g The altitude of a triangle is increasing at a rate 2 inch/hour while the area of the triangle is decreasing at a rate of 0.5 s

zubka84 [21]

Answer:

The base of the triangle is decreasing at a rate of 1.4167 inch/hour.

Step-by-step explanation:

Area of a triangle:

The area of a triangle of base b and height h is given by:

$A = bh$

In this question:

We have to derivate the equation of the area implicitly in function of time. So

$\frac{dA}{dt} = b\frac{dh}{dt} + h\frac{db}{dt}$

The altitude of a triangle is increasing at a rate 2 inch/hour while the area of the triangle is decreasing at a rate of 0.5 square inch per hour.

This means that:

$\frac{dh}{dt} = 2, \frac{dA}{dt} = -0.5$

At what rate is the base of the triangle is changing when the altitude is 6 inch and the area is 24 square inch?

This is $\frac{db}{dt}$ when $h = 6$

Area is 24, so the base is:

$A = bh$

$24 = 6b$

$b = \frac{24}{6} = 4$

Then

$\frac{dA}{dt} = b\frac{dh}{dt} + h\frac{db}{dt}$

$-0.5 = 4(2) + 6\frac{db}{dt}$

$6\frac{db}{dt} = -8.5$

$\frac{db}{dt} = -\frac{8.5}{6}$

$\frac{db}{dt} = -1.4167$

The base of the triangle is decreasing at a rate of 1.4167 inch/hour.

ABC has vertices A(–3, –4), B(1, 5), and C(4,1). ABC is translated so that B’ is located at point (–3, 2). State the coordinates

koban [17]

If B went from (1, 5) to (-3, 2), that means it was shifted down 4 units and left 3 units. So for each of the other points, we subtract 4 from the x value, and subtract 3 from the y value. Point A is (-3, -4), moving this by subtracting 4 from x and 3 from y, we get A'(-7, -7). Point C was (4, 1), subtract 4 and 3, leaving C'(0, -2).
So A'(-3, -4), B'(-3, 2) and C'(0, -2)

Banu is 20 years older than binu. In 5 years, Banu will be twice as old as binu. Find their present age.

Katarina [22]

Answer:

i think Banu is 40 and Binu is 20

Step-by-step explanation:

if Banu was 35 and Binu was 15, 5 years go by Banu is 40 so still 20 years older and Binu is 20, Binu is half the age of Banu.
