Equation that represents the line that passes through the point (-2,-1) and has a slope of 5

1 answer:

5 0

Straight line:
y = mx + c
m is the slope of the graph and c is the y-intercept
In this case, m = 5 as stated in the question, so...
y = 5x + c
By substituting the given co-ordinates (-2,-1) into this equation, we can find c
-1 = 5(-2) + c
-1 = -10 + c
-1 + 10 = -10 + c + 10 (Add 10 to both sides)
9 = c
c = 9
Put c = 9 into the equation:
y = 5x + 9

At the car show Inez saw a truck wheel shaped like a circle with a radius of 3 ft. She wants to know the area of the truck wheel

Nadusha1986 [10]

Answer:

$28.27ft^2$

Step-by-step explanation:

To solve this problem, we can use the area of a circle formula:

$A=\pi r^2$

<em>r = radius</em>

Lets plug the values into the equation:

$A=\pi (3^2)$ Calculate $3^2$

$A=\pi (9)$ Multiply $\pi$ and 9 together

$A=28.27$

The area of the truck wheel is $28.27ft^2$

How did he get this 1/2i ? I dont remember studying this definition in calc 1 neither calc 2!

Hitman42 [59]

The $i$ in the denominator is missing in the second expression. It should be

$\sin at=\dfrac{e^{iat}-e^{-iat}}{2i}$

This follows from

$e^{iat}=\cos at+i\sin at$
$e^{-iat}=\cos at-i\sin at$
$\implies e^{iat}-e^{-iat}=2i\sin at$
$\implies \sin at=\dfrac{e^{iat}-e^{-iat}}{2i}$
