Questão 11 - Um investidor aplicou
a quantia de R$ 500,00 em um fundo
de investimento que opera no regime
de juros simples. Após 6 meses o
investidor verificou que o montante
era de R$ 560,00. Qual a taxa de
juros desse fundo de investimento?

Answers

Answer 1

Answer:

A taxa de juros desse fundo de investimento é de 24% ao ano.

Step-by-step explanation:

Esta é uma questão que envolve juros simples.

A quantidade de juros acumulados depois de t anos é dado por:

[tex]J = P*r*t[/tex]

Em que P é o investimento inicial, r é a taxa de juros, é t é o tempo, em anos.

O montante é dado por:

[tex]M = J + P[/tex]

Um investidor aplicou a quantia de R$ 500,00.

Isso significa que [tex]P = 500[/tex]

Juros acumulados:

Montante era de R$ 560,00, o que significa que [tex]M = 560[/tex]

Então, a quantidade de juros acumulados é dada por:

[tex]M = J + P[/tex]

[tex]J = M - P = 560 - 500 = 60[/tex]

Taxa de Juros:

6 meses é meio ano, o que implica que [tex]t = 0.5[/tex]

Então

[tex]J = P*r*t[/tex]

[tex]60 = 500*r*0.5[/tex]

[tex]250r = 60[/tex]

[tex]r = \frac{60}{250}[/tex]

[tex]r = 0.24[/tex]

A taxa de juros desse fundo de investimento é de 24% ao ano.

Tell the slope and y-intercept of the graph.

Answers

To find the slope, you can use the formula: [tex]\frac{rise}{run}[/tex]. Start at where the graph intersects at the y-axis, which is -4. So, it rises up 2 units and goes left 3 units, which makes the slope [tex]\frac{2}{3}[/tex].

To find the y-intercept, you would start at where the graph intersects at the y-axis, which is -4 and this would be the y-intercept.

To find the equation, you can use the formula: y = mx + b. m is slope and b is the y-intercept. Plug the slope and y-intercept you found earlier. Thus, your final answer should be: [tex]y = \frac{2}{3}x-4[/tex]

Step-by-step explanation:

A movie theater has been charging $10.00 per person and selling about 500 tickets on a typical weeknight. After surveying their customers, the theater management estimates that for every 50 cents that they lower the price, the number of moviegoers will increase by 50 per night. Find the demand function. (Let x represent the number of tickets sold and p represent the price.)

Answers

Answer:

[tex]p(x) = -0.01x + 15[/tex]

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

[tex](x_1,p_1) = (500,10)[/tex]

A reduction of 50c gives an increment of 50 tickets.

This gives:

[tex](x_2,p_2) = (500+50,10-0,5)[/tex] ---- [tex]50c = \$0.5[/tex]

[tex](x_2,p_2) = (550,9.5)[/tex]

Required

Determine the demand function

First, calculate the slope:

[tex]m = \frac{p_2 - p_1}{x_2 - x_1}[/tex]

[tex]m = \frac{9.5 - 10}{550-500}[/tex]

[tex]m = \frac{-0.5}{50}[/tex]

[tex]m = -0.01[/tex]

So, the equation is:

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

[tex]p = -0.01(x - 500) +10[/tex]

[tex]p = -0.01x + 5 +10[/tex]

[tex]p = -0.01x + 15[/tex]

Hence, the function is:

[tex]p(x) = -0.01x + 15[/tex]

Brian buys 5 cookies and 1 bottle of water. The total cost is $8.75. If the bottle of water costs $1.25, which equation can be used to determine the cost of 1 cookie?

Answers

You have to subtract $1.25 from $8.75 to get $7.50. Since he bought 5 cookies, you need to divide $7.50/5 to get $1.50. So, the cost of each cookie is $1.50

Which statement about the ordered pair (-6,8) is true?

Answers

Answer:

a

Step-by-step explanation:

solve for y in one equation

2x + y = -4

y = -4 - 2x

plug y into the other equation

5x + 3y = -6

5x + 3(-4 - 2x) = -6

5x -12 -6x = -6

-x - 12 = -6

-x = 6

x = -6

plug x into the equation to find y

y = -4 - 2x

y = -4 - 2(-6)

y = 8

ordered pair: (-6,8)

J = 6/5

Step-by-step explanation:

8−6j=9j−10

Step 1: Simplify both sides of the equation.

8−6j=9j−10

8+−6j=9j+−10

−6j+8=9j−10

Step 2: Subtract 9j from both sides.

−6j+8−9j=9j−10−9j

−15j+8=−10

Step 3: Subtract 8 from both sides.

−15j+8−8=−10−8

−15j=−18

Step 4: Divide both sides by -15.

−[tex]\frac{-15j}{-15}[/tex] = [tex]\frac{-18}{-15}[/tex]

Answer:

j = 1.2

Step-by-step explanation:

8 - 6j = 9j - 10​

We can subtract 8 from each side

8 - 6j = 9j - 10​ - 8

Simplify

-6j = 9j - 18

Subtract 9j from both sides

-6j - 9j = 9j - 18 - 9j

Simplify

-15j = -18

Divide by -15 from both sides

[tex]\frac{-15j}{-15}=\frac{-18}{-15}[/tex]

Solve

j = 1.2

If one pair of supplementary angles is a right angle, the other angle must also be a right angle true or false?

Answers

Answer: True

Step-by-step explanation:

A supplementary angle refers to the angles that has a sum of 180° when they're added together.

We should note that a right angle equals to 90°, therefore the other angle in the supplementary angle will be:

= 180° - 90°

= 90°

Since a right angle equals 90°, then the other angle must be a right angle.

Therefore, the answer is TRUE.
