The quadrilateral ABCD has an area of 58 in2 and diagonal AC = 14.5 in. Find the length of diagonal BD if AC ⊥ BD.
diamong [38]
So the quadrilateral is a rhombus. RSM Is hard and etc...
Anyways if the area =58^{2} and we know that one diagonal is 14.5 inches and we know that the area of a rhombus is 
\frac{D^{1} * D^{2}}{2}   =
then we can do inverse operation and do
\frac{54}{14.5} = 4 
4 * 2 because of the inverse operation has to be done to get the right answer and then you get the length of diagonal 2 is 8 in

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
BabaBlast [244]

Answer:

C

Step-by-step explanation:

We want to solve the equation:

x^2+2x+7=0

Using the quadratic formula. The quadratic formula is given by:

\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

In this case, <em>a</em> = 1, <em>b</em> = 2, and <em>c</em> = 7.

Substitute:

\displaystyle x=\frac{-(2)\pm\sqrt{(2)^2-4(1)(7)}}{2(1)}

Evaluate:

\displaystyle x=\frac{-2\pm\sqrt{-24}}{2}

Simplify the square root:

\sqrt{-24}=\sqrt{4\cdot 6\cdot -1}=\sqrt{4}\cdot\sqrt{6}\cdot\sqrt{-1}=2i\sqrt{6}

Hence:

\displaystyle x=\frac{-2\pm2i\sqrt{6}}{2}

Simplify:

\displaystyle x=-1\pm i\sqrt{6}

Hence, our solutions are:

\displaystyle x=\left\{-1+i\sqrt{6}, -1-i\sqrt{6}\right\}

Our answer is C.

In ΔRST, the measure of ∠T=90°, TS = 65, SR = 97, and RT = 72. What ratio represents the cotangent of ∠S?
horrorfan [7]

Answer:

65/72

Step-by-step explanation:

Given that ∠T=90° then the triangle ΔRST is  a right angled triangle. Considering ∠S, RT is the opposite side, TS is the adjacent side and RS is the hypotenuse side. Using the notation

SOH CAH TOA

Tan ∠S = 72/65

Hence the cotangent of ∠S which is the inverse of the tangent will be

= 65/72
