Answer:
f(x) = 5
Step-by-step explanation:
f(x) = 2x^2 - 3x+4
f(3) =2x^2 - 3x + 4
f(3) = 2(3)^2 - 3(3) + 4
f(3) = 18 - 13
f(x) = 5
Hope this helped :-)
$4.00 + $2.25* number of miles
$4.00 + $2.25* 8.7= $23.58
I got B as my answer for this
6 feet
20/15= 1.3 8/1.3=6.1 round to the nearest tenth and BOOM 6 feet
B. 25 Km. The measure of BC is 25 km.
The easiest way to solve this problem is using the cosine theorem c = √a²+b²-2ab*cos A.
BC = √AC²+AB²-2(AC)(AB)*cos A
BC = √(21km)²+(14km)²-2(21km)(14km)*cos 89°
BC = √441km²+196km²-588km²*(0.017)
BC =√637km²-10.26km²
BC = √636.74km²
BC = 25.03km ≅ 25
