Answer 2
Answer:

Final answer:

The recursive formula for the given geometric sequence is an = an-1/4. This formula describes how each term in the sequence is the previous term divided by 4. It is used to find any term in the sequence when the previous term is known.

Explanation:

The sequence 3,072, 768, 192, 48, 12, ... is a geometric sequence. This means that each term is the previous term multiplied by a constant ratio. In this sequence, each term is being divided, or multiplied, by 4. Hence, the formula - called recursive formula - for a geometric sequence that can be used to find the next term is an = an-1/4.

Here, an is the nth term you're trying to find, n is the term number, and an-1 is the previous term in the sequence.

So, for example, to find the 6th term in the sequence (where n=6), you would divide the 5th term (48) by 4, which yields the 6th term: 12.

What statement is true

CF is perpendicular to AE

Since those two triangles are congruent, all of their sides have to be equal as well as their angles. If CF was not equal to AE, then the two corresponding angles of the triangle which are also supplementary angles will not be congruent. The only pair of angle measures that is both supplementary and equal is 90 and 90. I hope this helps!

If you are using algebra tiles to factor a trinomial of the form ax2 + bx + c, when would you need to bring in zero pairs? Why?

Answers

If the value of c is negative, you would need zero pairs to model the factorization of the polynomial. The x-tiles on the board determine what the constants are in the factors. The product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. Opposite signs on the constants will result in a negative value for c when multiplying the factors.

When we have c in ax2 + bx + c as negative, the pairs will have to be zero to achieve the  factorization of the polynomial.

What are algebra tiles?

Algebra tiles are squares that help students to develop the manipulative skills that are required in algebraic problems.

When we have c in ax2 + bx + c as negative, the pairs will have to be zero to achieve the  factorization of the polynomial. The x-tiles on the board determine what the constants are in the factors.  Since we need opposite signs to show the  constants this will give us a negative value for c when multiplying the factors.

What is the standard form of this number 1.46e-6

Answers

Answer:

1.46e-6=0.00000146

Step-by-step explanation:

Given : Number 1.46e-6

To find : What is the standard form of this number ?

Solution :

We know that, The number given is in scientific form in which "e" represents the number of zeroes placed as decimal to the right.

So,e-6=10^(-6)

In standard form,

1.46e-6=1.46* 10^(-6)

1.46e-6=(1.46)/(1000000)

1.46e-6=0.00000146

Therefore, The standard form is1.46e-6=0.00000146

The number 1.46 * 10^(-6) in scientific notation can be written in standard form as 0.00000146

In scientific notation, a number is expressed as the product of a decimal number (between 1 and 10) and a power of 10.

In this case, 1.46 * 10^(-6) can be interpreted as follows:

1.46 is the decimal number, which is between 1 and 10.

e-6 indicates that we need to multiply 1.46 by 10 raised to the power of -6.

To convert it to standard form, perform the multiplication.

10 raised to the power of -6 is equal to 0.000001.

So, multiplying 1.46 by 0.000001 gives us 0.00000146.

Therefore, the standard form of the number 1.46 * 10^(-6) is 0.00000146.
