Answer:

  m^2 = 35/9

Step-by-step explanation:

The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.

  x^2 +9(mx +2)^2 = 1

  x^2 +9(m^2x^2 +4mx +4) = 1

  (9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms

__

Then the discriminant is ...

  (36m)^2 -4(9m^2 +1)(35)

We want it to be zero, so we have ...

  1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses

  36m^2 = 140 . . . . . . . . . . . . . . . add 140

  m^2 = 140/36 . . . . . . . . . . . . divide by 36

  m^2 = 35/9

Answer:

Small cartons used , x = 15

Large cartons used , y = 10

Step-by-step explanation:

Given - 1. On Carlos's uncle's farm, 525 eggs have been accommodated in small and large cartons at a rate of 3/2

            2. If 15 eggs were accommodated in the small cartons and 30 in the large cartons.

To find - How many small cartons and how many large cartons were used?

Solution -

Let

Small cartons used = x

Large cartons used = y

Now,

Given that,

Small and large cartons at a rate of 3/2

⇒[tex]\frac{x}{y} = \frac{3}{2}[/tex]

⇒x = [tex]\frac{3}{2} y[/tex]                      ............(1)

Now,

Given that,

Total eggs accommodated = 525

Also,

15 eggs were accommodated in the small cartons and 30 in the large cartons.

⇒15 x + 30 y = 525

Now,

put the value of x in the above equation, we get

15([tex]\frac{3}{2} y[/tex] ) + 30 y = 525

⇒[tex]\frac{45 + 60}{2} y = 525[/tex]

⇒[tex]\frac{105}{2} y = 525[/tex]

⇒y = [tex]525*\frac{2}{105}[/tex]

⇒y = 5(2) = 10

⇒y = 10

Now,

Put the value of y, we get

x =  [tex]\frac{3}{2} y[/tex]  = [tex]\frac{3}{2}(10)[/tex] = 3(5) = 15

∴ we get

x = 15

y = 10

So,

Small cartons used , x = 15

Large cartons used , y = 10

Answer:

B

Step-by-step explanation:

We want to find the equation of a line with a slope of 3 that includes the point (0, 5).

We can use the slope-intercept form, given by:

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

Where m is the slope and b is the y-intercept.

Notice that the given point (0, 5) is already the y-intercept. So, b = 5.

By substitution, we acquire:

[tex]y=3x+5[/tex]

Hence, our answer is B.

Answer:

B: y=3x+5

Step-by-step explanation:

the line crosses the y axis at point 5, the slope is 3

x [tex]\leq[/tex] -1

Step-by-step explanation:

Answer:

x < - 1

Step-by-step explanation:

Given

18 < - 3(4x - 2)

Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.

- 6 > 4x - 2 ( add 2 to both sides )

- 4 > 4x ( divide both sides by 4 )

- 1 > x , then

x < - 1

Answer:

  85 m

Step-by-step explanation:

The area is the product of length and width. This can be used to find the width.

Step-by-step explanation:

first, you use the pythagorean theorem to find the missing side of the original and big triangle.

[tex]20 {}^{2} + 15 {}^{2} [/tex]

next, you simplify these into actual numbers

[tex]400 + 225[/tex]

after, you add these numbers together and find the square root.

[tex]\sqrt{625} = 25[/tex]

you have the answer for AC. next you need to find BD. of you line up BC with BD, BC would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for BD- that's just me- but I'm not sure how to exactly find it.

The requried Measure of the BD and AC in the given question is 17.32 and 25 respectively.

The geometric mean theorem for a right triangle states that the length of the altitude (height) to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.

Here,
From the triangle, following the Geometric mean theorem,

BD = √[AB×BC]
BD = √[20×15]
BD = √17.32

Now,
Applying the Pythagorean theorem to find AC,
AC = √15² + 20²
AC = 25

Thus, the requried Measure of the BD AC in the given question is 17.32 and 25 respectively.
