Find the area of each figure one of the sides are 8.3cm it’s a square btw
Answer:
68.89 cm
Step-by-step explanation:
8.3 X 8.3 would equal 68.89 cm. We can see that one side is 8.3 cm, and the other sides don't say their sides, so the only number we will use for multiplying is 8.3, and all sides of the square will be 8.3. The equation is L X W, where L is the length, and W is the width. Since 8.3 is on all four sides, it will also be the length and the width on the equation. As a result, 68.89 cm would be the final answer.
Answer:
I don't real know if this is right, but I think its this:
68.89 cm2 is the area.
What two numbers add up to -2 and multiple to 10
There are no two Real numbers that add up to -2 and multiply to 10.
The numbers that add up to -2 and multiply to 10, we can use algebraic methods. Let's denote the two numbers as x and y. Based on the given conditions, we can set up two equations:
Equation 1: x + y = -2
Equation 2: x * y = 10
To solve this system of equations, we can use substitution or elimination methods. Let's solve it using the substitution method:
1. Solve Equation 1 for x:
x = -2 - y
2. Substitute the value of x in Equation 2:
(-2 - y) * y = 10
3. Simplify the equation:
-2y - y^2 = 10
4. Rearrange the equation to standard form:
y^2 + 2y + 10 = 0
5. Since the equation is a quadratic equation, we can apply the quadratic formula:
y = (-b ± √(b^2 - 4ac)) / (2a)
In this case, a = 1, b = 2, and c = 10.
6. Calculate the discriminant: b^2 - 4ac:
2^2 - 4(1)(10) = 4 - 40 = -36
7. Since the discriminant is negative, the quadratic equation does not have real solutions. Therefore, there are no real numbers that satisfy both conditions of adding up to -2 and multiplying to 10.
In conclusion, there are no two real numbers that add up to -2 and multiply to 10.

According to your graphing calculator, what is the approximate solution to the trigonometric inequality cos(0.65x)>.44 over the interval 0
Answer:
the solution to the trigonometric inequality cos(0.65x) > 0.44 over the interval 0 ≤ x < 4.834.
Step-by-step explanation:
The given inequality is:
cos(0.65x) > 0.44
To solve this inequality, we need to isolate the variable x.
First, let's take the inverse cosine (arccos) of both sides to remove the cosine function:
arccos(cos(0.65x)) > arccos(0.44)
Since the range of the inverse cosine function is limited to [0, π], we can rewrite the inequality as:
0 ≤ 0.65x < π
Now, let's solve for x by dividing each part of the inequality by 0.65:
0/0.65 ≤ x < π/0.65
Simplifying, we have:
0 ≤ x < π/0.65
Now, let's calculate the approximate value of π/0.65 to determine the interval for x:
π/0.65 ≈ 4.834

Kenneth is creating a chart to compare and contrast the different transformations of objects. He wants to show similarities and differences between translations, rotations, and reflections. In his chart, four statements are given. Which statements are true for a translation? Group of answer choices The distances between points on the polygon are preserved by the transformation. The orientation of points on the polygon is preserved by the transformation. The distance between corresponding points in the image and pre-image is constant. The angle measures between sides on the polygon are preserved by the transformation.
The statements that are true for a translation are:
The distances between points on the polygon are preserved by the transformation.
The distance between corresponding points in the image and pre-image is constant.
These statements are true for a translation because when an object is translated, it is shifted a certain distance in a certain direction. This means that the distances between points on the polygon remain the same and the distance between the corresponding points in the image and pre-image is constant.
Translation is the process of converting written, spoken, or visual information from one language into another. It is a complex process involving both linguistic knowledge and cultural understanding. Professional translators use a range of techniques to accurately convey the meaning of a text, including knowledge of grammar, syntax, and idiomatic expressions. Translators also take into account the cultural context of the text, ensuring that the translation reflects the same cultural references and nuances as the original. Translation can also refer to the conversion of DNA sequences from one form to another, such as from RNA to protein.

Considering only the values of θ for which the expression is defined, which of the following is equivalent to the expression below?
cos(−θ)⋅tan(−θ)⋅cscθ
Select the correct answer below:
−sinθ
1
sinθ
−1
The cos(θ) term cancels out and we are left with -1. Therefore, the equivalent expression is -1.
We can start by using the trigonometric identities:
cos(-θ) = cos(θ)
tan(-θ) = -tan(θ)
csc(θ) = 1/sin(θ)
Substituting these identities into the original expression, we get:
cos(θ) * (-tan(θ)) * (1/sin(θ))
Simplifying this expression, we can cancel out the cos(θ) and the sin(θ) terms:
-1 * cos(θ) * (1/(cos(θ))) The cos(θ) term cancels out and we are left with -1. Therefore, the equivalent expression is -1.
In other words, the original expression simplifies to -1 for all values of θ where it is defined (i.e. θ ≠ (2n + 1)π/2, where n is an integer). This means that as θ varies, the value of the expression will always be -1 when it is defined. Trigonometric identities are mathematical equations that involve trigonometric functions and are true for every possible value of the variables involved. There are various types of trigonometric identities, including:
Pythagorean Identities:
\(sin^2a + cos^2a= 1\\tan^2a + 1 = sec^2a\\1 + cot^2a = csc^2a\)
Angle Sum and Difference Identities:
sin(α±β) = sin α cos β ± cos α sin β
cos(α±β) = cos α cos β ∓ sin α sin β
tan(α±β) = (tan α ± tan β) / (1 ∓ tan α tan β)
Double Angle Identities:
sin 2θ = 2 sin θ cos θ
cos 2θ =\(cos^2\)θ - \(sin^2\)θ = 2 \(cos^2\)θ - 1 = 1 - 2\(sin^2\)θ
tan 2θ = (2 tan θ) / (1 - \(tan^2\)θ)
Half Angle Identities:
sin (θ/2) = ± √[(1 - cos θ) / 2]
cos (θ/2) = ± √[(1 + cos θ) / 2]
tan (θ/2) = ± √[(1 - cos θ) / (1 + cos θ)]
Product-to-Sum Identities:
sin α sin β = (1/2) [cos (α-β) - cos (α+β)]
cos α cos β = (1/2) [cos (α-β) + cos (α+β)]
sin α cos β = (1/2) [sin (α+β) + sin (α-β)]
Sum-to-Product Identities:
sin α + sin β = 2 sin [(α+β)/2] cos [(α-β)/2]
sin α - sin β = 2 cos [(α+β)/2] sin [(α-β)/2]
cos α + cos β = 2 cos [(α+β)/2] cos [(α-β)/2]

What transformations can be applied to Circle 1 to prove that the circles are similar?
Enter your answers in the boxes.
The circles are similar because you can translate Circle 1 using the transformation rule ( , ) and then dilate it using a scale factor of .
The circles are similar because you can translate Circle 1 using the transformation rule (9, 5) and then dilate it using a scale factor of 2.
To prove that Circle 1 and Circle 2 are similar, we need to identify the transformations that can be applied to Circle 1 to obtain Circle 2.
First, let's consider the translation of Circle 1. The translation rule is given by (a, b), where a represents the horizontal shift and b represents the vertical shift.
In this case, to translate Circle 1 to align with Circle 2, we need to shift it 9 units to the right and 5 units up. Therefore, the translation rule for Circle 1 is (9, 5).
Next, let's consider the dilation. A dilation is a transformation that changes the size of the figure but preserves its shape. The scale factor, denoted by k, determines the amount of scaling. In this case, Circle 1 needs to be dilated to match the size of Circle 2.
The scale factor can be determined by comparing the radii of the two circles. The radius of Circle 1 is 3 centimeters, while the radius of Circle 2 is 6 centimeters. The scale factor is obtained by dividing the radius of Circle 2 by the radius of Circle 1: 6/3 = 2.
Therefore, the transformation applied to Circle 1 to prove that the circles are similar is a translation by (9, 5) followed by a dilation with a scale factor of 2.

Two parents who are each known to be carriers of an autosomal recessive allele have four children. None of the children has the recessive condition.What is the probability that one or more of the children is a carrier of the recessive allele? Hint: The probability that one or more of the children is a carrier is the same as the sum of all probabilities minus the probability that none of the children is a carrier. The answer is 0.988. I know the answer but do not know the explanation. So, if someone could walk me through it, I would greatly appreciate it.
The probability that one or more of the children is a carrier of the recessive allele is 0.988.
The probability that one or more of the children is a carrier of the recessive allele can be calculated using the binomial theorem. The binomial theorem states that the probability of a success in a given trial is the sum of all probabilities of success minus the probability of none of the successes.
For the given scenario, we can assume that the probability of each child being a carrier is 0.25 (since each parent is known to be a carrier). The probability of one or more of the children being a carrier is then\((1-0.25^4) = 0.988.\)
To calculate this, we first calculate the probability of none of the children being a carrier, which is \((1-0.25)^4 = 0.316\). We then subtract this from 1 to get the probability of one or more of the children being a carrier:\((1-0.25)^4 = 0.316\)
Therefore, the probability that one or more of the children is a carrier of the recessive allele is 0.988.
