Hi,

I think this is the table, correct?

Number of Tubes        3                5                      7

Cost ($)                    12              20                     28

we can calculate the prize as the number of tubes multiplied by 4:
3*4=12
5*4=20
7*4=28

which means that one tube costs 4 dollars!

However, in the store A two tubes cost 7, which means that one costs half of this -3.5

So Store B is more expensive (4 dollars per 4 rather than 3.5 as in Store A).

In each triangle p is the circumcenter use circumcenter theorem to solve for the givin values
timurjin [86]

Answer:

Circumcenter theorem states that the vertices of the each triangle are equidistant from the circumcenter.

As per the statement:

It is given that: P is the circumference

From the given figure:

CP = 12 units.

then;

by circumcenter theorem;

AP= BP =CP = 12 units.

Next find the value of AB:

Labelled the diagram:

AD = 11 units

then;

AB = AD+DB

Since: AD=DB [You can see it from the given figure]

then;

AB = 2AD = 2(11) = 22 units

Therefore, the value of BP and AB are: 12 units and 22 units

How many distinguishable ways can the letters of the word millimicron be arranged in order?
soldi70 [24.7K]

total no. of letters = 11

millimicron

dissecting will give us:

 

no. of m = 2, no. of i = 3, no. of l = 2, no. of c = 1, no. of n =1, no. of r = 1, no. of o = 1

 

 we are going to compute this by using permutation

total no. of ways to arrangement = 11!/ [ 2!* 3! * 2! * 1! *1! *1! *1!]

= 39,916,800/ 24

= 1,663,200 is the answer

Use quadratic regression to find
Rashid [163]

The quadratic equation is given by:

y = 3x² + 10x - 8

The standard equation of a parabola is given by:

y = ax² + bx + c

Where a, b, c are constants

At point (4, 80):

80 = a(4)² + b(4) + c

16a + 4b + c = 80     (1)

At point (-3, -11):

-11 = a(-3)² + b(-3) + c

9a - 3b + c = -11     (2)

At point (-1, -15):

-15 = a(-1)² + b(-1) + c

a - b + c = -15     (3)

Solving equations 1, 2 and 3 simultaneously gives:

a = 3, b = 10, c = -8

Therefore the quadratic equation becomes:

y = 3x² + 10x - 8
