Please help. I need help with # 36. Thanks

Xelga [282]

I would say that the answer is B. First because the line AB is descending from left to right which shows that it is negative. Secondly, the gradient 3 would be steep and the gradient 1/3 would not be as steep which is why iI would say it is 1/3. Overall, the answer would be negative and 1/3 which would be B.

PLEASE SOMEONE HELP ME ANSWER THIS !!!!

Mumz [18]

Step-by-step explanation:

Part A: Linear Equation.

One of the points is (0,15). This means 0,15 is the y intercept so b=15.

We can find the slope

$\frac{5 - 15}{1 - 0 } = \frac{ - 10}{1} = - 10$

So our equation is

$y = - 10x + 15$

Part B: Exponential Equation

We know that

$15 = a \times b {}^{0}$

B to the zero power is 1 so

$15 = a$

This means a =15. Now let find b.

$5 = 15 \times b {}^{1}$

$\frac{1}{3} = b$

So the equation is

$y = 15( \frac{1}{3} ) {}^{x}$

A triangle is cut from a<br> rectangle. Find the area<br> of the shaded region.

KATRIN_1 [288]

The area of rectangle:

11 ft · 6 ft = 66 ft²

The area of triangle:

6 ft · 4 ft/2 = 6 ft · 2 ft = 12 ft²

The area of the shaded region:

66 ft² - 12 ft² = 54 ft²

4 sin ^ 2 x- 4 sin x + 1 = 0

m_a_m_a [10]

$4\sin^2x-4\sin x+1=(2\sin x-1)^2=0\implies \sin x=\dfrac12$

This happens for $x=\dfrac\pi6+2n\pi$ and $x=\dfrac{5\pi}6+2n\pi$ where $n$ is any integer.
