Answer:

d=4 $\sqrt{5}$

Step-by-step explanation:

d= $\sqrt{(3-(-5)^{2} +(2-6)^{2}$

d= $\sqrt{(3+5)^{2} +(2-6)^{2} }$ \

d= $\sqrt{64+16}$

d= $\sqrt{80}$

d= $4\sqrt{5}$

Illusion [34]

Answer:

$s\geq 23$

Step-by-step explanation:

We are given that a student needs to make a square cardboard piece.

Perimeter of cardboard should be equal to atleast 92 inches

We have to find that which shows reasonable domain for f(s)

Let s be the side of square cardboard

We know that perimeter of square =f(s=) $4\times side$

Then, perimeter of cardboard= $4s$

$4s\geq 92$

Dividing by 4 on both sides

$s\geq 23$

Hence, the domain of function $[23,\infty)$

Therefore, option d is true.

Answer:d: $s\geq 23$

How to solve and why the answer is (A)

Amanda [17]

$\dfrac{1}{2}x^2+mx=5\\
\dfrac{1}{2}x^2+mx-5=0\\\\
\Delta=m^2-4\cdot\dfrac{1}{2}\cdot(-5)=m^2+10\\
\sqrt{\Delta}=\sqrt{m^2+10}\\\\
x=\dfrac{-m\pm\sqrt{m^2+10}}{2\cdot\dfrac{1}{2}}=-m\pm\sqrt{m^2+10}$

Answer:

x = 27/8

Step-by-step explanation:

We can write a ratio to solve

x 3

------- = ----------

x+9 11

Using cross products

x*11 = 3(x+9)

11x = 3x+27

Subtract 3x from each side

8x = 27

8x/8 = 27/8

x = 27/8
