The solution is 2sqrt77/77. You just fill in 2/3 for the x's. When you do that, you do that you get (2/3)/sqrt(9-[2/3]^2) which, simplified, is (2/3)/sqrt(9-[4/9]). Now use the common denominator under the radical of 9 to get (2/3)/sqrt([81-4]\9). Simplifying even further gives you (2/3)/([sqrt(77)]/3). Now do that division by multiplying 2/3 by the reciprocal of ([sqrt(77)]/3) to get 2/sqrt77. I rationalized the denominator to get that result up there.
Answer:
f = 1
Step-by-step explanation:
-f + 2 + 4f = 8 - 3f
-f + 4f + 3f = 8 - 2
6f = 6
f = 6/6
f = 1
Hope it helps!!
Answer:
14
Step-by-step explanation:
Arithmetic expressions are best evaluated using a reliable calculator. The Google calculator always follows the Order of Operations, so can give you a good answer to such questions.
(1/4)^-2 - (5^0)(2)(1^-1)
= 16 - (1)(2)(1) . . . . evaluate the exponents first
= 16 -2 . . . . . . . . . evaluate the product next
= 14 . . . . . . . . . . . finally, evaluate the sum
___
The rule of exponents is ...
a^-b = 1/(a^b)
Answer:
$4720
Step-by-step explanation:
Simple Interest
A=P(1+in)
A- Accumulated Amount
P- Principal Amount
i- Interest (÷100)
n- Number Of Years
A=P(1+in)
A=4000(1+0.06×3)
A=4000(1.18)
.°.A=$4720
