Answer:
Step-by-step explanation:
let coordinates of D are (x,y)
mid point of AC=midpoint of BD
so{ (-3+4)/2,(1+6)/2}={(x+(-1))/2,(y+4)/2}
(1/2,7/2)={(x-1)/2,(y+4)/2}
(x-1)/2=1/2
x-1=1
x=1+1=2
(y+4)/2=7/2
y+4=7
y=7-4=3
so D is (2,3)

is it possible to construct a triangle with the given lengths? 16, 37, 53
Answer:
No, you can not create a triangle with these three side lengths.
Step-by-step explanation:
According to the Triangle Inequality Theorem, in order for three given lengths to form a triangle, two of the side lengths must add up to be greater than the length of the largest length. 16+37 makes 53, which is equal to the length of the largest side, not greater.

And can someone give the process of how it's solved? I kind of forgot how to solve it...
Answer:
40 cm
Step-by-step explanation:
Diagonal side: use pythagorean
8^2 + 6^2 = 10^2 => the side is equal to 10
add up w/ 3 others side is 8, 8 and 14
So it is 10 + 8 + 8 + 14 = 40

I don't know if there is supposed to be only one, but both of those do not form right triangles.
Step-by-step explanation:
Evaluate all of them and see if they meet the requirements of the Pythagorean Theorem, a² + b² = c².
1. 38, 80, 89
a² + b² = c²
38² + 80² = 89²
1444 + 6400 = 7921
7844 ≠ 7921.
This is an answer because it doesn't satisfy the Pythagorean Theorem.
2. 16, 63, 65
a² + b² = c²
16² + 63² = 65²
256 + 3969 = 4225
4225 = 4225
This isn't the answer because it satisfies the Pythagorean Theorem.
3. 36, 77, 85
a² + b² = c²
36² + 77² = 85²
1296 + 5929 = 7225
7225 = 7225
This isn't the answer because it satisfies the Pythagorean Theorem.
4. 14, 15, 29
a² + b² = c²
14² + 15² = 29²
196 + 225 = 841
421 ≠ 841
This is an answer because it does not satisfy the Pythagorean Theorem.

Nina made a square picture frame that is 20 cm wide. She wants to wrap a blue ribbon around the outside of the frame two times. How long should the ribbon be?
Answer:
The answer is 160 cm
Step-by-step explanation:
Square is a quadrilateral which has all its sides equal
Perimeter = 2l +2l
=20 times 2 + 20times 2
=40+40
=80
Wrap 2 times= 80 +80
=160cm

What is piecewise function?
A Piecewise Function is a merge of several functions in a single graph. Each function takes a part of the x axis of the graph.
Graph
Domain: The domain of a piecewise-defined function is the union of its subdomains.
Range :The range of a piecewise-defined function is the union of the ranges of each subfunction over its subdomain.
Now,
Straight line graph of x having equation : y = mx + cconstant value of x : x= yexponential curve of x .Thus the domain and range of piecewise function is all real numbers .

A cube has a side length of 8 inches select all the values that represent the cube's inches 8 to the second power 8 to the third power 6x8 to the second power 6x8 8x8x8
Complete Question:
A cube has a side length of 8 inches. Select all values that represent the cubes volume in cubic inches.
Answer:
8³ or 8 * 8 * 8
Step-by-step explanation:
Given the following data;
Length of sides = 8
Mathematically, the volume of a cube is given by the formula;
Volume of a cube = length * length * length ......equation 1.
Or
Volume = length³ ......equation 2.
From equation 1;
Volume of a cube = 8 * 8 * 8
Volume of a cube = 512 cubic inches.
From equation 2;
Volume of a cube = 8³
Volume of a cube = 512 cubic inches.

Answer:
[tex]611\:\text{ft}[/tex]
Step-by-step explanation:
In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. In this angle marked as [tex]42^{\circ}[/tex] is actually the same as the angle with point [tex]P[/tex].
Therefore, we can set up the following equation:
[tex]\tan 42^{\circ}=\frac{550}{x}[/tex], where [tex]x[/tex] is the distance from the coast.
Solving, we get:
[tex]x=\frac{550}{\tan 42^{\circ}},\\x\approx610.84\approx \boxed{611\:\text{ft}}[/tex]

Mario went to a store and bought 3 slices of pizza. The guy at the register said " that would be $3.75". Mario then said "wait, let me add 1 more slice of pizza". How much is his bill now?
Answer:
$5
Step-by-step explanation:
Cost per slice
3.75 / 3 = 1.25
Cost of 4 slices
1.25 * 4 = 5
Answer:
$5
Step-by-step explanation:
First, find how much one slice of pizza costs.
Divide Mario's total by the number of slices he got:
3.75/3
= 1.25
So, one slice of pizza costs $1.25
Add this to his total to find how much his bill will be with one more slice:
3.75 + 1.25
= 5
So, his bill will be $5
What is the perimeter of the triangle?
units
Answer:
Perimeter of triangle= sum of two sides and hypotenuse
Answer:
30 units
Step-by-step explanation:
The perimeter of the triangle is the sum of the two legs, or the shorter sides a and b, and the hypotenuse, the last and longest side, c.
We can already see that side a and b have the lengths of 5 and 12 units.
To find the length of c, use the formula a² + b² = c².
Substitute our a and b values into the formula and solve for c.
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = √c²
13 = c
The third side is 13 units long.
Now we can add our values for a, b, and c together to find the perimeter.
5 + 12 + 13 = P
30 = P
The perimeter is 30 units.
Good luck ^^

Austin is going to invest in an account paying an interest rate of 2.2% compounded daily. How much would Austin need to invest, , for the value of the account to reach $27,000 in 6 years?
Answer:
Principal, P = $23675.90
Step-by-step explanation:
Given the following data;
Interest rate = 2.2 %
Future value = $27000
Time = 6 years
Number of times = 365 days
To find the principal amount, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] 27000 = P*(1 + \frac{0.022}{365})^{365*6}[/tex]
[tex] 27000 = P*(1 + 0.000060)^{2190}[/tex]
[tex] 27000 = P*(1.000060)^{2190}[/tex]
[tex] 27000 = P*(1.1404)[/tex]
[tex] P = \frac {27000}{1.1404} [/tex]
Principal, P = $23675.90
A large home improvement store is considering expanding its selection of moving products, such as cardboard
boxes and packing tape. The store constructs a 90% confidence interval to estimate the proportion of all customers
who have moved houses at least once in the last five years. In the random sample of 620 customers, 201 (32.4%)
replied that they had moved at least once in the last five years. The sample yielded the 90% confidence interval
(0.293, 0.355) for the proportion of all customers who have moved in the past five years. Sheldon, an employee who
wishes to expand the selection of moving products, claims that more than 1 in 4 customers have moved in the past
five years. Zachary, another employee, urges Sheldon to be bolder in his claim and say that more than 1 in 3
customers have moved in the past five years. Based on the confidence interval, which employee's claim is
plausible?
Answer:
Based on the confidence interval, Sheldon's claim is plausible
Step-by-step explanation:
The number of customers in the sample, n = 620 customers
The number of customers that replied that they had moved at least once in the last five years = 201 (32.4%)
The 90% confidence interval for the sample = (0.293, 0.355)
Let 'p' represent the proportion of all customers who have moved in the past five years
The proportion of customers Sheldon claimed have moved in the past five years, p > 1 in 4 (0.25)
The proportion Zachary urges Sheldon to claim is, p > 1 in 3 (0.[tex]\overline 3[/tex])
Given that the lower estimate of the confidence interval is 0.293 (>0.25) and upper bound of the confidence interval is 0.355 (> 0.[tex]\overline 3[/tex]), and that 0.26 in also more than 1 in 4 but less than 0.293, but however that 0.293 which is within the 90% confidence interval is less than 0.[tex]\overline 3[/tex] or 1 in 3, as opposed to what Zachary urges Sheldon to claim, Sheldon's claim is more plausible.
