4. 15 000$ is invested in an account that yields 5% interest per year. After how many years will the account be worth 91 221.04$ if the interest is compounded annually.
​

Answer:

The pattern is that each number in the sequence is the previous number minus 1.5. For example, -5.5 is -4 minus 1.5, -7 is -5.5 minus 1.5, and so on.

Answer:

-1.5

Step-by-step explanation:

You take two of the variables in the pattern and subtract them with the second one being the minuend, and the first being the subtrahend.

For example we will use -4 and -5.5

(-5.5) - (-4) = -1.5

There is a negative sign present so it indicates subtraction towards the pattern.

Hence, the pattern change rate is -1.5

The rate of interest in one account whose investment is $2300 will be 3.21%.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Aniyah puts $2300 in one record and $1400 in a record paying 4 % higher interest. Toward the finish of one year, she had procured $130 in interest.

Let 'x' be the interest. Then the equation is given as,

(2300 × x × 1)/100 + (1400 × 4 × 1) / 100 = 130

Simplify the equation, then we have

23x + 56 = 130

23x = 74

x = 3.21%

The pace of revenue in one record whose speculation is $2300 will be 3.21%.

Answer:

Step-by-step explanation:

x² = 16² + 30²

x² = 256 + 900

x² = 1156

x = √1156

x = 34 cm

The inverse function is given by f⁻¹(x) = 1.06x.  2 euros is equivalent to 2.12 U.S. dollars. 4 euros is equivalent to 4.24 U.S. dollars

Given that: the two different currencies is modeled by a linear function f(x) = x/1.06

where, x = an amount in U.S. dollars and f(x) = the equivalent amount in euros

To find the inverse function f⁻¹(x). Let y = f(x):

y = x/1.06

x = 1.06y

Since x = f⁻¹(y) = 1.06y

Thus, f⁻¹(x) = 1.06x

Note: f⁻¹(x) will help you convert from euros to dollar

2 euros to dollars will be:

f⁻¹(x) = 1.06x

f⁻¹(2) = 1.06(2) = 2.12

Thus, 2 euros is equivalent to 2.12 U.S. dollars

4 euros to dollars will be:

f⁻¹(x) = 1.06x

f⁻¹(4) = 1.06(4) = 4.24

Answer:

x = 98

Step-by-step explanation:

Solve for x:

(x - 14)/7 = 12

Multiply both sides of (x - 14)/7 = 12 by 7:

(7 (x - 14))/7 = 7×12

(7 (x - 14))/7 = 7/7×(x - 14) = x - 14:

x - 14 = 7×12

7×12 = 84:

x - 14 = 84

Add 14 to both sides:

The shirt that Brian can iron in a minute is 5/81 shirts.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In this case, when we have a simple fraction, the numerator as well as the denominator are both integers. On the other hand, a fraction appears in the numerator or the denominator of a complex fraction.

Here, Brian irons 2/9 of his shirt in 3 3/5 minutes and it was stated that he irons at a constant speed

Therefore, to calculate the shirt he iron in a minute will go thus:

Here, set up a proportion (shirt ironed/minutes = shirt ironed/minutes). This will be illustrated as:

= 2/9 ÷ 3 3/5

= 2/9 ÷ 18/5

= 2/9 × 5/18

= 10 / 162

= 5 /81

If the probability that a hurricane will make landfall in Florida is 49%, then the probability that a hurricane will not make landfall in Florida is 51%

The probability that a hurricane will make landfall in Florida = 49%

The probability is the ratio of number of favorable outcomes to the total number of outcomes

The equation of probability will be

Probability = Number of favorable outcomes / Total number of outcomes

Given that

The probability that a hurricane will make landfall in Florida  = 49%

The probability that a hurricane will not make landfall in Florida = 1 - The probability that a hurricane will make landfall in Florida

   The middle term is,  -n  its coefficient is  -1 .

   The last term, "the constant", is  -24

Step 1: Multiply the coefficient of the first term by the constant   3 • -24 = -72

Step 2: Find two factors of  -72  whose sum equals the coefficient of the middle term, which is   -1 .

      -72    +    1    =    -71

     -36    +    2    =    -34

     -24    +    3    =    -21

     -18    +    4    =    -14

     -12    +    6    =    -6
