Answers

Answer 1

Answer: y=-7

there’s no slope so there’s no x

it’s just the y intercept which is -7

Answers

Step-by-step explanation:

$\because \: a_n = - 1 + 3(n - 1) \n \n \therefore \: a_(55) = - 1 + 3(55 - 1) \n \n \therefore \: a_(55) = - 1 + 3 * 54 \n \n \therefore \: a_(55) = - 1 + 162\n \n \huge \blue { \boxed{\therefore \: a_(55) = 161}}\n \n$

Hence, the 55th term of the sequence is 161.

The ratio of money in Terry's bank account to Faye's bank account was 3:5.Terry then put £220 in his account and Faye withdrew £300 from her account.
They now had the same amount in their accounts.
How much did they initially have altogether?

Answers

Answer:

£780 and £1300

Step-by-step explanation:

The ratio in their accounts is 3 : 5 = 3x : 5x ( x is a multiplier )

Terry put £220 into his account, then 3x + 220

Faye withdrew £300 from her account then 5x - 300

They now have the same amounts in their accounts, thus

5x - 300 = 3x + 220 ( subtract 3x from both sides )

2x - 300 = 220 ( add 300 to both sides )

2x = 520 ( divide both sides by 2 )

x = 260

Thus initial amount in their accounts

3 × £260 = £780 ← Terry's account

5 × £260 = £1300 ← Faye's account

A company has introduced two new products to the market. The revenue generated by product A was $63,000 in the first year, and the revenue increases by 3.5% every year.The revenue generated by product B was $81,000 in the first year, and the revenue increases by 2.1% every year.

Which function can the company use to determine its total revenue from the two products, R(x), after they have been on the market for x years, and approximately what will be the revenue generated by sales of the products after 6 years?

R(x) = 9,000[7(1.035)x + 9(1.021)x]; $635,580
R(x) = 9,000[7(1.035)x + 9(1.021)x]; $169,200
R(x) = 9,000[9(1.035)x + 7(1.021)x]; $170,936
R(x) = 9,000[9(1.035)x + 7(1.021)x]; $688,050

Answers

For this case we have functions of the form:
y = A (b) ^ x
Where,
A: initial amount
b: growth rate
x: time
Therefore, substituting values we have:
Product A:
y = 63000 (1,035) ^ x
Product B:
y = 81000 (1,021) ^ x
The sum of the products is:
R (x) = 63000 (1,035) ^ x + 81000 (1,021) ^ x
Rewriting:
R (x) = 9000 (7 (1,035) ^ x + 9 (1,021) ^ x)
Evaluating for 6 years:
R (6) = 9000 * (7 * (1,035) ^ 6 + 9 * (1,021) ^ 6)
R (6) = 169200 $
Answer:
The revenue generated by sales of the products after 6 years is:
R (x) = 9,000 [7 (1,035) x + 9 (1,021) x]; $ 169,200

The correct answer is R(x) = 9,000[9(1.035)x + 7(1.021)x]; $170,936

A tree and a one metre vertical stick cast their shadows at a particular time in the day.The shadow lengths are shown in the diagram below (not drawn to scale).B)Find the scale factor for the side lengths of the triangles.

Answers

Answer:

a) Giving Reasons Why the Two Triangles are Similar

Similar triangles have the same shape but can be different sizes. For triangles to be similar, their matching angles must be equal, and their matching sides must have the same proportions.

In this problem, we have two triangles - one made by the tree, its shadow, and the line connecting the top of the tree to the end of the shadow. The other triangle is made the same way using the stick.

The bottom angle where the shadow meets the ground is 14 degrees for both triangles. Also, the vertical angles where the tree and stick meet the ground are both 90-degree right angles. Using those known angles, we can find the remaining top angles in each triangle, which are both 76 degrees (180 - 90 - 14 = 76).

Since the corresponding angles in the tree shadow triangle and the stick shadow triangle are all equal (14, 90, and 76 degrees), the two triangles have the same shape. This means the tree shadow triangle and stick shadow triangle are similar triangles.

b. Find the scale factor for the side lengths of the triangles.

The scale factor between two similar triangles is the ratio of their corresponding sides. In this case, you should use the length of the shadows to calculate the scale factor.

Since the shadow of the stick is 4m long and the shadow of the tree is 8m long, the scale factor from the tree's shadow to the stick's shadow is 4/8 = 0.5, or 1/2.

c. Find the height of the tree.

Given that the triangles are similar, and the scale factor is 1/2, the height of the tree would be twice the height of the stick because the stick's shadow is half the length of the tree's shadow.

So the height of the tree would be 2 * 1m = 2m.

Hope this helps! :)

Which pair of radicals is a pair of like radicals?
(See image) thanks!

Answers

The pair of radicals that is a like pair is $7√(3)$ and $9 √(3)$

Option C is correct

For two radicals to be similar, they must contain the same number in the root operator.

Two like radicals are in the form:

$a√(b)$ and $c √(b)$

Since $a√(b)$ and $c √(b)$ are like terms, arithmetic operations such as addition, subtraction, multiplication, and division can be carried out on them

Considering the options given, only $7√(3)$ and $9 √(3)$ are in the form $a√(b)$ and $c √(b)$ because they have equal value inside the root operator.

Therefore, the pair of radicals that is a like pair is $7√(3)$ and $9 √(3)$

Step-by-step explanation:

The correlation coefficient for poor health and not exercising in a group of people is 0.67. Analyze the following statement: Poor health is caused by not exercising. Is this a reasonable conclusion?

Answers

Options:

Yes; everyone who doesn't exercise is by definition unhealthy.
Yes; the correlation coefficient is above 0.5, so that implies causation.
No; the data doesn't suggest a causation, and many people are healthy who don't exercise.
No; poor health and not exercising are completely unrelated.

The answer is the third option "No; the data doesn't suggest a causation, and many people are healthy who don't exercise." Correlation is two data set that are linked or connected together so in this case it would be a correlation because all of the data is close and connected to each other.

Hope this helps!

No; the data doesn't suggest a causation, and many people are healthy who don't exercise
