Answer:

A = $16\pi$ $cm^{2}$

Step-by-step explanation:

∵ The diameter of the mug is 8 cm and using to cut out circular cookies

∴ The diameter of each circular cookie is 8 cm

∴ Its radius = 8 ÷ 2 = 4

∵ Area of the circle = $\pi r^{2}$

∴ Area = $\pi 4^{2}=16\pi cm^{2}$

For the functions f(x)=−7x^2−x and g(x)=9x^2−4x, find (f−g)(x) and (f−g)(1)

musickatia [10]

Answer:

See below.

Step-by-step explanation:

$f(x)=-7x^2-x\\g(x)=9x^2-4x\\(f-g)(x)=f(x)-g(x)\\(f-g)(x)=(-7x^2-x)-(9x^2-4x)\\(f-g)(x)=-7x^2-x-9x^2+4x\\(f-g)(x)=-16x^2+3x\\\\(f-g)(1)=-16(1)^2+3(1)\\(f-g)(1)=-16+3=-13$

If two congruent angles form supplementary, they are acute angles true or false

juin [17]

Answer:

false

Step-by-step explanation:

No, two acute angles cannot form a supplementary angle. By definition, acute angles are the angles that measure the angle greater than 0° and less than 90°. ... Example: 80° +60° = 140° which is not a supplementary angle. But, in the case, if we add more than two acute angles, we can get supplementary angles.
