To find the distance between any points, we must use the equation
--> [tex]\sqrt{(y2-y1)^2+(x2-x1)^2}[/tex]
For the first question (3,-1) and (5,4), if we plug in the numbers, we get:
--> [tex]\sqrt{(4--1)^2+(5-3)^2} =\sqrt{5^2 + 2^2} =5.39 units[/tex]
For the second question (2,3) and (4,5), if we plug in the numbers, we get
--> [tex]\sqrt{(5-3)^2+(4-2)^2} =\sqrt{2^2+2^2} =2.83units[/tex]
For the third question (-5,7) and (8,5), if we plug in the numbers, we get
--> [tex]\sqrt{(5-7)^2+(8--5)^2} =\sqrt{(-2)^2+(13)^2} =13.15units[/tex]
For the fourth question (-2,4) and (3,-1), if we plug in the numbers, we get
--> [tex]\sqrt{(-1-4)^2+(3--2)^2} =\sqrt{(-5)^2+5^2} =7.07units[/tex]
Hope it helped!
Answer:
Bro above me is correct.
(3,-1) and (5,4) = 5.39
(2,3) and (4,5) = 2.83
(-5,7) and (8,5) = 13.15
(-2,4) and (3,-1) = 7.07

Khalid purchased 4 items at the dollar store. He was surprised that the total did not equal $4.00. Brian did not realize that the store required 5 1/2% sales tax. How much was Brian’s total bill including sales tax?
Answer:
B. $4.22
Step-by-step explanation:
51/2 % can be put into decimal form as 0.055
To find what 5 1/2% of $4 is you simply need to multiply 4 by 0.055
which makes $0.22
add that to $4 and you have your answer

1 + sin^4A ÷cos^4A = 1 + 2tan^2A.sec^2A
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
tan²x + 1 = sec²x
Consider the left side
[tex]\frac{1+sin^4A}{cos^4A}[/tex]
= [tex]\frac{1}{cos^4A}[/tex] + [tex]\frac{sin^4A}{cos^4A}[/tex]
= [tex]sec^{4}[/tex] A + [tex]tan^{4}[/tex] A
= (tan²A + 1)² + [tex]tan^{4}[/tex] A
= [tex]tan^{4}[/tex] A + 2tan²A + 1 + [tex]tan^{4}[/tex] A
= 1 + 2tan²A + 2[tex]tan^{4}[/tex] A ← factor out 2tan²A
= 1 + 2tan²A(1 + tan²A)
= 1 + 2tan²A sec²A
= right side , thus verified

Write an equation of the line that passes through the point (6, 3) and is perpendicular to y=-1/3x+ 12.
y=3x+12
y=x+5
y=-1/3x+5
y=-1/3x+12
Answer:
A: [tex]y=3x+12[/tex]
Step-by-step explanation:
To start we need to know what makes lines perpendicular. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.
Then, we need to understand the slope-intercept form of an equation. The slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope of the line and [tex]b[/tex] is the y-intercept. We also know that [tex]x[/tex] and [tex]y[/tex] represent points on the line.
Now, since our equation is already in the correct form, we can start with finding the opposite reciprocal of the slope. To do this, all we have to do is flip the fraction upside down and multiply by -1. This means that the opposite reciprocal of [tex]-\frac{1}{3}[/tex] would be [tex]\frac{3}{1}[/tex] which can be written as [tex]3[/tex].
Now, since we have a list of options and only one has the correct slope, we can safely choose option A.

Describe any patterns/relationships that you notice between the Powers of 10, the expressions, what they equal (standard form), or amount of zeros in the product. Try to use math vocabulary in your explanation below. You may use examples to support your response.
Answer:
The powers of 10 are things of the form:
10^n.
Where we assume that n is an integer number.
if is equal or larger than 0, then:
We add n zeros at the right of the 1.
so let's write some examples.
10^0 = 1 (we do not add any zero)
10^1 = 10 (we add one zero)
10^2 = 100 (we add two zeros)
...
Now, remember that x^-y = 1/x^y, then:
If n is smaller than zero, then we add n zeros at the left of the 1.
10^-1 = 1/10 = 0.1 (one zero at the left)
10^-2 = 1/100 = 0.01 (two zeros at the left).
Those relations will be useful to always know the exact dimensions of the powers of zero.
Now, we can give a more complete description knowing that:
x^a*x^b = x^(a + b)
Then if we have:
10^3*10^4 = 100*1,000 (and this may be hard to do)
But we can use the above relation:
10^3*10^4 = 10^(3 + 4) = 10^7
Then we know that we must add 7 zeros at the right of the 1.
And this will work for any integer powers of 10.

Answer:
[tex]p_1=2+ \sqrt{5}\\p_2=2- \sqrt{5}[/tex]
Step-by-step explanation:
A second-degree equation is often expressed as:
[tex]ax^2+bx+c=0[/tex]
where a,b, and c are constants.
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The equation to solve is:
[tex]p^2-4p=1[/tex]
We need to express the equation as mentioned above. The right side of the equation must be zero, so we subtract 1:
[tex]p^2-4p-1=0[/tex]
Now we have the values to solve the equation:
a=1, b=-4, c=-1
Applying the formula:
[tex]\displaystyle p=\frac{-(-4)\pm \sqrt{(-4)^2-4(1)(-1)}}{2(1)}[/tex]
[tex]\displaystyle p=\frac{4\pm \sqrt{16+4}}{2}[/tex]
[tex]\displaystyle p=\frac{4\pm \sqrt{20}}{2}[/tex]
Since 20=4*5:
[tex]\displaystyle p=\frac{4\pm \sqrt{4*5}}{2}[/tex]
Taking the square root of 4:
[tex]\displaystyle p=\frac{4\pm 2\sqrt{5}}{2}[/tex]
Simplifying by 2:
[tex]p=2\pm \sqrt{5}[/tex]
Two solutions are found:
[tex]\boxed{p_1=2+ \sqrt{5}}\\\boxed{p_2=2- \sqrt{5}}[/tex]
true or false 4. If the area of a rectangle is 6 m2, then the dimensions must be 2 meters by 3 meters.
Answer:
yes the answer is true
Step-by-step explanation:
the length of the rectangle is given 2 m
the breadth of the rectangle is given 3 m
so the area of the rectangle = length * breadth
= 2m*3m
=6m^2
hence proved

Stacey jogs every third day and swims every fourth day. If she jogs and swims on Monday, what is the next day of the week she will end up jogging and swimming.
Answer:
Saturday
Step-by-step explanation:
First we have to find the LCM of 3 and 4
It is 12, so we know that she will jog and swim every 12 days
This time was Monday, so 12 days after Monday will be the day she both jog and swims.
12 days after Monday is Saturday, so the next time she jogs and swims is Saturday.

(7x - 25)°
(4x + 2)°
▪ Answer:
x = 9
▪ Step-by-step explanation:
Hi there !
opposite angles
4x + 2 = 7x - 25
2 + 25 = 7x - 4x
27 = 3x
x = 27 ÷ 3
x = 9
Good luck !
Answer:
x = 9
Step-by-step explanation:
opposite angles
4x + 2 = 7x - 25
2 + 25 = 7x - 4x
27 = 3x
x = 27 ÷ 3
x = 9
There are 2 friends chasing one another. They are 80
feet apart. Caroline is chasing after Sam. Sam runs at
a speed of 22 feet per second and Caroline runs at a
speed of 31 feet per second. How many seconds will it
take for Caroline to catch Sam?
Answer:
8.9 seconds
Step-by-step explanation:
When caroline catches sam after some time lets say t
distance moved by Caroline will be 80 feet more than sam as they were 80 feet apart.
Given
Let the time taken by Caroline to catch sam is t seconds
distance covered by Caroline in t seconds = speed of caroline*t
distance covered by Caroline in t seconds = 31 * t
distance covered by Caroline in t seconds = 31t feet
distance covered by sam in t seconds = speed of sam*t
distance covered by sam in t seconds = 22 * t
distance covered by sam in t seconds = 22t feet
distance moved by Caroline will be 80 feet more than sam as they were 80 feet apart and caroline catches her in t seconds
thus,
distance covered by Caroline in t seconds = distance covered by sam in t seconds + 80 feet
31t = 22t + 80
subtracting 22t from both sides
=> 31t - 22 t = 80
=> 9t = 80
=>t = 80/9 = 8.9 seconds
Thus,
it will take 8.9 seconds for Caroline to catch Sam

if syn spends 15 minutes running, he burns 200 calories. how long would it take Syn to burn 150 calories?
Answer:
11.25minStep-by-step explanation:
In this problem, we first need to find the rate at which syn burns calories per minute
so in 15mins, he burns 200 calories
in 1 mins he will burn x
x= 200/15
x=13.33 calories per min this is the rate
So in one minute he will burn 13.33 calories
Now using the idea of rate=quantity/time
the rate=13.33
quantity=15 calories
time=?
time=quantity/rate
time=150/13.33
time=11.25min
Alternatively
(very fast approach)
if syn spend 15min to burn 200 cal
then he will spend x min to burn 150 cal
cross multiply
x=(150*15)/200
x=2250/200
x=11.25mins
