Answer:
Domain: x <= 4
Step-by-step explanation:
The domain is all the x's on the graph or all the x's that can be used in the equation. see image for graph. The graph exists coming from negative infinity (the left side of the graph) and then stops at the point where x is 4. So x must be less than 4 or equal to 4.
Algebraically, if x is bigger than 4, you get a negative number inside the radical (the square root symbol) and that is not allowed. Again we find that x has to be less than or equal to 4.

A savings account starts with $420. After 6 years of continuously compounding at an interest rate, r, the account has a balance of $1,300. What is the interest rate percentage (do not type % it is already there)? Round answer to the nearest hundredth.
Answers
Answer:
18.83% (nearest hundredth)
Step-by-step explanation:
Continuous Compounding Formula
[tex]\sf A=P(e)^{rt}[/tex]
where:
A = amountP = principal (initial amount)e = mathematical constant ≈ 2.7183r = interest rate (in decimal form)t = time in yearsGiven:
A = $1,300P = $420t = 6 yearsSubstituting given values into the formula:
[tex]\sf \implies 1300=420(e)^{6r}[/tex]
[tex]\sf \implies \dfrac{1300}{420}=e^{6r}[/tex]
[tex]\sf \implies e^{6r}=\dfrac{65}{21}[/tex]
Taking natural logs of both sides:
[tex]\sf \implies \ln e^{6r}=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies 6r\ln e=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies 6r(1)=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies 6r=\ln \dfrac{65}{21}[/tex]
[tex]\sf \implies r=\dfrac16 \ln \dfrac{65}{21}[/tex]
[tex]\sf \implies r=0.1883108054...[/tex]
Therefore, the interest rate is 18.83% (nearest hundredth)

Milk is on sale for 40% off when it is normally $3.75 per gallon. How much will a gallon of milk cost?
The discounted price for milk is $_____(Round to the nearest cent.)
Answers
Answer:
$2.25 is the discounted price for each gallon.
Step-by-step explanation:
So you take 40% and convert it into decimal form, which is 0.4. Then you take $3.75 x 0.4 = 1.5. Then subtract $1.50 from $3.75, and that equals $2.25 each gallon.

what is the opposite of -3.4
Answers
Answer:
3.4
Step-by-step explanation:
The opposite of a number is the same as the additive inverse of the number.
Two numbers are opposites, or additive inverses, if they add to zero.
For a positive or a negative number, just change its sign to find its opposite. For zero, its additive inverse is zero.
The opposite of -3.4 is 3.4.
Answer: 3.4
The opposite of a positive number is a negative number.
The opposite of a negative number is a positive number.
-3.4 is a negative number, so its opposite is a positive number.
Hence, the answer is 3.4

Pls help will give brainliest
Answers
Answer:
slope: 5
y-intercept: 0
Equation: [tex]y=5x[/tex]
Step-by-step explanation:
First, lets find the slope.
Every time we have an increase in [tex]x[/tex], we have an increase in [tex]y[/tex].
To find that change, we will divide the changes in [tex]y[/tex] using two points.
I will be using the points [tex](1,5), (2,10)[/tex]
[tex]\frac{10-5}{2-1}[/tex]
[tex]=5/1[/tex]
[tex]=5[/tex]
Therefore, the slope is 5.
Next, lets find the y-intercept. The y-intercept is where the line goes through the y-axis.
We can go back 1 x-value (since when x = 1, y = 5)
Subtracting our slope (5) from the y-value for 1, we get:
[tex]y=0[/tex]
Therefore, the y-intercept is 0.
Finally, lets find the equation.
Linear equations are in the form [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
Plugging those values in we get: [tex]y=5x+0[/tex]
Which will be simplified down to [tex]y=5x[/tex]

Olga just got a new job, and she is looking to lease a car. Dealer A offers her a $2400 trade-in on her old car, with lease payments of $360 a month. Dealer B offers a trade-in of $2000 with payments of $320 a month. Olga wants to lease the car for only 6 months. Which deal is better for her?
Answers
Answer:
$2000 with payments of $320 a month
Step-by-step explanation:
360 x 6 = 2160
2160 + 2400 = 4560
320 x 6 = 1920
1920 + 2000 = 3920
Answer:
dealer A
Step-by-step explanation:
A: 360×6=2160
2400-2160=240
they save $240
B: 320×6=1920

[tex]\frac{x}{2} =-4[/tex] Subtract 7
[tex]x =-8[/tex] Multiply by reciprocal (2/1)
I hope this helps!
Answer:
X = -8
Step-by-step explanation:
So we will start with subtracting 7 from 3, which is -4.
So now you have x/2 = -4
Now we have to find what divided by 2 equals -4 so, we do 2 x -4, which is -8.
This is how we get our answer, x = -8

It should be noted that the area of a square is simply gotten by multiplying the side by itself. For example, if a side is 4cm, the area will be 4 × 4 = 16cm².
In this case, we are told that each patch has an area of 1 ft. Therefore, the square of the area gotten should not be more than 1 feet. Possible values include:
0.5 × 0.5 = 0.25
