what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i
nekit [7.7K]

Answer:

a = 3

Step-by-step explanation:

To determine the value of a, we want b^x to be 1, so that f(x) = a \times 1. Notice that if x = 0, then f(0) = a \times (b^0) = a, so the value of a is simply f(0). From the graph, it appears that f(0) = 3, so therefore a = 3.

The population of kansas city, missouri was 435,000 in 1990 and 482,300 in 2005. if the population is changing linearly, write a
Jlenok [28]
Find the slope of the line connecting (1990,435000) and (2005,482300):

        482300-435000        47300
m = ----------------------- = ---------------- = 3153/yr (approx)
          2005 - 1990                15 yr

Use the point-slope formula to find the equation of this str. line:

y-435000 = (3153/yr)(x-1990)

The year 2020 is 30 years after 1990.  Thus, the expected pop in 2020 is

given by     y-435000 = 3153(30) = 94590, so that y = 529590.

Given m 1= 65, find the measure of each missing angle.Givd your reasoning
lorasvet [3.4K]

Answer:

Step-by-step explanation:

Given:

m∠1 = 65°

Since. ∠1 and ∠2 are the angles of linear pair,

m∠1 + m∠2 = 180°

65° + m∠2 = 180°

m∠2 = 115°

m∠1 = m∠3 [Vertical angles]

m∠3 = 115°

Since, ∠1 and ∠4 is the linear pair of angles,

m∠1 + m∠4 = 180°

65° + m∠4 = 180°

m∠4 = 180 - 65 = 115°

m∠4 + m∠5 = 180° [Consecutive interior angles between the parallel lines]

115° + m∠5 = 180°

m∠5 = 180° - 115° = 65°

m∠5 + m∠6 = 180° [Linear pair of angles]

65° + m∠6 = 180°

m∠6 = 115°

m∠5 = m∠7 [Vertical angles]

m∠5 = m∠7 = 65°

m∠6 = m∠8 [Vertical angles]

m∠6 = m∠8 = 115°
