Complete the equation of the line through (4,-8)(4,−8)left parenthesis, 4, comma, minu

Answers

Answer 1

Equation of a line is in the form y = mx+c, where m is the gradient and c is the y-intercept.

First step is to find the gradient.

m = (y2-y1)/(x2-x1)
= ( 5- -8)/(8-4) = 13/4

We have y = (13/4)x + c

Now we replace one of the coordinates to find c. Let’s replace (4,-8)

We have: -8 = (13/4)*4 + c

-8=13+c
c=-8-13= -21

Therefore, equation of line is:

y = (13/4)x - 21

Answer:

Step-by-step explanation:

Given function is,

f(x) = [tex]x\sqrt{x}[/tex]

We can rewrite this function as,

f(x) = [tex]x^{\frac{3}{2}}[/tex]

a). Domain of the function is [0, ∞)

Derivative of the function in this domain,

f'(x) = [tex]\frac{3}{2}x^{(\frac{3}{2}-1)}[/tex]

= [tex]\frac{3}{2}x^{\frac{1}{2}}[/tex]

Since, f'(x) > 0 in the interval [0, ∞)

Function is increasing in the interval [0, ∞)

b). For local maxima and local minima,

Second derivative of the function,

f"(x) = [tex]\frac{3}{2}(\frac{1}{2})x^{\frac{1}{2}-1}[/tex]

= [tex]\frac{3}{4}x^{-\frac{1}{2}}[/tex] > 0

So the function should have a local minima.

But the function is continuous in the interval x ≥ 0,

There is no local minima (only absolute minima).

c). Since, second derivative is undefined at x = 0,

There are no inflection points.

d). Since, f"(x) > 0 in the interval [0, ∞)

Concavity of the curve is UPWARDS.

If P(A) = .80, P(B) = .65, and P(A ∩ B) = .78, then P(B | A) =

Answers

Answer:

P(B | A) = 1.2

Step-by-step explanation:

Given

P(A) = .80P(B) = .65P(A ∩ B) = .78

To determine

P(B | A) = ?

Using the formula

P(B | A) = P(A ∩ B) / P(B)

= .78 / .65

= 1.2

Therefore,

P(B | A) = 1.2

A bird leaves its nest and travels 18 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after x hours.

a. What is the distance of the entire trip? (In miles)

b. How long does the entire trip take? (In hours and minutes and seconds)

Answers

9514 1404 393

Answer:

60 miles3 hours 40 minutes 0 seconds

Step-by-step explanation:

The relation between speed, distance, and time is ...

distance = speed × time

a) The distance the bird traveled downwind is ...

(18 miles/hour)(x hours) = 18x miles

3 miles per hour slower than 18 miles per hour is 15 miles per hour. So the distance in miles the bird traveled after x hours on the return trip is ...

15x = 18x -5

5 = 3x . . . . . . add 5 -15x

x = 5/3 . . . . . .divide by 3

Then the distance traveled downwind is ...

18x = 18(5/3) = 30 . . . . miles

and the time for the return trip is ...

(30 mi)/(15 mi/h) = 2 h . . . . . for the entire return trip

So, the entire round trip is 2×30 miles = 60 miles.

b) The time for the entire trip is ...

5/3 h downwind + 2 h return = 3 2/3 h = 3 hours 40 minutes 0 seconds

Angle 1 and Angle 2 are a linear pair. Angle 1=x-15, and angle 2=x+77. Solve for x then find the measure of each angle.

Answers

Answer: x=59, angle 1= 44˚, angle 2= 136˚

Step by step explanation:

Linear pairs add to make 180˚.

So angle 1 + angle 2= 180˚

Therefore x-15+x+77= 180

Add the x’s to get 2x
And then -15+77 to get 62.

So 2x+62=180
Subtract 62 to get 2x=118
Then divide by 2 to get x=59

Then substitute the x value into the angle equations

So angle 1 will be 59-15 which is 44˚
And angle 2 will be 59+77 which is 136˚

Round to two decimal places if necessary.Original price: $210.29Markdown: 78%The sale price is $ Whats for Lunch?Marcia Amidon LustedZachary Maxwell was tired of trying to explain to his parents why he wanted to bring lunch to school instead of eating hot lunch. They couldnt understand why he didnt want to eat the gourmet food described on the schools online menu, which sounded both nutritious and interesting. Zachary just couldnt convince them that the food wasnt as great as it sounded. So in the fall of 2011, he began sneaking a small video camera into the cafeteria at his school, to show his parents what the lunches were really like. Six months and 75 school lunches later, Zachary made a documentary film about his lunch called Yuck: A 4th Graders Short Documentary About School Lunch.Truth in Advertising?"The citys Department of Education says that its committed to providing delicious and nutritious meals through their food service program. But the lunch being served at my school was nothing like what they were advertising on their web site," Zachary, now 11, says in the documentarys trailer. "I told [my parents] thats not what they were actually serving me," he said. "But I dont think they believed me." For example, an "oven-baked pizza bagel with tricolor salad" was really nothing more than a slice of pizza and a wisp of lettuce. Sometimes there was no connection between the menu and what Zachary actually got. "Cheesy lasagna rolls with tomato basil sauce, roasted spinach with garlic and herbs" was, in reality, just a plastic-wrapped grilled cheese sandwich, all alone on a foam plate."When I came back home and showed them the footage, they were like, ugh!" Zachary said. His dad, an amateur filmmaker, started helping Zachary transform his video footage into a film. It won several awards, and Zachary also made appearances on television shows like Good Morning America.Not Perfect, But BetterLets face it: many times school lunches just arent going to taste as good as they sound. Students also complain that with lunches that follow the new school lunch guidelines, there just isnt enough food. Smaller portions, more fruits and veggies, and fewer calories leave some kids, especially teenagers, still hungry after eating their lunch. A group of students in Kansas even wrote a music video called "We Are Hungry," where they sing about their stomachs growling after lunch and how theyre collapsing on the sports field because they havent eaten enough.However, the new federal lunch guidelines do mandate meals that are better for students, with less sodium, more whole grains, fewer calories, and more fruits and vegetables, as well as skim or 1 percent milk. These are a definite improvement over school lunches of not that many years ago, which once stuck with fare like burgers, French fries, and chicken nuggets. Some schools even allowed fast food outlets like McDonalds and Pizza Hut to operate mini-restaurants in their cafeterias, or supply their products for students. Many schools have also reconsidered vending machines filled with sugary sodas, candy, and chips, replacing them with water and healthy snacks.The Lunch ForecastThe new school lunches are designed to help students eat better, and combat health problems like obesity in kids. Ideally, a healthy school lunch should also taste good ... or at least as good as the description on the menu. It should also keep students from taking a trip to the vending machine or a nearby convenience store as soon as lunch is over, because theyre still hungry. But will the lunches served in your cafeteria ever taste as good as a fast food burger or a gourmet meal cooked at home? You be the judge. Mention some leadership qualities of Adolf Hitler.
