The ladder in a fire station is 29 feet (ft) tall. The ladder is anchored to the basement floor and the second floor ceiling. The basement floor is 12 feet below ground level. Identify the integers of the ends of the ladder below and above the basement floor

Answers

Answer:

top = 17ft

bottom = -12ft

Step-by-step explanation:

As seen in the badly drawn picture attached in this question we are trying to find the point at the top of the ladder and the point at the bottom of the ladder. As seen in the picture ground level has an altitude of 0 ft meaning that lower than this would be in the negatives. Since the basement floor is 12 feet below ground level then this point would be -12 ft. Now since we know that the ladder is 29ft tall we simply add this height to the basement floor value to get the value of the 2nd floor ceiling (top of the ladder).

29ft + ( -12ft) = 17ft

Therefore we can see that the point at the top of the ladder is 17ft.

y + 6 = 4/3(x - 2)

First, distribute the 4/3

y + 6 = 4/3x - 8/3

Subtract 6 from both sides.

y = 4/3x - 26/3

-26/3 is the y-intercept so start the graph at coordinate (0, -26/3)

After you plot the y-intercept, add 4 to they y-coordinate and 3 to the x-coordinate of the y-intercept to get the next point.

0 + 3 = 3

-26/3 + 4 = -14/3

The next point should be at (3, -14/3)

Add as many points as your professor requires.

Answer:

(0, -26/3)     (3, -14/3)

Step-by-step explanation:

y+6 = 4/3x - 8/3

y = 4/3x - 26/3

(0, -26/3)

-26/3 + 4 = -14/3

An object is moving at a speed of 63 centimeters every 2 days. Express this
speed in meters per hour. Round your answer to the nearest hundredth.

Answers

Given :

Distance covered by object , D = 63 cm .

Time taken to cover distance D , t = 2 days .

To Find :

The speed of object in m/s .

Solution :

First we will convert all units into m and hours .

D = 63 cm = 0.63 m .

[tex]t=2\ days =2\times 24\ hours =48\ hours[/tex] .

Now , speed is :

[tex]s=\dfrac{D}{t}\\\\s=\dfrac{0.63}{48}\ m/hours\\\\s=0.013\ m/hours[/tex]

Hence , this is the required solution .

(A) positive: (–2, 2)

(B) range: (–3, 4]

(C) domain: (–3, 3]

(F) increasing: (–3, –1)

What are the domain and range of the function?

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The vertical span of the range is from y > -3 to y = 3. The interval for this is [(-3, 3].

The horizontal range, from x > -3 to x = +4, represents the domain. This is represented by the interval [(-3, 4].

The graph decreases to the right, it gets smaller. There is no mention of the endpoints. The x values are in the range (-1, 4).

The graph is increasing where it goes up to the right. The endpoints are generally not included. The x-values are in the interval (-3, -1).

The region of the graph that is above the x-axis is positive. The interval contains x. (-2, 2).

The solution to the expression is x = 5.

We have,

Expression:

x³ - 125 = 0

This can be written as,

x³ = 125

Now,

Cube of 5:

5³ = 5 x 5 x 5 = 125

Now,

x³ = 5³

Cube cancels out on both sides.

x = 5

Thus,

The solution to the expression is x = 5.

At 8 a.m. the temperature was 56°F. By noon a storm had arrived, and the temperature was 43°F. Which describes the change in the temperature from 8 a.m. until noon?

Answers

Answer:

13°F

Step-by-step explanation:

Given that,

Initial temperature = 56°F

Final temperature, = 56°F

We need to find the change in temperature. It is equal to the difference between final temperature and the initial temperature. So,

[tex]\Delta T=T_f-T_i\\\\\Delta T=43^{\circ}F-56^{\circ} F\\\\\Delta T = 13^{\circ} F[/tex]

So, the change in temperature is 13°F.

Poonam is five times as old as Shalini. The sum of their ages is 72

Answers

Answer:

Shalini = 12

Poonam = 60

Step-by-step explanation:

Let p = poonams age

Let s = shalini's age

p = 5s

p+s = 72

Substitute the first equation into the second equation

5s+s = 72

Combine like terms

6s= 72

Divide by 6

6s/6 = 72/6

s = 12

p = 5s =5*12 = 60

Shalini = 12

Poonam = 60

A toothpaste company surveyed 36,219 customers about their favorite toothpaste flavor . The date will be used be help the company decide what flavors to continue making . To the nearest thousand, about how many customers were surveyed.

Answers

Answer:

To the nearest thousands; 36,000 customers were surveyed.

Step-by-step explanation:

Conversion of figures to the nearest thousand often requires rounding up digits that are not up to 5 in the place of hundreds to zero and rounding up the digits that are up to 5 in the place of hundreds to one, therefore, adding it to the value of the previous thousands.

From the given  question, to round up the number of customers surveyed in the company, we have the following:

since we are given the value to be 36,219

9 is in unit position

1 is in tens

2 is in hundreds

6 is in thousands

3 is in ten thousand

since the value of 2 in hundred is not up to 5, we round it up to zero, Then our value becomes 36,000 to the nearest thousand.
