9) State the coordinates of the endpoints of a<br> line segment that intersects the y-axis.
eduard

Answer:

(5,4) and (3,4)

Step-by-step explanation:

A line segment has 2 end points which can be denoted as:

(x_1,y_1) and (x_2,y_2)

When this line segment intersects at y.

This means that the coordinate on the y axis is the same at both end points

i.e.

y_1 = y_2 = y

(x_1,y_1) and (x_2,y_2) becomes (x_1,y) and (x_2,y)

x1 and x2 can be any value but the y value must remain unchanged

Using the above analysis, a possible coordinate is:

(5,4) and (3,4)

Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form (x_1,y)<em> and </em>(x_2,y)<em />

Take for instance, another possible pair is:

(1,-3) and (0,-3)

How do you do this question?
mihalych1998 [28]

Answer:

C) π/6

Step-by-step explanation:

The area under the curve from x=-π/2 to x=k is 3 times the area under the curve from x=k to x=π/2.

\int\limits^k_{-\frac{\pi }{2}} {cos\ x} \, dx = 3\int\limits^{\frac{\pi }{2}}_k {cos\ x} \, dx\\sin\ x\ |^{k}_{-\frac{\pi }{2}} = 3\ sin\ x\ |^{\frac{\pi }{2}}_k\\(sin\ k - (-1)) = 3\ (1 - sin\ k)\\sin\ k + 1 = 3 - 3\ sin\ k\\4\ sin\ k = 2\\sin\ k = \frac{1}{2}\\k = \frac{\pi}{6}

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find
notsponge [240]
So we need to cover 5.5% into a decimal. 

0.055 = 5.5%

The house value is 120,000.
So 

(1.055x) * (120,000)= 

So

f(x)=1.055x * 120,000
