3rd quadrant. Below is a picture that explains what is positive and in what quadrant. I use the term All students take calculus. If you start in the 1st and go through 2nd, 3rd and forth:

A in all stands for All positive
S in students stands for sin and its inverse (csc) is positive.
T in take stands for tan and its inverse (cot) is positive.
C in calculus stands for cos and its inverse (sec) is positive.

you have nine coins: a collection of pennies, nickels, dimes, and quarters having a total value of $1.02, with at least one coin

raketka [301]

1 dime is required to make $1.02 cents using 9 coins collections

<h3>How to solve</h3>

Given data

9 coins

a collection of pennies, nickels, dimes, and quarters

total of $1.02 with at least one coin of each type

solution

$1.02 = 102cents

1 penny = 1 cent

1 nickel = 5 cents

1 dime = 10 cents

1 quarter = 25 cents

having one coin of each means 4 coins which is equal to:

1 + 5 + 10 + 25 = 41 cents (fulfilling the first condition remaining 5 coins)

102 - 41 = 61

balancing the remaining coins to make up 61, we first get a penny to reduce the amount 60 cents ( 4 coins remaining )

hence we have

2*25 +2*5 = 60 cents ( 2quarters 2 nickel)

in total we have

2 pennies + 3 nickels + 1 dime + 3 quarters = 9 coins

2 * 1 + 3 * 5 + 1 * 10 + 3 * 25 = 102 cents

Therefore 1 dime is required to make $1.02 cents using 9 coins collections

Find an equation for the line below.

Nuetrik [128]

Answer:

f(x) = -5/3x + 5/3

Step-by-step explanation:

if x = 4 ; f(x) = -5

if x = -2 ; f(x) = 5

f(x) = ax + b

-5 = 4a + b (1) 

and

5 = -2a + b (2)

(1) + (2) 

2a + 2b = 0

a = -b

(1) -5 = 4a - a

-5 = 3a

a = -5/3

Answer :

f(x) = -5/3x + 5/3

Find the value of x by using law of sines.

Pavel [41]

Answer:

x = 7.7

Option B

Step-by-step explanation:

$\frac{a}{Sin~A} &=& \frac{b}{Sin~b} \\ \frac{8}{Sin~73^\circ} &=& \frac{x}{Sin~67^\circ} \\ \frac{8}{0.96} &=& \frac{x}{0.92} \\ 0.96x &=& 8 \times 0.92 \\ 96x &=& 8 \times 92 \\ 96x &=& 736 \\ x &=& \frac{736}{96} \\ x&=& \frac{23}{3} \\ &\boxed{x=7.7}&$

∴ value of x is 7.7

The graphs below have the same shape. The equation of the blue graph is f(x) = 2x. Which of these is the equation of the red gra

Allisa [31]

The main thing you want to ask yourself is "What is the difference between the two graphs?"

As we can see, the graphs look identical in every way except that g(x) is lower than f(x).

This means that the graph is shifted down a certain amount.

If we look at the y-intercepts of the two functions, we see that f(x) has a y-intercept of 1, and g(x) has a y-intercept of -1.

This means that f(x) is two units lower than g(x).

The y-intercept of a function can be changed by adding or subtracting a number to the original function (in this case 2^{x}).

Because the graph f(x) is 2 lower than the graph of g(x), we can find g(x) by subtracting 2 from f(x).

Therefore, g(x) = 2^{x} - 2.
