The decimal number 0.75 means:

1 answer:

8 0

The decimal number 0.75 means:

In expanded form it would be written as: (7x/10) + (5x1/100)

In written form it would be written as: 75 hundredths.
Hint: If you were writing this number in written form, always remember that if the number is after the deciml point it has to end with "th" like hundredths ends with "th". If the number is before the decimal point it doesn't end with a "th".

I hope this helped. I'm always glad to help. Please make sure to give me a Brainliest for answering your question. (Not saying you need to. It's just that I need two more Brainliest to get to the next level).

You're Welcome! :D

Write the equation of the line that passes through the points (-9, -8) and (–6,6).

sveta [45]

Answer:

Slope - intercept form $y = \frac{14}{3} x + 34$

Step-by-step explanation:

Explanation:-

Given points are ( -9 ,-8 ) and (-6,6)

slope of given two points

$m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{6-(-8)}{-6-(-9)} = \frac{14}{3}$

The equation of the straight line passing through the points and having slope

$y - y_{1} = m ( x - x_{1} )$

$y - (-8) = \frac{14}{3} ( x - (-9) )$

3 y + 2 4 = 14 x + 126

3 y = 14 x + 126 - 24

3 y = 14 x + 102

$y = \frac{14}{3} + \frac{102}{3}$

$y = \frac{14}{3} x + 34$

Slope - intercept form y= mx +C

Slope - intercept form $y = \frac{14}{3} x + 34$

How do i make a table of values for each function rule and then graph the function for these examples:

Sholpan [36]

$\bf \begin{array}{ccllll}
y=1.5x-3\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\

x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
-3&1.5(-3)-3\\
-2&1.5(-2)-3\\
-1&1.5(-1)-3\\
0&1.5(0)-3\\
1&1.5(1)-3\\
...&...
\end{array}$ $\bf \begin{array}{ccllll}
y=-x^2+4\\
\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\textendash\\

x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
-3&-(-3)^2+4\\
-2&-(-2)^2+4\\
-1&-(-1)^2+4\\
0&-(0)^2+4\\
1&-(1)^2+4\\
...&...
\end{array}$

and so on, and then, you graph those x,y coordinates

How many years will it take for the account to reach $18,600? Round your answer to the nearest hundredth

Margarita [4]

it depends how the interest is calculated, but there's not much of a difference

assuming its continuously compouned, you use this formula: A(t)=Pe^(rt), where A is the final amount, P is the initial investment, r is the interest, and t is the time in years

you want to find t such that A(t)=18,600 so 18,600=1000e^(.0675t)

you need to use logarithm to figure it out, take the natural log of both sides

the following properties will come into use:

ln(a*b)=ln(a)+ln(b)
ln(a^b)=bln(a)
ln(e)=1

taking the natural log

ln(18,600)=ln(1000e^(.0675t))

ln(18,600)=ln(1000)+ln(e^.0675t)

ln(18600)=ln(1000) + .0675t

now solve for t: t= (ln(18600)-ln(1000))/.0675

t=43.31
