Answer:
3.
equation = 
Using:
or 
or
7^2 + 12^2 = c^2
49 + 144 = c^2
c^2 = 193
missing length = 13.9 inches
4. equation = 
Using:
or
24^2 + 32^2 = c^2
reduce to:
8 multiplied by everything:
3^2 + 4^2 = c^2
Since we know 3,4,5 is a Pythagorean triple, we can use this to find c.
Since c must be 5, we multiply by 8 since we divided by 8 earlier to get the 3,4,5 and get 40.
missing length = 40 inches
Answer:
19.08
Step-by-step explanation:
each gal = $2.12
gals filled = 9
9 x 2.12 = 19.08
Both exponential i.e 5 ^x
A is true, surprisingly.
B cannot be true, it alternates.(rule of indices negatives by positive exponent = positive, negative by negative , but -5 x -5 x -5 = + 5)
I'm only imaginging, but C must be right, since it increases exponentially, as opposed to D which only increases quadratically.
Answer:
<u>First find the slope using the formula </u>
m = (Y2 - y1)/(x2 - x1)
(x1, y1) = (0,6)
(x2, y2) = (2,10)
m = (10-6)/(2-0)
m = 4/2
m = 2
<u>Now we need the y-intercept or b</u>
y = mx + b
y = 2x + b
<u>Use one of the coordinates for x and y. It doesn't matter which you choose</u>
6 = 2(0) + b
6 = 0 + b
6 = b
<u>Now let's put it together for the equation :</u>
y = 2x + 6
