Answer:
(c) 40.5 square units
Step-by-step explanation:
Assuming the kite is oriented so its diagonals are parallel to the sides of the square, each diagonal is 9 units long. The area of the kite is given by an appropriate formula.
<h3>What is a kite?</h3>
A kite is a parallelogram with two pairs of adjacent congruent sides. Its diagonals meet at right angles. One diagonal bisects the other.
<h3>Kite area</h3>
The formula for the area of a kite is ...
A = 1/2(d1)(d2) . . . . . where d1 and d2 are the lengths of the diagonals
In this problem, the inscribed kite has congruent diagonals, both of length 9 units.
The area of the kite is ...
A = 1/2(9)(9) = 81/2 = 40.5 . . . . square units
Answer:
y = -2x - 5
Step-by-step explanation:
The slope of the given line is found by solving 2y + 4x = 8 for y:
2y = -4x + 8, or y = -2x + 4. The slope is -2.
We need to find the equation of a line parallel to this one and with y-intercept -5:
y = mx + b becomes, after suitable substitutions, y = -2x - 5
Answer:
see explanation
Step-by-step explanation:
Given a quadratic function in standard form y = ax² + bx + c ( a ≠ 0)
• If a > 0 the the graph has a minimum value ∪
• If a < 0 then the graph has a maximum value ∩
Thus y = - 3x² + 1 ← has a maximum value and
y = x² ← has a minimum value
Answer:
<h2>3</h2>
Step-by-step explanation:
<h3>Step 1: Identify two points on the line</h3>
1,2 & 2,5
<h3>Step 2: Select x1, y1 & x2, y2</h3>
x1 = 2, y1 = 5 x2 = 1, y2 = 2
<h3>Step 3: Use the Slope Formula</h3>
change y/ change x
<u><em>IMPORTANT: it is change in y over change in x, not the other way around. It will be wrong if done the other way, though that would seem to be more logical, since x is the first variable in the pair.</em></u>
Y 5 -2 = 3
X 2 - 1 = 1
3/1 = 3
