  37/45 ≈ 0.822

Step-by-step explanation:

The formula for an exponential relation is ...

  y = a·b^x

This question is asking for the value of b. It can be found by substituting the given values of x and y, and taking the ratio of the resulting equations.

  90 = a·b^15

  74 = a·b^16

Dividing the second equation by the first, we have ...

  74/90 = (a·b^16)/(a·b^15)

  74/90 = b

The decay factor is 74/90 = 37/45 ≈ 0.822

37/45=0.822 this is my answer

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
