Answer:

The correct option is 1. The diagonals of a rhombus are always perpendicular.

Step-by-step explanation:

A quadrilateral is rhombus if the opposite sides are parallel, opposite acute and obtuse angles are equal, and four equal sides.

The line segment jointing the opposite vertices is known as diagonal.

According to the property of rhombus, the diagonals of a rhombus are perpendicular bisector of each other.

The diagonals of a rhombus are always perpendicular. Therefore the correct option is 1.

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.
aivan3 [116]

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}

In Jayden's case:

  • A(n)=$400
  • r=12%=0.12
  • n=5 years
  • k=12 Months

We want to determine the amount Jayden put in the savings account.

400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\

P=\$220.18

Jayden earned $220.18 from doing odd jobs.

Formula for the surface area of a cylinder, SA = 2ar2 + 2arh. Solve for h.
MakcuM [25]

Answer:

h=\frac{SA-2\pi r^2}{2\pi r}

Step-by-step explanation:

The formula for the surface area of a cylinder is:

SA=2\pi r^2+2\pi rh

And we want to solve for the height h.

First, subtract 2\pi r^2 from both sides. This yields:

2\pi rh=SA-2\pi r^2

Now, divide both sides by 2\pi r. This yields:

h=\frac{SA-2\pi r^2}{2\pi r}

And we're done!
