Rewrite f(x) = -(x + 3)2 - 1 from vertex form to standard form. (2 points)
Mandarinka [93]

Answer:

f(x) = -x^2 - 6x - 10

Step-by-step explanation:

Please write the original equation as  f(x) = -(x + 3)2 - 1, as "(x + 3)2 is meaningless.  We want:

f(x) = -(x + 3)^2 - 1, where " ^ " denotes exponentiation.

Expanding this, we get:

f(x) = -(x^2 + 6x + 9) - 1, or

f(x) = -x^2 - 6x - 9 - 1, or:

f(x) = -x^2 - 6x - 10          This matches the first answer choice.

Given 1+cosx\sinx+sinx\1+cosx=4, find a numerical value of one trigonometric function of x.
Len [333]

Answer:

Option d. sin(x)=\frac{1}{2}

Step-by-step explanation:

<u><em>The complete question is</em></u>

Given (1+cosx)/(sinx) + (sinx)/(1+cosx) =4, find a numerical value of one trigonometric function of x.

a. tanx=2

b. sinx=2

c. tanx=1/2

d. sinx=1/2

we have

\frac{1+cos(x)}{sin(x)}+\frac{sin(x)}{1+cos(x)}=4

Find the common denominator and adds the fractions

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

Expanded the numerator

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

Remember that

sin^2(x)+cos^2(x)=1 ----> trigonometric identity

substitute

\frac{1+2cos(x)+1}{(1+cos(x))sin(x)}=4

\frac{2+2cos(x)}{(1+cos(x))sin(x)}=4

Factor 2 in the numerator

\frac{2(1+cos(x))}{(1+cos(x))sin(x)}=4

Simplify

\frac{2}{sin(x)}=4

sin(x)=\frac{1}{2}

There is a Chick-fil-a exactly 6 miles due east of Berkmar Middle School. There is also a Wal-Mart 6 miles due north of Berkmar
Vedmedyk [2.9K]

Answer:

6√2 miles

Step-by-step explanation:

Using the solution diagram drawn :

We have a right angled triangle, the distance between Walmart mad chick-FIL is a measure of the hypotenus of the right angled triangle ;

The hypotenus, = √(opposite² + adjacent²)

Hypotenus = √6² + 6²

Hypotenus = √(36 + 36)

Hypotenus = √72

Hypotenus = √36 * 2 = √36 * √2 = 6√2 miles
