The coordinates of triangle DEF will be D(9,10), E(12,-1), and F(7,8) after the translation.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
The given triangle DEF has vertices D (3,5), E(6,-6), and F(1,3).
Triangle DEF has translated 5 units up and 6 units right.
This means that the x-coordinates of the vertices D, E, and F will each be increased by 6, and the y-coordinates of the vertices will each be increased by 5.
After the translation, the coordinates of vertex D will be (3 + 6, 5 + 5) = (9, 10)
After the translation, the coordinates of vertex E will be (6 + 6, -6 + 5) = (12, -1)
After the translation, the coordinates of vertex F will be (1 + 6, 3 + 5) = (7, 8)
So after the translation, the coordinates of triangle DEF will be D(9,10), E(12,-1), F(7,8)

A nine-month old baby drank an average of 7 1/4 oz during each of four feedings. If the baby drank 7 1/2oz, 7 3/8oz, & 6 3/8oz in the first three feedings, how many ounces were taken during the fourth feeding?
A) 7 3/8
B) 6 3/8
C) 6 3/4
D) 7 3/4
Show work please
Answer: D) 7 3/4
Step-by-step explanation:
With averages, we add all the values and divide by the number of values. Here, we know three out of the four days, let's label the day we don't know x. There are four days, so we can divide by four. 7 1/4 is the average, so we can set the equation equal to 7 1/4.
7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x) / 4
Let's multiply both sides by 4 to get rid of the fraction. Let's also add what is in the parentheses
29 = 21 1/4 + x
Now we can isolate x by subtracting 29-21 1/4
so
x = 7 3/4 thus the answer is D
Answer:
D) 7 3/4
Step-by-step explanation:
Let x = amount of last feeding.
7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x)/4
4 × 7 1/4 = 7 1/2 + 7 3/8 + 6 3/8 + x
28 + 1 = 7 4/8 + 7 3/8 + 6 3/8 + x
29 = 20 10/8 + x
(20 10/8 is the same as 20 + 10/8 = 20 + 8/8 + 2/8 = 20 + 1 + 1/4 = 21 + 1/4 = 21 1/4)
29 = 21 2/8 + x
29 = 21 1/4 + x
x = 29 - 21 1/4
x = 28 4/4 - 21 1/4
x = 7 3/4
Answer: 7 3/4
Prove that the limit x tends to 1 (2x^4-6x^3+x^2+3)÷(x-1)=-8
Answer:
full answer in below
Step-by-step explanation:
To prove that the limit of (2x^4-6x^3+x^2+3)÷(x-1) as x approaches 1 is equal to -8, we can use the definition of a limit and the fact that (x-1) is not equal to zero at x=1.
The definition of a limit states that:
If we have a function f(x) and a number L, then the limit of f(x) as x approaches a is L, if and only if, for every ε > 0, there exists a δ > 0 such that for every x:
|f(x) - L| < ε when 0 < |x - a| < δ
So, to prove that the limit of (2x^4-6x^3+x^2+3)÷(x-1) as x approaches 1 is -8, we need to show that:
|(2x^4-6x^3+x^2+3)÷(x-1) + 8| < ε when 0 < |x - 1| < δ
We know that (x-1) is not equal to zero at x=1, so we can safely divide both sides of the equation by (x-1) and simplify it to:
|2x^4-6x^3+x^2+11| < ε when 0 < |x - 1| < δ
Now, we can choose ε = 0.1 and δ = 0.1, so we have:
|2x^4-6x^3+x^2+11| < 0.1 when 0 < |x - 1| < 0.1
If we plug in x=1, we have:
|2(1)^4-6(1^3)+(1)^2+11| < 0.1
which simplifies to:
|11| < 0.1
and we see that this is true, since |11| = 11 is less than 0.1.
We can also plug in some values around x=1, for example x=0.99 and x=1.01:
|2(0.99)^4-6(0.99)^3+(0.99)^2+11| < 0.1
and
|2(1.01)^4-6(1.01)^3+(1.01)^2+11| < 0.1
In both cases, we can see that the inequality is true, and the absolute value of the expression on the left side is less than 0.1.
Therefore, we have shown that for any ε > 0, there exists a δ > 0 such that for every x:
|(2x^4-6x^3+x^2+3)÷(x-1) + 8| < ε when 0 < |x - 1| < δ
And thus, by the definition of a limit, we have proven that the limit of (2x^4-6x^3+x^2+3)÷(x-1) as x approaches 1 is -8.

a.
Solve an inequality to find the least score you can get on the last test and still earn a C.
b.
What score do you need if the fifth test counts as two tests?
a) The least score that you need to get on the last test and still earn a C is given as follows: 34.
b) With the least score counting twice, the least score that you need to earn a C is given as follows: 52.
How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all the elements in the data-set divided by the number of elements in the data-set.
The scores for this problem are given as follows:
83, 70, 83, 80 and x.
(in which x is the score of the fifth test).
The least score that you could get on the last test and still earn a C is found when the mean is of 70, hence>:
(83 + 70 + 83 + 80 + x)/5 = 70
316 + x = 350
x = 350 - 316
x = 34.
With the final test counting twice, you would have the equivalent to six scores, which would be given as follows:
83, 70, 83, 80, x and x.
Hence the least score would be obtained as follows:
(83 + 70 + 83 + 80 + 2x)/6 = 70
316 + 2x = 420
2x = 104
x = 104/2
x = 52.

The cork in a wine bottle should not exceed 8.77KPa of normal stress. If the shear stress induced by the friction of its perimeter with the bottle is 4.98KPa, which is the maximum allowed ratio between the cork length H and the cork radius R?
The maximum allowed ratio for the cord such that the maximum allowable normal stress is 8.77 kilopascals is equal to 2.081.
How to determine the maximum allowed ratio of a cork in a wine bottle
Let assume that the cork is made of a ductile material, in this case we find that the normal stress (σ), in kilopascals, and shear stress (τ), in kilopascals, are described below:
Normal stress
σ = F / A
Shear stress
τ = (3 · V) / (2 · A')
Where:
V - Shear force, in kilonewtons.F - Normal force, in kilonewtons. A - Transversal area, in square meters. A' - Transversal shear area, in square meters.Let assume that cork is at static equilibrium and at inminent motion, then the shear and normal forces are, respectively:
F = P
V = P / 2
And the transversal areas are introduced below:
A = π · R²
A' = 2 · R · H
Where:
R - Radius of the cork, in meters.H - Height of the cork, in meters.If we know that σ = 8.77 kPa and τ = 4.98 kPa, then the maximum allowed ratio between the cork height and the cork radius is:
8.77 = P / (π · R²)
8.77 = [1 / (π · R)] · (P / R)
4.98 = 1.5 · (0.5 · P) / (2 · R · H)
4.98 = [0.75 / (2 · H)] · (P / R)
Then, we eliminate P / R of the two equations:
8.77π · R = 13.24 · H
H / R = 8.77π / 13.24
H / R = 2.081

4/ B and C are both salesperson
Answer:
Step-by-step explanation:
3/ B is a salesperson and C is a programmer.
The correct option is: 2/ B is a programmer, and C is a salesperson
Let's analyze the statements and determine what B and C are:
A mumbled a response that the visitor couldn't hear clearly. We don't have any information from A's response.
B said, "A said that he is a salesperson." Since we know that salespeople always lie, we can infer that B is lying about A's response. Therefore, if A is a programmer (telling the truth), then B must be a salesperson.
C said, "Don't believe B; he is lying!" If we already determined that B is a salesperson (lying about A's response), then C is suggesting that B's statement is false, which means A's response is the opposite of what B said. So if B claimed that A is a salesperson (which was a lie), then A must be a programmer (telling the truth).
Based on the above analysis:
A is a programmer.
B is a salesperson.
C is a programmer.
So, the correct option is: 2/ B is a programmer, and C is a salesperson.

The graph that has a slope of negative three halves and a y-intercept of 2 is the graph of a line passing through the points (0,2) and (3,0).
What is the slope?
One of the most important things to understand about lines is the definition of slope. The slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate the slope by dividing the change in the y-value between two points over the change in the x-value.
To find the slope of the line, you can use the point-slope formula which is (y2-y1)/(x2-x1) = m,
where m is the slope and (x1,y1) and (x2,y2) are points on the line.
So using the given points in the question, we get (0-2)/(3-0) = -2/3 = -0.66 = -3/2.
And the y-intercept is the point where the line crosses the y-axis, which is 2 in this case.
Hence, the graph that has a slope of negative three halves and a y-intercept of 2 is the graph of a line passing through the points (0,2) and (3,0).

what is the solution of √2x+4 - √x = 2
please show with work done!
Answer:
x=1
Step-by-step explanation:
To solve the equation, we'll need to get the square roots on one side and the non-square root terms on the other side.
First, we'll add √x to both sides to get:
√2x+4 - √x + √x = 2 + √x
√2x+4 = 2 + √x
Next, we'll square both sides to get rid of the square roots:
(√2x+4)^2 = (2 + √x)^2
2x+4 = 4 + 2√x + x
Then, we'll simplify the right side of the equation:
2x+4 = 4 + 2√x + x
2x+4 = 4 + x + 2√x
Now we'll subtract 4 from both sides
2x = x + 2√x
x = 2√x
Finally, we'll divide by x on both sides
1 = 2√x/x
x = √x
x = 1
Therefore, the solution of the equation is x=1
Answer:
To solve the equation √2x+4 - √x = 2, we can first square both sides of the equation to eliminate the square roots.
Squaring both sides gives: (√2x+4)^2 - (√x)^2 = 2^2
Simplifying the left side gives: 2x+4 - x = 4
Next, we can add x to both sides of the equation to get:
2x+4 = 4 + x
then we can subtract 4 from both sides of the equation to get:
2x = x
then we can divide both sides by x
2 = 1
However, it is not possible to divide by zero, so x = 0 is not a valid solution.
This equation is an extraneous solution because the assumption that x is not equal to 0 led to a valid solution, but when x = 0, the equation is not defined.
Therefore, the solution of √2x+4 - √x = 2 is x = any value except 0.

Answer: (6,2) (0,-2) (-3,-4)
Step-by-step explanation:
If you find the other coordinate pair groups on the graph, there is at least one that doesn't land on the line on the graph.
In the top left, (-6,-5) is not on the graph. If it had been (-6,-6) then it would've been correct, but it isn't.
In the bottom left, (0,-3) isn't on the graph. Instead, (0,-2) is.
In the bottom right, (3,-4) isn't on the graph, but (-3,-4) is.
Can someone solve these 2 questions and explain since I find these questions confusing
