Evaluate f(2) for the function f(x) = 3x² + 2x - 5.
Softa [21]

Answer:

f(2)= 11

Step-by-step explanation:

you have to substitute 2 for every x you see:

                       f(x) = 3x² + 2x - 5

                       f(2)= 3(2)^2+2(2)-5

                       f(2)= 11

A can of tuna has a volume 18pi cm3 and a height of 2 cm. Find the area of the label that wraps around the entire can and does n
Sphinxa [80]

Answer:

The area of the label is 12\pi\ cm^{2}

Step-by-step explanation:

step 1

Find the radius

we know that

The volume of the cylinder (can of tuna) is equal to

V=\pi r^{2} h

In this problem we have

V=18\pi\ cm^{3}

h=2\ cm

substitute and solve for r

18\pi=\pi r^{2} (2)

Simplify

18=r^{2}(2)

r^{2}=9

r=3\ cm

step 2

<em>Find the lateral area of the can</em>

The lateral area of the cylinder (can of tuna) is equal to

LA=2\pi rh

we have

r=3\ cm

h=2\ cm

LA=2\pi (3)(2)=12\pi\ cm^{2}

A candy store called "Sugar" built a giant sugar cube out of wood to hang above the entrance to their store. It took 545454 feet
DedPeter [7]

Answer:

<em>The volume inside the giant sugar cube is 27 cubic feet.</em>

Step-by-step explanation:

It took 54 feet² of material to build the giant sugar cube. That means, the total surface area of the cube is 54 feet²

<u>Formula for surface area of a cube</u> is:  S= 6a^2 , where a is the length of each edge of the cube.

So, we will get.........

6a^2=54\\ \\ a^2= \frac{54}{6}=9 \\ \\a= \sqrt{9}= 3

Now, <u>the volume of the cube will be</u>:  V= a^3= (3)^3 = 27 feet³

Thus, the volume inside the giant sugar cube is 27 cubic feet.

If one zero of the quadratic polynomial x²+3x+k is 2, then the value of k is. [ ]
Alex_Xolod [135]

Answer:

b) -10

Step-by-step explanation:

x^2 + 3x + k = (x - 2)(x - a)

(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a

-2 - a = 3

2a = k

a = -5

k = 2(-5) = -10

Answer: b) -10
