The diameter of a circle is 10 millimeters. The circumference of the circle is 62.8 millimeters. True False

Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.

If quadrilateral A B C D rotates 90° counterclockwise about the origin, what are the coordinates of A′ in quadrilateral A′B′C′D′ ?

If this is all the information you have I can explain it like this.

Your original coordinates are written in the form (x,y).
If you rotate the quadrilateral about the origin 90 degrees, it will be (-y,x).

For example, if the original coordinates for A is (4,6), then A'  is (-6,4).

A fountain on a lake sprays water in a parabolic arch modeled by the equation y = −0.4x2 + 3x, where y is the height in feet and x is the horizontal distance. A beam of light is passed through the fountain to create a rainbow effect. If the beam is directed at an angle modeled by the equation -2.2x + 4.9y = 8.18, at what distance from the ground will the beam first touch the water spray?

To answer this question, we are given with two equations y = −0.4x^2 + 3x which decribes the parabolic arched water of the lake and -2.2x + 4.9y = 8.18 which models the direction of the beam. To find the distance from the ground, y  which the beam first touch that water spray, we get the expression of the first equation in terms of y and substitute to the second equation. x is equal to 0.743 meters y is equal to 2.0 meters. Answer is 2 meters.

You’re given three angle measurements of 30°, 70°, and 80°. How many triangles can you construct using these measurements?

Answer:

Infinite similar triangles

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

In a triangle the sum of its internal angles must be equal to 180 degrees

In this problem

The sum of the internal angles is equal to 180 degrees

so

By the sum of the internal angles, we can construct a triangle

but

By the length of the sides keeping the same internal angles, we can construct infinite similar triangles.

A square is inscribed in a circle that has a radius of 2√2 inches. What is the length of the side of the square?

When a square (or any rectangle) is inscribed in a circle, the diagonal
of the square (or rectangle) is a diameter of the circle.

Diagonal of this square = diameter = 2 x radius = 4√2 inches.

But the diagonal of a square is the hypotenuse of the right triangle that's
formed by cutting the square in half corner-to-corner.

So  (diagonal)²  =  (side)²  +  (side)²

           2 (side)² = (diameter)²

           2 (side)²  =  (4√2)²

           2 (side)²  =  16 x 2 = 32

              (side)²  =  16

               side  =    4 inches

The first incorrect step would be step number three since when solving Absolute-Value Equations, when you isolate the Absolute-Value bars and the terms inside of it, the next step should be to make two equations: one that equals the original number given on the right side of the equal sign and one that is the opposite of the number on the equal sign. For example, in this case, Step three should have turned out more like this:

|2x - 3| = 3

2x - 3 = 3 AND  2x - 3 = -3

An isosceles right triangle has leg lengths of 4 centimeters. What is the length of the altitude drawn from the right angle to the hypotenuse? 2 cm cm 4 cm cm

See the picture attached to better understand the problem

we know that
AB=4cm \\ AC=4 cm

in the right triangle ADB
angle DBA=angle DAB \\ =45 degrees
cos (DAB)= \frac{AD}{AB}
where
AD is the adjacent side angle DAB (altitude)
AB is the hypotenuse triangle ADB 
Angle DAB=45°
so
solve for AD
AD=AB*cos (45)
AD=4* \frac{ \sqrt{2}}{2} \\ AD=2 \sqrt{2} cm

therefore

the answer is 
the length of the altitude is 2 \sqrt{2} cm

Which phrase best describes the translation from the graph y = 6x2 to the graph of y = 6(x + 1)2? 6 unit left 6 unit right 1 unit left 1 unit right x

Answer:

Option C is correct.

Step-by-step explanation:

Given Graph : y=6x^2

Translated Graph : y=6(x+1)^2

We have to find phrase that best describes the translation.

Since Initial graph is of a parabola with vertex ( 0 , 0 )

And translated graph is also of parabola but with vertex ( -1 , 0 )

As the vertex of the graph shifted 1 unit to the left hand side.

Therefore, Option C is correct.

Which quadrilateral will always have 4-fold reflectional symmetry? trapezoid rhombus square rectangle

When a geometric figure is folded about a line of symmetry, the two halves match up so if you have copies of the quadrilaterals (you can test lines of symmetry by folding). 

Since a square has four equal sides and angles, it will have reflectional symmetries across four axes. Square can be folded in half over either diagonal, the horizontal segment which cuts the square in half, or the vertical segment which cuts the square in half. So the square has four lines of symmetry. 

The rectangle has only two, as it can be folded in half horizontally or vertically (the rectangle's axes go through the midpoints of the opposite sides).
 
The rhombus has only two, as it can be folded in half horizontally or vertically ( the rhombus' axes go through the opposite vertices).

 The isosceles trapezoid has one set of non-congruent, parallel sides, and one set of congruent sides that are not parallel to each other. This figure will only have one reflectional line of symmetry across the axis, which runs through the midpoints of the parallel sides, and is perpendicular to them.
