Answer:

FV= $10,714.81

Step-by-step explanation:

Giving the following information:

Initial investment= $7,567

Number of periods= 7*4 = 28 quarters

Interest rate= 0.05/4= 0.0125

To calculate the future value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 7,567*(1.0125^28)

FV= $10,714.81

Answer:

The Y intercept is two

Step-by-step explanation:

The y intercept is the point on a graph where the graph crosses the y axis.

Basically, it is the value of y when x is 0 is (x,y)

Looking at the attached graph, our y intercept is (0,2), meaning that the y-intercept is 2.

The answer is: the Y-INTERCEPT is 2

Answer:

70°, ,have a nice day

Answer:

∠BCO = 70°

Step-by-step explanation:

AO = CO = BO because all radii of the same circle are equal.

∠ACO = 20° because it is an isosceles triangle.

∠BCA = 90° because a triangle with it's hypotenuse being the diameter of a circle is a right triangle.

∠BCA - ∠ACO = ∠BCO

90° - 20° = 70°

∠BCO = 70°

Answer:

7 feets

Step-by-step explanation:

Volume of shed, V = 357 feet³

Height of shed, H= 8 1/2 fts

Width of shed, W = 6 ft

Using the relation :

Volume = Length * width * height

357 = L * 6 ft * 17/2 feets

357 feets³ = L * 51 feets²

L = 357 feets³ / 51 feets²

Length, L = 7 feets

Complete question :

A swimming pool is the shape of a right rectangular prism. If the pool is 12 3/4 yards long, 5 2/3 yards wide, and 9 yards deep, what is the volume of the swimming pool

Answer:

650 1/4 yd³

Step-by-step explanation:

Volume of a rectangle prism :

V = Length * width * height

V = 12 3/4 * 5 2/3 * 9

V = 51/4 * 17/3 * 9/1

V = (51*17*9) / (4*3*1)

V = 7803 / 12

V = 650 3/12

Volume of swimming pool = 650 1/4 yd³

I'm assuming you have learned basic trigonometry: SOH CAH TOA. In this diagram to find the angle x we are given the opposite side and the hypotenuse, therefore we will use SOH. sinθ = opp/hyp. Plugging in those values we get sinθ = 5/11 -> θ = sin⁻¹ (5/11) = 27.03569179° = 27°

Answer:

4.90m

Step-by-step explanation:

A sector of a circle of diameter 11 cm is formed from an angle of size 51. Find the length of the arc rounded to two decimal places

Length of an arc = 2πr(θ/360)

(θ) = 51°

r = Diameter/2 = 11/2

= 5.5

Length of an arc = 2 × π × 5.5(51/360)

= 4.89565m

Approximately = 4.90m

Answer:

$ 20,189.65

Step-by-step explanation:

Jake's parents want $100,000 at the end of 40 years. They put their money in an account that yields 4% per year compounded continuously. How much money should jakes parents deposit?

From the above question, we are to find the Principal. The formula for Principal compounded continuously =

P = A / e^rt

Where:

A = Amount after time t = $100,000

r = Interest rate = 4%

t = Time in years = 40 years

First, convert R percent to r a decimal

r = R/100

r = 4%/100

r = 0.04 per year,

Then, solve our equation for P

P = A / e^rt

P = 100,000.00 / e ^(0.04×40)

P = $ 20,189.65

Therefore, the amount Jake's parents should invest = $ 20,189.65

Answer:

3.95

Step-by-step explanation:

R = 7.9/2 = 3.95

Answer:

Step-by-step explanation:

rate of change is the slope of the line

plot the data and calculate the slope or simple find the delta cost divided by the delta people

    (cost x - cost y) / (people x - people y)  = rate of change

you can pick any cost as long as you use the coresponding people

    (19.75 - 7.90) / (5 - 2)  = rate of change

    ( 11 .85) / (3)   = rate

     3.95 = rate

try it for different cost and people and see if you get the same rate, it looks linear to me

Answer:

p = 5k - 40

Step-by-step explanation:

Since we're finding the profit (p), it's not the last answer choice because it's finding kids (k).

Because we have to take out from her profit whatever Katie spent, we would have -40.

Because she'd charging $5 per kid, or $5 per k, we would have 5k.

So now we know the profit is whatever she makes, then minus whatever she spent. So:

p = 5k (what she makes) - 40 (what she spent)

p = 5k - 40

Answer:

O p = 40k + 5

Step-by-step explanation:

Katie is raising money to buy  a dog. She starts a  neighborhood babysitting service.

The Volume of pyramid is 19.5 [tex]m^{3}[/tex].

A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apx. Each base edge and apx form a triangle, called a lateral face.

The volume of a pyramid refers to the space enclosed between its faces.

Volume of pyramid = (1/3) (Base area * height of pyramid )

According to the question

Area of the base = 6.8 [tex]m^{2}[/tex]

Height of the pyramid = 8.6 m

now,

using the formula of Volume of pyramid

Volume of pyramid = (1/3) (Base area * height of pyramid )

substituting the values

Volume of pyramid = (1/3) ( 6.8 * 8.6 )

                                 = 19.49 [tex]m^{3}[/tex]

Rounding off to  nearest tenth of a cubic meter

Volume of pyramid = 19.5 [tex]m^{3}[/tex]

Hence, the Volume of pyramid is 19.5 [tex]m^{3}[/tex]

How I was taught all of these problems is in terms of r, x, and y. Where sin = y/r, cos = x/r, tan = y/x, csc = r/y, sec = r/x, cot = x/y. That is how I will designate all of the specific pieces in each problem.

#3

Let's start with sin here. [tex]\frac{2\sqrt{5}}{5} = \frac{2}{\sqrt{5}}[/tex] Therefore, because sin is y/r, r = [tex]\sqrt{5}[/tex] and y = +2. Moving over to cot, which is x/y, x = -1, and y = 2. We know y has to be positive because it is positive in our given value of sin. Now, to find cos, we have to do x/r.

cos = [tex]\frac{-1}{\sqrt{5}} = \frac{-\sqrt{5}}{5}[/tex]

#4

Let's start with secant here. Secant is r/x, where r (the length value/hypotenuse) cannot be negative. So, r = 9 and x = -7. Moving over to tan, x must still equal -7, and y = [tex]4\sqrt{2}[/tex]. Now, to find csc, we have to do r/y.

csc = [tex]\frac{9}{4\sqrt{2}} = \frac{9\sqrt{2}}{8}[/tex]

The pythagorean identities are

sin^2 + cos^2 = 1,

1 + cot^2 = csc^2,

tan^2 + 1 = sec^2.

#5

Let's take a look at the information given here. We know that cos = -3/4, and sin (the y value), must be greater than 0. To find sin, we can use the first pythagorean identity.

sin^2 + (-3/4)^2 = 1

sin^2 + 9/16 = 1

sin^2 = 7/16

sin = [tex]\sqrt{7/16}[/tex] = [tex]\frac{\sqrt{7}}{4}[/tex]

Now to find tan using a pythagorean identity, we'll first need to find sec. sec is the inverse/reciprocal of cos, so therefore sec = -4/3. Now, we can use the third trigonometric identity to find tan, just as we did for sin. And, since we know that our y value is positive, and our x value is negative, tan will be negative.

tan^2 + 1 = (-4/3)^2

tan^2 + 1 = 16/9

tan^2 = 7/9

tan = -[tex]\sqrt{7/9} = \frac{-\sqrt{7}}{3}[/tex]

#6

Let's take a look at the information given here. If we know that csc is negative, then our y value must also be negative (r will never be negative). So, if cot must be positive, then our x value must also be negative (a negative divided by a negative makes a positive). Let's use the second pythagorean identity to solve for cot.

1 + cot^2 = [tex](\frac{-\sqrt{6}}{2})^{2}[/tex]

1 + cot^2 = 6/4

cot^2 = 2/4

cot = [tex]\frac{\sqrt{2}}{2}[/tex]

tan = [tex]\sqrt{2}[/tex]

Next, we can use the third trigonometric identity to solve for sec. Remember that we can get tan from cot, and cos from sec. And, from what we determined in the beginning, sec/cos will be negative.

[tex](\frac{2}{\sqrt{2}})^2[/tex] + 1 = sec^2

4/2 + 1 = sec^2

2 + 1 = sec^2

sec^2 = 3

sec = -[tex]\sqrt{3}[/tex]

cos = [tex]\frac{-\sqrt{3}}{3}[/tex]

Hope this helps!! :)

Answer: x = 1

Step-by-step explanation:

5 ( 2x - 8 ) + 15 = -15 (write the equation)

5 ( 2x - 8 ) = -30 (subtract by 15 on both sides)

2x - 8 = -6 (divide by 5 on both sides)

2x = 2 (add 8 to both sides)

x = 1 (divide by 2 on both sides)

Answer:

[tex]x = 1[/tex]

Step-by-step explanation:

Skills needed: One-Variable Equations, Solving Equations

1) The first thing is to use P.E.M.D.A.S

There are no Parentheses, or Exponents, so we go to multiplication

The quantity we multiply is: [tex]5(2x-8)[/tex]

Using distributive property (which is [tex]a(b+c) = ab+ac[/tex]), you get:

[tex]5(2x-8) = 5(2x) - 5(8) = 10x - 40[/tex]

2) Now, we substitute back in and combine like terms:

[tex]10x-40+15=-15[/tex]

Combine the -40 and 15 ([tex]-40+15=-25[/tex])

Then, you will get: ([tex]10x-25=-15[/tex])

3) Add 25 to both sides, to isolate the variable:

[tex]10x = -15+25[/tex], and then -15+25 is 10, so

[tex]10x = 10[/tex]

4) Divide by 10 on both sides, and get [tex]x = 1[/tex]
