Answer:

1053 members under 25 years.

Step-by-step explanation:

We have been given the total number of students: 4680

\frac{3}{8}\text{aged}25-59

That means in 25-59 there will be:

4680\cdot\frac{3}{8}=1755

And \frac{2}{5}\text{are over}60\text{years}

That means over 60 years will be:

4680\cdot\frac{2}{5}=1872

That means from total 1755+1872=3627

That means 4680-3627=1053 are remaining

And hence, 1053 members are under 25 years.

Fill in the blanks.<br><br> (x+_)^2=x^2+14x+_
Serga [27]

Step-by-step explanation:

(ax + b)² = a²x² + 2abx + b²

In this case, a = 1, so:

14 = 2b

b = 7

(x + 7)² = x² + 14x + 49

Find the point at which the line with parametric equations x = 2 3t, y =-4t, z =5 t intersects the plane 4x 5y -2z=18
sashaice [31]

It looks like you have

\begin{cases}x=2+3t\\y=-4t\\z=5+t\end{cases}

Substituting these in to the plane equation, we have

4x+5y-2z = 4(2+3t) + 5(-4t) - 2(5+t) = -2-10t = 18 \\\\ \implies-10t = 20 \implies t = -2

When t=-2, we get the point

\begin{cases}x=2+3(-2)\\y=-4(-2)\\z=5+(-2)\end{cases} \implies (x,y,z) = \boxed{(-4,8,3)}

ASAP PLEASEwrite an equation for the line that is parallel to tue given line and that passes through the given point. y=-5x+3; (
max2010maxim [7]

Answer:

y=-5x-27

Step-by-step explanation:

Since we are finding a parallel line, the slopes will be the same, so the second equation will also have a slope of -5.

Then, to find the y-intercept, we can use the point given and plug in.

y=-5x+b

3=-5(-6)+b

3=b+30

b=-27

So the equation comes out to be y=-5x-27

We can check by plugging in the given point again.

3=-5(-6)-27

3=30-27

3=3
