If f( x ) = 5x -2, what is f( 3 ) ?

F- 0
G- 8
H- 13
J - 15

Answers

Answer:

H.  13

Step-by-step explanation:

To find the output of a function, substitute the value given in parentheses for x, and do the operations.

Given f(3)

f(3) = 5(3) - 2

f(3) = 15 - 2

f(3) = 13

Answer:

its 13 ^^

Remember alternative exterior angles are congruent... that means for example 12 that the angles are congruent

Also, interior angles are congruent... that means for example 17 the angles are congruent (also 19)

And, vertical angles are also congruent... that means for example in 18 the angles are congruent...

Consecutive angles also are congruent... that means 14

Corresponding angles are also congruent.. that means for example 13

Any other ones that I didn't exactly list... if they look like the ones I DID list then they go under that definition...

Hope this helps :)

Find the 30th term of the following sequence. 1, 7, 13, 19, ... 174 175 180 181.

Answers

Checking if the sequence is an arithmetic sequence 7 - 1 = 6 13 – 7 = 6 Therefore the sequence is arithmetic, with a_0 = 1 and d = 6 a_n = a_0 + (n-1)d a_30 = 1 + (29)(6) = 175 Therefore the 30th term is 175.
the rule is : 6n - 5 to find the 30th term replace n with 30 6× 30 - 5 = 175

On a backpacking trip through Europe, Troy spent 20 Swiss francs to stay one night in a youth hostel. If the foreign exchange rate between the U.S. dollar and the Swiss franc is 1:2.2, how much did Troy spend in U.S. dollars?

Answers

Answer:Hence, Troy spend 9.09 in U.S. dollars.

Step-by-step explanation:

Since the foreign exchange rate between the U.S. dollar and the Swiss franc is 1:2.2.

It means,

1 U.S. dollar = 2.2 Swiss Franc

Now, According to question, Troy spent 20 Swiss francs to stay one night in a youth hostel.

So, 1 Swis Franc = (1)/(2.2)

20 Swiss Franc = (20)/(2.2)=\$9.09

Hence, Troy spend 9.09 in U.S. dollars.
Every US Dollar equals $2.2 in France so 9.09.

A 65.0 gram sample of some unknown metal at 100.0° C is added to 100.8 grams of water at 22.0° C. The temperature of the water rises to 27.0° C. If the specific heat capacity of liquid water is 4.18 J/ (°C × g), what is the specific heat of the metal?2.25 J/ (°C × g).
1.75 J/ (°C × g).
0.444 J/ (°C × g).
0.324 J/ (°C × g).

Answers

heat gained by the metal = heat lost by the water
65.0* Cs * (100.0°C - 27.0°C) = 100.8 g * 4.18 J/(°Cxg) * (27.0°C - 22.0°C)

Cs = 100.8 * 4.18 * 5.0 / (65.0 * 73) J/(°Cxg) = 0.444J/(°Cxg)

Answer: the fhird option, 0.444 J/(°Cxg)

A shopper thought shoes marked $40 the sales tax is 8% how much the shopper pay in all

Answers

so, if I understand correctly the prize before sales tax is 40 dollars and the sales tax is 8%. how much is this?

(8)/(100) *40= (8)/(10) *4=(4)/(5) *4= (16)/(5) =3.2

so the final prize is 40+3.2=43.2
