Which formula can be used to describe the sequence? , −4, −24, −144,...

Answers

-4 to -24 you have to multiply 6

-24 x 6 = -144

Formula

a(n) = -4x6(n-1)

Answer:

[tex]An= -4(6)^{n-1}[/tex]

Step-by-step explanation:

−4, −24, −144,...

There is no common difference

-24/-4= 6

-144/ -24= 6

common ratio = 6

when there is a common ratio then it is an Geometric sequence

[tex]An= a1(r)^{n-1}[/tex]

a1 is the first term = -4

r is the common ratio = 6

Formula becomes

[tex]An= -4(6)^{n-1}[/tex]

which one?

Answers

If it is referring to the number of solutions for the x value, then it would be one solution :)

The simplification 6x + 8 = 7x + 13 is one solution. The correct option is A.

What is one solution?

There is just one correct answer to some equations. There is only one value for the variable in these equations that causes the equation to be true.

If you solve an equation and the result is a variable equal to a number, the equation has just one solution. There is only ever one real number solution to a quadratic problem. A system is deemed consistent if it has at least one solution.

A consistent system is independent if it only has one solution. A consistent system is dependent if there are an endless number of possible solutions. Both equations show the same line on a graph when you plot the equations.

Therefore, the correct option is A, one solution.

Howard planted a tree in his front yard six months, one week, and two days ago. If today is August 13th, what day did Howard plant the tree in his yard?

A. February 4
B. February 13
C. February 20
D. February 22

Answers

For this to be easier, we know the date is February, since we are subtracting the 6 months. So let's start with February 13th, and subtract a week. One week is equal to 7 days, so 13-7= 6. We're now on February 6th, and we still have to subtract 2 days. 6-2=4, so we are at our date. A, Howard planted a tree in his front yard on February 4th.

In the figure, lines a, b, and c are parallel and m∠4=48° .

Drag and drop the correct angle measure for each angle.

Answers

m∠4=48°
m<1 = m∠4=48°
m<2 = 180 - 44 = 132
m<3 = m<2 = 132
m<5 = m∠4=48°

The values of each angle are:

∠1 = 48

∠2 = 132

∠3 = 132

∠5 = 48

We have,

∠4 = 48

∠4 and ∠5 are corresponding angles.

so,

∠5 = 48

Now,

∠3 and ∠4 make a straight angle.

So,

∠3 + ∠4 = 180

∠3 = 180 - 48

∠3 = 132

Now,

∠2 and ∠3 are alternate angles.

So,

∠2 = ∠3 = 132

Now,

∠1 and ∠2 make a straight angle.

So,

∠1 + ∠2 = 180

∠1 = 180 - 132

∠1 = 48

Thus,

∠1 = 48

∠2 = 132

∠3 = 132

∠5 = 48

What are the amounts of interest and maturity value of a loan for 150,000 at 6 1/2% simple interest for 3 years?

Answers

The formula for computing the amount of simple interest is:

I = Prt

Where P = principal amount of the loan

r = interest rate of the loan

t = duration of the loan

Substituting the amounts in the formula,

I = (150,000) (6.5%) (3)

= 29,250

To compute for the maturity value, you have to add the interest to the principal amount:

Maturity value = 150,000 + 29,250 = 179,250

Final answer:

To calculate the amount of interest and maturity value of a loan, use the formula: Interest = Principal × Rate × Time. In this case, the interest is $29,250 and the maturity value is $179,250.

Explanation:

To calculate the amount of interest and maturity value of a loan, we can use the formula:

Interest = Principal × Rate × Time

Maturity Value = Principal + Interest

In this case, the principal is $150,000, the rate is 6.5% (0.065 in decimal form), and the time is 3 years.

Step 1: Calculate the interest

Interest = $150,000 × 0.065 × 3 = $29,250

Step 2: Calculate the maturity value

Maturity Value = $150,000 + $29,250 = $179,250

Therefore, the amount of interest is $29,250 and the maturity value of the loan is $179,250.

Jason ate one third of a pizza for dinner, and his brother ate one sixth of the same pizza.What portion of the pizza was left over?

Answers

One third = 2/6
2/6 + 1/6 = 3/6 = 1/2
They ate half a pizza.
That leaves the other half as the remainder

Jason and his brother ate a total of one half of the pizza when their portions, one third and one sixth respectively, are combined. Therefore, one half of the pizza was left over.

To calculate this, we add the fractions of the pizza that were consumed together:

Jason's portion: 1/3
Brother's portion: 1/6

We find a common denominator, which is 6 in this case, and sum the fractions:

(2/6) + (1/6) = 3/6

After simplifying 3/6, which is one half, we subtract this from the whole pizza to find the portion that is left:

1 - 1/2 = 1/2

Therefore, one half of the pizza was left over after Jason and his brother had their portions.
