In the coordinate plane, the point A, 4− 2 is translated to the point A′, 1− 5. Under the same translation, the points B, 7− 4 and C, 2− 5 are translated to B′ and C′, respectively. What are the coordinates of B′ and C′?
Answer:
The coordinates of B' and C' are [tex]B'(x,y) = (4, -7)[/tex] and [tex]C'(x,y) = (-1, -8)[/tex], respectively.
Step-by-step explanation:
From the Linear Algebra, we define the translation of a given point as:
[tex]O'(x,y) = O(x,y) + T(x,y)[/tex] (1)
Where:
[tex]O(x,y)[/tex] - Original point, dimensionless.
[tex]T(x,y)[/tex] - Translation vector, dimensionless.
[tex]O'(x,y)[/tex] - Translated point, dimensionless.
If we know that [tex]A'(x,y) = (1, -5)[/tex] and [tex]A(x,y) = (4,-2)[/tex], then the translation vector is:
[tex]T(x,y) = A'(x,y)-A(x,y)[/tex] (2)
[tex]T(x,y) = (1,-5)-(4,-2)[/tex]
[tex]T(x,y) = (-3,-3)[/tex]
If we know that [tex]B(x,y) = (7,-4)[/tex], [tex]C(x,y) = (2,-5)[/tex] and [tex]T(x,y) = (-3,-3)[/tex], then the translated points are, respectively:
[tex]B'(x,y) = B(x,y)+T(x,y)[/tex] (3)
[tex]B'(x,y) = (7,-4) +(-3,-3)[/tex]
[tex]B'(x,y) = (4, -7)[/tex]
[tex]C'(x,y) = C(x,y) +T(x,y)[/tex]
[tex]C'(x,y) = (2,-5) + (-3,-3)[/tex]
[tex]C'(x,y) = (-1, -8)[/tex]
The coordinates of B' and C' are [tex]B'(x,y) = (4, -7)[/tex] and [tex]C'(x,y) = (-1, -8)[/tex], respectively.

If anyone can please answer and explain will mark the brainliest answer
Answer:
a) [tex]y=\frac{1}{3} \sqrt{x+4}[/tex]

Step-by-step explanation:
Part a is the green curve
Part b is the purple curve
Part c is the red curve
The black curve is the equation of the graph [tex]y=\sqrt{x}[/tex]

Sally paid $2.40 for 4 ounces of cinnamon. If there are 16 ounces in 1 pound, how much does cinnamon cost per pound
Answer:
$12.80 per pound
Step-by-step explanation:
Since there are 16 ounces in 1 pound, we multiply $0.80 by 16 ounces to find how much cinnamon costs per pound. The answer is $12.80.
Hope this helped, Have a Wonderful Day!!
Answer:
$9.60 per pound
Step-by-step explanation:
- 4 ounces = 2.40 each
- 2.40 x 4 (4 because 4x4 is 16 and there are 16 ounces in a pound)
= $9.60
pls i need a lot of help bc is a lot of work idk how to do
-2w(w+8)
Answer:
-2w² + -16w
Step-by-step explanation:
-2w(w+8)
Multiply each term by -2w
(-2w * w) + (-2w * 8)
-2w² + -16w
Answer:
-2[tex]w^2[/tex] - 16w
Step-by-step explanation:
multiply w and 8 by -2w.
when you multiply w by 2w, you get -2[tex]w^2[/tex] and 8 times -2w = -16w
-2[tex]w^2[/tex] - 16w

A polynominal function that describes an enclosure is v(x)=1500x_x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Answer:
The answer is below
Step-by-step explanation:
A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Solution:
The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:
V'(x) = 0
V(x) = x(1500 - x) = length * breadth.
This means the enclosure has a length of x and a width of 1500 - x
Given that:
v(x)=1500x-x². Hence:
V'(x) = 1500 -2x
V'(x) = 0
1500 -2x = 0
2x = 1500
x = 1500 / 2
x = 750 feet
The maximum area = 1500(750) - 750² = 562500
The maximum area = 562500 feet²
Answer:
562500 feet²

Answer : 2.142L
Step-by-step explanation:
51/100 × 4.2
=51/100 × 42/10
= 2142/1000
= 2.142L
Answer:
2.142 LStep-by-step explanation:
Total Volume = 4.2L = 4200 ml
Amount Drunk = 51%
How much did Johan drink = 51% of 4200 ml
[tex] \frac{51}{100} \times 4200 \\ = \frac{51 \times 42}{1} \\ = 2142[/tex]
2142 ml = 2.142 L

A local charity receives 13of a fundraiser during a craft fair and a bake sale. The total amount given to charity was $137.45. How much did the bake sale raise?
Complete question :
A local Charity receives 1/3 of funds raised during a craft fair and bake sale. The total amount given to the charity was $137.45. How much did the bake sale raise
Answer:
$412.35
Step-by-step explanation:
Given that:
Fraction Given to charity from bake sale = 1/3 of amount raised
Amount given to charity = $137.45
Let amount raised from bake sale = x
Hence,
1/3 of x = 137.45
x / 3 = 137.45
x = 137.45 * 3
x = $412.35
Amount raised from bake sale = $412.35

A bungee jumper dives from a bridge over a river. The function ℎ(푡) = −16푡 % +5푡 +250 gives the approximate height h in feet of the jumper until he hits the water for the first time. The variable t is measured in seconds.
Answer and Explanation:
Given the function:
ℎ(t)= −16t+5t+250
Where the variable t is measured in seconds. We can plug in t=20 seconds in the function to measure the height in feet of the bungee jumper after 20 seconds.
h(t)= -16×20+5×20+250
h(t)= -320+100+250
h(t)=350-320
h(t)= 30feet
height in feet of the bungee jumper after 20 seconds = 30 feet

Step-by-step explanation:
In ΔFGH, \text{m}\angle F = (6x-14)^{\circ}m∠F=(6x−14) ∘ , \text{m}\angle G = (4x-8)^{\circ}m∠G=(4x−8) ∘ , and \text{m}\angle H = (x+15)^{\circ}m∠H=(x+15) ∘ . Find \text{m}\angle F.M∠F.
Answer:
[tex]\angle F =\bold{88^\circ}[/tex]
Step-by-step explanation:
Given a [tex]\triangle FGH[/tex] with the following angles:
[tex]\text{m}\angle F = (6x-14)^{\circ}[/tex]
[tex]\text{m}\angle G = (4x-8)^{\circ}[/tex]
[tex]\text{m}\angle H = (x+15)^{\circ}[/tex]
To find:
[tex]\text{m}\angle F[/tex] = ?
Solution:
Here, we can simply use the angle sum property of a triangle to find the value of [tex]\text{m}\angle F[/tex].
As per the angle sum property of a triangle, the sum of all the interior angles a triangle is equal to [tex]180^\circ[/tex].
[tex]\angle F + \angle G + \angle H = 180^\circ[/tex]
Putting all the given values in the above equation, we get:
[tex](6x-14)^{\circ} + (4x-8)^{\circ} + (x+15)^{\circ} = 180^\circ\\\Rightarrow 11x-7=180^\circ\\\Rightarrow 11x=180+7\\\Rightarrow 11x=187\\\Rightarrow x = \bold{17}[/tex]
Putting the value of [tex]x[/tex] in [tex]\angle F[/tex]
[tex]\text{m}\angle F = (6x-14)^\circ\\\Rightarrow \text{m}\angle F = (6\times 17-14)^\circ\\\Rightarrow \text{m}\angle F = \bold{88^\circ}[/tex]
