Answer:
y-1=-3/4(x+8)
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept,
y-y1=m(x-x1)
y-1=-3/4(x-(-8))
y-1=-3/4(x+8)
Answer:
<u>36.87</u>
Step-by-step explanation:
We can use SOH CAH TOA (sine, cosine, and tangent) to solve this problem.
SOH- means Opposite over Hypotenuse
CAH- means Adjacent over Hypotenuse
TOA- mean Opposite over Adjacent
U can use either one of these to solve this problem, I will be using sine SOH (sine).
sine C = 3/5
sine ^-1 3 divided by 5 =36.8698
So, angle C = 36.8698 and rounded to the nearest hundred is <u>36.87</u>
Answer:
Step-by-step explanation:
We are given:
And we want to solve this via completing the square.
First, we will subtract 3 from both sides. This yields:
Next, we will factor out the leading coefficient from the left.
In this case, the leading coefficient is simply 1 so we can leave it as is.
Next, we want to add a constant that is half of the b coefficient squared.
In this case, b = -5.
Half of that is -5/2.
Squaring yields 25/4.
So, we will add 25/4 to both sides. Since our leading coefficient is 1, we don't need to multiply by anything when we add it on the right. Hence:
The left side constitutes a perfect square trinomial as shown:
Factor and subtract:
Taking the square root of both sides gives:
Hence:
Approximate:
Answer: 641
I believe this is correct, but I did it fast so unsure.. hope this helps :)
