Answer:
The answer is f(x) =√x+4. It would be last one.
I needd help pleaseeeee
If f(×)=1/3×^2+5find f(-9)
Answer:
I think this is the answer
[tex]f( - 9) = \frac{1}{3( - 9) {}^{2} } + 5 \\ = \frac{1216}{243} \\ = 5.0041[/tex]

What is the value of x in the equation −x = 3 − 4x + 6?
−9
−3
3
9
Answer:
The answer is 3
Answer:
x = 3
Step-by-step explanation:
-x = 3 - 4x +6
make the -4x positive and then add it to the -x
-x = 3 +6
+4x
3x = 3 +6
then add the 3 +6 together
3x = 3 + 6
9
3x = 9
we want to get X alone so we are going to divide 3 by both sides
3x/3 = 9/3
1x = 3
and if you did not know we usually don't show the "1" if it is in front of a exponent (you just have to remember that there is a one there)
now you have your answer
x = 3

Tricia and Melanie are both saving money for their summer vacations. They both began saving at the same time. Tricia started with $10.25 and adds $5.15 to her savings every month. Melanie did not have a starting amount but adds $9.25 to her savings every month. Which equation could be used to determine how many months, m, it will take before Tricia and Melanie both have saved the same amount of money?
Group of answer choices
10.25m – 5.15 = 9.25m
10.25m + 5.15 = 9.25m
9.25m + 10.25 = 5.15m
5.15m + 10.25 = 9.25m
Answer:
5.15m + 10.25 = 9.25m
Step-by-step explanation:
Tricia's savings can be calculated with her beginning amount, $10.25, plus a rate of $5.15 that is multiplied by the number of months she saves up, m.
Or, 10.25 + 5.15m.
Melanie saves $9.25 for her vacation, times the months that she saves up, m.
Or, 9.25m.
These two equations are equal to each other at a certain value of m, so our equation is-
5.15m + 10.25 = 9.25m
I hope this helps ^^ Good luck mate
A lock has a 3-number code made up of 15 numbers. If none of the numbers are allowed to repeat, how many different ways can you choose three different numbers in order for a unique code?
Answer:2730
Step-by-step explanation:
The number of ways we can choose three different numbers in order for a unique code for this case is 2730
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total of [tex]^mC_k = \dfrac{m!}{k! \times (m-k)!}[/tex] ways.
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
Given that:
The considered lock as a 3 number codeThere are 15 numbers available.None of the number can repeat.In a lock, the order of the way numbers are arranged matters.
Because of no repetition allowed, we can simulate this situation as:
The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.
And we have:
The number of ways we can choose 3 numbers out of 15 numbers with order = [tex]^{15}P_3 = \dfrac{15!}{(15-3)!} = \dfrac{15 \times 14 \times 13 \times 12!}{12!} = 2730[/tex]
Thus, the number of ways we can choose three different numbers in order for a unique code for this case is 2730

A jeweler makes a necklace using a total of 60 shells and shark teeth. The ratio of shells to shark teeth is 5:1. How many of each does she use?
Options are:
X=2, Y=3
X=3, Y=2
X= -2, Y=3
X=4, Y=8
Answer:
x = 4, y = 8
Step-by-step explanation:
If the triangles are congruent by the HL Theorem, it means that the hypotenuse and one leg of the right triangle are congruent to the corresponding one leg and hypotenuse of the other.
Thus;
2x - 5 = y - 5 (Eqn 1) and
y - 3 = x + 1 (Eqn 2)
Thus:
Rewrite equation 1
2x = y - 5 + 5
2x = y
Substitute y = 2x in equation 2.
y - 3 = x + 1 (Eqn 2)
2x - 3 = x + 1
Collect like terms
2x - x = 3 + 1
x = 4
Substitute x = 4 in equation 1
2x - 5 = y - 5 (eqn 1)
2(4) - 5 = y - 5
8 - 5 = y - 5
3 = y - 5
3 + 5 = y
8 = y
y = 8

If you borrow $900 for 4 years at an
annual interest rate of 5%, how
much will you pay altogether?
Answer:
$995.04
Step-by-step explanation:
You pay $20.73 every month. $20.73 x 48 = $995.04
Answer:
i am going to assume that for interest you mean simple interest.
900*5%*4=180
180+900=1080.
if you mean compound interest...
900*(1+5%)^4=1094.0 (1.d.p)
If you save $110 in one month, how much will you save in one year?
There is 12 months in a year so you need to multiply 12 by 110 which is 1320
Your answer is: 1320 saved in one year
Hope this helped :)

Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.
The owner of a football team claims that the average attendance at games is over 642, and he is therefore justified in moving the team to a city with a larger stadium. Assuming that a hypothesis test of the claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
a) There is not sufficient evidence to support the claim that the mean attendance is greater than 642.
b) There is sufficient evidence to support the claim that the mean attendance is less than 642.
c) There is sufficient evidence to support the claim that the mean attendance is greater than 642.
d) There is not sufficient evidence to support the claim that the mean attendance is less than 642.
Answer:
a) There is not sufficient evidence to support the claim that the mean attendance is greater than 642.
Step-by-step explanation:
since in the question it is mentioned that the average attendance at games should be more 642 and according to this he moving the team with a larger stadium. Also the hypothesis conducted and the conclusion would be failure to deny the null hypothesis
So here the conclusion that should be made in non-technical term is that there should be no enough proof in order to support the claim that the mean attendence is more than $642

Step-by-step explanation:
a) Work out the size of angle x.
b) Give reasons for your answer.
Answer:
x = 75°
Step-by-step explanation:
Angle x and the angle measure 105° are same-side exterior angles. Same-side exterior angles are supplementary. Supplementary angles are angles measures that add up to 180°. So 180° - 105° = 75°. x = 75°
Answer:
75
Step-by-step explanation:
180° - 105° = 75°. x = 75°

A boat travels 120 miles with the current down the river in less time than it takes to travel 80 miles against the current up the river. The boat makes the entire trip in 12 hours. The speed of the boat, without the current, remains constant at 20 miles per hour what is the speed of the current.
Answer:
180 miles is answer
cuz it takes 80 miled to travel in 12 hours
Answer:
The speed of the current is 10 mph
Step-by-step explanation:
x= speed of the current
[tex]\frac{80}{20-x} + \frac{120}{20+x} = 12[/tex]
80 (20+x) + 120 (20-x) = 12 (20-x) (20+x)
