A watering can dispenses water at a rate of 0.15 gallon per minute. The original volume of water in the can was 5 gallons. Which

set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water?

The changing rate of the amount of water in the watering can is a constant rate of 0.15 gallon per minute. 

The initial volume of water in the can at time = 0 is 5 gallons

The function will be a linear function in the form of y=ax+b where 
y is the volume of water in the can after x minutes
a is the changing rate
b is the initial volume when time is 0

Substitute all the values into the form we have

y=0.15x+5

Which could be the measures for the three angles of an acute triangle?
Tema [17]
C, because they are all below 90, which is a right angle, and acute angle means less than 90 degree angle, and above 90 degree angle is an obtuse angle.
This is my knowledge, so I might be wrong, but, I am 90% sure I'm right.

Glad I could help, and good luck :)

Whats a constant and a variable and a coeffecient ?
OLga [1]
A constant is a number, or a letter that represents a number that
never changes.  From the time the problem starts until as long
as it lasts, its value is constant.

A variable is a letter that stands for a number that can change.

A coefficient is each of the items in a group of them that are all
multiplied together.

Example:  17x + 4y

That's an expression with two terms.
The terms are  '17x'  and  '4yz'.

In the first term:
'17' is the numerical coefficient.
'x' is the literal coefficient.

In the second term:
'4' is the numerical coefficient.
'y' and 'z' are both literal coefficients.

Lindsay is creating a bridge out of dried pasta and glue. In her plans, she sketches the graph to determine the lengths of the n
alexgriva [62]
From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.

Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
y=a(x-h)^2+k

Thus, the equation of the given graph in vertex form is given by
y=a(x-5)^2+8

Also, recall that the equation of a parabola with roots, p and q, is given by
y=a(x-p)(x-q)

Thus the equation of the given graph can be given by
y=a(x-1)(x-9)

To get the value of a, we equate both equations and solve as follows:
a(x-5)^2+8=a(x-1)(x-9) \\  \\ a(x^2-10x+25)+8=a(x^2-10x+9) \\  \\ ax^2-10ax+25a+8=ax^2-10ax+9a \\  \\ 25a-9a=-8 \\  \\ 16a=-8 \\  \\ a=- \frac{8}{16} =- \frac{1}{2}

Therefore, the <span>function that Lindsay used to create her design is
f(x)=-0.5(x-5)^2+8
