Answer:
4√10
Step-by-step explanation:
Hello!
Let's first simplify the radical.
We can do this by expanding the radical:
We need to pull out a perfect square factor to expand a radical and simplify it. In 45, we have 9 and 5 multiplied, and 9 is a perfect square.
Let's work with √45:
- √45 can be written as √9 * √5 (using the rule √ab = √a * √b)
- √9 simplifies to 3, so it is 3√5
Now we can simplify the operation in the parenthesis by combining like terms:
- 3√5 + √5
- √5 + √5 + √5 + √5
- 4√5
Now using the same rule as above, we can multiply the values:
Your solution is 4√10
(-8,1) im not sure but I think that this is the answe
Real distance of Earth from Sun . . . 93 million miles
= 1 AU (Astronomical Unit)
10 times farther . . . . . 930 million miles = 10 AU
Compare:
==> Saturn . . . 9.5 AU
==> Uranus. . 19.2 AU
If Earth were 10 times farther from the sun than we really are,
then our planet would be just barely past Saturn ... about 10%
of the way from Saturn to Uranus.
Answer:
vertex (-3,5) and another pt (-2,4)
Step-by-step explanation:
It is in vertex form so the vertex is (-3,5)...
Now just plug in a value for x say like -2...
f(-2)=-(-2+3)^2+5
f(-2)=-(1)^2+5
f(-2)=-1+5
f(-2)=4
So another point is (-2,4)
