Does anyone know how to solve this?
MrRissso [65]

9514 1404 393

Answer:

Step-by-step explanation:

The tangent of the angle can be found using the identity for the tangent of the difference of angles.

  tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))

The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.

  tan(α) = -2/3

  tan(β) = 4/7

  tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))

  = (-14-12)/(21 -8) = -26/13 = -2

Then the magnitude of the angle between the vectors is ...

  arctan(2) ≈ 63.43°

How would I graph this?
elena55 [62]

y\leq 2x-5

↝ x-intercept

2x-5=0\\2x=5\\x=\frac{5}{2}

↝ y-intercept

y = -5

↝ y\leq 2x-5 means that the shade/area is below the graph as shown in the first picture.

y\leq -\frac{1}{2}x-3

↝ x-intercept

-\frac{1}{2}x-3=0\\-x-6=0\\-x=6\\x=-6

↝ y-intercept

y = -3

↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.

First picture is first inequality

Second picture is second inequality.

To find the area of a circle with a diameter of 18.
Serga [27]

\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the areas.

Since we know that, radius = diameter /2

here, => d = 2r ,

hence we use the formula as,

A = πr^2 ,

here option d.) is correct.
