  [tex]\lim_{x \to 64} (\frac{x+x^{\frac{1}{2} } +x^{\frac{1}{3} }-76}{x^{\frac{1}{2} } } } )[/tex]   =  0

Step-by-step explanation:

Explanation:-

Given

         [tex]\lim_{x \to 64} (\frac{x+x^{\frac{1}{2} } +x^{\frac{1}{3} }-76}{x^{\frac{1}{2} } } } )[/tex]

       =   [tex](\frac{64+(64)^{\frac{1}{2} } +(64)^{\frac{1}{3} }-76}{(64)^{\frac{1}{2} } } } )[/tex]

      =  [tex](\frac{64+(8^{2} )^{\frac{1}{2} } +(4^{3} )^{\frac{1}{3} }-76}{(8^{2} )^{\frac{1}{2} } } } )[/tex]

      =    [tex]\frac{64+8+4-76}{8} = \frac{0}{8} = 0[/tex]

Final answer:-

[tex]\lim_{x \to 64} (\frac{x+x^{\frac{1}{2} } +x^{\frac{1}{3} }-76}{x^{\frac{1}{2} } } } )[/tex]   =  0

Answer:

The answer is D!

Step-by-step explanation:

Answer:

The lines are neither parallel nor perpendicular.

Therefore, we conclude that the statement ''neither parallel nor perpendicular'' is the correct answer.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the line equations

5y – 6x = –15

y = x + 5

Analyzing the equation 5y – 6x = –15

Given the equation

5y – 6x = –15

writing in the slope-intercept form of the line equation

5y = 6x - 15

divide both sides by 5

[tex]y=\frac{6}{5}x-3[/tex]

comparing with the slope-intercept form y = mx+b of the line equation

Thus, the slope of the line 5y – 6x = –15 is:

m₁ = 6/5

Analyzing the equation y = x + 5

Given the equation

y = x + 5

comparing with the slope-intercept form y = mx+b of the line equation

Thus, the slope of the line y = x + 5 is:

m₂ = 1

Conclusion:

The slope of the line 5y – 6x = –15 is:

The slope of the line y = x + 5 is:

We know that when two lines are parallel, they have equal slopes

But  

m₁ ≠ m₂

6/5 ≠ 1

As the m₁ and m₂ are not equal.

Hence, the lines are NOT parallel.

We know that when two lines are parallel, the product of their slopes is -1.

Let us check the product of two slopes m₁ and m₂

m₁ × m₂ = 6/5 × 1

             = 6/5

As  

m₁ × m₂ ≠ -1

Thus, the lines are not perpendicular.

In a nutshell,

The lines are neither parallel nor perpendicular.

Therefore, we conclude that the statement ''neither parallel nor perpendicular'' is the correct answer.

Answer:

Answer:

7.2º

Step-by-step explanation:

all polygon's exterior angles measure 360º, so we just need to divide by 50 to get and individual exterior angle measure. 360/50=7.2º

The measure of an exterior angle of a regular 50-gon should be considered as the 7.2º.

Since we know that

All polygon's exterior angles should have the total of 360º,

So basically we divide 360 by 50 so that the measure of an exterior angle should be determined

i.e.

[tex]= 360\div 50[/tex]

= 7.2 degrees

Hence, The measure of an exterior angle of a regular 50-gon should be considered as the 7.2º.

Answer:

B. 24.3°

Step-by-step explanation:

Apply the sine rule to solve for x

Thus:

[tex] \frac{sin(x)}{8} = \frac{sin(112)}{18} [/tex]

[tex] \frac{sin(x)}{8} = \frac{sin(112)}{18} [/tex]

Multiply both sides by 8

[tex] sin(x)= \frac{sin(112)}{18}*8 [/tex]

[tex] sin(x) = 0.4121 [/tex]

[tex] x = sin^{-1}(0.4121} [/tex]

x = 24.3° (nearest tenth)

The number of small sized bowls on the counter = 68 bowls

The number of medium sized bowls on the counter = 82 bowls

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of small bowls on the counter be = x

Let the number of medium bowls on the counter be = y

The total number of bowls is = 150

So , the equation will be

x + y = 150   be equation (1)

The amount the small bowl can hold = 4 ounces

The amount the medium bowl can hold = 6 ounces

The total amount of all the bowls on the counter = 764 ounces

So , the equation will be

4x + 6y = 764   be equation (2)

Now , on simplifying the equation (1) and equation (2) , we get

Multiply equation (1) by 4 , we get

4x + 4y = 600   be equation (3)

Subtracting equation (3) from equation (2) , we get

2y = 164

Divide by 2 on both sides , we get

y = 82

Therefore the number of medium sized bowl is 82 bowls

Substituting the value of y in equation (1) , we get

x + y = 150

x + 82 = 150

Subtracting 82 on both sides , we get

x = 68

Therefore , the number of small sized bowl is 68 bowls

Hence ,

The number of small sized bowls on the counter = 68 bowls

The number of medium sized bowls on the counter = 82 bowls
