4λ²
Since D ≥ 0, the roots are real.
Using quadratic formula, the roots are:
x = [ -b ± √(b² − 4ac) ] / 2a
x = (2 ± 2λ) / (2(λ + 1))
x = (1 ± λ) / (λ + 1)
α, β = 1 or (1 − λ) / (λ + 1)
Therefore, the squares of the roots are:
α², β² = 1 or (1 − λ)² / (λ + 1)²
And the equation with these roots is:
(x − 1) (x − (1 − λ)² / (λ + 1)²) = 0
(x − 1) ((λ + 1)² x − (1 − λ)²) = 0
(λ + 1)² x² − (1 − λ)² x − (λ + 1)² x + (1 − λ)² = 0
(λ + 1)² x² − (1 − λ + λ + 1)² x + (1 − λ)² = 0
(λ + 1)² x² − 4x + (1 − λ)² = 0
Please help me solve this. :)

how do you solve 5y-2=10y-4
Answer:
y=2/5
Step-by-step explanation:
Using the power of inequalities, first, change the -2 to a positive by adding it to both sides of the equation. Second, get 10y and make it into a negative by subtracting it from both sides of the equation. Lastly, divide each side.
5y-2=10y-4
5y+2=10y+2
__________
5y=10y-2
-10y=-10y-2
__________
-5y=-2: Then Divide negative -5 in which your final answer should be y=2/5

A quilt piece is designed with four congruent triangles to form a rhombus so that one of the diagonals is equal to the side length of the rhombus. A rhombus with diagonals is shown. The diagonals form 4 triangles. All sides are 4 inches long. The distance from the top point to the middle point is 2 inches. The distance from the right point to the middle point is x. One interior angle is 30 degrees and another is a degrees. Which measures are true for the quilt piece? Select three options. a = 60° x = 3 in. The perimeter of the rhombus is 16 inches. The measure of the greater interior angle of the rhombus is 90°. The length of the longer diagonal is approximately 7 inches.
Answer:
1) a = 60°
3) The perimeter of the rhombus is 16 inches.
5) The length of the longer diagonal is approximately 7 inches.
Step-by-step explanation:
From the attached diagram, we begin to compare the options
1)a = 60°
From the question, we are told that:
One interior angle is 30 degrees and another is a degrees
The sum of angles in a rhombus = 360°
There are 4 angles in a rhombus and each angle should normally be equal to 90° hence,
a = 90° - 30°
a = 60°
2) x = 3 in.
Looking at the attached diagram,
We solve for x using Pythagoras Theorem
a² + b² = c²
a = 2 inches
b = x = ??
c = 4 inches
Hence,
2² + b² = 4²
b² = 4² - 2²
b² = 16 - 4
b² = 12
b = √12
b = 3.4641016151 inches
Option 2 is incorrect
3) The perimeter of the rhombus is 16 inches.
A rhombus is a quadrilateral with 4 sides that are equal to each other.
The perimeter of a Rhombus = 4a
Where a = Length of the side of a rhombus
From the above question, we are told that, the length of each side = 4 inches
Hence, perimeter = 4 × 4
= 16 inches.
Option 3 is correct
4)The measure of the greater interior angle of the rhombus is 90°.
The measure of the greater interior angle = 2 × a°
a° has already been solved for in option 1 as 60°
Hence,
Measure of the greater interior angle = 2 × 60°
= 120°
Option 4 is not correct.
5)The length of the longer diagonal is approximately 7 inches.
Since the Rhombus forms 4 equal triangles, it means the diagonals are the same.
Hence, the length of the longer diagonal
= 2 × 3.4641016151
= 6.9282032303 inches
Approximately = 7 inches.
Option 5 is correct.
Hence, the correct options are
1) a = 60°
3) The perimeter of the rhombus is 16 inches. The measure of the greater interior angle of the rhombus is 90°.
5) The length of the longer diagonal is approximately 7 inches.

which fraction is equivalent to -3/2
-3/2 is equivalent to -6/4 and 3/-2.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
Any fraction that can be obtained by multiplying both the numerator and denominator of -3/2 by the same nonzero number is equivalent to -3/2.
Now,
To find an equivalent fraction, we can choose any nonzero number and multiply both the numerator and denominator of -3/2 by that number.
For example:
Multiplying both the numerator and denominator by 2 gives:
(-3 × 2) / (2 × 2)
= -6/4
= -3/2
And,
Multiplying both the numerator and denominator by -1 gives.
= (-3 × -1) / (2 × -1)
= 3/-2
Therefore,
-3/2 is equivalent to -6/4 and 3/-2.

6. Given that AD= 61, CD= 61, and m< ABC= 48,
find m < CBD.
Answer:
m∠CBD=24
Step-by-step explanation:
The angle measure of m∠CBD = 24°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
AD= 61,
CD= 61,
and m∠ABC= 48°.
The diagram is given in the attached image.
Converse of Angle Bisector Theorem's
If a triangle's interior point is equally spaced from its two sides, that point will be on the angle bisector created by the two line segments.
That means,
angle measure of m∠CBD = 48/2 = 24°.
Therefore, m∠CBD = 24°.

–6x ≥ 72 solve (please help me because I'm not sure if my answer is correct or not)
My answer: x ≤ -12
Yes you are correct. You divide both sides by -6 to isolate x. Dividing both sides by a negative number will flip the inequality sign.
If you need to graph this, then you'll have a closed circle at -12 on the number line. Then you'll have shading to the left of this closed circle. The closed circle indicates "include this endpoint as part of the shaded solution set".

In a poll, 44% of the voters say they plan to reelect the mayor. The poll has a margin of error of ±3 percentage points. Use a model to write and solve an absolute value inequality to find the least and greatest percents of voters who plan to reelect the mayor. Response - correct |x−3|≤44 |x−3|≥44 |x−44|≤3 |x−44|≥3 Question 2 The least percent of voters who will vote for the new mayor is %. The greatest percent of voters who will vote for the new mayor is %.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Percentage of voters who plan to re-elect mayor = 44%
Margin of Error in measurement = ±3 % points
The absolute value inequality to find the lowest and greatest percent of points :
X = mid value
44% = estimated percentage
≤3 = error margin
Hence,
|mid value - estimate| ≤ error margin
|x−44|≤3
Hence,
-3 ≤ x - 44 ≤ +3
-3 + 44 ≤ x ≤ 3 + 44
41 ≤ x ≤ 47
Hence,
Least percentage point = 41
Greatesr percentage point = 47
