What is the e at the end of a scientific number?

kherson [118]

Scientific notation is another way to write a number. In scientific notation, the letter E is used to mean "10 to the power of." For example, 1.314E+1 means 1.314 * 101 which is 13.14 .

A surveyor in a canyon takes measurements and draws the diagram shown.

Fiesta28 [93]

Answer:

$\approx 118.4$

Step-by-step explanation:

We know two sides and the angle between the sides, so we can use the Law of Cosines. Recall that the Law of Cosines states that:

$c^2=a^2+b^2-2abcos(C)$ , where a and b are the sides and C is the angle in between.

Let's substitute 115 for a, 178 for b, and 41 for Angle C.

Thus:

$c^2=115^2+178^2-2(115)(178)cos(41)$

$c^2=44909-40940cos(41)$

$c=\sqrt{44909-40940cos(41)}$

$c \approx 118. 4$

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β (see the figure) so that the cone

Aneli [31]

I don't know where the angle β is, so I will make the assumption that tanβ = h/r
$V = \frac{1}{3} \pi r^{2} h$

V volume = 60
r radius = 2
h = r tanβ

$tan \beta = \frac{3V }{ \pi r^{3} } = \frac{ 180}{25,1} = 7,17 \\ \\ \beta = 82$
