Answer:
option C. 
Step-by-step explanation:
we have that
The point (-5,-12) belong to the III quadrant
so
The value of the cosine is negative
Applying the Pythagoras Theorem
Find the value of the hypotenuse
The value of cosine of angle θ is the ratio between the side adjacent to angle θ and the hypotenuse
Answer:
Step-by-step explanation:
In vertex form, the equation is
y = a(x-h)^2 + k
So just read off the values!
Answer:
Cube has larger volume than cylinder.
Step-by-step explanation:
Given:
Side of a cube = 7 cm
Radius of a cylinder (r) = 5 cm
Height of a (h) = 4 cm
Find:
Larger volume = ?
Computation:
Volume of cube = Side³
Volume of cube = 7³
Volume of cube = 343 cm³
Cube has larger volume than cylinder.
X (a + 2) = 7
First let's multiply out the brackets on the left side of the equation.
x (a + 2) --> Multiply everything inside the brackets by x.
xa + 2x = 7
Now, both elements of the left-hand side of the equation contain x, so we can divide both sides of the equation by x.
xa + 2x = 7
a + 2 = 7/x
To find a now, just subtract 2 from both sides.
a = 7/x - 2
