Answer:

x = -8, x = 8

Step-by-step explanation:

|x| = 8

The absolute value turns the negative value inside the positive.

When given an absolute value like this, there are two cases.

If the absolute value is equal to something greater than 0, it has two solutions. If less than 0, it has no solutions. If it is equal to 0 it has 1 solution.

Since 8 is greater than 0, there are two solutions.

On solution is the positive version, one is the negative

So:

-Chetan K

Note that:

This can lead to two solutions:

Answer:

  0.2776

Step-by-step explanation:

A suitable calculator can tell you the area with only the "work" of entering the numbers:

  normalcdf(0.59,10) = 0.2775953248

(From a TI-83)

The area of the shaded region is about 0.2776.

Additional comment

The area beyond 7 standard deviations from the mean is on the order of 1.3×10^-12, so "infinity" as a limit can be effectively replaced by any number more than 7 standard deviations from the mean. We have used 10 as a stand-in for "infinity", but 7 would do nicely in this context (above), where only 10 digits are displayed.

Answer:

X = -1

Step-by-step explanation:

Subtract 12 from both sides

Subtract 12 from 9 to get -3

Divide both sides by 3

Divide -3 by 3 to get -1

The solution to [tex]\sqrt{3x + 12} = 9[/tex] is x = 23 and it is not an extraneous solution

The equation is given as:

[tex]\sqrt{3x + 12} = 9[/tex]

Take the square of both sides

3x + 12 = 81

Subtract 12 from both sides

3x = 69

Divide through by 3

x = 23

Substitute x = 23 in [tex]\sqrt{3x + 12} = 9[/tex]

[tex]\sqrt{3 * 23 + 12} = 9[/tex]

Evaluate the sum and product

[tex]\sqrt{81} = 9[/tex]

The above equation is true

Hence, the solution to [tex]\sqrt{3x + 12} = 9[/tex] is x = 23 and it is not an extraneous solution

Answer:

294in²

Step-by-step explanation:

Let the width be x

Perimeter = 2(length+width)

98 = 2(6x + x)

49 = 6x + x

49 = 7x

7 = x

The width is 7 and the length is 7 x 6 = 42

Area = length × width

42 × 7 = 294in²

Answer: 45.1

Step-by-step explanation:

The area of the figure is about 45 square cm.

A triangle is a polygon with 3 sides.

Given the quadrilateral ABCD.

The sum of the interior angles of a triangle is 180°, therefore,

44° + 38° + m∠C = 180°

m∠C = 180° - 44° - 38°

m∠C = 98°

Now, using the sine law in triangle BDC, it follows:

sin44°/ BC = sin98°/10

BC = (10·sin44°)/ sin98°

BC ≈ 7

The area of a triangle is half the product of its two sides and the sine of the included angle, therefore, the area of triangle BDC is:
A₁ = (1/2)× 10×7× sin38°

A₁ = 21.5

Now, in triangle ABD,

cos55° = AD/10

AD = 10 cos55°

Similarly,

sin55° = AB/10

AB = 10sin 55°

Hence, the area of the triangle ABD is:

A₂ = (1/2) × (10 cos55°) ×(10sin 55°)

A₂ = 23.5

Therefore, the total area of the figure is:

A = A₁ + A₂

A = 21.5 + 23.5

A = 45.0

Hence, the area of the figure is about 45 square cm.

The minimum amount of fencing she can use is 126.5 ft.

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the length of the long side of pen and y represent the length of the small side of pen. Hence:

xy = 2000

x = 2000/y

The perimeter (P) is:

P = x + 2y

P = 2000/y + 2y

The minimum amount is at dP/dy = 0, hence:

dP / dy = 2 - 2000/y²

2 - 2000/y² = 0

2 = 2000/y²

y = 31.6 ft.

Also:

x(31.6) = 2000

x = 63.3

P = 63.3 + 2(31.6) = 126.5 ft.

Answer:

7.71

Step-by-step explanation:

First off, the diameter is 3 and we know that the radius is always half of that (1.5). Since this is a semi-circle, we aren't going to multiply by 2 but instead we are going to add the diameter afterwards. So, we are going to do 1.5x3.14 which equals to 4.71. This is the part where you add the diameter which is 3. So, after you add it, you should then get 7.71!

Answer:

Step-by-step explanation:

The decrease is found by multiplying the original amount by the percentage decrease:

  $6600 × 28.5% = $6600 × 0.285 = $1881

Jose's account decreased by $1881.

__

The remaining value is the original amount, less the amount of decrease.

  $6600 -1881 = $4719

At the end of last year, Jose had $4719 in his investment account.

Answer:

first you need to find the number-x

42% is equal to 0,42

( 100% .... 1

42% ..... y )

so 0,42 * x = 64,26 x = 64,26 / 0.42 = 153

so x = 153 is your number

then you have to calculate all % the same way:

10,5% equals to 0,105 ... 0,105 * 153 = 16,065

21% equals to 0,21 ... 0,21 * 153 = 32,13

63% ..96,39

84% ..128,52
