1st 2nd 4th ones are correct
Answer:
The height of the flagpole is
Step-by-step explanation:
we know that
If two figures are similar, the the ratio of its corresponding sides is proportional
Remember that
Convert the measures in inches
Convert inches into (feet + inches)
1)
f(x) = x² + 9 g(x) = 24 + 4x
f(4) = (4)² + 9 g(-1) = 24 + 4(-1)
= 16 + 9 = 24 - 4
= 25 = 20
****************************************************************
g(x) = 2ˣ - 4 f(x) = 4x² - 5x - 5
g(6) = 2⁶ - 4 f(-5) = 4(-5)² - 5(-5) - 5
= 64 - 4 = 100 + 25 - 5
= 60 = 120
***************************************************************
f(x) = (3x + 7)²
f(1) = (3(1) + 7)²
= (3 + 7)²
= (10)²
= 100
****************************************************************
3xy + 2x² - y³ ; when x = 6 and y = -2
3(6)(-2) + 2(6)² - (-2)³
-36 + 72 - (-8)
36 + 8
44
If you reflect over the y-axis, then all you need to do is change the sign on the x coordinate.
so
A' = (2,5)
B' = (3,6)
Arc length = c* r where c = angle in radians and r = radius
= 0.25 * 4
= 1 inch
