Answer:

x = ±½

Though P is shown in the third quadrant so probably expecting x = -½

Step-by-step explanation:

Unit circle so radius is 1

x = √(1² - (½√3)²) = √(1 - 0.75) = √0.25 = ±½

Given that f(x) = −x 4 and g(x) = −2x − 3, solve for f(g(x)) when x = 2. −14 −7 7 11

Rudiy27

F(x) = -x + 4
g(x) = -2x - 3

f(g(x)) = -(-2x - 3) + 4 = 2x + 3 + 4 = 2x + 7
f(g(2)) = 2(2) + 7 = 4 + 7 = 11

how many pounds of candy worth $12 per pound should be mixed with candy costing $19 per pound to produce a 70 pound mixture that

sweet-ann [11.9K]

Answer:

40 pounds

Step-by-step explanation:

Given: Cost of a candy $(c_1)$ = $\$ 12$ per pound

Cost of candy $(c_2) = \$ 19\ per\ pound$

Total amount of mixture of be produced = $70\ pound$

Selling price of mixture = $\$ 15 \ per\ pound$

Let´s x be the amount of $c_1$ to be mixed in the mixture.

∴ Cost of $c_1$ in the mixture = 12x

Next, Cost of $c_2$ in the mixture = $(70 - x)\times 19$

And we know the cost of final mixture = $70 \times 15 = 1050$

Now, putting all the value in the equation

⇒ $12x + 19 \times (70 - x) = 1050$

⇒ $1330 - 7x = 1050$

⇒ $-7x = -280$

∴ $x = 40\ pound$

∴ 40 pounds of candy worth $12 per pound to be mixed in the mixture.
