What is the value of x? Round to the nearest tenth. Please Help

Elodia [21]

Answer:

Step-by-step explanation:

The segment 20.2 cm is the tangent. Therefore x and 20.2cm are perpendicular.

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=x,\ leg=20.2cm,\ hypotenuse=(14.7+x)cm$

Substitute:

$x^2+20.2^2=(14.7+x)^2$ <em>use (a + b)² = a² + 2ab + b²</em>

$x^2+408.04=14.7^2+(2)(14.7)(x)+x^2$ <em>subtract x² from both sides</em>

$408.04=216.09+29.4x$ <em>subtract 216.09 from both sides</em>

$191.95=29.4x$ <em>divide both sides by 29.4</em>

$x\approx6.5\ cm$

Create an expression that simplifies to sin x

Dimas [21]

Answer:

$2\cdot \sin 0.5x \cdot \cos 0.5x$

Step-by-step explanation:

Here is one example:

$2\cdot \sin 0.5x \cdot \cos 0.5x$

$\sin 0.5x \cdot \cos 0.5x + \cos 0.5x\cdot \sin 0.5x$

$\sin (0.5x + 0.5x)$

$\sin x$

Use compatible numbers to solve the problem 488 ÷ 62.A. 450 ÷ 50 = 9B. 434 ÷ 62 = 7C. 490 ÷ 70 = 7D. 480 ÷ 60 = 8

ipn [44]

Option D is correct. The required compatible number is 480 ÷ 60 = 8

Compatible numbers are numbers that have a close approximate to a given value

Given the expression 488 ÷ 62

The compatible number for 488 is 480

The compatible number for 62 is 60

Using these compatible numbers to solve the expression will give:

488 ÷ 62

= 480 ÷ 60

= 480/60

= 48/6

= 8

Hence the correct option will be 480 ÷ 60 = 8

Solve for x<br> -5(2x+1)-2x-2=17

inna [77]

-5(2x+1)-2x-2=17
first, distribute
-10x-5-2x-2=17
combine like terms
-12x-7=17
get the x alone, eliminate the constant
-12x=24
divide out the -12 to get the x alone.
x=-2

Given circle X with radius 5 units and chord AB with length 8 units, what is the

kvv77 [185]

Answer: The correct option is (B) 3.

Step-by-step explanation: We are given a circle X with radius 5 units and chord AB with length 8 units.

We are to find the length of segment XC that bisects chord.

We know that the line segment drawn from the center of a circle to the midpoint of a chord is perpendicular to the chord.

So, in the given circle X, the segment XC is perpendicular to chord AB. Then, triangle XCB will be a right angled triangle with hypotenuse XB.

Since XC bisects AB, so the length of BC will be

$BC=\dfrac{AB}{2}=\dfrac{8}{2}=4~\textup{units}.$

And, radius, XB = 5 units.

Using Pythagoras theorem in triangle XCB, we have

$XB^2=XC^2+BC^2\\\\\Rightarrow XC^2=XB^2-BC^2\\\\\Rightarrow XC^@=5^2-4^2\\\\\Rightarrow XC^2=9\\\\\Rightarrow XC^2=3^2\\\\\Rightarrow XC=3.$

Thus, the length of the segment XC is 3 units.

Option (B) is CORRECT.
