Step-by-step explanation:
Draw a picture. Seriously, this time you need to, so you can see that PS is the hypotenuse of a right triangle with legs of length 3 and 4 .
PS = √(3² + 4²) = 5
Perimeter = PQ + QR + RS + PS = 9 + 4 + 6 + 5 = 24 cm
Full term- 20” (50cm)
Normal range 18” to 22”
Answer:
B
Step-by-step explanation:
It is linear.
We can see the right side are multiples of 3. So the equation so the table is:
c = 3h
When h = 5 c = 15
c = 3h
c = 3*5
c = 15
When h = 12 c = 36
c = 3h
c = 3*12
c = 36
The constant rate of change between cost and time is 3.
Another way to solve is check for rate of change using 2 points on the chart.
Let's choose h = 5 c = 15 and h = 12 c = 36
The normal equation for rate of change is:
m = in this case we have h and c so:
h₁ = 5 h₂ = 12
c₁ = 15 c₂ = 36
So:
Now that we know it's 3 we use slope intercept form to find the equation.
y = mx + b ( m = 3) and we plug in a point to find b.
y = 3x + b h = 5 (x) c = 15 (y)
15 = 3(5) + b Solve for b.
15 = 15 + b Subtract 15 from each side.
15 - 15 = 15 - 15 + b
0 = b b is 0 showing our equation was correct.
y = 3x or c = 3h
