Find y. B C Зу A 8 D м 2 4 15 10

Mathematics

Answer:

y=4

Step-by-step explanation:

The question is asking what is the value of y:

Since all lengths have a dash on them they are all equal :

So 3y = y+8

3y = y + 8

First we subtract y from both sides:

3y-y = y+8-y

2y = 8

Divide both sides by 2:

2y÷2 = 8÷2

y = 4

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about the
insens350 [35]

Answer:

So, the volume V is

V=\frac{14\pi}{3}

Step-by-step explanation:

We have that:

y=7x\\\\y=0\\\\x=1\\\\x=-4\\

We have the formula:

V=2\pi\int_a^b x(g(x)-f(x))\, dx\\\\g(x)>f(x).

We calculate the volume V, we get

V=2\pi\int_a^b x(g(x)-f(x))\, dx\\\\V=2\pi\int_0^1 x(7x-0)\, dx\\\\V=2\pi\int_0^1 7x^2\, dx\\\\V=2\pi\cdot 7\left[\frac{x^3}{3}\right]_0^1\\\\V=14\pi\left(\frac{1}{3}-\frac{0}{3}\right)\\\\V=\frac{14\pi}{3}

So, the volume V is

V=\frac{14\pi}{3}

We use software to draw the graph.

For each function shown:
yaroslaw [1]

Answer:

Step-by-step explanation:

Function (1) has been given as,

y = 0.5 + 3x

Table for the points on this function,

x        0         1          2          3         4

y       0.5     3.5       6.5      9.5     12.5

y_2-y_1=3.5-0.5=3

y_3-y_2=6.5-3.5=3

There is a common difference of 3 each successive term of y from the previous term.

Therefore, starting point of the function is (0, 0.5)

There is a linear growth of 3 with the increase in the value of x.

Function (2),

y = 3(0.5)ˣ

x       0         1          2           3           4

y       3        1.5     0.75     0.375   0.1875

Starting point of the function will be (0, 3)

There is a common ratio of 0.5 in each successive term to the previous term.

\frac{y_2}{y_1}=\frac{1.5}{3}=0.5

\frac{y_3}{y_2}=\frac{0.75}{1.5}=0.5

Function (2) increases exponentially with a common ratio of (0.5) with the increase in x.

allochka39001 [22]

Answer:

14

Step-by-step explanation:

f(-2)=3*(-2)-2/-2-2=-8/-4=2

f(-1)=3*(-1)-2/-1-2=-5/-3=5/3

f(0)=3*0-2/0-2=-2/-2=1

2+1+5/3=6+3+5=14
