Answer:

37, 38, and 39

Step-by-step explanation:

Write the equation by converting words into math symbols:

  • consecutive means n, n+1, and n+2
  • subtract -
  • product *
  • result is =

This means "the product of the smaller two" is n(n+1).

This also means "the product of the greater two" is (n+1)(n+2)

They are subtracted from each other and equal to 76. So it becomes

(n+1)(n+2) - n(n+1) = 76

Write and solve:

(n+1)(n+2) - n(n+1) = 76\\n^2+n+2n+2-n^2-n=76\\n+2n+2-n=76\\2n+2=76\\2n=74\\n=37

The smallest number is 37. The next is 38. The last is 39.

Graph the hyperbola with equation quantity x minus 1 squared divided by 49 minus the quantity of y plus 3 squared divided by 9 e
Sliva [168]

Answer:

See attached diagram

Step-by-step explanation:

You are given the equation of hyperbola

\dfrac{(x-1)^2}{49}-\dfrac{(y+3)^2}{9}=1

From this equation,

  • the center of hyperbola is at point (1,-3);
  • the real semi-axes a^2=49\Rightarrow a=7;
  • the imaginary semi-axes b^2=9\Rightarrow b=3.

Draw two parallel lines x=1 and y=-3 (they intersect at the center of hyperbola), then on horizontal line match two hyperbola's vertices (7 units to the left and 7 units to the right from the center). Then draw two branches of hyperbola (one in negative direction and one in positive direction).

60 is 25% of what number<br><br> 12 is 24% of what number
mojhsa [17]

60 is 25% of 240 and 12 is 24% of 50

25% is a fourth of 100%. So you want to find what number 60 is a fourth of. Multiply 60 by 4.
60x4=240

24% is 4.17th of 100%. Multiply 12 by 4.17
12x4.17=50

Please quickly help!! I will Mark brainliest, What is the inverse of the function f(x) = x +3? Thank you!
Irina18 [472]

Answer:

Mark me as Brainliest

fx^{-1} (x)=x+3

Step-by-step explanation:

To find the inverse of a function, just “trade” x and y and solve for the “new” y. The graph of the inverse is the reflection of the original function over the line y=x.

Rewrite the function

f(x)=x+3

as the equation, y=x+3

Trade x and y.

X=y+3

The symbol for the inverse if fx^{-1} (x)

fx^{-1} (x)=x+3
