If g(x) is a reflection of f(x) over the x axis, then g(x) = -1*f(x), which can be shortened to g(x) = -f(x). We stick a negative outside the entire f(x) function to flip the signs of each y coordinate. For example, if the point (1,2) was on f(x), then (1,-2) is on g(x).
So f(x) = 5(0.8)^x turns into g(x) = -5(0.8)^x
Answer: Choice B
Answer: D
So we want to find out how big all the sides are to find out if its less than 400
do in calc
2(13x5)+2(8x5)+2(13x8)=418
418>400
and its d because its talking about the surface area since we are trying to cover the surface in wrapping paper
<span>The question is asking us to find the complex number such that: ( 3 + 2 i ) * x = 17 + 7 i. We know that i^ 2 = - 1. x = ( 17 + 7 i ) / ( 3 + 2 i ) . We have to multiply the numerator and the denominator by ( 3 - 2 i ). Then: x = ( 17 + 7 i ) * ( 3 - 2 i ) / ( 9 - 4 i^2 ) = ( 51 - 34 i + 21 i - 14 i^2 ) / ( 9 + 4 ) = ( 51 + 14 - 13 i ) / 13 = ( 65 - 13 i ) / 13 = 65 / 13 - 13 i / 13 = 5 - i. Answer: The complex number is 5 - i. </span>
Answer:
6 steps forward and 6 steps backward
Explanation:
12 steps in total - 6 + 6 = 12
Okay I dislike improper fractions but the way to do this
see how many times the bottom number (denominator) goes into the top number (numerator)
4 can go into 15 3 times so 3 is your whole number
now you have 15-12=3 and that last three will be your next numerator
so your answer will be
3 3/4
