Wich of the following will be the coordinate of the vertices of triangle A'B'C'?
Answers
You have to translate the triangle ABC using the translation rule:
(x,y) → (x-1,y+2)
This rule indicates that the triangle will be translated 1 unit left and 2 units up. To determine the coordinates of each vertex after the translation, you have to subtract 1 to the x-coordinate of each point and add 2 to the y-coordinate.
Original → Translation
A(6,1) → A'(6-1,1+2) = A'(5,3)
B(1,7) → B'(1-1,7+2) = B'(0,9)
C(-3,-2) → C'(-3-1,-2+2) = C'(-4,0)
The coordinates of the vertices of triangle A'B'C' will be
A'(5,3)
B'(0,9)
C'(-4,0)
The correct option is C.

b) The sum of the given number and its opposite will be 7.928.
What is an irrational number?It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
The given number is as,
3, 7.5, and -2(2/3)
a)
The opposite number is obtained as 1 by dividing the given number,
⇒ 1 / 3 = 0.33
⇒ 1 / 7.5 = 0.133
⇒ 1 / -2(2/3) = -0.375
b)
The sum of the given number and its opposite is,
= 3+0.33 + 7.5 + 0.133+ (-2(2/3) ) + (-0.375)
= 7.928

The maximum safe incline for a ramp is8.5 degrees. Is this ramp safe? If not, provide dimensions thatwould make the ramp safe.
Answers
Ok, so:
Let me draw the situation here below:
Ok, let's find the angle first:
For this, we shall make use of the trigonometric functions:
In this case, the most useful function which could help us to solve this problem is tan(x). This function relations the opposite side of the angle and its adjacent side, like this:
tan(x) = opposite side / adjacent side
So, if we replace the values:
tan(x) = 15/95
tan(x) = 0,15789474
To find x, we could use the inverse function of tan(x). This one is called arctan(x).
So, arctan(tan(x)) = arctan(0,15789474)
And this is:
x = 8.97 degrees
Now, we can affirm that the angle is 8.97 degrees, which is bigger than 8.5 degrees.
Now, what should be the length of the bottom for the ramp to be safe?
Let me draw the situation:
We know that the ramp is safe if the maximum safe incline is 8.5°. So, what should be the value of x for this occurs?
We use the trigonometric function tan(x) again.
tan(8.5°) = 15/x
Remember that tan(8.5°) is a number
Then, x = 15/tan(8.5°), and this is 100.36
So, we conclude that the lenght of the bottom should be at least, 100.36
You drive 3 hours to reach the waterpark. Driving home along the same route, you increase your

how fast you were driving to the waterpark.
Answers
The initial speed to the waterpark is 40 miles/hr.
The return speed is 60 miles/hr.
How to find the speed?
Given,
t = 3hr
Return speed = s +20m
Return time = 3 -1 = 2hrs
Solution:
s = d/t
s = d/3
d = 3s----1
s + 20 = d/t - 1
s + 20 = d/3-1
s + 20 = d/2
2s + 40 = d------2
Equating equations 1 and 2,
3s = 2s + 40
s = 40 miles/hr
The initial speed to the waterpark is 40 miles/hr.
Return speed = s +20

a woman can hike 2mph faster down a trail to Archuletta Lake then she can on the return trip uphill. it takes her 2 hours to get to the lake and 4 hours to return. what is her speed hacking down to the late?
Answers
Answer:
4 mph
Explanation :
Let us call x, the woman speed as she goes uphill
Now, we know that it took the woman 2 hours to go uphill; therefore, the distance covered is
4* (x)
shortly afterwards, when the woman returns she is walking at x + 2 mph; therefore, the distance she covers is
D = 4 (x +2 )
Since the uphill and the downhill distances ar the same, we have
4x = 2 (x +2 )
4x = 2x + 4
x = 2
Hence, going to the hill, the woman speed is 2 miles per goo

Find (g ◦ h) (x)
Answers
Answer:
(g ◦ h) (x) = 16x² + 12x -4
Step-by-step explanation:
We have
g(x) = x² − 5x
h(x)= 4x + 4
(g ◦ h) (x) = g(h(x))
h(x) = 4x + 4
g(h(x)) = g(4x + 4)
= (4x + 4)² - 5(4x+4) //substitute 4x + 4 wherever there is an s-term in
(4x + 4)² = 16x² + 32x + 16
5(4x + 4) = 20x + 20
(4x + 4)² - 5(4x+4) = 16x² + 32x + 16 -(20x + 20)
= 16x² + 32x + 16 - 20x - 20
= 16x² +(32x - 20x) + (16-20)
= 16x² + 12x -4

What is a parallelogram?A parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given that parallelogram ABCD, has m∠ABC = 135° and the length of diagonal AC is 41 units.
The measure of length of side AD is 35 units and length of side AB is 7 units.
WE know that the opposite side of a parallelogram are same. Thus,
The length of segment CD = AB = 7 units.
Also, the length of diagonal AC = 41 units. Then;
The length of segment AE = 1/2 AC = 41/2 = 20.5 units.
Therefore, m∠BCD + m∠ABC = 180
m∠BCD + 135 = 180
m∠BCD = 180 - 135
m∠BCD = 45 degrees.
Hence, The length of segment CD is 7 units. The length of segment AE is 20.5 units. The m∠BCD is 45 degrees.

The area of a rectangular pyramid is equal to the sum of the areas of the sides and faces of the rectangular pyramid. A quadrilateral pyramid is a three-dimensional shape with only a rectangular base and triangles on either side of the base.
The area of the base of the rectangle is calculated by multiplying the length of the rectangle by the width of the rectangle.
The area of a rectangle with a pyramidal formula is determined by observing the width, length, and height of the base,

The area of a sector of a circumference is given by the following formula:
[tex]A=\frac{\theta r^2}{2}[/tex]Where r is the radius of the circumference, and θ is the angle of the sector in radians.
The radius is already known: 15cm.
We need to estimate the angle of the shaded region. The shaded region and the sector whose angle is 72° form together a 180° angle. (This is according to the figure. That is not said in an explicit way but we will need to assume that since there is not enough information to calculate the area if it is otherwise.)
Then, the angle of the shaded area, plus 72° is 180°:
[tex]\begin{gathered} \theta+72^o=180^o \\ \\ \theta=180^o-72^o \\ \\ \theta=108^o \end{gathered}[/tex]Now, before applying the formula we need to express the angle in radians. Recalling that 180° is equal to π radians:

What is stock dividend ?Similar to a cash dividend, however instead of cash, stocks are given out. A stock dividend will increase the number of shares outstanding while lowering the stock price.
In this issue, there are 460000 shares outstanding at a price of $30, which equals 13800000
Equity's total market value is $13800000.
Each shareholder will get a 20% increase in stock, and the number of existing shares will increase as a result of the 20% stock dividend.
Shares outstanding after dividend announcement total 460000 + 46000 ×20% =552000.
The number of outstanding common shares will rise to 552000 as a result of the issuance of 92000 more shares.
Common stock only contains the par value; for example, if the market price of a share is $30 and the par value is $1, the excess amount of $29×92000:2668000 is added to the capital surplus account. It will total 861000 + 2668000=3529000.
Due to the absence of any monetary transactions, the total owners' equity is unaltered.

You have 7/8 of a cup of tomato sauce. You must fill small containers with exactly 1/4 of a cup of tomato sauce How many containers can you fill completely?
Answers
Using division, If you have 7/8 of a cup of tomato sauce and you must fill small containers with exactly 1/4 of a cup of tomato sauce, then number of containers can fill completely is 3 containers
The total quantity of tomato sauce that you have = 7/8 of a cup
The quantity of tomato sauce with you must fill small containers = 1/4 of a cup
To find the number of containers that you can fill completely, you have to use division
Number of containers can fill completely = The total quantity of tomato sauce that you have / The quantity of tomato sauce with you must fill small containers
= 7/8 ÷ 1/4
= 7/8 × 1/4
= 7/2
= 3.5
≈ 3 containers
Hence, using division, if you have 7/8 of a cup of tomato sauce and you must fill small containers with exactly 1/4 of a cup of tomato sauce, then number of containers can fill completely is 3 containers

Answers
The B points are ( 8, -2 ) of Endpoint B when M is the midpoint of line AB.
What is midpoint of a segment?
The midway of a line segment in geometry is where it meets the other end. The centroid of the segment and the endpoints, it is equally spaced from both endpoints. It cuts the section in half.M is the midpoint of line AB.
Endpoint A is (4, 2).
Midpoint M is (6, 0)
Let mid points are ( x,y) and A points are ( x₂ , y₂ ) and B points are ( x₁ , y₁)
x = x₁ + x₂/2 , y = y₁ + y₂/2
6 = x₁ + 4/2 , 0 = y₁ + 2/2
12 = x₁ + 4 , 0 = y₁ + 2
x₁ = 12 - 4 , y₁ = -2
x₁ = 8 , y₁ = -2
So, the B points are ( 8, -2 )
