How do you input this into the calculator

Answers

Answer 1

Answer: $\sin\theta=(b)/(c)\ therefore\ b=c\cdot\sin\theta\n\n\cos\theta=(a)/(c)\ therefore\ a=c\cdot\cos\theta$

$b=32\cdot\sin55^o=\sin55^o\cdot32\n\na=32\cdot\cos55^o=\cos55^o\cdot32$

Answers

Answer:

C. 1/10

Step-by-step explanation:

yes, it is in the thousands place, but it's comparing the 7 in the ten thousands place to the 7 in the thousandths place. If it said the 7 in the ten thousands is _____ the value of the 7 in the thousands place, the answer would be A. 10x.

10,000/10=1,000 so the answer is C. 1/10.

The lines 3y-x=3 and y+3=3(x-1) are

Answers

lets change the form of the equations to the canonical line equation form:
y = mx + b

3y - x = 3
y = (1/3)x + 1

y + 3 = 3(x - 1)
y = 3x - 6

Solve the system using elimination. Write the solution as an ordered pair. (1 point) SHOW YOUR WORK FOR FULL CREDIT! (2 points)13x + y = 15
-9x - 3y = -15

Answers

Answer: (1,2)

Step-by-step explanation:

You must:

- Multiply the first equation by 3.

- Add both equations.

- Solve for the variable left. In this case will be x.

Then:

$\left \{ {{39x +3y = 45} \atop {-9x - 3y = -15}} \right.\n------\n 30x=30\nx=1$

Substitute x=1 into any of the original equtions and solve for y:

$13(1)+y=15\ny=2$

The solution is: (1,2)

Answer:

The solution of the system of equation is (1 , 2)

Step-by-step explanation:

The system of equation is:

* 13x + y = 15 ⇒ (1)

* -9x - 3y = -15 ⇒ (2)

- By using elimination ⇒ we must make on of the

two variables in the two equations has the same value

with different sign

- So we will multiply equation (1) by 3 to eliminate y

∴ 3(13x) + 3(y) = 3(15)

∴ 39x + 3y = 45 ⇒ (3)

- Now add (2) and (3)

∴ 39x + -9x = 45 + -15

∴ 30x = 30 ⇒ ÷ 30 both sides

∴ x = 1

- Substitute the value of x in equation (1) or (2)

- Lets use (1)

∴ 13(1) + y = 15

∴ 13 + y = 15 ⇒ subtract 13 from both sides

∴ y = 15 - 13

∴ y = 2

∴ The solution of the system of equation is (1 , 2)
