Determine the distance between -7 and 7.

1 answer:

6 0

It is D) 14 Units because it takes seven units to get from -7 to zero and 7 units to get from 0 to 7. there fore 7+7=14.

Paula leaned a 10 ft ladder against a building as shown below. if Paula wants the top of the ladder to reac

amm1812

The distance between the building and the base of the ladder is 5√3 feet.

Step-by-step explanation:

Consider a right angle triangle,

Hypotenuse = Paula leaned a 10 ft ladder against a building.
Height = the top of the ladder is exactly 5 feet up in the building.
Base = 'x' ft, distance between the building and the base of the ladder.

From the Pythagorean theorem,

Base, x = $\sqrt{hypotenuse^{2}-height^{2} }$

⇒ x = $\sqrt{10^{2} -5^{2} }$

⇒ x = $\sqrt{100-25}$

⇒ x = $\sqrt{75}$

⇒ x = 5√3

The distance between the building and the base of the ladder is 5√3 feet.

What does it mean to say we have a base ten system? Be specific. Use examples.

NeTakaya

Answer:

This means that the decimal system is responsible for representing quantities using ten different digits.

Step-by-step explanation:

This means that the decimal system is responsible for representing quantities using ten different digits: 0 (zero), 1 (one), 2 (two), 3 (three), 4 (four), 5 (five ), 6 (six), 7 (seven), 8 (eight) and 9 (nine).

The digits acquire their value according to the relative position they occupy. This position, in turn, depends on the base in question. It has the powers of the number ten as a base. Thus: 10 raised to 0 is equal to 1; 10 raised to 1 is equal to 10; 10 raised to 2 equals 100; etc.

The number 123, for example, has three figures. In the decimal system, it is constructed as follows, respecting the corresponding positions:

(1 x 10 raised to 2) + (2 x 10 raised to 1) + (3 x 10 raised to 0)

(1 x 100) + (2 x 10) + (3 x 1)

100 + 20 + 3

123

As you can see, from right to left, the first place corresponds to the unit (10 raised to 0), the second place corresponds to the ten (10 raised to 1) and the third place corresponds to the hundred (10 raised to 2 ).

Hope this helps!

Find the 110 term of the sequence -7, 3, 13, 23, ...

Evgesh-ka [11]

First, find the nth term
To do this, find the term to term difference...
A
-7 and 3 = 10
3 and 13 = 10
13 and 23 = 10

As the difference is 10, we now write out the 10 times table

10, 20, 30, 40

The next step is to work out how to get from the sequence to the 10x table
B
-7 - 10 = -17
3 - 20 = -17
13 - 30 = -17
23 - 40 = -17

Now use the answer from each section in the general formula
x = An + B
This could also be written as ?n + ?
Using our numbers, this becomes 10n - 17

Now use the formula to work out the 110th term
(10 x 110) - 17
1100 - 17 = 1083

Please help . From the equation, what is the value of the radius, r ? x2 + y2 = 144

ale4655 [162]

Answer:

should be 12 if the x and y are squared. If you meant 2x and 2y than 12 is incorrect.

Step-by-step explanation: 144=r^2.
