What is the value of y when x = 0?
Answer:
y= -7
Step-by-step explanation:
y=ax+b
Find a where a=y2-y1 /x2-x1
y2=13,y1=5 x2=5,x1=3
substituting the values
a=13-5/5-2
a=8/2
a=4
substituting a into the formular
y=4x+b
taking x and y values let say 3 and 5 for x and y
the equation becomes
5=4(3)+b
5=12+b
5-12=b
-7=b
substituting the values of a and b into the equation
y=4x-7
when x=0
y=4(0)-7
y=0-7
y=-7
so when x=0,y=-7
Decompose 3p-1/p^2-1 into partial functions
(please select from the choices)
Answer:
a)
Step-by-step explanation:
[tex]\dfrac{3p-1}{p^2-1}[/tex]
Factorize the denominator:
[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}[/tex]
Therefore,
[tex]\implies \dfrac{3p-1}{(p+1)(p-1)}=\dfrac{A}{p+1}+\dfrac{B}{p-1}[/tex]
[tex]\implies 3p-1=A(p-1)}+B(p+1)[/tex]
When p = 1:

[tex]\implies B=1[/tex]
When p = -1:
[tex]\implies -4=A(-2)}+B(0)[/tex]
[tex]\implies A=2[/tex]
Therefore,

Selected values of g(t) are given in the table above. a. Using the data in the table, approximate g'(3). Using correct units, interpret the meaning of g'(3) in the context of this problem. b.

Using the result from part (b), approximate the amount of unspoiled grain remaining in the silo at time t = 8. d. Based on the model in part (c), is the amount of unspoiled grain in the silo increasing or decreasing at time t = 6? Show the work that leads to your answer. =
Hi there!
a)
We can approximate g'(3) by finding the slope of g(t) over an interval containing t = 3.
We can use the endpoints t = 1 and t = 5 min for the best estimate.
[tex]slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{20.5-15.1}{5-1} = \boxed{1.35 \frac{ft^3}{min^2}}[/tex]
This means that the rate of grain being added to the silo is INCREASING at a rate of 1.35 ft³/min². (Or in other words, the grain is being poured at an increasingly greater rate)
b)
The total amount of grain added is the integral of g(t), so:
[tex]\text{total amount of grain} = \int\limits^8_0 {g(t)} \, dt[/tex]
We can do a right riemann sum by using the right endpoints (t = 1, t = 5, t = 6, t = 8) to calculate.
Riemann sums are essentially rectangles added up to calculate an approximate value for the area under a curve.
The bases are the spaces between each value in the chart, while the heights are the values of g(t).
Using the intervals and values in the chart:
[tex]1(15.1) + 4(20.5) + 1(18.3) + 2(22.7) = \boxed{160.8 ft^3}[/tex]
c)
We can subtract the two integrals to find the total amount of unspoiled grain.
With g(t) being fresh grain and w(t) being spoiled grain, let y(t) represent unspoiled grain.
[tex]y(t) = \int\limits^8_0 {g(t)} \, dt - \int\limits^8_0 {w(t)} \, dt[/tex]
Use a calculator to evaluate:
[tex]y(t) = 160.8 - \int\limits^8_0 {w(t)} \, dt = 160.8 - 99.05 = \boxed{61.749 ft^3}[/tex]
d)
We can do the first derivative test to determine whether the amount of grain is increasing or decreasing. (Whether the first derivative is positive or negative at this value).
For the above integral, we know that the derivative is:
[tex]y'(t) = g(t) - w(t)[/tex]
Plug in the values for t = 6:
[tex]w(6) = 32 \cdot \sqrt{sin(\frac{\pi (6)}{74})} = 16.06[/tex]
[tex]y'(6) = g(6) - w(6) = 18.3 - 16.06 = 2.23 \frac{ft^3}{min}[/tex]
This value is POSITIVE, so the amount of unspoiled grain is INCREASING.

a glass fish tank in the shape of a rectangular prism has a base that measures 22 inches by 12 inches. If the tank can hold a maximum of 3,960 cubic inches of water, how much glass was used to construct the tank?
Answer:
582.76 square inches of glass is required to construct the tank.
Step-by-step explanation:
Base dimension = 22×12 inches
volume of fish tank =3960 cubic inches
volume= l×b×h
3960=22×12×h
h=3960/(22×12)
h=3960/462
h=8.57 inches
the glass used=lateral surface area of a rectangular prism
=2h(l+b)
=2×8.57(22+12)
=17.14(34)
=572.76square inches

To find the height of a pole, a surveyor moves 150 feet away from the base of the pole and then, with a transit 4 feet tall, measures the angle of elevation to the top of the pole to be 42°. To the nearest foot, what is the height of the pole?
Answer: The answer is 139 feet
H = height of the pole =?
BC = ED = height of the transit = 4 ft
CD = BE = distance moved away from the base of the pole = 140 ft
Consider the ΔABE
tan44 = AE/BE
tan44 = h/140
h = 140 tan44
h = 135.2 ft
H = height of pole = AE + ED = h + ED = 135.2 + 4
H = 139.2 ft
