Explain 3 areas in everyday life where you use math.

Answer:

[tex] {y}^{8} + 8 {y}^{7} + 28 {y}^{6} + 56 {y}^{5} + 70 {y}^{4} + 56 {y}^{3} + 28 {y}^{2} + 8y + 1[/tex]

Answer:

Step-by-step explanation:

This is an ugly binomial expansion, which you should try to remember

These are the coefficients for the power

1,2,1 for power two

1,3,3,1 for p=3

1,4,6,4,1 for p=4

1,5,10,10,5,1 for p=5

you should see a pattern here :)

1,8,28,56,70,56,28,8,1

In general the terms are ordered for the expansion of (a+b) that has the form

a^n(b^0)+a^(n-1)b^1+...a^0(b^n) since we have (y+1)^8 we wind up with

y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

Answer:

81m

Step-by-step explanation:

1/9 = 9/x

x = 81

Answer: B

Step-by-step explanation:

Answer:

answer is 17

Step-by-step explanation:

by (a+b)(a-b) = a²-b² identity

(√20-√3) (√20+√3)

= √20²-√3²

=20-3

=17

Answer:

No, because as the x-values are increasing by a constant amount, the y-values are not being multiplied by a constant amount.

Step-by-step explanation:

We have a set of ordered pairs of the form (x, y)

If a function is exponential then the ratio between the consecutive values of y, is always equal to a constant.

This means that:

\frac{y_2}{y_1}=\frac{y_3}{y_2}=\frac{y_4}{y_3}=by1y2=y2y3=y3y4=b

This is: y_2=by_1y2=by1

Now we have this set of points {(-1, -5), (0, -3), (1, -1), (2, 1)}

Observe that:

\begin{gathered}\frac{y_2}{y_1}=\frac{-3}{-5}=\frac{3}{5}\\\\\frac{y_3}{y_2}=\frac{-1}{-3}=\frac{1}{3}\\\\\frac{3}{5}\neq \frac{1}{3}\end{gathered}y1y2=−5−3=53y2y3=−3−1=3153=31

Then the values of y are not multiplied by a constant amount "b"

Answer

Step-by-ste$6.48- $6.00= $.48

.48÷ 6.0= 0.08

0.08 = 8%

tax rate is 8%

p explanation:

Answer:

3%

Step-by-step explanation:

6.18-6.00 = .18

.18/6.00= .03

.03= 3%

Answer:

t = 30

Step-by-step explanation:

[tex]\frac{6}{1} = \frac{t}{5}[/tex]

you can tell you need to multiple by 5 from the denominators. 1 *5 = 5. Then, just multiply 6 by 5 and get 30.

Answer:

The answer would be 45

Step-by-step explanation:

120-60=60 which is how much he gets back from selling a bike. divide 2700/60=45 bicycles that have to be sold.

Answer:

thx for the 32 points

Step-by-step explanation:

Answer:

8.31

Step-by-step explanation:

By Pythagoras Theorem,

(10)² + x² = (13)²

=> x² = (13)² - (10)²

=> x² = 169 - 100

=> x² = 69

=> x = [tex]\sqrt{69}[/tex]

=> x ≈ 8.31

Answer:

6 x 1.5 = 9 => 0.25 yards

Step-by-step explanation:

6 in a line, means times 6. Times do unit converison to get 0.25 yd.

Answer:

110

Step-by-step explanation:

a probabability of rolling a 2 on a dice is 1/6, and times that by 660 is 660/6 which equals 110

hope this helps!

please give brainliest. Thanks!

Answer:

110 times

Step-by-step explanation:

The probability (P) of rolling a 2 is

P(2) = [tex]\frac{1}{6}[/tex]

expected number = [tex]\frac{1}{6}[/tex] × 660 = 110

Step-by-step explanation:

hello lol

these are alternate exterior angles so they are equal

26x + 1 = 131

26x  = 130

x = 5

Answer:

 {x,y} = {3/7,-43/7}

Step-by-step explanation:

System of Linear Equations entered :

  [1]    x + 3y = -18

  [2]    -x + 4y = -25

Graphic Representation of the Equations :

   3y + x = -18        4y - x = -25  

Solve by Substitution :

// Solve equation [1] for the variable  x  

 [1]    x = -3y - 18

// Plug this in for variable  x  in equation [2]

  [2]    -(-3y-18) + 4y = -25

  [2]    7y = -43

// Solve equation [2] for the variable  y  

  [2]    7y = - 43  

  [2]    y = - 43/7  

// By now we know this much :

   x = -3y-18

   y = -43/7

// Use the  y  value to solve for  x  

   x = -3(-43/7)-18 = 3/7  

Solution :

{x,y} = {3/7,-43/7}

Answer:

$6,000

Step-by-step explanation:

We have to start by finding the conversation rate.

So, we can divide 9,600 by 8 to find how much the ratio is being multiplied by.

9,600 / 8 = 1200

Now that we know the conversion rate, we can multiply by five to find how much the expenses really cost, according to the ratio.

1200 * 5 = 6000

Their expenses this month are 6000

==================================================

Work Shown:

If line a is parallel to line b, then the alternate interior angles (4x-30) and (2x) are equal to one another.

Let's solve for x

4x-30 = 2x

4x-2x = 30

2x = 30

x = 30/2

x = 15

Answer:

y = 3x

Step-by-step explanation:

y = 3 and x = 3 doesn't touch 0, 0

Answer: 1012.50

Step-by-step explanation:

The formula for calculating Simple interest is:

= Principal × Rate × Time

= 4500 × 7 1/2% × 3

= 4500 × 7.5/100 × 3

= 4500 × 0.075 × 3

= 1012.50

Therefore, the simple interest is 1012.50
