A parallelogram has vertices (5,0), (3, -3), (-4, -3) and (-2, 0) The
diagonals of the parallelogram intersect at their midpoints. A. What are the coordinates of the
intersection of their diagonals? Justify the answer algebraically.
Answer:
(0.5 , -1.5)
Step-by-step explanation:
intersection of their diagonals (E): right at the mid-point of segment AC or BD
A (5 , 0) and C (-4 , -3): E (x , y)
x = (5 + -4 ) / 2 = 0.5
y = (0 + -3 ) / 2 = - 1.5
E ( 0.5 , - 1.5)
check with BD: x = (3 + -2) / 2 = 0.5 y = (-3 + 0) / 2 = - 1.5

Step-by-step explanation:
The amount after 10 years will be $260.
What is compound interest?The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
Given amount invested = $220
rate = 1.7% compounded annually
time = 10 years
the amount is given by
A = p[tex](1 + \frac{r}{n} )^{nt}[/tex]
r = 1.7% = 0.017
n = 1 for compounded annually
t = 10 years
p = $220
A = 220(1 + 0.017)¹⁰
A = $260.39
A = $260
Hence the amount is $260.

58°
A, B, C and D are points on the circumference of the circle, centre O.
DOB is a straight line and angle DAC = 58°.
Find angle CDB.
Answer:
Angle CDB = 32
Step-by-step explanation:
Here, we want to find the measure of CDB
Mathematically;
angle DCB = 90
This is because angle at the center is twice the angle at the circumference
Also;
angle CAD = angle CBD = 58
This is because they are angles in the same segment
Furthermore;
CDB + 90 + 58 = 180
This is because sum of angles in a triangle is 180
CDB = 180-90-58
CDB = 32

Given:
The table of values is:
x y
-4 3
0 8
4 13
8 18
To find:
The slope of the line that described by the data in the table.
Solution:
Consider any two points from the given table.
Let the two points are (0,8) and (4,13). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{13-8}{4-0}[/tex]
[tex]m=\dfrac{5}{4}[/tex]
[tex]m=1.25[/tex]
Therefore, the slope of the line described by the data in the table is 1.25.
Does someone know the answer to this?
Answer:
both sides are congruent meaning it is a 45/45 triangle. that makes y=45. you can then use sin(45)=x/12 which when solved is 8.49 approximately
A triangular road sign has a height of 3 feet and a base of 2.5 feet. How much larger in area is this sign than one with a height of 2.5 feet and a base of 3 feet?
Answer:
Not larger or smaller; the areas are the same
Step-by-step explanation:
Recall that the formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
In the first case, h = 3 ft and b = 2.5 ft. This results in an area of 3.75 ft^2.
In the second case, h = 2.5 ft and b = 3 ft. The area is the same: 3.75 ft^2.
This is because A = (1/2)(b)(h) has the same value regardless of the order in which b and h are used as multipliers.
There is no difference in the areas of the two signs. The areas are the same.
