What is an equation in point-slope form for the line that contains the points (-1, 4) and (11, -6)?

Answers

Answer:

The equation in point-slope form is [tex]y-4=-\frac{5}{6}(x+1)[/tex]

Step-by-step explanation:

Given points are;

(-1, 4) and (11, -6)

We will find the slope of the line through the given points.

Slope = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{-6-4}{11-(-1)}[/tex]

m = [tex]\frac{-10}{12}[/tex]

m = [tex]\frac{-5}{6}[/tex]

Point slope form of a line is given by;

[tex]y-y_1=m(x-x_1)[/tex]

Putting the point (-1,4) and slope in the equation

[tex]y-4=-\frac{5}{6}(x-(-1))\\y-4 =-\frac{5}{6}(x+1)[/tex]

Hence,

The equation in point-slope form is [tex]y-4=-\frac{5}{6}(x+1)[/tex]

What single decimal multiplier would you use to decrease by 1% followed by a 1% increase

Answers

Answer:

0.9999

Step-by-step explanation:

Original: 1

decrease by 1%: 1 * (1 - 0.01) = 0.99

followed by a 1% increase: 0.99 * ( 1 + 0.01) = 0.99 * 1.01 = 0.9999

PLZ HELP

Answers

answer : 226

difference : 5

‘0th’ term : 6

rule : 5n + 6

if n = 44

220 + 6 = 226

Answer:

a₄₄ = 226

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 16 - 11 = 21 - 16 = 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = 5 , then

a₄₄ = 11 + (43 × 5) = 11 + 215 = 226

a dream club charges $150 for the first month of membership, and $5 less each month after that. what is the total membership for a year? for 2 years?

Answers

Answer:

for a year it would be 90 dollars i think and for the second year i think it would be 30 because a year is 12 months and every month they take away 5 so 12x5 is 60 so 150 minus 60 is 90 and for the second year 90 minus 60 is 30

Ginger buys lunch at school every day. She always gets
pizza when it is available. The cafeteria has pizza about
80% of the time.
Ginger runs a simulation to model this using a random
number generator. She assigns these digits to the possible
outcomes for each day of the week:
Let 0 and 1 = no pizza available
• Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available ​

Answers

Answer:

The estimated probability that Ginger will eat a a pizza everyday of the week is;

D. 8/10 = 80%

Step-by-step explanation:

The given parameters are;

The frequency with which Ginger buys launch = Everyday

The percentage of the time the cafeteria has pizza out = 80%

The outcome of 0 and 1 = No pizza available

The outcome of 2, 3, 4, 5, 6, 7, 8, and 9 = Pizza available

Therefore, we have the;

Group number  [tex]{}[/tex]                          Percentage of time pizza available

1                     [tex]{}[/tex]                          80%

2                     [tex]{}[/tex]                          80%

3                     [tex]{}[/tex]                          80%

4                     [tex]{}[/tex]                          80%

5                     [tex]{}[/tex]                          40%

6                     [tex]{}[/tex]                          100%

7                     [tex]{}[/tex]                          80%

8                     [tex]{}[/tex]                          100%

9                     [tex]{}[/tex]                          80%

10                     [tex]{}[/tex]                          80%

Therefore, the sum of the percentages outcome the days Ginger eats pizza = 0.8 + 0.8 + 0.8 + 0.8 + 0.4 + 1 + 0.8 + 1 + 0.8 + 0.8 = 8

The number of runs of simulation = 10 runs

The estimated probability that Ginger will eat a a pizza everyday of the week = (The sum of the percentages outcome the days Ginger eats pizza)/(The number of runs of simulation)

∴ The estimated probability that Ginger will eat a a pizza everyday of the week = 8/10

2) Solve each problem with right angle at C:.
a) Find all sides and angles when B = 67º and c=16.
b) Find all sides and angles when b= 2 and c=6

Answers

Answer:

Step-by-step explanation:

a.)

<A = 90 - 67 = 23*      A = (a^2 + 14.72^2 = 16^2) = a = 6.25

<B = 67*                      B = (sin67 = b/16) = sin67*16 = 14.73

<C = 90*                      C = 16

b.)

a = (a^2 + 2^2 = 6^2) = a = 5. 66         <A = (cosA = 2/6) = 70.53*

b = 2                                                      <B = 90-70.53 = 19.47*

c = 6                                                      <C = 90*

the equation of slope is (y2-y1)/(x2-x1)

here are the points given: (0,5), (2,10)

let's label the points:

x1=0

y1=5

x2=2

y2=10

now substitute into the equation (m is the slope)

m=(10-5)/(2-0)

subtract

m=5/2

the slope is 5/2

Answers

the answer is 6 years i know this because i made this problem

Maya will have $800 in her saving account after 31.6 years.

Function representing the amount of money in Maya's saving account,

[tex]A(t)=500(1.015)^t[/tex]

Here, [tex]A(t)[/tex] = the final amount

[tex]500=[/tex] Initial amount

[tex]t=[/tex] Duration of investment

If the final amount in her saving account is $800,

Substitute the final amount as $800.

[tex]800=500(1.015)^t[/tex]

[tex](1.015)^t=\frac{800}{500}[/tex]

[tex](1.015)^t=1.6[/tex]

[tex]\text{log}(1.015)^t=\text{log}(1.6)[/tex]

[tex]t[\text{log}(1.015)]=\text{log}(1.6)[/tex]

[tex]t=\frac{\text{log}(1.6)}{\text{log}(1.015)}[/tex]

[tex]t=31.57[/tex]

[tex]t\approx31.6[/tex] years

        Therefore, Maya will have $800 in her saving account after 31.6 years.
