Answer:

Step-by-step explanation:

Exponential regression means a function that best fits the graph, or data table.

If we were to replace x (the input) with 1, A and C are eliminated options since they both equal very low values.

D is also eliminated, if the input was 1 it would not equal relatively close, rather it would be 1000.7

<u>Let's check B:</u>

$f(x) = (1000)(0.7)^{x}$

$f(1) = (1000)(0.7)^{1}$

$f(1) = 700$

Letter B best fits the data table.

*at f(1) A, C, and D are eliminated, their outputs are far from the value for 707.

The next event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart. If there are 15 meters from the startin

inessss [21]

The race is 111.6 m long.

8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1

Add to this the distance to the first hurdle and the distance from the last hurdle:
86.1+15+10.5 = 111.6 m

Jackson used the process of completing the square to solve the equation 2x2−12x=−6.

Nikolay [14]

Answer:

$x=3-\sqrt{6},x=3+\sqrt{6}$

Step-by-step explanation:

we are given equation as

$2x^2-12x=-6$

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

$2(x^2-6x)=-3\times 2$

step-2:

Simplify it

$x^2-6x=-3$

step-3:

Add both sides 3^2

$x^2-6x+3^2=-3+3^2$

now, we can complete square

$(x-3)^2=6$

step-4:

Take sqrt both sides

$(x-3)=-\sqrt{6},(x-3)=\sqrt{6}$

step-5:

Add both sides by 3

we get

$x=3-\sqrt{6},x=3+\sqrt{6}$

Convert y - 3 = 1/3 (x - 6) to standard form.

MAXImum [283]

Y - 3 = 1/3(x - 6)
y - 3 = 1/3 x -2
y = 1/3 x - 2 + 3
y = 1/3 x - 1

Answer ⇒ y = 1/3 x - 1
