In 75 minutes you travelled 30 kilometers, so the rate is 30/75=0.4km/minute
another way is to use the two points to find the slope: m=(30-0)/(75-0)=0.4
Please indicate exponentiation using " ^ " Thanks.
f(x)=x2+14x+40 => <span>f(x)=x^2+14x+40
Next, complete the square:
</span>f(x)=x^2+14x+ 49 - 49 +40 = (x+7)^2 - 9
Write this in the form y = (x+7)^2 - 9 or y + 9 = (x+7)^2
Comparing this result to y = a(x-h)^2 + k, we see that h = -7 and k=-9
In vertex form, the equation is y + 9 = (x+7)^2 and the vertex is at (-7, -9).
Answer:
Step-by-step explanation:
a right triangle is half of a rectangle and the area of a rectangle is
area of rectangle = length × width
Area of a triangle is one half times the length times the width
area of triangle = 1/2 × length × width
in this case
length is the number of the y units
width is the number of x axis unit
area of triangle = 1/2 × length × width
area of triangle = 1/2 × (y units) × (x units) you need to count and insert
the number of units into the
equation
area of triangle = 1/2 × (??? y units ) × (??? x units ) do the math yourself
and see if you get one of

Answer:
5
Step-by-step explanation:
Add the given numbers to the last recorded temp and see what is closest to 100 degrees.
95.5 + 6.5 = 101.5
95.5 + 6.6 = 102.1
95.5 + 5.5 = 101
95.5 + 5 = 100.5
So the closest to 100 degrees would be 5.
