The multiplicative rate of change of the function .

here we have 1 and 2

2 and 2/5

2 and 2/25

4 and 2/125 .

so here in each every term it has been increased by the multiple 1/5 .

explanation:2/5*1/5=2/25.

option 1 is the correct answer.

Answer: first choice: 1/5

Explanation:

An important feature of exponential functions is that they have a constant multiplicative rate of change.

The multiplicative rate of change is the ratio between two consecutiive terms. This is because every term is obtained by multiplicating the previous term by such constant rate.

Hence, you find the multiplicative rate of change by dividing any term by the previous one.

Here is what you obtain in this case:

Second term / first term = (2/5) ÷ 2 = (2×1) ÷ (2×5) = 1/5

Third term / second term = (2/25) ÷ (2/5) = (2×5) ÷ (2×25) = 1/5

Fourt term / third term = (2/125) ÷ (2/25) = (2×25) ÷ (2×125) = 1/5

Hence, the multiplicative rate of change is the first choice: 1/5

8. The endpoints of ST are s(-3, 2) and t(5,8). Find the coordinates of the midpoint of ST. Then find ST. OA midpoint: (1,5); ST

Naya [18.7K]

Answer:

The mid point of ST is (1,5) and ST = 10 units

Step-by-step explanation:

It is given that,

S(-3,2) and T(5,8). We need to find the coordinates of the midpoint of ST and also ST.

Let (x,y) be the mid point of ST. Using mid-point formula we get :

$(x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

We have, x₁ = -3, x₂ = 5, y₁ = 2 and y₂ = 8

So,

$(x,y)=(\dfrac{-3+5}{2},\dfrac{2+8}{2})\\\\(x,y)=(1,5)$

(1,5) is the midpoint of ST.

Using distance formula to find ST as follows :

$ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\ST=\sqrt{(5-(-3))^2+(8-2)^2} \\\\ST=10\ \text{units}$

Hence, the mid point of ST is (1,5) and ST = 10 units.

Which ordered pair is a solution to this equation?

yarga [219]

Let's test each alternative :

2 x - 9 y = 38 ( 7,5 ) :

( 2 * 7 ) - ( 9 * 5 ) = 38

14 - 45 = 38

-31 ≠ 38 ( wrong )

( 4 , - 1 ) :

( 2 * 4 ) - ( 9 * ( - 1 ) = 38

8 + 9 = 38

17 ≠ 38 ( wrong )

( 3 , - 3 ) :

2 * ( 3 ) - ( 9 * ( - 3 ) = 38

6 + 27 = 38

33 ≠ 38 ( wrong )

( 1 , - 4 ) :

2* ( 1 ) - 9 * ( - 4 ) = 38

2 + 36 = 38

38 = 38 ( Correct alternative )

( 1 , - 4 ) is correct alternative
