28

Answer:

A

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is

h² = 20² + 20² = 400 + 400 = 800 ( take the square root of both sides )

h = [tex]\sqrt{800}[/tex] ≈ 28 in ( to the nearest whole number )

Answer:

whats the question

Step-by-step explanation:

what's the question??

Answer:

Inflation is the continuing reduction of the purchasing power or price level rise in a given time period.

Therefore, keeping money in a savings account that gives an interest rate that is lower than the inflation rate, in a period of high inflation will result in a reduction of the purchasing power of the amount of money plus interest in the savings account.

If the interest rate is 10%, the amount, A, in the account after a given time will be 1.1A

If the inflation rate is 15%, the value of the goods sold initially at A, will become 1.15A after the given period and the amount in the account will no longer be able to purchase the goods it was initially able to purchase, or the amount in the savings account will lose value

Step-by-step explanation:

In this exercise, we have to know some finances concepts in order to explain the problematized situation in this way we can say that:

Inflation exist the ongoing decline of the ability to purchase or price level rise fashionable a likely time period.

Explaining this concept of finance in a deeper way, we find that:

Inflation exist the ongoing decline of the purchasing power or price level rise fashionable a likely an age.

Therefore, consistency services in a account for saved money that gives an sum charged for use of money that is to say inferior the swelling rate, in a period of extreme swelling will influence a decline of the ability to purchase of the amount of services plus interest in the account for saved money.

If the sum charged for use of money exist 10%, the amount, A, fashionable the or charges after a likely opportunity will exist 1.1A

If the swelling rate exist 15%, the value of ability sold out at first at A, will evolve into 1.15A following in position or time the given extent of time and the amount fashionable the or charges will not any more within financial means purchase the goods it exist at first able to perform well to purchase, or the amount fashionable the account for saved money will lose value

Step-by-step explanation: The reason I know this is because I plugged into a graphing calculator and took the unit test.

At value D.2pi  the graph of y=4 cot^-1(2x) intersect the y-axis.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Here, given that,

y=4 cot^-1(2x)

we have to find the value at it  intersect the y-axis.

y-axis means x=0.

x=36

Step-by-step explanation:

the triangle is a right angle triangle divided into 2 at the angle representing 90°. Since the second triangle has two equal sides the angles therefore are also equal, hence

180°-72°=108°

then 108°÷2=54°. ( we divided because the angles are equal.

x=180°-90°-54°

x=36°

Answer:

y = 23x/7 +48/7

Step-by-step explanation:

perpendicular slopes are always equal to -1

so the new slope is 23/7

slope intercept form is y = mx + b where m is the slope and b is the                 y-intercept

so plug in (-3, -3 ) to get -3 = 23(-3)/7 + b

isolate b

solve

-3 = 23*-3/7 + b

-3 = -69/7 + b

add 69/7 to both sides

69/7 - 3 = b

-3 = -21/7

69/7 - 21/7 = 48/7

b = 48/7

new equation is y = 23/7 + 48/7

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Finding the slope:

Use this...

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Plug in what you know...

[tex]y_{2} =-5\\y_{1}=7\\x_{2} =0\\x_{1}=2[/tex]

Now solve...

[tex]\frac{-5-7}{0-2}=\frac{-12}{-2} =6[/tex]

So the slope is 6.

Finding the y-intercept:

Use this...

[tex]y=mx+b[/tex]

Plug in what you know...

(2,7)    (I'll be using this pair but you can choose the other one)

[tex]y = 7\\x = 2\\m = 6[/tex]

Now solve...

[tex]7=6(2)+b\\7=12+b\\b=-5[/tex]

Writing the equation:

Use this...

[tex]y=mx+b[/tex]

Plug in what you know...

[tex]m=6\\b=-5[/tex]

Now write it out...

[tex]y=6x-5[/tex]

That's it

Explanation:

The point (-3,3) means x = -3 and y = 3 pair up together

So plugging in x = -3 should lead to y = 3 if (-3,3) was a solution

Plug x = -3 into y = -3x to find that

y = -3x

y = -3*(-3)

y = 9

So x = -3 and y = 9 should be the actual pair (not x = -3 and y = 3)

---------------

Put another way

y = -3x

3 = -3(-3) ... replace x with -3 and y with 3

3 = 9 ... which is false

This shows (x,y) = (-3,3) is not a solution

Answer:

[tex]-0.04b^{19}[/tex]

Step-by-step explanation:

We have the expression [tex](-0.2b^6)^3\times 5b[/tex] and we want to rewrite/simplify this to a monomial (only one term).

First, let's expand. We can use the power of a product exponent property, where [tex](ab)^x=a^xb^x[/tex]

We have:

[tex](-0.2b^6)^3\times 5b[/tex]

Using the above property, this will be:

[tex]=(-0.2)^3(b^6)^3\times5b[/tex]

(-0.2) cubed is -0.008. So, this becomes:

[tex]=-0.008(b^6)^3\times 5b[/tex]

We can now use the power of a power property, where [tex](x^a)^b=x^{ab}[/tex].

Therefore, this will give us:

[tex]=-0.008b^{6\times 3}\times 5b[/tex]

Evaluate:

[tex]=-0.008b^{18}\times 5b[/tex]

Notice that 5b is the same as 5 times b to the first power. So:

[tex]=-0.008\times b^{18}\times5\times b^1[/tex]

We can rearrange this to get:

[tex]=-0.008\times 5\times b^{18}\times b^1[/tex]

When we multiply exponents with the same base, we will simply add the exponents. -0.008 times 5 is -0.04. Therefore, this yields:

[tex]=-0.04b^{18+1}\\=-0.04b^{19}[/tex]

Therefore, our final answer is [tex]-0.04b^{19}[/tex].

And this is indeed a monomial since this only has one term.

s = 70

The maximum score will be 74 and the minimum score will be 70.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Leona was in a golf tournament last week. All of her rounds of gold were within 2 strokes of par and par was 72.

The value of the maximum and minimum scores will be calculated as below:-

Maximum score:-

l s - 72 l = 2

s - 72 = 2

s = 74

Minimum score:-

s - 72 = -2

s = 70

Therefore, the maximum score will be 74 and the minimum score will be 70.

Answer:

  2) V = 2000·1.07^t; $6317.63 after 17 years

  3) D = 950·0.82^t; 2 months to a balance of $650

Step-by-step explanation:

Exponential equations are not so difficult. They are generally of the form ...

  f(t) = (initial value) × (growth factor)^t

where t is the number of time periods to which growth factor applies. (I problem 2, that is years; in problem 3, that is months.)

The growth factor can be written different ways. In terms of growth rate, it is ...

  growth factor = 1 + growth rate

Often, the growth rate is expressed as a percentage. It may be positive or negative.

__

2) The initial value is $2000, and the growth rate is 7% = 0.07. So, the exponential equation for value is ...

  V = 2000·1.07^t

The value after 17 years is ...

  V = 2000·1.07^17 = 6317.63

__

3) The initial value is $950, and the growth rate is -18% = -0.18. That means the growth factor is 1-0.18 = 0.82. So, the exponential equation for the remaining debt is ...

  D = 950·0.82^t . . . . . where t is in months

We want to find the value of t when D=650, so we put that in the equation and solve for t. Logarithms are required.

  650 = 950·0.82^t

  650/950 = 0.82^t . . . . . . . . . . divide by 950

  log(650/950) = t·log(0.82) . . . take logarithms

  log(650/950)/log(0.82) = t ≈ 1.91

It will take about 2 months for the balance to be about $650.

Answer:

54 bales

Step-by-step explanation:

Answer:

54 Bales

Step-by-step explanation:

Subtract 22 from 76 to get 54

If it's just the 7 that's repeating, let

x = 0.1777...

Then

10x = 1.777...

100x = 17.777...

100x - 10x = 17.777... - 1.777...

90x = 16

x = 16/90 = 8/45

If both 1 and 7 are repeating, let

x = 0.171717...

Then

100x = 17.171717...

100x - x = 17.171717... - 0.171717...

99x = 17

x = 17/99
