Answer:
x ≈ 36.2
Step-by-step explanation:
Since the legs are congruent then the triangle is isosceles.
The altitude bisects the base and divides the triangle into 2 right triangles.
Using the right triangle on the right with legs 33 and 15
Apply Pythagoras' identity to the right triangle, that is
x² = 33² + 15² = 1089 + 225 = 1314 ( take the square root of both sides )
x = ≈ 36.2 ( to 1 dec. place )
They want you to find the composite function and they evaluate it at a give value for x...first the composite function...
f(g(x))=(x-1.5)^2+3(x-1.5)+6
f(g(x))=x^2-3x+2.25+3x-4.5+6
f(g(x))=x^2+3.75, this is the completed composition function...now:
f(g(1)=1+3.75=4.75
Answer:
6 (2 x - 3)
or a simplefied version:
12x - 18
Step-by-step explanation:
Answer:
Step-by-step explanation:
The answer is 7, Because if AC is 12 the radius would be half of that and you would get 7.
Hope I helped.
Answer:
angle edf is 70
Step-by-step explanation:
triangle angles always add up to 180. So if you have 40 degrees at angle e already, 180-40 = 140
since side DE and side EF are congruent, that means its an isosceles triangle. One rule for that type a triangle is that the two base angles are equal. So you can just do 140/2 = 70
hope that helps!
