The turning point is the vertex of the parabola, which occurs at point (1, 4).   The roots are the areas where the graph crosses the x-axis, referred to as the x-intercepts. The graph crosses the x-axis at points (-1, 0) and (3, 0).

hi could someone explain this??

im thinking it is J=50(15)^t??? ​

Answers

Answer:

J=15t+50

Step-by-step explanation:

The equation to represent this situation will be in the form J=mt+b where b is the starting value of love units, m represents the "love units" that are multiplied by the number of week, t is the number of weeks, and J represents Jack's love at that specific week.

The equation becomes: J=15t+50

To check, the equation should equal 50 when t=0, 65 when t=1, and 80 when t=2.

Checking t=0:

J=15(0)+50=0+50=50

Checking t=1:

J=15(1)+50=15+50=65

Checking t=2:

J=15(2)+50=30+50=80

The equation J=15t+50 does model the behavior of Jack's love at any week t based on the given data. Note that the equation used was based on slope intercept form (y=mx+b) due to the given data having a linear relationship.

Answers

Answer:

10 feet tall

Step-by-step explanation:

(Triangle problem was answered in a previous question)

So like before, we have a ratio: 1.5inches:2.5feet

We have a starting value as well: 6 inches

All we have to do is convert from inches to feet (not with a real life equation, but with the given equation)

To begin, dvide 6 by 1.5

6inches/1.5inches = 4 (The units canceled out during division)

Not multiply by the ratio:

4 * 2.5feet = 10 feet (It takes the units in feet)

Therefore, the tree is actually 10 feet tall.

Tap X can fill a bath in 12 minutes.
Tap Y can fill a bath in 6 minutes.
How long will it take to fill the bath with both taps running at the same time?

Answers

Answer:  4 minutes

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

Explanation:

Let's say that this tub is 72 gallons. I picked this number since 12*6 = 72. You can pick any number you want, but I picked this number so we end up with whole number results as shown below.

Tap X can fill the 72 gallon tub in 12 minutes. Its rate is 72/12 = 6 gallons per minute. Tap Y has a rate of 12 gallons per minute because 72/6 = 12.

Add the two unit rates: 6+12 = 18

If the two taps are opened at the same time, then they will work at a rate of 18 gallons per minute.

Let x be the number of minutes. The expression 18x represents how much of the tub is full after x minutes. Set this equal to the 72 we started with earlier and solve for x.

18x = 72

x = 72/18

x = 4

It will take 4 minutes if both taps are running at the same time.

ReWrite 2/3 and 3/4 with a common denominator

Answers

Answer:

8/12 and 9/12

Step-by-step explanation:

Answer: 8/12 and 9/12

2/3 = 8/12 and 3/4 = 9/12

To get two fractions with common denominators you can find the least common multiple of the denominators or you can multiply 2/3 x 4 and 3/4 x 3

The lowest common denominator between 4 and 3 is 12

To get from 4 to twelve we multiplied by 3. Whatever you do to the bottom you do to the top. The top number is 3.

3 x 3 = 9

So your new fraction is 9/12. If you simply this you get 3/4 so this checks out ✔️

Now we need to do the other fraction

To get to from 3 to twelve we multiply by 4

3 x 4 = 12

Whatever you do to the bottom you have to do it the same to the top

2 x 4 = 8

Now you get 8/12. 8/12 simplified is 2/3 so this Plato’s checks out ✔️
