The constant is 140. It represents the revenue generated with no increase in price; that is, x = 0. By selling 70 hot dogs at $2 each, the volunteers earn 70 • $2 = $140.

In APQR, P = 83°, p = 285 m, r = 216 m.<br>Calculate R.

vladimir1956 [14]

Answer:

48.8°

Step-by-step explanation:

We solve using sine rule

The formula is given as

p/sin P = r/sin R

In APQR, P = 83°, p = 285 m, r = 216 m.

Calculate R.

Hence, solving for R

285/sin 83 = 216/sin R

Cross Multiply

285 × sin R = sin 83 × 216

sin R = sin 83 × 216/285

R = arc sin (sin 83 × 216/285)

R = 48.78527°

Approximately = 48.8°

Therefore, R = 48.8°

The product of some negative number and 4 less than twice that number is 286 find the number

Naya [18.7K]

Let's say that number is hmmm "a"

now.. twice "a" is 2*a or 2a
4 less than that is " 2a - 4"

now, the product of those two fellows is 286, well ok

a( 2a - 4) = 286

thus

$\bf a(2a-4)=286\implies 2a^2-4a^2=286\implies a^2-2a^2=143
\\\\\\
a^2-2a^2-143=0\implies (a-13)(a+11)=0
\\\\\\
\begin{cases}
a-13=0\implies &a=13\\
a+11=0\implies &\boxed{a=-11}
\end{cases}$
