The director of the town's sports programs is studying trends in enrollment over time. She finds that the number of participants

ziro4ka [17]

Answer:

The function is : $y=120(1.10)^x+120+10x$

Step-by-step explanation:

Suppose, after $x$ years, the number of participants in the town's soccer program is $y_{1}$ and in the town's street hockey program is $y_{2}$

This year, there are 120 children participating in each program.

The number of participants in the town's soccer program increases by 10% each year.

Using the exponential growth formula, the number of participants in the town's soccer program after $x$ years will be.....

$y_{1}=120(1+0.10)^x\\ \\ y_{1}=120(1.10)^x$

The number of participants in the town's street hockey program increases by 10 children each year.

So, the number of increased participants in $x$ years $=10x$

Thus, the number of participants in the town's street hockey program after $x$ years will be.....

$y_{2}=120+10x$

If the total number of children participating in the two programs is represented as $y$ , then.....

$y= y_{1}+y_{2}\\ \\ y=120(1.10)^x+120+10x$

So, the function that can be used to predict the total number of children participating in the town's soccer and street hockey programs in x years will be: $y=120(1.10)^x+120+10x$

The height of a triangle is 3cm less than twice the base. The area is 10cm2

Kamila [148]

Answer:

The base is 4cm and the height is 5cm.

Step-by-step explanation:

This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:

$H=2B-3$

and

$\frac{B \times H}{2}=10$

Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:

$\frac{B(2B-3)}{2}=10\\\frac{2B^2-3B}{2}=10\\2B^2-3B=20\\2B^2-3B-20=0\\(2B+5)(B-4)=0\\B= - \frac{5}{2},4$

In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:

$H=2(4)-3\\H=8-3\\H=5$
