Answer:
I think maybe the first one??
Step-by-step explanation:
Answer: The correct option is 350.62 feets.
Step-by-step explanation:
Let the triangle Δ ABC
the length of wire = AC
Height of the pole = AB
Length between the point of attachment of wire from base of the pole = BC = 137 feets
Angle of elevation to the pole = θ = 67 °
According to trigonometry :
cosθ = ![\frac{base}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bbase%7D%7Bhypotenuse%7D)
cos 67 ° = ![\frac{BC}{AC}](https://tex.z-dn.net/?f=%5Cfrac%7BBC%7D%7BAC%7D)
![0.39=\frac{137}{AC}](https://tex.z-dn.net/?f=0.39%3D%5Cfrac%7B137%7D%7BAC%7D)
AC = 351.28 feets
351 feets.
From the given option the closest value to our answer is 350.62 feets.
Hence, the correct option is 350.62 feets.
Yes its correct. 7.4-.2=7.2
To answer this question, we would have to use algebra.
Let the unknown number be A.
Now, as per the question, we have the equation ->
2A - 7 > 5 + A
==> 2A - A > 5+7
==> A > 12
So, the final answer is --> A > 12
y = - 3(x + 1 )² + 2
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here vertex = (- 1, 2), hence
y = a(x + 1)² + 2
to find a substitute (1, - 10) into the equation
- 10 = 4a + 2 ⇒ 4a = - 12 ⇒ a = - 3
y = - 3(x + 1)² + 2 ← in vertex form
