The graph equation
From the graph, we have:


The slope of the graph is:




So, the graph equation is:




In standard form, we have:

Answer:
y = (-1/5)x - 9
Step-by-step explanation:
15y = -3x - 135
Divide both sides by 15
y = (-1/5)x - 9
Answer:
area of this circle: 490.6 inch²
Step-by-step explanation:
area of circle: π(radius)²
Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in
using the formula:
3.14(12.5)²
490.625 inch²
490.6 inch²____rounded to nearest tenth.
Answer:
The diver will hit the water at 1.5 seconds
Step-by-step explanation:
Given

Required (Missing from the question)
When will the diver hit the water?
To do this, we simply solve for t
When the diver hits the water, the height is 0 (at that point)
So, substitute 0 for h in 

Divide both sides by -16




Split
or 
Solve for t
or 
But time (t) can not be negative.
So:

Hence, the diver will hit the water at 1.5 seconds
Answer:
a) 
b) -4.99
d) 1.9435
Step-by-step explanation:
We are given certain rule to identify number. We have to identify from the entries that can be interpreted as numbers.
a) 1.56e-9
This a number as there are no spaces, no comma, no units.
b) -4.99
This a number as there are no spaces, no comma, no units.
c) 40O0
This is not a number as 0 is substituted by O.
d) 1.9435
This a number as there are no spaces, no comma, no units.
e) 1.56 e-9
This is not a number as it contains a space.
f) $2.59
This is not a number as it contains a dollar sign.
g) 3.25E4
This is not a number as it contains alphabet.
h) 5,000
This is not a number as there is a comma in the given.
i) 1.23 inches
This is not a number as it contains a unit.
