Answer:
the k value is 6
Step-by-step explanation:
The form of a qruadratic equation is f(x)=a(x-h)^2 + k, so by comparing this to the function f(x)=-18(x-2)^2 + 6 we can see that K = 6, a = -18,and h = 2.
Answer:
f(-3) = 44
Step-by-step explanation:
f(x) = 2x² - 5x + 11
Substitute the value.
f(-3) = 2(-3)² - 5(-3) + 11
Raise -3 to the power of 2.
f(-3) = 2(9) - 5(-3) + 11
Multiply 2 and 9.
f(-3) = 18 - 5(-3) + 11
Multiply -5 and -3.
f(-3) = 18 + 15 + 11
Add 18 and 15.
f(-3) = 33 + 11
Add 33 and 11.
f(-3) = 44
Answer:
38 = D
Step-by-step explanation:
The 3 angles of a triangle equal 180 degrees
<B + <C + <D = 360
7x+ 12 + 2x+13 + 2x+ 12 =180
Combine terms
11x+37 = 180
Subtract 37 from each side
11x+37-37 = 180-37
11x =143
Divide by 11
11x/11 = 143/11
x =13
We want to find angle D
2x+12 = D
2(13) + 12 = D
26+12 = D
38 = D
Answer:
A.) <em>m ∠ ABD = m ∠ CBD</em>
Step-by-step explanation:
The line segment BD was constructed as an angle bisector, which means that ∠ ABC was split directly in half. This means that the two resulting angles are congruent.
