3. f(-6) = 12+1 =13

f(-2) = 4+1 = 5

f(0) =1

Range {1,5,13}

4. f(-2) = (-2)^3+1 =-7

f(-1) = (-1)^2 +1 =0

f(3) = (3)^3 +1 = 28

Range = {-7,0,28}

5.the sequence is arithmetic

d= -11+19 = 8

an = a1 + d(n-1)

an = -19 +8(n-1)

6.l =w+5

a =l*w

a(w) =(w+5) * w

a(w)= w^2 +5w

f(w) = w^2 +5w

f(8) = 8^2 +5(8)

f(8) = 64 +40

f(8) =104 in^2

Bo Karah can run a race in 4 hours 33 minutes if he runs at 7 m/s. How long will it take in hours and minutes if

lidiya [134]

Answer:

7 hours and 9 minutes

Step-by-step explanation:

4 hours and 33 minutes is 273 minutes

7 m/s —> 273 minutes

11 m/s —> M

Criss cross to get M

11x273= 7M

3003=7M

M=429 minutes

==> 429 minutes is 7 hours and 9 minutes

Volume of composite figures

ollegr [7]

Given:

The diameter of cylinder is 6 in and the height of the cylinder is 8 in.

The dimensions of the cuboid are 15 in by 9 in by 9 in.

To find:

The volume of the composite figure.

Solution:

Volume of a cuboid is:

$V_1=length\times breadth\times height$

$V_1=15\times 9\times 9$

$V_1=1215$

So, the volume of the cuboid is 1215 cubic inches.

The diameter of cylinder is 6 in. So, the radius of the cylinder is:

$\dfrac{6}{2}=3\text{ inches}$

Volume of a cylinder is:

$V_2=\pi r^2h$

Where, r is the radius and h is the height.

Substituting $r=3,h=8,\pi =3.14$ , we get

$V_2=(3.14)(3)^2(8)$

$V_2=(3.14)(9)(8)$

$V_2=226.08$

The volume of the cylinder is 226.08 cubic inches.

Now, the volume of the composite figure is:

$V=V_1+V_2$

$V=1215+226.08$

$V=1441.08$

Therefore, the volume of the composite figure is 1441.08 cubic inches.
