The answer to your question is below

Step-by-step explanation:

(2x⁴ + 7x³ - 3x + 9) - (6x⁴ - 3x³ - 6x² - 17)

Step 1. take out the parenthesis, in the second term, change the signs

2x⁴ + 7x³ - 3x + 9 - 6x⁴ + 3x³ + 6x² + 17

Step 2. Group like terms

(2x⁴ - 6x⁴) + (7x³ + 3x³) + (6x²) + (-3x) + (9 + 17)

Step 3. Simplify like terms

-2x⁴ + 10x³ + 6x² - 3x + 26

zhuklara [117]

Answer:

resistance: (2r +5)
current: (3i +4)

Step-by-step explanation:

The factors of the given expression are ...

6ir +15i +8r +20 = (3i +4)(2r +5)

Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...

resistance: (2r +5)

current: (3i +4)

Find cscθ.<br><br>pls answer

ExtremeBDS [4]

Answer:

The answer to your question is csc Ф = $\frac{-5}{4}$

Step-by-step explanation:

Process

1.- Determine the sign

We must determine csc Ф in the forth quadrangle, here csc is negative.

2.- Determine the hypotenuse

c² = a² + b²

c² = 3² + (-4)²

c² = 9 + 16

c² = 25

c = 5

3.- Determine csc Ф

csc Ф = $\frac{hypotenuse}{opposite side}$

csc Ф = $\frac{5}{-4}$ = $\frac{-5}{4}$
