We want to know the image point after a translation.
A translation is basically a shift in the position of the object.
The object point is (5, -5) and it translates 2 units right and 3 units up.
That means there is a shift +2 units on the x axis and +3 units on the y axis.
Therefore, the image point is:
(5 + 2, -5 + 3)
= (7, -2)
That is the image point.
how much must be deposited at the beginning of every six months in an account that pays 6% compounded semi-annually so that the account will contain 35,000 at the end of five years the semi-annual payments are___?round to 2 decimal places
In order to determine the initial investment, use the following formula for the composed interest:
[tex]I=P(1+\frac{r}{n})^{nt}[/tex]where:
P: initial investment = ?
r: interest rate = 6% = 0.06
n: number of times per time period = 6
t: time period = 5 x 2 = 10
I: final account = 35,000
replace the previous values of the parameters and solve for P, as follow:
[tex]\begin{gathered} 35000=P(1+0.06/6)^{6\cdot10}=P\cdot1.816 \\ P=35000/1.816 \\ P=19273.13 \end{gathered}[/tex]Hence, the initial investment was 19,273.13
in an art room there are three easels for every five children if there are 25 children how many easels are there
Given 3 easels for every 5 children
So, there are x easels for 25 children
Using the ratio and the proportional
3 : 5 = x : 25
[tex]\frac{3}{5}=\frac{x}{25}[/tex]so, solve for x
[tex]x=\frac{3\cdot25}{5}=\frac{75}{5}=15[/tex]So, the number of easels for 25 children = 15 easels

what line is perpendicular to the line y=2x+4 ? what line is parallel to line y + 2x+4 ? *options are for both answers*
Given the line : y = 2x + 4
the general equation of the line is y = mx + b
where m is the slope , b is the y intercept
By comparing the given line with the general form
so, the slope of the given line is :
m = 2
the slope of the perpendicular line will be = -1/m
so, the slope of the perpendicular line = -1/2
The slope of the parallel line = the slope of the given line
So, the slope of the parallel line = 2
so, the answer is:
the perpendicular line is : y = (-1/2) x + 10
The parallel line is : y = 2x + 1
based on this relationship which could be the correlation coefficient?
Based on the relationship in the given table the correlation coefficient is -0.9985 .
Let us define a few variables first.
X: X Values
Y: Y Values
Mx: Mean of X Values
My: Mean of Y Values
Deviation scores = X - Mx , Y - My
Deviation Squared = variance = (X - Mx)² , (Y - My)²
Product of Deviation Scores = (X - Mx)(Y - My):
Now we will use the defined variables to calculate the correlation coefficient
X Values
∑ = 118.5
Mean = 11.85
∑(X - Mx)² = Sx = 1283.705
Y Values
∑ = 206
Mean = 20.6
∑(Y - My)² = Sy = 16804.4
X and Y Combined
N = 10
∑(X - Mx)(Y - My) = -4637.7
R Calculation
r = ∑((X - My)(Y - Mx)) / √((Sx)(Sy))
r = -4637.7 / √((1283.705)(16804.4)) = -0.9985
The correlation coefficient is the only statistical measure of the given strength of a linear relationship that is amongst the two variables. Its values normally range from -1 to 1.
Based on a correlation coefficient of 1, which indicates a completely negative or inverse relationship, values in one series increase as those in the other decline, and vice versa.
Hence the correlation coefficient is -0.9985

An electrician leans an extension ladder against the outside wall of a house so that it
reaches an electric box 27 feet up. The ladder makes an angle of 62° with the ground.
Find the length of the ladder. Round your answer to the nearest tenth of a foot if
necessary?
Answer: 59.5 ft
Step-by-step explanation:
When the ladder lay on the wall it makes a triangle. And for this equation, we have to use the sin to find the length.
Sin = opposite / hypotenuse
Sin 62 = 27 / h

We want to order the functions from widest to narrowest:
[tex]\begin{gathered} y=3x^2 \\ y=2x^2 \\ y=4x^2 \end{gathered}[/tex]To do this, we have to plot the graphs of the functions by using a table of values.
Let us find the values of the functions for values of x = -2, 0, 2
For the first function:
[tex]\begin{gathered} y=3x^2 \\ \Rightarrow x=-2: \\ y=3(-2)^2=3*4 \\ y=12 \\ \Rightarrow x=0: \\ y=3(0)^2=3*0 \\ y=0 \\ \Rightarrow x=2: \\ y=3(2)^2=3*4 \\ y=12 \end{gathered}[/tex]Hence, its table is:
For the second function:
[tex]\begin{gathered} y=2x^2 \\ \Rightarrow x=-2: \\ y=2(-2)^2=2*4 \\ y=8 \\ \Rightarrow x=0: \\ y=2(0)^2=2*0 \\ y=0 \\ \Rightarrow x=2: \\ y=2(2)^2=2*4 \\ y=8 \end{gathered}[/tex]Hence, its table is:
For the third function:
[tex]\begin{gathered} y=4x^2 \\ \Rightarrow x=-2: \\ y=4\left(-2\right)^2=4*4 \\ y=16 \\ \Rightarrow x=0: \\ y=4(0)^2=4*0 \\ y=0 \\ \Rightarrow x=2: \\ y=4(2)^2=4*4 \\ y=16 \end{gathered}[/tex]Hence, its table is:
Now, let us plot the graphs of the functions:
Therefore, from the graph, we see that the order of the functions from widest to narrowest is:

Associative Property
Commutative Property
Distributive Property
Identity Property.
This is the Commutative Property. It states that when addition takes place, the addends may switch positions with another addend.
The given expression −3+ 5 = 5 + (−3) is showing the commutative Property. The correct option is B.
The cumulative property states that if the position of the numbers when they are in addition is changed then it will not affect the final result of the addition. If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics.
The given expression is −3+ 5 = 5 + (−3).
From the cumulative property, the expression can be solved. The two expressions will have the same value but the frame of writing the expression is different.

3. In the figure below, XU is the midsegment of TVW and is parallel to VW, determine the length of XU. (3 points) 11x + 2 U 10x + 16
If XU is the midsegment of TVW, then, it is necessary that:
(11x + 2)/(10x + 16) = 1/2
multiply the previous equation by 10x + 16:
11x + 2 = 1/2(10x + 16)
11x + 2 = 5x + 8 subtract 5x and 2 both sides
11x - 5x = 8 - 2
6x = 6
x = 6/6
x = 1
THe length of XU is:
XU = 11x + 2 = 11(1) + 2
XU = 13
The product of the ages (in days) of two newborn babies Simran and Jessie in two dayswill be 48 more than the product of their ages today. How old are the babies if Jessie is 2days older than Simran?
Given that:
- The product of the ages (in days) of babies Simran and Jessie in two days
will be 48 more than the product of their ages today.
- Jessie is 2 days older than Simran.
Let be "j" Jessie's age (in days) and "s" Simran's age (in days).
You can set up the following System of Equations using the data given in the exercise:
[tex]\begin{cases}(j+2)(s+2)=js+{48} \\ j={s+2}\end{cases}[/tex]You can use the Substitution Method to solve the system:
1. Substitute the second equation into the first one:

[tex](s+4)(s+2)=s^2+2s+48[/tex][tex](s)(s)+(s)(2)+(4)(s)+(4)(2)=s^2+2s+48[/tex][tex]s^2+2s+4s+8=s^2+2s+48[/tex][tex]\begin{gathered} 4s=48-8 \\ \\ s=\frac{40}{4} \\ \\ s=10 \end{gathered}[/tex]3. Substitute "s" into the second original equation and evaluate:

What do we mean by the congruency of triangles?Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.
You can move, flip, twist, and turn these triangles to produce the same effect.
So, first label the two triangles as △ABC and △ADE.
Now, to prove that △ABC ≅ △ADE:
BA = DA (Given)
