Dos numeros naturales se diferencian en 7 unidades y la suma de sus cuadrados es 289

Mathematics
1 answer:
NeTakaya3 years ago
6 0

Answer:

15 y 8

Step-by-step explanation:

y = x - 7

x² + y² = 289

sustituir: x² + (x - 7)² = 289

distribuir: x² + x² - 14x + 49 = 289

sustraer + simplificar: 2x² - 14x - 240 = 0

dividir: x² - 7x - 120 = 0

x² - 15x + 8x - 120 = 0

(x - 15)(x + 8) = 0

x = 15, x = -8 --> x ≠ -8 porque -8 no es naturales

sustituir: y = 15 - 7

simplificar: y = 8

8. If k = log, 3 then log, 48 =<br> 16<br> (1) 2k +3<br> (3) k +8<br> (2) 3k +1<br> (4) k +4
vekshin1

assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]

given log(ab) = log(a) + log(b)

log_2(48) = log_2(3) + log_2(16)

While shopping at Walmart, I had the option to buy either a 12 pack of Soda for $13, or I could buy a 24 pack for $24. Based on
ira [324]

Answer:

The 24 pack for 24 dollars!

Step-by-step explanation:

This is because you see that 12 is 1/2 of 24 and if you do 13x2 you get 26$ so for the 12 pack if you double it you will be paying 2$ more than if you got the OG 24 pack

Darragh has a Golden Eagle coin in his collection with a mass of 13.551 g. An uncirculated Golden Eagle coin has a mass of 13.71
Sav [38]

The mass lost by Darragh's coin is 0.164 g

<u>Solution:</u>

Given that Darragh has a Golden Eagle coin in his collection with a mass of 13.551 g

An uncirculated Golden Eagle coin has a mass of 13.715 g

To find: mass lost by Darragh's coin

From given question,

Darrangh has coin of mass = 13.551 g

Golden Eagle coin mass = 13.715 g

Darrangh's coin lost mass = 13.715 - 13.551 = 0.164

Thus mass lost by Darragh's coin is 0.164 g

Given the following prescription formula, what is the ratio strength (nearest whole number) of methylcellulose in the finished p
Mamont248 [21]

Answer:

147

Step-by-step explanation:

Given:

Progesterone =  3.8 g

Glycerin = 7 mL

2% methylcellulose solution 50 mL

Cherry syrup ad = 90 mL

Now,

The total volume of the solution = 7 + 50 + 90 = 147 mL

Also,

2% methylcellulose solution 50 mL is concluded as:

the volume of  methylcellulose in the solution is 2% of the total volume of the solution

thus,

volume of methylcellulose = 0.02 × 50 mL = 1 mL

Therefore,

Ratio strength of methylcellulose in the finished product

=\frac{\textup{volume of methylcellulose}}{\textup{ total volume of the solution}}

or

= \frac{\etxtup{1}}{\textup{ 147}}

Hence, the answer according to the question is 147
