★ QUADRATIC RESOLUTION ★

Roots of the given equation will be imaginary because it's discriminant is less than 0 and hence it'll yield imaginary solutions

D < 0

b² - 4ac < 0

4² - 4 ( 5 ) < 0

16 - 20 < 0

-4 < 0

Hence it's character is stated above

Checking for discriminant :

D < 0

4 - 4 *5 < 0

Hence , the character of quadratic equation states that the solution will be imaginary

A women from England sneezed 978 days in a row. About how many weeks did sh sneeze in a row? What units of time do you need to c

Marizza181 [45]

Answer:

She sneezed for 138.286 weeks in a row. You need days of week to create a proper conversion.

Step-by-step explanation:

There are 7 days in a week. There are 978 days shown.

You can depict it as this:

978 = 7x; x is the amount of weeks.

Divide both sides by 7

138.285714 = x

Round to three decimals

x = 138.286

Seven times the smaller

Taya2010 [7]

Given:

Seven times the smaller of two consecutive even integers is the same as -300 minus 4 times the larger integer.

To find:

The integers .

Solution:

Let the smaller even integer be x.

So, larger even integer is x+2 because they are consecutive even integers.

Seven times the smaller integer = 7x

-300 minus 4 times the larger integer = -300-4(x+2)

Now,

$7x=-300-4(x+2)$

$7x=-300-4x-8$

$7x+4x=-308$

$11x=-308$

Divide both sides by 11.

$x=\dfrac{-308}{11}$

$x=-28$

So, the smaller even integer is -28.

$x+2=-28+2=-26$

So, the larger even integer is -26.

Harlamova29_29 [7]

Answer:

Approximately 62 gallons of water will be used by Lee County by the year 2025.

Step-by-step explanation:

The amount, in millions gallons of water, spent by Lee County, in t years after 2019, is given by the following equation:

$P(t) = P(0)(1 + r)^{t}$

In which P(0) is the amount spent on 2019 and r is the increse rate, as a decimal.

In the year 2019, Lee County used approximately 55 million gallons of water.

This means that $P(0) = 55$

Historical trends show that each year the water demand is increasing by a rate of approximately 2.1%.

This means that $r = 0.021$

$P(t) = P(0)(1 + r)^{t}$

$P(t) = 55(1 + 0.021)^{t}$

$P(t) = 55(1.021)^{t}$

Approximately how many million gallons of water will be used by Lee County by the year 2025?

2025 is 2025 - 2019 = 6 years after 2019. So this is P(6).

$P(t) = 55(1.021)^{t}$

$P(6) = 55(1.021)^{6}$

$P(6) = 62.3$

Rounded to the nearest millions

Approximately 62 gallons of water will be used by Lee County by the year 2025.
