${\bold{\red{\huge{\mathbb{QUESTION}}}}}$

The semicircle shown at left has center X and diameter W Z. The radius XY of the semicircle has length 2. The chord Y Z has length 2. What is the area of the shaded sector formed by obtuse angle WXY?

$\bold{ \red{\star{\blue{GIVEN }}}}$

RADIUS = 2

CHORD = 2

RADIUS --> XY , XZ , WX

( BEZ THEY TOUCH CIRCUMFERENCE OF THE CIRCLES AFTER STARTING FROM CENTRE OF THE CIRCLE)

$\bold{\blue{\star{\red{TO \: \: FIND}}}}$

THE AREA OF THE SHADED SECTOR FORMED BY OBTUSE ANGLE WXY.

$\bold{ \green{ \star{ \orange{FORMULA \: USED}}}}$

AREA COVERED BY THE ANGLE IN A SEMI SPHERE

$AREA = ANGLE \: \: IN \: \: RADIAN \times RADIUS$

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

Total Area Of The Semi Sphere:-

$AREA = \pi \times radius \\ \\ AREA = \pi \times 2 = 2\pi$

Area Under Unshaded Part .

Given a triangle with each side 2 units.

This proves that it's is a equilateral triangle which means it's all angles r of 60° or π/3 Radian

So AREA :-

$AREA = \frac{\pi}{3} \times radius \\ \\ AREA = \frac{\pi}{3} \times 2 \\ \\ AREA = \frac{2\pi}{3}$

$\green{Now:- } \\ \green{ \: Area \: Under \: Unshaded \: Part }$

Total Area - Area Under Unshaded Part

$Area= 2\pi - \frac{2\pi}{3} \\ Area = \frac{6\pi - 2\pi}{3} \\ Area = \frac{4\pi}{3} \: \: ans$

Solve each question and check your solution <br> -2(3x-4)=4(x+3)+6

agasfer [191]

Answer:

x = -1

Step-by-step explanation:

-2(3x-4)=4(x+3)+6

Distribute

-6x +8 = 4x +12 +6

Combine like terms

-6x +8 = 4x+18

Add 6x to each side

-6x+6x +8 = 4x+6x +18

8 = 10x+18

Subtract 18 from each side

8-18 =10x+18-18

-10 = 10x

Divide each side by 10

-10/10 = 10x/10

-1 =x

HELP!!! I need help in simplifying this question.

kherson [118]

Answer: $x^{-4}=\frac{1}{x^{4}}$

Step-by-step explanation:

We have the following expression:

$(\sqrt[3]{x^{2}} \sqrt[6]{x^{4}})^{-3}$

Which can also be written as:

$(x^{\frac{2}{3}} x^{\frac{4}{6}})^{-3}$

Since we have exponents with the same base $x$ inside the parenthesis, we can sum both exponents:

$(x^{\frac{4}{3}})^{-3}$

Now, we have to multiply the exponent out of the parenthesis with the inner exponent and have the following result:

$x^{-4}=\frac{1}{x^{4}}$

a scatter plot is just plotting the x and y coordinates on the graph. x is horizontal (side to side) and y is vertical (up and down). the trend is just basically a line you guesstimate in the middle of the points that are scattered through the graph. describe it by saying whether it is positive or negative.
