Answer:
Decay
since 0.292 is less than 1
% rate of decrease
1 - 0.292 = 0.708
70.8%
Answer: 0.04 miles
SOLUTION
Given,
Average daily distance of a garden = 0.05 mile.
Distance traveled on day 1 = 0.2 times as far as the average
distance
= 0.2 x 0.05 miles
= 0.01 miles
Distance traveled on day 2 = 0.6 times as far as the average
distance
= 0.6 x 0.05 miles
= 0.03 miles
Total distance traveled in two days
= Distance traveled on day 1 + Distance traveled on day 2
= 0.01 miles + 0.03 miles
= 0.04 miles
Answer:
B
Step-by-step explanation:
To order from least to greatest, convert each number into a decimal.
8/9 = 0.89
π/3 = 1.0467
1.75
√5 = 2.24
The order is 8/9, π/3, 1.75 and √5
What factors of 24 are multiples of 3?
3,6,12,24
Remember
a^2-b^2=(a-b)(a+b)
a.
ok so look at last bit
-9x^2+1
can be rearanged into
1-9x^2
look familiar?
1^2-(3x)^2
(1-3x)(1+3x) or
(1-3x)(3x+1)
we nowhave
(3x+1)(5x-4)-(x-12)(3x+1)+(1-3x)(3x+1)
factor out (3x+1)
(3x+1)(5x-4-(x-12)+1-3x)
(3x+1)(2x-3-x+12)
(3x+1)(x+9)
b.
easy
a^2-b^2=(a-b)(a+b)
(4x+5)^2-(2x-3)^2=
(4x+5-(2x-3))(4x+5+2x-3)=
(4x+5-2x+3)(6x+2)=
(2x+8)(6x+2)
we can factor out the 2 from each
(4)(x+2)(3x+1)
a(x)=(3x+1)(x+9)
b(x)=(4)(x+2)(3x+1)
