Answer:
158cm
Step-by-step explanation:
Martine had the height of 50cm when born.
Every year she grows at an average rate of 6cm
So the the first 18 years will be 6cm × 18 = 108cm
She will be 108cm + 50cm = 158cm tall by the time she turns 18 years
50cm + (6 × 18)cm
50cm + (6 × 18)cm50cm + 108cm
50cm + (6 × 18)cm50cm + 108cm158cm
General form for vertex form is:
y = a(x - h)² + k
Where the vertex is the point (h, k). We know this to be (5, -3), so we can substitute the values for h and k to get:
y = a(x - 5)² - 3
We then also have another point (6, 1) that gives us an x and y. Substitute those in to leave one unknown which we can solve for:
1 = a(6 - 5)² - 3
1 = a(1)² - 3
1 = a(1) - 3
1 = a - 3
4 = a
So the equation of this parabola in vertex form is:
y = 4(x - 5)² - 3

Answer:
The amount of flour Mrs.Stewart needs for 5 cups of shortening cups.
Step-by-step explanation:
Mrs.Stewart pie dough needs cups of shortening for cups of flour.
Now we assume that the shortening needed for cups of flour is cups.
Accordingly we can arrange the ratios.
So for one cup of shortening how many cups of flour is needed we have to use the unitary method:
Plugging the value of as it is number of cups of shortening Mrs.Stewart have used.
And multiplying both sides with .
Number of cups of flour needed when cups of shortenings are used .
So,
The amount of floor Mrs.Stewart needed for cups of shortening cups of floor.
