In a right triangle, what is the 3rd angle measure if an angle is 25
melomori [17]

Answer:

65

Step-by-step explanation:

The sum of the angles in a triangle is 180. In a right triangle, there is one 90 degree angle. If the second angle is 25, and 90+25+the last angle must add up to 180, simple math can find the value of the last angle.

180-90-25=65

Which function represents a reflection of f(x) =
liubo4ka [24]

If your original equation was f(x) = 3(2)^x, then a reflection over the x-axis means you need all the y-values to switch sign.  This means you need to multiply that function by -1.

    g(x) = -1\cdot 3(2)^x or  g(x) = -3(2)^x

What is the range of the following function: f(x)=-x^2+x^-1 if the domain is {-2, -1, 1}
postnew [5]

f(x)= -x^2 + x^-1

f(-2)= - (-2)^2 + (-2)^-1 = -4 - 1/2 = -9/2

f(-1)= - (-1)^2 + (-1)^-1 = -1 -1    =   -2

f(1) = - (1)^2 + (1)^-1 = -1 +1 = 0

The range is { -9/2, -2, 0}
