Answer: a=4, b=16, c=12

Step-by-step explanation:

Use the intercept form: a(x - p)(x - q) where p & q are the intercepts.

Given: p = -3, q = -1, and y-intercept (c) = 12

a[x - (-3)][x - (-1)]

= a(x + 3)(x + 1)

= a(x² + 4x + 3)

= ax² + 4ax + 3a

y-intercept = 12

3a = 12

a = 4

Substitute a = 4

4x² + 4(4)x + 3(4)

= 4x² + 16x + 12

If θ is an angle in standard position that terminates in Quadrant IV such that cosθ = 3/5, then cosθ/2 = _____. -

Sveta_85 [38]

Answer:

$cos \frac{\theta}{2}= 0.894$ .

Step-by-step explanation:

Given:

$cos\ \theta= \frac35$

We need to find $cos \ \frac{\theta}{2}$

Solution:

$cos\ \theta= \frac35$

First we will find the value of $\theta$ .

Now taking $cos^{-1}$ on both side we get;

$\theta= cos^{-1} \ \frac{3}{5}\\\\\theta = 53.13$

Now we will find the $\frac{\theta}{2}$ .

$\frac{\theta}{2}$ = $\frac{53.13}{2} = 26.565$

Now we will find $cos \ \frac{\theta}{2}$ we get;

$cos \frac{\theta}{2}=cos\ 26.565 = 0.894$

Hence $cos \frac{\theta}{2}= 0.894$ .

There are a total of 72 students in a drama club and a yearbook club. The drama club has 12 more students than the yearbook club

svetlana [45]

VARIABLES:
[x] Yearbook Club (expression: x)
[y] Drama Club (expression: x + 12)

EQUATIONS:
#1 x + y = 72
#2 y = x + 12

Now we shall use the method of substitution to solve.

FINDING X:
#1 x + (x + 12) = 72
#2 2x + 12 = 72
#3 2x = 60
#4 x = 30

The amount of students in the yearbook club: 30
The amount of students in the drama club: 72 - 30 = 42

If you can, please give me brainliest. Thank you!
