Problem 10
Answer: approximately 57.39159 kmExplanation: You'll use the equation cos(28) = d/65 to solve for d to get d = 65*cos(28) = 57.39159 approximately. We use the cosine ratio because it ties together the adjacent and hypotenuse.
=====================================
Problem 11
Answer: approximately 10.46162 metersExplanation: This time we use the sine rule. We have the height as the opposite side (which is unknown, call it x) and the hypotenuse is the ladders length (11). So we have sin(72) = x/11 which solves to x = 11*sin(72) = 10.46162
=====================================
Problem 12
Answer: approximately 16.05724 cmExplanation: Now we use the tangent rule to connect the opposite and adjacent sides.
tan(37) = 12.1/x
x*tan(37) = 12.1
x = 12.1/tan(37)
x = 16.05724 approximately
solve the equation -16=a- 19
Answer:
a = 3
Step-by-step explanation:
Collect like-terms:
\( - 16 = a - 19\)
\(a = - 16 + 19\)
\(a = 3\)
Answer: 3
Step-by-step explanation: you take 19 from 3 giving you -16
The half-life of caffeine in the human body is about 6.4 hours. cup of coffee has about 80 mg of caffeine: Write an equation for the amount of caffeine in person $ body after drinking cup of coffee? Let € be the milligrams of caffeine in the body after hours. How much caffeine wIll remain after 10 hours? mg How long until there are only 20 mg remaining? hours
Thus, the time taken to drop the caffeine from 80 mg to 60 mg is 2.46 hours.
Explain about the Exponential equation:Calculating the exponential growth as well as decay of a given collection of data is done using an exponential function, which is a mathematical function.
Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread. An exponential function has the following form at its most fundamental level.
f(x) = \(a^{x}\)
Exponential equation for the amount of Caffeine
C = 80\((2)^{-t/6}\)
Amount of caffeine C = 60 mg.
60 = 80\((2)^{-t/6}\)
3/4 = \((2)^{-t/6}\)
Taking log on both sise:
\(log_{2}(3/4) = -t/6\)
Solve the log function using the log calculator:
-t/6 = (-0.41)
t = 0.41 * 6
t = 2.46 hours
Thus, the time taken to drop the caffeine from 80 mg to 60 mg is 2.46 hours.

If Daniela graphed the function describing Mondays storm she would find that it is
Daniela's graph of the function describing Monday's storm depicted the storm's temporal evolution, showcasing the changing intensity of rainfall, intermittent spikes, shifting wind direction, and overall duration. Analyzing the graph allowed Daniela to gain insights into the storm's behavior and better understand its impact on the area.
Daniela graphed the function describing Monday's storm and observed several key features. The graph displayed a rapid increase in precipitation during the early morning hours, with rain intensifying steadily until reaching its peak around midday. Afterward, the precipitation gradually subsided, leading to a decline in rainfall amounts throughout the afternoon and evening.
The graph exhibited a distinct pattern of fluctuation, reflecting the storm's dynamic nature. Intermittent spikes in rainfall were visible, indicating periodic bursts of heavy precipitation throughout the day. These spikes were followed by brief periods of relative calm, during which the rainfall decreased temporarily before resuming its intensity.
Furthermore, Daniela noticed a gradual shift in wind direction as the storm progressed. Initially, the wind blew from the east, but it gradually veered towards the south as the storm system moved across the region. The change in wind direction was evident on the graph, showing a gradual rotation of the wind vector over time.
The graph also revealed the storm's duration, spanning from the early morning hours until late evening. The rainfall accumulation steadily increased during the storm's initial phase and reached a maximum before gradually tapering off towards the end of the day.

Find the following trigonometric Fourier Series:
(a) Extend the definition of f(x) to make it an even function f*(x),
\(f^*(x)=\begin{cases}0&\text{if }-2\le x<-1\\1&\text{if }0\le x\le1\\0&\text{if }1<x\le2\end{cases}\)
and we take f* to be periodic over an interval of length P = 4. We compute the coefficients of the cosine series:
\(a_n = \displaystyle\frac2P \int_{-2}^2 f^*(x)\cos\left(\frac{2n\pi}Px\right)\,\mathrm dx = \frac{2\sin\left(\frac{n\pi}2\right)}{n\pi}\)
Note that a₀ = 1 (you can compute the integral again without the cosine, or just take the limit as n -> 0). For all other even integers n, the numerator vanishes, so we split off the odd case for n = 2k - 1 :
\(a_{2k-1} = \dfrac{2\sin\left(\frac{(2k-1)\pi}2\right)}{(2k-1)\pi}\)
Then the cosine series of f(x) is
\(\displaystyle \frac{a_0}2 + \sum_{k=1}^\infty a_{2k-1}\cos\left(\frac{(2k-1)\pi}2x\right)\)
(b) For the sine series, you instead extend f(x) to an odd function f*(x),
\(f^*(x)=\begin{cases}-1&\text{if }-2\le x\le-1\\x&\text{if }-1<x<1\\1&\text{if }1\le x\le2\end{cases}\)
Again, P = 4, and the coefficient of the sine series are given by
\(b_n = \displaystyle\frac2P\int_{-2}^2f^*(x)\sin\left(\frac{2n\pi}Px\right)\,\mathrm dx\)
which we can again split into the even/odd cases,
\(b_{2k} = -\dfrac1{k\pi}\)
\(b_{2k-1} = \dfrac{4(-1)^{k+1}+2(2k-1)\pi}{(2k-1)^2\pi^2}\)
So the sine series is
\(\displaystyle \sum_{k=1}^\infty\left(b_{2k}\sin\left(k\pi x\right) + b_{2k-1}\sin\left(\frac{(2k-1)\pi}2x\right)\right)\)
I've attached plots of the extended versions of f(x) along with the corresponding series up to degree 4.
Evaluate the definite integral of sin^5(x)dx from 0 to pi/2.
Step-by-step explanation:
The definite integral of sin^5(x)dx from 0 to pi/2 can be evaluated using the method of substitution.
Let u = sin(x), then du = cos(x)dx
The integral becomes:
∫sin^5(x)dx = ∫u^5du from 0 to sin(π/2)
= (u^6)/6 evaluated at sin(π/2) and 0
= (sin^6(π/2))/6 - 0
= (1^6)/6
= 1/6
So, the definite integral of sin^5(x)dx from 0 to pi/2 is equal to 1/6.

What are the points scored in a basketball?In basketball, players can score 1, 2, 3 (or even 4 or 5 points) during a possession.
Players who score five points are fouled in the act of shooting a three-pointer and making the shot.
Players who score four points attempt a three-pointer and make the subsequent foul shot.
Players who score three points go beyond the 3-point line, in bounds.
Players who score two points go inside the 3-point line, in bounds.
Players who score one point make free throws.

Step-by-step explanation:
When x equals 0, that means a is going to be multiplied by 1 since any number to the power of 0 is 1, so \(f(0)=a=9\). When x equals 1, that means that \(f(1) = 9b=15\), so \(b=\frac{15}{9} =\frac{5}{3}\). This means that the equation should be \(f(x)=9*\frac{5}{3}^x\).

If someone answers this and shows work I will give Brainlyest
Answer:
x = 2
y = 1
Step-by-step explanation:
-2x-3y=-7, y=6x-11
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-2x - 18x = -40
-20x = -40
x = 2
y = 6(2) - 11
y = 12 - 11
y = 1
Answer:
x = 2, y = 1
Step-by-step explanation:
We have a system of equations:
-2x - 3y = -7
y = 6x - 11
Substitute the given value of y into the equation -2x - 3y = -7
-2x - 3 * (6x - 11) = -7
-20x = -7 - 33
-20x = - 40
x = 2
Substitute the given value of x into the equation y = 6x - 11
y = 6x - 11
y = 6 * 2 - 11
y = 1

To determine the equation governing the inequality line, enter your slope and a point into the formula y = mx + B, where "m" denotes the slope, "x, y" denotes a point on the line, and "b" is the y-intercept. By inserting (0, 0), you get 0 = 0 + b, which equals 0.
