4 x 10" = 4,000,000
n =
9514 1404 393
Answer:
n = 6
Step-by-step explanation:
Perhaps you want n for ...
[tex]4\times10^n=4\,000\,000\\\\10^n=1\,000\,000 \qquad\text{divide by 4}\\\\n=6\qquad\text{count the zeros}[/tex]
__
You know that multiplying by 10 appends a 0 to the right end of an integer number. So, a 1 with 6 zeros has been multiplied by 10 six times. The exponent signifies the number of times the factor is repeated. The exponent, n, is 6.

The points (0, 2), (1, 3), (2, 6), and (3, 11) are on the graph of a function. Which of the following equations represents that function?
A. h(x) = 0.5x^2 +1.5
B. h(x) = x + 2
C. h(x) = x^2 + 2
D. h(x) = 2x^2
Answer:
C. h(x) = x^2 + 2Step-by-step explanation:
Try the points by substituting values of x and y

Which triangle has an obtuse angle?
Answer: I cant see that last answer but I think it would be that one
Step-by-step explanation:
(Redirected from Obtuse triangle) An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
Hope this helps if it did pls mark me brainiest
none of them
Step-by-step explanation:
an obtuse angle is called to an wngle which is more than 90° and less than 180°
none of these have such an angle

if f(x)=3, what is f(4)= ?
Answer:
12
Step-by-step explanation:
Since f(x) = 3, you would multiply 3 by 4. This is because you are basically saying that you have 4 x's and each x is equal to 3. 3+3+3+3=12 or 4(3)=12

Find the following arc measures.
Answer:
Arc KL [tex]=23[/tex]
Arc OM [tex]=113[/tex]
Step-by-step explanation:
We know that Angle NPM is equal to 90 degrees.
Therefore, Angle KPM is also equal to 90 degrees.
We are told that Arc LM is equal to 67.
Thus, the measure for Arc KL is equal to [tex]90-67=23[/tex]
We also know that Angle OPN is equal to Angle KPL.
Therefore, the measure of Arc ON[tex]=23[/tex]
Using that information, we know that Arc OM is equal to [tex]90+23=113[/tex]
Hope I helped!
.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)
Answer:
45 g de oxido de hierro (III) liberarán 18.9 L de CO₂
Step-by-step explanation:
La reaccion quimica es la siguiente:
Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g)
1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.
Pasamos la masa de F₂O₃ a moles:
159.6 g . 1 mol /159.7g = 1 mol de oxido
Entonces, aplicamos la regla de tres:
1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.
Ahora calculamos los nuevos moles:
45g . 1 mol /159.7 g = 0.282 moles
Aplicamos la regla de tres:
Si un mol de oxido produce 3 moles de CO₂
0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂
Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:
Si 3 moles de CO₂ ocupan 67.2 litros
0.845 moles ocuparan (0.845 . 67.2/ 3 ) = 18.9 litros

Ross and Ronnie are late for their favorite show . Ross walks around a rectangular park with dimensions of 150 ft by 215 ft. Ronnie decides to cut across the park in a diagonal path. Who walks the shortest distance and by how much? *
Answer:
Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft
Step-by-step explanation:
The image attached represent the rectangular park. In this case, the dimensions are;
AB = CD = 215 ft
AC = BD = 150 ft
Total distance walked by Ross = AB + BD = 215 + 150 = 365 ft
Distance walked by Ronnie = AD
∠ABD = right angle triangle, using pythagoras rules;
AD² = AB² + BD²
AD² = 215² + 150²
AD² = 68725
AD = √68725
AD = 262.15 ft
Distance walked by Ronnie = 262.15 ft
Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft

Tara earns $8.00 per hour for babysitting. Which expression represents how much Tara earns for h hours of babysitting? 4 83
Answer:
Total amount Tara earned for babysitting for h hours = 8h
Step-by-step explanation:
Amount earned per hour for babysitting = $8.00
Number of hours of babysitting = h hours
Total amount Tara earned for babysitting for h hours =
Amount earned per hour for babysitting × Number of hours of babysitting
= 8 × h
= 8h
Total amount Tara earned for babysitting for h hours = 8h

A TV that usually sells for $180.18 is on sale for 15% off. If sales tax on the TV is 5%, what is the price of the TV, including
tax?
A. $162.34
B. $214.86
C. $160.81
D. $159.28
Answer:
C, $160.81
Step-by-step explanation:
180.18 decrease 15% =
180.18 × (1 - 15%) = 180.18 × (1 - 0.15) = 153.153
153.153 increase 5% =
153.153 × (1 + 5%) = 153.153 × (1 + 0.05) = 160.81065
