$\\ \sf\longmapsto cos31=\dfrac{12}{x}$

$\\ \sf\longmapsto 0.85=\dfrac{12}{x}$

$\\ \sf\longmapsto x=\dfrac{12}{0.85}$

$\\ \sf\longmapsto x=14.11$

Answer:

y = 6x - 9

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (4, 15)

Point (-1, -15)

Step 2: Find slope m

Substitute: $m=\frac{-15-15}{-1-4}$
Subtract: $m=\frac{-30}{-5}$
Divide: $m=6$

Step 3: Find y-intercept b

Define: y = 6x + b
Substitute: -15 = 6(-1) + b
Multiply: -15 = -6 + b
Isolate b: -9 = b
Rewrite: b = -9

Step 4: Write linear equation

Substitute in all variables.

y = 6x - 9

What will go Inside the boxes?

e-lub [12.9K]

Answer:

18500 is the initial value

Every year they increase by a factor of 1.03

Step-by-step explanation:

This is written in the form

y = ab^x where a is the initial value and b is the growth rate/decrease

y = (18500) (1.03)^t

The initial value is 18500

The students will increase by 1.03 - 1 = .03

The factor of increase is what they multiply by which is 1.03

HELP! 15 POINTS!

Brut [27]

It's pretty easy to go through the choices and none has a[2]=-36 and a[5]=2304. Something's probably wrong with the way the question is typed, but I will answer what's written.

$a_n = a + (n-1) d$

$a_2 = -36 = a + d$

$a_5 = 2304 = a + 4d$

Subtracting,

$2340 = 3d$

$d = 2340/3 = 780$

$a = -36 - d = -36 - 780 = -816$

Answer: a[n] = -816 + 780(n-1) which is none of the above

Check:

$a_2 = -816 + 780= -36 \quad\checkmark$

$a_5 = -816 + 780(4) = 2304 \quad\checkmark$
