The coordinates of the point P which divides the line segment AB made by the points A(-7,2) and B(9,-6) is  (x,y) = (5,-4)

Suppose that there is a line segment [tex]\overline{AB}[/tex]such that a point P(x,y) lying on that line segment [tex]\overline{AB}[/tex] divides the line segment  [tex]\overline{AB}[/tex] in m:n, then, the coordinates of the point P is given by:

[tex](x,y) = \left( \dfrac{mx_2 + nx_1}{m+n} , \dfrac{my_2 + ny_1}{m+n} \right)[/tex]

where we have:

We're given that:

Let the coordinate of P be (x,y), then we get the values of x and y as:

[tex](x,y) = \left( \dfrac{mx_2 + nx_1}{m+n} , \dfrac{my_2 + ny_1}{m+n} \right)\\\\(x,y) = \left( \dfrac{3(9) + 1(-7)}{3+1} , \dfrac{3(-6) + 1(2)}{3+1} \right)\\\\(x,y) = \left( \dfrac{20}{4} , \dfrac{-16}{4} \right) = (5,-4)[/tex]

Thus, the coordinates of the point P which divides the line segment AB made by the points A(-7,2) and B(9,-6) is  (x,y) = (5,-4)

Any Equation start with y = 7x + c is parallel to given equation.

To determine whether or not two lines are parallel, the formula for parallel lines is used. When we have the slopes of two lines that we want to compare, we can use the parallel line formula. The parallel lines' distances never change.

Given Equation

y = 7x + 5

and line k

line k is parallel  to equation y = 7x + 5

for parallel lines

The formula for determining whether two lines are parallel is as follows for any two lines with the equations y = m₁ x + c₁ and y = m₂x + c₂:

where m₁ and m₂ are the slopes of the two lines. m₁ = m₂.

given equation y = 7x + 5,

here m₁ = 7 and c₁ = 5

the line which is parallel to equation should be

y = 7x + c

where m₂ = m₁ = 7 and c₂ = c

Hence equation y = 7x +c is parallel to given equation.

The approximate x-coordinates of the points of intersection of the given curves are 0 & 1.76, and the volume of the solid when rotated about the x-axis is 3.15 cubic units

The equations are given as:

y = ∛2x - x²

y = x²/(x² + 1)

See attachment for the graph of the above curves (equation)

From the attached curve, we have the following points of intersection

(x,y) = (0,0) and (1.76,0.76)

Remove the y coordinates

x = 0 and 1.76

Hence, the approximate x-coordinates of the points of intersection of the given curves are 0 and 1.76

The volume of the solid is calculated using:

V = π(R² - r²)

Where R and r are the outer and the inner radii, respectively.

In this case;

R = ∛2x - x²

r = x²/(x² + 1)

Using a calculator, we have:

V = 3.15

Hence, the volume of the solid when rotated about the x-axis is 3.15 cubic units

Answer:

Step-by-step explanation:

The two given numbers both have the denominator 5,  Thus the quotient quickly reduces:

11 4/5 becomes 59/5 and 3 1/5 becomes 16/5.  Dividing the first expression by the second yields 59/16, which can't be reduced.

However, 59 = 48 + 11, so 59/16 = 48/16 + 11/16, which is approximately 3 1/2 (from either Answer B or Answer C).

The exact answer is 3 11/16; B and C are identical and are closer to 3 11/16 thn 3 or 4.

Using the binomial distribution, it is found that there is a 0.38 = 38% theoretical probability that all 6 bulbs will last for 4 months.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, we have that:

The probability that all 6 bulbs will last for 4 months is P(X = 6), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 6) = C_{6,6}.(0.85)^{6}.(0.15)^{0} \approx 0.38[/tex]

aight so monkey monkey is monkey so if u put monkey and monkey together u get happy baby monkey did i explain myself?????

Step-by-step explanation:

First of all, we need to find the slope. In order to find the slope, we'll use the following formula :

[tex]\boxed{\\\begin{minipage}{2cm}slope \\ $\displaystyle\frac{y2-y1}{x2-x1}$\end{minipage}}[/tex]

[tex]\boxed{\\\begin{minipage}{2cm}$\displaystyle\frac{-31-35}{-6-5}$ \\ \end{minipage}}[/tex]

[tex]\boxed{\\\begin{minipage}{2cm}$\displaystyle\frac{-77}{-11} \\ \end{minipage}}[/tex]

Which simplifies to :

[tex]\text{Slope = 7 }[/tex]

Now that we know the slope, finding the point-slope equation is a piece of cake.

Remember Point-Slope :

[tex]\text{y - y1 = m(x-x1)}[/tex]

We're told to use the first point (5, 35) in our equation, so we'll do just that.
