Answer:

• We are gonna use the quotient rule

- u is (3√x + 2x)
- v is 4x²
- du/dx is 3/2√x
- dv/dx is 8x
• Therefore:

Answer:
x=-2/k
Step-by-step explanation:
To solve you need to make x on one side while the other variables or numbers on the other.
First, you need to move the 9 to the other side by subtracting 9 from both sides: kx+9-9=7-9
Simplify: kx=-2
Now you need to divide by k into both sides in order to eliminate the k on kx:
x=-2/k
Answer: x=-2/k
Hope this helps!
If we use similar triangles ( as shown in the attachment ) we will see that the line CM is also 1/4 *( yC-yD)= 1/4*(2+2) = 1/4*4 =1
Answer: y-value of that point is A)
y=1.
Step-by-step explanation:
5 divided by five-thirds can be written in the fractional form is as follows :

It can be also written as :

He has done calculations as follows :
3 x 5/3=3/1 x 5/3 = 15/3 or 5
Miko was wrong in the first step where he multiplied 3 by (5/3). It should be 5 multiplied by (3/5). He has done multiplication incorrectly.
Answer:
60 different possibilities
Step-by-step explanation:
Number of bikers = 5
Positions = first, second and third
First positions = all 5 riders can take the first spot = 5 possibilities
Second spot = position 1 has been filled hence number of possibilities = ( 5 - 1) = 4
Third spot = position 1 and 2 has been filled ; number of possibilities =. (5 - 2). = 3
Number of possible arrangements :
5 * 4 * 3 = 60 different possibilities
