Answer:
2.25
Step-by-step explanation:
The old width of 4 inches became a new width of 9 inches.
Old: 4 in.
New 9 in.
The old length of 6 inches became a new length of 13.5 inches.
Divide the new size by the corresponding old size.
9/4 = 2.25
13.5/6 = 2.25
You see in both cases, the scale factor is 2.25
The scale factor is 2.25
Answer:
The correct option is `(y −4) = -(4)/(3) (x +3) ..
Step-by-step explanation:
Look at the attached picture:
The points we have given are (-3, 4) and (3, -4)
Find the slope by applying the formula:
m = y2-y1/x2-x1
Here x1= -3
x2= 3
y1 = 4
y2 = -4
Now put the values in the formula:
m = -4 -4 /3 -(-3)
m = -8/3+3
m = -8/6
Now cancel the term by table of 2
m = -4/3
When two points are given, the equation of the line is
(y - y1) = m (x - x1)
y - 4 = -4/3 (x - (-3))
y-4 = -4/3 (x+3)
Thus the correct option is `(y −4) = -(4)/(3) (x +3) ....
Answer:
The percentage increase in Jayana's postcard collection is 15%
Step-by-step explanation:
Jayana had 20 postcards last year
With 3 more postcards this year
From the given equation Quantity = Percent x Whole
Here;
Let P = Percent/100%
Quantity = Increment in postcard = 3 postcards
Whole = The total postcards from last year = 20 postcards
Hence,
3 postcards = P x 20 postcards
P = 3/20 = 0.15
Recall P = Percent/100%
∴ Percent = P x 100% = 0.15 x 100% = 15%
The percentage increase in Jayana's postcard collection is 15%
Put it in a calculator.
16^5/4=262144
16^14/(16^1/2)^2=1125899906842624
