Given that <span>Jim uses the function f(x) = 0.7x + 23 to determine the amount he charges for each used drone he sells, where x is the original value of the drone and that t</span><span>he function g(x) = 1.08x is used to determine the amount a customer pays for a drone at Jim’s store including 8% sales tax.
</span> The <span>function to determine the total amount a customer pays for a used drone at Jim’s store including 8% sales tax is given by
f(x) + g(x) = 0.7 + 23 + 1.08x = 1.78x + 23.

Answer:
The fourth law of exponents says that "any value other than zero brought to an exponent of zero is equal to one". ... However, zero to the zero gets an error with the calculator, thus any value other than zero brought to an exponent of zero is equal to one, this proves fourth law of exponents.
F(x) = 3x + 2
f(x + 3) = 3(x+3) + 2
f(x+3) = 3x + 9 + 2
f(x+3) = 3x + 11 (Answer)
Answer:
0.024
Step-by-step explanation:
Given,
Red marbles = 4,
Green marbles = 7,
Total marbles = 4 +7 = 11,
Ways of choosing 3 marbles =
Ways of choosing 3 red marble = 
Hence, the probability of 3 red marble = 


≈ 0.024
Answer:
B=34.2
C=105.8
c=12.0
Step-by-step explanation:
find B using the sine rule
(sin40÷8)=(sinB÷7)
rearrange
sin B= (sin40x7)÷8
sin B=0.562
make sure to use your calculator
then press shift sin to find B
B= 34.2°
to the nearest tenth means to 1 decimal place
sum of angles in a triangle is 180
so 180-(40+34.2)=105.8°=C
use sine rule again to find c
(sin105.8÷c)=(sin40÷8)
rearrange
c= (sin 105.8x8)÷sin40
c=12.0
