Answer:
Step-by-step explanation:
Let's solve this using our formula for exponential functions:
where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):
. Anything raised to the power of 0 is 1, so that means that
a = 3. We will use that value along with the x and y from the second coordinate to solve for b:
. b to the first is just b, so our equation is
6 = 3b and
b = 2.
Our equation then is
, the third choice down.
Answer:

Step-by-step explanation:
Answer:
the answer is B
Step-by-step explanation:
6w + 5 - 3w + 7
<h3>i) collect like terms</h3>
= 6w - 3w + 5 + 7
= 3w + 5 + 7
<h3>ii) add the numbers</h3>
= 3 w + 5 + 7
= 3w + 12
Answer:
#2 is 512mm³
#3 is 120m³
Step-by-step explanation:
#2
8³ which # 8×8×8=512mm³
#3 v=bh
v=20×6
v=120m³
Answer:
the mean is 5
Step-by-step explanation:
because if you add all the numbers and divide by the number of digits you should get the equation 40/8= 5 and that´s the answer
