You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

Supose that the half-life of a cesium is 30 years. If there were initially 1000g of the substance,

AveGali [126]

After 200 years, 9.84 grams of Cesium would remain.

Let N represent the amount of substance after t years

The half-life of a cesium is 30 years., hence, this can be represented by exponential function:

$N(t)=ab^t$

where a is the initial value and b is the multiplier.

There were initially 1000g of the substance

a) The exponential model for this situation is:

$N(t) =1000(\frac{1}{2} )^{\frac{1}{30} t}\\\\N(t) =1000(\frac{1}{2} )^{\frac{t}{30}$

b) After 200 years (t = 200), the amount of Cesium remaining is:

$N(200)=1000(\frac{1}{2} )^\frac{200}{30} \\\\N(200) = 9.84g$

Hence after 200 years, 9.84 grams of Cesium would remain

Plz help me with this!!!!

julia-pushkina [17]

Answer:

by the distance formula

the points are (2,2) and (-2,7)

and subtituting d=sqrt((2-(-2))^2+(2-7)^2)

which is equal to sqrt of 41

and it is equal to 6.40

What fraction is it after subtracting one from both numerator and denominator becomes 5/17

ruslelena [56]

Answer:

6/18

Step-by-step explanation:

To find the answer to that, you reverse the subtraction. Start with 5/17 and add 1 to both numerator and denominator. You get ...

$\dfrac{5+1}{17+1}=\boxed{\dfrac{6}{18}}$
