how do i solve –1.8c + 5.1d for c = 2.9 and d = -4.2.
Answer:
See below
Step-by-step explanation:
-1.8c + 5.1d plug the numbers in that you were given.
-1.8(2.9) + 5.1(-4.2)
Multiply the first and second group of numbers
-1.8 x 2.9 = - 5.22
5.1 x -4.2 = - 21.42
Now add the two numbers together but remember they are both negative numbers. So when you add them together, it will end up being a more negative number.
-5.22 + -21.42 = - 26.64

A rocket was launched into the air from a podium 6 feet off the ground. The rocket path is represented by the equation h(t)=-16t2+120t +6, where h(t) represents the height, in feet, and t is the time, in seconds. Find the average rate of change from the initial launch to the maximum height.
Answer:
60
Step-by-step explanation:
The given function is:
The average rate of change of h(t) from t=a to t=b is given by:
We can rewrite this function as:
The maximum height of the rocket is 231 and it occurs at t=3.75
The initial launch occurs at: t=0
and
The average rate of change from the initial launch to the maximum height is
The average rate of change from the initial launch to the maximum height is 59.21 ft/s.
We have a equation that represents the Rocket path.
We have to find the average rate of change from the initial launch to the maximum height.
What do you mean by a Time - varying quantity ?A time varying quantity is the quantity whose absolute value change with time. For example - y = f(t) = 2t - 1 , where y is the displacement and it varies as y = 2t - 1 with time.
According to the question, we have -
Equation → [tex]h(t) = -16t^{2} +120t+6[/tex]
Height of podium → 6 feet.
Initial velocity (u) = 0
Now -
[tex]h(t) = - 16t^{2} +120t+6[/tex]
Differentiating w.r.t time, we get →
[tex]$\frac{dh}{dt} = - 32t + 120[/tex]
For maximum height → [tex]$\frac{dh}{dt} = 0[/tex]
-32t + 120 = 0
32t = 120
t = 3.8 seconds
This means that at t = 3.8 seconds the rocket will reach its maximum height. Therefore, the maximum height will be -
h(t) = - 16 x 3.8 x 3.8 + 120 x 3.8 + 6
h(t) = - 231.04 + 456 + 6
h(t) = 224.96 + 6
h(t) = 230.96 = 231
The maximum height reached by the rocket is 231 feet's.
Now -
Initial height = 6 feet
Initial time = 0 s
Final height (max) = 231
Time at maximum height = 3.8
Therefore, the average rate of change from the initial launch to the maximum height will be -
[tex]$v_{avg} = \frac{231-6}{3.8-0}=59.21[/tex]
v (avg) = 59.21 ft/s
Hence, the average rate of change from the initial launch to the maximum height is 59.21 ft/s

A cone-shaped container is completely filled with liquid. The container has a radius of 60 cm and an height of 210 cm. The liquid is drained from the container at a rate of 1099 cm³ per hour. How many hours will it take to drain all of the liquid? Use 3. 14 to approximate pi. Enter your answer in the box. Hours.
Find the volume of the cylinder to know how much liquid is in it:
volume of a cylinder = Pi x r^2 x height.
Volume = 3.14 x 60^2 x 210
Volume = 2,373,840 cubic cm
now to find the length of time divide total cubic cm by the drainage rate:
2,373,840 / 1099 = 2,160 hours
Answer: 2,160 hours

O (f.g)(x) = 6x2 + 7
O (fºg)(x) = 6x2 + 23x + 7
O(fºg)(x) = 5x + 8
Answer:
3rd option
Step-by-step explanation:
(f • g)(x)
= f(x) × g(x)
= (3x + 1)(2x + 7)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(2x + 7) + 1(2x + 7) ← distribute parenthesis
= 6x² + 21x + 2x + 7 ← collect like terms
= 6x² + 23x + 7
Mr. Appleman own a rectangle apple orchard that measure 18m long and has a diagonal length of 25m. What is the width of his Orchard to the nearest the tenth of a metre?
Answer:
length = 17.3 m
Step-by-step explanation:
Rectangles have four right angles, so the diagonal and its sides will form a right triangle. This allows us to use the Pythagorean Theorem to find the length.
l^2 + 18^2 = 25^2
sqrt l^2 = sqrt (25^2 - 18^2), where l = 17.349 = 17.3 m

Research done in the mid 1980s indicated that 80% of grizzly bears in the greater ecosystem of Yellowstone National Park entered their den for hibernation by the last day of November. This has come into question as of late. Researchers have hypothesized that climate change has postponed bears entering hibernation until later in the season; that is, researchers believe that a smaller percentage of bears are entering their den for hibernation by the last day of November. Sixty-two Yellowstone grizzly bears were tracked via radio monitors, which allow scientists to pinpoint when the bears enter their dens with a high degree of accuracy. Of the sixty-two Yellowstone grizzly bears being tracked, forty-two entered their den for hibernation by the last day of November.

Line m passes through point (-2,-1) and is perpendicular to the graph of y=-2/3x+6. Line n is parallel to line m and passes through the point (4,-3). What is the equation in slope-intercept form of line n?
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
[tex]y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{3}} x+6\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]
well, we know that "m" is perpendicular to the line above, so that means that line "m" has a slope of
[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{-\cfrac{2}{3}} ~\hfill \stackrel{reciprocal}{-\cfrac{3}{2}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{3}{-2}\implies \cfrac{3}{2}}}[/tex]
keeping in mind that parallel lines have exactly the same slope, and since we know that "n" is parallel with "m", that means that if "m" has a slope of 3/2 than "n" must have the same slope.
so we're really looking for the equation of a line whose slope is 3/2 and passes through (4 , -3)
[tex](\stackrel{x_1}{4}~,~\stackrel{y_1}{-3})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{3}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-3)}=\stackrel{m}{\cfrac{3}{2}}(x-\stackrel{x_1}{4}) \\\\\\ y+3=\cfrac{3}{2}x-6\implies y=\cfrac{3}{2}x-9[/tex]
