A coordinate plane is used to track the movement of a ship. The ship moved from (8, - 4) to (11, 11) on the coordinate plane. Which of the following translations describes the movement of the ship?
Answer:
the ship moved 4 coordinates away from the current position
Step-by-step explanation:
because 8-4 is 4
In the coordinate plane,
The ship moved 3 units right and 14 units up.
What is translation?A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Given:
A coordinate plane is used to track the movement of a ship.
The ship moved from (8, - 4) to (11, 11) on the coordinate plane.
The translation:
(11, 11) → (11 - 8, 11 +4) = (3, 14)
That means,
The ship moved 3 units right and 14 units up.
Therefore, hip moved 3 units right and 14 units up.

To estimate the percentage of a state's voters who support the current
governor for reelection, three newspapers each survey a simple random
sample of voters. Each paper calculates the percentage of voters in their
sample who support the governor and uses that as an estimate for the
population parameter. Here are the results:
• The Tribune, n = 600 voters sampled; sample estimate = 58%
• The Herald: n = 400 voters sampled; sample estimate = 54%
• The Times. n = 200 voters sampled; sample estimate = 68%
All else being equal, which newspaper's estimate is likely closest to the actual
percentage of voters who support the governor for reelection?
A. The Tribune, at 58%
B. The Times, at 68%
C. The Herald, at 54%

Find the perimeter of the trapezoid below:
NO CAP PLEASE, TAKE YOUR TIME!!!
Answer:
Perimeter = 82 units
Step-by-step explanation:
Find:
Perimeter
Computation:
Unknown height = 13 + x
So,
25² = x² + 24²
x = 7
So,
Unknown height = 13 + 7
Unknown height = 20 unit
Perimeter = 25 + 24 + 13 + 20
Perimeter = 82 units
write (3a^3)^2 without exponents
Answer:
9 x a x a x a x a x a x a
Step-by-step explanation:
[tex](3a^{3})^{2} = 9a^{6} \\[/tex] Here, we use the law of indices. Everything inside the bracket has to be squared, so 3^2 = 9 and (a^3)^2 = a^6 We use the rule of when one power is within a bracket and one outside, we multiply the two powers together instead of adding.
3^2 can be simplified to 9 as this is simply 3 x 3, but a^6 (this is still a value with an exponent) cannot be simplified so we break this down into the notation of a x a x a x a x a x a
Therefore 9 x a x a x a x a x a x a is the answer.
I hope this helps you!! ^-^
The expansion of (3a³)² without exponents will be 9 x a x a x a x a x a x a.
What is expansion?Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.
When a mathematical object is increased by a multiplier that is bigger in actual values than one, an expansion follows.
In another word, if you solve a factor by opening the bracket then you will go to get on some expanded term called expansion.
In mathematics, all real-life problems can be converted into equations which are sometimes in form of factors and we need to expand them to create solutions.
Given the expression,
(3a³)²
By the law of indices
(3a³)² = 3²(a³)²
(3a³)² = 9a⁶
But we cannot write it in exponent form
So,
9a⁶ = 9 × a x a x a x a x a x a.
Hence "The expansion of (3a³)² without exponents will be 9 x a x a x a x a x a x a".

The probability that comic book reader in a particular city prefers comics published by company A is 25%. The probability that comic book reader in the city's is male 70%
Complete question is;
The probability that a comic book reader in a particular city prefers comics published by Company A is 25%. The probability that a comic book reader in the city is male is 70%. If the probability of a comic book reader in the city being a male, given that the reader prefers Company A's comics, is 40%, what is the probability of the reader preferring Company A's comics, given that the reader is a male?
Answer:
0.14 or 14%
Step-by-step explanation:
We are told that the probability that the comic book readers prefers comics published by company A is 25%.
Thus; P(A) = 25% = 0.25
Also, we are told that the probability that comic book reader is male 70%.
Thus; P(M_r) = 70% = 0.7
We are also told that the probability of a comic book reader being a male, provided that the reader prefers Company A's comics, is 40%.
Thus; P(A|M_r) = 40% = 0.4
To find the probability of the reader preferring Company A's comics, provided that the reader is a male, we will apply baye's theorem.
Thus;
P(M_r|A) = [P(A|M_r) × P(A)]/P(M)
P(M_r|A) = (0.4 × 0.25)/0.7
P(M_r|A) ≈ 0.14

Answer:
x = 7[tex]\sqrt{2}[/tex] and y = 7
Step-by-step explanation:
Since this is 45 45 90 triangle, each leg is the same length so y = 7 too and x is always [tex]a\sqrt{2}[/tex] so x = 7[tex]\sqrt{2}[/tex]
The values of [tex]x[/tex] and [tex]y[/tex] are required.

[tex]y=7\ \text{units}[/tex]

Since, the two angles are equal the side opposite the angles will also be equal.
So,

Applying the Pythagoras theorem.
[tex]7^2+7^2=x^2\\\Rightarrow x=\sqrt{7^2+7^2}\\\Rightarrow x\approx 9.9[/tex]

You place two wooden support beams under a shelf, as shown. Find the value of x. (3x-13 ) (x- 3) x=
Answer:
x = 49Step-by-step explanation:
Fins the similar diagram attached;
The sum of the angles is 180 degree since they lie on the same straight line. Hence;
3x - 13 + x - 3 = 180
Collect the like terms;
3x+x -13 - 3 = 180
4x - 16 = 180
4x = 180 + 16
4x = 196
x = 196/4
x = 49
Hence the value of x is 49

The area of circle Z is 64Pi ft2. Circle Z is shown. Radius D has length r. R = StartRoot StartFraction Area Over pi EndFraction EndRoot What is the value of r? r = 4 ft r = 8 ft r = 16 ft r = 32 ft
Answer:
r = 8 ft
Step-by-step explanation:
Area of a circle => πr²
We are told in the question that:
The area of circle Z is 64Pi ft²
= 64π ft²
What is the value of r
We equate
πr² = 64 π
r² = 64 π/π
r² = 64
We square root both sides.
√r² = √64
r =>8 ft
The radius of the given circle Z is 8ft which was solved using the area of the circle
Data;
Area = 64π ft^2radius = rArea of a CircleThe formula of area of a circle is given as
[tex]A = \pi r^2[/tex]
Let's substitute the values and solve
[tex]A = 64\pi\\A = \pi r^2 \\64 \pi = \pi r^2\\[/tex]
divide through by π
[tex]64\pi = \pi r^2\\\\64 = r^2\\[/tex]
Let's take the square root of both sides
[tex]r^2 = 64\\r = \sqrt{64} \\r = 8ft[/tex]
The radius of the circle Z is 8ft
