ANSWER - $101.40
WORKING OUT
568 miles ÷ 21 miles = 27 (fill ups)
$1.02 ÷ 1000 mL = $0.00102 (per mL)
$0.00102 x 3790mL = $3.83 per gallon
$3.83 per gallon x 27 fill ups = $103.40 (rounded) $103.41
Answer:
Step-by-step explanation:
(qor)(x)=q(r(x))=q(5x+2)=(5x+2)²-3(5x+2)-4
first find (qor)(x) as explained above
then put x=0 to get (qor)(0)
Answer:
b = √45
Step-by-step explanation:
From the figure we get, There are two right angled triangle.
In large triangle 'b' is the base, height = 6 and hypotenuse = 9
<u>To find the value of b</u>
Hypotenuse² = Base² + Height²
Here,
9² = b² + 6²
b² = 9² - 6² = 81 - 36 = 45
Therefore, b = √45
Nice. We're not really told which is the right angle. We can tell from the squared distances:



We see
so B is the right angle.
That was preliminary and probably indicated in an associated figure.
Now we want the line through the midpoint of the legs, AB and BC, in standard form.
The midpoint of AB is the average of the coordinates of A and B:

The midpoint of BC is

The line through those points is




That's the answer. Let's check it.
Midpoint of AB is (-2,3), -2 + 8(3)=22 good.
Midpoint of BC is (2,5/2), 2+8(5/2)=22 good.
