Answer:
The range of the function is the set of all possible values that function can take. Both given functions
y=\left(\dfrac{4}{5}\right)^xy=(
5
4
)
x
and y=\left(\dfrac{4}{5}\right)^x+6y=(
5
4
)
x
+6
are exponential functions with base \dfrac{4}{5}.
5
4
.
The graphs of these function you can see in attached diagram.
The range of the function y=\left(\dfrac{4}{5}\right)^xy=(
5
4
)
x
is (0,\infty).(0,∞).
The range of the function y=\left(\dfrac{4}{5}\right)^x+6y=(
5
4
)
x
+6 (this function is translated function y=\left(\dfrac{4}{5}\right)^xy=(
5
4
)
x
6 units up) is (6,\infty).(6,∞).
Yes, all equilateral triangles have to be acute because to have equal sides you need equal angles.
Answer:
Number of coins that are not nickels = 55 coins
66 = 55 + n
number of nickels in the jar = 11
Step-by-step explanation:
Pennies = 17
Dimes = 12
Quarters = 26
Nickels = n
Total coins = 66
How many of the coins are not nickels?
= Pennies + Dimes + Quarters
= 17 + 12 + 26
= 55 coins
Number of coins that are not nickels = 55 coins
what equation could you use to find n?
Total coins = Pennies + Dimes + Quarters + nickels
66 = 17 + 12 + 26 + n
66 = 55 + n
n = 66 - 55
n = 11
number of nickels in the jar = 11
