One blue whale weighed
4.2 x 105 pounds while another
weighed 2.6 x 105. Find the difference in weight and express your answer in scientific notation
2.4 x 10
1.6 x 10
1.6 x 10°
1.6 × 10⁵
To find the answer we first need to find the value of 4.2 × 10⁵ and 2.6 × 10⁵. We know that 10⁵ = 100000. Now we multiply 4.2 and 2.6 by 100000 which makes them 420000 and 260000. Now we find the difference= 420000 - 260000 = 160000. Now to put it in to scientific notation, we just divide it by 100000 so, 160000 ÷ 100000 = 1.6 × 10⁵ ( always remember to keep 10⁵ in your answer not 100000).

Choose the equation that represents the line passing through the point (2. - 5) with a slope of -3.
Y= -3x - 13
y=-3x + 11
y=-3x + 13
Y=-3x + 1
Answer:
Step-by-step explanation:
y + 5 = -3(x - 2)
y + 5 = -3x + 6
y = -3x + 1
Option 4 is the answer

Your answer is D!
Step-by-step explanation:
Y=-3x + 1
How is multiplying complex numbers different
from adding or subtracting complex numbers?
Let P and Q be two complex numbers such that
P = a+bi
Q = c+di
Where a,b,c,d are real numbers and i = sqrt(-1).
This means i^2 = -1.
-------------------
Adding P and Q means
P+Q = (a+bi)+(c+di)
P+Q = a+bi + c+di
P+Q = (a+c) + (bi+di)
P+Q = (a+c) + (b+d)i
As you can see, we just add the corresponding components together.
-------------------
Subtraction is a similar story.
P-Q = (a+bi)-(c+di)
P-Q = a+bi - c-di
P-Q = (a-c) + (bi-di)
P-Q = (a-c) + (b-d)i
We subtract the corresponding components
-------------------
Multiplication is a bit more complicated.
We'll use the FOIL rule
P*Q = (a+bi)*(c+di)
P*Q = a*c + a*di + bi*c + bi*di
P*Q = a*c + ad*i + bc*i + bd*i^2
P*Q = a*c + ad*i + bc*i + bd*(-1)
P*Q = a*c + ad*i + bc*i - bd
P*Q = (ac - bd) + (ad*i + bc*i)
P*Q = (ac - bd) + (ad + bc)i
Unfortunately multiplication isn't as simple as addition or subtraction, but we can at least make a tidy formula for it. You could also use the box method to visually organize the terms into a table to help multiply out P and Q.

A square has area of 9 yd squared. What is the length of both sides?
Answer:
Each side is 3 yds
Step-by-step explanation:
The area of a square is given by
A = s^2
9 = s^2
Take the square root of each side
sqrt(9) = sqrt(s^2)
3 = s
Each side is 3 yds

What is the slope of the line through (-3, 3) and (-1, -1)?
Answer:
[tex]m=-2[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-1-3}{-1-(-3)}[/tex]
[tex]m=\frac{-4}{-1+3}[/tex]
[tex]m=\frac{-4}{2}[/tex]
[tex]m=-2[/tex]

In how many ways can we write a number using the digits (0,2,3,5) and the number is greater than 100
This is a multiplicative principle's question. Let's think how we can solve that.
If we want numbers are greater than 1000, so we need numbers with 4 digit (for example: 1001, 2350 and so on).
Imagine that we need to complete four spaces: one thousands, hundreds, tens and ones. See below how to compelete each space:
One thousands: In this space, we can't use the number 0, because in this way, the number will have 3 digits and we want number with 4 digits (for example: 0235 is a 3 digits number). Therefore, we can use the numbers 2, 3 and 5 to complete this space. So, there are 3 possibilities.Hundreds: Now, we can use the number 0 and the number won't have 3 digits (for example: 2035 is a 4 digits number). Therefore, we can use the numbers 0, 2, 3 and 5 to complete this space. So, there are 4 possibililities.Tens: Ih this case, it happens the same thing that happen in the case of hundreds. Therefore, there are 4 possibilites.Ones: Finally, in this case it also happens the same thing that happen in the case os hundreds. So, there are 4 possibilites.For multiplicative principle, we just need multiply these numbers of possibilities to find the result of this question:
[tex]3\times4\times4\times4=192[/tex]
Therefore, we can write 192 numbers using the digits (0, 2, 3 and 5) and all these numbers are greater than 1000.

Find all solutions of 5−4 secx = −3 on the interval [0, 2π).
Answer:
[tex]\theta=\dfrac{\pi }{3}\\\\\theta=\dfrac{5\pi }{3}[/tex]
Step-by-step explanation:
[tex]\theta = x[/tex]
[tex]5-4 \sec (\theta) = -3[/tex]
[tex]-4 \sec (\theta) = -3-5[/tex]
[tex]-4 \sec (\theta) = -8[/tex]
[tex]\dfrac{-4 \sec (\theta)}{-4} =\dfrac{-8}{-4}[/tex]
[tex]\sec (\theta)=2[/tex]
Once
[tex]\sec(\theta)=\dfrac{1}{\cos(\theta)}[/tex]
[tex]\sec (\theta)=2 \implies \dfrac{1}{\cos(\theta)}=2 \implies \cos(\theta)=\dfrac{1}{2}[/tex]
The solutions for [tex]\cos(\theta)=\dfrac{1}{2}[/tex] are
[tex]\theta=\dfrac{\pi }{3}+2\pi n, n \in \mathbb{Z}\\\\\theta=\dfrac{5\pi }{3}+2\pi n, n \in \mathbb{Z}[/tex]
But once the interval for the solution was given,
For [tex][0, 2\pi)[/tex]
[tex]\theta=\dfrac{\pi }{3}\\\\\theta=\dfrac{5\pi }{3}[/tex]

Identify the domain and range of the relation. {(-9,2), (-4, 2), (3, 2), (9,2)
Answer:
Domain: - 9, - 4, 3, 9
Range: 2
Step-by-step explanation:
The domain is the first coordinate of an ordered pair. This means that the domain is going to be x. The range is the second coordinate of an ordered pair. This means that the range is going to be y. Since all of the second coordinates are 2 you only have to put 2 once. The domain of the set of ordered pairs is - 9, - 4, 3, 9.

What is the meaning of this notation, f^-1(x)?
Answer:
Notation. The inverse of the function f is denoted by f -1 (if your browser doesn't support superscripts, that is looks like f with an exponent of -1) and is pronounced "f inverse". ... The inverse of a function does not mean the reciprocal of a function.

Marcus invested $2000 in a bank account earning simple interest. The interest, I, he has after t years at an interest rate r is given by this equation.
l = 2000 rt
After 2 years, the total amount in the account was $2160. What was the annual interest rate?
Answer:
4%Step-by-step explanation:
GivenThe equation for simple interest:
I = 2000rtAnd values
Total = $2160t = 2r = ?SolutionInterest amount is
$2160 - $2000 = $160Solving for annual interest rate
160 = 2000*2r160 = 4000rr = 160/4000r = 0.04 0.04*100% = 4%Annual interest rate is 4%
Given that ,
I = 2000rtannual interest rate after 2yrs .
total = $ 2160t = 2yrs R = ?Now,
interest amount is
$2160-$2000 = $160Now,
annual interest rate is ;
160 = 2000 × 2r 160 = 4000r r = 160/4000 r = 0.04 r = 0.04×100% = 4% the annual rate of interest is 4%
