A square has a perimeter of 12x + 52 units. Which expression represents the side length of the square in units?

Mathematics
1 answer:
Gnesinka [82]4 years ago

Answer:

C

Step-by-step explanation:

If a square has 4 sides and the perimeter is 12x + 52, you have to divide 12x + 52 by 4 to get the length of a single side

12x / 4 = 3x

52 / 4 = 13

3x + 13

Vocabulary Drag the words to show how theoretical probability and experimental probability differ. Each word may be used only on
allsm [11]

Answer:

Theoretical  --- probability is based on expected or calculated results.

Experimental  --- probability is based on the actual recorded results of an  experiment.

Step-by-step explanation:

Theoretical assumptions are those hypotheses not proven to be real, whose probabilities of materializing depend on the future confirmation of the premises established. Thus, these theories are established based on different experiences and previous situations, or based on data still not scientifically proven.

Instead, the experimental results are those that have already been confirmed based on tests, tests and experiments that affirm or deny the previously established theories.

F(x)=(x+1)^(5)-5x-2 <br> Find F'(x) and zeros of F'(x)
KiRa [710]
Assuming you mean
f(x)=(x+1)^5-5x-2

first use chain rule on first part
derivitive of (x+1)⁵=5(x+1)⁴ times the derivitive of (x+1) which is 1
the first part is 5(x+1)⁴

derivitive of -5x is -5
derivitive of -2 is 0

we gots
f'(x)=5(x+1)⁴-5
find zeroes
0=5(x+1)⁴-5
5=5(x+1)⁴
1=(x+1)⁴
+/-1=x+1
-1+/-1=x
-2=x or 0=x

f'(x)=5(x+1)⁴-5
zeroes at x=-2 and x=0

The point (2, 3) is on the terminal side of angle Θ, in standard position. What are the values of sine, cosine, and tangent of Θ
stira [4]

Answer:

sin Ф = 3/√13; cos Ф = 2/√13; and tan Ф = 3/2

Step-by-step explanation:

Let's assume we're limiting ourselves to Quadrant I.

Start with the tangent function.  tan Ф = opp / adj.

In this case opp = 3 and adj = 2.  

The length of the hypotenuse is found using the Pythagorean Theorem and is √(3² + 2²) = √13.

Then sin Ф = opp / hyp = 3/√13 or 3√13/13

and

cos Ф = adj / hyp = 2/√13 or 2√13/13

and (as before)

tan Ф =  opp / adj = 3/2

2(4x+3)=10x-2<br> Anyone know how to work this out? <br> Working out needed
Step2247 [10]

Answer:

x = 4

Step-by-step explanation:

1. expand.

8x + 6 = 10x - 2

2. Subtract 8x from both sides.

6 = 10x - 2 - 8x

3. simplify 10x - 2 - 8x to 2x - 2.

6 = 2x - 2

4. Add 2 to both sides.

6 + 2 = 2x

5. Simplify 6+2 to 8.

8 = 2x

6. Divide both sides by 2.

\frac{8}{2}  = x

7. Simplify 8/2 to 4.

4 = x

8. switch sides.

x = 4

Therefor, rhe answer is x=4
