36 - 40. In order to save for her high school graduation, Marie decided to save P200 pesos at the end of each month. If the
bank pays 0.250% compounded monthly, how much will her money be at the end of years?​

Answers

Answer:

200.4 at 0.25%

Step-by-step explanation:

Given data

P= P200

r= 0.25%

t= 1 year

n= 12

A= P(1+ r/n)^nt

substitute

A= 200(1+ 0.0025/12)^12*1

A= 200(1+ 0.00020833333)^12

A= 200(1.0002)^12

A= 200* 1.002

A= 200.4

Hence the amount is 200.4 at 0.25%

Cost of five lemons is $2.
What is the cost per lemon?
Answer: $
per lemon
Part B
At this rate, what is the cost of 9 lemons?

Answers

Answer:

Part a: $0.40 per lemon,  Part b: $3.60

Step-by-step explanation:

Because the cost of five lemons is $2, it would be: 5 lemon = $2

$2/5 lemons = $x/1 lemon

so divide by 5 on the numerator and denominator. 2 divided by 5 = 0.4

So part a: 40 cents or $0.40 per lemon!

Part B:

cost of 1 lemon compared to 9 lemons:

$0.40/1 = x/9

Multiply both numerator and denominator by 9

So, it costs $3.60 for 9 lemons.

Help!! Find the area of the triangle.

Answers

Answer:

Area = 60.0 units²

Step-by-step explanation:

First, let's find the height of the triangle using Pythagorean Theorem:

Height = √(11² - 8²)

= √57

Height = 7.5 (nearest tenth)

✔️Find the area:

Area = ½*base*height

Base = 2*8 = 16

Height = 7.5

Plug in the values

Area = ½*16*7.5

Area = 60.0 units² (nearest tenth)

a. Explain in words what is done to the input value (20) to produce the output value (y).
b. Write the rule you described in part (a) with algebraic symbols.

Answers

Answer:

(a) Rule: Multiply the input (x) by 2 and add 5 to the result of the product

(b) [tex]y =2x +5[/tex]

Step-by-step explanation:

Given

The attached table

Solving (a): The rule of the table in words

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Using:

[tex](x_1,y_1) = (2,9)[/tex]

[tex](x_1,y_1) = (10,25)[/tex]

So, we have:

[tex]m = \frac{25 - 9}{10 - 2}[/tex]

[tex]m = \frac{16}{8}[/tex]

[tex]m=2[/tex]

The equation is calculated using:

[tex]y - y_1 =m(x - x_1)[/tex]

Using:

[tex](x_1,y_1) = (6,17)[/tex]

We have:

[tex]y - 17 =2(x - 6)[/tex]

[tex]y - 17 =2x - 12[/tex]

Make y the subject

[tex]y =2x - 12+17[/tex]

[tex]y =2x +5[/tex]

Hence, the rule is:

Multiply the input (x) by 2 and add 5 to the result of the product

(b): The rule, in algebra

As solved in (a), the rule is:

[tex]y =2x +5[/tex]

find the image of (-4,2) obtained by translating 3 units up, followed by a reflexion over the x axis

Answers

Answer:

(-4,-5)

Step-by-step explanation:

1. Image is the points after the transformation

2. Pre-Image is the original points

3. our x value is left to right and our y value is up and down (x,y)

4. Our points are (-4,2)

5. They first want us to translate three units up, so we add to our y value (y is up and down)

6. 2+3 = 5

7. Our new points are (-4,5)

6. Now we are asked to reflect over the x axis. Remember their are a lot of rules concerning reflections. For a reflection across x-axis our equation is this : (x,y) → (x,-y)

7. (-4,5) → (-4,-5)

8. (-4,-5) is our answer

In a GP, the sixth term is eight times the tenth term. The sum of the seventh and the eighth term is 192. Find the common ratio and the first term?

Answers

Let a(n) denote the n-th term in the GP. We're given

a(6) = 8a(10)

a(7) + a(8) = 192

In a geometric progression, consecutive terms are scaled up or down by a fixed ratio r such that

a(n) = r a(n - 1)

By substitution, we get

a(n) = r (r a(n - 2)) = r ² a(n - 2)

and we can continue the pattern down to the first term,

a(n) = r a(n - 1) = r ² a(n - 2) = r ³ a(n - 3) = … = rⁿ ⁻¹ a(1)

So we can rewrite the first two equations in terms of the first term of the GP a(1) and the common ratio r :

ra(1) = 8ra(1)

ra(1) + ra(1) = 192

Solve the first equation for r :

ra(1) = 8ra(1)   →   1 = 8r ⁴   →   r = 1/∜8 ≈ 0.5946

Solve the second equation for a(1) :

ra(1) + ra(1) = ra(1) (1 + r ) = 1/(16√2) a(1) (1 + 1/∜8) = 192

→   a(1) = 6144 ∜2 / (1 + ∜8) ≈ 2724.48

Use the ratio table to solve the percent problem.

What are trigonometric ratios in terms of a right-angle triangle?

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, An observer (O) spots a bird flying at a 42° angle from a line drawn horizontally to its nest.

The hypotenuse distance which is from the observer's eye to the bird's nest is 17000ft and we need the horizontal distance or the distance of the adjacent.

∴ , cos = adjecen/hypotenuse.

cos42° = adjacent/17000.

adjacent = 17000×cos42°.

adjacent = 17000×0.743.

adjacent = 12631 feet.

Step-by-step explanation:

When surveys incorporates a large number of people of a whole population, coupled with the fact that subjects of the survey or research are not compelled to make a choice or air their opinion. In the scenario above, opinion about the new policy is to be expressed by a large audience whereby there is a high tendency that some will no interest in the news nor its content. Leaving only those audience who are more interested and likely the most affected by the policy to respond. This way there will be no distinction between those who disagree and those who fail to respond. It would be more advisable to employ a sample audience who are interested and woykd give a verdict on the policy.
