Plsssssssss Help!!!What Is The Distance Between Points A(-3,4) And B(1,-2)? Round To The Nearest 10th

Answers

Answer 1

Answer:

D. 7.2

Step-by-step explanation:

6^2 +4^2 = c^2

sqrt 36 + sqrt 16 = c^2

c^2 = sqrt 52  =  7.21110255 = 7.2

Answer 2

Answer:

Step-by-step explanation:

Step-by-step explanation:

Distance between two points is given by

|xy|=√(x2-x1)² +(y2-y1)²

So putting the points A(-3,4) B(1,-2) into the equation

|AB|= √(4--3)²+(-2-1)²

=√(7)²+(-3)²

= √49+9

= √58

=7.2

Answer:

753.982236862

Step-by-step explanation:

1) Cut Cylinder in half, perpendicular to the circle face. Effectively making a rectangle face. The Pencil diagnolly reaching from the top corner to the bottom corner act like a divider which splits the rectangle into 2 triangles. Which allows for us to use Pythagorem theorem.

pythagorean theorem: [tex]c^2=a^2+b^2}[/tex]

The Pencil is 17cms long. So [tex]17^{2}[/tex]=[tex]{a^2+b^2}[/tex]

the height is 15cms long. So [tex]17^{2}[/tex]=[tex]15^2+b^2}[/tex]

We need to Solve for B, so we will subtract A from C since C is the longest side on the Triangle.

289-225=[tex]\sqrt{64\\}[/tex] = 8

b=8

b is the diameter of the Cylinder

Since we need the Radius squared for Cylinder we divide the Diameter in half. 8/2=4

4X4=16

Next we wil figure out the Volume,

[tex]\pi *4^{2} *15[/tex]=753.982236862

the answer is 753.98

Line d is parallel to line c in the figure below.

Parallel lines d and c are intersected by lines q and p to form 2 triangles. At lines d and p, the angle is 2, at d and q, the angle is 1, and at q and p the angle is 3. At lines c and q, the angle is 4, at p and c, the angle is 5, and the third angle is 6.

Which statements about the figure are true? Select three options.
Vertical angles prove that Angle 2 is congruent to angle 5.
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.
In the two similar triangles, Angle 2 and Angle 4 are corresponding angles.
The triangles are similar because corresponding sides are congruent.

option B

Step-by-step explanation:

-2(4 - 3x) + (5x - 2)=

-8+6x+5x-2= 11x -10

-8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is -2(4 - 3x) + (5x - 2)

We have to find the equivalent expression

x is the variable in the expression

Equivalent expressions are expressions that work the same even though they look different.

Let us apply distributive property

-8+6x+5x-2

Combine the like terms

11x-10

Hence, -8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)
