What is the slope of the line that passes through the points (14, 5) and (20, –4)? A. -3/2 B. -2/3 C. 2/3 D. 3/2

Lynna [10]

The slope of the line that passes through the points (14/5) and (20, -4), so you take y-y/x-x so you substitute the y's in for 5 and -4 and x in for 14 and 20.

5--4/ 14-20
9/-6
Then you make the fraction smaller!

The first missing quantity is force due to gravity, and it is 215.1 N.

The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.

<h3>Force between two masses</h3>

The force between two masses is determined by applying Newton's law of universal gravitation as shown below;

$F = \frac{GMm}{R^2}$

where;

M is mass of Earth = 5.97 x 10²⁴ kg
m is mass of the satellite
R is the distance between the satellite and the Earth
G is universal gravitation constant

<h3>First missing quantity</h3>

The first missing quantity is force due to gravity, and it is calculated as follows;

$F = \frac{(6.67 \times 10^{-11} ) \times (5.97 \times 10^{24}) \times (700)}{(36,000 \times 10^3)^2} \\\\F = 215.1 \ N$

<h3>Second missing quantity</h3>

The second missing quantity is distance between the statellite and the Earth,

$R^2 = \frac{GMm}{F} \\\\R^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})(1000)}{11,000} \\\\R^2 = 3.62 \times 10^{13}\\\\R = 6,000 \ km$

The Fibonacci sequence starts with the numbers 0,1,1,2,3,5,8 what are the next 3 terms in the sequence

shutvik [7]

It has been given that the Fibonacci sequence starts as 0, 1 , 1 , 2 , 3 , 5 , 8

We can see that every term is equal to the sum of the previous two terms

We already have 7 terms, so to determine the next three terms:

term 8 = t₈ = t₇ + t₆ = 8 + 5 = 13

term 9 = t₉ = t₈ + t₇ = 13 + 8 = 21

term 9 = t₁₀ = t₉ + t₈ = 21 + 13 = 34

Hence, the next three terms are 13, 21 and 34. So the correct option is B
