a.) y = | x - 2|
b.) y = | x + 2|
c.) y = | x | + 2
d.) y = | x | - 2
Answer:
d
Step-by-step explanation:
up and down is outside of the x stuff so its c or d
and c is moving it up
d is moving it down
Answer:
d) y = | x | - 2
Step-by-step explanation:
In order to translate a graph downward 2 units ,we subtract 2 from the original function.
therefore,
If the Original function is y = |x|
Then the Function of the translated graph is y = | x | - 2
The floor of a rectangular room measures 5m by 4m and the ceiling is 3m from the floor. An ant is at the top of a corner of the room and crawls to the opposite bottom corner of the room. Find the shortest distance it can travel. (Cannot do its diagonal distance)
Answer:
12 m
Step-by-step explanation:
Well, imagine you got this nice room. How can it reach the other corner? It has to go along the 3 dimensions. So the shortest path would be: 5 + 4 + 3 12m
Answer:
3 + √(41) = 9.4 m (nearest tenth)
Step-by-step explanation:
The room can be modeled as a rectangular prism with:
width = 4 mlength = 5 mheight = 3 mIf the ant is at the top of a corner of a room and crawls to the opposite bottom corner of the room, the shortest distance will be to travel down one vertical edge of the room then to travel the diagonal of the floor of the room (or to travel the diagonal of the ceiling and then one vertical edge).
Vertical edge = height of room = 3m
The diagonal of the floor (or ceiling) is the hypotenuse of a right triangle with legs of the width and length. Therefore, to find the diagonal, use Pythagoras Theorem.
Pythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangleGiven:
a = width = 4 mb = length = 5 mc = diagonalSubstitute the given values into the formula and solve for c:
[tex]\implies 4^2+5^2=c^2[/tex]
[tex]\implies c^2=41[/tex]
[tex]\implies c=\sqrt{41}[/tex]
Therefore, the shortest distance the ant can travel is:
⇒ 3 + √(41) = 9.4 m (nearest tenth)

Determine if diverges, converges, or converges conditionally.
By the alternating series test, this series converges: for [tex]k\in\Bbb N[/tex],
[tex]\dfrac{k^5+1}{k^6+11}[/tex]
is a positive, decreasing sequence that converges to 0.
However,
[tex]\displaystyle \sum_{k=2}^\infty \left| (-1)^{k+1} \frac{k^5+1}{k^6+11} \right| = \sum_{k=2}^\infty \frac{k^5+1}{k^6+11} \approx \sum_{k=2}^\infty \frac1k[/tex]
is a divergent series by comparison to the harmonic series.
So the given series is conditionally convergent.
The given series is conditionally convergent. This can be obtained by using alternating series test first and then comparing the series to the harmonic series.
Determine if diverges, converges, or converges conditionally:Initially we need to know what Absolute convergence and Conditional convergence,
If [tex]\sum|a_{n} |[/tex] → converges, and [tex]\sum a_{n}[/tex] → converges, then the series is Absolute convergence
If [tex]\sum|a_{n} |[/tex] → diverges, and [tex]\sum a_{n}[/tex] → converges, then the series is Conditional convergence
First use alternating series test,
[tex]\lim_{k \to \infty} \frac{k^{5} +1}{k^{6}+11 }[/tex] = [tex]\lim_{n \to \infty} \frac{5}{6k}[/tex] = 0,
The series is a positive, decreasing sequence that converges to 0.
Next by comparing the series to harmonic series,
[tex]\sum^{\infty} _{k=2}|(-1)^{k+1} \frac{k^{5} +1}{k^{6}+11 }|=\sum^{\infty} _{k=2}\frac{k^{5} +1}{k^{6}+11 }[/tex] ≈ [tex]\sum^{\infty} _{k=2}\frac{1}{k}[/tex] = 0
This implies that the series is divergent by comparison to the harmonic series.
First we got that the series is converging and then we got the series is divergent. Therefore the series is conditionally convergent.
[tex]\sum|a_{n} |[/tex] → diverges, and [tex]\sum a_{n}[/tex] → converges, then the series is Conditional convergence.
Hence the given series is conditionally convergent.

The rotation of the triangle that's illustrated will be a rotation of 90°.
How to illustrate the information?It should be noted that transformation is a general term for 4 specific ways that can be used to manipulate the shape and the position of a point, line, or a geometric figure. In such a case, the original shape of the object is called the pre-Image while the final shape and the position of the object is simply the image under transformation.
There are typically four common types of transformations and they're translation, rotation, reflection, as well as dilation. It should be noted that rotation about simply illustrates the transformation that takes place regarding the triangle.
For rotation, the shape rotates or turns the pre-image around the axis and there'll be no change in the size or shape of the object.
Here, the counterclockwise rotation was illustrated in the triangle ABC. Therefore, the rotation of the triangle that's illustrated will be a rotation of 90°.

c. x= [tex]\sqrt{136}[/tex]cm or 11.66cm, y=[tex]\sqrt{191}[/tex]cm or 13.82cm
Step-by-step explanation:
a. You have to find the length of the other two sides of the triangle using the information already given. The first side is 6cm and the other is 12-9=4cm. Because it's a right-angled triangle you can use pythagoras
[tex]c^2=a^2+b^2\\x^2=6^2+4^2\\x^2=36+16\\x^2=52\\x=\sqrt{52}cm \\x=7.21cm[/tex]
b. You can use pythagoras again because it's a right-angle triangle
[tex]x^{2} =7^2+11^2\\x^2=170\\x=\sqrt{170} cm\\ = 13.04cm[/tex]
c. In this question you have to find x and y. We need to find x first using pythagoras
[tex]x^2=6^2+10^2\\x^2=136\\x=\sqrt{136}cm \\=11.66cm[/tex]
Now that we've found x we can find y using pythagoras but instead of find c, we will find another side
[tex]c^2=a^2+b^2\\19^2=\sqrt{170} ^2 + b^2\\361=170+b^2\\361-170=170+b^2-170\\191=b^2\\b=\sqrt{191}cm \\=13.82cm[/tex]

There are 360 girls and 135 boys in a school. What is the ratio of girls to boys expressed in the lowest terms?
Answer: 8:3
Step-by-step explanation:
360:135
We can simplify both, dividing both of them by a common divisor (45)
360/45= 8
135/45= 3
The ratio in lowest terms is 8:3
the ratio of girls to boys in the school, expressed in the lowest terms, is 8:3.
To find the ratio of girls to boys in the school, we divide the number of girls by the number of boys.
Ratio of girls to boys = Number of girls / Number of boys
Ratio of girls to boys = 360 / 135
To express the ratio in the lowest terms, we can simplify the fraction by finding the greatest common divisor (GCD) of 360 and 135 and then dividing both the numerator and denominator by the GCD.
The GCD of 360 and 135 is 45.
Ratio of girls to boys = (360 / 45) / (135 / 45)
Ratio of girls to boys = 8 / 3
So, the ratio of girls to boys in the school, expressed in the lowest terms, is 8:3. This means that there are 8 girls for every 3 boys in the school.

Find the smallest evan number that contains every digit once
Answer:
The smallest even number that contains every digit once is 1023456798.============================
Conditions we need to meet:
Use every digit once,Even number,Smallest possible number.To get the smallest number we'd use all 10 digits in the ascending order:
0123456789Here we can't have zero in the beginning as the number becomes 9-digit.
So swapping zero with the closest digit, 1.
Our number should be even, so we should swap 9 with one even digit.
Again it should be the closest one to 9, so it is 8.
We get the following number as a result:
1023456798To test you may swap digits, any number you get will be greater than this number.

Answer:
a) 20
Step-by-step explanation:
when we have an exponent of an exponent, we simply multiply them for the overall exponent.
so, we actually have
a^((1/4)×12) × b^((1/3)×12) = a³b⁴ = 5000
let's find the prime factors of 5000 :
5000 ÷ 2 = 2500
2500 ÷ 2 = 1250
1250 ÷ 2 = 625
625 ÷ 3 no
625 ÷ 5 = 125
125 ÷ 5 = 25
25 ÷ 5 = 5
5 ÷ 5 = 1
so,
5000 = 2³ × 5⁴
so, a = 2, b = 5
