Answer:
3/5
Step-by-step explanation:
18/30 = 3/5
simplify.
Answer:
A. Rate of Change: 25/1
B. Initial Value: 100
C. Y=25x+100
D. After 6 months the cost is 250$
E. 475=25x+100
475=25x+100
375=25x
x=15
So E. is 15 months
Step-by-step explanation:
The amount of heat lost by the water is 1870 calories
Step-by-step explanation:
The amount of heat released by a substance is given by the equation

where
Q is the amount of heat lost
m is the mass of the substance
C is the specific heat capacity of the substance
is its change in temperature
In this problem, we have:
m = 85 g is the mass of water
is the specific heat capacity of water
is the change in temperature of the water
Substituting, we find

The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).
<h3>What is the vertex of a quadratic equation?</h3>
A quadratic equation is modeled by:

The vertex is given by:

In which:
In this problem, the function is given by:
y = 2x² + 25x + 3.
Hence the coefficients are a = 2, b = 25, c = 3, then the coordinates of the vertex are given as follows:
The coordinates of the turning point of the graph of the quadratic equation is given by: (-6.25, -75.13).
