The circumference is the diameter times PI
The exact circumference would be 9PI cm
The approximate circumference would be 9 x 3.14 = 28.26 cm
Step-by-step explanation:
let equation be y = mx + b.
m = (9-5)/(3-1) = 2
sub (1, 5):
5 = 2(1) + b
b = 3
therefore the equation: y = 2x + 3

Answer:
Step-by-step explanation:
A)
f(s)=2s+25 and s(w)=25w
f(w)=2(25w)+25
f(w)=50w+25
B)
The ujits for the composite function are f=number of flowers and w=number of weeks.
C)
f(30)=50(30)+25
f(30)=1500+25
f(30)=1525
Answer:
y-6=-7(x-3)
Step-by-step explanation:
m=y2-y1/x2-x1
m=-8-6/5-3
m=-14/2
m=-7
y-y1=m(x-x1) point slope
To find the lengths of a right triangle, we can use what is called Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse.
13^2 + b^2 = 17^2
169 + b^2 = 289
b^2 = 120
b = 11.0 cm
The length of the other leg of the triangle is 11.0 cm (rounded).
Hope this helps!
