Amount of money in the account after 19 years when no deposits or withdrawals are done for the invested amount $3,500 with 3.5% interest rate compounded quarterly is equal to $6,800(nearest hundred dollars).

As given in the question,

Amount  invested by Nathan is principal 'P' = $3,500

Interest rate 'r' = 3.5% compounded quarterly

Number of compounding periods per year for given quarterly 'n'  = 4

Time period 't'= 19 years

Amount of money in the account after 19 years when no deposits or withdrawals are done.

Let 'A' be the amount.

Formula used:

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

Substitute the value in the formula we get,

A = 3500 × [ 1 + (0.035/4) ]⁽⁴⁾⁽¹⁹⁾

   =  3500 × [ 1 + 0.00875]⁽⁴⁾⁽¹⁹⁾

   =  3500 × [ 1.00875]⁷⁶

   = 6,786.06 (approximately)

   = $6800 (nearest hundred dollars)

Therefore, amount of money in the account after 19 years when no deposits or withdrawals are done for the invested amount $3,500 with 3.5% interest rate compounded quarterly is equal to $6,800(nearest hundred dollars).

8 hours the driver worked and 240 miles the truck drove.

Assume that the truck traveled y miles per hour. and that the driver worked x hours per day.

The equations describing the provided issue will be

19x + 1.50 y = 512

y = 30x

y = 19 x + 1.50 y = 30 x + 1.50 y

When we enter the second equation into the first one, we get,

19 x + 1.50 (30 x) = 512

19x+ 45x = 512

64x = 512

x = 8

y = 240

The simplified expression is x² + 2x - 15.

We are given a mathematical expression. The expression has two terms. The first term is (x + 5) and the second  term is (x - 3). The terms are multiplied by each other to obtain the final expression. Let the resulting expression be represented by the variable "E". The expression has been solved below.

E = (x + 5)(x - 3)

We will use the distributive property.

E = x*(x - 3) + 5*(x - 3)

E = x*x - x*3 + 5*x - 5*3

E = x² - 3x + 5x - 15

E = x² + 2x - 15

Hence, the expanded and simplified form of the given expression is x² + 2x - 15.

The measure of all the angles is given below :

angle 1 = angle 2 = angle 3 = angle 4 = angle 5 = 60°

Given, ΔWXY is an equilateral triangle and ΔWZY is an isosceles triangle.

We have to find the measure of all the angles,

As, ΔWXY is an equilateral triangle

so, ∠WXY = ∠XYW = ∠YWX = 60°

Now, let ∠WZY = ∠WYZ = x and ∠ZWY = y

so, on applying angle sum property, we get

2x + y =180°

so, y = 60°

and 2x = 120°

x = 60°

Hence, angle 1 = angle 2 = angle 3 = angle 4 = angle 5 = 60°

The measure of each angle of the triangle are 35°, 35°, 110°.

What is an isosceles triangle?

Let's Base angle =x°

Vertex angle = 5° +3x°

The sum of measure of angles of triangle are supplementary.

i.e., Sum of triangle = 180°

So,

x° + x° + 5° + 3x° =180°

5x° + 5° = 180°

5x° = 175°

x° = 175° /5°

 x = 35°

Base angle = 35°

Vertex angle = 5°+ 3x°

                      = 5° + 3×35°

                      = 5° +105°

Vertex angle = 110°

Yes, the cost y in dollars and the amount of yogurt x are proportional the equation is y = 0.08x.

Given:

At the local dairy farm, kareem buys a 32-oz container of yogurt for $2. 56. Jonah buys a 6-oz container of yogurt for $0. 48.

y varies directly as x :

y = kx

k = constant of proportionality

y = 2.56 and x = 32

y = kx

k = y/x

= 2.56/32

k = 0.08

So, we will put these values of x and y in the given expression:

(2*8-12)+(1/2*8*2-10)

First, we will use multiplication:

(16-12)+(8-10)

Answer:

  domain: [0, (6+√39)/4] ≈ [0, 3.06125]

Step-by-step explanation:

You want the realistic domain of a height function h = -16t² +48t + 3.

The given polynomial is defined for all values of t. Since it represents height above the ground, and after the ball is thrown, only function values in the first quadrant are of interest: h ≥ 0, t ≥ 0.

The height becomes zero at t = (6+√39)/4 ≈ 3.061 seconds after the ball is hit. Hence the realistic domain is [0, (6+√39)/4], the interval in which the ball is above ground.

Additional comment

We can solve this using the "completing the square" method.

  t^2 -3t = 3/16 . . . . . . divide by -16, add 3/16

  (t -3/2)^2 = 3/16 +9/4 . . . . . add 9/4 to complete the square

  t = 3/2 ± √(39/16) = (6 ± √39)/4 . . . . . . take the square root, add 3/2

Only the positive value of the solution is applicable to this problem. That value is ...

  h = 0 at t = (6 +√39)/4 ≈ 3.061249

Answer:

y=3x-13

Step-by-step explanation:

Since the parallel equations have equal slope.

The equation of line parallel to y=3x+7 will be y=3x+k.

(4,-1) lies in the line so it satisfies the equation amd we get the value of k as -13 and finally we substitute the value of k in the eqn and we finally get the equation as 3x-y-13=0 or you can also write it as y=3x-13

The equation that describing how x and y are related is y = 2x + 7

From the given table we have to choose two points

The first point = (1, 9)

The second point = (2, 11)

The slope of the line is the change in y coordinate with respect to the change in x coordinate of the line

The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values in the equation

The slope of the line = (11-9) / 2 - 1

= 2 / 1

= 2

From the table

At x = 0 the value of y = 7

Therefore the y intercept = 7

The slope intercept form is

y = mx + b

Where m is the slope of the line

b is the y intercept

Then,

y = 2x + 7

Hence, the equation that describing how x and y are related is y = 2x + 7
