Answer:
Standard form .
Step-by-step explanation:
Given : 0.002
To find : What is the standard form.
Solution : We have given 0.002
To convert it in to standard form
Remove decimal
0.002 = .
By exponent rule
.
Then ,
= .
Therefore, Standard form .
the measure of DEF?
The expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.
When the two tangent are drawn to a circle from an exterior point then according to this theorem-
The length of these two tangents is equal.
In the diagram below, DE and EF are tangent to o. In the diagram half of the difference of the arc GF and DF is equal to the angle of the measure of DEF. Thus,
Thus, the expression which gives the measure of DEF, in the diagram where, DE and Ef are tangent to circle o is 1/2(236-124) degrees.

Answer:
A
Step-by-step explanation:
∠DEF is a tangent- tangent angle and is measured as
∠DEF = ( arc GF - arc DF), that is
∠DEF = (236 - 124)° → A
The quadratic equation which has solutions x=8 and x=-1 is x² - 7x - 8 = 0.
To find the quadratic equation with solutions x=8 and x=-1, we can use the property that in a quadratic equation ax²+bx+c=0, the sum of the roots is equal to -b/a, and the product of the roots is equal to c/a.
As we know the solutions here are x=8 and x=-1, therefore: sum of roots = 8 + (-1) = 7. product of roots = 8 * -1 = -8. Assuming 'a' as 1 (for simplicity), our quadratic equation would be x² - 7x - 8 = 0. So this is the quadratic equation that has solutions x=8 and x=-1.
