Answer:

the exact value is x =1/2 or x=0.5

your welcome!

The exact value is x = 1/2.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given an expression as;

[tex]27^{-1/3} = \frac{9^{1/4} }{3^{r + 1}}[/tex]

Now we can see that

27 = 3³

9 = 3²

Then the power are 3(-1/3) = -1

3(1/4) = 3/4

So we have;

[tex]3^{-1} = \frac{3^{2/4} }{3^{r + 1}}\\\\3^{-1} =3^{1/2 -r - 1} \\\\3^{-1} =3^{1 -2r - 2 /2}\\\\3^{-1} =3^{-2r - 1/2}[/tex]

So,

-2 = -2r - 1

-2r = -1

r = 1/2

Answer:

157 cm^2

Step-by-step explanation:

area = pi r^2 you need half so 1/2 (3.14) (10^2)= 1/2 (3.14)(100), 1/2 (314)=157

Answer:

option A

Step-by-step explanation:

Here we can see that , the dimensions of the prism ( cuboid ) is 3 × 5 × 6 . If a cuboid has dimensions of l × b × h , then its TSA is ,

⇒ TSA = 2(lb + bh + hl)

⇒ TSA = 2[ (3)(5)+(5)(6)+(6)(3) ]

⇒ TSA = 2 [ 15 + 30 + 18 ]

⇒ TSA = 15 + 15 + 30 + 30 + 18 + 18

Hence the option A is correct .

Answer

6ac−2b−2

Step-by-step explanation:

Let's simplify step-by-step.

4ac+3−2b+2ac−5

=4ac+3+−2b+2ac+−5

Combine Like Terms:

=4ac+3+−2b+2ac+−5

=(4ac+2ac)+(−2b)+(3+−5)

=6ac+−2b+−2

The answer is 4,800 square centimeters I believe... Try to check my answer just in case I'm wrong...

Answer:

To find the area break up the shapes:

The rectangle is A = bh which is 7*3 which is 21.

Triangle: A = 1/2(bh)

A=1/2(3*7)

A=1/2(21)

A=10.5

Now add up the areas:

21+10.5

=

31.5

The answer is 31.5 units.

Answer:

133°

Step-by-step explanation:

angles on a straight line = 180°

180 - 144 = 36°

angles in a triangle = 180°

36 + 31 = 67

180 - 67 = 113

answer = 113°

Answer:

Step-by-step explanation:

The area of triangle IJK is 999.8 square centimeters

The given parameters are:

[tex]\angle I = 120^o[/tex]

[tex]\angle J = 59^o[/tex]

[tex]i = 340cm[/tex]

Start by calculating the length of side j using the following sine ratio

[tex]\frac{i}{\sin(I)} = \frac{j}{\sin(J)}[/tex]

Make j the subject of the formula

[tex]j = \sin(J) \times \frac{i}{\sin(I)}[/tex]

Substitute known values

[tex]j = \sin(59) \times \frac{340}{\sin(120)}[/tex]

Evaluate the expression

[tex]j = 337[/tex]

Next, calculate angle K using the following sum of angles formula

[tex]\angle I + \angle J + \angle K =180[/tex]

Substitute known values

[tex]120 + 59 + \angle K =180[/tex]

[tex]179 + \angle K =180[/tex]

Subtract 179 from both sides

[tex]\angle K =1[/tex]

The area of the triangle is:

[tex]Area = \frac{1}{2} ij \times \sin(K)[/tex]

So, we have:

[tex]Area = \frac{1}{2} \times 340 \times 337 \times \sin(1)[/tex]

Evaluate

[tex]Area = 999.8[/tex]

Hence, the area of triangle IJK is 999.8 square centimeters

The phase shift is C/B=5/2

We have given that the equation of  the sine wave

[tex]f(x)=sinx\\G(x)=\frac{1}{3} sin(2x-5)+1[/tex]

The formula f(x)=A sin(Bx-C)+D

by comparing the g(x) above formula

Phase shift is C/B

C=5 and B=2

Therefore the phase shift is C/B=5/2

Mean Absolute Deviation = 5.3333

Step-by-step explanation:

Xmean = 85

MAD = (85 - 85) + (92 - 85) + (88 - 85) + (80 - 85) + (91 - 85) + (74 - 85) /6

         =(0) + (7) + (3) + (5) + (6) + (11) /6

Mean Absolute Deviation = 5.3333

Answer:

[tex]\lim_{x \to 0} =-\frac{1}{6}[/tex]

Step-by-step explanation:

The first step in evaluating a limit should be to plug in the number to see if you get a result

When you plug in 0 to all of the x's in the expression, you are left with the constants -1 on the top and 6 on the bottom of the fraction.

So there's no need to go any further, the limit as x approaches 0 is [tex]-\frac{1}{6}[/tex]

Answer:

-1/6

Step-by-step explanation:

To find the limit as x approaches 0 we can just plug in 0

for the numerator: 3*0+5*0-1 = -1

For the denominator: 4*0+2*0+6= 6

answer is just -1/6 or -.16666666666666666666667
