Can someone please help me with this

Answer:

15/17

Step-by-step explanation:

the cosine is the adjacent divided by the hypotenuse. The adjacent of a is 15 and the hypotenuse is 17 so the ratio is 15/17

Hope this helps and have a good day :)

Answer: y = (1/3)*x - 7

Step-by-step explanation:

When we have a line:

y = a*x + b

A perpendicular line to this one needs to have a slope s equal to:

s = -(1/a)

Then any line written as:

y = -(1/a)*x + c

is perpendicular to the lines of the form "y = a*x + b"

Then if we have the line:

y = -3*x - 8

The family of perpendicular lines to this one is:

y = -(1/-3)*x + c

y = (1/3)*x + c

where c can be any real number.

Now we also want that this line passes through the point (9, -4)

Then we need to replace x by 9, and y by -4

-4 = (1/3)*9 + c

Now we can solve this for c.

-4 = 9/3 + c

-4 = 3 + c

-4 - 3 = c

-7 = c

Then the line that is perpendicular to the line y = -3x – 8 and that goes through (9, -4) is:

y = (1/3)*x - 7

Answer:

x = 8

Step-by-step explanation:

The perimeter (P) is calculated as

P = 2(l + b) ← l is length and b is breadth

Here l = 12 and b = x , P = 40, then

2(12 + x) = 40 ( divide both sides by 2 )

12 + x = 20 ( subtract 12 from both sides )

x = 8

Anwser:the reflection of (-6, 8) in the y axis will be (6,8)

Step-by-step explanation:

the point (-6, 8) when reflected in the y axis will have the same y coordinate but it x coordinate will be the opposite of the x coordinate of the original point, therefore the reflection of (-6, 8) in the y axis will be (6, 8) hoped that help?

Answer:

put angel sum property on it

Step-by-step explanation:

39 + 73 + x = 180

112 + x = 180

x = 180 - 112

x = 68

put degree sign over it

Answer:-0.16666666666

Step-by-step explanation:

Answer:

The rocket will take 4.5 seconds to reach its maximum height.

Step-by-step explanation:

The height of a missile t seconds after it has been fired is given by h=-4.9*t²+44.1*t

This function is a quadratic function of the form f (x) = a*x² + b*x + c. In this case a=-4.9, b=44.1 and c=0

To calculate how many seconds it will take for the rocket to reach its maximum height, I must calculate the maximum of the function. The maximum of a quadratic function is the vertex of the parabola. The x coordinate of the vertex will be simply: [tex]x=\frac{-b}{2*a}[/tex]. The y coordinate of the vertex corresponds to the function evaluated at that point.

In this case the x coordinate of the vertex corresponds to the t coordinate. In other words, by calculating the x coordinate of the vertex, you are calculating the maximum time t it will take for the rocket to reach its maximum height. So:

[tex]t=\frac{44.1}{2*(-4.9)}[/tex]

t=4.5

The rocket will take 4.5 seconds to reach its maximum height.

Answer:

arc 1 = 100 degrees

angle 2 = 50 degrees

Step-by-step explanation:

arc 1 = 2(50)   (arc = 2 x inscribed angle)

arc 1 = 100 degrees

angle 2  = 1/2 arc 1 = 50 degrees
