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

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

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
Answer:
The radius of the circle is:
[tex]r=4[/tex] unitsStep-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?
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

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?
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!
