The given expression is
[tex]\sqrt{n^5}\sqrt[3]{n^4}[/tex]To simplify, we first need to write them in exponent form
[tex]n^{\frac{5}{2}}\cdot n^{\frac{4}{3}}[/tex]Now, we can add the exponents
[tex]\begin{gathered} n^{\frac{5}{2}}\cdot n^{\frac{4}{3}}=n^{\frac{5}{2}+\frac{4}{3}}=n^{\frac{23}{6}} \\ \\ Because \\ \frac{5}{2}+\frac{4}{3}=\frac{5(3)+2(4)}{2(3)}=\frac{15+8}{6}=\frac{23}{6} \end{gathered}[/tex]Finally, we can write the expression in radical form
[tex]n^{\frac{23}{6}}=\sqrt[6]{n^{23}}[/tex]Therefore, the answer is

Determine the measures of the unknown angle.
Answers
To find the measure of the unknown angle we can use the triangle sum theorem that states that the sum of the measures of the interior angle of a triangle is 180°. We know the measure of two of the interior angles of the triangle that are 50° and 88°, and we can use this information to find the unknown one:
[tex]\begin{gathered} 50+88+\measuredangle3=180 \\ 138+\measuredangle3=180 \\ \measuredangle3=180-138 \\ \measuredangle3=42 \end{gathered}[/tex]The correct answer is C. 42°.
Given is a parallelogram ABCD. Verify each measure is correct. AE = 10EC = 10 DE = 10EB = 10
Answers
AE = 10 and EC = 10
1) Let's find out the measure of each section of those diagonals. Since in a parallelogram their diagonals are bisected. So we can write:
2y = y+5 Subtract y from both sides
2y -y = 5
y= 5
x+1 = 3x -13
x-3x = -13 -1
-2x =-14
2x = 14
x = 7
2) As we now know the measure of each half of those diagonals we can write:
AE = 2y
AE = 2(5)
AE = 10
EC = y+5,
EC =10
DE = x +1
DE = 8
EB = 3(7) -13 = 8
3) Hence, the correct measures are AE = 10 and EC = 10

to find if it is proportional all the data must fulfill the constant of proportionality.

Answers
Given the experimental results of spinning the spinner:
Yellow: 212
Red: 144
Blue: 144
The sum of times = 500
a) from Martina's results, compute the experimental probability of landing on red.
So, the answer will be probability = 144/500 = 0.288
b) assuming that the spinner is fair, compute the theoretical probability of landing on red.
As shown: the spinner has 10 equally sized slices.
The number of red slices = 3
So, the probability of red = 3/10 = 0.3
c) assuming that the spinner is fair, choose the statement below that is true.
The true statement will be:
1. the larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability.

Answers
Answer:
smaller x-value: (-4, 18)
larger x-value: (3, 11)
Step-by-step explanation:
Solving for x:
y = x^2 + 2
x + y = 14 ---> y = 14 - x
14 - x = x^2 + 2
0 = x^2 + x - 12
0 = (x + 4)(x - 3)
x = -4 or 3
Solving for y:
If x = -4
y = 14 + 4
y = 18
if x = 3
y = 14 - 3
y = 11
Answer:
[tex](x,y)=\left(\; \boxed{-4,18} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]
[tex](x,y)=\left(\; \boxed{3,11} \; \right)\quad \textsf{(larger $x$-value)}[/tex]
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}\phantom{bbbb}y=x^2+2\\x+y=14\end{cases}[/tex]
To solve by the method of substitution, rearrange the second equation to make y the subject:
[tex]\implies y=14-x[/tex]
Substitute the found expression for y into the first equation and rearrange so that the equation equals zero:
[tex]\begin{aligned}y=14-x \implies 14-x&=x^2+2\\x^2+2&=14-x\\x^2+2+x&=14\\x^2+x-12&=0\end{aligned}[/tex]
Factor the quadratic:
[tex]\begin{aligned}x^2+x-12&=0\\x^2+4x-3x-12&=0\\x(x+4)-3(x+4)&=0\\(x-3)(x+4)&=0\end{aligned}[/tex]
Apply the zero-product property and solve for x:
[tex]\implies x-3=0 \implies x=3[/tex]
[tex]\implies x+4=0 \implies x=-4[/tex]
Substitute the found values of x into the second equation and solve for y:
[tex]\begin{aligned}x=3 \implies 3+y&=14\\y&=14-3\\y&=11\end{aligned}[/tex]
[tex]\begin{aligned}x=-4 \implies -4+y&=14\\y&=14+4\\y&=18\end{aligned}[/tex]
Therefore, the solutions are:
[tex](x,y)=\left(\; \boxed{-4,18} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]
[tex](x,y)=\left(\; \boxed{3,11} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

To draw each line, we need to know 2 points
So, we will substitute with 2 values of x and calculate the corresponding value of y
For the first equation: y = 2x - 2
[tex]\begin{gathered} x=0\rightarrow y=2\cdot0-2=-2 \\ x=2\rightarrow y\rightarrow=2\cdot2-2=2 \end{gathered}[/tex]So, the line passes through the points ( 0, -2 ) and ( 2, 2)
For the second line: y = -x + 7
[tex]\begin{gathered} x=0\rightarrow y=0+7=7 \\ x=2\rightarrow y=-2+7=5 \end{gathered}[/tex]so, the line passes through the points ( 0, 7) and ( 2, 5)

Answers
$23,775.00 will be the total amount in the account after 18 years, Formula of simple interest = A = P(1 + rt).
What is simple interest?
The straightforward interest formula makes figuring out how much interest will be applied to a loan quick and simple. Multiply the principle, this same number of days between payments, as well as the daily interest rate to determine simple interest.
Although this method of calculation is used in some mortgages, this type of interest is typically associated with auto loans as well as short-term loans.
Simple interest is calculated by multiplying the principle by the daily interest rate and number of days among payments.Simple interest rewards borrowers for making on-time or early monthly payments on their loans.Auto loans as well as short-term personal loans are two common uses for simple interest loans.A represents the total amount of accrued interest and principal.
P is the principal amount.
The interest rate is I.
The annual percentage real interest rate, abbreviated as r, is 1/10.
R is the interest rate in annual percentage terms; R = r * 100 t is the time period in months or years.
In light of the query
P=$1500
r=3.25%
=0.0325
t=18 years
simple interest = 1500(1+ 0.0325 x 18)
=$(1500+877.5)
=$ 23,775
Thus the simple interest is $23,775

A supermarket is holding a raffle for a new wrist watch. Out of the 500 tickets sold, David buys ticketsnumbered 5, 6, 7, and 8. What are the odds in favor of David's winning the raffle?O 1:500O 500:1O 1:124O124:1

Explanation:
Total tickets = 500
Tickets number bought by David = 5, 6, 7 and 8
Number of tickets bought by David = 4
Remaining ticket = 500 - Number of tickets bought by David
Remaining ticket = 500 - 4
Remaining ticket = 496

The number line shows numbers graded into three parts each such that each point between numbers represent 0.33 units.
This means the red line moving towards the left is a negative because it falls to the left of point 0, where the division between positive and negative numbers take place.

Given:
The first-three digits to be 1, 8, 0 out of seven-digit telephone numbers.
Desired outcome:
Total number of possible different telephone numbers

[tex]P=1-\frac{2}{5}=\frac{3}{5}[/tex]Then, we will calculate the probability of failing the 4 shots. So, we need to multiply 3/5 by itself 4 times.
[tex]P(\text{fail all times) = }\frac{3}{5}\times\frac{3}{5}\times\frac{3}{5}\times\frac{3}{5}=0.1296[/tex]Finally, the probability of her shooting in at least 1 if the complement of the probability to fail all times, so, the answer is:
