sorry if it's confusing I just need help lol​

Answer:

Step-by-step explanation:

recall that perpendicular lines have slopes that are opposite reciprocals. if u don't know what opposite reciprocals are, according to study.com they are, "The term opposite reciprocals refers to two numbers that have opposite signs and are flipped fractions of each other." for example, 1/2 and -2 are opposite reciprocals.

also recall that the formula to find the slope of a line is m=y2-y1/x2-x1

to solve this problem, we need to go through all of the options and find the slope of that line using the given point and point (0,4). After that, we need to check if that slope is equal to 1. One is the opposite reciprocal of -1, and -1 is the slope of the equation y= -x+4. if the slope is equal to 1, the line will be perpendicular to the line y= -x+4.

lets do the math now:

option a)

m=y2-y1/x2-x1

m=12-4/6-0

m=8/6

m=4/3

this line isnt perpendicular to y= -x +4 cuz the slope is 4/3, which isnt equal to 1

option b)

m=y2-y1/x2-x1

m=0-4/6-0

m=-4/6

m= -2/3

this line isnt perpendicular to y= -x +4 cuz the slope is -2/3, which isnt equal to 1

--------------

ok girl i dont wanna do all the rest of the calculations. just keep doing the same thing with all the other options until you find something that has a slope of 1.

toodles! :)

Answer:

6x10^-5

Step-by-step explanation:

6 Moves 5 places to the left to become the whole number.

It's negative 5 as you moved the digit from a decimal to whole number.

As it moved 5 places it's x100000.

So it's 10^5 but it's negative

Answer:

[tex]\displaystyle f^{-1}(6) = -5[/tex]

Step-by-step Explanation:

Recall that by the definition of inverse functions:

[tex]\displaystyle \text{If } f(a) = b\text{, then } f^{-1}(b) = a[/tex]

We are given the function f which contains the point (-5,6). In other words:

[tex]\displaystyle f(-5) = 6[/tex]

Then by the definition of inverse functions:

[tex]\displaystyle f^{-1}(6) = -5[/tex]

Answer: 480

Step-by-step explanation:

To solve this, you need to set up a proportion: 200/2.5 x/6

The 200 represents the km, and the 2.5 and 6 represent the hours. You can either solve this by multiplying 200 by 6 and setting it equal to 2.5 by x then solving for x, or you can find the rate the car travels in km in one hour. To do that, you divide 200 by 2.5 and get 80: this is your km per hour. Then you multiply that to 6 to see how far the car will go in 6 miles if it continues at the speed of 80 km per hour.

Answer:

Answer: 480 km

Step-by-step explanation:

As we know that if we keep speed or velocity constant, distance is directly proportional to time.

• In the first case:

[tex]{ \rm{d_{1} = kt _{1}}}[/tex]

• Substitute the variables with their respective values to find the value of constant, k

[tex]{ \rm{200 = (k \times 2.5)}} \\ \\ { \rm{k = \frac{200}{2.5} }} \\ \\ { \underline{ \rm{ \: \: k = 80 \: km {h}^{ - 1} \: \: }}}[/tex]

• In the second case

[tex]{ \rm{d _{2} = kt _{2} }}[/tex]

[tex]{ \rm{d _{2} = (80 \times 6)}} \\ \\ { \boxed{ \boxed{ \rm{ \: \: d _{2} = 480 \: km \: \: }}}}[/tex]

Answer:

101.6

Step-by-step explanation:

The temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.

Given that,

The body temperature in Fahrenheit of a sheep is modeled by the equation,

[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]

where t is the number of hours.

Now, substitute t=3 into the equation;

[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]

[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]

Since, [tex]sin(\dfrac{\pi }{28} (- 6)) = - 0.5637[/tex]

Therefore, the temperature of the sheep when t=3 is:

[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]

[tex]T = 0.6 \times - 0.5637 + 101.6[/tex]

[tex]T = 101.24[/tex]

So, the temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.

Answer: 145%

Step-by-step explanation: It is 145% because all the squares represent 1% and each graph is 100%. One of the graphs are 100% shaded and the other is only 45% shaded. Adding these two percentages make 145%.

To solve that question we can think by the following way:

Using the fundamental principle of counting, we will find out that can be formed [tex]4\times 4 = 16[/tex] differents sequences (for example, AA, AG, TT, TG, CT...).

Know we know that, we can generalize. If I have [tex]n[/tex] elements and I must choose one of them [tex]t[/tex] times to do a sequence, the total number of sequence that I can form will be [tex]n^t[/tex].

In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is [tex]4\times 4\times 4\times ... \times 4[/tex] (29 times) [tex]= 4^{29}[/tex].

Therefore, there are [tex]4^{29}[/tex] DNA sequences with exactly 29 letters long.

I hope I've helped you. =D

Answer:

8/69

Step-by-step explanation:

1.6÷13.8

convert the decimal into fraction so 8/5 ÷ 13.8 and 8/5÷69/5 multiply by the reciprocal and reduce the number and you will get 8×1/69

Answer:

no solution

Step-by-step explanation:

to solve this we should first distribute

3 - 4x + 10 < -4x - 2 (fyi you need to multiply the negatives into the parenthesis)

and then you combine like terms

13 < -2

because 13 is always greater than -2, this statement will never be true

Answer:

Step-by-step explanation:

This inequality is false hence no solution

Hey there!

Guide

• 2 Negatives = [Positive]

• 1 positive & 1 negative = [Negative]

• 2 positives = [Positive]

• 1 negative & 1 positive = [Negative]

° So, this means that your answer most likely will equal a NEGATIVE number because you have 1 NEGATIVE (-3) number and 1 POSITIVE (“c” or 4.2) number.

-3c

= -3(4.2)

= -12.6

Therefore, your answer is: -12.6

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

4(x+1)=3x+10

4x+4=3x+1

4x-3x+10-4

x=6

Answer:

Since x = 6, the equation only has one solution.

Step-by-step explanation

You have to solve the equation first.

Let's solve your equation step-by-step.

4 ( x + 1 ) = 3x + 10

Step 1: Simplify both sides of the equation.

4 ( x + 1 ) = 3x + 10

( 4 ) ( x ) + ( 4 ) ( 1 ) = 3x + 10 (Distribute)

4x + 4 = 3x + 10

Step 2: Subtract 3x from both sides.

4x + 4 − 3x = 3x + 10 − 3x

x + 4 = 10

Step 3: Subtract 4 from both sides.

x + 4 − 4 = 10 − 4

x = 6

Answer:

x = 6

Answer:

y = x - 8

Step-by-step explanation:

7/7X - 8

the y intercept was the only tricky part

Answer:

f(x)=1x-8

Step-by-step explanation:

slope: 0-(-7)/ 8-1 = 7/7= 1

eg. (1,-7)

-7= 1 -y int.

y int. = 8

therefore:

f(x) = 1x-8

Step-by-step explanation:

the line passing through the points (-7, - 7) and (4,-7).

Slope: (-7+7) /(4+7) = 0/11 = 0

this is a horizontal line

through the points (4,7) and (4, -6).

slope: (-6-7) /(4-4) = -13/0 = oo

this is a vertical line

Answer:

Step-by-step explanation:

Answer: An unopened can of Diet Dr. Pepper is the least dense.

Step-by-step explanation:

For a solid object to float in a liquid, it must be less dense.

Let's associate the density of Diet Dr. Pepper with x, Dr. Pepper with y, and lake water with z.

Because of the above fact, x < z, and y > z.  Thus, x < z < y, and x < y.
