Which statement regarding the function y=cos(x) is true?
MAVERICK [17]

B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph.  [false]
C. cos(x) = -cos(x)   [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin.   [false]</span>

Land in downtown Columbia is valued at $10 a square foot. What is the value of a triangular lot with sides of lengths 119, 147,
stiks02 [169]

Answer:

$87,461

Step-by-step explanation:

Given that the dimensions or sides of lengths of the triangle are 119, 147, and 190 ft

where S is the semi perimeter of the triangle, that is, s = (a + b + c)/2.

S = (119 + 147 + 190) / 2 = 456/ 2 = 228

Using Heron's formula which gives the area in terms of the three sides of the triangle

= √s(s – a)(s – b)(s – c)

Therefore we have = √228 (228 - 119)(228 - 147)(228 - 190)

=> √228 (109)(81)(38)

= √228(335502)

=√76494456

= 8746.1109071 * $10

= 87461.109071

≈$87,461

Hence, the value of a triangular lot with sides of lengths 119, 147, and 190 ft is $87,461.

Stephan curry of the golden state warriors made 29 baskets some were 2 points some were 3 points. If the total points he scores
seraphim [82]
<h2>Answer: He makes 261 baskets to earn 45 points.</h2>

Step-by-step explanation:

Since we have given that

Number of points = 2 + 3 = 5

Number of baskets = 29

if he makes 45 points,

We need to find the number of baskets.

According to question, we get that

\dfrac{5}{29}=\dfrac{45}{x}\\\\5x=45\times 29\\\\x=\dfrac{45\times 29}{5}\\\\x=261

Hence, he makes 261 baskets to earn 45 points.
