From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°
Answer:
The range of the function is represented by ![Ran\{f(x)\} = (-15, 12]](https://tex.z-dn.net/?f=Ran%5C%7Bf%28x%29%5C%7D%20%3D%20%28-15%2C%2012%5D)
.
Step-by-step explanation:
Let be 
, for 
. As we notice that 
is an inyective function, that is, the inexistence of two or more domain element with the same image, with a monotone behavior, we can obtain the bounds of the range of the function by evaluating the expression:
Lower bound (
)
Upper bound (
)
The range of the function is represented by
Answer it is 456y5445t6y5432
Step-by-step explanation:
ww
<span>7r²+9=1
</span><span>the equation is contradictory, just to prove
7r</span>² + 9 = 1
7r² + 9 -1 = 0
7r² + 8 = 0
<span>We write the equation in the form of products of
</span>
7 * (r² + 8/7) = 0
<span>the product is equal to 0 when one of the factors is zero
</span>
7≠0 ∨ (r² + 8/7) = 0
r² ≠ - 8/7
<span>any number squared is not negative.
</span><span>We proved that none of the factors is not equal to zero , so the right side of the equation is not equal to the left . The equation is contradictory</span>
