Answer:
-2.44
Step-by-step explanation:
Is a right angle triangle
We apply SOHCAHTOA
SOH is sin=Opposite divided by Hypotenuse
CAH is cos=Adjacent divided by Hypotenuse
TOA is tan=Opposite divided by Adjacent
so in this case,cos is the right thing to use
Therefore,x=adjacent
15=Hypotenuse
angle=52°
Cos(52)=x÷15
making x the subject,
x=15cos(52)
x= -2.44
Answer:
Step-by-step explanation:
1) Remove parentheses.
2) Regroup terms.
Answer:
132.25 feet
Step-by-step explanation:
Since the function is a quadratic representing height, and the coefficient of the t² is negative, the vertex of the parabola will be the maximum height achieved by the ball.
The general form for a quadratic equation is ax² + bx + c,
here a is -16, and b is 92
To find the x coordinate of the vertex, use x = -b/(2a)
We have x = -92/[2(-16)]
x = -92/-32
x= 23/8
Now plug that into the equation to find the y value, which will be the height...
y = 92(23/8) - 16(23/8)²
y = 2116/8 - 16(529/64)
y = 1058/4 - 529/4
y = 529/4
y = 132.25
The question is not attach!
Well i think you have to draw a picture .so Let x be the vertical distance of the ladder from the top of the wall to the ground. Start with a 65degrees angle. sin65degrees = x/11,x = 9.969.If the angle is less than 65degrees, then x will be less than 9.969. The answer is it is not possible
