Help me with question 4 and 5

Mathematics

Answer:

2.6768·10^(-14)  (Answer C)

Step-by-step explanation:

Problem 4:  We ADD the powers of 10:  10^6·10^(-3) = 10^3.  Also, 3.6·1.7 = 6.12.  Therefore, Answer D is correct.

Problem 5:  Again we ADD (combine) the powers of 10:  10^(-10)·10^(-5) =

10^(-15).  4.78·5.6 = 26.768.  Our intermediary answer is thus:

26.768·10^(-15).  This must be rewritten in the form x.xxxx, so here we have:

2.6768·10^(-14)  (Answer C)

Given the following exponential function, what is the initial amount y 60(1.71)^x?
Aleks [24]

Answer:

60

Step-by-step explanation:

The initial y value can be found by setting x to 0. Anything to the power of 0 is 1, so 1.71^x when x is 0 is just 1. 60*1=60, which is the initial y value. Hope this helps!

Write the equation of the line that passes thriugh the points (3,-2) and (5,-9)?
Tanya [424]

Answer:

y = -7/2x + 17/2

Step-by-step explanation:

Slope = (-9 - - 2)/(5 - 3)

= -7/2

y-intercept: -2 - (-7/2)(3)

= -2 + 21/2 (-2*2+21)/2

= 17/2
