If the triangle ABC is enlarged using the point P as a center, then the point of the dilated triangle will be A'(-3, 2), B'(1, 2), and C'(-1, -2).
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
The coordinate of point P will be (5, 4).
Let shift the origin at P, then the coordinate of ABC will be
A(-4, -1), B(-2, -1), and C(-3, -3)
If the scale factor is 2. Then the coordinate of the triangle A'B'C' will be
A'(-8, -2), B'(-4, -2), and C'(-6, -6)
Then shift the origin at (0, 0), then the coordinate of A'B'C' will be
A'(-3, 2), B'(1, 2), and C'(-1, -2)
The graph is shown below.

The area of room is 812 square feet, cost of carpet to cover the room is $6739.6 and the remaining square feet of carpet are covered by furniture is 203 square feet.
What is the area of trapezoid?The area of the trapezoid is the space occupied by it on the two dimensional plane. The area of this figure is half of the product of height and sum of sides.
[tex]A=\dfrac{(a+b)h}{2}[/tex]
Here, (a and b) are the base sides of the trapezoid and (h) is the height.
A room is shaped like a trapezoid which has the height of 28 feet and the length of sides as 23 ft and 35 ft. Thus, the area of it is,
[tex]A=\dfrac{(a+b)h}{2}\\A=\dfrac{(23+35)28}{2}\\A=812\rm\; ft^2[/tex]
Carpet costs $8.30 per square foot. Thus, the cost of carpet with area 812 ft² is,
C=812×$8.30
C=$6739.6
Furniture covers 25% of the floor. Thus, the remaining square feet of carpet are covered by furniture is,
[tex]A=\dfrac{25}{100}\times812\\A=203\rm\; ft^2[/tex]
Thus, the area of room is 812 square feet, cost of carpet to cover the room is $6739.6 and the remaining square feet of carpet are covered by furniture is 203 square feet.

What is a function?A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.
Let f(x) = abˣ + c

Then similarly, by satisfying the above table in f(x) will be
[tex]\rm f(x) = - \dfrac{33}{5} \left ( \dfrac{1}{11} \right )^x - \dfrac{17 }{5} \\\\f'(x ) > 0[/tex]
Then we can say f(x) is an increasing function.

Jada fills the bathtub before taking a bath and then allows the water to drain when she is done. The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes.
On a graph, the graph increases, remains constant, and then decreases.
Is the number of gallons of water in the bathtub a function of time?
Yes because each t value is paired with exactly one number of gallons.
Yes because the number of gallons is bounded between y = 0 and y = 36.
No because each number of gallons is paired with more than one t value.
No because from t = 5 to t = 20 the number of gallons of water is constant.

Answer:
x = -2, -5
Step-by-step explanation:
x^2 + 7x + 10 = 0
The factors of 10 are as follows:
1, 10
2, 5
We can combine 2 and 5 to make 7
(x +2) (x + 5) = 0
One of these brackets must equal 0 to make the answer 0, as you are multiplying them together
If x + 2 = 0, x = -2
If x + 5 = 0, x = -5
Therefore, x = -2, -5

ax² + bx + c = 0 where a ≠ 0
The sign of the discrimant (b² - 4ac) determines the number of real-number solutions :
If the discrimant is positive, the equation has two real-number solutions.If the discrimant is equal to zero, the equation has one real-number solution.If the discriminant is negative, the equation has no real-number solution.The solutions of the equation, also called roots, can be obtained with the QUADRATIC FORMULA :
[tex]x = \frac{ - b - \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]
---------------------------------------------------------------
▪️ x² + 7x + 10 = 0
(1) Substitute the letters in the general quadratic equation with their values in the given expression:
a = 1b = 7 c = 10(2) Determine the sign of the discriminant:

Step-by-step explanation:
2 things to remember :
1. the sum of all angles in a triangle is always 180°.
2. the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
triangle 1 :
angle B = 180 - 62.2 - 43.8 = 74°.
a/sin(62.2) = 15.8/sin(74)
a = 15.8 × sin(62.2)/sin(74) = 14.53961961... in
c/sin(43.8) = 15.8/sin(74)
c = 15.8 × sin(43.8)/sin(74) = 11.37657122... in
triangle 2 :
14.9/sin(49) = 11.6/sin(A)
sin(A) = 11.6 × sin(49)/14.9 = 0.587559136...
angle A = 35.98398776...° ≈ 36°
angle C = 180 - 49 - 35.98398776... = 95.01601224...° ≈
≈ 95°
c/sin(95) = 14.9/sin(49)
c = 14.9 × sin(95)/sin(49) = 19.66708505...
newly weds triangle :
let's call the 2 sides a and b (25 m and 30 m).
the angle between them is 60°.
here we should use the extended Pythagoras for general triangles :
c² = a² + b² - 2×a×b×cos(C)
with c being the side opposite to the angle C.
so, we have in our case
c² = 25² + 30² - 2×25×30×cos(60) = 625 + 900 - 750 =
= 775
c = sqrt(775) = sqrt(25×31) = 5×sqrt(31) = 27.83882181... m
the area of the triangle we get via Heron's formula :
s = (a+b+c)/2 = (25+30+c)/2 = 41.41941091...
area = sqrt(s(s-a)(s-b)(s-c)) = sqrt(s(s-25)(s-30)(s-c)) =
