The logarithmic statement [tex]log_bx=log_bc \cdot log_cx[/tex]  is true.

Logarithm is a mathematical operator that is used to simplify the exponential equations .

The logarithm is exponentiation's opposite function in mathematics. This indicates that the base b of another fixed number, the logarithm of a given number x, is the exponent that must be raised in order to obtain the given number x.

The exponential equation logₓy=n is equivalent to xⁿ=y.

The properties of Logarithmic equations are:

Now the given expression is of the form: [tex]log_bx=log_bc \cdot log_cx[/tex]

We know that [tex]log_bc=\frac{log_nc}{log_nb}[/tex]  and  [tex]log_cx=\frac{log_cx}{log_nc}[/tex]

let n=[tex]log_bc=\frac{log_nc}{log_nb}[/tex]  and p=[tex]log_cx=\frac{log_cx}{log_nc}[/tex]

Now for the right side of the equation we have:

n×p

[tex]log_bc \cdot log_cx[/tex]

This can be written as:

[tex]or, \frac{log_nc}{log_nb}\cdot\frac{log_cx}{log_nc}\\or, \frac{log_cx}{log_nb}\\or, log_bx[/tex]

which is equivalent to the left side of the equation.

Hence the statement [tex]log_bx=log_bc \cdot log_cx[/tex] is true.

The difference of the weight is 1 kg 949 g.

The weight of the two items to find the difference are as follows:

Difference in mathematics is the result of subtracting one number from another.

Therefore, let's convert  the weight .

1000g = 1 kg

32 g =

cross multiply

weight = 32 / 1000

weight = 0.032 kg

1000g = 1 kg

83 g = ?

cross multiply

weight = 83 / 1000 = 0.083 kg

Therefore,

25 kg + 0.032 kg = 25.032 kg

23kg + 0.083 kg = 23.083 kg

Hence,

the difference of the weight = 25.032 kg - 23.083 kg

the difference of the weight = 1.949 kg

Hence,

the difference of the weight = 1 kg 949 g

  (ii) center: (-3, 6)

  (iii) A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)

  (iv) (x +3)²/100 +(y -6)²/51 = 1

Step-by-step explanation:

(ii) The center is the midpoint between the foci:

  center = ((-10, 6) +(4, 6))/2 = (-10+4, 6+6)/2

  center = (-3, 6)

__

(iii) The vertices are the center plus or minus the semi-major axis length in the x-direction: (-3±10, 6).

The semi-minor axis length is the root of the difference of squares of the semi-major axis and the center-focus distance:

  semi-minor axis = √(10² -7²)

  semi-minor axis = √51

So, the co-vertices are the center plus or minus this value in the y-direction: (-3, 6±√51)

Using the labeling in the drawing the various points are ...

  A(-3, 6-√51), B(7, 6), D(-3, 6+√51), H(-13, 6)

__

(iv) For center (h, k) and semi-axis lengths 'a' and 'b' the equation of an ellipse is ...

  (x -h)²/a² +(y -k)²/b² = 1

For the center and axes here, the equation is ...

  (x +3)²/100 +(y -6)²/51 = 1

Answer:

Step IV; Tommy must set the quadratic expression equal to 0 before factoring.

plz give brainlyest

It is found that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that the system of a linear equation and a quadratic equation.

2x – y = –1

x² – 5x – y = –7

Now Tommy had completed the following steps in his algebraic solution process but could not factor the resulting quadratic equation as;

x²  – 7x – 1,

Step I: y = 2x + 1

Step II: x²  – 5x – (2x + 1) = –7

Step III: x²  – 5x – 2x – 1 = –7

Step IV: x²  – 7x – 1 = –7

Therefore, we conclude that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.

Answer:

A: Yes, because the chance of rain on Monday and the chance of rain on Tuesday are independent.

Step-by-step explanation:

We are given;

chance of rain next week on Monday is 50%. Thus;

P(rain next Monday) = 0.5

chance it rains on Tuesday is 80%. Thus;

P(rain next Tuesday) = 0.8

From independent events, we can say that;

P(A and B) = P(A) × P(B)

A and B are independent events because the probability of A doesn't affect B as is the case for rain on Monday and Tuesday given.

Thus;

P(rain on Monday & tuesday next week) = 0.5 × 0.8 = 0.4

This can also be written as 40%

Correct answer is option A since both events are independent

Answer:

You chose the correct option on the picture

x = -4; x = 12

Step-by-step explanation:

You solve for x by simplifying both sides of the equation, then isolating the variable.

If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.

x + 4 = 0
x − 12 = 0

Set x + 4 equal to 0 and solve for x.

Set x+4 equal to 0.

x+4=0

Subtract 4 from both sides of the equation.

x = −4

Set x − 12 equal to 0 and solve for x.

Set x−12 equal to 0.

x−12=0

Add 12 to both sides of the equation.

x=12

The final solution is all the values that make (x+4)(x−12)=0 true.

x=−4,12
