Answer:
Im not sure exactly what you want the function to be. Because it can be any number. only the signs would change it
Step-by-step explanation:
okay so lets try this then..
if f(x) is an even number...let say 2
then f(-2)= 2x²+x+6
then it would be 2(-2²)+(-2)+6......-4

Answer:
Step-by-step explanation:
Use Pythagorean theorem.
Hypotenuse² = base² + altitude²
5) x² = 12² + 6²
= 144 + 36
x² = 180
x = √180
x = 13.42 ft
6) 25² = x² + 19²
625 = x² + 361
625 - 361 = x²
x² = 264
x = √264
x = 16.25 m
7) x² = 7² + 576
= 49 + 576
= 625
x = √625
x = 25 in
8) 2.5² = 2²+ x²
6.25 = 4 + x²
6.25 - 4 = x²
x² = 2.25
x = √2.25
x = 1.5 yd

Answer:
41
Step-by-step explanation:
Given
(7 + 2
)(7 - 2 ) ← expand factors using FOIL
= 7² - 2 + 2 - (2 )² ← collect like terms
= 49 - 8
= 41
Answer:
Option C
Step-by-step explanation:
We will analyze the figure and note down the properties given in the figure,
1). LK is a diameter so this line (chord) divides the circle into two arcs measuring 180°.
m(arc LJK) = m(arc LK) = 180°
2). m(∠JKL) = 28°
Therefore, by the property inscribed angle and intercepted arcs,
Intercepted arc (JL) = 2 × (Inscribed angle JKL)
m(arc JL) = 2(26°)
= 52°
Now we will use these two points to get the measure of arc JK.
m(arc JK) + m(arc LK) + m(arc JL) = 360°
m(arc JK) + 180° + 52° = 360°
m(arc JK) = 360° - 232°
= 128°
Option C will be the correct option.
