Can you draw different functions that have the same x-intercepts and the same domain and range?
iogann1982 [59]
I'm pretty sure the answer is no.  A function looks like this: f(x) = mx + c.  Let's add another function, f(y) = ny + d.  If the x-intercept is the same, we can subtract c and d from their respective equations. f(x) = mx, f(y) = ny. If the domains are the same, then x and y can have the same value, so we divide it out. f(x) = m, f(y) = n.  Finally, if the ranges are the same, the value of f(x) = f(y).  So by the substitution property, m=n.  Since all the variables equal each other, both functions are equal to f(x) = mx+c!  Therefore, they can only be the same function.

Find the perimeter and area (last question I need on my test
Lera25 [3.4K]

Step-by-step explanation:

Let AB be 5cm

AC be 13cm

According to Pyathagros therom

AC²=AB²+BC²

13²=5²+BC²

169=25+BC²

BC²=169-25

BC²=144

BC=√144

BC=12cm

Area of ∆ABC=½×base×hight

=½×12×5

=½×60

=30cm²

Parimeter of ∆ABC=a+b+c

=5+12+13

=30cm

A coin is tossed 4 times. Find the probability of getting at 4 tails in a row.
7nadin3 [17]

Answer:

6.25%

Step-by-step explanation:

Each time you flip a coin, there is a 50% probability of it landing on tails. Each time you flip the coin, the 50% gets multiplied by \frac{1}{2}.

\frac{1}{2} to the power of <em>4 </em>is 0.0625. 0.0625 in percentage form is of course 6.25%

Rahul sold a painting at 10% profit. If he had sold it for 240 more, he would have made 15% profit. What is the C.P. of the pain
dangina [55]

Answer:

$4800

Step-by-step explanation:

Let x be the C.P of the painting.

Profit=10% of x

Profit=\frac{10}{100}\times x=\frac{10x}{100}

If S.P increase by 240 then

Profit=15% of x=\frac{15x}{100}

For first case

S.P=C.P+ Profit

S.P=x+10x/100

S.P=\frac{100x+10x}{100}=\frac{110}{100}x

For second case

New S.P=x+\frac{15}{100}x

         =\frac{115}{100}x

According to question

240+S.P=\frac{115}{100}x

240+\frac{110x}{100}=\frac{115}{100}x

240=\frac{115}{100}x-\frac{110x}{100}

240=\frac{115x-110x}{100}

240=\frac{5}{100}x

x=\frac{240\times 100}{5}

x=4800

Hence, the C.P of the painting=$4800
