Step-by-step explanation:

I hope you got the hang of it.

I didn't had a place to draw the verbal questions, so I just did them in my head - if you want to understand it better

I suggest that you draw those triangles

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ÷)

Describe the location of point (-3, -2, 3) in three-dimensional coordinate space.

Alja [10]

Answer:

The usual way to draw a 3-D grid can be seen below.

The positive z-axis points upwards

The positive y-axis points to the right

The positive x-axis points towards you, or to the front.

And the notation for a point in 3-D is (x, y, z)

In this case, our point is (-3, -2, 3)

Then the location of the point can be described as:

So the x-value is -3, which means that the point is 3 units behind the origin.

The y-value is -2, which means that the point is 2 units at the left of the origin

The z-value is 3, which means that the point is 3 units above the origin.

Give an example of this when adding two rationalnumbers with different signs and provide the product.

kolezko [41]

ANSWER:

$\begin{gathered} \frac{4}{5}+-\frac{8}{3}=-\frac{28}{15} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{32}{15} \end{gathered}$

STEP-BY-STEP EXPLANATION:

Rational numbers are all numbers that can be expressed as a fraction, that is, as the quotient of two whole numbers.

Therefore, an example would be:

$\begin{gathered} \frac{4}{5}\text{ and - }\frac{8}{3} \\ \text{adding} \\ \frac{4}{5}+-\frac{8}{3}=\frac{4}{5}-\frac{8}{3} \\ \frac{4}{5}-\frac{8}{3}=\frac{4\cdot3-5\cdot8}{5\cdot3}=\frac{12-40}{15}=-\frac{28}{15} \\ \text{ product} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{4\cdot8}{5\cdot3}=-\frac{32}{15} \end{gathered}$

Find all points of intersection of the given curves. (Assume 0 ≤ θ < 2π and r ≥ 0. Order your answers from smallest to larges

Aloiza [94]

Answer:

The points are (3π/4, $\frac{2 + \sqrt{2} }{2}$ ) and (7π/4, $\frac{2 - \sqrt{2} }{2}$ )

Step-by-step explanation:

Since the two equations r = 1 + cos(θ) and r = 1 − sin(θ) intersect, then

1 + cos(θ) = 1 − sin(θ)

collecting like terms

cos(θ) + sin(θ) = 1 - 1

cos(θ) + sin(θ) = 0

dividing through by cos(θ), we have

cos(θ)/cos(θ) + sin(θ)/cos(θ) = 0/cos(θ)

1 + tan(θ) = 0

tan(θ) = -1

Since tanθ is negative in both the second and fourth quadrant, we have

tan(π - θ) = 1 or tan(2π - θ) = 1

(π - θ) = tan⁻¹1 or (2π - θ) = tan⁻¹1

(π - θ) = π/4 or (2π - θ) = π/4

θ = π - π/4 = 3π/4 or θ = 2π - π/4 = 7π/4

Substituting these values into r = 1 + cos(θ), we have

r = 1 - cos(3π/4) or r = 1 - cos(7π/4)

r = 1 - (-1/√2) or r = 1 - 1/√2

r = 1 + √2/2 or r = 1 - √2/2

r = $\frac{2 + \sqrt{2} }{2}$ or r = $\frac{2 - \sqrt{2} }{2}$

So, the points are (3π/4, $\frac{2 + \sqrt{2} }{2}$ ) and (7π/4, $\frac{2 - \sqrt{2} }{2}$ )

the measure of one acute angle is twice the difference of the measure of the other acute angle and 12

Dmitrij [34]

Is there a picture to find the measure of the acute angle? Or do you want an equation to solve it? If so than it is: 2b-12=a, where b is the measure of the other acute angle and a is the measure of the acute angle where it is twice the difference of the measurment of the other acute angle and 12.
