∆ABC is reflected across the y-axis and translated 3 units up to create ∆XYZ. Select all statements that are true about ∆ABC and ∆XYZ.
Answers
Answer:
Step-by-step explanation:
Suppose A is (-3,6) when it starts out.
When A is reflected across the y axis, it takes on the opposite sign.-3 becomes + 3Nothing happens to the y value of the point from this transformationThe new point is X(3,6)Now we take the reflected point and move it three units. up
Up means increase the y value of the new point (X)The y value = 6Increase the y value by 3This makes 6 + 3 = 9So after all that X becomes (3,9)Answer:
∆ABC is congruent to ∆XYZ.
Corresponding sides of ∆ABC and ∆XYZ are not congruent.
Corresponding angles of ∆ABC and ∆XYZ are congruent.

Consider the periodic function obtained by replicating the following function over intervals of length 10:5(x)=x² ; 0
Answers
To obtain the periodic function by replicating this over intervals of length 10, we can write the extended function as f(x) = 5((x mod 10)^2) and as the function 5(x) = x² is even, its periodic extension f(x) is also even, meaning it is symmetric about the y-axis.
Since the period is 10, we can write the extended function as:
f(x) = 5(\((x mod 10)^2\)),
where "mod" denotes the modulo operator, which gives the remainder after division.
In other words, for any value of x, we first find its remainder when divided by 10 (i.e., the value of x "wrapped" around the interval [0,10]). Then we evaluate the original function 5(x) = x² at this wrapped value.
For example, if x = 8, then its wrapped value is 8 mod 10 = 8, so we have:
f(8) = 5((\(8)^2\)) = 5(64) = 320.
Similarly, if x = 13, then its wrapped value is 13 mod 10 = 3, so we have:
f(13) = 5(\((3)^2\)) = 5(9) = 45.

A square based pyramid has a surface area of 111.6 in2. The sides of the base
of the pyramid measure 4 inches. What is the slant height of the figure?
Answers
Answer:
11.95 in
Step-by-step explanation:
We can find the slant height of a square-based pyramid by solving the area formula for the unknown value.
__
The formula for the area of a square-based pyramid can be written ...
A = s(s +2h)
where s is the side of the square base, and h is the slant height.
Filling in the given values, we can solve for h:
111.6 = 4(4 +2h)
27.9 = 4 +2h . . . . . divide by 4
13.95 = 2 +h . . . . . divide by 2
11.95 = h . . . . . . . . subtract 2
The slant height of the figure is 11.95 inches.

What is the inverse of a function?
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1."

Functions are shown in the picture.
To find the inverse of a function plug in the place of f(x)→x and x→f(x) ⁻¹
f(x) ⁻¹ = 3(x + 17)/2
Similarly,
f(x) = x - 10
f(x) ⁻¹ = x + 10
f(x) = ∛2x
f(x) ⁻¹ = x³/2

What is the slope of -1/2x+2y=7
Answers
Answer: 1/4
Step-by-step explanation:
First, we have to rearrange the given equation so that it results in a y=mx+b equation. To do this we can add -1/2x on both sides to remove it from the left side.
(+1/2x)-1/2x + 2y = 7(+1/2x)
2y = 1/2x +7
Now we can divide by 2 on both sides to isolate the y.
(2y)/2 = (1/2x +7)/2
y = 1/4x + 3.5
The slope is 1/4 :)

Lying outside the cirlce.
Step-by-step explanation:
Find the center and radius of the circle form the given equation.(x - h)² + (y - k)²= r²
Here, (h ,k) is the center of the circle and r is the radius.
(x + 10)² + (y - 1)² = 25
r² = 25
r = √25
r = 5 units
Now, substitute the point (-20 , 6) in the equation of the circle.LHS = (-20 + 10)² + (6 - 1)²
= (-10)² + 5²
= 100+25
= 125 > 25
As 125 is greater than 25, the point (-20 ,6 ) is lying outside the circle.

To find the sum of fractions, we need to have a common denominator. In this case, the common denominator is 7 * (-11) * 21 * 22 = -230,514.
Now we can add the fractions:
\(\displaystyle \frac{3}{7} + \frac{6}{-11} + \frac{-8}{21} + \frac{5}{22} = \frac{3 \cdot (-11) \cdot 21 \cdot 22}{7 \cdot (-11) \cdot 21 \cdot 22} + \frac{6 \cdot 7 \cdot (-21) \cdot 22}{-11 \cdot 7 \cdot (-21) \cdot 22} + \frac{-8 \cdot 7 \cdot (-11) \cdot 22}{21 \cdot 7 \cdot (-11) \cdot 22} + \frac{5 \cdot 7 \cdot (-11) \cdot 21}{22 \cdot 7 \cdot (-11) \cdot 21}\)
Simplifying the fractions:
\(\displaystyle \frac{-1386}{-230514} + \frac{1848}{-230514} + \frac{-1936}{-230514} + \frac{1155}{-230514}\)
Combining the fractions:
\(\displaystyle \frac{-1386 + 1848 - 1936 + 1155}{-230514}\)
Simplifying the numerator:
\(\displaystyle \frac{-319}{-230514}\)
Dividing the numerator and denominator:
\(\displaystyle \frac{319}{230514}\)
Therefore, the sum of the fractions 3/7, 6/-11, -8/21, and 5/22 is 319/230514.

Which segment is an angle bisector of triangle ABC?
A. BX
B. SR
C. BF
D. AR
Answers
Answer: A. BX
Step-by-step explanation:
BX is the only line that bisects an angle. BX bisects angle B. Therefore, BX is an angle bisector.
SR is an altitude
BF is a segment of BC
AR is a chord
BX is the angle bisector of triangle ABC.
Angle bisecting refers to dividing an angle into two equal or congruent parts. The line or ray that divides the angle into two equal parts is called the angle bisector. It always cuts the angle into two angles of equal measure.
The properties of an angle bisector are :
It divides the angle into two equal angles, i.e., both resulting angles have the same measurement.
It is equidistant from the two sides of the angle, i.e., any point on the angle bisector is equidistant from the sides of the angle.
If a point lies on the angle bisector, it is equidistant from the two sides of the angle.
So, looking at the properties we can say that BX is the angle bisector of triangle ABC.

The value of θ is approximately equal to 0.92729522.
What do you mean by sine?The sine function is a basic trigonometric function used in mathematics to describe the relationship between the lengths of sides of a right triangle and its angles. The sine function is denoted by the symbol sin and is defined as the ratio of the side opposite a given angle to the hypotenuse of the triangle.
The sine function is periodic, meaning that it repeats its values over a certain interval, and its values range from -1 to 1.
If sin (θ)=8/17, where 0 < θ < pi/2 and cos (θ)=5/13, then θ can be found using the inverse sine function.
θ = sin⁻¹ (8/17) = sin⁻¹ (5/13) = arctan(8/5).
So, the value of θ is approximately equal to 0.92729522.

Determine algebraically whether the function is even, odd, or neither?
f(x)=3 x 3+5
Answers
The function f(x) = 3x³ + 5 is neither even nor odd. To determine whether a function is even or odd, you need to check how the function behaves when x is replaced with -x.
To determine whether the given function is even, odd, or neither, we need to check the following conditions:
Even function: If f(-x) = f(x) for all x in the domain of f, then the function is even.
Odd function: If f(-x) = -f(x) for all x in the domain of f, then the function is odd.
Let's check these conditions for the given function:
f(x) = 3x³ + 5
f(-x) = 3(-x)³ + 5 = -3x³ + 5
f(x) = 3x³ + 5
Since f(-x) is not equal to f(x), the function is not even.
f(-x) = 3(-x)^3 + 5 = -3x^3 + 5
-f(x) = -(3x^3 + 5) = -3x^3 - 5
Since f(-x) is not equal to -f(x), the function is not odd.
Therefore, the given function is neither even nor odd.

Answers
Answer:
B. y = 10(2)^x
Step-by-step explanation:
y = ab^x
to find "b" divide the function at x = 3 by the function at x = 2
80 = ab^3
——————
40 = ab^2
This results in
2 = b
to find "a" plug pickany value of x
using x = 2
40 = a(2²)
40 = a(4)
a = 10
With a = 10 and b = 2 the exponential function y = ab^x is
y = 10(2)^x

Because K is on the left side of 0, it is negative. Therefore, the x-coordinate must be negative (the horizontal axis), and so we can rule out choices 3 and 4. The y-coordinate (the vertical axis) has to be 5/8. This is because 1/2 can be rewritten as 4/8, and 5/8 is exactly one unit above that. 3/4 does not work because K is too close to 1/2 to be 3/4, and 4/4 would not be able to reach one (with the set interval). Therefore, it is (-1/4, 5/8).
