Answer:
$64.3
Step-by-step explanation:
Given the following
Total distance = 900miles
Rate per gallon = 21miles per gallon
rate = distance/time
Get the number of gallons used;
Number of gallons used = 900/21
Number of gallons = 42.857gallons
If coost of 1 gallon is $1.50
42.857gallons will cost 42.857 * 1.50
42.857gallons will cost $64.3
Hence he should budget $64.3 for the trip
It makes your life easier.One way is by just adding a 0 after the number.
Ex 2*10 is 20 see what I mean.
Answer:
use a calculator
Step-by-step explanation:
also if this is easier change 1/2 and 1/3 to 0.5 and 0.3 where it would be 8.5 x 3.3
Answer: r=C/2π
Step-by-step explanation:
Circumference= 2πr
C=2πr
Divide both side by 2π
C/2π = 2πr/2π
r = C/2π
Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.
