The given expression can be solved as -3/5.

The given expression is  [tex]\sqrt[3]{\frac{-27}{125} }[/tex].

Here, 27 and 125 can be written as

27 = 3×3×3 = 3³

125 = 5×5×5 = 5³

Now, [tex]\sqrt[3]{\frac{-3^3}{5^3} }= ({\frac{-3^3}{5^3})^{\frac{1}{3} }[/tex]

= -3/5

Therefore, the given expression can be solved as -3/5.

First Part:

The minimum value is -0.75

The maximum value is 0.75

Second Part:

The amplitude is 0.75

Third Part:

An equation for this function is y = 0.75cos(x)

The minimum value of the graph is -0.75 and maximum value is 0.75, amplitude is 0.75, and function for the graph is y = 0.75cosx.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a graph shown in the picture.

From the graph, we can see that:

The minimum value = -0.75

The maximum value = 0.75

The amplitude = 0.75

And the graph of the function:

y = 0.75cosx

Where y ∈ [-0.75, 0.75]

Thus, the minimum value of the graph is -0.75 and maximum value is 0.75, amplitude is 0.75, and function for the graph is y = 0.75cosx.

Step-by-step explanation:

The value of r is 3.75 from the diagram.

We have to find the value of r which is a radius.

ABC is a right angle triangle in the circle.

We find the value of r by using pythagoras theorem.

r²+9²=(6+r)²

r²+9²=36+12r+r²

9²=36+12r

81=36+12r

Subtract 36 from both sides:

81-36=12r

45=12r

Divide both sides by 12:

r=45/12

r=3.75

Hence, the value of r is 3.75.

Take the number of students and multiply by the percent

20 * 60 %

Put in decimal form

20 *.60

12

There are 12 girls

Answer: 12 Students are girls.

60% of 20 students is 12. Which means the 12 students in the class are girls.

The Exterior Angle Theorem states that basically ∠ACB and ∠ACD are supplementary, meaning they should equal 180 when added together. Since you know one side of the whole angle is 35, simply do 180-35, which equals 145°.

Answer:

3.6 cm²

Step-by-step explanation:

18 mm = 1.8 cm

A = 2cm×1.8cm = 3.6 cm²

Your answer would be the third option, 3.6 cm².

The equation for the area of a parallelogram is the same for the area of a rectangle, which is base multiplied by perpendicular height. Because all of the answers are given in cm², we should convert all lengths in mm to cm.

This means that 18mm because 1.8cm (by dividing by 10).

Now we just do 1.8 × 2 = 3.6cm²

Step-by-step explanation:

Answer:

y = (-1/4)x + 3

Step-by-step explanation:

The slope of our equation is 4, so to find the slope of the perpendicular equation, we have that:

m1 * m2 = -1

Where m1 is the slope of the first equation and m2 is the slope of the perpendicular equation.

So, we have that:

4 * m2 = -1

m2 = -1/4

So the second equation is y = (-1/4)x + b

If the second equation goes through the point (4,2), for x = 4 we have y = 2, then:

2 = (-1/4)*4 + b

2 = -1 + b

b = 3

So the perpendicular equation is:

y = (-1/4)x + 3

Answer:

Theoretical Probability

Step-by-step explanation:

The answer is Theoretical Probability

We want this expression to fall in one of the two cases:

[tex]\alpha ^ 0 = 1 = 1^\beta[/tex]

So, if the exponent is zero, the base can assume any value, because everything (expect zero) to the power of zero is one.

Similarly, if the base is 1, the exponent can be any number, becuase 1 raised to any exponent is still one.

If we are looking for the "zero exponent" strategy, we simply have to impose

[tex]x+1=0\iff x=-1[/tex]

In this case, the expression becomes [tex]16^0=1[/tex], so we avoided the [tex]0^0[/tex] case and we're good.

If we are looking for the "base equals one" strategy, we must impose

[tex]3x^2-8x+5 = 1 \iff 3x^2-8x+4=0 \iff x=\dfrac{2}{3}\lor x=2[/tex]

Answer:

x = -1, ⅔, 2

Step-by-step explanation:

3x² - 8x + 5

3x² - 3x - 5x + 5

3x(x - 1) - 5(x - 1)

(3x - 5)(x - 1)

[3x² - 8x + 5]^(x+1) = 1

The ourput is 1 when:

1) The power is 0

x + 1 = 0

x = -1

2) base is 1

3x² - 8x + 5 = 1

3x² - 8x + 4 = 0

3x² - 6x - 2x + 4 = 0

3x(x - 2) - 2(x - 2) = 0

(3x - 2)(x - 2) = 0

x = 2 , ⅔

Therefore, 3 solutions

x = -1, ⅔ , 2

Answer:

Yes, the dimensions will be 2x2

Step-by-step explanation:

When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same.

Ex. 2x3 by 3x2 or QxD by DxW

The dimensions of the result will depend on the outer numbers.

Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result  

Yes, you can multiply a 2x3 matrix by a 3x2 matrix. The result will be a 2x2 matrix because the number of rows in the first matrix and the number of columns in the second matrix define the dimensions of the product matrix.

Yes, it is possible to multiply a 2x3 matrix by a 3x2 matrix. When multiplying matrices, the number of columns in the first matrix must be the same as the number of rows in the second matrix. Therefore, in this case, where we have a 2x3 matrix and a 3x2 matrix, the 3 columns in the first matrix and the 3 rows in the second matrix make multiplication possible.

The resulting product from the multiplication of these two matrices will be a new matrix whose dimensions are determined by the number of rows in the first matrix and the number of columns in the second matrix. In this case, as the first matrix has 2 rows and the second matrix has 2 columns, the resulting matrix will have dimensions of 2x2.

By applying Pythagorean's theorem to right-angled triangle PQR, the length of segment PQ is equal to [tex]\sqrt{29}[/tex] units.

In Mathematics and Geometry, Pythagorean theorem is an Euclidean postulate that can be modeled or represented by the following mathematical equation:

[tex]c^2=a^2+b^2[/tex]

Where:

By applying Pythagorean's theorem to right-angled triangle PQR, the length of segment PQ can be calculated as follows;

[tex]PQ^2=QR^2+PR^2\\\\PQ^2=2^2+5^2\\\\PQ^2=4 + 25\\\\PQ=\sqrt{29}[/tex]units.

Answer:

[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]    

[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]    

And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence

Step-by-step explanation:

Information given

[tex]\bar X = 29.5[/tex] represent the sample mean

[tex]\mu[/tex] population mean  

s= 5.2 represent the sample standard deviation

n=59 represent the sample size  

Confidence interval

The confidence interval for the true mean is given by the following formula:

[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex]   (1)

The degrees of freedom are given by:

[tex]df=n-1=59-1=58[/tex]

The Confidence interval is 0.90 or 90%, the significance is [tex]\alpha=0.1[/tex] and [tex]\alpha/2 =0.05[/tex], and the critical value is [tex]t_{\alpha/2}=1.671[/tex]

Now we have everything in order to replace into formula (1):

[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]    

[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]    

And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence
