Answer:
The mean proportional of 6, and 24 will be 12
Step-by-step explanation:
We know that the Mean proportional of two
numbers, x, and y : [tex]\sqrt{xy}[/tex]
Therefore, the mean proportional of 6, and 24
[tex]=\sqrt{6\times 24}[/tex]
[tex]=\sqrt{144}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:144=12^2[/tex]
[tex]=\sqrt{12^2}[/tex]
[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]
[tex]\sqrt{12^2}=12[/tex]
[tex]=12[/tex]
Therefore, the mean proportional of 6, and 24 will be 12.

What is the rate of change of y with respect to x for 25x - 4y = 50 ?
Answer:
25/4Step-by-step explanation:
The change of y with respect to x is known as the slope of the line. The standard form of the equation is y = mx+c where m is the slope.
Given the equation 25x - 4y = 50, we need to make y the subject of the formula before we get the slope as shown;
25x - 4y = 50
-4y = -25x+50
Divide through b y -4
-4y/-4 = -25x/-4 + 50/-4
y = 25/4 x - 25/2
Comparing with y = mx+c
mx = 25/4 x
m = 25/4
Hence the rate of change of y with respect to x is 25/4
The rate of change of y with respect of x for the given equation is [tex]\frac{25}{4}[/tex].
Given the equation:
[tex]25x - 4y = 50[/tex]
The rate of change = the slope of the line
To determine the slope of 25x - 4y = 50, rewrite the equation in slope-intercept form. i.e. [tex]y = mx + b[/tex]Where, slope = mThus,[tex]25x - 4y = 50[/tex]
Add 25x to both sides of the equation[tex]25x -25x - 4y = - 25x + 50\\\\-4y = - 25x + 50[/tex]
Divide both sides by -4[tex]\frac{-4y}{-4} = \frac{-25x}{-4}+ \frac{50}{-4}\\\\y = \frac{25}{4}x - \frac{25}{2}[/tex]
Therefore, the rate of change of y with respect of x for the given equation is [tex]\frac{25}{4}[/tex].

What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture:
As we know, triangle is a polygon with three sides and three interior angles.
From the definition of the triangle, The triangle's interior angles add up to 180°
m∠MKL + m∠MLK + m∠KML = 180
Also, the sum of the two interior angles is equal to the exterior angle.
m∠KML + m∠MLK = m∠JKM

Forty of the staff of 85 teachers at a local intermediate school are certified in Cardio-Pulmonary Resuscitation (CPR). In 180 days of school, what would be the expected mean, variance and standard deviation?
Answer and Step-by-step explanation:
The computation is shown below;
Here we use the binomial distribution
p = 40 ÷ 85 = 0.47
q = 1 -0.47 = 0.53
n = 180
Now
mean [tex]\mu[/tex]
= np
= 180 × 0.47
= 84.6
The Variance is
= npq
= 180 × 0.47 × 0.53
= 44.84
And, Standard deviation
= √npq
= √44.84
= 6.69

a+b+c=m,a2+b2+c2=n,a3+b3=p3. If c=0 then prove that m3+2p3=3mn
Answer:
a + b + c = m
=> (a + b+ c)³= m³
⇔m³ = a³ + b³ +c³ + 3(a + b)(a + c)(c + b)
=> m³ + 2p³ = 3a³ + 3b³ + c³ + 3(a + b)(a + c)(b + c)
with c = 0 => m³ + 2p³ = 3a³ + 3b³ + 3ab(a + b)
have:
3mn = 3(a + b + c)(a² + b² + c²)
with c = 0
=> 3mn = 3(a + b)(a² + b²) = 3[a³ + ab² + ba² + b³]
= 3a³ + 3b³ + 3(a²b + ab²)
= 3a³ + 3b³ + 3ab(a + b)
= m³ + 2p³
=> 3mn = m³ + 2p³
Step-by-step explanation:
Given the conditions a + b + c = m, a² + b² + c² = n, and a³ + b³ + c³ = p, we are required to prove that if c = 0, then m³ + 2p³ = 3mn.
If c = 0, then the equations become a + b = m, a² + b² = n, and a³ + b³ = p.
Using the sum of cubes identity (a³ + b³ = (a + b)(a² - ab + b²)), we can rewrite the third equation as (a + b)(a²- ab + b²) = p.
Since a + b = m, we can substitute this value into the above equation: m(a² - ab + b²) = p.
Now, we'll square the first equation (a + b = m) to get a² + 2ab + b² = m². Rearranging, we find ab = (m² - n)/2.
Substituting this value of ab into the equation m(a² - ab + b²) = p, we get m(a² + b² - (m² - n)/2) = p.
Now, we know that a² + b² = n, so we can replace a² + b² in the equation: m(n - (m² - n)/2) = p.
Simplifying the equation further, we get
mn - (m³ - mn)/2 = p.
Finally, rearranging the equation, we find that
m³ + 2p³ = 3mn.
Thus, we have proved that if c = 0, then m³ + 2p³ = 3mn.

Answer:
Type: polynomial
degree: 3
leading coefficient: 8
Step-by-step explanation:
The given equation is: f(x) = -7x^2 + 8x^3 + 6 - 4x
To find the type, degree, and leading coefficient of the equation, the first thing we should do is rewrite the terms in decreasing order:
f(x) = 8x^3 - 7x^2 - 4x + 6
The term with the highest value is 8x^3. We can use this to determine the degree and the leading coefficient.
8 is the leading coefficient. The degree is 3.
To find the type of equation this is, we have to count how many terms there are. We can see that there are 4 terms in this equation, making this a polynomial.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Enter in the points:
[tex]m=\frac{-3--1}{-5-0}[/tex]
Simplify:
[tex]m=\frac{-2}{-5}[/tex]
[tex]m=\frac{2}{5}[/tex]
Now that we have slope we can just use one of the points given. Remember point-slope form:
