Math symbols were invented for a reason. They help communicate your intent. Here, it looks like you may intend
... f(x) = a(2^x)
When x=0, this will have the value "a". When x=1, this will have the value a^2. The appropriate selection is
... f(0) = 3 when a = 3
Answer:
Rational
Step-by-step explanation:
Two broad categories of Real Numbers is:
- Rational Numbers
- Irrational Numbers
Rational numbers are those which can be written in the form of a fraction. When written in form of a decimal, these numbers terminate after few decimals or have a pattern that runs throughout the decimals.
Irrational numbers cannot be written in form of fractions. When written in the form of a decimal numbers, these numbers do not terminate(end) and do not show any pattern.
So, from the above discussion, we can conclude that the answer in the blank will be Rational. Fractions or decimals that stop are known as Rational numbers.
Answer:
16.67
Step-by-step explanation:
Step 1: We make the assumption that 20 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=20.
Step 4: In the same vein.
Step 5: This gives us a pair of simple equations
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
Step 7: Taking the inverse (or reciprocal) of both sides yields
Evaluate 3x for x = −2, x = 1, and x = 3. Question 18 options: A) 1∕3, 0, 9 B) 1∕9, 3, 27 C) 9, 3, 27 D) 1∕9, 9, 27
