B

y= kx + 12

y= 1x – 4

С

D

y = 3.2 – 4

Answer:

y = 3x + 12

Step-by-step explanation:

Slope (m) = 24-9/4-(-1)

= 25/5

= 3

Using point (-1 , 9)

y - y1 = m (x - x1)

y - 9 = 3 (x - -1)

y - 9 = 3 (x + 1)

y - 9 = 3x + 3

y = 3x + 3 + 9

y = 3x + 12

the value ax^2 + bx is 5 when x=1, and is equal to 0 when x=1.what are the values of a and b. explain how u arrived at your answer

**Answer: a = 1.25, b = 2.5, c = 1.25**

**Step-by-step explanation:**

Use vertex form and substitute a point into it (1, 5)

5 = a(1 + 1)^2 + 0

5 = a(2)^2 + 0

5 = 4a

a = 5/4

y = 5/4 (x + 1)^2

y = 5/4 (x^2 + 2x + 1)

1.25 x^2 + 2.5x + 5/4

Is there a "c" value otherwise it's not possible

Yes thats right. MORE TRIG :)

**Answer:**

choice 4) x = 7, y = 7sqrt(3)

**Step-by-step explanation:**

sin 30 = x/14

0.5 = x/14

x = 7

sin 60 = y/14

0.8660 = y/14

y = 12.12 or 7sqrt(3)

The radius of a cylindrical construction pipe is 1.5ft. If the pipe is 17ft long

**Answer:**

The volume is 120.11ft^3

**Step-by-step explanation:**

**Given**

[tex]r = 1.5ft[/tex]

[tex]l = 17ft[/tex]

**Required**

Determine the volume

**This is calculated as:**

[tex]V = \pi r^2h[/tex]

**h, in this case represents the length;**

**So, we have:**

[tex]V = 3.14 * 1.5^2 * 17[/tex]

[tex]V = 120.11ft^3[/tex]

PLZZZ HELP ME I DON'T GET THISq

**Answer:**

**Step-by-step explanation:**

To distribute means to multiply everything outside the parenthesis with everything inside the parenthesis, so in this case 7x8 then 7(x) then 7x2 so that is equal to 56 + 7x + 14, so combine the 56+14 so we get 7x + 70. I hope '7' is part of the problem and not the question number

**Answer:**

7x + 70

**Step-by-step explanation:**

As implied in the question, when you use the distributive property you need to distribute the factor outside the parenthesis to the ones inside the parenthesis.

When we look at 7(8+x+2)

You need to multiply all the factors inside the parenthesis by the 7 outside the parenthesis.

to break it down, do

7*8 = 56

7*x = 7x

7*2 = 14

From here, just add 56+14 to get 70 and then write out your answer as 7x + 70.

what number Multiplied by 0.5, Multiplied by 3, Square the number, Add 1 equals 50?

**Answer:**

**Step-by-step explanation:**

first step: 0.5 * x

second step: 3* (0.5x) = 1.5x

third step: (1.5x)^2

fourth step: (1.5x)^2 + 1 = 50

(1.5x)^2 + 1 = 50 Subtract 1 from both sides

(1.5x)^2 = 49 Take the square root of both sides

1.5x = sqrt(49)

1.5x = +/- 7

1.5x = +7

x = 7/1.5

x = 4.67

1.5x = - 7

x = - 7 / 1.5

x = - 4.67

Which is the solution to the inequality

-4x + 6<2x

**Step-by-step explanation:**

-4x+6<2x

add 4x to both sides

-4x+4x+6<2x+4x

0+6<6x

divide both sides by 6

6/6<6/6x

1<x

all values for the solution to the inequality are greater than 1

Hope that helps :)

The formula for compound interest is:

Where:

A = the future value of the investment (including interest)

P = the principal investment amount (the initial deposit amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested for

If Josh invests $500 in a 5-year fixed interest savings bond that pays 5% per annum, how much will his entire investment be worth at the end of the term?

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 500(1 + \frac{0.05}{365})^{365*5}[/tex]

[tex] A = 500(1 + 0.000137)^{1825}[/tex]

[tex] A = 500(1.000137)^{1825}[/tex]

[tex] A = 500*1.2840 [/tex]

Future value, A = $642

o keep the spectators out of the line of flight at an air show, the ushers arranged the show's seats in the shape of an inverted triangle. Kevin, who loves airplanes, arrived very early and was seated in the front row, which contained one seat. The second row contained three seats, and those filled very quickly. The third row contained five seats, which were given to the next five people who came. The next row contained seven seats. This seating pattern continued all the way to the last row, with each row containing two more seats than the previous row. All 20 rows were filled. How many people attended the air sh

**Answer:**

400 people attended the air show.

**Step-by-step explanation:**

**Arithmetic sequence:**

An arithmetic sequence has the following general equation:

[tex]a_n = a_1 + d(n-1)[/tex]

In which [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term and d is the common difference between the terms.

**The sum of the first n terms of an arithmetic sequence is given by:**

[tex]S_n = \frac{n(a_1+a_n)}{2}[/tex]

**In this question:**

First row 1 seat, second 3 seats, 3rd 5 seats and so on.

So we have the following arithmetic sequence:

{1,3,5,7,9,...}

So [tex]a_1 = 1, d = 9 - 7 = 7 - 5 = ... = 2[/tex]

So

[tex]a_n = 1 + 2(n-1)[/tex]

**All 20 rows were filled. How many people attended the air show?**

Sum of the 20 terms of the progression. So

[tex]S_{20} = \frac{20(1+a_{20})}{2} = 10(1+a_{20})[/tex]

The 20th term is:

[tex]a_{20} = 1 + 2(20-1) = 1 + 2*19 = 1 + 38 = 39[/tex]

So

[tex]S_{20} = 10(1+a_{20}) = 10(1 + 39) = 10(40) = 400[/tex]

400 people attended the air show.
