identify an equation in point slope form for the line perpendicular to y=3x+5 that passes through (4,-1)
Alborosie

Answer:

y-4 = (-1/3)(x+1)

Step-by-step explanation:

We need to identify the equation in point slope form.

The standard equation of point slope form is:

(y-y₁) = m (x-x₁)

where m is the slope and x₁ and y₁ are the points

We are given point(4,-1) so,

x₁=4 and y₁=-1

And a perpendicular line: y =3x+5

Which is equal to y = mx+b

where m is slope so, slope m = 3

Since the line is perpendicular, so the slope in negative inverse of actual slope that m = -1/m

i.e, m = -1/3

So, the equation in point slope form is:

y-(-1) = (-1/3)(x-4)

=> y+1 = (-1/3)(x-4)

An urn contains two blue balls (denoted B1 and B2) and three white balls (denoted W1, W2, and W3). One ball is drawn from the ur
Serhud [2]

Answer:

(a)\dfrac{2}{5}

(b)\dfrac{9}{25}

Step-by-step explanation:

An urn contains two blue balls (denoted B_1 \:and\: B_2) and three white balls (denoted W_1, W_2 \:and\: W_3).

In the selection, a ball is picked and replaced.

From the attached probability tree, the possible outcomes are:

B_1B_1,B_1B_2,B_1W_1,B_1W_2,B_1W_3\\B_2B_1,B_2B_2,B_2W_1,B_2W_2,B_2W_3\\W_1B_1,W_1B_2,W_1W_1,W_1W_2,W_1W_3\\W_2B_1,W_2B_2,W_2W_1,W_2W_2,W_2W_3\\W_3B_1,W_3B_2,W_3W_1,W_3W_2,W_3W_3

(a)If the first ball drawn is blue

Number of Outcomes =10

The probability that the first ball drawn is blue =\dfrac{10}{25}= \dfrac{2}{5}

(b)If only white balls are drawn

Number of Outcomes =9

Probability that only white balls are drawn =\dfrac{9}{25}

Arithmetic Operations with Numbers Written Using Scientific Notation <br> (7 × 10^−9)(5 × 10^5)
taurus [48]

Answer:

After multiplication number will be 3.5\times 10^{-5}

Step-by-step explanation:

We have given numbers which has to multiply using scientific notation

7\times 10^{-9}\times 5\times 10^5

We have to multiply the above number using scientific notation

We know that when two number are multiplied then there exponent power is being added

So when we multiply 7\times 10^{-9}\times 5\times 10^5 there power will be added and after multiplication number will be 35\times 10^{-4}=3.5\times 10^{-5}
