Answer:
ueidicjfkfktitorr*rtt
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:
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.

Does (-3, 3) make the equation y = -3x true?
========================================================
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
Solve the inequality and graph the solution.

Why would your savings account “lose value” if the rate of return you receive is lower than the rate of inflation?
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

3.67 x 10 the the 9 power
Answer:
3670000000
Step-by-step explanation:
what’s 0.17 repeating as a fraction
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

Write an equation of the line passing through the point (-3, -3) that is perpendicular to the line y=-7/23x+9
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:
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°

Write the expression as a monomial in its standard form.
(–0.2b^6)^3*5b
It's kind of confusing when I write it like that without the exponents and stuff but yeah please help thanks
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.

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
