Use the quadratic formula to solve x^2 -3x - 5 = 0. Round to two decimal places.
Answer:
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{3+\sqrt{29}}{2},\:x=\frac{3-\sqrt{29}}{2}[/tex]
Step-by-step explanation:
Given the equation
[tex]x^2\:-3x\:-\:5\:=\:0[/tex]
solving with the quadratic formula
[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}[/tex]
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]\mathrm{For\:}\quad a=1,\:b=-3,\:c=-5[/tex]
[tex]x_{1,\:2}=\frac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\cdot \:1\cdot \left(-5\right)}}{2\cdot \:1}[/tex]
[tex]x_{1,\:2}=\frac{-\left(-3\right)\pm \sqrt{29}}{2\cdot \:1}[/tex]
separating the solutions
[tex]x_1=\frac{-\left(-3\right)+\sqrt{29}}{2\cdot \:1},\:x_2=\frac{-\left(-3\right)-\sqrt{29}}{2\cdot \:1}[/tex]
solving
[tex]x=\frac{-\left(-3\right)+\sqrt{29}}{2\cdot \:\:1}[/tex]
[tex]=\frac{3+\sqrt{29}}{2\cdot \:1}[/tex]
[tex]=\frac{3+\sqrt{29}}{2}[/tex]
also solving
[tex]\:x=\frac{-\left(-3\right)-\sqrt{29}}{2\cdot \:\:1}[/tex]
[tex]=\frac{3-\sqrt{29}}{2\cdot \:1}[/tex]
[tex]=\frac{3-\sqrt{29}}{2}[/tex]
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{3+\sqrt{29}}{2},\:x=\frac{3-\sqrt{29}}{2}[/tex]

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!
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.

Which graph represents the function f(x) = |x + 3|?
Answer:
Answer is B
Step-by-step explanation:
If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.
But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.
Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).
What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.
So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.
