Answer:
The image point of (-7, 1) after reflection across the y-axis is:
(7, 1)Step-by-step explanation:
When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.
Thus,
The rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
In our case, we are given the point (-7, 1)
Let say the point is A(-7, 1).
Thus, using the rule to reflect a point across the y-axis is:
P(x, y) → P'(-x, y)
A(-7, 1) → A'(-(-7), 1) → A'(7, 1)
Therefore, the image point of (-7, 1) after reflection across the y-axis is:

A farmer wants to fence a piece of his land. Two sides of the triangular field have lengths of 120 feet and 325 feet. The measure of the angle between those sides is 70 degrees. How much fencing will a farmer need?
Farmer need 750.5 feet fencing for his triangular field.
What is triangle?"Triangle is two dimensional geometrical shape with three sides and three vertices. Sum of all the angles of a triangle is equals to 180°.
Formula used
Cosine rule
As per the diagram,
cosθ = (b² +c² -a²) / 2bc
cos 70° = 0.3420
According to the question,
Let AB = c , AC = b are given sides of measure 120 feet and 325 feet respectively.
and BC = a
Angle between given sides be θ = 70°
Substitute the value in the formula we get,
cos70° = [ (325)² +(120)² - a²] / 2(120)(325)
⇒ 0.3420 = [ 120025 - a²] / 78000
⇒ 120025 -a² = 26676
⇒ a² = 93349
⇒ a = 305.5
Total fencing required for triangular field = AB + BC +CA
= 120 + 325 + 305.5
= 750.5 feet
Hence, farmer need 750.5 feet fencing for his triangular field.

Answer:
[tex]y = 7x [/tex]
Step-by-step explanation:
To find the slope, which is
[tex] \frac{rise}{run} [/tex]
find how high up the y value goes before it intersects the x line at a specific point. It seems that they intersect at (70,10) which would be 70/10 or 7/1. 7/1 is just 7 so the slope of it is just that, 7. As for finding B, look at where the line starts, of it's above or below 0, then you would add or subtract whatever number it starts at (subtract for negative, add for positive). In this case it seems that the intercept is right at 0 so you would neither add or subtract anything. :)

Find the coordinate point for D that would make ABDC a rhombus.
Point A (2,2)
Point B (3,4)
Point C (4,1)
Point D (?)
A. (5,4)
B. (5,2)
C. (5,3)
D. (3,0)
Answer:
(5,3)
Step-by-step explanation:
I took the test and go it right!
The coordinate point for D is (5, 3). Therefore, option C is the correct answer.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.
Given that, Point A (2,2), Point B (3,4) and Point C (4,1)
The coordinate point for D that would make ABDC a rhombus.
So, the coordinate point for D is (5, 3).
Therefore, option C is the correct answer.

You invest $125,000 in an account that earns 4.75% annual
interest, compounded continuously.
a. What is the value of the account after 15 years?
Step-by-step explanation:
step 1. let's call the amount of money A, the initial amount A¡, the rate r, and the time t.
step 2. A = A¡e^(rt) (continuously compounding equation)
step 3. A = 125000e^((.0475)(15))
step 4. A = $254,885.32
The value of the account after 15 years will be $254885.
In theory, continuously compounded interest means that an account balance is constantly earning interest and reinvesting that interest so that it, too, earns interest.p explanation.
In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor.
Given that you invest $125,000 in an account that earns 4.75% annually for 15 years of the time.
The compound interest will be calculated as:-
[tex]P(t) = P_o\times e^{rt}\\P(t) = 1250000\times e^{0.0475\times 15}[/tex]
P(t) = $254885
Hence, the value of the account after 15 years will be $254885.
