What of the following lines is perpendicular to the line passing across the points (1,1) and (-5,-6)?
y = 6/7x + 1
y = -6/7x + 1
y = -6/7x - 1
y = 6/7x - 1
Answers
(-6-1)/(-5-1) = -7/-6 = 7/6
Perpendicular = opposite sign and reciprocal slope
Slope would be -6/7
It would be anything with slope of -6/7
find the slope given the points (-5 -3) and (2 4)
Answers
rise = 7
run = 7
7/7 = 1
Answer:
1
Step-by-step explanation:
The equation [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1}}[/tex], the points are (-5, -3) and (2, 4), so to know which is which just do it by order, so in this case [tex]y_{1} = 4, y_{2} = -3, x_{1} = -5, x_{2} = 2[/tex] basically like i said, just in order.
So let's separate the equations into 2 for now:
[tex]y_{2} - y_{1}[/tex] = 4 - (-3) = 4 + 3 = 7
[tex]x_{2} - x_{1}[/tex] = 2 - (-5) = 2 + 5 = 7
So put it together into the fraction and it's 7/7 which is 1, so the slope is 1
The sum of x and y equals 26.

Answers
Answer:
A. 86.64%
B. 80
C. y(t)= 80[tex]e^{0.8664t}[/tex]
D. y(5.5) = 9388
E. y(t) = 8134 bacteria for every hour
F. 8.28 hours
Step-by-step explanation:
a. The bacteria count after 4 hours y(4) = 2560
The bacteria count after 12 hours y(12) = 2621440
equation 1: ye^4k = 2560
equation 2: ye^12k= 2621440
divide (2) by (1),
e^8k = 1024
Taking ln both sides:
ln(e8k ) = ln(1024)
8k = 6.931
k=0.8664 // after dividing both sides by 8
rate of growth k% = 0.8664*100 = 86.64%
b. substituting for k in equation 2:
ye^4*0.8664 = 2560
Initial bacteria count y(4) = 80
c. y(t)= 80e^0.8664t
d. the number of bacteria after 5.5 hours => y(5.5) = 80[tex]e^{0.8664(5.5)}[/tex] ≈ 9388
e. y'(5.5) = 80*0.8664e^0.8664(5.5) = 69.31e^0.8664(5.5) = 8134
f. for bacteria population = 104000
where ye^0.8664t = 104000
y = 80
80e^0.8664t = 104000 //divide both sides by 80
e^0.8664t = 1300
ln(e^0.8664t = ln(1300)
t = 7.17 / 0.8664 = 8.28 hours

Vertex:
I need this answered ASAP please !
Answers
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )

Emma poured 40 fl oz. of grape juice equally into 5 cups. How much grape juice does each cup contain?
fl oz. per cup ?
Answers
Answer:
The correct answer is 8 fluid ounces per cup.
Step-by-step explanation:
To solve this problem, we need to divide the total amount of grape juice that Emma has (40 fl oz) by the number of cups she is pouring the juice into (5).
40 oz total/5 cups = 8 oz/cup
Therefore, each cup contains 8 fl oz.
