When x = 1 then y equals

Sorry to be annoying again I just really suck at math and I haven't slept yet

Vesna [10]

Answer:

50.33 mi.

Step-by-step explanation:

GIVEN :-

Coordinates of :-

Home = (0 , 0)
School = (4 , 3)
Pizza place = (-8 , 2)
Movie Theater = (-4 , -6)
Park = (7 , -5)

TO FIND :-

Total distance travelled on Friday & Saturday.

GENERAL FORMULAE TO BE USED IN THIS QUESTION :-

Lets say there are two points A & B on a cartesian plane whose coordinates are (x₁ , y₁) & (x₂ , y₂).

Distance between A & B = $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

SOLUTION :-

According to question ,

On Friday , you -

leave school and go to pizza palace. Distance travelled from school to pizza palace = $\sqrt{(4 -(-8) )^2 + (3 - 2)^2} = \sqrt{(12)^2 + (1)^2} = \sqrt{145}$ ≈ 12.04 mi.
go to movie theater after pizza palace. Distance travelled from pizza palace to movie theater = $\sqrt{[(-4) -(-8)]^2 + (-6 - 2)^2} = \sqrt{(4)^2 + (-8)^2} = \sqrt{80}= 4\sqrt{5}$ ≈ 8.94 mi.
come back to your home after the movies. Distance travelled from theater to home = $\sqrt{[0-(-4)]^2 + (0 - 6)^2} = \sqrt{(4)^2 + (-6)^2} = \sqrt{52} = 2\sqrt{13}$ ≈ 7.21 mi.

⇒ On Friday , total distance travelled = 12.04 + 8.94 + 7.21 = 28.19 mi.

On Saturday , you -

go to park from your home. Distance travelled from home to park = $\sqrt{(7 -0 )^2 + (-5 - 0)^2} = \sqrt{(7)^2 + (-5)^2} = \sqrt{74}$ ≈ 8.6 mi.
go to school after going to park. Distance travelled from park to school = $\sqrt{(4 -7 )^2 + [3 - (-5)]^2} = \sqrt{(-3)^2 + (8)^2} = \sqrt{73}$ ≈ 8.54 mi.
go to home after playing basketball in school. Distance travelled from school to home = $\sqrt{(0 -4 )^2 + (0 - 3)^2} = \sqrt{(-4)^2 + (-3)^2} = \sqrt{25}$ = 5 mi.

⇒ On Saturday , total distance travelled = 8.6 + 8.54 + 5 = 22.14 mi.

∴ Total distance travelled on Friday & Saturday = 28.19 + 22.14 = 50.33 mi.

HELP ME:Malik deposited $1,050 in a savings account, and it earned $241.50 in simple interest after four years. Find the interes

MaRussiya [10]

To convert these numbers to a percent, divide the subset by the total, then multiply by 100.
$241.50 (subset) divided by $1,050 (total)
Is 0.23. Next, multiply the quotient (0.23) by 100 to get your answer.
0.23*100 = 23.
The interest rate would be 23%.

You want to know the opinions of American school teachers about establishing a national test for high school graduation. You obt

GaryK [48]

Answer: D) all American school teachers.

Step-by-step explanation:

In statistics, A population is a very large set of individuals or values that belong to a specified group established by researcher.

A sample is a subset of population that represents the entire population in research.

Given : We want to know the opinions of American school teachers about establishing a national test for high school graduation.

Clearly , by the above definition

Population = all American school teachers.

You obtain a list of the members of the National Education Association and mail a questionnaire to 2500 teachers chosen at random from this list.

sample = 2500 teachers chosen at random from this list.

Hence, the intended population is all American school teachers.

Thus , the correct answer is D) all American school teachers.
