Use Euler's Formula to find the missing number. Faces: 20 Edges: 30 Vertices:

adoni [48]

Answer:

V=12

Step-by-step explanation:

Faces: 20 Edges: 30

Write the Euler's formula for 3-dimensional figures

F+V=E+2

Substitute some variables for their known values

20+V=30+2

Add the numbers on the right side of the equation

20+v=32

Subtract 20 on both sides

20-20+V=32-20

Subtract

V=32-20

Number of Vertices

V=12

Find the value of x. Round the length to the nearest tenth.

Mamont248 [21]

From right triangle trigonometry, we have the following:

$\displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side }$ ,

where the "opposite side" means the opposite side to angle with measure $35^o$ , and "adjacent side" means the adjacent side to angle with measure $35^o$ .

$tan(35^o)$ is a constant which can be found using a calculator.

In the calculator of the pc press: view - scientific - 35 - tan.

This gives $tan(35^o)=0.7$

Thus, back in the equation $\displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side }$ we substitute as follows and solve:

$\displaystyle{0.7= \frac{x }{12 }\\\\$

$x=0.7\cdot12=8.4$

Answer:

C. It would be shifted up.

Step-by-step explanation:

We base it off the y-intercept. Since -7 is less than 1, and our new function has a positive y-intercept, it would indeed be shifted up.

I am joyous to assist you anytime.
