What's the perimeter of (-9,8) (-9,16) and (-17,8)
Answer:
16 + sqrt(128)
Step-by-step explanation:
find the lengths of all 3 sides:
the side from (-9,8) to (-9,16) will be 16-8=8 (x stays constant)
The side from (-9,8) to (-17,8) is 8 (-9- (-17)=8)
The side from (-9,16) to (-17,8) will be found from the distance formula
d=sqrt((-17-9)^2 + (8-16)^2))
= sqrt(128)
So the perimeter will be these 3 numbers added together
P=sqrt(128) + 8 + 8
= 16 + sqrt(128)
which can simplify to:
= 16 + 4sqrt(8)
= 16 + 8sqrt(2) = 8+ sqrt(2)
Suppose the temperature inside a three dimensional ball is proportional to the square root of the distance from the center. Find a formula for the average temperature in the ball. What is the limit of the average temperature as the ball gets larger?
Answer:
The formula for the average temperature in the ball is [tex]\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}[/tex]. The limit of the average temperature for the ball does not exist.
Step-by-step explanation:
According to the statement, we have the following direct relationship:
[tex]T \propto \sqrt{r}[/tex]
[tex]T = k\cdot \sqrt{r}[/tex] (1)
Where:
[tex]T[/tex] - Temperature, measured in degrees Celsius.
[tex]r[/tex] - Distance from the center, measured in meters.
[tex]k[/tex] - Proportionality constant, measured in degrees Celsius per meter.
Under the assumption that ball is a continuous entity, we find that average temperature in the ball ([tex]\bar T[/tex]), measured in degrees Celsius, is represented by the following integral equation:
[tex]\bar T = \frac{1}{R}\cdot \int\limits^{R}_{0} {T(r)} \, dr[/tex] (2)
By applying (1) in (2), we find that:
[tex]\bar T = \frac{k}{R}\cdot \int\limits^{R}_{0} {\sqrt{r}} \, dr[/tex]
[tex]\bar T = \frac{2\cdot k}{3\cdot R}\cdot (R^{3/2})[/tex]
[tex]\bar T = \frac{2\cdot k\cdot R^{1/2}}{3}[/tex]
If the ball gets larger, then the limits associated to the average temperature diverges to the infinity as maximum exponent of the numerator of the rational function ([tex]n = \frac{1}{2}[/tex]) is greater than the maximum exponent of the denominator ([tex]n = 0[/tex]). Therefore, the limit of the average temperature for the ball does not exist.

apply the distributive property to factor out the greatest common factor 35 + 50= please answer soon
Solution:
Given that,
Apply the distributive property to factor out the greatest common factor
35 + 50
By distributive property,
a(b + c) = ab + ac
First find the greatest common factor of 35 and 50
The factors of 35 are: 1, 5, 7, 35
The factors of 50 are: 1, 2, 5, 10, 25, 50
Then the greatest common factor is 5
Thus, factor out 5 from given expression,
35+50= 5(7+10)
5(7+10)= 5×7+5×10
5(7+10)= 35+50
5(7+10)= 85
Thus distributive property is applied
Find the interest earned if you place $76.43 into an account that pays 21.5% simple interest and leave it in for 3 months.
Answer:

Answer:x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':
Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7
What’s the perimeter? And how do you find it?
Answer:
The perimeter would be 16
Step-by-step explanation:
you would do 5+5+3+3=16
Answer:
the answer is 16. trust me if you dont understand the explanation bc i am in 8th grade and have already done this.
plz mark brainliest.
Step-by-step explanation:
the way you find perimeter is by adding up all the sides.
the top and bottom are the same number so all you need is one of them to know what the other one is. they give you the top number and it is 3 so that means that the bottom number is 3.
the left and right side are also the same number. they give you the left sides number and it is 5 so that means that the right sides number is 5.
if the top number was lets say 10 then that would mean the bottom number would be 10. and the same goes for the sides.
so now you know that the right side number is 5 and the bottom is 3.
now all you have to do is 5 + 5 ( because there are two 5's) and 3 + 3 (because there are two 3's) so 5 + 5 is 10 and 3 + 3 is 6 now you add 6 + 10 and you get 16.
is 16% of 40 the same as 40% of 16
Answer:
no bc they r swapped and 40 is higher

In the expression " 5.3t - (20÷4) + 11" what part is a quotient? Describe its parts.
Answer:
(20 divided by 4) is the quotient
Step-by-step explanation:
In the expression the quotient part is 20÷4 and the quotient is 5.
The given expression is 5.3t - (20÷4) + 11.
What is a quotient?In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.
In the given expression 5.3t - (20÷4) + 11,
20÷4=5
So, 5.3t - 5 + 11
5.3t + 6
Hence, in the expression the quotient part is 20÷4 and the quotient is 5.

If the two lines y1 = -1/2x +5 and y2 = 2x + 5 were to be graphed, what would their intersection point represent?
A.Their intersection point is the only point where the same input into both functions yields different outputs.
B.Their intersection point is the only point where different inputs into both functions yield different outputs.
C. Their intersection point is the only point where different inputs into both functions yield the same output
D. Their intersection point is the only point where the same input into both functions yields the same output.
Answer:
D. Their intersection point is the only point where the same input into both functions yields the same output.
Step-by-step explanation:
The intersection point of 2 graphed lines represents the solution.
At this point, for both lines, there is the same x value (input) and the same y value (output) because both of the lines have that point in common.
So, if those 2 lines were to be graphed, the intersection point would represent the only point with the same input and output for both functions.
D is the correct answer.

Answer:
KEEP CALM AND DO THE MATH
Step-by-step explanation:
a) Our decoding strategy is to try to determine the mapping of code numbers to letters by looking at the range and/or frequency of the numbers. The minimum code value is 15, and the maximum is 41. We assume this means the value 15 corresponds to the letter A. Since the code is linear and the coefficient is 1, we assume this is a simple substitution code. We can find the letter number by subtracting 14 from the code number.

where alphabet[x] returns the x-th letter of the alphabet, and n is the code number. Subtracting 14 from the message numbers gives alphabet index number ...

Johannes needs to buy replacement team uniform and is looking at different prices. He has a budget of $300. He needs 18 pairs of pants and 12shirts. Let x represent the cost of each pairs of pants, and y represent the cost of each shirt. Which graph correctly shows the cost of the pants and shirts johannes can buy, if no tax is added?
Answer:
D.
Step-by-step explanation:
The graph that shows the cost of the pants and shirts Johannes can buy, is a linear graph
The budget is given as
[tex]\mathbf{Budget = 300}[/tex]
If x represents the cost of each pair of pants.
Then the amount spent on 18 pairs of pants is:
[tex]\mathbf{Pants = 18x}[/tex]
If y represents the cost of each shirt.
Then the amount spent on 12 shirts is:
[tex]\mathbf{Shirt= 12y}[/tex]
So, the equation is:
[tex]\mathbf{Shirts + Pants =Budget}[/tex]
Substitute known values
[tex]\mathbf{18x + 12y =300}[/tex]
Divide through by 6
[tex]\mathbf{3x + 2y =50}[/tex]
See attachment for the graph of [tex]\mathbf{3x + 2y =50}[/tex]
