Explanation:

15. x = 148°, z = 32°

In a parallelogram, adjacent angles are supplementary, so must add to 180°. That also means opposite angles are congruent.

___

17. x = 8, y = -3

The diagonals bisect each other, so ...

2x -4 = 12

x = (12 +4)/2 = 8

and ...

y +10 = 7

y = 7 -10 = -3

__

21. The diagonals of a parallelogram bisect each other, so their point of intersection is their midpoint. The midpoint of WY can be computed as ...

P = (W+Y)/2 = ((-3, 5) +(3, 1))/2 = (0, 6)/2 = (0, 3)

The diagonals intersect at (0, 3).

Step-by-step explanation:

Landry is opening two savings accounts. He is opening the first account with an initial deposit of $500. The account will compound continuously each year at a rate of 3%.

He is opening the second account with an initial deposit of $300. The account will compound continuously each year at a rate of 5%.

Landry would like to know how long it will take for the balance of the two accounts to be equal.

Create a system of equations to model the situation above, and use it to determine if there are any solutions. If there are any solutions, determine if they are viable or not.

Answers

Answer:

Never. (Not viable)

Step-by-step explanation:

3% of 500=15

5% of 300=15

Since both of them would get $15 a year, then they would stay the same amount apart. For example, when the first account reached 515 dollars, the second one would be at 315 dollars. Thus, they'd always be 200 dollars apart.

However!

Since it is a compound interest, and if there is the original 7% a year, the formula we'll use for this is the simple interest formula, or:  

I=Pxrxt

Where:

P is the principal amount, $500.00.

r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 500 × 0.03 × 5 to get that:  

The interest is: $75.00

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),  

or 500.00 + 75.00 = 575.00. For example:

If you borrowed the $500.00, you would now owe $575.00

If you loaned someone $500.00, you would now be due $575.00

If owned something, like a $500.00 bond, it would be worth $575.00 now.

You want to calculate the interest on $300 at 5% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:  

I=Pxrxt

Where:

P is the principal amount, $300.00.

r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 300 × 0.05 × 5 to get that:  

The interest is: $75.00

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),  

or 300.00 + 75.00 = 375.00. For example:

If you borrowed the $300.00, you would now owe $375.00

If you loaned someone $300.00, you would now be due $375.00

If owned something, like a $300.00 bond, it would be worth $375.00 now.

what relationship has a zero slope

Answers

Answer:

the far left table

Final answer:

In Mathematics, a zero slope represents a horizontal line that can be defined by the equation y = C, where C is a constant, showing no relationship between changes in x and y.

Explanation:

In Mathematics, when discussing about slopes, a zero slope signifies that there is no change in y for any change in x. This results in a straight horizontal line when graphed. A real-life example might be that if you were walking on a flat road, the slope of that road is zero because your altitude isn't changing no matter how far you walk horizontally.

The relationship involved in a zero slope scenario can be defined by the equation y = C, where C is a constant. This means that y will remain constant despite any changes in x.

The equation of a line with zero slope can be declared as y = b, where b is the y-intercept. This shows no correlation between x and y as x varies but y remains constant.

Answer: Option B

[tex]y = 0.75cos(2\phi)[/tex]

Step-by-step explanation:

The general cosine function has the following form  

[tex]y = Acos(b\phi) + k[/tex]

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

[tex]\frac{2\pi}{b}[/tex] is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

The maximum value of y is is 0.75 and the minimum is -0.75. Then the amplitude A is:  

[tex]A =\frac{0.75-(-0.75)}{2}\\\\A= 0.75[/tex]

Then [tex]k=0[/tex]

The cycle is repeated every [tex]\pi[/tex] units  

So the period is [tex]\pi[/tex]

Thus:

[tex]\frac{2\pi}{b}=\pi\\\\ b=\frac{2\pi}{\pi}\\\\ b=2[/tex]

The function is:

[tex]y = 0.75cos(2\phi)[/tex]

when [tex]\phi=0[/tex] y is maximum therefore [tex]y=0.75[/tex] As shown in the graph

So, option A is correct.

Final answer:

To draw the angle -3pi/4 in standard position, we measure 135 degrees clockwise from the positive x-axis.

Explanation:

To draw the angle below in standard position, -3pi/4, you begin from the positive x-axis (which is usually referred rightward).

In standard position, positive angles are measured counterclockwise and negative angles are measured clockwise. Since we're dealing with a negative angle of -3pi/4, we will measure this clockwise.

The angle -3pi/4 corresponds to 135 degrees (because -3pi/4 is -3 * 180 degrees/2 = -135 degrees). You would measure 135 degrees clockwise from the positive x-axis to draw this angle in standard position.

Can somebody teach me inscribed angles! My 40 question summarize on circles in geometry is today and I need help on everything! ​

Answers

Inscribed angles are pretty easy, they're always half the corresponding central angle.  The arc measure are always of central angles.

1. We're told to arc is 62 degrees so the inscribed angle is half,

WXY = 31 degrees.

2. Here we're told the inscribed angle is 113 degrees so the arc is double,

DGF=226 degrees

3. Angles which subtend a diameter are always right angles.

PQR = 90 degrees

4. If we draw DC we see it's a radius too, so DC=DB and we have an isosceles triangle so DCB=47 degrees so BDC=180-47-47=86.  The central angle is the arc measure so

BC=86 degrees

5. Angle JNK=53 degrees and angles NJK=NKJ because we have an isosceles triangle, two sides radii.  So NKJ=(180-53)/2.

Similarly NKL=(180-65)/2

So angle JKL=NKJ+NKL=180 - (65+53)/2 = 180 - 118/2 = 121 degrees

I better leave the rest for you.

Final answer:

An inscribed angle is formed by two secant lines intersecting on a circle's circumference and is half the measure of the central angle intercepting the same arc. Fundamental theorems like the Pythagorean theorem and mnemonic SOHCAHTOA are important in geometry, especially when dealing with circles and triangles.

Explanation:

An inscribed angle is formed when two secant lines of a circle intersect on the circle's circumference. The value of an inscribed angle is always half the measure of the central angle that intercepts the same arc.

This is a foundational concept in geometry that is often linked to other geometric properties and theorems, such as the relationship between angles and arcs, and the behavior of angles within and outside of circles.

Knowing how to work with inscribed angles is crucial, particularly when dealing with problems involving circles.

For example, if you know the measure of the central angle, you can easily find the inscribed angle by dividing the central angle by 2. Recall other basic geometrical facts, such as the Pythagorean theorem, which states that in a right triangle, a² + b² = c² (where c is the hypotenuse), and the mnemonic SOHCAHTOA which helps remember the relationships of sides and angles in right triangles.

To help visualize these concepts, sketching triangles and remembering that the angles of a triangle sum up to 180 degrees can be helpful. Plane geometry forms the basis for understanding these principles, which is essential in tackling more advanced problems in circles and other geometric figures.

The area of a rectangle is (x4 + 4x3 + 3x2 – 4x – 4), and the length of the rectangle is (x3 + 5x2 + 8x + 4). If area = length × width, what is the width of the rectangle?

Answers

Answer:

Width = x-1

Step-by-step explanation:

Given

Area of rectangle=A= x^4+4x^3+3x^2-4x-4

Length of Rectangle=L= x^3+5x^2+8x+4

We have to find width

Width of rectangle=W= ?

We know that the formula for the area of triangle is:

Area of Rectangle=Length*Width

A=L*W

Since we need the value of width, length will be moved to the left of equals to.

A/L=W

W= (x^4+4x^3+3x^2-4x-4)/(x^3+5x^2+8x+4)

After long division, we will get

Width=W=x-1

If jay Berry put the $100.00 in a savings account that earned 12% interest every month. How much would he have in one year? 10 pts

How much would he have in five years?

Answers

Answer: Alright get ready for a long explanation

he would have 820.00$ in his savings account after the 5 years

Step-by-step explanation:

if he earns 12% interest then you would have to multiply 100 by the 12/100 which is .12 in decimal form.

100 TIMES .12 = $12.00

because we are doing this in months you need to multiply the amount he makes per month by the amount of months that the 100 dollars is in the bank account.

Alright so now that thats over, he makes 12 dollars every month

thers 12 months in a year, so you would have to do 12 (the number of moths) times 5 (the amount of years) that equals 60.  

60 TIMES the amount he makes per month ($12) equals $720.00

LASTLY! add the amount he made to the original amount and you get the answer of $820.00

Answer:

x = 3 is a true solution.

The zeros of 0 = x2 – 5x + 6 are possible solutions to the radical equation.

Step-by-step explanation:

Given in the question an equation,

√(x-2) - 4 = x - 6

√(x-2) = x - 6 + 4

√(x-2) = x -2

Take square on both sides of the equation

√(x-2)² = (x -2)²

x - 2 = x² - 4x + 4

0 = x² - 4x - x + 4 + 2

0  = x² - 5x + 6

a = 1

b = -5

c = 6

x = -b±√(b²-4ac) / 2a

x = -(-5)±√(5²-4(1)(6)) / 2(1)

x = 5 ± √1 / 2

x = 5 + 1 / 2 or  5 - 1 /2

x = 3 or x = 2

x=3

√(3-2)-4=3-6

√1 -4 = -3

 1 - 4 = -3

    -3 = -3

x=2

Answers

Answer:

Each team recieved $312

Step-by-step explanation:

You will take $5145 - 777 = 4368 which is the balance

4368 of the balance  ÷ 14 teams =312

each team received  $312

Final answer:

After paying the expenses of $777 from the fund-raising total of $5145, $4368 was left. When this amount was divided evenly amongst 14 soccer teams, each team received $312.

Explanation:

To solve the problem, we first need to subtract the expenses from the total fund-raising amount. This gives us $5145 - $777 = $4368.

After the expenses are taken into consideration, the remaining money is divided evenly among the 14 soccer teams. This is calculated by taking the remaining money and dividing it by the number of teams, $4368 ÷ 14 = $312.

So, each team will receive $312 after all the expenses are paid.
