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.
Answers
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

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.
Answers
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

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?
Answers
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.

The linear inequality (B) y>4x-5 represents the given solution set graph.
What is linear equality?A linear inequality in mathematics is an inequality involving a linear function. One of the symbols for inequality is found in linear inequality. It displays non-equal data in graph style. The boundary line that separates the coordinate plane into two halves by a linear inequality represents the solutions to the inequality in one half. For > and, the border line is solid, and for and, it is dashed. Typically, the half-plane that resolves the inequality is shaded.So, the linear inequality that represents the graph:
Graph the inequation as follows:
(A) y≥4x+5 (Refer to attached Graph 1)(B) y>4x-5 (Refer to attached graph 2)(C) y>-4x-5 (Refer to attached graph 3)Now, we can easily notice that graph 2 which is of equation (B) y>4x-5 matches the given graph.
Therefore, the linear inequality (B) y>4x-5 represents the given solution set graph.

David invested $220 in an account paying an interest rate of 1.7%
compounded continuously. Assuming no deposits or withdrawals are
made, how much money, to the nearest ten dollars, would be in the
account after 10 years?
Answers
Answer:
260 dollars
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.

(-7+1)/(5-1)=-6/4= -3/2 is the slope
answer is C
Answer:
C
Step-by-step explanation:
The formula for slope is rise/run
Rise is the difference between the y coordinates
Run is the difference between the x coordinates
To find the rise and run:
ex.
(a, b), (c, d)
rise:
d-b
run:
c-a
Slope:
d-b/c-a
In this situation:
rise:
-7-(-1)
run:
5-1
Slope:
-7-(-1)/5-1
= -6/4
=-3/2
