Answer:
[tex]\sin(\theta)=\frac{\sqrt{13}}{7}\approx0.5151[/tex]
Step-by-step explanation:
So we know that Θ is acute and that:
[tex]\cos(\theta)=6/7[/tex]
First, note that since Θ is acute, it is between 0 and 90 degrees, meaning that all of our trig ratios will be positive since the angle is in the Quadrant I.
The Pythagorean Identity is:
[tex]\sin^2(\theta)+\cos^2(\theta)=1[/tex]
We know that cosine is 6/7. Substitute:
[tex]\sin^2(\theta)+(\frac{6}{7})^2=1[/tex]
Square:
[tex]\sin^2(\theta)+\frac{36}{49}=1[/tex]
Subtract both sides by 36/49. Change the 1 to 49/49 to make a common denominator:
[tex]\sin^2(\theta)=\frac{49}{49}-\frac{36}{49}[/tex]
Subtract:
[tex]\sin^2(\theta)=\frac{13}{49}[/tex]
Take the square root of both sides:
[tex]\sin(\theta)=\pm\sqrt{\frac{13}{49}}[/tex]
Simplify:
[tex]\sin(\theta)=\pm\frac{\sqrt{13}}{7}[/tex]
As mentioned previously, since Θ is acute, all of the trig functions must be positive. So, we can ignore our negative answer:
[tex]\sin(\theta)=\frac{\sqrt{13}}{7}\approx0.5151[/tex]
and we're done!

There are 75 students in a speech contest. Yesterday, 2/5 of them gave their speeches. Today, 1/3
of the remaining students gave their speeches. How many students still haven't given their speeches?
Work Shown:
2/5 of 75 = (2/5)*75 = 0.4*75 = 30
Yesterday 30 people gave speeches. There are 75-30 = 45 people left.
1/3 of 45 = (1/3)*45 = 15
Then another 15 people gave speeches today. So there are 45-15 = 30 people who haven't given their speeches yet.

find the measure of angle E
Answer:
E = 76°
Step-by-step explanation:
Exterior angle B = 116°
So ABC = 180° - 116°
= 64°
In triangle ABC , AC = BC ( given )
So angle BAC = angle ABC = 64° ( Opposite angle of two same sides of a triangle are equal )
According to Angle Sum Property of a Triangle ,
BAC + ABC + ACB = 180°
=> ACB + 64° + 64° = 180°
=> ACB = 180° - 128°
= 52°
Also , angle ACB = angle ECD = 52° ( Vertical Opposite Angles are equal )
In triangle ECD ,
EC = ED ( given )
So, angle ECD = angle EDC = 52° ( Opposite angle of two same sides of a triangle are equal )
According to Angle Sum Property of a Triangle ,
ECD + EDC + CED = 180°
=> 52° + 52° + CED = 180°
=> CED = 180° - 104°
= 76°

On Thursday, a local hamburger shop sold a combined total of 580 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Thursday?
Answer:
Hey there!
Let h be the number of hamburgers sold.
Let c be the number of cheeseburgers sold.
h+c=580
c=3h
4h=580

one solution to a quadratic function is -4+7i, what is the other solution?
Answer:
-4 - 7i
Step-by-step explanation:
If a quadratic equation with real coefficients has a complex number as a solution, then the complex conjugate of that number is also a solution.
Assuming the coefficients of the quadratic function are real, then the other solution is
-4 - 7i

I know the answer but can not create it on here sorry....Brighton Company launched a new gaming console. They sold 200 consoles prior to the launch.
The number of consoles sold each day after the launch is shown by the graph below.
Answer: in the domain of this situation, there is no asymptote.
Step-by-step explanation:
Asymptote would be on the left where x is negative but this function only shows all positive values of X
The value of k is -0.25. The graph shows that the actual number of consoles sold is slightly higher than the predicted number of consoles sold.
The graph shows that the number of consoles sold each day after the launch of the Brighton Company gaming console follows an exponential decay pattern. This means that the number of consoles sold each day is decreasing at a rate that is proportional to the number of consoles that have already been sold.
The equation that can be used to model this exponential decay pattern is:
N = A * [tex]e^{-kt[/tex]
where:
N is the number of consoles sold on day t
A is the initial number of consoles sold (200 consoles)
k is a constant that determines the rate of decay
e is the base of the natural logarithm
We can use the data from the graph to estimate the value of k. The first day after the launch, 180 consoles were sold. This means that on day 1, N = 180. The initial number of consoles sold, A, is known to be 200 consoles. Therefore, we can write the following equation:
180 = 200 * [tex]e^{-kt[/tex]
Solving for k, we get:
k = -ln(1.8) / 1
≈ -0.25
The value of k is approximately -0.25. This means that the number of consoles sold each day is decreasing at a rate of 25%.
We can use the equation to predict the number of consoles sold on future days. For example, on day 2, we would predict that 150 consoles would be sold. On day 3, we would predict that 120 consoles would be sold.
The graph shows that the actual number of consoles sold is slightly higher than the predicted number of consoles sold. This is because the exponential decay pattern is not perfect. There are other factors that can affect the number of consoles sold, such as the availability of the console and the price of the console.

Camden drove 320 miles in 8 hours. If he continued at the same rate, how far would he travel in 7 hours?
Answer:
280 miles
Step-by-step explanation:
We want to determine what speed Camden is going first so we can find the distance. To do so, you can divide the total miles (320) by the number of hours (8) to find he is driving 40 miles per hour. Then, you can take that and multiple it by the number of hours he will drive (7) to get 280 miles. I hope this helps! :)
