Answer:

VXY = 38 degrees

YXW = 19 degrees

Step-by-step explanation:

The line XY is a angle bisector, meaning it divides the angle in half. YXW is the angle between the XY and XW lines. Which we know is 19 degrees.

Since we know the XY line divides the angle in half, we know VXW is also 19 degrees.

Therefore, VXW would be the sum of VXY and YXW: 19 + 19 = 38.

Greta is opening a savings account. She starts with $100 and plans to add $50 each week. What is the unit rate of change for thi

Semmy [17]

Greta starts with $100 in her savings account

She adds $50 each week

Balance after week 1 = 100 + 50 = 150

Part A

Unit rate of change here is = $\frac{\text{Balance after week 1 - Initial balance}}{\text{Initial balance}} * 100$

⇒ Unit rate of change here is = $\frac{\text{150 - 100}}{\text{100}} * 100$

⇒ Unit rate of change here is = 50%

Part B

Equation to calculate the amount of money Greta will have after any number of weeks = ?

Money after 'x' number of weeks = $\text{Initial Deposit + x * Weekly Deposit}$

⇒ Money after 'x' number of weeks = $\text{100 + x * 50}$

Part C

Money Greta will have after 1 year= ?

In a year there are 52 weeks

So, putting x = 52 in the solution of Part B

⇒ Money after 52 weeks = $\text{100 + 52 * 50}$

⇒ Money after 52 weeks = $\text{100 + 2,600}$

⇒ Money after 52 weeks = 2,700

True or false: the product of a complex number and it’s conjugate is a real number

Sveta_85 [38]

$a,b\in\mathbb{R}\\
z=a+bi\\
\overline{z}=a-bi\\\\
z\cdot\overline{z}=(a+bi)(a-bi)=a^2+b^2$

If $a,b\in\mathbb{R}$ then also $(a^2+b^2)\in\mathbb{R}$ , so it's true.
