9514 1404 393
Answer:
1.0 N
Step-by-step explanation:
When the length increases by the factor 120/80 = 3/2, the force required is multiplied by the inverse of this: 2/3.
The required force is ...
(2/3)(1.5 N) = 1.0 N

what information is necessary to prove that the two triangles are similar by the AA similarity theorem? show your work
Answer:
Step-by-step explanation:
Let us begin with the AA Similarity definition. It states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
This means that we need:
An angle of one triangle that is congruent to an angle of the other triangle.Another angle of one triangle that is congruent to another angle of the other triangle.For this problem, it is unclear that there are more than one angles that are congruent to each other. We see that angle <DEF and <ABC are congruent, but the problem does not give any other angles. In another case, we must find one more to prove similarity by the AA similarity theorem.
The results of a linear regression are shown below.
y = ax + b
a=-1.15785
b = 139.3171772
r= -0.896557832
r2 = 0.8038159461
Which phrase best describes the relationship
between x and y?
1) strong negative correlation
2) strong positive correlation
3) weak negative correlation
4) weak positive correlation
Answer:
2 hopefully this helps you with work
The best describes the relationship between x and y will be;
⇒ Strong negative correlation.
What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The results of a linear regression are shown below,
⇒ y = ax + b
⇒ a = -1.15785
⇒ b = 139.3171772
⇒ r = -0.896557832
⇒ r₂ = 0.8038159461
Now,
With the value of r we have both the information about the sign of the relationship and the strength of this relationship.
⇒ As the value of r is negative, we can conclude that the correlation between x and y is negative.
Also, as the absolute value of r is close to 1, we can conclude that this relationship is strong.
And, The strength can also be seen in the value of r2, which is also close to 1, but this value does not give information about the sign.
Thus, The value of the slope a, being negative, can also tell us that the relation between x and y is a negative correlation.

Answer:
First Blank: Traditional
Second Blank: (the other choice, besides exempt)
Third Blank: Roth
Fourth Blank: Taxes exempt
Step-by-step explanation:
I got 5/5 on the test by reading through the other guys answer.
In a traditional 401(k), it is tax deferred because the income earned isn't taxed until the money is withdrawn.
What is income tax?Income tax is a tax applied on individuals or entities concerning income or profit earned by them.
A 401 k is a qualified tax-advantaged saving retirement plan. Usually, The 401K plans are employer-sponsored. Employee contributions to the 401 k plans are deducted from the payroll before the taxes can be calculated.
This means that the employee contribution is not taxed at the time it's withheld by the employer.
The amounts saved are invested in market securities such as shares and companies bonds. The tax due from the money from the investment is deferred to the time of withdrawal.
The employee are needed to pay taxes on contributions and investments earning every financial year.

In 2071 the monthly salary of the Chief justice of

Rs. 300000 and certain rate on remaining so that the
chief justice paid Rs. 4537 monthly tax. How much
was the tax percentage on remaining? (Ans: 15%)
Answer:
Step-by-step explanation:
There must be an error—or multiple errors—in the question. Rs 300,000 doesn't make sense, because that would mean he was due a tax refund.
Rs 30,000 doesn't work, either, because that would mean he was paying 18% tax, not 15%.
If a 1% tax was levied on the first Rs 25,000, then he would pay Rs 4,287 on on the remaining Rs 28,580, which would work out to 15%.

a baby goraffe is about 6 1/2 feet tall at birth and grows about 1/2 foot per month for its first year. The function h=1/2m+61/2 represents the total height h of a baby giraffe for any number of months m within ita firat year. How much taller is the giraffe at the end of the month 11 than at the end of month 2
Answer: 4 and 1/2 ft (or 4.5 ft) taller.
Step-by-step explanation:
The function h(m) = (1/2)*m + (6 + 1/2) represents the height (on feet) of the giraffe as a function of the number of months, m.
We want to find the difference in the height between month 11 and month 2, then we need to find:
difference = h(11) - h(2)
We can directly calculate this:
difference = [ (1/2)*11 + (6 + 1/2)] - [(1/2)*2 + (6 + 1/2)]
difference = (1/2)*11 - (1/2)*2 = (1/2)*(11 - 2) = (1/2)*(9) = 9/2
And we can write 9 = 9 + 1, then:
difference = 9/2 = (8 + 1)/2 = 8/2 + 1/2 = 4 + 1/2
And this is in feet, then the girrafe is (4 and 1/2) ft taller on month 11 than on month 2.

Which graph represents the parametric equations x = 1 – t2 and y = 2t, where 0 ≤ t ≤ 5?
ANSWER: A
After plotting the above equation on the coordinate plane, we can see the graph of the function.
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
We have two parametric equations:
x = 1 – t² and
y = 2t
t = y/2 and
0 ≤ t² ≤ 5
1 ≤ 1 - t²≤ 4
1 ≤ x≤ 4
Plug the above value in x = 1 – t²
x = 1- (y/2)²
x = 1 - y²/4
4x = 4 - y²
y² = 4(1 - x)
Thus, after plotting the above equation on the coordinate plane, we can see the graph of the function.

Mai, Clare, and Tyler are hiking from a parking lot to the summit of a mountain. They pass a sign that gives distances. 3 • Parking lot: 3/4 mile • Summit: 1 1/2 miles Mai says: "We are one third of the way there." Clare says: "We have to go twice as far as we have already gone." Tyler says: “The total hike is three times as long as what we have already gone." a) Can they all be correct?
Answer:
Yes they can
Step-by-step explanation:
.
Tyler's statements are consistent with the given distances.
To determine if Mai, Clare, and Tyler can all be correct, we need to evaluate the statements they made in relation to the given distances.
Statement 1: Mai says, "We are one third of the way there."
The distance from the parking lot to the summit is 1 1/2 miles. If they are one third of the way there, the distance they have already traveled would be 1/3 * 1 1/2 miles = 1/3 * 3/2 miles = 1/2 mile. However, the given distance from the parking lot is 3/4 mile, which is greater than 1/2 mile. Therefore, Mai's statement cannot be correct.
Statement 2: Clare says, "We have to go twice as far as we have already gone."
If they have already gone a distance of x, then according to Clare's statement, they have to go a distance of 2x. This statement does not contradict the given distances, so it could be true.
Statement 3: Tyler says, "The total hike is three times as long as what we have already gone."
If they have already gone a distance of x, then according to Tyler's statement, the total hike would be 3x. This statement also does not contradict the given distances, so it could be true.
Based on the analysis, only Mai's statement cannot be correct. Clare and Tyler's statements are consistent with the given distances.

The population of a small town is growing at a rate of 5% per year. If the population right now is 22 000, What will the population be 10 years from now?
Answer:
35,836
Step-by-step explanation:
I had this question before and I believe this is correct.
Answer:
the population 35,836 in 10 years.
Step-by-step explanation:
The numbers representing the population in consecutive years create a geometrical sequence with:
a1 = 22,000
and
q = 1 + 0.5 = 1.05
We are asked to find the population after
10 years. This number is the eleventh term in the sequence, so we are looking for:
a11 = a1 ⋅ q^10 = 22, 000 ⋅ (1.05)^10
After substitution of given data we have:
a11 ≈ 35, 836
*Answer:* "After 10 years the population will be 35, 836."
This question is worth 2 points! Allison makes and sells beaded necklaces. She charges a flat fee of $5 per necklace, and $1.50 per bead that she adds. If Jennifer, who wants to purchase a necklace, has $34 to spend, how many beads can she add to her necklace? Explain the process you used to solve, and tell what your answer is.
Answer:
19 beads
Step-by-step explanation:
If Jennifer has 34$ she automatically loses 5$ because that's the fee for the necklace. So, you subtract 34 from 5 and you get 29. After that you divide 29 by 1.50 and you get 19.333333. But, since you can't get 1/3 of a bead Jennifer can only buy 19 beads.
