Answers

Answer 1
the anwser is c took the test and got it right so hopefully that helps
Answer 2

Answer: The sample space showing the possible orders of the other three runners is

[tex]S=\{HFGI,HGFI,HIGF,HFIG,HGIF,HIFG\}[/tex]

Step-by-step explanation:

Since we have given that

Number of runners = 4

Four runners are as follows:

Fran, Gloria, Haley, and Imani.

Since Haley is the first runner in the relay,

So, Sample space showing the possible order of the other three runners.

[tex]S=\{HFGI,HGFI,HIGF,HFIG,HGIF,HIFG\}[/tex]

Hence, the sample space showing the possible orders of the other three runners is

[tex]S=\{HFGI,HGFI,HIGF,HFIG,HGIF,HIFG\}[/tex]

(f-g)(x)= -x^2+2x+8

Answer:

The required answer is: [tex]-x^2+2x+8[/tex]

Step-by-step explanation:

We have been given the two function:

[tex]f(x)=2x+1[/tex]

And [tex]g(x)=x^2-7[/tex]

We have to find (f-g)(x):

[tex](f-g)(x)=f(x)-g(x)[/tex]

[tex](2x+1)-(x^2-7)[/tex]

[tex]2x+1-x^2+7[/tex]

[tex]-x^2+2x+8[/tex]

We will get the quadratic expression after the prescribed operation been applied.

Hence, the required answer is: [tex]-x^2+2x+8[/tex]

Bob climbed down a ladder from his roof, while Rob climbed up another ladder next to him. Each ladder had 30 rungs. Thrir friend Jill recorded the following information about Bob and Rob: Bob Went down 2 rungs every second .Rob went up 1 rung every second . At some point , Bob and Rob were at the same height. Which rung were they on ?

Answers

Let H represent the height of the individuals in rungs and t represent the time in seconds that 
passes while they climb.
.
Bob starts at rung 30 and goes down at a rate of -2 rungs per second. So the equation for
Bob's height is:
.
H = -2*t + 30
.
Meanwhile, Rob starts at rung 0 and goes up at a rate of +1 rung per second. So the equation
for Rob's height is:
.
H = t + 0 = t
.
You are interested in finding the height (in rungs) where the two will be standing on
the same rung. Since the two heights are the same, we can set the right sides of our two
height equations equal. So we can say that:
.
-2*t + 30 = t
.

To solve this equation for t, first get rid of the 30 on the left side by subtracting
30 from both sides of the equation. This subtraction converts the equation to:
.
-2*t = t - 30
.
Next get rid of the t on the right side by subtracting t from both sides. The equation then
becomes:
.
-3*t = -30
.
Solve for t by dividing both sides of this equation by -3 to find that:
.
t = -30/-3 = 10 seconds
.
In 10 seconds Rob will have climbed to rung number 10 because he climbs at 1 rung per
second. And in 10 seconds at a rate of 2 rungs per second Bob will climb down 20 rungs. But 
Bob started on rung 30 so he will be at rung 10 also because 30 - 20 = 10.
.
Hope this helps you to understand the problem a little better.

Final answer:

The problem involves finding the time and the rung at which Bob and Rob meet. They both meet on the 10th rung after 10 seconds of Bob's descent and Rob's ascend on their ladders, moving at their respective rates.

Explanation:

In this problem, we are asked to find the rung at which both Bob and Rob meet. Each ladder has 30 rungs. Bob is descending from 30 rungs, moving down 2 rungs every second. Rob is ascending from 0 rungs, moving up 1 rung every second. To determine where they meet, we need to find the time at which the rungs they're on coincide.

Bob goes down 2 rungs per second, so in 't' seconds Bob will be on the 30 - 2t rung. Similarly, Rob goes up 1 rung per second, so in 't' seconds Rob will be on the t rung. They meet when 30 - 2t equals t. Solving this equation gives us that t equals 10 seconds.

So at 10 seconds, they meet & the rung they're on is t = 10. Hence, Bob and Rob meet on the 10th rung.

The cost of seeing a weekday show is 2/3 the cost of a weekend show. in one month, andy spent $42.50 for 4 weekday shows and 3 weekend shows. find the price of a weekday show and the price of a weekend show

Answers

 x = weekday shows
y = weekend shows

x = 2/3y
4x + 3y = 42.50

4(2/3y) + 3y = 42.50
8/3y + 3y = 42.50
8/3y + 9/3y = 42.50
17/3y = 42.50
y = 42.50 * 3/17
y = 127.50/17
y = 7.50

x = 2/3y
x = 2/3(7.50)
x = 15/3
x = 5

so weekday shows (x) cost $ 5 and weekend shows (y) cost $ 7.50

Answer:

x = weekday shows

y = weekend shows

x = 2/3y

4x + 3y = 42.50

4(2/3y) + 3y = 42.50

8/3y + 3y = 42.50

8/3y + 9/3y = 42.50

17/3y = 42.50

y = 42.50 * 3/17

y = 127.50/17

y = 7.50

x = 2/3y

x = 2/3(7.50)

x = 15/3

x = 5

so weekday shows (x) cost $ 5 and weekend shows (y) cost $ 7.50

prove the identity. show all work. tan(x-pi/4)=tanx-1/tanx+1

Answers

We used the tangent difference identity to rewrite the LHS in terms of [tex]\( \tan x \) and \( \tan \frac{\pi}{4} \)[/tex], then simplified to match the RHS, confirming the identity.

To prove the identity [tex]\( \tan(x-\frac{\pi}{4}) = \frac{\tan x - 1}{\tan x + 1} \),[/tex] we'll start with the left-hand side (LHS) and manipulate it to match the right-hand side (RHS).

LHS: [tex]\( \tan(x-\frac{\pi}{4}) \)[/tex]

Using the tangent difference identity, [tex]\( \tan(a - b) = \frac{\tan a - \tan b}{1 + \tan a \cdot \tan b} \)[/tex], we have:

[tex]\[ \tan(x-\frac{\pi}{4}) = \frac{\tan x - \tan \frac{\pi}{4}}{1 + \tan x \cdot \tan \frac{\pi}{4}} \][/tex]

Since [tex]\( \tan \frac{\pi}{4} = 1 \)[/tex], we can substitute:

[tex]\[ \tan(x-\frac{\pi}{4}) = \frac{\tan x - 1}{1 + \tan x \cdot 1} \][/tex]

[tex]\[ = \frac{\tan x - 1}{\tan x + 1} \][/tex]

This matches the RHS of the identity. Therefore, we have successfully proved the identity.

The inequality that represents the situation is 1*R + 4*D <= 64 which indicates that the total amount of ribbon used to make regular and deluxe barrettes should not exceed 64 yards.

Explanation:

Let's denote the number of regular barrettes as R and that of deluxe barrettes as D. Each regular barrette requires 1 yard of ribbon and each deluxe barrette requires 4 yards of ribbon. We know that Capricia has a total of 64 yards of ribbon. Therefore, we can create the inequality as follows:

What's the numerator for the following rational expression? G/h + 8/h = ?/h

Answers

We have the rational expression G/h + 8/h. Both fractions have the same denominator h so the denominator of their sum is obviously h. All we need to do is find the numerator. When 2 fractions have the same denominator (Which is necessary to add and subtract), the numerator of the answer is the sum of the numerators of the fractions we're adding. So the numerator of the answer is G+8. Of course, we can't add them because G is a variable and 8 is a number, so just leave it like that.

So G/h + 8/h = (G+8)/h

Hope this Helps! :)
G/h + 8/h = ?/h

As you can see, there is h is denominator on both RHS & LHS.
So, you can eliminate it & can consider all numerators as a whole at a time.
Then, it will be:
G+8 = G+8

So, your final answer is G+8

Answer:

x must be greater than or equals to 2

Step-by-step explanation:

Here we follow the rule , which says that , the term inside the square root must not be less than 0. It is because, square of any real number whether positive or negative always results in a positive real number. Hence , there can not be negative real number whose sqaure root exists.

we know that

Coplanar points are three or more points which lie in the same plane. Remember that a plane is a flat surface which extends without end in all directions. Any three points in 3-dimensional space determine a plane.

case a) points A, B, E

Any group of three points determines a plane

so

The points A,B,E are coplanar

case b) points A, B,C,E

The four points do not belong to the same plane
