Answer:Answer is A

Step-by-step explanation:

Correct option is

6x+2y=15

Given line is y=−3x+4

This is slope intercept form of a line where slope of line is −3.

Since, two lines are parallel When their slopes are equal.

Slope of line is 6x+2y=15

⇒2y=−6x+15

⇒y=−3x+

is equal to −3

Option A is correct.

Round each fraction to the nearest half and find the estimate.

erastova [34]

Answer: The result is one half ( $\frac{1}{2}$ )

Step-by-step explanation:

We have the following expression:

$\frac{2}{6}+\frac{1}{6}$

Since both fractions have the same denominator, we can just add both numerators and keep the denominator:

$\frac{2+1}{6}=\frac{3}{6}$

Dividing numerator and denominator by $3$ :

$\frac{\frac{3}{3}}{\frac{6}{3}}=\frac{1}{2}$ This is the result

Identify the surface whose equation is given. rho2(sin2(φ) sin2(θ) + cos2(φ)) = 49

Paha777 [63]

Answer:

The surface is a cylindrical surface with radius 7 units

Step-by-step explanation:

The equation is properly written as:

$\rho^{2} (sin^{2} \phi sin^{2} \theta + cos^{2} \phi) = 49$

The above equation takes the form $y^{2} + z^{2} = r^{2}$

Where $y^{2} = \rho^{2} sin^{2} \phi sin^{2} \theta$

$y = \rho sin \phi sin \theta$

and $z^{2} = \rho^{2}cos^{2} \phi$

$z = \rho cos \phi$

$r^{2} = 49$

r = 7 units

The surface is a cylindrical surface with radius 7 units

How many times does the line y=-6 intersect with the circle x^2+y^2=36?

HACTEHA [7]

Answer:

a) The line intersects with the circle once.

b) Tangent

Step-by-step explanation:

We are given the following equation for the circle:

$x^2 + y^2 = 36$

How many times does the line y=-6 intersect with the circle?

We have to find the values of x when $y = -6$

$x^2 + y^2 = 36$

$x^2 + (-6)^2 = 36$

$x^2 + 36 = 36$

$x^2 = 0$

$x = 0$

Since the line intersects the circle at one point, it is tangent to the circle.

The line intersects with the circle once.
