Answer: Choice B. p = 320(0.81)^t</h3>
Use the ^ symbol to indicate exponents. So for instance 4^2 = 4 squared.
A decrease of 19% means we have r = -0.19 and 1+r = 1+(-0.19) = 0.81 as the base of the exponent. A decrease of 19% means the population retains 81% each year.
From the order of operations, we do parens, then multiply/divide, then add/subtract, rewriting each step to keep everything clear:
(14) - 2 - (50 ⋅ 2) <span>⋅ 1 - 1
14 - 2 - 100 </span><span>⋅ 1 - 1 [parens are finished]
14 - 2 - 100 - 1 [multiplication is finished]
-- we do the subtraction left to right, but here are the steps:
12 - 100 - 1
-88 - 1
-89</span>
Answer:
use desmos and then search up slope intercept calc to solve a
Answer:
Opposite sides are congruent
Step-by-step explanation:
you can create equations -18 + 7x = 3x + 14 and 13y = 9 + 10y to solve for x and y to find the length of each side and whether they(the two pairs of opposite sides) are congruent or not
B is your answer because if you check each one in the calculator B is the same as the expression and also 2^8 makes up the first part and the second half makes up the .24
