Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7) ?
vitfil [10]
Assume that f(5)=8. So, (5, 8) is a point in the graph of f.

For g(x) to give us 8, we need x to be 12, because in that case we would have:

      g(12)=f(12-7)=f(5), which is 8. Thus, (12, 8) is a point on the graph of g.


Comparing (5, 8) in f, and (12, 8) in g, we can see that the graph of g is the graph of f shifted 7 units to the right.


Answer: <span>C) The graph of g(x) is the graph of ​f(x)​ translated 7 units right.</span>

Gold-192 is a radioactive isotope with a half-life of 4.95 hours. How long will it take for a 15 gram sample of Gold-192 to deca
aksik [14]

The answer should be A. In order to solve these half-life problems, I encourage you to find an algebra calculator online, and plug in these numbers. The remaining grams goes in front, so 3.


The entire equation should look something like 3 = 15(1/2)^t/4.95


The 4.95 represents how long it takes before the sample halves, t is your answer, 1/2 represents the value halving every 4.95 hours, 15 is the initial sample size, and 3 is the end result that remains.


The overall answer should be about 11.5 hours, as per an algebra calculator.

Hope this helps solve any other similar problems

The digits of a two-digit number differ by 3. If the digits are interchanged, and the resulting number is added to the original
Zanzabum

Answer:

The original number could be 85.

Step-by-step explanation:

Let the 2 digits be x and y.

Let the number be xy then, assuming that x is the larger digit:

x - y = 3.

x = y + 3

Also

10y + x + 10x + y = 143

Substituting for x:

10y + y + 3 + 10(y + 3) + y = 143

22y + 33 = 143

22y = 110

y = 5.

So x = y + 3 = 8.

Is segment ST tangent to circle P1
malfutka [58]

Answer:

B . Yes

Step-by-step explanation:

Recall: a tangent of a circle is perpendicular to the radius of a circle, forming a right angle at the point of tangency.

Therefore, if segment ST is tangent to circle P, it means that m<T = 90°, and ∆PST is a right triangle.

To know if ∆PST is a right triangle, the side lengths should satisfy the Pythagorean triple rule, which is:

c² = a² + b², where,

c = longest side (hypotenuse) = 37

a = 12

b = 35

Plug in the value

37² = 12² + 35²

1,369 = 1,369 (true)

Therefore we can conclude that ∆PST is a right triangle, this implies that m<T = 90°.

Thus, segment ST is a tangent to circle P.
