How does ((x) = 4 • 6^x change over the interval from x=2 to x=3
Answers
Answer:
f(x) increases by a factor of 6
Step-by-step explanation:
[tex]f(x) = 4 *6^x[/tex]
[tex]f(2) = 4 *6^2[/tex]
[tex]f(2) = 4 *36[/tex]
[tex]f(2) = 144[/tex]
[tex]f(x) = 4 *6^x[/tex]
[tex]f(3) = 4 *6^3[/tex]
[tex]f(3) = 4 *216[/tex]
[tex]f(3) = 864[/tex]
f(x) increases by a factor of 6
144 * 6 = 864

46 degrees
74 degrees
81 degrees
99 degrees
Answers
Answer:
81°
Step-by-step explanation:
m(arc)JKL = 2m<E = 2(99°) = 198°
m(arc)JEL = 360° - m(arc)JKL
m(arc)JEL = 360° - 198° = 162°
m<K = (1/2)m(arc)JEL = 162°/2 = 81°

All spreadsheets have probability functions built in. Many graphing calculators are similarly capable of giving area from probability, or probability from area. A TI-84 requires two limits. In most cases, an upper limit of about 10 standard deviations from the mean (here, 3000 kWh) will work just fine. It tells me ...

12.9 m
Step-by-step explanation:
Let length = 3x, then breadth is 2x
if breadth is 8.6 m, so 2x = 8.6 m, x = 8.6/2 = 4.3 m
length = 3x = 3* 4.3 = 12.9 m
