Use a calculator to approximate cos 43° and round to
four decimal places.

Answer:

Step-by-step explanation:

complementary angles sum to 90°

Let angle 1 =  x

    angle 2 =  3x - 8

  3x - 8 + x = 90

             4x = 98

               x = 24.5°

3(24.5) - 8 = 65.5°

or

90 - 24.5 = 65.5°

Answer:

558

Step-by-step explanation:

The sum of the first n numbers is ½n(n + 1)

which is the left most number in each row number n

so finding the row containing 526

½n(n + 1) > 526

½n² + ½n > 526

n² + n > 1052

n² + n - 1052 > 0

n > (-1 + √(1² - 4(1)(-1052))) / 2(1)

n > 31.938

so 526 is almost to the end of the 32 row.

The end of that row is ½(32(33)) = 528

so 526 resides two spaces to the right of 528

The end of the row below it, row 33, is ½(33)(34) = 561

As each row is one number longer than the previous row, we count back

2 + 1 = 3 numbers from the end to find what is under 526

561 - 3 = 558

Answer:

$16.25

Step-by-step explanation:

First, you have to find 3.25*5 which is 16.25.

16.25 is the percent rate of your total interest over the course of 5 years.

In other words, you have to do 200*0.1625 which is 32.5.

So, your answer is $16.25.

Good luck!

Answer:

34°

Step-by-step explanation:

21x - 1 + 11x +1 + 26x + 6 = 180

58x -1 +1 +6 = 180

58x +6 = 180

58x = 174

x = 3

11 × 3 + 1 = 34

Answer:

18 gallons

Step-by-step explanation:

We'll find out how much of the total container was lost when pouring out by subtracting 2/3 from 1/2.

2/3 = 4/6

1/2 = 3/6

4/6 - 3/6 = 1/6

1/6 of the total amount the container could hold was lost when 3 gallons was poured out. This means that 1/6 of the container equals to 3 gallons. We can then simply multiply 3 by 6 to find the number of gallons of liquid the container can hold.

3 * 6 = 18 gallons

Checking my answer:

18 * 2/3 = 6 * 2 = 12

12 - 3 = 9

1/2 of 18 = 9

This means that our answer is correct.

Answer:

Step-by-step explanation:

Answer:

Let S = Sum after 13 years

So = amount invested

t = time in years

i = annual interest rate = .0325

The S = So(1+i)t = $2,200(1.0325)13 = $3,334.21

After 13 years, the investment will be worth approximately $4365.67. To calculate the future value of the investment after 13 years with annual compounding interest, we can use the formula for compound interest.

Future Value (FV) = Principal (P) * (1 + (Interest Rate (r) / 100))^Time (n)

Where:

P = Principal (initial investment)

r = Annual interest rate (as a decimal)

n = Number of years

Given:

Principal (P) = $2200

Annual interest rate (r) = 6.25% = 6.25/100 = 0.0625 (as a decimal)

Number of years (n) = 13

Now, let's calculate the future value:

FV = $2200 * (1 + 0.0625)^13

FV = $2200 * (1.0625)^13

FV ≈ $2200 * 1.984396861  (rounded to 9 decimal places)

FV ≈ $4365.672097  (rounded to 2 decimal places)

After 13 years, the investment will be worth approximately $4365.67.

Answer:

C. HI my other account:P

Step-by-step explanation:

From the intercept of the line of best-fit, the car’s approximate initial velocity was of 5.7 m/s.

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.

For this problem, the input and the output are defined as follows:

Hence the points are given by:

(2, 13.1), (4, 19.8), (6, 28.1), (8, 34.6).

Using these points and a calculator, the equation is:

v = 3.64s + 5.7

The intercept of 5.7 represents the initial velocity in m/s.
