Based on the family the graph below belongs to, which equation could represent the graph ?
Firstly this looks like translated log function graph
y=logxlog1=0
As per graph the graph is pulled some inwards y axis but little bit
y=log2xUsually log x leaves y axis at -1 but here it leaves at +2
So
y axis is moved upwards (+3)

garden to 24 feet by 30 feet.
How much water would he expect to use on his new garden? Show all of your work and provide a brief explanation with your answer.
Answer:
60 gallons

so he enlarged it by three so it would be 24by30
because of that, you have to multiply 20g by 3 also
that gives you 60 gallons
The car you are taking is reliable and in good condition. The insurance is paid, the maintenance is up to date, and it gets about 27 miles to the gallon. The gas tank holds 18.5 gallons, and the low gas light will turn on when there are 2.5 gallons left in the tank. You have saved up $1,264

Oregon right now is $3.20 a gallon.
a. How much does it cost to fill up your gas tank?
b. How far can you travel on a tank of gas?
c. Write that as an equation.
Answer:

help? I can’t figure out this problem
Answer:
B
Step-by-step explanation:
Euler's formula tells you that ...
cos(θ) +sin(θ)·i ≡ e^(i·θ)
__
So, for θ = 90° (= π/2 radians), this is ...
cos(π/2) +sin(π/2)·i = 0 +i = i = e^(i·π/2) . . . . . matches choice B

1-x+6, x>3
Tx2 +6.x23
O D. y =
{-x+6, x<3
Answer:
b
Step-by-step explanation:
The function represented by the graph is
y = { x² + 6 , x < 3
-x + 6 , x ≥ 3}
What is a function ?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
According to the graph
When x < 3 then y = + 6
and, at x = 3 we get an open interval.
So, y = x² + 6 is valid for x < 3 not at x =3.
Also , y = -x + 6 is valid for x ≥ 3 and we get a close interval.
Thus, the function represented by the graph is
y = { x² + 6 , x < 3
-x + 6 , x ≥ 3}
