a. 10°
b. 55°
C. 5°
d. 35°

Answers

Answer 1

Answer:

Answer:

$\:x=55^(\circ \:\:)$

Therefore, option 'b' is correct.

Step-by-step explanation:

Let x be the angle

tan x = 1.4281

determining the $\tan ^(-1)\left(1.4281\:\right)$

$\:\tan \:x\:=1.4281\:$

$x=\tan ^(-1)\left(1.4281\:\right)$

$\:x=55^(\circ \:\:)$

Therefore, option 'b' is correct.

Hello,

Let's say there are n sides
$P(1)=a_(1)+a_(2)+a_(3)+....+a_(n)$

$P(2)=2*a_(1)+2*a_(2)+2*a_(3)+....+2*a_(n)\n=2*(a_(1)+a_(2)+a_(3)+....+a_(n))=2*P(1)$ (Put 2 in commun factor)

How are expressions and equations different

Answers

An "equation" has a left side, a right side and an equals sign separating the sides. An "expression," by contrast, doesn't have any "sides" and is simply what the name suggests: An algebraic "expression."

Expressions have no equal sign, while equations have equal signs.

This question was on the most recent SAT Mathematics Level 2 test. If two spheres with unequal diameters intersect, what could be the intersection?a. a point
b. a circle
c. a sphere
d. a point or a sphere
e. a circle or a sphere

99 points. Please provide a detailed and explanative answer.

Answers

It could be a point or a circle.

If the two spheres are tangent, then the intersection is by definition a point.

Since the two spheres are of unequal diameter, their intersection can't be a sphere (that can only happen if the spheres are of the same diameter and at the same point, then they overlap everywhere).

Now what happens if the two spheres are drawn close to each other a random way ? Well, they will intersect along a circle [see the image attached].

If you want more explanations/..., feel free to ask.

A Circle or point is your answer
