The graph of the function P(x) = −0.74^2 + 22x + 75 is shown. The function models the profits, P, in thousands of dollars for a

Juliette [100K]

Answer: 5.6 ≤ x ≤ 24.13.

Step-by-step explanation:

Given, The graph of the function $P(x) = -0.74^2 + 22x + 75$ . The function models the profits, P, in thousands of dollars for a tech company to manufacture a calculator, where x is the number of calculators produced, in thousands.

In graph , On axis → number of calculators produced

On y-axis → profit made in thousands of dollars.

From the graph, the curve goes for y > 175 from x = 5.6 to x= 24.13 ( approx)

So, the reasonable constraints for the model 5.6 ≤ x ≤ 24.13.

So, If the company wants to keep its profits at or above $175,000, reasonable constraints for the model 5.6 ≤ x ≤ 24.13.

Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartF

Firdavs [7]

The length 2.3 and 7.8 units

We have given that ΔABC, c = 5. 4, a = 3. 3, and measure of angle A = 20 degrees.

<h3>What is the formula for low of cosine?</h3>

The Law of Cosines, which tells us

$a^{2}=b^{2} +c^{2} -2bccosA$

giving us a quadratic equation for b we can solve. But let's do it with the Law of Sines as asked.

$\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}$

We have c,a,A so the Law of Sines gives us sin C

$sinC=\frac{csina}{a} =\frac{5.4sin20}{3.3} =0.5597$

There are two possible triangle angles with this sine, supplementary angles, one acute, one obtuse

$C_{a}=arcsin(0.5597)=34.033^{0}$

$C_{0}=180-C_{a} =145.96^0$

Both of these make a valid triangle with A=20°. They give respective B's:

$B_{a}=180-A-C_{a} =125.96^0$

$B_{0}=180-C_{0} =14.033^0$

So we get two possibilities for b:

$b=\frac{asinB}{sinA} \\\\b_{a} =\frac{3.3sin125.96}{sin 20} \\\\b_{a}=7.8\\\\ b_0=2.3$

2.3 units and 7.8 units

Therefore we get the length 2.3 and 7.8 units

Answer: 2.3 units and 7.8 units

Let's check it with the Law of Cosines:

There's a shortcut for the quadratic formula when the middle term is 'even.'

Looks good.
