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.

Write an equation that is perpendicular to y=4x- 10 and goes through the point (4,2)
Answers
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
i need help with 4 and 5 please
Answers
Answer:
C
Step-by-step explanation:
to find 4, you use the equation [tex]a^{2}+b^{2}=c^{2}[/tex] where the c= hypotenuse, which is the slant of the triangle. Then you width and length can by put as a and b. This gives you [tex]15^{2}+4^{2} = s^{2}[/tex]. Then you solve for s which end up being 15.5.

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

Find the value of r in the following diagram.
Answers
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.

Convert this equation to slope-intercept form:
25x + 10y = 1,000
Answers
Answer:
y = -2.5x +100
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
We need to solve for y
25x+ 10y =1000
Subtract 25x from each side
25x-25x+10y = -25x +1000
10y = -25x+1000
Divide each side by 10
10y/10 = -25x/10 +1000/10
y = -2.5x +100
Answer:
y = -2.5x + 100
Step-by-step explanation:
25x + 10y = 1,000
10y = -25x + 1000
y = -2.5x + 100

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.
What is trigonometry?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.

What is the area of the following parallelogram in square centimeters?
396 cm2
360 cm2
3.6 cm2
3.96 cm2
Answers
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

A group of 59 randomly selected students have a mean score of 29.5 with a standard

score, ", of all students taking the test?
Answers
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
