How much simple interest is earned on a principal of $700 after 5 years if the account pays 3% annually?

Answer:

Hypotenuse = 85 cm

Hypotenuse = 89 cm

Hypotenuse = 103.08 cm (Approx.)

Hypotenuse = 54.71 cm (Approx.)

Step-by-step explanation:

Shape 1

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √36² + 77²

Hypotenuse = √1,296 + 5,929

Hypotenuse = √7,225

Hypotenuse = 85 cm

Shape 2

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √39² + 80²

Hypotenuse = √1,521 + 6,400

Hypotenuse = √7,921

Hypotenuse = 89 cm

Shape 3

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √25² + 100²

Hypotenuse = √625 + 10,000

Hypotenuse = √10,625

Hypotenuse = 103.08 cm (Approx.)

Shape 4

Hypotenuse = √Perpendicular² + Base²

Hypotenuse = √17² + 52²

Hypotenuse = √289 + 2,704

Hypotenuse = √2,993

Hypotenuse = 54.71 cm (Approx.)

Answer:

128 seats

Step-by-step explanation:

7/11 = 224 seats

11/11 = ?

(11/11 × 224) ÷ 7/11

224 ÷ 7/11 =

224 × 11/7 = 352 seats(total number of seats)

352 - 224 = 128 seats

Answer:

y= x⁴ -21x²-100

combine x's I think

x⁴= 1x? cuz if it's 1x⁴ that's 1x*1x*1x*1x = 1x

1x * -21x²

-21x * -21x = 441x

+1x = 442x

y= 442x -100

I'm not sure if I did that right

Answer:

it would be 145

Step-by-step explanation:

the two angles make a straight line, 180-35 is 145

Answer: 145

Step-by-step explanation:

supplementary angle rule: on a straight line, all angles add up to 180

180 = 35 + x

180 - 35 = x

145 = x

Answer:

The value of x is 28°

Step-by-step explanation:

Here, In a given figure

4x + 3° ...(1)

2x + 9° ...(2)

Now, we know that the sum of all angle is 180° on a straight line

So,

4x + 3° + 2x + 9° = 180°

6x + 12° = 180°

6x = 180° - 12°

6x = 168°

x = 168° ÷ 6

x = 28°

Thus, The value of x is 28°

4x + 3° + 2x + 9° = 180°

4(28) + 3° + 2(28) + 9° = 180°

112° + 3° + 56° + 9° = 180°

180° = 180°

Hence, L.H.S = R.H.S

Answer:

21134 bacteria

Step-by-step explanation:

The given parametrs can be interpreted as:

[tex]y = 8(2.4)^t[/tex]

Required

Find y when t = 9

Substitute [tex]t = 9[/tex]

So:

Hope this helps.

Given that y₁(x) = x is a solution to the given second-order ODE, assume a second solution of the form

y₂(x) = y₁(x) v(x) = x v(x)

Take the first two derivatives and substitute this solution into the ODE:

y₂ = x v

y₂' = x v' + v

y₂'' = (x v'' + v' ) + v' = x v'' + 2 v'

→   (1 - x ²) y₂'' - 2 x y₂' + 2 y₂ = 0

→   (1 - x ²) (x v'' + 2 v' ) - 2 x (x v' + v) + 2 x v = 0

→   (x - x ³) v'' + (2 - 4 x ²) v' = 0

Next, reduce the order by substituting w(x) = v'(x) and w'(x) = v''(x) :

→   (x - x ³) w' + (2 - 4 x ²) w = 0

and now you have a linear equation in w. Solve for w(x) however you like; I'll just separate variables.

Write w'(x) = dw/dx, then separate variables as

(x - x ³) dw/dx + (2 - 4 x ²) w = 0

(x - x ³) dw/dx = (4x ² - 2) w

dw/w = (4x ² - 2) / (x - x ³) dx

Integrate both sides:

∫ dw/w = (4x ² - 2) / (x - x ³) dx

ln|w| = ∫ (4x ² - 2) / (x - x ³) dx

For the remaining integral, expand the integrand into partial fractions.

x - x ³ = x (1 - x ²) = x (1 - x) (1 + x)

→   (4x ² - 2) / (x - x ³) = a /x + b / (1 - x) + c / (1 + x)

→   4x ² - 2 = a (1 - x ²) + b x (1 + x) + c x (1 - x)

→   4x ² - 2 = (-a + b - c) x ² + (b + c) x + a

→   -a + b - c = 4, b + c = 0, a = -2

→   a = -2, b = 1, c = -1

→   (4x ² - 2) / (x - x ³) = -2/x + 1 / (1 - x) - 1 / (1 + x)

Then

ln|w| = ∫ (-2/x + 1 / (1 - x) - 1 / (1 + x)) dx

ln|w| = -2 ln|x| - ln|1 - x| - ln|1 + x| + C

ln|w| = -ln|x ² (1 - x ²)| + C

exp(ln|w|) = exp(-ln|x ² (1 - x ²)| + C )

w = C / (x ² (1 - x ²))

v' = C / (x ² (1 - x ²))

Solve for v(x) by integrating both sides, expanding the right side into partial fractions again:

x ² (1 - x ²) = x ² (1 - x) (1 + x)

→   1 / (x ² (1 - x ²)) = a / x + b / x ² + c / (1 - x) + d / (1 + x)

→   1 = a x (1 - x ²) + b (1 - x ²) + c x ² (1 + x) + d x ² (1 - x)

→   1 = (-a + c - d) x ³ + (-b + c + d) x ² + a x + b

→   -a + c - d = 0, -b + c + d = 0, a = 0, b = 1

→   a = 0, b = 1, c = 1/2, d = 1/2

→   1 / (x ² (1 - x ²)) = 1/x ² + 1/2 (1 / (1 - x) + 1 / (1 + x))

dv/dx = C (1/x ² + 1/2 (1 / (1 - x) + 1 / (1 + x)))

dv = C (1/x ² + 1/2 (1 / (1 - x) + 1 / (1 + x))) dx

Integrate both sides:

∫ dv = ∫ C (1 / x ² + 1/2 (1 / (1 - x) + 1 / (1 + x))) dx

v = C₁ (-1/x - 1/2 ln|1 - x| + 1/2 ln|1 + x|) + C₂

v = C₁ (1/2 ln|(1 + x) / (1 - x)| - 1/x) + C₂

Solve for y₂(x) by multiplying both sides by x :

y₂ = C₁ (1/2 x ln|(1 + x) / (1 - x)| - 1) + C₂ x

Now, y₁(x) = x, so we can omit the last term from the second solution, giving us

y₂(x) = C (1/2 x ln|(1 + x) / (1 - x)| - 1)

Answer:

The value of g(2.7) is 31.49.

Step-by-step explanation:

Translations of a function:

Suppose that we have a function f(x).

The translation of f(x) a units to the left is given by g(x) = f(x+a).

The translation of f(x) a units to the right is given by g(x) = f(x-a).

The translation of f(x) a units up is given by g(x) = f(x) + a.

The translation of f(x) a units down is given by g(x) = f(x) - a.

Suppose the graph of f(x)=x^2 is translated 3 units right and 1 unit down.

Three units right:

[tex]g(x) = f(x+3) = (x+3)^2[/tex]

One unit down:

[tex]g(x) = f(x+3) - 1 = (x+3)^2 - 1[/tex]

What is the value of g(2.7)?

This is g when [tex]x = 2.7[/tex]. So

[tex]g(2.7) = (2.7+3)^2 - 1 = (5.7)^2 - 1 = 31.49[/tex]

The value of g(2.7) is 31.49.

Step-by-step explanation:

By definition of tangent,

tan(2θ) = sin(2θ) / cos(2θ)

Recall the double angle identities:

sin(2θ) = 2 sin(θ) cos(θ)

cos(2θ) = cos²(θ) - sin²(θ) = 2 cos²(θ) - 1

where the latter equality follows from the Pythagorean identity, cos²(θ) + sin²(θ) = 1. From this identity we can solve for the unknown value of sin(θ):

sin(θ) = ± √(1 - cos²(θ))

and the sign of sin(θ) is determined by the quadrant in which the angle terminates.

We're given that θ belongs to the third quadrant, for which both sin(θ) and cos(θ) are negative. So if cos(θ) = -4/5, we get

sin(θ) = - √(1 - (-4/5)²) = -3/5

Then

tan(2θ) = sin(2θ) / cos(2θ)

tan(2θ) = (2 sin(θ) cos(θ)) / (2 cos²(θ) - 1)

tan(2θ) = (2 (-3/5) (-4/5)) / (2 (-4/5)² - 1)

tan(2θ) = 24/7

Answer:

Look at the answers bolded below

Step-by-step explanation:

To get the reference angle, just subtract 115° from 180°

180 - 115 = 65

So the reference angle is 65°

I'm not sure how many coterminal angles you need, but to get them you could just add or subtract 360°.

For example, a positive coterminal angle could be:

115 + 360 = 475°

a negative coterminal angle could be:

115 - 360  = -245°

Answer:

  b.  255.5 to 499.5

Step-by-step explanation:

The middle 50% is the range between the first and third quartiles. In this group of 9 numbers, the first quartile is the average of numbers 2 and 3 when the numbers are listed from smallest to largest.

  first quartile = (230 +281)/2 = 255.5 . . . . . . matches answer choice B

The third quartile is the average of numbers 7 and 8:

  third quartile = (468 +531)/2 = 499.5 . . . . .  also matches answer choice B

The middle 50% is 255.5 to 499.5.

_____

When I put the numbers in order, I get ...

  198 230 ^ 281 246 376 426 468 ^ 531 540

^ indicates that the quartile here is the average of the adjacent numbers

bold indicates the median (2nd quartile)

Answer:

Henry has $19, Dan has $57, and Melissa has $11

Step-by-step explanation:

Let x represent how much money Henry has

Since Dan has 3 times what Henry has, his amount is 3x

Since Melissa has $8 less than Henry, her amount is x - 8

Create an equation that sets these 3 values equal to 87, then solve for x

(x) + (3x) + (x - 8) = 87

5x - 8 = 87

5x = 95

x = 19

So, Henry has $19

Find how much Dan has by multiplying 19 by 3

19(3)

= 57

Find how much Melissa has by subtracting 8 from 19

19 - 8

= 11

So, Henry has $19, Dan has $57, and Melissa has $11

Answer:

Dan has $261 and Melissa has $79
