Answer:
13th Amendment- C
14th Amendment- A
15th Amendment- B
Step-by-step explanation:
Answer:
13th C
14th A
15th B
Step-by-step explanation:
You have to think of it in events in order. Slaves can't vote until they're free, so the thirteenth amendment gets rid of slavery. It wouldn't make sense if slaves could vote without other freedoms, so freedoms come first. 14th is B for this reason. Lastly, the fifteenth amendment grants African American men to vote years down the road (women weren't allowed to vote yet at all, so the African American females also didn't have this right)
What represents the recursive formula for the arithmetic sequence an=7-3(n-1)
Answer:
[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} - 3 && \text{for $n \ge 1$}\end{aligned}\right.[/tex].
Step-by-step explanation:
An arithmetic sequence could be defined using only two pieces of information:
The first term of this sequence, [tex]a_{1}[/tex].The common difference between two consecutive terms of this sequence, [tex]d[/tex].The arithmetic sequence in this question is given in the explicit form, [tex]a_{n} = 7 - 3\, (n - 1)[/tex], which is equivalent to [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]. In the explicit form, [tex]a_{1}[/tex] and [tex]d[/tex] are described in the same equation:
[tex]\text{$a_{n} = a_{1} + d\, (n - 1)$ for $n \ge 1$}[/tex].
Compare [tex]a_{n} = a_{1} + d\, (n - 1)[/tex] with [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]: [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex].
When an arithmetic sequence is given in the recursive form, [tex]a_{1}[/tex] and [tex]d[/tex] are specified in two separate equations:
[tex]\left\lbrace\begin{aligned}& a_{1} = a_{1} \\ & a_{n+1} = a_{n} + d && \text{for $n \ge 1$}\end{aligned}\right.[/tex].
In this question, it was found that [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex]. Hence, the corresponding recursive formula for this arithmetic sequence would be:
[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} + (-3) && \text{for $n \ge 1$}\end{aligned}\right.[/tex].
The speed (v) of a gear varies inversely as the number of teeth (t). If a gear that has 48 teeth makes 20 revolutions per minute, how many revolutions per minute will a gear that has 30 teeth make?
I'll give Brainliest! Please no links
Answer:
32 revolutions per minute(rpm)
Step-by-step explanation:
v inversely proportional to t
so if v increases t will decrease and vice versa
inverse equation is xy=k
xy=k
48×20= 960 (revolutions)
then you'll take k(960) and divide it by number of teeth
so..
960/30 = 32 revolutions per minute

Identify the domain of the exponential function shown in the following graph: (2 points)
Answer:
x is greater than or equal to 0.
Step-by-step explanation:
The domain is just your X value. In contrast, the range is your Y value. Since we start at and include 0 on the X axis, we continue forever from there. Therefore, X is greater than or equal to 0.
This question is bothering and hurting my brain a lot: A restaurant has a square floor with an area of 324 m². Sketch the resaurant floor. What are its dimensions?
Answer:
The dimensions are 18m by 18m
Step-by-step explanation:
Since the problem says the floor is square, we know that all 4 sides are equal. The area for a square is one side squared. Since we do not have the actual length per side, we write the following formula: x^2= 324.
From there, we simply take the square root to figure out that one side is 18 meters. Once we know one side, we know all 4 because a square has equal sides. Therefore, the dimensions of the floor are 18m x 18m. I hope this helps!

A collection of 40 dimes and nickels
is worth $2.90. How many nickels are
there? (Hint: In your equation, use
290¢ instead of $2.90.)
9514 1404 393
Answer:
22 nickels18 dimesStep-by-step explanation:
Let d represent the number of dimes (the higher-value coin). Then the number of nickels is 40-d, and the total value in cents is ...
5(40 -d) +10(d) = 290
200 +5d = 290
5d = 90
d = 18
40 -d = 22
There are 22 nickels (and 18 dimes).
_____
Additional comment
If you write the equation in terms of the number of nickels (n), you end up with the equation -5n = -110. The formulation used above avoids negative numbers, which can be confusing for some people.

Find the measure of the missing angles.
56°
102°
d
e
f
Answer:
Step-by-step explanation:
d = 102°
e = 56°
f = 22°
The measurement of each of the angle is -
∠e = 56°
∠d = 102°
∠f = 22°
What are intersecting lines?When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measureGiven are the intersecting lines as shown in the image.
We can write that -
∠e = 56° {vertically opposite angles}
∠d = 102° {vertically opposite angles}
∠f = {180 - (102 + 56)} {vertically opposite angles}
∠f = 22°
Therefore, the measurement of each of the angle is -
∠e = 56°
∠d = 102°
∠f = 22°

prove that 5^(2n - 1) is divisible by 8
Answer:
Step-by-step explanation:
Prove that 52n − 1 is divisible by 8 for all n ∈ N.
Solution
To prove by induction, we must
1. Show it is true for n = 1
2. Assume true for n and prove it is true for n + 1.
Let P(n) be the statement 52n − 1 is divisible by 8.
When n = 1, 52 − 1 = 24, which is divisible by 8.
This proves P(1).
Suppose that P(n) is true, i.e., 52n − 1 is divisible by 8.
Then 52(n+1) − 1 = 52
· 5
2n − 1 = 52
(52n − 1) + (52 − 1).
Note that 52n −1 is divisible by 8 using P(n) and also 52 −1 = 24 is divisible
by 8. Thus we have proved that P(n + 1) is true.
We conclude that P(n) is true for all n ∈ N.

Step-by-step explanation:
FI=6

calculate the length of GI
[tex]\\ \sf\longmapsto GI^2=FI(IH)[/tex]
[tex]\\ \sf\longmapsto GI^2=6(12)[/tex]
[tex]\\ \sf\longmapsto GI^2=72[/tex]
[tex]\\ \sf\longmapsto GI=\sqrt{72}[/tex]
[tex]\\ \sf\longmapsto GI=8.22[/tex]
If FI = 6 and IH = 12. The length of GI = 8.22.
How to estimate the length of GI?Given: FI = 6 and IH = 12
To estimate the length of GI
[tex]$\mathrm{Gl}^{2}[/tex] = FI (IH)
Simplifying the above equation, we get
[tex]$\mathrm{Gl}^{2}[/tex]= 6 (12)
Remove parentheses: (a) = a
Multiply the numbers then, we get
[tex]$6 \cdot 12=72$[/tex]
[tex]$\mathrm{Gl}^{2}[/tex] = 72
GI = [tex]$\sqrt{72}[/tex]
GI = 8.22
Therefore, the length of GI = 8.22.

0.84 x 6 = 5.04
Step-by-step explanation:
5.04 is the answer.
Answer:
Answer B is correct
Step-by-step explanation:
We want to multiply 6 and 0.84
First you have to forget about decimals and multiply those two numbers
084
×6
-----------------
= 504
And then consider about the number of decimal places. According this sum you have 2 decimal places ( 0.84 )
And now you can write the answer as
