Answer:

The 2 in the hundreths is 10% of the 2 in the tenths

Step-by-step explanation:

We are given the number 15.2201

#The value of 2 in the tenths:

0.2

#The value of 2 in the hundredths:

0.02

The difference of the 2 in the tenths and in the hundredths is:

=2_t-2_h\\\\=0.2-0.02\\\\=0.18\\\\\#2_h \ as \ a \ \% \ of \ 2_t\\=\frac{2_h}{2_t}\times 100\%\\\\=\frac{0.02}{0.2}\times100\%\\\\2_h=10\% \ of\  2_t

Hence, the difference between the 2 in the tenths  minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.

Find the slope of the line that passes through the pair of points listed below.<br> (-2, -3), (6,5)
antoniya [11.8K]

Finding the slope using two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =5\\y_{1} =-3\\x_{2} =6\\x_{1} =-2

^^^Plug these numbers into the formula for slope...

\frac{5-(-3)}{6 - (-2)}

\frac{8}{8}

1

^^^This is your slope

Hope this helped!

Maria is installing gutters on her rectangular shed that measures 10 ft by 9 ft she has 23 ft of gutter already and need to purc
Paha777 [63]

Answer:

Maria needs 3 lengths of gutter of finish the shed.

Step-by-step explanation:

We need to calculate the perimeter of the rectangular shed to know how much  5 feet gutter is needed.

The perimeter of the shed is p = 2(l + b) where l = 10ft and b = 9 ft

p = 2(10 + 9) = 2(19) = 38 ft

Now, the perimeter of the shed also equal 23 ft of gutter already installed plus 5x ft gutter where x = number of gutters.

So 23 + 5x = 38

collecting like terms, we have

5x = 38 - 23

5x = 15

dividing through by 5 we have

5x/5 = 15/5

x = 15/5

x = 3

So, Maria needs 3 lengths of gutter of finish the shed.

Which statement best describes the effect on the graph of y = (x – 9)2 if the equation is changed to y = (x + 9)2? The graph mov
alexandr402 [8]

Answer:

Third option: The graph moves left 18 units.

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If f(x)+k, the function is shifted up "k" units.

If f(x)-k, the function is shifted down "k" units.

If f(x+k), the function is shifted left "k" units.

If f(x-k), the function is shifted right "k" units.

In this case, we can observe that graph of y = (x - 9)^2 is changed to y = (x + 9)^2

Since:

 -9+18=9

We can conclude that the function y = (x - 9)^2 is shifted left 18 units to get the function y = (x + 9)^2.
