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

I have $225.00 in my account. I can spend al but 20% of that on some new equipment. What is the most that I can afford to spend

Setler79 [48]

You can "spend all but 20%" so that means you can spend up to 80% of your money (since 20%+80% = 100%). Apply 80% to the value 225

80% of 225 = (80/100)*225 = 0.80*225 = 180

The most you can afford to spend is $180

What is the range of the function f(x)= square root of x-8+6

Shtirlitz [24]

Answer:

The range of the given function is [6, + ∞)

Step-by-step explanation:

It is assumed the function is:

$f(x)=\sqrt{x-8} +6$

We know the square root is non-negative, so:

x - 8 ≥ 0 therefore the function gets values

f(x) ≥ 0 + 6
f(x) ≥ 6

We can show this as:

f(x) ∈ [6, + ∞)

What is the slope of the line that passes through the points (6, 4) and (3, 8)?

baherus [9]

Slope: (y2-y1)/(x2-x1)
(8-4)/(3-6) = 4/-3
The slope is -4/3
