From Monday - Tuesday, Adam earns $122 dollars. If he continues to earn the same amount for the rest of the week, how much will he have at the end?

Answers

Answer:

$437

Step-by-step explanation:

There are 7 days in a week.

Let's stop at the last even number, the 6th day.

Tuesday is four days away from Sunday, so multiply 122 by 3.

[tex]\mathrm{122}[/tex] × [tex]3[/tex] = [tex]366[/tex]

Finally, we are at the 7th day. There is no 8th day in a week, so divide 122 by 2.

[tex]122[/tex] ÷ [tex]2[/tex] [tex]=61[/tex]

Now, let's add 61 to 366. We get $437, and that is our answer.

Hope this helps!

What is the radius of a circle whose equation is (x + 5)2 + (y - 3)2 = 42?
O 2 units
Ο Ο Ο
4 units
8 units
16 units

Answers

Answer:

The radius of the circle is:

[tex]r=4[/tex] units

Step-by-step explanation:

Given the equation

[tex]\left(x\:+\:5\right)^2\:+\:\left(y\:-\:3\right)^2=\:42[/tex]

As we know that

[tex]\left(x\:-\:a\right)^2\:+\:\left(y\:-\:b\right)^2=\:r^2\:[/tex]

is the equation of the circle with a radius 'r', centered at (a, b)

[tex]\mathrm{Rewrite}\:\left(x+5\right)^2+\left(y-3\right)^2=4^2\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}[/tex]

so, the circle properties are:

[tex]\left(x-\left(-5\right)\right)^2+\left(y-3\right)^2=4^2[/tex]

Therefore, the radius of the circle is:

[tex]r=4[/tex] units

How much will you spend on an investment if you want to receive $7,000 at an annual rate of 6% compounded weekly in 4 years?

Answers

Answer:

The investment required is: $5687

Step-by-step explanation:

Future Amount A= $7000

Rate r = 6% =0.06

Time t = 4

Compounded Weekly = n= 52

We need to find Principal Amount P

The formula used is: [tex]A=P(1+\frac{r}{n})^{n*t}[/tex]

Putting values and finding P

[tex]A=P(1+\frac{r}{n})^{n*t}\\7000=P(1+\frac{0.06}{52})^{4*52}\\7000=P(1.001)^{208}\\7000=P(1.231)\\P=\frac{7000}{1.231} \\P=5687[/tex]

So, The investment required is: $5687

a car travels from point s at (-5,7) to point t at (-5,-1). if each unit represents 20 miles, how long will it take the car to travel this distance, traveling at 40 miles per hour?

Answers

Answer:

The value is  [tex]t = 4 \ hours[/tex]

Step-by-step explanation:

From the question we are told that

  The initial  position of the car is  [tex]x_i , y_i = (-5,7)[/tex]

   The final position of the car is    [tex]x_f , y_f = (-5,-1)[/tex]

    The speed of the car is [tex]v = 40 \ miles / hour[/tex]

Generally the distance covered by the car along the x-axis is  

      [tex]x = -5 - [- 5][/tex]

=>    [tex]x = 0[/tex]

Generally the distance covered along the y-axis is  

     [tex]y = y_i - y_f[/tex]

=>[tex]y = y_i - [-1][/tex]

=>  [tex]y = 8[/tex]

Generally the resultant distance covered is  

     [tex]R = \sqrt{x^2 + y^2}[/tex]

=>   [tex]R = \sqrt{0^2 + 8^2}[/tex]

=>   [tex]R = 8[/tex]

From the question we are told that 1 unit of the distance covered is  20 miles so  

    8 units is

           [tex]r = 8 *20[/tex]

=>        [tex]r =160 \ miles[/tex]

Generally the time taken is mathematically represented as

       [tex]t = \frac{r}{v}[/tex]

=>    [tex]t = \frac{160}{ 40}[/tex]

=>    [tex]t = 4 \ hours[/tex]

What is the range of the function y=e4x?
Oy < 0
Oy>
O y<4
Oy>4

Answers

9514 1404 393

Answer:

  y > 0

Step-by-step explanation:

The range of the function ...

  y = e^(4x)

is the same as the range of any exponential function:

  y > 0

The function can take on any positive value, but will never be 0 or negative. It has a horizontal asymptote of y=0.

The range of the given function is y > 0.

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given function is,

y = e⁴ˣ

This is an exponential function.

The range of any exponential function is all the real numbers which are greater than 0.

So here also, the range is all the real numbers which are greater than 0.

So range is y > 0.

Hence the correct option is B.

A triangle is formed with side lengths of 5 inches, 12 inches, and 15 inches. Is the triangle a right triangle?

Answers

Answer:

the triangle is not a right angle

Step-by-step explanation:

5²+12²=169

15²=225

The given triangle is not right angle triangle, because the given information of the triangle does not hold the Pythagoras theorem.

What are Pythagorean triplets?  

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,
A triangle is formed with side lengths of 5 inches, 12 inches, and 15 inches.
Verifying whether it is right angle or not,
Hypotenuse = 15
perpendicular = 12
Base = 5

Now,
Pythagoras' theorem is given as,
h² = p² + b²
15² = 12² + 5²
225 ≠ 169

Thus, the given triangle is not right angle triangle, because the given information of the triangle does not hold the Pythagoras theorem.
