Vertex form should be : y = (x+1)^2 - 2, where the vertex is (-1,-2)
Answer:
9 months
Step-by-step explanation:200+30m=470
30m=270
m=9
He will pay for 9 months
So they're proportional.
This means that the 2 triangles are exactly the same BUT the right one is smaller than the other, so all measurements are smaller too.
So to find the distance, you need to find the scale factor.
Think of it like this: 82m becomes 73.8m, and 92m becomes 82.8m.
Find the scale factor by finding the ratio.
73.8/82 = 9/10 or 0.9
You could do the same thing with the other two numbers too (92/82.8), gives the same answer.
Times the ratio by the distance of the bigger triangle:
0.9 x 47 = 42.3m
<span>. How
would we place the decimal point when we multiply 3.7 x 5.1
Notice that the decimal point is place between the tenths place and ones place
of the digit.
And we have only ones and tenths value in the given numbers: Let’s start
multiplying both given to determine where will be the decimal point be placed:
=> 3.7 x 5.1 = 18.87
Notice the value of our product.
WE now have 4 digits, 2 in the whole number place and 2 in the decimal place.</span>
