Answer:

-.82

Step-by-step explanation:

To find the average rate of change over an interval, you use rise over run with the first point and the last point (in this case, the first point is (50, 35.8) and the last point is (60, 27.6)). This will give you an average rate of change of -.82.

In the context of this problem, -.82 is how much your expected remaining life span decreases each year.

The volume of the rectangular prism is 648 feet. The rectangular base is 6 feet by 9 feet. What is the height of the prism?
IrinaK [193]

Answer:

h=12ft

Step-by-step explanation:

The formula one would use for finding the volume of a rectangular prism is as follows:

  • Volume = length × width × height , V=l*w*h

With this in mind, let's plug in the given variables in the question for this formula.

V=648ft^3

l=6ft

w=9ft

h= ?

  • We don't know the height, but that's just fine. We will plug in all our values and isolate h.

V=lwh\\648ft^3=(6ft)(9ft)h

  • I'm leaving in units just because I want to show that units aren't just for show. They can be used when in doubt of how to go about your math.

648ft^3=(6ft)(9ft)h\\648ft^3=(54ft^2)h\\\frac{648ft^3}{54ft^2}=\frac{(54ft^2)h}{54ft^2}

  • Notice, that the units on the left side cancel out, leaving only the unit ft left next to the solution. In the same way, the units on the right side cancel out too, leaving only h, height.

\frac{648ft^3}{54ft^2}=\frac{(54ft^2)h}{54ft^2}\\12ft=h

If involving units only confuses you, like it does for me, you can remove them like so, you just need to know what units your solution uses instead of being able to come to the proper units by using math.

V=lwh\\648=(6)(9)h\\648=54h\\\frac{648}{54}=\frac{54h}{54}\\12ft=h

Answer:

x = 42

Step-by-step explanation:

The angle between the tangent and the secant is

\frac{1}{2} difference of the measure of the intercepted arcs, that is

x = 0.5( 136 - 52) = 0.5 × 84 = 42

The value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after
WARRIOR [948]
General exponential equation
y = A(1+r)^x
where
A = initial value
r = rate increase (+) or decrease (-)
x = time period of the change
y = projected value

y = 300(1.05)^x
in this problem, x = years after 2017
we want to find an x that makes the value more than or equal to 650

650 <= 300(1.05)^x

Use the diagram to answer the following questions.125°Lx2X+10NmZNPMdegreesmZLPMdegrees
lutik1710 [3]

For the angle MPN we know that is oposite to the angle QPL so the will be equal so:

\angle MPN=125º

Now with the value of MPN we can made an equation for x so:

125=2x+10

and we solve for x

\begin{gathered} 125-10=2x \\ \frac{115}{2}=x \\ 57.5=x \end{gathered}

and the angle LPM will be the complementari angle of 125 so:

\begin{gathered} \angle LPM=180-125 \\ \angle LPM=55º \end{gathered}
