If a line crosses the y-axis at (0,-3) and has a slope of 3, what is the equation of the line?

Okay so first you need to put it into point slope form which is y - y1=m(x-x1)

So y + 3 = 3 ( x - 0)
y+3 = 3x - 0

then carry the 3 over.

y= 3x - 0 - 3

y= 3x -3 is your answer.

Y=mx+b
m=slope
b=y intercept (take the point and take the y value and input it for b)

crosses y axis=y intercept=(0,-3), b=-3
slope=3
y=3x-3

Answer:

15.40/3.5=$4.40 dollars a pound

7.65/1.8=$4.25 dollars a pound

Step-by-step explanation:

divide to get the unit price

so 7.65/1.8=$4.25 dollars a pound is the cheaper unit as well.

Find the amount in a continuously compiunded account for the following condition. Principal, $4000; Annual interest rate, 5.1%;

Ket [755]

A = P*e^(rt)

Here,

A = $4000*e^(0.051*2) = $4000*e^1.02 = $4000(2.773) = $11092.78

Note: This seems very high to me.

To the nearest degree what is the measure of each exterior angle of a regular dodecagon

malfutka [58]

Answer:

$30^{\circ}$

Step-by-step explanation:

We are asked to find the measure of each exterior angle of a regular dodecagon.

We know that a regular dodecagon is a 12 sided regular polygon with each side equal.

We know that measure of each angle of n-sided regular polygon can be found using formula:

$\text{Each exterior angle}=\frac{360^{\circ}}{n}$

Upon substituting $n=12$ in above formula, we will get:

$\text{Each exterior angle of a regular dodecagon}=\frac{360^{\circ}}{12}$

$\text{Each exterior angle of a regular dodecagon}=30^{\circ}$

Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.

The sides of this rectangle are

Naddik [55]

The longer side is at first 7cm and the shorter is 2cm.

So since 7cm(the longer side)×5=35cm then the shorter side(2cm) multiplied by 5 should give you the right answer.
