If n=4x−3, then what is the value of x when n=11?

crimeas [40]

Answer:

x=7/2

Step-by-step explanation:

11=4x−3

Step 1: Flip the equation.

4x−3=11

Step 2: Add 3 to both sides.

4x−3+3=11+3

4x=14

Step 3: Divide both sides by 4.

4x /4 = 14 /4

x= 7/ 2

If cos 37 degrees is close to 4/5, which is closest to the measure of line OP?

geniusboy [140]

We know that ON = 80 cm and ∠ O = 37°.
cos 37° = 4/5
Adjacent / Hypotenuse = cos∠O
80/OP = cos 37°
80/ OP = 4/5
OP = 80 : 4/5 = 80 · 5/4 = 100
Answer:
d. 100 cm.

Here is a growing pattern of sequences:

Nadusha1986 [10]

Answer:

A, C, F

Step-by-step explanation:

The first figure is drawn using 8 squares. The next uses 11 squares, and the one shown in Step 3 uses 14 squares. The numbers of blocks follow the sequence ...

8, 11, 14

which begins with 8 and increases by 3 from one step to the next. This constant increase from one term to the next makes it an arithmetic sequence.

<h3>explicit form</h3>

The general term, an, of an arithmetic sequence can be written in terms of its first term, a1, and its common difference, d, as ...

an = a1 +d(n -1)

When the first term is a1=8, and the common difference is d=3, this becomes ...

an = 8 +3(n -1)

which simplifies to

an = 8 +3n -3 = 3n +5

Written in functional form, these explicit equations are ...

f(n) = 8 +3(n -1) . . . . . matches choice A

f(n) = 3n +5 . . . . . . . . matches choice F

<h3>recursive form</h3>

The recursive form of the definition of a sequence starts with the first term, then tells you how to obtain the next term from that. Here, the first term is ...

f(1) = a1 = 8

and each term is 3 more than the last:

f(n) = 3 +f(n-1) . . . . . . . . . 3 is added to the previous term

Together, this is ...

f(n) = 8, f(n) = 3 +f(n -1) . . . . . matches choice C
