Answer:

[tex]\frac{9}{4}[/tex] - (x - [tex]\frac{3}{2}[/tex] )²

Step-by-step explanation:

Given

3x - x² ← factor out - 1 from each term

= - (x² - 3x)

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² - 3x

= - (x² + 2(- [tex]\frac{3}{2}[/tex])x + [tex]\frac{9}{4}[/tex] - [tex]\frac{9}{4}[/tex] )

= - (x - [tex]\frac{3}{2}[/tex] )² - 1(- [tex]\frac{9}{4}[/tex] )

= [tex]\frac{9}{4}[/tex] - (x - [tex]\frac{3}{2}[/tex] )²

Answer:

  N = 250

Step-by-step explanation:

The way your question is written, the answer is a number of 2582 digits, much too large to show here. We assume you actually want N such that 10^N is the largest power of 10 that will divide 1005!.

__

That factor is limited by the number of factors of 2 and 5 in 1005!. Of those, there are far more factors of 2, so the actual limit is the number of factors of 5 in 1005!.

Every 5th number is divisible by 5, so there are 1005/5 = 201 numbers divisible by 5 in 1005!.

Every 5th one of those is divisible by another factor of 5, so an additional 201/5 ≈ 40.

Every 5th one of those is divisible by another factor of 5, so an additional 40/5 = 8.

Finally, every 5th one of those has yet another factor of 5, so an additional 8/5 ≈ 1.

Then the total number of factors of 5 in 1005! is 201 +40 +8 + 1 = 250.

That is, the number 1005! will end in 250 zeros. It will be divisible by 10^250.

  N = 250

Explanation:

For the confidence interval (a,b), the midpoint is c = (a+b)/2

This midpoint is the sample proportion. This is because the confidence interval is built around this center point.

The midpoint of the interval (0.52, 0.58) is (0.52+0.58)/2 = 0.55

Answer:

angle y=59 degrees

angle a= 62 degrees

Step-by-step explanation:

angle t =59

angle t=angle y(given)

therefore;

  angle y=59 degrees

angle a +angle t +angle y=180(sum of the interior angles of a triangle)

 a          +59        +59        =180

               a+118                  =180

                                     a   =180-118

                                       a =  62 degrees

Step-by-step explanation:

[tex]5 - \frac{3}{4} [/tex]

[tex] \frac{5}{1} - \frac{3}{4} = \frac{5 \times 4}{1 \times 4} = \frac{3}{4} [/tex]

Answer:

17/4-4 1/4 or 4.25

Step-by-step explanation:

Answer:

100 times larger.

Step-by-step explanation:

The 7 in the thousands place can be written as 7000

The 7 in the tens place can be written as 70

Times greater = 7000 / 70 = 100

So the answer is 100 times larger for the 7 in the thousands place to the 7 in the 10s place.

Answer:

Example:

0 - 6 = -6

4 - 10 = -6

Answer:

  a) they are congruent

  b) isosceles; ∠IBC≅∠ICB

Step-by-step explanation:

a) We are given that ΔABC is isosceles, such that AB≅AC. Points D and E are located so that AD≅AE. Of course, ∠A≅∠A, so ΔACE ≅ ΔABD by SAS. Then angles ABD and ACE are congruent by CPCTC.

__

b) Angle IBC is the difference between angle ABC and angle ABD. Angle ICB is the difference between angle ACB and angle ACE. These differences are between values that are the same, so the differences are the same. That means ∠IBC≅∠ICB, and ΔIBC is isosceles.

Answer:

9

Step-by-step explanation:

Answer: 164 students passed and 41 students failed.

Step-by-step explanation:

Let the number of students be x

x students failed, but 4 times the failed students passed.

So 4x students passed and x students failed.

4x + x = 205

5x = 205

x = 205/5

x = 41

41 times 4 is 164 and 41 times 1 is 41.

So 164 students passed and 41 students failed

Answer:

Your answer is option a.

Answer:

a. 9(8+7)

Step-by-step explanation:

If you distribute the 9 into the equation, You're basically multiplying the 9 by each term so it really becomes:

(9*8) + (9*7)

Which leaves you with:

72 + 63

Answer:

X=25

Step-by-step explanation:

This is because X has to be greater than 23. Because you are taking away 35 and the answer is 2, you have to add 23 and 2, and that gives you 25!

Answer:

B: $0.60

Step-by-step explanation:

4x+6=8.40

4x=2.40

2.40 / 4 = .6

.6 = 0.60 or 60 cents

Answer:$0.60

Step-by-step explanation:

A bag a kibble is 6$

Subtract the cost for the kibble to the cost of all products.

  $8.40

-  $6.00  

  $2.40...  is the cost for all 4 cans of cat food.

Then divide $2.40 by 4... That will be B) $0.60

E.13x-7

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

[tex]a = \pi r {}^{2} [/tex]

The area of a circle given it diameter is

[tex]a = \pi( \frac{d}{2} ) {}^{2} [/tex]

So let answers question 1-4.

1. The area is

[tex]1024\pi[/tex]

2. The area is

[tex]576\pi[/tex]

3.

[tex]1.225\pi[/tex]

4.

[tex]309.76\pi[/tex]

For the 5th problem, circumference is

[tex]\pi \times d[/tex]

where d is the diameter and

[tex]2\pi r[/tex]

where r is the radius.

A circumference of 100 m means the radius is 50 because

[tex]2\pi \times r = 100\pi[/tex]

[tex]r = 50[/tex]

So this means the area is

[tex]2500 {\pi}[/tex]
