The function y = –5(x – 4)2 + 10 shows the daily profit (in hundreds of dollars) of a taco food truck, where x is the price of a

aliya0001 [1]

We have the following function:
y = -5 (x - 4) ^ 2 + 10
Rewriting we have:
y = -5 (x ^ 2 - 8x + 16) + 10
y = -5x ^ 2 + 40x - 80 + 10
y = -5x ^ 2 + 40x - 70
Which roots are:
x1 = 4-root (2)
x2 = 4 + root (2)
Interpretation for one of the roots:
x2 = 4 + root (2):
By increasing the price of the product, the demand for it decreases.

Answer:
the zeros of this function are:
x1 = 4-root (2)
x2 = 4 + root (2)
one for the interpretation:
x2 = 4 + root (2):
By increasing the price of the product, the demand for it decreases.

Pls help me solve the problem

Answer:

The 54th term is -855

Step-by-step explanation:

Since the sequence is arithmetic, then we have to use the rule of the nth term

$a_{n}=a+(n-1)d$

a is the first term

d is the common difference

n is the position

The given sequence is -7, -23, -39

a=-7

d=-23-(-7)=-23+6=-16

We need to find the 54th term

n=54

Substitute them in the rule

$a_{54}=-7+(54-10)(-16)$

Solve it:

$a_{54}=-7+(53)(-16)\\
 a_{54}=-7-848\\
 a_{54}=-855$

The 54th term is -855

Find the value of csc 0, if cos 0= - 2/3 ; 180 < 0< 270

Amiraneli [1.4K]

Answer:

D

Step-by-step explanation:

apply pythagorean theorem to find sin of theta.

$\cos( \frac{2}{3} ) {}^{2} + \sin(x) {}^{2} = 1$

$(\frac{4}{9}) {}^{2} + \sin(x) {}^{2} = 1$

$\sin(x) {}^{2} = \frac{5}{9}$

$\sin(x) = \frac{ \sqrt{5} }{3}$

Find the reciprocal to find find csc.

$\frac{3}{ \sqrt{5} }$

rationalize the denominator.

$\frac{3}{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{3 \sqrt{5} }{5}$

Csc is negative in the 3rd quadrant.

so the answer is

$- \frac{3 \sqrt{5} }{5}$

D is the answer.
