How many real solutions does the equation have? K^2=-89

Mathematics
1 answer:
bonufazy [111]4 years ago
7 0

Answer:

0 real solutions

Step-by-step explanation:

This problem can be solved by simply looking at the sign in front of 89. Since it is a negative, nothing squared can equal it.

In other words, when a number is squared, the product will never be negative. This is because even when two negatives are multiplied by each other, the negatives cancel each other out.

Examples:

2^2 = 4

-2^2 = 4 (not -4)

The formula for estimating the number, N, of a certain product sold is N = 8800ln(7t + 9), where t is the number of years after
arsen [322]
To determine or predict the expected number of sales after 2 years, we substitute 2 to the t of the givne equation.
                           N = (8800)xln(7(2) + 9)
                                N = 27,592.34
Thus, it is expected that the number of sales after 2 years is 27,592 units.

Sybille makes and sells candles for her Possible Project business. Sybille sells multi-scented candles for $3 each and single-sc
trasher [3.6K]

Answer:

24 multi-scented candles

10 single-scented candles

Step-by-step explanation:

There was no question, so I am going to assume that you want to know how many of each type of candles were sold.

Let m = no. of multi-scented candles

     s = no. of single-scented candles

(1)      m + s = 34             (2)   3m + 2s = 92      

               s = 34 - m              3m + 2(34 - m) = 92

                                              3m + 68 - 2m = 92

                                                  m + 68 = 92

                                                           m = 24

              s = 34 - 24 = 10

A 14-ounce box of cereal sells for $2.10. What is the unit rate?
Ahat [919]

Answer:

The unit rate is equal to 0.15\frac{\$}{ounce}

Step-by-step explanation:

we know that

The unit rate is the ratio of two measurements in which the second term is equal to one

In this problem to find the unit rate, divide the total cost of cereal by the total weight of cereal

so

\frac{2.10}{14}\frac{\$}{ounces} =0.15\frac{\$}{ounce}

therefore

The unit rate is equal to 0.15\frac{\$}{ounce}
