Answer:
x = 1
y = 9
Step-by-step explanation:
The diagonals of the parallelogram bisect each other. Therefore:
✔️2x + 13 = 15
2x + 13 - 13 = 15 - 13
2x = 2
2x/2 = 2/2
x = 1
✔️5y - 36 = y
5y - 36 - 5y = y - 5y
-36 = -4y
-36/-4 = -4y/-4
9 = y
y = 9
Let O be a quadrant I angle with cos(0) ✓11/7 Find sin(20).
Answer:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \cos(\theta)=\frac{\sqrt{11}}{7}[/tex]
Where θ is in QI.
And we want to determine sin(2θ).
First, note that since θ is in QI, all trig ratios will be positive.
Next, recall that cosine is the ratio of the adjacent side to the hypotenuse. Therefore, the adjacent side a = √(11) and the hypotenuse c = 7.
Then by the Pythagorean Theorem, the opposite side to θ is:
[tex]b=\sqrt{(7)^2-(\sqrt{11})^2}=\sqrt{49-11}=\sqrt{38}[/tex]
So, with respect to θ, the adjacent side is √(11), the opposite side is √(38), and the hypotenuse is 7.
We can rewrite as expression as:
[tex]\sin(2\theta)=2\sin(\theta)\cos(\theta)[/tex]
Using the above information, substitute. Remember that all ratios will be positive:
[tex]\displaystyle =2\Big(\frac{\sqrt{38}}{7}\Big)\Big(\frac{\sqrt{11}}{7}\Big)[/tex]
Simplify. Therefore:
[tex]\displaystyle \sin(2\theta)=\frac{2\sqrt{418}}{49}\approx0.8345[/tex]
Given y = alog(x + c) + d. What would happen to the graph if you changed the value of d? Describe both positive and negative
values.
A)
B)
Changing the value of d would cause a vertical stretch or shrink. A negative
value would also cause a reflection over the x-axis.
Changing the value of d would cause a horizontal stretch or shrink. A
negative value would also cause a reflection over the y-axis.
Changing the value of d would move the graph up and down (vertically). A
positive d value would move the graph up and a negative d value would
move the graph down.
Changing the value of d would move the graph left and right (horizontally).
A positive d value would move the graph right, and a negative d value
would move the graph left.
C)
D)
Answer: A
Step-by-step explanation:
I just took the USATESTPREP quiz and that is the answer.
Option (C) will define the changes in the graph of the function with the values of 'd'.
Given function in the question → y = alog(x + c) + d
Rules for the translation of a function,
If a function y = f(x) is shifted 'h' units upwards on y-axis, rule for the translation will be → y = f(x) + hIf the function y = f(x) is shifted 'h' units downwards, rule for the translation → y = f(x) - hHence, in the given function y = alog(x + c) + d, positive value of 'd' will define the shifting of the parent function upwards.
And for the negative value of 'd' will define the shift of the function downwards.
Option (C) will be the correct option.

One can use the angle bisector theorem to solve this problem. The angle bisector theorem states:
[tex]\frac{a_1}{b}=\frac{a_2}{c}[/tex]
Where ([tex]a_1[/tex]) and ([tex]a_2[/tex]) are a part of the side that is intersected by the angle bisector and ([tex]b[/tex]) and ([tex]c[/tex]) are the other two sides in the triangle. Substitute in the given values and solve for the unknown.
[tex]\frac{4}{8}=\frac{6}{y}[/tex]
Simplify,
[tex]\frac{1}{2}=\frac{6}{y}[/tex]

Suppose that P dollars in principal is invested in an account earning 2.1% interest compounded continuously. At the end of 2 yr, the amount in the account has earned $193.03 in interest.
A) Find the original principal.
B) Using the the original principal from part (a) and the model A = Pe", determine the time required for the investment to reach $6000.
Answer:
See explanation
Step-by-step explanation:
Recall that
Amount = Principal + Interest
The formula is;
A = P(1 + r)^n
Where;
P= principal, n = time and r = rate
Hence;
P + I = P(1 + r)^n
P + 193.03 = P(1.021)^2
P + 193.03 = 1.04P
P - 1.04P = - 193.03
-0.04 P = - 193.03
P = 193.03/0.04
P = $ 4825.75
B) When A = $6000, n=?
From;
A= P(1 + r)^n
6000 = 4825.75 (1.021)^n
6000/4825.75 = (1.021)^n
1.24 = (1.021)^n
Taking logarithm of both sides;
log 1.24 = n log 1.021
n = log 1.24/log 1.021
n = 0.0934/0.009
n = 10 years
how did you determine ray
Answer:
In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.
Answer:
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).

Answer:
this is 4(2x−3)=4(2x)−4(3)distributive property
Answer:
The Distributive Property
Step-by-step explanation:
The distributive property states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum. For example, a(b + c) = ab + ac. The division property of inequality states that two unequal values divided by a positive number retain the same relationship.

The measure of angle A is 86.
What is a kite?A kite is a flying object that is tethered to the ground by a string or a cord. It typically has a light framework of bamboo, plastic, or other materials, covered with paper or fabric, and often in the shape of a diamond or triangle.
We have,
From the figure,
We see that,
6x + 4 + ∠A = 180
Now,
∠A = 4x + 26
So,
6x + 4 + 4x + 26 = 180
10x + 30 = 180
10x = 180 - 30
10x = 150
x = 15
Now,
∠A = 4x + 26 = 4 x 15 + 26 = 60 + 26 = 86
Thus,
The measure of angle A is 86.
