Answer:

12.56

Step-by-step explanation:

How I remember the area formula of a circle is with the word PIZZA. Pizza are you know is a circle and I break down the word. PI= 3.14, ZZ= Z² (but in books and class they will use r², I'm replacing that r with a z), A= area.

Using my formula

PIZZA

Pi=3.14

ZZ= 2²=4

A= area

3.14*4=area

12.56=area

Answer:

$\sqrt[6]{2}$

Step-by-step explanation:

$\sqrt[4]{\sqrt[3]{2^2}} =((2^2)^\frac{1}{3})^\frac{1}{4}\\\\=(2^2)^\frac{1}{12}\\\\=2^\frac{2}{12}\\\\=2^\frac{1}{6}\\\\=\sqrt[6]{2}$

Two common names for streets are Second Street and Main Street, with 15,969 streets bearing one of these names. There are 365 m

Helga [31]

8167 streets are named Second Street and 7802 streets are named Main Street.

Step-by-step explanation:

Given,

Total streets = 15969

Let,

x be the number of streets named as Second Streets

y be the number of streets named as Main Streets

According to given statement;

x+y=15969 Eqn 1

x = y+365 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+365)+y=15969\\y+365+y=15969\\2y=15969-365\\2y=15604$

Dividing both sides by 2

$\frac{2y}{2}=\frac{15604}{2}\\y=7802$

Putting y=7802 in Eqn 2

$x=7802+365\\x=8167$

8167 streets are named Second Street and 7802 streets are named Main Street.

Kim is watching a space shuttle launch from an observation spot 2 miles away. Find the angle of elevation from Kim to the space

hammer [34]

Answer:

Step-by-step explanation:

Find the diagrammatic representation in the attachment given.

We can see that the diagram is a right angled triangle. To get the angle of elevation, we will use one of the trigonometry identity SOH, CAH, TOA.

Given the adjacent of the triangle to be 2miles (observation spot from the point of launch)and the opposite (side facing the elevation angle) as 2.1miles (the height), we will use TOA.

tan∅ = opposite/adjacent

tan∅ = 2.1/2

tan∅ = 1.05

∅ = tan⁻¹1.05

∅ = 46.4°

<em>Hence the angle of elevation from Kim to the space shuttle, which is at a height of 2.1 miles is approximately 46.4°</em>

How to solve -13=5(1 4m)-2m?

Paladinen [302]

First, you would multiply: -13 = 70m - 2m. Then, you subtract the like terms, which would be 70m - 2m: -13 = 68m. You are looking for what m is, so you would divide 68 on both sides: m = - 13 / 68. In math, people would usually like fractions more than decimals, but if you are looking for the decimal number, it would be m ≈ - 0.19.
