Hello there! The lines between the a are absolute value symbols, and absolute value symbols are always positive. They are the distance a number is away from 0. We are looking at the values less than 3, so this is definitely not an or statement. C and D are eliminated. The compound inequality would be -3 ≤ x ≤ 3. A is the answer choice that fits this. The answer is A.

Answer 2

Hello again!

|a| ≤ 3

Solve for the absolute value

We know either a ≤ 3 and a ≥ -3

So we have a ≤ 3 and a ≥ -3

Thus,

The correct answer is option A

we know that In right angle triangle c^2 = a^2 + b^2.
19^2 = 3^2 + b^2
b = (361 - 9)^1/2 = 18.761663039294
Now for angles
sin(A) = a/c = 3/19
A = sin{-1}(3/19) = 9.0847202873911
A = 9.0847202873911
sin(B) = b/c = 18.761663039294 / 19

Two competing cable companies have recently restructured their payment plans. Clear TV requires a $30 activation fee and charges $75 per month for their basic plan. Link TV requires no activation fee and charges $82.50 per month for their basic plan. When will the two plans be equal in cost?

Answers

Clear TV:
Activation fee = $30
Monthly charge = $7

Link TV:
Activation fee = $0
Monthly Charge = $82.50

Let x be the number of month that the two cost will be equal

30 + 75x = 82.5x
82.5x - 75x = 30
7.5x = 30
x = 30 ÷ 7.5 = 4 months

The two plans will be of equal cost after 4 months.

when n=0, d(n)=690. This is the y-intercept
All the functions given in the options are linear functions in the form y=mx+b, then we must find a function with independent term (y-intercept) b=690
The functions with b=690 are the first and third option.

For the slope (m), we can calculate it with 2 points of the table:
n1=0, d(n1)=690
n2=2, d(n2)=560

m=[d(n2)-d(n1)] / (n2-n1)
m=(560-690) / (2-0)
m= (-130) / 2
m=-65

Then the function must be:
d(n)=mn+b, m=-65, b=690
d(n)=-65n+690

Answer: Third option d(n)=-65n+690

How use zero product property to solve equations

Answers

The zero product property says that A*B = 0, then A = 0 or B = 0
In words: if two numbers multiply to 0, then one (or both) of the values must be zero.

So in terms of algebra, if we had
-0.2*(x-1.9)*(x-3.5) = 0
then
x-1.9 = 0 or x-3.5 = 0

Now solve each individual equation for x
x-1.9 = 0
x-1.9+1.9 = 0+1.9 ... adding 1.9 to both sides
x = 1.9

x-3.5 = 0
x-3.5+3.5 = 0+3.5 .... adding 3.5 to both sides
x = 3.5

The two solutions are x = 1.9 or x = 3.5

These two x values, when plugged into f(x), will make f(x) = 0
These are the x intercepts because this is where the graph crosses the x axis.
Note: "root" is another term for "x intercept"

A ball is thrown into the air from the edge of a 48 foot cliff so that it eventually lands on the ground. The graph below shows the height, y, of the ball from the ground after x seconds.

For which interval is the ball’s height always decreasing?

A. 48 B.0 C.2.5 D.146

Answers

the answer should be C, 2.5<x<5.5

2.5 < x < 5.5 seconds is the time interval when ball's height always decreasing.

What is time interval?

" Time interval is the division of time into small equal intervals to have a proper observation of any data."

According to the given graph,

x represents time in seconds along x-axis

y represents height in foot of the ball along y-axis

As per observation,

Height of the ball increasing from 48 to 146 in the time interval

0< x < 2.5.

Height of the ball decreasing from 146 to 0 in the time interval 2.5< x < 5.5.

Hence, we conclude that 2.5 < x < 5.5 seconds is the time interval when ball's height always decreasing.

Find the length of the side labeled x round to the nearest 10th

Answers

Trig problem here. We have 2 right triangles, the one on the left and on the right. They share one side. To find the length of this side, look at the left triangle. The hypotenuse is 44 and theta is 25, and since cos(theta)=adjacent/hypotenuse, cos(25)=adjacent/44 therefore the sidelength is 44cos(25). We are looking for x and now have an angle and a side for the righthand side right triangle so because tan(theta)=opposite/adjacent, tan(34)=opposite/(44cos(25)) therefore the opposite side is 44*cos(25)*tan(34)

You can solve for x by using trigonometry. However, only the angle opposite to x has been given. In order to get another length, find the altitude of the triangle. Use the length of the left side given to set up an equation like this. Let "y" equal the altitude temporarily.
Cos. 25 = y/44
Cos. 25 x 44 = y
0.9063 x 44 = y
39.8772 = y

Now that we have the altitude you can set up another equation for x.
Tan. 34 = x/39.8772
Tan. 34 x 39.8772 = x
0.6745 x 39.8772 = x
26.8971714 = x

Final Answer: x is approximately 26.9

Answers

Hey there :)

We know that the sum of all 3 angles in a triangle is 180°

Two angles are given to be 77° and 62°

We can find the 3rd angle by:
77 + 62 + x = 180 ( x is the angle to be found, you can use any variable, if not given)
180 - ( 77 + 62 ) = x

One angle of atriangle measures 12 degrees. the second angle's measurements is five times the third. what is the measure of the third angle

Answers

28 degrees. This is because the first angle is 12 degrees, the third is x degrees and the second is 5x. You know that in a triangle the angles add up to 180 degrees so 12 + 5x + x = 180. Then you get 6x =168 and x =28 degrees. (**x being the thrid angle**)

The measure of the third angle is; 28 degrees.

How does an angle form?

An angle requires two straight line/ line segments/rays, such that they're connected on one of their endpoints.

The point of their joint is called vertex of that angle.

Those two line segments forming it are called arms of that angle.

The angle is the degree of rotation that it will take for the moving side to go from initial side to the position it is currently on.

Let the third angle be x

Given that One angle of a triangle measures 12 degrees. the second angle's measurements is five times the third.

We know that in a triangle the angles add up to 180 degrees.

so, 12 + 5x + x = 180.

Then we get

6x =168

x =28 degrees.

There are three consecutive odd integers. Three times the largest is seven times the smallest. What are the integers?

Answers

Hello there!

This is how I would map out this problem...

First I would represent the smallest integer with the variable x. Since they are consecutive odd integers, add 2 to the middle integer and add 4 to the largest.

smallest: x
middle: x+2
largest: x+4

Now we need to find a way to solve for x. Since 3 times the largest is 7 times the smallest, we can set up an equation like this...
3(x+4)=7x

Now solve it!
3(x+4)=7x
3x+12=7x
12=4x
x=3

Now let's go back to our original data...
smallest: x
•Since the smallest is x, that means the smallest is going to be 3.
middle: x+2
•since the middle one is x+2, plug in 3 for x and we get 5.
largest: x+4
•since the largest is x+4, plug in 3 for x and we get 7.

This means the answer is...
Smallest: 3
Middle: 5
Largest: 7

A ball is thrown straight up with a initial velocity of 56 feet per second . The height , h , of the ball t seconds after it is thrown is given by the formula h(t)=56t-16t^2 . What is the maximum height of the ball?

Answers

Formula: H(t) = 56t – 16t^2

H(t) = - 16t^2 + 56t

A. What is the height of the ball after 1 second? H (1) = 56(1) – 16(1) ^2 = 40 pt.

B. What is the maximum height? X = - (56)/2(- 16) = 1.75 sec h (1.75) = 56(1.75) – 16(1.75) ^2 h (1.75) = 49ft.

C. After how many seconds will it return to the ground? – 16t^2 + 56t = 0 - 8t =0 t = 0

- 8t (2 + - 7) = 0 2t – 7 = 0 t = 7/2 Ans: 3.5 seconds

The maximum height achieved by the ball is 49 meters at time t = 7/4 seconds.

What is time dependent function?

The time dependent function is the function whose values vary with change in time. For example - f(t) = 3t + 5.

Given is a ball is thrown straight up with a initial velocity of 56 ft/s. The height (h) , of the ball (t) seconds after it is thrown is given by the formula h(t) = 56t - 16t²

The given function is -

h[t] = 56t - 16t²

Now, for maximum height -

dh/dt = 0

d/dt ( 56t - 16t²) = 0

d/dt (56t) - d/dt (16t²) = 0

56 - 16 d/dt (t²) = 0

56 - 16 x 2t = 0

56 = 32t

t = 56/32

t = 7/4 seconds

Now, at t = 7/4 seconds, the height is maximum. Substituting the value

t = 7/4 seconds, we get -

h(7/4) = 56 x 7/4 - 16 x 49/16

h(7/4) = 14 x 7 - 49

h(7/4) = 98 - 49

h(7/4) = 49 meters

Therefore, the maximum height achieved by the ball is 49 meters at time t = 7/4 seconds.
