Answer:
C. 9
Step-by-step explanation:
Since the greatest factor that both fits in 81 and 36 is 9, the GCF is 9.
Answer:
7.62
Step-by-step explanation:
We can draw another point at (-3, -4) named C to get a right-angled triangle.
AC = 2 (by counting)
BC = 7 (by counting)
Using Pythagoras Theorem,
(nearest hundredth)
The second degree polynomial with leading coefficient of -2 and root 4 with multiplicity of 2 is:
<h3>
How to write the polynomial?</h3>
A polynomial of degree N, with the N roots {x₁, ..., xₙ} and a leading coefficient a is written as:
Here we know that the degree is 2, the only root is 4 (with a multiplicity of 2, this is equivalent to say that we have two roots at x = 4) and a leading coefficient equal to -2.
Then this polynomial is equal to:

X = time, minutes
y = length, inches
When x = 32 min, y = 11.2 in
When x = 32+18 = 50, y = 10.75 in
Assume that a linear relatioship exists between x and y.
In table form, the given data is
x, min: 32 50
y, in: 11.2 10.75
The slope is
m = (10.75 - 11.2)/(50 - 32) = -0.025
In point-slope form, the required equation is
When x = 3 hours = 180 minutes, obtain
y - 10.75 = -0.025*(180 - 50) = -3.25
y = -3.25 + 10.75 = 7.5 in
Answer: 7.5 inches
Answer: 4.5 hours
Step-by-step explanation:
First you put 60000 and change 2.5 hours into minutes then divide by that, inwhich you get 400. After getting 400 divide 108000 by 400 which equals 270, divide by 60 for hours.
