4) An arithmetic sequence has a 7th term of 54 and a 13th term of 94. Find the common difference
Please answer!!
Answer:
20/3
Step-by-step explanation:
Every nth term takes the form of a + n*d, where a is the first term.
So 7th term = (54 = a + 7d), 13th term = (94 = a + 13d).
equate them both:
94 - 13d = 54 - 7d
40 = 6d
d = 40/6

Answer: -15
Step-by-step explanation:
f(-8) is the value of y / f(x) when x = -8 in the function f(x)
f(-8) = -5
g(4) is the value of y / f(x) when x = 4 in the function g(x)
g(4) = 5
-1 * f(-8) - 4 * g(4)
Substitute -5 for f(-8) and 5 for g(4)
-1 * -5 - 4 * 5 (evaluate, note: remember order of operations)
5 - 4 * 5
5 - 20
-15

Describe these points with a double inequality
These points can be described the following double inequality: -3≤x≤13.
InequalitiesInequality is a mathematical expression that does not present equality between both sides. It is represented by symbols: <, ≤, > and ≥.
When the variable x is between the both extremes, the inequality will be called double inequality. Therefore, the double inequality can be written in the form below .
a<x<b is equivalent to x>a and x<ba>x>b is equivalent to x<a and x>ba≤x≤b is equivalent to x≥a and x≤ba≥x≥b is equivalent to x≤a and x≥bAs the interval is represented by a closed dot, your interval inequality must be represented by signs ≤ or ≥.
Thus, the points of this question can be described as: -3≤x≤13.

Deduce the minimum value of sinx+cosx and give the corresponding values of x, for x E [-360;360]
The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different, [tex]-\pi/2, \pi[/tex] for sine and cosine respectively.
The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.
Here is a procedure, first take a derivative
[tex]\frac{d}{dx}(\sin x+\cos x)=\cos x -\sin x[/tex]
Then compute critical points of a derivative
[tex]\cos x-\sin x=0\implies x_1=\frac{\pi}{4},x_2=\frac{5\pi}{4}[/tex].
Then evaluate [tex]\sin x +\cos x[/tex] at [tex]x_1,x_2[/tex].
You will obtain global maxima and global minima [tex]\sqrt{2}, -\sqrt{2}[/tex] respectively.
The answer is [tex]-\sqrt{2}[/tex].

A rectangle’s length is represented by the expression (3x + 9). The width is represented by the expression (2x – 5). Which expression represents the perimeter of the rectangle?
A.
5x + 4
B.
5x + 14
C.
10x + 8
D.
10x + 13
Answer:
Step-by-step explanation:
The perimeter of a rectangle is
P=2(L+W)
We are given L=3x+9 and W=2x-5 so
P=2(3x+9+2x-5)
P=2(5x+4)
P=10x+8

Step-by-step explanation:
solve for 26 - 4s = 9s.
26-4s=9s
⇔26=9s+4s
⇔26=13s
⇔s=2
Answer:
s = 2
Step-by-step explanation:
26 - 4s = 9s
add 4s to 4s and 9s
that equals 13
26/13 = 13s/13
s = 2

what is the 37th term of the arithmetic sequence with the first term -39 and the common difference of 8
257
241
227
249
Answer:
249
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
an = a1+d(n-1)
a1 is the first term so a1 = -39
d is the common difference so d = 8
n is the term number so n = 37
a37 = -39+8(37-1)
= -39+8(36)
= -39+288
=249

PLEASE I WILL DO ANYTHING JUST I NEED TO GET THIS LAST QUESTION DONE
ANSWER:
= 158 square inches
STEP BY STEP:
okay! so basically I like to ignore the net figure (just my personal opinion)
so we know that the rectangular prism has six sides (one top, one bottom, one front, one back, and two on each side)
so using that information, we can solve for the surface area!
FRONT AND BACK AREA:
- to solve for this area, we are going to take the 8" and multiply it by 5" to find the surface area of the front and the back panels
8*5 = 40 BUT WE HAVE TWO PANELS WITH THIS AREA
40*2 = 80
TOP AND BOTTOM AREA:
- to solve for this area, we are going to take 3" and multiply it by 8" to find the surface area of the top and bottom panels
3*8 = 24 BUT WE HAVE TWO PANELS WITH THIS AREA
24*2 = 48
SIDE AREA:
- to solve for this area, we are going to take 3" and multiply it by 5" to find the surface area of both the left and right sides
3*5 = 15 BUT WE HAVE TWO PANELS WITH THIS AREA
15*2 = 30
So now we have all of our areas and we will just add them together!
80+48+30
= 158 square inches

PLEASE HELP QUICK!!
Answer:
2/3+2/3=4/3 or 1 1/3
Step-by-step explanation:
I figured it out!!
it should be greater than. the reasoning for this is if you equally split a rectangle into 3 pieces and then also split the same sized rectangle into equal pieces then which pieces would be bigger? the Rectanhle that is split into 3! this is because you have less pieces to split the rectangle into so the less you have too split the rectangle to larger the pieces are!!
Answer:
2/3+2/3 is greater than 1 1/4, so Edward does not have enough oil
Step-by-step explanation:
2/3+2/3=4/3, or 1 1/3
So now it's is 1 1/3 greater than or less than 1 1/4, which is just a matter of if 1/3 is greater than 1/4. 1/3 is 0.33 repeating, and 1/4 is 0.25, so 1/3 is greater than 1/4
1 1/4 is the amount of oil he has, and 1 1/3 is the amount required, which is more than he has so therefore he can't make 2 batches
