the vertices of a triangle are P(4, 7), Q8, -1), and R(-9, 6). What are the vertices of the image reflected across the x-axis?
A. P(4, 7), Q'(8, -1), R'(-9, 6)
B. P'(-4, -7), Q'-8, 1), R'(9, -6)
C. P(-4, 7), Q'(-8, -1), R'(9, 6)
D. P'(4, -7), Q'8, 1), R'(-9, -6)

Answers

Answer 1

Answer:

D.)

Step-by-step explanation:

Reflecting an image/shape over the x axis is reflecting it over a horizontal line, so the x coordinates will stay the same and the y coordinates will be the opposite. Therefore, the answer is D. Hope this helps!

XY zand ABC are similar. If angle X is 32 degrees and angle Y is 84
degrees, find the measure of angle C.

Answers

Answer:

B

Step-by-step explanation:

A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.

Answer: B. 64 degrees

Step-by-step explanation:

∠C = 180° - (∠X + ∠Y)

∠C = 180° - (32° + 84°) = 180° - 116° = 64°

Eric made a scale drawing of the middle school. The scale he used was 1inch=5feet. If the gym is 30 inches by 20 inches in the drawing, what is the acual length and width of the gym.

Answers

Answer: 150 feet : 100 feet

Step-by-step explanation:

From the question, we are informed that the scale used by Eric was 1inch=5feet.

If the gym is 30 inches by 20 inches in the drawing, the acual length and width of the gym would be:

Length = 30 inches = 30 × 5 feet = 150 feet

Width = 20 inches = 20 × 5 feet = 100 feet

Therefore, the acual length and width of the gym would be 150 feet by 100 feet

Answer:

Answer: 150 feet : 100 feet

Step-by-step explanation:

From the question, we are informed that the scale used by Eric was 1inch=5feet.

If the gym is 30 inches by 20 inches in the drawing, the actual length and width of the gym would be:

Length = 30 inches = 30 × 5 feet = 150 feet

Width = 20 inches = 20 × 5 feet = 100 feet

Answers

Answer:

Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.

You would have to find a GCF (greatest common factor) and multiply it out of the radical.

ex.

[tex]\sqrt{6}[/tex] = 2 x 2 x 2

when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2

2[tex]\sqrt{2\\}[/tex]

so [tex]\sqrt{6}[/tex] would be closest to the positive 2 on the number line and 2 notches.

[tex]\sqrt{11}[/tex]

is an irrational number, so it might fall into 3.3 if turned into a decimal.

Option 1: $10.00 every day


Option 2: $3.00 on the first day, $3.50 on the second, $4.00 on the third, and so on, increasing by $0.50 per day.


Option 3: $0.01 on the first day, $0.02 on the second, $0.04 on the third, and so on, doubling each day.





Option 1: ($10.00 per day) :
#1 (Is this option Arithmetic, Geometric, or neither?)
#2 (Write a formula to find how much you would make on any day.)



Option 2 : (increases by $0.50 per day, day 1: $3.00)

#1 : Is this option Arithmetic, Geometric, or neither?

#2: Write a formula to find how much you would make on any day.




Option 3: (doubles each day, day 1: $0.01)

#1 : Is this option Arithmetic, Geometric, or neither?

#2: Write a formula to find how much you would make on any day.

Answers

Answer:

Option 1:

Arithmetic

f(x)=10+10xd

Option 2:

Neither

f(x)=3.00+0.50d

Option 3:

Geometric

f(x)=0.01(2)^x

Step-by-step explanation:

An arithmetic equation is one that increases by the same amount every day, a constant, straight rate. Geometric increases by the same amount everyday, doubling every day is an example of this, its linear, and is a constant rate of change.

f(x)=10+10xd means the initial 10 plus 10 every day, the d= day, so if you want to calculate a certain day, such as day 10 you replace d with the day number

f(x)=10+10x10= 110

f(x)=3.00+0.50d means initial 3.00 dollars adding 0.50 each day that passes, again, replace the d with the day number you are on.

f(x)=3.00+0.50 x 10= 8

f(x)=0.01(2)^x

the 0.01 is our starting number, the (2) represents the doubling every day, the x represents the day, and is squared.

f(x)=0.01(2)^10 = 10.24

A hiker stands on a small hill and tosses a stone. The stone then follows a path with height h above the ground at time t. The function

h(t) = - 16t2 + 16x + 32 models the stone's path. How long does it take the stone to reach its maximum height?

Answers

Answer:

At time t=0.5, the stone reaches a maximum height of h= 35.

Step-by-step explanation:

A quadratic function or function of the second degree is a polynomial function defined by:

f(x)=a*x² + b*x +c

The maximums and minimums of a function are the largest (maximum) or smallest (minimum) values ​​of a function.

The vertex of the function is a point that is part of the parabola or quadratic function that coincides with the maximum or minimum. When a> 0, the vertex of the parabola is at the bottom of it, being a minimum (that is, the parabola opens "upward"), and when a <0 the vertex is at the top , being a maximum (that is, the parable opens "downward").

h represents the value of its abscissa (value of x).

k represents the value of its ordinate (value of f (x)).

The value of h can be calculated with the formula [tex]h=-\frac{b}{2*a}[/tex]

The value of k must be obtained by substituting the value of h in the function f(x)=a*x² + b*x +c

In this case: a=-16, b=16 and c=32. As a <0 the vertex is at the top , being a maximum. So:

[tex]h=-\frac{16}{2*(-16)}=0.5[/tex]

Substituting the value of h in the function f(x)=-16*x² + 16*x +32 you get:

f(0.5)=-16*0.5² + 16*0.5 +32

f(0.5)= 35

At time t=0.5, the stone reaches a maximum height of h= 35.

The scale factor from a small triangle ABC to a large
triangle XYZ is 4. How many times larger will the
perimeter of triangle XYZ be than the perimeter of
triangle ABC?

Answers

9514 1404 393

Answer:

  c  4 times

Step-by-step explanation:

If the side lengths of the original triangle are AB, BC, and CA, then those of the dilated triangle are 4AB, 4BC, 4CA.

The sums of these are the perimeters.

  P = AB +BC +CA

  perimeter of XYZ = 4AB +4BC +4CA = 4(AB +BC +CA) = 4P

The perimeter of XYZ is 4 times the perimeter of ABC.
