Answer:
(3,-7)
Step-by-step explanation:
Using the algebraic rule for Rx-axis
(x,y)---->(x,-y)
(3,7)--->(3,-7)
Answer:
103.96
Step-by-step explanation:
The answer is 939.44 - 835. 48
we can do like: 939.44 - 835. 48 = 103.96 ( 938 -835 = 103 and 144 - 48 = 96).
Have a good day
Answer:
The volume of the cylinder is 502.4cm³
Step-by-step explanation:
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 10cm
π = 3.14
r = radius = 4cm
v = (π * r²) * h
we replace the unknowns with the values we know
v = (3.14 * (4cm)²) * 10cm
v = (3.14 * 16cm²) * 10cm
v = 50.24cm² * 10cm
v = 502.4cm³
The volume of the cylinder is 502.4cm³
Answer:
12 and 13
Step-by-step explanation:
(a)
To evaluate f(g(2)), evaluate g(2) then use the value obtained to evaluate f(x)
g(2) = 2(2) - 1 = 4 - 1 = 3, then
f(3) = 3² + 3 = 9 + 3 = 12
--------------------------------------------
(b)
To evaluate g(f(2)), evaluate f(2) the use the value obtained to evaluate g(x)
f(2) = 2² + 3 = 4 + 3 = 7, then
g(7) = 2(7) - 1 = 14 - 1 = 13
Answer:
a = c because they are vertical angles. vertical angles are alway congruent because they are bascially the same shape. it's a rule.
