Answer:

AB = 1.4 or 7/5

Step-by-step explanation:

(Excuse my rambling but I wanted to be sure of myself)

AD = 2(5/2) = 5

AD is a diameter.

any triangle in a circle with the hypotenuse as the diameter is a right triangle.

Draw a line from point A to point C.

ΔACD is a right triangle.

Solve for ∠CAD:

sin CAD = 3/5 = 0.6000

∠CAD = 36.87°

arc CD = 2 x 36.87°  = 73.74°

arc BC = arc CD = 73.74°

arc DB = 147.48°

∠BAD = 1/2 (147.48°) = 73.74°

draw a line from point D to point B

ΔBAD is a right triangle.

cos 73.74° = AB/5

AB = 1.4

Of the following integers, which is the closest approximation to (2√+5√)2(2+5)2?A. 7B. 10C. 13D. 15E. 17
MAXImum [283]

Answer:

C. 13

Step-by-step explanation:

from on online source, the question should be placed as thus:

Of the following integers, which is the closest approximation to (√2 + √5)^2 ?

A. 7

B. 10

C. 13

D. 15

E. 17

This is known as Algebraic expression. So we have to expand to simplify further

using  this identity  th (a+b)^2 = a^2 + b^2 +2ab

(√2 + √5)^2 =

(√2 + √5)(√2 + √5)

................Expansion of the above

\sqrt{2}* \sqrt{2} +\sqrt{2}* \sqrt{5} +\sqrt{2} *\sqrt{5}+\sqrt{5} *\sqrt{5}

2 + 5 + 2√10

~ 2 +5 + 2(3)

C. 13

NEED ASAP plz. I will also mark brainiest! Don't just take points, I will report you.
PilotLPTM [1.2K]

Part A:

You may choose the two lines connecting the origin and points A and B, and choose the portion of the space between them.

The line between the origin and A is

y = 3x

We want everything below this line (line included), so the first inequality is

y \leq 3x

The line between the origin and B is

y = \dfrac{1}{3}x

We want everything above this line (line included), so the second inequality is

y \geq \dfrac{1}{3}x

Create a system with these two inequalities and you'll have an area including only points A and B

Part B:

To verify the solutions, we can plug the coordinates of A and B in this system and check that we get something true: the coordinates of point A are (1,3), while the coordinates of point B are (3,1). The system becomes:

A:\begin{cases}3 \leq 3\cdot 1\\3 \geq \frac{1}{3}\cdot 1\end{cases},\quad B:\begin{cases}1 \leq 3\cdot 3\\1 \geq \frac{1}{3}\cdot 3\end{cases}

Which means

A:\begin{cases}3 \leq 3\\3 \geq \frac{1}{3}\end{cases},\quad B:\begin{cases}1 \leq 9\\1 \geq 1\end{cases}

And these are all true. So, the system is satisfied, which means that the points belong to the shaded area.

Part C

If you draw the line, you'll see that the only points that lay below the line are B and C. In fact, if we plug the coordinates we have

B:\ 1

And this are both true. You can check the coordinates of all other points, and see that they won't satisfy the inequality y<3x-6
