Answer:

\boxed {\boxed {\sf (0,1)}}

Step-by-step explanation:

First, let's define the points.

The first point is right 4 and up 7. The second point is left -4 and down 5. Therefore, the points are (4 , 7) and (-4 , -5).

Next, use the midpoint formula to find the midpoint.

(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )

Since, the points are (4,7) and (-4,-5):

x_1=4\\y_1=7 \\x_2= -4 \\y_2= -5

Substitute the points into the formula.

(\frac{4+-4}{2}, \frac{-5+7}{2}  )

Solve the numerators first.

(\frac{0}{2} , \frac {2}{2})

Divide.

(0,1)

The midpoint of the two points is <u>(0,1)</u>

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-4, -5)

Point (4, 7)

<u>Step 2: Find Midpoint</u>

Simply plug in your coordinates into the midpoint formula to find midpoint

  1. Substitute [MF]:                       (\frac{-4+4}{2},\frac{-5+7}{2})
  2. Add:                                         (\frac{0}{2},\frac{2}{2})
  3. Divide:                                     (0,1)

A small combination lock on a suitcase has 55 ​wheels, each labeled with the 10 digits 0 to 9. How many 55 digit combinations ar
den301095 [7]
Suppose a_n is the number of possible combinations for a suitcase with a lock consisting of n wheels. If you added one more wheel onto the lock, there would only be 9 allowed possible digits you can use for the new wheel. This means the number of possible combinations for n+1 wheels, or a_{n+1} is given recursively by the formula

a_{n+1}=9a_n

starting with a_1=10 (because you can start the combination with any one of the ten available digits 0 through 9).

For example, if the combination for a 3-wheel lock is 282, then a 4-wheel lock can be any one of 2820, 2821, 2823, ..., 2829 (nine possibilities depending on the second-to-last digit).

By substitution, you have

a_{n+1}=9a_n=9^2a_{n-1}=9^3a_{n-2}=\cdots=9^na_1=10\times9^n

This means a lock with 55 wheels will have

a_{55}=10\times9^{54}

possible combinations (a number with 53 digits).

A small square pyramid of height 6 cm was removed from the top of a large square pyramid of height 12cm forming the solid shown.
Semmy [17]

Answer:

15,872 mm³

Step-by-step explanation:

given:

A small square pyramid of height 6 cm was removed from the top of a large square pyramid of height 12cm forming the solid shown.

Find:

the exact volume of the solid

solution:

volume of square base pyramid = (base area)² * h/3

where total h = 12 cm

height of top pyramid (ht)= 6 cm

height of bottom pyramid (hb) = 6 cm

bottom volume =  total volume - the volume on top

so,

total volume = 1/3 (base area)² h

                     = 1/3 (8*8)² * 12

                     = 16,384 mm³

volume on top = 1/3 (top base area)² h

                         = 1/3 (4*4)² * 6

                         = 512 mm³

finally: get the bottom volume:

bottom volume =  total volume - the volume on top

bot. vol = 16,384 mm³ - 512 mm³

             = 15,872 mm³

therefore,

the volume of the cut  pyramid base = 15,872 mm³
