<h3>3 answers:  Choice A, choice D, choice F.</h3>

=======================================================

Explanation:

Let's go through the answer choices to see which are true or which are false.

To help us out, we'll use the graph which I've posted below (attached image).

  • Choice A is true because plugging t = 0 into the function leads to h = 6. The graph shows the y intercept is 6. This is where the ball starts.
  • Choice B is false. The graph shows two x intercepts, but the negative root isn't useful (we cannot have a negative time value). So we really only have one useful root. This is where the ball hits the ground.
  • Choice C is false. It's actually the other way around, where h increases first, then decreases. In other words, the ball goes up before it comes back down (instead of going down first and then popping back up). Refer to the graph below.
  • Choice D is true. Refer to the graph below. We can determine this in a non-visual way by noticing the leading term -16t^2 has a negative coefficient. A negative leading coefficient means the parabola opens downward to produce a highest point at the vertex.
  • Choice E is false. This contradicts choice which was shown to be true.
  • Choice F is true. The -16 refers to half of 32 ft/s^2, which is the acceleration of gravity. This value is approximate. Having an acceleration of 32 ft/s^2 means the ball's speed increases by 32 ft/s for each second.

Bess has $2.80 in quarters and dimes. The number of dimes is 7 less than the number of quarters. Find the number of quarters and
Nezavi [6.7K]

Answer:

3 dimes and 10 quarters

Step-by-step explanation:

If you add 7 dimes, then the number of dimes and quarters is the same, and the total increases to $3.50. A dime and a quarter have a value together of $0.35. Since there are equal numbers, the value $3.50 must be made up of some quantity of groups with a value of $0.35. That number of groups must be ...

... $3.50/$0.35 = 10

Thus, there are 10 quarters and 10-7 = 3 dimes.

_____

<em>Using an equation</em>

Let q represent the number of quarters. Then the amount Bess has is ...

... 0.10(q -7) +0.25q = 2.80

... 0.35q - 0.70 = 2.80

... 0.35q = 3.50 . . . . . add 0.70 . . . . . . . this should look familiar

... q = 3.50/0.35 = 10

Choose the correct proportions.
cestrela7 [59]

Answer:

Options A, B and C are CORRECT PROPORTIONS

Step-by-step explanation:

Option A

3:5 = 6:10

The LHS must equal the RHS

3:5 is in it's lowest term.

6/10 will be in it's lowest term by dividing the numerator and denominator by 2.

6/10 = 3/5

Option B

3/6 and 5/10.

Diving 3/6 fractions by 3

= 1/2

Dividing 5/10 fraction by 5

= 1/2

Option C

Dividing 6/3 by 3 = 2

Dividing 10/5 by 5 = 2

Thats how you work through equivalent proportional fractions
