Answer: $11,870.32
Step-by-step explanation:
Use a compound interest formula for this as it shows what happens when when something increases at a certain rate per period.
= Amount * ( 1 + rate) ^ no. of periods
= 10,368 * ( 1 + 7%) ²
= 10,368 * 1.1449
= $11,870.3232
= $11,870.32
A camera has a listed price of $833.99 before tax. If the sales tax rate is 8.5%, find the total cost of the camera with sales
tax included.
Round your answer to the nearest cent, as necessary.
Answer:
904.88
Step-by-step explanation:
8.5% of 833.99 is 70.88915
70.88915 + 833.99 = 904.87915
904.87915 rounded to the closest cent is 904.88

Find the domain for the rational function f(x) = x-5/2x-3
Answer:
the domain of f(x) is set of all real numbers except 3/2
Step-by-step explanation:
Since the denominator cannot equal 0, 2x - 3 ≠ 0
2x ≠ 3
x ≠ 3/2
Any real number can replace x in the numerator.
So, the domain of f(x) is all real numbers except 3/2
The domain of the given function is required.
The domain is (-∞,3/2),(3/2,∞)
Domain of a functionThe given function is [tex]f(x)=\dfrac{x-5}{2x-3}[/tex]
The domain of a function are the values of x for which the given function is defined.
The function is undefined when [tex]x=\dfrac{3}{2}[/tex]
[tex]f(3/2)=\dfrac{\dfrac{3}{2}-5}{2\times \dfrac{3}{2}-3}=\infty[/tex]
So, [tex]x\neq \dfrac{3}{2}[/tex]
The domain is [tex]\left(-\infty,\dfrac{3}{2}\right),\left(\dfrac{3}{2},\infty\right)[/tex]

How many solutions exist for the given equation?
1/2(x + 12) = 4x-1
zero
one
two
infinitely many
Answer:
one
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] (x + 12) = 4x - 1 ( multiply through by 2 to clear the fraction )
x + 12 = 8x - 2 ( subtract x from both sides )
12 = 7x - 2 ( add 2 to both sides )
14 = 7x ( divide both sides by 7 )
2 = x

A new pain reliever is advertised as being 97%
effective. To 3 decimal places, what is the
probability that the pain reliever will be effective
in 12 independent trials?
A. 0.116
B. 0.694
C. 0.970

A bridge being designed will cross the river at a right angle. The equation of the left bank of the river is j = 2x+8. The center of the bridge will pass through (0,2). What is the equation of the line representing the bridge?
This is the same as y = -0.5x+2
==========================================================
Explanation:
Refer to the diagram below.
The blue line is the graph of y = 2x+8, which is the left bank of the river.
For now, ignore the y = (-1/2)x+2 in the diagram and pretend we don't know that just yet. The red line is the bridge and it's some linear equation in the form y = mx+b. We're told the bridge is perpendicular to the river, so the bridge must also be perpendicular to the riverbank.
The blue line has slope m = 2. Apply the negative reciprocal to this to end up with -1/2. This is the perpendicular slope, and the slope of the red line. Note how the two slopes (2 and -1/2) multiply to -1. Any two perpendicular lines will have their slopes multiply to -1, as long as neither line is vertical or horizontal.
Since we want the bridge to pass through (0,2), this must mean the y intercept is b = 2.
So with m = -1/2 and b = 2, we go from y = mx+b to y = (-1/2)x + 2 which is the equation of the bridge shown in red.
This is the same as y = -0.5x + 2 since -1/2 = -0.5

c) 3 1/47 horas.
d) 4 36/47 horas.
Answer:
b) [tex]2\dfrac{26}{47}\ \text{horas}[/tex]
Step-by-step explanation:
Tiempo necesario para completar el trabajo en primera persona = 6 horas

Tiempo necesario para completar el trabajo por segunda persona = 8 horas
Trabajo hecho en 1 hora = [tex]\dfrac{1}{8}[/tex]

Five less than the product of 6 and a number equals 7
Answer:12
Step-by-step explanation:you start at the beginning like 6 times 1 is 6 but 6 times two is 12 minus 5 equals 7
The statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the statement -
"Five less than the product of 6 and a number equals 7"
We can model this statement as an expression as follows. Let the number be {x}. Then, we can write that -
6x - 5 = 7
Therefore, the statement - "Five less than the product of 6 and a number equals 7" can be modelled as (6x - 5 = 7).

answer this plzz bc im confused i dont know what to do
Answer:
(2, 3)
Step-by-step explanation:
What is the solution to the system of equations represented by these two lines?
The solution of a system is a point that the lines have. In other words, it is the point where the two lines intersect.
The lines intersect at (2, 3), so the answer is the last option.
There is also a more reliable method of solving. In order for the two lines to be equal, their equations (1.5x = y and y= -0.5x + 4) must be equal.
So,
1.5x = -0.5x + 4
Add 0.5x to both sides.
2x = 4
x = 2.
Now, find how much y must be when x equals two. (You can use either equation to do this)
y = 1.5 * 2
y = 3.
Thus, the coordinates are (2, 3).

Can anyone help me out and summarize this, please: That’s his problem. It’s not your problem. There isn’t a tactful way to deal with somebody who has temper fits and throws a little fit about everything that’s about them. He doesn’t get to decide how you run your family. “I’m sorry. I can’t come. I don’t have the money, and we don’t borrow money. You’ve got to have a little more communication about things than that. Sorry.”
Furious is furious, and such it is. I can’t control other people’s temper fits. I can’t fix that for them. They have to deal with their own self on that. You can’t do it otherwise. It’s that simple.
(I need this for a class soon and if anyone could help it would be appreciated )

Step-by-step explanation:
Answer:
Managing kids can be a challenge. Some days keeping the peace while keeping your cool seems impossible. But whether you're reacting to an occasional temper flare-up or a pattern of outbursts, managing your own anger when things get heated will make it easier to teach kids to do the same.
To help tame a temper, try to be your child's ally — you're both rooting for your child to triumph over the temper that keeps leading to trouble.
While your own patience may be frayed by angry outbursts, opposition, defiance, arguing, and talking back, it's during these episodes that you need your patience most. Of course you feel angry, but what counts is how you handle that.
Reacting to kids' meltdowns with yelling and outbursts of your own will only teach them to do the same (and actually is associated with an increase in children's negative behaviors). But keeping your cool and calmly working through a frustrating situation lets you show — and teach — appropriate ways to handle anger and frustration.
Let's say you hear your kids fighting over a toy in the other room. You have ignored it, hoping that they would work it out themselves. But the arguing turns into screaming and soon you hear doors slamming, the thump of hitting, and crying. You decide to get involved before someone gets really hurt.
By the time you arrive at the scene of the fight, you may be at the end of your own rope. After all, the sound of screaming is upsetting, and you may be frustrated that your kids aren't sharing or trying to get along. (And you know that this toy they're fighting over is going to be lost, broken, or ignored before long anyway!)
So what's the best way for you to react? With your own self-control intact. Teaching by example is your most powerful tool. Speak calmly, clearly, and firmly — not with anger, blame, harsh criticisms, threats, or putdowns.
Of course, that's easier said than done. But remember that you're trying to teach your kids how to handle anger. If you yell or threaten, you'll model and ingrain the exact kinds of behavior you want to discourage. Your kids will see that you're so angry and unable to control your own temper that you can't help but scream — and that won't help them learn not to scream.
