Which of the following is the graph of y=-4√x
Answer:
Please see the attachment for graph.
Step-by-step explanation:
We are a given a equation and need to graph it.
It is square root function. We make table of x and y and then plot the points on graph and join the points.
We will take some random values of x and then find the value of y corresponding to the value of x.
For x=1, Put x=1 into equation
[tex]y=-4\sqrt{1}=-4[/tex]
For x=4, Put x=4 into equation
[tex]y=-4\sqrt{4}=-8[/tex]
For x=9, Put x=9 into equation
[tex]y=-4\sqrt{9}=-12[/tex]
Table of x and y
x y
1 -4
4 -8
9 -12
Now we plot the points on graph and join the points.

You flip a coin 10 times. Knowing that the event satisfies the requirements for a binomial distribution, find the probability that exactly 7 of the outcomes are heads.
Answer:
0.1172
Step-by-step explanation:
The formula for the probability in a binomial distribution (n trials, r successes) is
[tex]\binom{n}{r}(p)^r(1-p)^{n-r}[/tex] where p is the probability of success.
For flipping a coin, the probability of success, p, is 0.5.
The number of trials, n, is 10. The number of successes, r, is 7. This gives us
[tex]\binom{10}{7}(0.5)^7(1-0.5)^{10-7}\\\\\binom{10}{7}(0.5)^7(0.5)^3=0.1171875 \approx 0.1172[/tex]

If 30 cents out of every 1 dollar goes to taxes and the rest is net income, what's the ratio of taxes to net income? A. 3 : 10 B. 30 : 1 C. 3 : 7 D. 30 : 7
If 30 cents out of every 1 dollar go to taxes, the remaining 70 cents is the net income. Therefore, the ratio of taxes to net income is 3:7.
Explanation:The question asks for the ratio of taxes to net income if 30 cents out of every 1 dollar go to taxes. This question is asking for a mathematical comparison between the amount of money that goes to taxes and the remaining amount of money, which is the net income.
If 30 cents go to taxes out of 1 dollar, that means 70 cents (or $0.70) is the net income because 1 dollar minus 30 cents equals 70 cents. To arrive at the ratio, we compare the amount that goes into taxes to the net income. This would be 0.30 (taxes) to 0.70 (net income).
When we express this as a ratio in simplest form, we do not usually use decimals. Instead, we can convert the decimal into a whole number. Think of the 0.30 and the 0.70 as 30 and 70. The greatest common divisor of 30 and 70 is 10. If we divide both numbers by 10, we get 3 and 7. So, the ratio of taxes to net income is 3:7. Thus, the correct option is C. 3 : 7.

Find the slope of the line that contains the points named. A(3, 2), B(7, 8)
Answer:
3/2
Step-by-step explanation:
To find the slope of the line that contains the points A(3, 2) and B(7, 8), we can use the formula for slope:
slope = (change in y) / (change in x)
Let's calculate the values:
Change in y = 8 - 2 = 6
Change in x = 7 - 3 = 4
Now, we can find the slope:
slope = 6 / 4 = 3/2
Therefore, the slope of the line that contains the points A(3, 2) and B(7, 8) is 3/2.
The tax revenue that a small city receives increases by 3.5% per year. in 1990, the city received $250,000 in tax revenue. Determine the tax revenue in 1995 and in 2006.
To find the tax revenue in 1995 and 2006 for a city with an annual increase of 3.5%, we use the formula for exponential growth. The revenue in 1995 is calculated to be $296,923, and for 2006, it is calculated to be $438,995.
Explanation:The tax revenue that a small city receives increases by 3.5% per year. To calculate the tax revenue for the years 1995 and 2006, we can use the formula for exponential growth: Final Amount = Initial Amount * (1 + Growth Rate)Number of Years.
For 1995, which is 5 years after 1990, the calculation would be:
Revenue in 1995 = $250,000 * (1 + 0.035)5
Revenue in 1995 = $250,000 * (1.035)5
Revenue in 1995 = $250,000 * 1.18769
Revenue in 1995 = $296,923
Similarly, for 2006, which is 16 years after 1990, the calculation would be:
Revenue in 2006 = $250,000 * (1 + 0.035)16
Revenue in 2006 = $250,000 * (1.035)16
Revenue in 2006 = $250,000 * 1.75598
Revenue in 2006 = $438,995

The Symmetric Property of Congruence allows you to say that if ∠LMN ≅ ∠NSP, then ∠NSP ≅ _____.
The Symmetric Property of Congruence states that If angle A is equivalent to angle B then the angle B will also be equivalent to angle A .
In the problem it is given that ∠LMN ≅ ∠NSP
So, as per the Symmetric Property of Congruence ∠NSP ≅ ∠LMP
The Symmetric Property of Congruence allows you to say that if ∠LMN ≅ ∠NSP, then ∠NSP ≅ ∠LMN.
Hope this helps..!!
Thank you :)
The correct completion of the statement using the Symmetric Property of Congruence is: If [tex]\( \angle LMN \cong \angle NSP \)[/tex], then [tex]\( \angle NSP \cong \angle LMN \)[/tex].
The Symmetric Property of Congruence states that if two angles are congruent, then the second angle is also congruent to the first. In other words, the order in which the angles are listed does not affect the congruence. Therefore, if [tex]\( \angle LMN \)[/tex] is congruent to [tex]\( \angle NSP \)[/tex], it follows that[tex]\( \angle NSP \)[/tex] is congruent to [tex]\( \angle LMN \)[/tex]. This property is a fundamental aspect of geometry that allows us to reverse the order of the angles in a congruence statement without changing the meaning of the statement.

The base of a triangle measures (8x + 2) units and the height measures (4x − 5) units.
Part A: What is the expression that represents the area of the triangle? Show your work to receive full credit. (4 points) Hint: Area = 0.5bh
Part B: What are the degree and classification of the expression obtained in Part A? (3 points)
Part C: How does Part A demonstrate the closure property for polynomials? (3 points)
Part A:
As given,
Base of the triangle = 8x + 2 units
Height of the triangle = 4x − 5 units
Formula to find area of a triangle = [tex]\frac{base * height}{2}[/tex]
= 0.5bh
we have been given base and height, so the area becomes,
area = [tex]\frac{(8x+2)(4x-5)}{2}[/tex]
area = 0.5(8x+2)(4x-5)
= 0.5(32x²-32x-10)
= 16x²-16-5
after factoring it, we get
area = (4x-5)(4x+1) units.
Part B:
It is a degree 2 polynomial as the polynomial has one variable that is x, and the largest exponent of that variable is 2.
Part C:
Part A demonstrates the closure property of polynomials because after multiplying two polynomials we get another polynomial.

There is a sales tax of $14 on an item that costs $147before tax. A second item costs$84 before tax. What is the sales tax on the second item?
To calculate the sales tax on the second item, we determined the sales tax rate from the first item and applied it to the second item's cost, resulting in $7.99 sales tax on the second item.
Explanation:To find the sales tax on the second item, we use the information provided about the first item to determine the rate of sales tax and then apply this rate to the second item. If the first item costs $147 with a sales tax of $14, we can find the sales tax rate by dividing the sales tax by the cost of the item before tax:
Sales tax rate = Sales tax / Price before tax
= $14 / $147
= 0.0952 or 9.52%
Once we have the sales tax rate, we can calculate the sales tax on the second item, which costs $84 before tax:
Amount of sales tax = Price × Rate of sales tax
= $84 × 0.0952
= $7.99 (rounded to the nearest cent)
Therefore, the sales tax on the second item is $7.99.

compare the first factor to the value of the product I did A B C but I don't understand D the question ANSWER FAST PLZ
The first factor with the value of the product is compared as below.
What are Factors?Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.
For example, 10 = 2 × 5
So we can say that 2 and 5 are factors of 10.
Here there are 3 products.
(a) [tex]\frac{1}{3}[/tex] × 1
Here the first factor is [tex]\frac{1}{3}[/tex].
And the product of the two factors is [tex]\frac{3}{9}[/tex].
[tex]\frac{3}{9}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{3}{3}[/tex]
Numerator and denominator when take three times gives the product.
(b) First factor is [tex]\frac{2}{3}[/tex] and the product is [tex]\frac{14}{21}[/tex].
[tex]\frac{14}{21}[/tex] = [tex]\frac{2}{3}[/tex] × [tex]\frac{7}{7}[/tex]
Numerator and denominator when multiplied by 7 times gives the [tex]\frac{14}{21}[/tex].
(c) First factor is [tex]\frac{5}{2}[/tex] and the product is [tex]\frac{25}{10}[/tex].
[tex]\frac{25}{10}[/tex] = [tex]\frac{5}{2}[/tex] × [tex]\frac{5}{5}[/tex]
Numerator and denominator when multiplied by 5 gives [tex]\frac{25}{10}[/tex].
Hence the first factor and products are compared.
