Answer:
(10,8)
Step-by-step explanation:
The equation of a circle has the following form:
[tex](x-h)^2+(y-k)^2=r^2[/tex] where (h,k) is the center of a circle with radius r.
Our equation is:
[tex](x-10)^2+(y-8)^2=256[/tex]
The center is (10,8).
The center of the circle given by the equation (x−10)² + (y−8)² = 256 is (10, 8). This can be derived from the standard form of a circle's equation. Therefore, the coordinates are (10, 8).
The given equation of the circle is (x−10)² + (y−8)² = 256.
This equation is in the standard form of a circle's equation, (x−h)² + (y−k)² = r², where (h, k) represents the center and r is the radius.
In this case, the values of h and k can be directly identified from the equation: h = 10 and k = 8.
Therefore, the center of the circle is at the coordinates (10, 8).
Divide. Round to the nearest tenth if necessary.
65.2 ÷ 26
Please show procedure.
Final answer:
To divide 65.2 by 26, you perform the division to find that 26 goes into 65.2 exactly 2.5 times. Therefore, the answer, when rounded to the nearest tenth, is 2.5.
Explanation:
To divide 65.2 by 26, start with the division process. Place a decimal point directly above the decimal point in the dividend within the answer area. Since 26 does not go into 6, but goes into 65 twice, write 2 above the 5 in the dividend. Multiply 2 by 26 to get 52, and subtract this from 65, which leaves a remainder of 13. Bring down the 2 from the dividend to get 132.
Now, divide 26 into 132, which goes exactly 5 times. Multiplying 5 by 26 gives 130, subtract this from 132 to get a remainder of 2. Because we are left with no more numbers to bring down and our remainder is less than 26, we stop. The answer to 65.2 divided by 26 when rounded to the nearest tenth is 2.5.

The best way to start this is to plot the triangle. I use Desmos for this. See diagram below
The base is between (-6,8) and (3,8)
The 8s are the same for both points. The distance between -6 and 3 is abs(-6) + abs(3) = 9
That is the base of the triangle.
The height is between (-6,17) and (-6,8)
17 - 8 = 9
Notice I did not have to use the absolute values. Why not?

To find out how many days 1/3 of a packet of milk powder will last, divide 1/3 by 2 to get 1/6 of a day.
Explanation:To find out how many days 1/3 of a packet of milk powder will last, we can use the information given. Kate uses 2 packets of milk powder per day. This means in one day, she uses 2 packets. So, in order to calculate how many days 1/3 of a packet will last, we need to divide 1/3 by 2. This gives us 1/6.
Therefore, 1/3 of a packet will last 1/6 of a day.

1/3 of a packet of milk powder will last 1/6 of a day, or 4 hours, for Kate who uses 2 packets of milk powder per day.
If Kate uses 2 packets of milk powder per day, to determine how many days 1/3 of a packet of milk powder will last, you can perform a simple division. Since she uses 2 packets per day, you would divide the amount she has, 1/3 of a packet, by her daily usage, which is 2 packets. Therefore:
1/3 packets / (2 packets/day) = (1/3) / 2 days = 1/6 days
Thus, 1/3 of a packet of milk powder would last for 1/6 of a day. To determine the number of hours this represents, you can multiply 1/6 of a day by the number of hours in a day:
(1/6 day) times (24 hours/day) = 4 hours
Therefore, 1/3 of a packet of milk powder will last for 4 hours based on her current usage.

Decide whether the function is an exponential growth or exponential decay function, and find the constant percentage rate of growth or decay.
f(x) = 3.6 ⋅ 1.04x
Answer:
Exponential growth; percentage rate of growth is 4%.
Step-by-step explanation:
The function,
[tex]f(x)=3.6.(1.04)^x[/tex]
represents an exponential growth function because the growth factor is greater than 1.
The general form of an exponential growth function is,
[tex]y=a(1+r)^t=(a).(ar)^t[/tex], where 'r' is the percentage rate of growth.
If we compare the given equation with the standard form of the equation we can see that, we have,
[tex]f(x)=3.6(1+0.04)^x[/tex]
Therefore, the percentage rate of growth is = [tex]0.04 \times 100=4\%[/tex] .

Suppose we want to choose
2 letters, without replacement, from the
4 letters A, B, C, and D.
If order matters, then there are 12 ways to do this
If order does not matter, then there are 6 ways to do this
===========================================
We have 4 choices for the first slot and 3 choices for the next (we can't reuse a letter) so that's where 4*3 = 12 comes from
If order doesn't matter, then something like AB is the same as BA. So we are doubly counting each possible combo. To fix this, we divide by 2: 12/2 = 6
To be more formal, you can use nPr and nCr to get 12 and 6 respectively (use n = 4 and r = 2)
In combinatorics, you can choose 2 letters from 4 (A, B, C, D) without replacement in 6 ways, according to the 'combination' principle in probability.
Explanation:The subject of this question is combinatorics, a topic in Mathematics, particularly probability. You are asked to choose 2 letters without replacement from a set of 4 different letters {A, B, C, D}. To do this, we can use the formula for combinations, which is denoted as nCr, where n is the total number and r is the number being chosen. In this case, we can see it as 4C2.
To execute this, the formula is ‘n! / [r!(n-r)!]’ where '!' denotes factorial, meaning you multiply all natural number up to that number. Hence, 4C2 = 4! / [2!(4-2)!]. Factorial 4 (4!) = 4 * 3 * 2 *1 = 24. Factorial 2 (2!) is simply 2 * 1 = 2. Thus the calculation becomes 24 / [2*(2!)], simplifying to 24 / 4 which equals 6. So, there are 6 ways to choose 2 letters from 4 without replacement.

Paul took 42 mile bicycle trip. he bicycle 1 1/2 hours in the morning and two hours in the afternoon what is his average speed in miles per hour
Answer:
Paul's average speed for his bicycle trip is 12 miles/hour.
Step-by-step explanation:
Since Paul rode a total of 42 miles, we need to add up the total time it took him to complete all 42 miles. Since her rode 1.5 hours in the morning and another 2 hours in the afternoon, he rode a total of 3.5 hours. Speed is calculated by dividing distance by time. Since his total distance is 42 and his total time is 3.5, we divide 42 by 3.5 to get 12. Since our calculations included miles and hours, then our final answer would be 12 miles per hour.

It is worked out that 3 ladles full of soup each will feed 160 people.
The customers have complained in the past that the portions are too small.
The cook decides to give 5 ladles full of soup to each person.
How many people can now be fed soup?
Answer:if your still on it tell me
Step-by-step explanation:
By using the ratio and proportion method, it is calculated that 5 ladles of soup can feed 96 people.
Explanation:This problem can be solved using the ratio and proportion concept in Mathematics. Given that 3 ladles of soup feed 160 people, we can set up the ratio 3 ladles : 160 people. If the cook now provides 5 ladles, we need to know how many people this amount can feed. To find this, we cross-multiply in the ratio.
Calculating: (3 ladles x X people) = (160 people x 5 ladles), after simplifying we find that X = 96 people. This calculation suggests that the soup will now feed 96 people if each person is given 5 ladles of soup.

Find the recursive definition of the following sequence (Remember to define the first term t, the recursive rule to find tn,and the value n will start at.) 1, 6, 36, 216, 1296…..
The answer is composed of the following two equations
[tex]t_1 = 1[/tex] and [tex]t_n = 6*t_{n-1}[/tex]
both of these two equations combine to help form the full recursive definition
=================================================
Further explanation:
The terms are represented by the letter 't' for short. Since we have more than one term, and because we have only so many letters, this means we stick a number onto the 't' to help label multiple terms. We have t1 as the first term, t2 as the second, etc. The numbers are often show as subscripts like so [tex]t_1, t_2, t_3, \ldots[/tex]
The first term of the list of numbers is 1, so [tex]t_1 = 1[/tex] is what we start with to help set up the recursive definition.
Once we have this starting point, we use it to get to the next term which is 6. This value is 6 times the first value. Therefore, the recursive step is [tex]t_n = 6*t_{n-1}[/tex] basically saying "multiply the (n-1)st term by 6 to get the nth term. Translation: "whatever the current term is, multiply by 6 to get the next term".

Lucia tried to solve the system below. Lucia’s Work. What error did Lucia make? When Lucia solved for the value of x, she subtracted 2y from both sides. When Lucia solved for the value of y, she treated –2y as 2y. When Lucia solved for the value of x, she added 18 to both sides. When Lucia solved for the value of x, she treated –2(–9) as 18 instead of –18.
Final answer:
The question hints at possible arithmetic or sign operation errors Lucia made while solving a system of equations. Pinpointing her exact mistake involves understanding common errors like incorrect handling of negative numbers or arithmetic operations.
Explanation:
The question involves identifying the mistake Lucia made when solving a system of equations. When solving for the value of x, there are various potential errors one could make, such as incorrect addition, subtraction, or misinterpretation of the operation sign. For instance, treating − 2( − 9) as 18 instead of − 18 is a common mistake due to misunderstanding how to handle double negatives in algebra. Similarly, when solving for the value of y, mistaking − 2y for 2y shifts the equation's balance, leading to incorrect solutions.
Lucia's error could stem from a few different places described in the question, but without the specific steps Lucia took, it's challenging to pinpoint the exact mistake. However, common errors to watch out for when solving for x and y in systems of equations include incorrect operations with negative numbers, improper handling of variables, or erroneous arithmetic operations.
Correctly solving a system of equations requires careful attention to each algebraic step, ensuring that operations on both sides of an equation are correctly applied and that signs are properly managed. Seeking to correct mistakes like treating negative signs improperly or misapplying arithmetic operations is essential for accurate solutions.

Transformation that produces an image that is the same shape but different size?
Answer:
Transformation that produces an image that is the same shape but different size is known as Dilation.
Step-by-step explanation:
There are many types of translations.
1. Rotation
2. Reflection
3. Translation
4. Dilation
We know that rotation, reflection and translation are rigid transformation. It means these transformation can not effect the size of the preimage.
Dilation represents the enlargement and compression of the figure according to the scale factor k.
If |k|>1, then it represent enlargement and if |k|<1, then it represent compression.
Therefore the transformation that produces an image that is the same shape but different size is known as Dilation.
