The amount of money in the account after 18 years will be $449.5.
What are congruent triangles?If two triangles have the same size and shape they are called congruent triangles. If we flip, turn or rotate one of two congruent triangles they are still congruent. If the sides of two triangles are the same then the triangles must have the same angles and therefore must be congruent.Given is a parallelogram as shown in the image.
In order to prove ABCD as a parallelogram, we can prove ΔABE and ΔCDE congruent to each other by Angle - Angle - Side congruent property as -
∠BAE = ∠DCE {Alt. int. angles}
∠ABE = ∠CDE {Alt. int. angles}
AB = CD {Given}
Therefore, she can prove ABCD as a parallelogram by proving -
ΔABE ≅ ΔCDE using AAS criteria.

Length of rectangle parking lot = 94 m
Width of rectangle pool = 85 m
Step-by-step explanation:
Given:
Perimeter of rectangle = 300 m
Width of rectangle parking lot = 56 m
Find:
Length of rectangle parking lot
Area of rectangle pool = 8,245 m²
Length of rectangle pool = 97 m
Find:
Width of rectangle pool.
Computation:
1. Perimeter of rectangle = 2[l+b]
2[56 + l] = 300
56 + l = 150
Length of rectangle parking lot = 94 m
2. Area of rectangle = L x B
97 x Width of rectangle pool = 8,245
Width of rectangle pool = 85 m
Answer:
The length of the rectangle parking lot is 94 meters.
Rectangle pool width = 85 m

write a quadratic function in the given form whose graph satisfies the given condition.
has a vertex of (5, -2) & passes through the point (3, 6) in vertex form
pls help...important...dont steal
Answers
Answer:
f(x) = 2(x-5)²-2
Step-by-step explanation:
The equation of a parabola in vertex form is y=a(x-h)²+k where (h,k) is the vertex and "a" represents how stretched or compressed the parabola is and what direction it travels.
Given a vertex of (5,-2) the equation so far is y=a(x-5)²-2
Since we want the parabola to pass through the point (3,6) we must find a value of "a" that satisfies this:
y=a(x-5)²-2
6=a(3-5)²-2
6=a(-2)²-2
6=4a-2
8=4a
2=a
This means that the quadratic function is f(x) = 2(x-5)²-2

Slope:
m=(y2-y1)/(x2-x1)
m=(2-3)/(4-2)
m= (-1)/2
m= -1/2
The Slope of the given line is -1/2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We take two points from the graph as (2, 3) and (4, 2).
Now, the slope of line is
= (3-2)/ (4-2)
= -1 / 2
= -0.5
Using Slope intercept form
y= mx+ b
y= -0.5x+ b
and, b = 4
so, the Equation of line is y= -0.5x+ 4.
