Answer:

The product is $x^3+5x^2$

Step-by-step explanation:

This is because we apply the distributive property of multiplication.

Thus from $x(5x+x^2)$

we get this:

$x*5x+x*x^2$

$x*5x$ is $5x^2$ and $x*x^2$ is $x^3$

Which expression is equal to sec x° multiplied by cot x°?

Over [174]

Sec x is equal to 1/cosx, cot x is equal to cosx/sinx. cos x cancels, and you are left with 1/sinx. this is equal to cscx. Cosecant is : hypotenuse / opposite, so the answer is **D**

1. Find the value of

spin [16.1K]

9514 1404 393

Answer:

-√5
3/5
-4/5

Step-by-step explanation:

The relevant relations are ...

sec = ±√(tan² +1)

cos = 1/sec

csc = 1/sin = ±1/√(1 -cos²)

Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.

1. sec(θ) = -√((-2)² +1) = -√5

2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5

3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5
