Identify the 16th term of a geometric sequence where a1 = 4 and a8 = −8,748.
Step-by-step explanation:
The formula used to determine the terms is
an = a1 × rn - 1
It is given that
a1 = 4
a8 = -8,748
Substituting the values in the formula
-8748 = 4 × r8 - 1
r7 = -8748/4
r7 = -2187
r = -3
So the 16th term is
a16 = 4 × 316-1
a16 = -57395628
Therefore, the 16th term is -57395628.

Which graph represents the piecewise-defined function f(x) = { -x + 4, 0 ≤ X< 3
6,
X ≥ 3
9514 1404 393
Answer:
(d)
Step-by-step explanation:
The second line of the function is ...
f(x) = 6, x ≥ 3
This tells you that portion of the graph is the horizontal line y = 6, extending to the right from x = 3, and that there will be a solid dot at (3, 6).
This shows only on the attached graph.

Step-by-step explanation:
5x^2-9 when x = -2
5(-2)^2-9
I know the answer is 11, but how? When I did it, I got -29 and I don’t know how to get 11. Could someone explain step by step on how to get the correct answer?
5(-2)² - 9
First, solve the one in the bracket which is -2 × -2 which gives us =4
5(4) - 9
Then, multiply 5 with 4 so
20 - 9
Then you'll get 11

Let f(x)=5x^4 and g(x)=e^2x+x. If h is the function defined by h(x)=f(g(x)), which of the following gives a correct expression for h′(x)?
The values of h'(x) is h'(x) = 20 [tex](e^{2x} + x) ^{3}[/tex] (2[tex]e^{2x}[/tex] + 1 ).
Option C is the correct answer.
Given,
f(x)=5x^4 and g(x)=e^2x+x.
If h is the function defined by h(x)=f(g(x)),
We need to find h′(x).
What is the differentiation formula for the following?We have,
dx/dx = 1
d[tex]x^{n}[/tex]/dx = n[tex]x^{n-1}[/tex]
d[tex]e^{x}[/tex]/dx = [tex]e^{x}[/tex]
d[tex]e^{n}[/tex]/dx = [tex]ne^{n}[/tex]
d(cx)/dx = c(dx/dx) = c
We have,
- f(x)=5[tex]x^{4}[/tex] ______(1)
- g(x)=[tex]e^{2x}[/tex]+x ______(2)
- h(x)=f(g(x)) _______(3)
Now,
h(x) = f ( [tex]e^{2x}[/tex]+x )
From (1)
h(x) = 5[tex](e^{2x} + x) ^{4}[/tex] ______(4)
Now,
Differentiate (4)
h'(x) = 5 d[tex](e^{2x} + x) ^{4}[/tex]/dx
h'(x) = 5 x 4 [tex](e^{2x} + x) ^{3}[/tex] d [tex](e^{2x} + x)[/tex] / dx
h'(x) =20 [tex](e^{2x} + x) ^{3}[/tex] ( d[tex]e^{2x}[/tex]/dx + dx/dx )
h'(x) = 20 [tex](e^{2x} + x) ^{3}[/tex] (2[tex]e^{2x}[/tex] + 1 )
Thus the values of h'(x) is h'(x) = 20 [tex](e^{2x} + x) ^{3}[/tex] (2[tex]e^{2x}[/tex] + 1 ).
Option C is the correct answer.

Step-by-step explanation:
Solve for x
5x−4≥12 OR 12x+5≤−4
Please help, I'm stuck and I'm not really getting the hang of this yet.
Answer:
No solution
Step-by-step explanation:
5x−4≥12 AND 12x+5≤−4
solve it separately
5x - 4>=12
add 4 on both sides
5x >= 16
Divide both sides by 5
x > = 16/5
12x+5≤−4
subtract 5 from both sides
12x <= -9
divide both sides by 12
x<= -9/12
x<=-9/12 and x>= 16/5
There is no intersection between the inequalities
so there is no solution

the length and breadth of a piece of land are 20meters and 15 meters respectively. What is the perimeter of this land?
Answer:
20x15=300
When you need to calculate the Length and Width of a piece of land or anything else, all you need to do is multiply the two numbers.
Step-by-step explanation:
When you have 20 units of land in as the length and 15 units of land as width, then you should multiply.
2x4=?
When you do 2x4, you have to do 2+2+2+2=
but, here, you have a piece of land to calculate, so basically, you have to multiply still. In that way, you will be able to get what 20 and 15's product is.
I'm sorry, sometimes I just can't explain that well, but just remember, in these types of problems, just multiply, that is your answer.
Thank You! I hope I made your day just a little better!
