I THINK
A. 6 ft²
B. draw a diagonal; each triangle would be half the area: 3 ft²
Step-by-step explanation:
Part A:
The area is the product of the length of one of the parallel sides and its distance from the other:
A = bh = (8 ft)(3/4 ft) = 6 ft²
__
Part B:
A parallelogram can be divided into two congruent triangles by either of its diagonals. Since the triangles are congruent, each will have 1/2 the area of the parallelogram. In this case, each triangle's area would be ...
(1/2)6 ft² = 3 ft²
Answer:
The distance is
Step-by-step explanation:
First we need to find the slope of the line and the the its equation, for the slope we use the formula:
Using the line equation we have that:
(1)
Converting the line equation (1) into its general form
Finally we use the distance between a line and point formula given by
where A, B and C are the coefficients of the line and x and y are the coordinates of the point P
Answer:
1. b=-7
2. c= -10
Step-by-step explanation:
The standard form for the quadratic function is
ax^2 +bx+c
so we need to rewrite the function to be in this form
2x^2 -10 = 7x
Subtract 7x from each side
2x^2 -7x-10 = 7x-7x
2x^2 -7x-10 = 0
a =2, b= -7 c=-10
