Answer:

Step-by-step explanation:

We have to find the values of the given trigonometric ratios at the angle indicated. Thus,

(A) The given trigonometric function is:

cos270^{\circ}

Since, the function lies in Quadrant III, therefore the value of the function will be negative.

Also, cos270^{\circ}=-(0)=0

(B) The given trigonometric function is:

sin270^{\circ}

Since, the function lies in Quadrant III, therefore the value of the function will be negative.

Also, sin270^{\circ}=-1

(C) The given trigonometric function is:

tan270^{\circ}

Since, the function lies in Quadrant III, therefore the value of the function will be negative.

Also, tan270^{\circ}=undefined

(D) The given function is:

cos0^{\circ}

Since, the function lies in Quadrant I, therefore the value of the function will be positive.

Also,  cos0^{\circ}=1

(E) The given function is:

sin0^{\circ}

Since, the function lies in Quadrant I, therefore the value of the function will be positive.

Also,  sin0^{\circ}=0

(F) The given function is:

tan0^{\circ}

Since, the function lies in Quadrant I, therefore the value of the function will be positive.

Also,  tan0^{\circ}=0

16) (1 Point) : Solve the equation
Marat540 [252]

Answer:

(B)

4 +/- 3 sqrt(2) or 4+3sqrt(2) and 4-3sqrt(2)

Step-by-step explanation:

4(c-4)^2=72

4(c-4)(c-4)=72

foil the parenthesis (first, outside, inside, last)

4(c^2 -4c -4c +16)=72

4(c^2-8c+16)=72

divide each side by 4

c^2-8c+16=18

subtract 18 from both sides

c^2-8c-2

use quadratic formula

((-b +/- sqrt((-b^2)-4ac)))/2a

((-(-8)+/-sqrt((-8)^2-4(1)(-2)))/2(1))

(8+/-sqrt(64-(-8)))/2

(8+/-sqrt(64+8))/2

(8+/-sqrt(72))/2

(8+/-sqrt(36 * 2))/2

(8+/-6sqrt(2))/2

4+/-3sqrt(2)

or 4+3sqrt(2) and 4-3sqrt(2)

Suppose a principal amount of $2079 were invested into a simple interest account that pays an annual rate of 2.31% then the amou
Anna35 [415]

Answer:

The amount of interest earned at the end of 14 years would be $672.3486

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this problem, we have that:

P = 2079, I = 0.0231, t = 14

So

E = 2079*0.0231*14 = 672.3486

The amount of interest earned at the end of 14 years would be $672.3486

5x+11=-3x+35 i need help solve for x
vaieri [72.5K]

Answer:

x = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

5x + 11 = -3x +35

Add 3x to both sides.

5x + 11 + 3x = -3x + 35 + 3x

8x + 11 = 35

Subtract 11 from both sides.

8x + 11 - 11 = 35 - 11

8x = 24

Divide both sides by 8.

\frac{8x}{8} = \frac{24}{8}

x = 3

So therefore, that is how you found your answer: x = 3
