Answer:

6. -16

7. x = -7

Step-by-step explanation:

-3×(7+(-3)²)÷3

= -3×(7+9)÷3

= -3×16÷3

= -3 × (16/3)

= -16

9 × x = -63

=> 9x = -63

=> x = -63/9

=> x = -7

Answer:

Step-by-step explanation:

6. Use PEMDAS

-3 x (7 + (-3)*2) / 3

-3 x (7 + 9) / 3

-3 x 16 / 3

-48 / 3

-16

7. 9 (x) = -63

X = - 63 /9

X = -7

A triangle has sides measuring 7 centimeters and 13 centimeters that form an angle measuring 44°. Which of these is CLOSEST to t

Oliga [24]

Answer:

9.3 centimeters

Step-by-step explanation:

If the length of the third side of the triangle is c, then according to the Law of Cosines, c2 = 72 + 132 – 2(7)(13)(cos 44°). The value of c2 can be simplified to approximately 49 + 169 – 130.9198, or 87.0802, using a calculator. By taking the square root of 87.0802, the length of the third side of the triangle comes out to be approximately 9.3 centimeters.

Is it possible that the image of a point after a reflection could be the same point as the preimage?

Vera_Pavlovna [14]

Yes, it is possible. For example, let's say that point A is (0,4) and there's a reflection over the y-axis, then point A would still be (0,4).

A ball is thrown upward with an initial velocity of 96 ft/sec from a height 640 ft. Its height h, in feet, after t seconds is

olchik [2.2K]

Check the picture below.

thus is at 0 = -16t² + 96t +640,

$\bf 0=-16t^2+96t+640\implies 0=-16(t^2-6t-40)
\\\\\\
0=t^2-6t-40\implies 0=(t-10)(t+4)\implies t=
\begin{cases}
\boxed{10}\\
-4
\end{cases}$

well, clearly it can't be a negative value for the elapsed seconds, so it can't be -4.
