Answer:

Square roots are a number multiplied by the same number.

Therefore 2 x 2 = 4

3 x 3 = 9

To simplify this fraction as a square root, they are both perfect squares so the answer would be 2/3

Simplify and write the trigonometric expression in terms of sine and cosine:

kicyunya [14]

Answer:

f(x) = + cosx or - cosx

Step-by-step explanation:

(2+tan^2x/sec^2x) -1 =(f(x))^2

=(( 1 + sec^2x)/sec^2x) -1

= 1 / sec^2x + 1 - 1

= 1 / sec^2x

= cos^2x

(f(x))^2 = cos^2x

f(x) = + cosx or - cosx

Solve this for x. I have had 3 tries and can’t get the right answer.

Tanya [424]

Let's do both. For the first one, we can add 1 to both sides using the property of equality, and get 4x < -12. Then, we divide by 4, getting us x<-3. For the second, we subtract 3 from both sides to get -2x < 4. Then, we divide by -2 on both sides, but when we divide by a negative we have to switch the sign. So, we get x > -2. Hope this helps.

graph the system of inequlities {-2x+3y>3 and 4x-3y<15. a solve each inequality for y show your work. graph each inequalit

Stels [109]

Answer:

See explanation

Step-by-step explanation:

1. Solve the system of two inequalities for y:

$\left\{\begin{array}{l}-2x+3y>3\\ \\4x-3y3+2x\\ \\-3y1+\dfrac{2}{3}x\\ \\y>-5+\dfrac{4}{3}x\end{array}\right.$

2. To graph both inequalities, first draw dotted lines -2x+3y=3 and 4x-3y=15 (dotted because the signs of inequalities are both without notion "or equal to"). Then choose appropriate part, substituting the coordinates of the origin:

$-2\cdot 0+3\cdot 0=0>3\ - \ \text{false}\\ \\4\cdot 0-3\cdot 0=0$

So, the origin belongs to the top part of the second inequality and to the bottom part of the first inequality. The intersection of these two regions is the solution set to the system of two inequalities (see attached diagram).
