Answer:

-5.238- 10^{7}

or

Since the exponent of the scientific notation is positive, move the decimal point  6  places to the right.

1620000

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)

What is the rate of change and initial value for the linear relation that includes the points shown in the table?
Wittaler [7]

Answer:

Initial value 12, rate of change: -2

Step-by-step explanation:

Step 1

Find the rate of change

we know that

In a linear equation the rate of change is equal to the slope

The formula to calculate the slope between two points is equal to  

m=\frac{y2-y1}{x2-x1}  

we have

A(1,10)\ B(2,8)  

Substitute the values  

m=\frac{8-10}{2-1}

m=-2  ----> rate of change

Step 2

Find the initial value

The equation of  the line into slope-point form is equal to

y-y1=m(x-x1)

Substitute

y-10=-2(x-1)

y=-2x+2+10y=-2x+12

The initial value is the value of y when the value of x is equal to zero (is the y-intercept)

y=-2*0+12=12----> initial value

In the circle below, Ab and CD are chords intersecting at E if AE=5, BE,12, and CE=6, what is the length of DE
diamong [38]

Answer:

DE = 10

Step-by-step explanation:

Here, we want to find the value of DE

we use the intersecting chord principle

That will be;

CE * ED = AE * BE

we have;

6 * DE = 5 * 12

DE = (5 * 12)/6

DE = 5 * 2

DE = 10
