The current value of a future sum of money. The Present Value allows us to calculate what is the value of today that has an amount of money that we will not receive right now but later, in the future.
Present value seeks to reflect that it is always better to have an amount of money today than to receive it in the future. In fact, if we have the money today we can do something to make it productive, such as investing in a company, buying shares or leaving it in the bank that pays us interest, among other options. In addition, even if we do not have a certain plan to invest the money we can simply spend it to satisfy our tastes and we do not have to wait to receive the money in the future.

Which function has two x-intercepts, one at (0, 0) and one at (4, 0)? f(x) = x(x − 4) f(x) = x(x + 4) f(x) = (x − 4)(x − 4) f(x) = (x + 4)(x + 4)
If you want a polynomial to have the x-intercepts of your choice, you simply have to build a polynomial by multiplying pieces like [tex](x-x_k)[/tex] where [tex]x_k[/tex] is the x-intercept you want.
So, if you want x-intercepts 0 and 4, you have to build the polynomial
[tex](x-0)(x-4) = x(x-4)[/tex]
The function that has x-intercepts at (0, 0) and (4, 0) is f(x) = x (x − 4).
Option A is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The x-intercepts of a function are the points where the graph of the function crosses the x-axis.
At these points, the value of the function is zero.
To have x-intercepts at (0, 0) and (4, 0), the function must be zero when x is equal to 0 and 4.
Let's evaluate the given options:
f(x) = x(x − 4):
This function is zero at x = 0 and x = 4, so it has x-intercepts at (0, 0) and (4, 0).
f(x) = x(x + 4):
This function is zero at x = 0 and x = -4, so it does not have an x-intercept at (4, 0).
f(x) = (x − 4)(x − 4):
This function is zero at x = 4, but it also has a double root at x = 4, so it only has one x-intercept at (4, 0).
f(x) = (x + 4)(x + 4):
This function is zero at x = -4, but it does not have an x-intercept at (0, 0).
Therefore,
The function that has x-intercepts at (0, 0) and (4, 0) is f(x) = x(x − 4).

Answer:
h = 10 m
Step-by-step explanation:
We are given the following formula of the area of a trapezoid:
[tex]A=\frac{1}{2} (b+c)h[/tex]
where [tex]h[/tex] is the height of the trapezoid and [tex]b[/tex] and [tex]c[/tex] are its bases.
Re-arranging the given formula to solve for h:
[tex]A=\frac{1}{2} (b+c)h[/tex]
[tex]2A=(b+c)h[/tex]
[tex]h=\frac{2A}{(b+c)}[/tex]
Finding the height of the trapezoid given the bases 20 m, 7 m and area 135m^2.
[tex]h=\frac{2 \times 135}{(7+20)}[/tex]
h = 10 m
ANSWER
h=10m
EXPLANATION
The given formula is
[tex]A = \frac{1}{2} (b + c)h[/tex]
We multiply through by 2 to get,
[tex]2A =(b + c)h[/tex]We divide both sides by (b+c) to get,
[tex] \frac{2A}{b + c}=h[/tex]
Or
[tex]h=\frac{2A}{b + c} [/tex]
[tex]h=\frac{2 \times 135}{20 + 7} [/tex]
We simplify to get,
[tex]h=\frac{270}{27} [/tex]
Therefore
[tex]h = 10[/tex]
Now if b=20, c=7 and A=135, then,
Indicate a general rule for the nth term of this sequence.
-6a, -3a, 0a, 3a, 6a. . .
an = 3an + 9a
an = -3an - 9a
an = -3an + 9a
an = 3an - 9a
difference=3a
so an=-6a+(n-1)3a
=3an-9a
Answer:
Option D. [tex]a_{n}=3an-9a[/tex] is the answer.
Step-by-step explanation:
The given sequence is -6a, -3a, 0a, 3a, 6a...........
Since the given sequence is having a common difference d = -3a - (-6a) = -3a + 6a = 3a
Therefore, the given sequence is an arithmetic sequence.
And for an arithmetic sequence general rule or explicit formula is given by
[tex]T_{n}=a+(n-1)d[/tex]
Where a = first term of the sequence
d = common difference
n = number of term which we have to find
Now we put the values from the given sequence
[tex]T_{n}=-6a+(n-1)3a[/tex]
[tex]T_{n}=-6a+3an-3a[/tex]
[tex]T_{n}=3an-9a[/tex]
Option D. [tex]a_{n}=3an-9a[/tex] is the answer.
Which functions have a y-intercept that is greater than the y-intercept of the function g(x) = |x + 3| + 4? Check three options.
f(x) = –2 (x – 8)2
h(x) = –5 |x| + 10
j(x) = –4(x + 2)2 + 8
k(x)=1/4(x-4)^2+4
m(x)=1/4 |x-8| +6
Answer:
h(x) = –5 |x| + 10
k(x)=1/4(x-4)^2+4
m(x)=1/4 |x-8| +6
Step-by-step explanation:
The given function is:
g(x) = |x + 3| + 4
At y-intercept x=0,
g(0) = |0 + 3| + 4
g(0) = 3 + 4=7
The y-intercept of this function is 7.
We look for the functions with y-intercepts greater than 7.
[tex]f(x)=-2(x-8)^2[/tex]
[tex]f(0)=-2(0-8)^2[/tex]
[tex]f(0)=-128[/tex]
h(x) = –5 |x| + 10
h(x) = –5 |0| + 10=10
[tex]j(x)=-4(x+2)^2+8[/tex]
[tex]j(0)=-4(0+2)^2+8=-8[/tex]
[tex]k(x)=\frac{1}{4}(x-4)^2+4[/tex]
[tex]k(0)=\frac{1}{4}(0-4)^2+4=8[/tex]
m(x)=1/4 |x-8| +6
m(0)=1/4 |0-8| +6=8
Answer with explanation:
The given function is
g(x)=|x+3|+4
The meaning of Y intercept is the distance between origin and Point where the curve cuts Y axis.
In , g(x), put x=0
g(0)=|0+3|+4
=3+4
=7
So, Length of Y intercept =7 unit
2.
f(x)=-2(x-8)²
f(0)=-2×(0-8)²
= -2 × 64
= -128
Length of Y intercept =-128 unit
3.
h(x)=-5|x|+10
h(0)=-5 × |0| +10
=10
Length of Y intercept =10 unit
4.
j(x)=-4(x+2)²+8
j(0)=-4×(0+2)²+8
=-4 × 4+8
= -16 +8
= -8
Length of Y intercept =-8 unit
4.
[tex]\rightarrow k(x)=\frac{1}{4} \times (x-4)^2+4\\\\\rightarrow k(0)=\frac{1}{4} \times (0-4)^2+4\\\\\rightarrow k(0)= 4+4\\\\=8[/tex]
Length of Y intercept =8 unit
5.
[tex]\rightarrow m(x)=\frac{1}{4} \times |x-8|+6\\\\\rightarrow k(0)=\frac{1}{4} \times |0-8|+6\\\\\rightarrow k(0)= 2+6\\\\=8[/tex]
Length of Y intercept =8 unit
⇒ h(x),k(x) and m(x) has y intercept greater than y-intercept of the function g(x) = |x + 3| + 4.

b. (8_/`k)^(-1)
c. k^(-1/8)
d. none of the above
* _/` is a radical with 8 as the index and k as the radicand
The first option is correct: we have
[tex]\left(k^{\frac{1}{8}}\right)^{-1} = \dfrac{1}{k^{\frac{1}{8}}} = \dfrac{1}{\sqrt[8]{k}},\quad \left(k^{-1}\right)^{\frac{1}{8}} = \left(\dfrac{1}{k}\right)^{\frac{1}{8}} = \dfrac{1}{\sqrt[8]{k}}[/tex]
The second option is also correct, because it simply applies the definition

The third option is also correct, because it applies the rule
[tex](a^b)^c = a^{bc}[/tex]
The expressions equivalent to (k^(1/8))^(-1) are (k^(-1))^(1/8) and k^(-1/8), matching options a and c from the given choices. These are determined by correctly applying the exponent multiplication rule.
Explanation:The student is dealing with an expression involving exponents and radicals, specifically focused on understanding the rules for combining and simplifying these expressions. The expression in question is (k^(1/8))^(-1), which we'll simplify in a step-by-step fashion.
The rule of exponents we need to apply here is (a^m)^n = a^(m*n). When applying this rule to the given expression we get:
(k^(1/8))^(-1) = k^(1/8 * -1)
Simplify the exponent:
k^(1/8 * -1) = k^(-1/8)
So, the equivalent expression is:
k^(-1/8)

A circle with radius of 2cm sits inside a circle with radius of 4cm What is the area of the shaded region
The area of the shaded region between a larger circle with a radius of 4 cm and a smaller circle with a radius of 2 cm is 12π cm². This is calculated by subtracting the area of the smaller circle from the area of the larger circle.
This concerns the area of the shaded area between two circles, one with a radius of two centimetres and the other with a radius of four centimeters.
In order to determine this, we first compute the area of each circle using the formula πr², where r is the circle's radius.
Let's start by calculating the area of the bigger circle: π(4cm)² = 16π cm² is the area.
In a similar manner, we can calculate the smaller circle's area: π(2cm)² = 4π cm² is the area.
The area of the shaded region is equal to the area of the larger circle minus the area of the smaller circle, or area = 16π cm² - 4π cm² = 12π cm².

You are looking for the x values of this "rule". It gives you the y-values so all you have to do is plug the y-values into the rule and solve for x
y = 4 so...
4 = x + 3
4 - 3 = x + (3-3)
1 = x + 0
x = 1
When y is 4 then x is 1
y = 8 so...
8 = x + 3
8 - 3 = x + (3 - 3)
x = 5
When y is 8 then x is 5
y = 5 so...
5 = x + 3
5 - 3 = x + (3 - 3)
2 = x + 0
x = 2
When y is 5 then x is 2

The local hamburger shop sold a combined total of 625 hamburgers and cheeseburgers on Friday . There were 75 fewer cheeseburgers sold than hamburgers how many hamburgers were sold on Friday ?
By setting up a system of equations, it was determined that the local hamburger shop sold 350 hamburgers on Friday.
Explanation:To determine how many hamburgers and cheeseburgers were sold on Friday at the local hamburger shop, we can set up a system of equations based on the information given. Let H represent the number of hamburgers sold and C represent the number of cheeseburgers sold. According to the problem, H + C = 625 and H = C + 75.
To find the number of hamburgers, we replace C in the first equation with H - 75 from the second equation, so we have H + (H - 75) = 625. Simplifying this, we get 2H - 75 = 625. Adding 75 to both sides gives us 2H = 700. Dividing both sides by 2 gives H = 350. Therefore, 350 hamburgers were sold on Friday.
