Write the slope-intercept form of the equation that is described below.
Through (3, 3) and perpendicular to y = 14x − 2
What is the equation?
Answer:
y = -¹/₁₄x + 3³/₁₄Step-by-step explanation:
If two lines are perpendicular then the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 14x - 2 ⇒ m₁=14
14×m₂ = -1 ⇒ m₂ = -¹/₁₄
The line y=-¹/₁₄x+b passes through point (3, 3) so the equation:
3 = -¹/₁₄×3 + b must be true
3 = -³/₁₄ + b
b = 3³/₁₄
Therefore equation in slope-intercept form:
y = -¹/₁₄x + 3³/₁₄

Kathryn's water bottle holds 20.25 ounces. Her doctor told her to drink half her body weight in ounces of water. Kathryn weighs 121.5 pounds. How many water bottles will she have to drink? (There is no convesion required from ounces to pounds)
Answer: She have to drink 3 bottles of water.
Step-by-step explanation:
Given: Weight of Kathryn = 121.5 pounds
half of her weight = [tex]\dfrac{121.5}{2}=60.75\text{ pounds}[/tex]
So, she need to drink 60.75 pounds of water.
Kathryn's water bottle holds 20.25 ounces.
Number of water bottles she need to drink = (half of her weight) ÷ (Capacity of bottle)
[tex]=\dfrac{60.75}{20.25}\\\\=\dfrac{6075}{2025}\\\\=3[/tex]
Hence, she have to drink 3 bottles of water.

What is the square root of negative one hundred
Answer:
10i
Step-by-step explanation:
The square root of negative 100 is not equal to 10. If 10 was the square root of negative 100, then 10 squared would be equal to negative 100. But in fact, 10 squared is 10*10, which is obviously (positive) 100, not negative 100.
To determine the actual value of the square root of negative 100, we can proceed as follows:
Let s be the square root of negative 100.
Then s^2 = -100.
So s^2 = 100×(-1) = (10^2)×(i^2) =10×10×i×i = 10×i×10×i =(10i)^2.
So s = 10i.
So the square root of negative 100 is equal to 10i.
Note that the square of -10i is also equal to negative 100. 10i is the principle square root of negative 100.
Answer:
10i
Step-by-step explanation:
Since, it's a negative square root you have to use imaginary numbers to make it solvable. Hope this helps! :)

The table below represents a linear function f(x) and the equation represents a function g(x):
х f(x)
-1 -5
0 -1
1 3
g(x)
g(x) = 2x - 7
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
(6 points)
Part B: Which function has a greater y-intercept? Justify your answer. (4 points)
(10 points)
Answer:
Please check the explanation.
Step-by-step explanation:
Part a)
Finding the slope of f(x)
Given the table of the function f(x)
x f(x)
-1 -5
0 -1
1 3
Finding the slope using the formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)[/tex]
[tex]m=\frac{-1-\left(-5\right)}{0-\left(-1\right)}[/tex]
[tex]m=4[/tex]
Thus, the slope of the function f(x) = 4
Finding the slope of g(x)
We know the slope-intercept form of a linear function is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Given the function
[tex]g(x) = 2x-7[/tex]
comparing with the slope-intercept form
y = mx+b
The slope of the function g(x) = 2
Thus, we conclude that:
The slope of the function f(x) = 4The slope of the function g(x) = 2Hence, the slope of f(x) is greater.
Part b)
Finding the y-intercept form of f(x)
We know that the y-intercept can be determined by setting x = 0 and determining the corresponding y-value.
From the table,
It is clear at x = 0, y = -1
Hence, the y-intercept of the function f(x) = -1
Finding the y-intercept form of g(x)
Given the function
[tex]g(x) = 2x - 7[/tex]
comparing with the slope-intercept form (y = mx+b)
[tex]y = mx+b[/tex]
where b is the y-intercept
Hence, the y-intercept of g(x) = b = -7
Thus, we conclude that:
The y-intercept of the function f(x) = -1The y-intercept of the function g(x) = -7Hence, the y-intercept of f(x) is greater.

What is the relationship between cos(90degrees) and cos(-90°)?
Answer:
The relationship between the two is that they are equal.
Step-by-step explanation:
Since y = cosx is a even function, that means that cosx = cos(-x). Therefore, cos 90 degrees = cos -90 degrees.
We can also test this out:
cos 90 = 0
cos -90 = cos 270 = 0
Therefore, this came to the same conclusion as our first solution.

John will covers 4 km distance in 28 minutes.
What is Rate of change?
A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.
Here, it is given that John takes 45 minutes to run 4 miles and is known that :
1 mile ≈ 1.61 km
that is for,
4 mile ≈ 6.44 km
John covers 6.44 km in 45 minutes, John will cover 4 km in :
6.44 km ⇒ 45 minutes
1 km ⇒ 45/6.44 minutes
4 km ⇒ 4 x (45/6.44) minutes ≈ 28 minutes
Therefore, John will covers 4 km distance in 28 minutes.

Bella earned $216 in interest after 4 years on a principal of $1,500. What is her interest rate?
Answer:
R = 148.6111%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/4)((1500/216) - 1) = 1.48611111
r = 1.48611111
Converting r decimal to R a percentage
R = 1.48611111 * 100 = 148.6111%/year
The interest rate required to get a total amount, principal plus interest, of $1,500.00 from simple interest on a principal of $216.00 over 4 years is 148.6111% per year.
Answer: 3%
Step-by-step explanation:
216 / 1500 = 14.4
14.4/ 48 months = .003
.003 x 100 = 3%
Tienes 12 personas Todas pesan exactamente lo mismo Menos 1 persona que pesa un poco más o un poco menos Dispones de una balanza y puedes pesar 3 veces Quien es el que pesa distinto
Answer:
El que pesa distinto es aquel que causa un desnivel en la balanza.
Step-by-step explanation:
Sabemos que una balanza tiene dos lados en los cuales podemos poner peso, si la balanza está equilibrada, ambos lados están a la misma altura, de lo contrario, habrá un desnivel entre ambos lados.
Puesto que solo podemos emplear la balanza 3 veces, debemos crear tres grupos de cuatro personas, que dentro de cada una cada mitad, conformada por dos personas, es colocada en un lado de la balanza. Si la balanza está equilibrada, entonces todo ese grupo está integrado por personas del mismo peso, pero si esta desequilibrada, una persona de alguno de los dos subgrupos.
En ese caso, se procede a sacar a dos personas, una por cada lado de la balanza, si el desbalance desaparece, entonces alguna de las dos personas que salió tiene un peso distinto, pero si el desbalance persiste, entonces es causante del desbalance se encuentra en aún en la balanza.
En conclusión, el que pesa distinto es aquel que causa un desnivel en la balanza.

A consumer advocate group selects a random sample of 205 snow foods in find 174 of them contain more what is indicated on the snacks nutritional information. Create a 90% confidence interval for the population proportion for a snack foods that contain more fat grams and was indicated on the snacks nutritional information
Answer: (0.809, 0.891)
Step-by-step explanation:
Let p = population proportion for a snack foods that contain more fat grams and was indicated on the snacks nutritional information .
As per given , we have
Sample size : n= 205
Sample proportion: [tex]\hat{p}=\dfrac{174}{205}\approx0.85[/tex]
z-value for 90% confidence = 1.645
Confidence interval for p: [tex]\hat{p}\pm z^* \sqrt{\dfrac{p(1-p)}{n}}[/tex]
[tex]0.85\pm (1.645)\sqrt{\dfrac{(0.85)(1-0.85)}{205}}\\\\=0.85\pm (1.645)\sqrt{\dfrac{0.85\times0.15}{205}}\\\\= 0.85\pm (1.645)\sqrt{0.000621951219512}\\\\=0.85\pm0.041\\\\=(0.85-0.041,\ 0.85+0.041)\\\\= (0.809,\ 0.891)[/tex]
Hence, the required confidence interval = (0.809, 0.891)
Find the distance, midpoint, and slope of line AB (-2,-1) and B(6,3)
Answer:
The correct answer is (2,1)
Step-by-step explanation:
The distance, midpoint, and slope are 4√5 , (2 , 1) , 1/2 respectively.
What are the distance, midpoint, and slope between two points?For any two points A( x₁ , y₁ ) B( x₂, y₂) the distance, midpoint, and slope are given by: 1) [tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
2) M(x , y) = { (x₁ + x₂)/2 , (y₁ + y₂)/2 }
3) m= y₂ - y₁ / x₂ - x₁
Given here the points A(-2,-1) and B(6,3)
substituting the values we get,
1) [tex]d = \sqrt {\left( {-2- 6} \right)^2 + \left( {-1 - 3} \right)^2 }[/tex]
[tex]d = \sqrt {\left( {8 } \right)^2 + \left( {4 } \right)^2 }[/tex]
[tex]d = \sqrt {\left( 80{ \right)^ }[/tex]
[tex]d =4\sqrt {\left5 }[/tex]
2) M(x , y) = { (-2 + 6)/2 , (-1 + 3)/2 }
= (2 , 1)
3) m = { (6 - (-2) / (3 - (-1)) }
= 1/2
Hence, distance, midpoint, and slope are 4√5 , (2 , 1) , 1/2 respectively.

K is between J and L. JK = 3x – 5, and KL = 2x + 1. IfJL = 16, what is JK?
A. 7
B. 8
C. 9
D. 13
Answer:
If JL = 16, we will get JK = 7
Option A is correct option.
Step-by-step explanation:
We are given:
K is between J and L
JK = 3x – 5, and KL = 2x + 1.
IfJL = 16, what is JK
We know that K is between J and L it means it divides JL into JK and KL equally or we can say that adding JK and KL we can get JL
So, We can write:
[tex]JL = JK + KL\\16=3x-5+2x+1[/tex]
Solving the expression we can find first value of x and then value of JK
[tex]16=3x-5+2x+1\\16=5x-4\\16+4=5x\\20=5x\\x=\frac{20}{5}\\x=4[/tex]
So, we get x = 4
Now, put the value of x in JK=3x-5 to get value of JK
[tex]JK = 3x-5\\JK=3(4)-5\\JK = 12-5\\JK=7[/tex]
So, if JL = 16, we will get JK = 7
Option A is correct option.
