Answer:

QII

Step-by-step explanation:

We can use the acronym: ASTC or All Students Take Calculus.

The first letter of each word tells us details within a certain quadrant.

All trig functions in QI will be positive.

Only sine (and cosecant) will be positive in QII.

Only tangent (and cotangent) will be positive in QIII.

And only cosine (or secant) will be positive in QIV.

We know that tan(θ)<0. In other words, it's negative.

So, it our angle θ cannot be in QI or QIII.

We also know that cos(θ)<0.

So, this removes QIV, since in QIV, cosine is positive.

Therefore, the only choices that remains is QII.

In QII, sine is positive, tangent is negative, and cosine is negative.

This fits all our conditions, so θ is in QII.

And we're done!

1. 10(.15)=1.5

Fed [463]

Answer:

6.14125(0.15) = 0.9211875 (below 1)

6.14125 - 0.92118 = 5.22007

Step-by-step explanation:

Given data

1. 10(.15)=1.5

2. 10-1.5=8.5

3. 8.5 (.15)=1.275

4. 8.5-1.275=7.225

continuation the sequence

5) 7.225 (0.15) = 1.08375

6) 7.225 - 1.08375 = 6.14125

7) 6.14125(0.15) = 0.9211875 (below -one)

8 ) 6.14125 - 0.9211875 = 5.2200625 (get number 5)

9) 5.2200625(0.15) = 0.783009

10) 5.2200625 - 0.783009 = 4.4370532

Someone help me with these two. I'll give you brainliest and 25 points!! MATHEMATICIANS OUT THERE HELP

Hello LovingAngel!

To find the slope, you can use the formulas $\frac{rise}{run}$ as well as $\frac{y^2-y^1}{x^2 - x^1}$ . I am using the latter to calculate and ensuring my answer with the former.

[Note: (x,y) is the format for ordered pairs]

First pair: value 1:(1,5) and value 2:(2,8)
$\frac{y^2-y^1}{x^2 - x^1}$ -> $\frac{8 - 5}{2 - 1}$ -> $\frac{3}{1}$ or 3.

The slope for (1,5) and (2,8) is 3(/1).

Second pair: value 1: (3,1) value 2 (3,-1)

$\frac{y^2-y^1}{x^2 - x^1}$ -> $\frac{-1 - 1}{3 - 3}$ -> $\frac{-2}{0}$
Slope for the second pair is -2/0

Checking work with $\frac{rise}{run}$
1. Slope: 3/1, meaning rise (y) +3 and run (x) +1. (1,5) -> (1+1,5 + 3) -> (2,8) ✔
2. Slope: -2/0, meaning rise (y) -2/drop (y) 2 and run 0. (3,1) -> (3 + 0, 1 + -2) -> (3,-1) ✔

John and Beth plan to visit a bookstore. Based on their previous visits to this bookstore, the probability distributions for the

lora16 [44]

Answer:

D) 0.1250

Step-by-step explanation:

Let P(J) = Probability of John to purchase 0 books

Let P(B) = Probability of Beth to purchase 0 books

P(J∩B) = Probability that both john and Beth will purchase 0 books .ie. a total of 0 books is purchased.

Since the decisions to purchase books are two independents events,

P(J∩B) = P(J) * P(B)

P(J) = 0.5

P(B) = 0.25

P(J∩B) = 0.5 * 0.25

P(J∩B) = 0.125
