What you need to know for this case is that the calculator is using the scientific notation in two different ways:

Way 1:

a * 10 ^ b

Way 2:

aeb

Where, in both cases:

a, b: they are real numbers.

Therefore, for the following number:

 1.89*10^{-12}

We have an equivalent way is:

1.89e-12

Answer:

1.89e-12

The e refers to the exponent to which the base 10 is elevated.

Answer:

1.89\times 10^{-12}=1.89e-12

Step-by-step explanation:

Given : A graphing calculator displays 1.89\times 10^{12} as 1.89e12.

To find : How do you think it would display 1.89\times 10^{-12}? What does the e stand for?

Solution :

In a graphing calculator 'e' stand for exponent of 10.

1.89\times 10^{12}=1.89e12

In 1.89\times 10^{-12} there is only negative sign difference.

So, 1.89\times 10^{-12}=1.89e-12

The ratio of boys to girls in a group is 3:1. If there are 52 more boys than girls, work out how many people there are in total.
UkoKoshka [18]

Answer: 104 (Good chance its wrong)

Step-by-step explanation: if the ratio is 3:1 then there's 3 times as much boys as girls. if there are 52 more boys then that means 52 is twice as much as the number of girls so if we divide is by 2 we get 26. if we add 26 with 52 we get 78 and if we divide 78 by 3 we get 26. so I believe there are 26 girls and 78 boys. 26+78=104

I believe 104 is the answer but there's a good chance i'm wrong.

Which are the solutions of x^2 = –11x + 4?
strojnjashka [21]

This is a quadratic equation, i.e. an equation involving a polynomial of degree 2. To solve them, you must rearrange them first, so that all terms are on the same side, so we get

x^2 + 11x - 4 = 0

i.e. now we're looking for the roots of the polynomial. To find them, we can use the following formula:

x_{1,2} = \frac{-b\pm\sqrt{b^2-4ac}}{2}

where x_{1,2} is a compact way to indicate both solutions x_1 and x_2, while a,b,c are the coefficients of the quadratic equation, i.e. we consider the polynomial ax^2+bx+c.

So, in your case, we have a=1,\ \ b=11,\ \ c=-4

Plug those values into the formula to get

x_{1,2} = \frac{-11\pm\sqrt{121+16}}{2} = \frac{-11\pm\sqrt{137}}{2}

So, the two solutions are

x_1 = \frac{-11+\sqrt{137}}{2}

x_2 = \frac{-11-\sqrt{137}}{2}
