Answer:
[tex]x=\frac{-5+\sqrt{33} }{2}[/tex] and [tex]x=\frac{-5-\sqrt{33} }{2}[/tex]
Step-by-step explanation:
x = [-b±√(b²-4ac)]/2a
x = [-(-5)±√((-5)²-4(1)(-2))]/2(1)
x = [5±√(25+8)]/2
x= [-5±√(33)]/2
Therefore:
[tex]x=\frac{-5+\sqrt{33} }{2}[/tex] and [tex]x=\frac{-5-\sqrt{33} }{2}[/tex]
Part A: explain why x coordinates of the points where the graphs of the equations y=4^x and y=2^(x-1) intersect are the solutions of the equation 4^x=2^(x-1). Part B: Make tables to find the solution to 4^x=2^(x-1). Take the integer values of x between -4 and 4. Part C: How can you solve the equation 4^x=2^(x-1) graphically?
9514 1404 393
Explanation:
A. The given equation will have a solution when the value of x makes the left-side expression equal to the right-side expression.
The value of the left-side expression for a given value of x is the y-value of y=4^x. The value of the right-side expression for a given value of x is the y-value of y=2^(x-1). The left-side expression will be equal to the right-side expression for a given value of x when the graph of y=4^x and the graph of y=2^(x-1) have the same y-value. That is, the graphs will be of the same point for that x-value. That is what we mean when we say the curves will intersect at that point.
The x-coordinate of the point of intersection is the value that makes the expressions equal, hence it is the solution to the equation.

B. The tables are included in the first attachment. We have used f(x) to represent the left-side expression, and g(x) to represent the right-side expression.
__
C. As described in Part A, the graphs will cross at the solution point. Hence the equation can be solved graphically by graphing the left-side expression and the right-side expression and seeing where the graphs cross. (That is at the point (-1, 0.25) on the attached graph.)
Alternate graphical method
The solution can also be found graphically by graphing the difference of the expressions: y = 4^x -2^(x-1). This difference will be zero at the value of x that makes the two expressions equal. That is, the x-intercept of the graph of this difference will be the solution value. The second attachment shows this sort of graphical solution. (It works nicely because many graphing calculators will display the value of the x-intercept.)
Ms.Hanna goes bowling with her friends. The bowling shoe rental for the group cost $22. Each game the group bowls cost $7.25.
1) Write an equation for the total cost c of the outing relating to the number of games played g.
2) How much will it cost to bowl 3 games?
Answer:
7.25x + 22
Step-by-step explanation:
I believe that this equation relates to the slope-intercept form, so we know that for every game the group bowls the cost will increase by 7.25. We also know that 22$ is a set rate, therefore it will not change as they continue to bowl. So we add the x to 7.25 because it represents the slope in this situation, and 22 is set.

Six less than the product of a number n and 1/5 is no more than 99
Answer:
(n * ⅕) - 6 ≤ 99
Step-by-step explanation:
Translating the word problem into an algebraic expression, we have;
(n * ⅕) - 6 ≤ 99
Opening the bracket, we have;
n/5 - 6 ≤ 99
Rearranging the equation, we have;
n/5 ≤ 99 + 6
n/5 ≤ 105
Multiplying both sides by 5, we have;
5 * n/5 ≤ 105 * 5
n ≤ 525

Can anyone give me some advices for my sis cause she is going to high school soon and I'm worried- even tho she is older then me, she is Autism and ofc I'm worried-
Don't worry I'm sure there'll be great people that would love to be friends with her!, you can also try to call everyday after she finishes her classes^^
Step-by-step explanation:
Advice;
Talk to her, let her know of the things she could be facing, yes we can give her as much advice as needed but it won't stop her from facing other rude teenagers.If she has a temper you guys should come up w coping mechanisms to use during school when she'll be alone. It's good practice to growing up.Ask for a tour around the school, it'll help her be more aware of her surroundings when she starts to attend.If she's nervous about entering a whole different nd new place it's fine, assure her it's going to be okay it'll just be a little adjustment.Advice for you; ( I know it wasn't asked of )
Calm down. Don't stress, I mean I know you're gonna, she's your sister but worrying about her is just gonna be a whole other problem you don't need. She's fine, she'll be fine, you don't want her to see you worry nd make her feel the same way, right?Alright, hope this was helpful! Need a little more insight? Feel free to ask.

Proper angle for a ladder is about 75° from the ground. Suppose you have a 10 foot ladder. How far from the house should you place the base of the latter? Round to the nearest hundredth
Answer:
The base of the ladder is 2.58 m.
Step-by-step explanation:
Given that,
The angle of elevation for a ladder from the ground is 75°.
The length of a ladder, H = 10 foot
We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,
[tex]\cos\theta=\dfrac{B}{H}\\\\B=H\times \cos\theta\\\\B=10\times \cos(75)\\\\B=2.58\ m[/tex]
So, the base of the ladder is 2.58 m.
To start planning the rooms' floor plans, you draw them each to scale on large sheets of paper. You are going to use the scale 1 foot: 2 inches. That is, 1 foot in real life will be represented by 2 inches on your paper. How many square inches of paper do you need for the bedroom? Enter just the number in the blank below.
Answer:
(/480/) is the answer I just took the test
Step-by-step explanation:
The number of square inches of papar we need for the bedroom is 480.
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For this case, the scale drawing is converting
1 foot (of real world) : 2 inches (on drawing paper).
Thus, 1 sq. ft area = 2^2 = 4 sq. inch area on paper. (we squared 2, since the square whose sides are 1 ft in real world, will haves sides of 2 inches in drawing, so a side of 2 inches sq. has 4 sq. inch area.)
The area of the floor is 120 sq. ft (some parts are missing in the question statement).
So, as 1 sq. ft : 4 sq. inches on paper,
thus, 120 sq. ft : 120 × 4 = 480 sq. inches area on paper.
Thus, to draw the whole bedroom (which is based on the floor), we need at least 480 sq. inches of paper.
