Answer:
Solution,
CP of a bicycle=$3000
Marked up=40%
Now,
→40% of $3000
→40/100x$3000
→$1200
→$3000+$1200=$4200
Again,
Discount(d)=30%
→30%of $4200
→30/100x$4200
→$1260
Hence, the discount price of the bicycle is $1260
Step-by-step explanation:
The amount invested by Mr.Smith in 5% is $240 .
<u>Step-by-step explanation:</u>
We have , Mr. Smith invests a certain amount of money at 8% and twice as much at 5%. If his annual income from the two investments is $720 . Let us suppose that Mr.Smith invest $x so :
Amount of money invested in 5% is . And, amount of money invested in 8% is twice that of 5% i.e. .
Now, total investment is $720 so,
+( ) = $720
⇒

⇒
⇒
The amount invested by Mr.Smith in 5% is i.e.. ∴ The amount invested by Mr.Smith in 5% is $240 .
3/4 is equal to 75%, or if you were going by .25=1/4 than it would be .75
Answer:
y=3x−4
Step-by-step explanation:
find the tangent line to f(x)=x2−3x+5 at x=3
First, find the value of the function at the given point: y0=f(3)=5
Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point: m=f′(3)
Find the derivative: f′(x)=2x−3
Next, we evaluate the derivative at the given point to find the slope.
m=f′(3)=3
Finally, the equation of the tangent line is y−y0=m(x−x0)
Plug the values that we found, we get that y−(5)=3(x−(3))
So basically: y=3x−4
