Answer:

63.36 years

Step-by-step explanation:

This is a compound interest problem and the following information has been provided;

Principal, P = 1200

Interest rate, r = 4%

Accumulated amount, A = 14400

We are required to determine the number of years for the principal to accumulate to the given amount. We use the compound interest formula;

[tex]A=P(1+r)^{n}[/tex]

We substitute the given values into the formula and solve for n;

[tex]14400=1200(1+\frac{4}{100})^{n}\\12=(1.04)^{n}\\[/tex]

The next step is to introduce natural logarithms;

[tex]ln12=nln(1.04)\\n=\frac{ln12}{ln1.04}\\n=63.36[/tex]

Thomas has invested $1,200 at a 4% interest rate. Using the formula for compound interest and solving for time, it will take approximately 29.1 years for his account balance to reach $14,400.

Thomas has invested an amount of $1,200 into an account with a 4% interest rate. This type of problem involves the use of the formula for compound interest. The general formula for compound interest is: A = P(1 + r/n)^(nt), where:

In this case, we assume the interest is compounded annually, so n = 1. We rearrange the formula to solve for t, giving us the formula t = log(A/P) / log(1 + r).

Substituting the given values into the formula, we get t = log(14400/1200) / log(1 + 0.04), which gives a result of approximately 29.1 years. So, it will take around 29.1 years for the account balance to reach $14,400.

Answer:

B. line segment

because without the point A it would be a ray

or without the arrow after point a it would be a line

The figure a(n) represents a line segment Option(B)

A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane.

In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and. taken to be at infinity.

A line segment is bounded by two distinct points on a line. A line has no endpoints and extends infinitely in both the direction but a line segment has two fixed or definite endpoints.

The given figure is a line segment as it has two end points a and b and also it is bounded by the similar two extended point .

Answer:

C, (x - 4)(x - 2)

Step-by-step explanation:

to factor x² - 6x + 8, you need to find 2 numbers that multiplied together are equal to 8 and added together that are equal to -6

we can already eliminate answers B and D, since B added together does not equal -6, and D multiplied together does not equal 8

we are left with choices A and C

in order to get a positive 8 through multiplication, we need either two positive numbers, or two negative numbers

to get a -6 through addition, we need negative numbers

lets test (x - 4)(x- 2) to see if this works in the equation, we can use FOIL to expand the equation and we get:

x² -4x - 2x + 8

x² -6x + 8

our answer would be C, (x-4)(x-2)

The factored form of x^2 - 6x + 8 is (x - 2)(x - 4), which is option c.

To factor the expression x^2-6x+8 into its factored form, we are looking for two binomials (x - a)(x - b) such that when multiplied out, the result will be our original quadratic expression. The factors need to multiply to give the constant term 8, and add up to give the middle term -6. Starting with the constant term, the pairs of factors of 8 are (1, 8), (2, 4), and (-2, -4). We need to find the pair that adds up to -6, which is (-2, -4).

So, the factored form of x^2-6x+8 is (x - 2)(x - 4), and the correct choice here is option c.) (x - 4)(x - 2).

Answer:

Work:

first you want to change 1/2 so the denominator is a 4

1/2 is equivalent to 2/4

now you have -1 1/4 + 2/4

then you want to get rid of the whole number and make -1 1/4 into a fraction

-1 is -4/4 so add that to the 1/4

now you have -5/4 + 2/4

you can add that now easily and get -3/4

[tex]\large\boxed{h>2\ \vee\ h<1\to h\in(-\infty,\ 1)\ \cup\ (2,\ \infty)}[/tex]

Step-by-step explanation:

[tex]|2h-3|>1\iff2h-3>1\ \vee\ 2h-3<-1\qquad\text{add 3 to both sides}\\\\2h>4\ \vee\ 2h<2\qquad\text{divide both sides by 2}\\\\h>2\ \vee\ h<1\to h\in(-\infty,\ 1)\ \cup\ (2,\ \infty)[/tex]

The solution of the absolute value inequality |2h-3| > 1 is h > 2 or h < 1. Two cases are considered based on whether the expression inside the absolute value is greater than 1 or less than -1.

To solve the inequality |2h-3| > 1, you need to consider two cases because an absolute value inequality represents two separate inequalities.

Case 1: The expression inside the absolute value (2h-3) is greater than 1. This gives us the inequality 2h - 3 > 1. Solving for h, we get h > 2.

Case 2: The expression inside the absolute value (2h-3) is less than -1. This gives us the inequality 2h - 3 < -1. Solving for h, we get h < 1.

Thus, the solution of the absolute value inequality is h > 2 or h < 1.

Three methods to solve the equation are Division as Repeated Subtraction,Using Fraction Division Formula,Using Decimal Conversion.

I'll approach this problem using three different methods:

Method 1: Division as Repeated Subtraction

Dividing [tex]\( \frac{1}{3} \)[/tex] by 5 means finding out how many times 5 can be subtracted from 1/3

[tex]\( \frac{1}{3} - 5 = - \frac{14}{3} \)[/tex]

So, you can subtract 5 from 1/3 approximately 0 times with a remainder of [tex]\( - \frac{14}{3} \).[/tex]

Method 2: Using Fraction Division Formula

To divide a fraction by a number, you can multiply the fraction by the reciprocal of the number.

[tex]\( \frac{1}{3} \div 5 = \frac{1}{3} \times \frac{1}{5} \)[/tex]

[tex]\( \frac{1}{3} \times \frac{1}{5} = \frac{1 \times 1}{3 \times 5} \)[/tex]

[tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \)[/tex]

So, [tex]\( \frac{1}{3} \div 5 = \frac{1}{15} \).[/tex]

Method 3: Using Decimal Conversion

Converting 1/3 to a decimal gives [tex]\( 0.3333... \)[/tex]

Then, dividing 0.333 by 5 gives:

[tex]\( 0.3333... \div 5 \approx 0.0667 \)[/tex]

So, [tex]\( \frac{1}{3} \div 5 \approx 0.0667 \).[/tex]

These are three different ways to solve the problem [tex]\( \frac{1}{3} \div 5 \).[/tex]

Answer: 2 pizzas with 2.50 left

Step-by-step explanation: First you subtract the 3.50 from the 20, that'll leave you with 16.50 and then from there you subtract 7 from it until you can't anymore

Division is a method of distributing a group of things into equal parts.

According to the given question, we have the following data:

So, first of all, we have to pay the delivery charge whether we are ordering a single or bulk. That's why we have to deduct that from the total Sebastian has.

$20 - $3.50 = $16.50

So, now Sebastian has $16.50.

Now, each pizza is for $7.

So, it's clear now that, Sebastian has to divide his total amount by the price of each pizza to get how many pizzas he can order.

Number of pizzas Sebastian can order = (Total amount Sebastian has / price of each pizza)

= ($16.50 / $7)

= 2.36

But wait how can he order a fraction of pizzas so we have to take 2 as our answer.

Therefore, Sebastian could order a total of 2 pizzas.

the diameter, d, must be 6

Step-by-step explanation:

Formula for circumference of a circle with diameter d is C = πd.  

If C = 6π = πd, then the diameter, d, must be 6.

Answer:

7,539.14

Step-by-step explanation:

To solve for area, square the radius (radius times radius) then multiply by 3.14.

A=pir^2

The diameter is 98mm

pi= 3.14

r= 49^2=

49 X49= 2,401

2,402 X 3,14= 7,539.14

Answer:

A = 7539.14 mm^2

Step-by-step explanation:

Area of a circle is given by

A = pi * r^2

We need to know the radius

r = d/2

r = 98/2

r = 49 mm

The radius is 49 mm and pi = 3.14

A = 3.14 * (49)^2

A = 7539.14 mm^2

solutions to f(x)=g(x) are x=-1 and x=8

Step-by-step explanation:

The minimum point of the parabola will be found at ...

x = -b/(2a) . . . . . where a, b, c are the coefficients of ax²+bx+c

For g(x) = x² -6x -7, the minimum will be at x=-(-6)/(2·1) = 3. The minimum value is ...

g(3) = 3² -6·3 -7 = -16

so the vertex (minimum point) you want to plot is (3, -16). Since the coefficient of x² is 1, there is no vertical scaling, so when the value of x differs from 3 by 1 unit, the value of g(x) will be 1² = 1 unit higher. That is, g(4) = -15, so (4, -15) is another point on the parabola.
