I need the awnser for 10 please help

Answer:

Exponential notation is a powerful way to express repeated

multiplication of the same number. Specifically, powers of 10

express very large and very small numbers in a manner which is

convenient to read, write and compare.

• For any non-zero integer a, a–m 1

m a

=

• Laws of exponents are

(a) am × an = am+n

(b) am ÷ an = am–n

(c) (am)

n = amn

(d) am × bm = (ab)

m

(e) a° = 1, where a ≠ 0

(f)

m m

m

a a

b b

• Numbers can be expressed in expanded form by using exponents.

• Very large and very small numbers can be expressed in standard

form.

• Standard form is also called scientific notation form.

Step-by-step explanation:

Example 1 : Multiplicative inverse of 27 is

(a) 2–7 (b) 72 (c) – 27 (d) – 27

Solution : The Correct answer is (a).

Example 2 : The human body has about 100 billion cells. This number

can be written in exponential form as

(a) 10–11 (b) 1011 (c) 109 (d) 10–9

Solution : The correct answer is (b).

In examples 3 to 5, fill in the blanks to make the statements true.

Example 3 :

In examples 6 and 7, state whether the statements are true (T) or false (F):

Example 6 : Very small numbers can be expressed in standard form

using positive exponents.

Answer:

No; Because 9 is a factor of 4554. By divisibility rules sum of digits of 4554 is 18, which is a number divisible by 9. Hence 4554 is divisible by 9.

Answer:

Step-by-step explanation:

The exterior angle (shown) is equal to the two remote interior angles ( the ones marked with values in x).

5x + 2 + 5x = 11x - 11         Combine the terms on the left.

10x + 2 = 11x - 11                Add 11 to both sides

10x + 2 + 11 = 11x

10x + 13 = 11x                     Subtract 10x from both sides.

13 = x

But I solve like this and the answer is 9 I am student girl.

Answer:

The girl didn't follow PEMDAS

Step-by-step explanation:

PEMDAS is the order in which you solve mathematical equations.

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

If you add before multiplying you'll get a completely different answer.

The boy followed PEMDAS, while the girl didn't.

Answer:

We draw the circles on a coordinate system.  We know that a circle is has points that are equidistant from its centerpoint.   So the point where these circles are tangent is the midpoint between the centerpoints.

 We can use the midpoint formula.

 M = ((x1 + x2) / 2    ,      (y1 + y2) / 2)

 M = ((-2 + 6) / 2     ,    (3 + 9) / 2)

 M = (2, 6)

 These circles will have the same radii.

 If we take the distance between the midpoint and (-2,3), we will have the radius of the circle with this centerpoint.

If we take the distance between the midpoint and (6,9), we will have the radius of the circle with this centerpoint.

Answer:

C=9

Step-by-step explanation:

If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)

AB-(A+B)=C

10-(1+0)=9 or 11-(1+1)=9

therefore C=9

Answer:

Step-by-step explanation:

The formula is the same almost as the previous question you posted.

You want to find the major arc. That's almost the whole circle. If it was the whole circle,  the formula would be 2 * pi * r

But we only want a part of it. Just how big is the angle we use in the formula?

A circle has 360 degrees to go around it. We've cut out a slice of it that is 30 degrees.

The remaining part is 360 - 30 = 330

Arc length = angle / 360  * 2 * pi * r

r = 3 m

Arc length = 330 / 360 * 2 * pi * 3

Arc length = 0.9167 * 6 * 3.14

Arc length = 17.27

Answer:

1. 11

2. 20

3. 34

4. 12.6

5. 18

6. 105

Step-by-step explanation:

We are told that ---> t = 0, x = 1.5, y = 6, and z = 23

1. y + 5

= 6 + 5

= 11

2. z - 2x

= 23 - 2(1.5)

= 23 - 3

= 20

3. 2z - 2y

= 2(23) - 2(6)

= 46 - 12

= 34

4. 2.6y - 2x

= 2.6(6) - 2(1.5)

= 15.6 - 3

= 12.6

5. 4(y - x)

= 4(6 -  1.5)

= 24 - 6

= 18

6. 4(2 + z) + 5

= 4(2 + 23) + 5

= 8 + 92 + 5

= 105

14 + 28 + 42 + 56 + … 280

= 14 (1 + 2 + 3 + 4 + … + 20)

= 14 × 20 × 21 / 2

= 2940

where we use the well-known identity,

Answer:

billy has 1233 oranges

Step-by-step explanation:

557+676=1233

you add 557 and 676 to figure out how much billy has

you can check your answer by subtracting 1233-557=676

Answer:

Billy has 1233 oranges.

Step-by-step explanation:

This is a simple, they have this many more than this person has, so an example is the B has 1 book, but Alex has a book collection of 10 books. They both have more than one book, but Alex has 10 books in total, with 9 more than B does.

So, for this question, Tom has 557, and Bill had 676 more than him, so that would mean you need to add 676 and 557 together to get 1233 oranges for just Billy. So that would be our answer.

Answer:

(4sin²x +9cos²x + 12sinxcosx) +(9sin²x+ 4 cos²x -12sinxcosx)

13 (sin²x + cos²x)

13*1 =

HP

Answer:

see explanation

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1

Consider left side

(2sinx + 3cosx)² + (3sinx - 2cosx)² ← expand parenthesis using FOIL

= 4sin²x + 12sinxcosx + 9cos²x + 9sin²x - 12sinxcosx + 4cos²x

Collect like terms

= 13sin²x + 13cos²x ← factor out 13 from each term

= 13(sin²x + cos²x)

= 13 × 1

= 13

= right side , thus proven

Answer:

19) x = 48

20) y = 21

Step-by-step explanation:

19)

7x - 248 + x + 44 = 180

(because they're supplementary angles)

8x - 204 = 180

8x = 180 + 204

8x = 384

x = 48

20)

2y + 50 + 5y - 17 = 180

7y + 33 = 180

7y = 180 - 33

7y = 147

y = 21

Answer:

6 and 1/4

Step-by-step explanation:

1/6 x - 1/8 = 11/12

First, let's find the least common denominator (24) to make these fractions manageable to work with: 4/24 x - 3/24 = 22/24.

Next, add 3/24 to both sides: 4/24 x = 25/24.

We can cancel out the denominators at this point to get: 4x=25.

Divide both side by 4, and x = 25/4 = 6 and 1/4 or 6.25

Step-by-step explanation:

the slope = 5/3

through (1, -1)

the equation :

y -(-1) = 5/3 (x -1)

y+1 = 5/3 x -5/3

y = 5/3 x -5/3 -1
