d. $125, $135, $150, $130
Step-by-step explanation:
$125, $135, $150, $130
Range of the above set of numbers:
$150 - $125 = $25
Mean of numbers:
$125 + $135 + $150 + $130 = $540
540 ÷ 4 = $135
Answer:
Step-by-step explanation:
a. sin^-1(sin theta) = theta
(1/sin)(sin theta) = theta
<em>the sines cross out</em> theta = theta
b. cos(cos^-1x) = x
cos(x/cos) = x
<em>the cosines cross out </em>x = x
Answer:
20
Step-by-step explanation:
ƒ(x) = 3x² – 2
g(x) = 4x + 2
1. Add the functions
By definition,
(ƒ + g)(x) = ƒ(x) + g(x)
3x² - 2
<u> + 4x + 2
</u>
3x² + 4x
(ƒ + g)(x) = 3x² + 4x
2. Evaluate (ƒ + g)(2)
(ƒ + g)(2) = 3(2)² + 4(2) = 3(4) + 8 = 12 + 8 = 20
Step-by-step explanation:
1) 8=64÷r
8r=64
r = 64/8
r = 8
(8×8=64)
2)5p=30
p =30/5
p =6
3)56÷f =8
8f = 56
f =56/8=7
4)155/7
22.14...
aproximately 22 tables
5)185/8
=23.125
to serve each with a whole slice there should be 24 pizzas
