Answer:

13.7 mm

220cm

863.6

0.02 km

29000m

Step-by-step explanation:

Cm = 10mm, so 1.37 cm = 13.7 mm.

m = 100cm, so 2.20 m = 220cm.

in = 25.4 mm, so 34in = 863.6

m = 0.001 km, so 20m = 0.02 km.

km = 1000 m, so 29km = 29000m.

Answer:

  1. 370
  2. 2000
  3. 863.6
  4. 0.02
  5. 29000

Step-by-step explanation:

  • <em>1 cm = 10 mm</em>
  • <em>1 m = 100 cm</em>
  • <em>1 in = 25.4 mm</em>
  • <em>1 m = 0.001 km</em>
  • <em>1 km = 1000 m</em>

1. Use proportions and cross-multiply:

<em></em>\frac{X mm }{37cm} =\frac{10 mm}{1cm} \\x = 37 * 10 = 370<em></em>

2. Use proportions and cross-multiply:

\frac{20 m}{X cm} =\frac{1 m}{100cm} \\x=20*100=2000

3. Use proportions and cross-multiply:

\frac{34in}{Xmm} =\frac{1in}{25.4mm} \\x=34*25.4=863.6

4. Use proportions and cross-multiply:

\frac{20m}{Xkm} =\frac{1m}{0.001km} \\x=20*0.001=0.02

5. Use proportions and cross-multiply:

\frac{29 km}{Xm}=\frac{1 km}{1000m} \\x=29*1000=29000

The function is defined by f(x)= x^2+3x-10
yaroslaw [1]
First you put (x+5) into the initial function wherever you see x so it becomes
(x+5)^2+3(x+5)-10=x^2+kx+30
(x^2+5x+25)+(3x+15)-10 simplified left side
x^2+8x+30 fully simplified left side 
thus k=8
x^2+8x+30=0 to find 0s
-4 + 3.7416573867739i
<span>-4 - 3.7416573867739i
</span>these are the roots you find after using the quadratic formula 
the second one is the smallest

B) y = log2 (4" - 4)<br> find the inverse of this equation
GuDViN [60]

Answer:

y =  \frac{1}{4}  \times  {2}^{x}  - 1

Step-by-step explanation:

Assuming the given logarithmic equation is

y =   \log_{2}( {4}{x }  - 4)

We interchange x and y to get:

x=   \log_{2}( {4}{y} - 4)

We solve for y now:

{2}^{x}  =  {4}{y}   - 4

We add 4 to both sides to get;

{2}^{x}  + 4 = 4y

Divide through by 4:

y =  \frac{1}{4}  \times  {2}^{x}  - 1

5. (9r 3 + 5r 2 + 11r) + (-2r 3 + 9r - 8r 2)
ad-work [718]

Answer:

7r³ - 3r² + 20r

Step-by-step explanation:

(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)

You can get rid of the parentheses since there is nothing to distribute.

9r³ + 5r² + 11r - 2r³ + 9r - 8r²

Combine like factors.

7r³ - 3r² + 20r
