Answer:
7³
Step-by-step explanation:
when dividing exponents that have the same base, you leave the base as the original (so in this case 7) and subtract the exponents (in this case it would be 9-6). that will be your new base and exponent.
Answer:
OG = 8.7
Step-by-step explanation:
The angle a tangent makes with a radius at the point of tangency is a right angle. That means ΔOGH is a right triangle.
The tangents to a circle from an external point are congruent, so GH = GI = 6.3. Now we know the sides of the right triangle are of lengths 6 and 6.3. The hypotenuse, OG is found using the Pythagorean theorem.
OG² = OH² +GH²
OG² = 6² +6.3² = 75.69
OG = √75.69 = 8.7
The length of OG is 8.7 units.

<em>Additional comment</em>
You might recognize this triangle as a 0.3 multiple of the Pythagorean triple (20, 21, 29).
3*10^-1=3*0.1=0.3
800*0.3=240
the number in scientific notation is 2.4*10^2
2x - 1 = 9 - 14x
16x - 1= 9
16x = 10
x = 10/16
x= 5/8 is the answer
