What is the equation of a line perpendicular to y=1/4x+2 that passes through the point (0,1)
ipn [44]

Answer: y = -4x + 1 or y = 1 - 4x

Step-by-step explanation:

First, we have to find the slope of the perpendicular. The slope of the line perpendicular to the other is the <u>reciprocal and opposite value</u> of the other line's slope.

This means that the slope perpendicular to y = 1/4x + 2 is -4, or -4/1.

Now we need to find the y-intercept, to do that we will use the equation y = mx + b. m = slope, b = y-intercept.

Plug in the values.

1 = -4(0) + b

Simplify.

1 = 0 + b

1 = b

Our y-intercept is 1.

Now we can form the slope-intercept equation for the line perpendicular to y = 1/4x + 2 that passes through the point (0, 1).

y = -4x + 1

In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor sho
RoseWind [281]

Answer:

325,452 more meteors fell during the Perseid meteor shower

Step-by-step explanation:

An year has 365 days.

Each day has 24 hours.

Each hour has 60 minutes.

Minutes in an year:

365*24*60 = 525600

Persoid:

1 + \frac{1}{5} = 1 + 0.2 = 1.2

One each 1.2 minutes. How many during an year?

1 meteor - 1.2 minutes.

x meteors - 525600 minutes.

1.2x = 525600

x = \frac{525600}{1.2}

x = 438000

438,000 meteors fell during the Persoid shower.

Leonid:

4 + \frac{2}{3} = 4.67

One each 4.67 minutes. How many during an year.

1 meteor - 4.67 minutes.

x meteors - 525600 minutes.

4.67x = 525600

x = \frac{525600}{4.67}

x = 112548

112,548 meteors fell during the Leonid Shower.

How many more meteors fell during the Perseid meteor shower?

438,000 - 112,548 = 325,452

325,452 more meteors fell during the Perseid meteor shower

What does | 3+i | equal
prohojiy [21]
The straight lines are asking to find the modulus or the size of the complex number.
For a complex number  z = x + iy,  [z] = √(x^2 +y^2)
Where x = Real Number, y = Imaginary number.
For 3 +i,  x = 3, y = 1    (Note y is what number that is attached to i)

[3 + i] = √(3^2 +1^2) = √10 = 3.162

zubka84 [21]

Answer:

2x + 15= 33

Step-by-step explanation:

Jerry started doing sit-ups every day. The first day he did 17 sit-ups. Every day after that he did 4 more sit-ups than he had done the previous day. Today Jerry did 73 sit-ups. Write an equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day. Let n represent the number of days.
