kolezko [41]

Answer:

D. R(x)=850x+9600

Step-by-step explanation:

Use the given information as points on a line, and find the slope.

The two given points are (10, 18,100) and (20, 26,600).

slope = (difference in y)/(difference in x)

slope = (26,600 - 18,100)/(20 - 10)

slope = 8,500/10

slope = 850

Only choice D. has a slope of 850.

Answer: D. R(x)=850x+9600

sammy [17]

Answer:

$75^{\circ}$

Step-by-step explanation:

Given: $\csc (x) = 1.0353$

To find: angle to the nearest degree

Solution:

A triangle is a polygon that has three sides, three angles ,and three vertices.

Trigonometry explains the relationship between the sides and angles of the triangle.

The angle can be expressed in two forms: degrees or radians.

$\csc (x) = 1.0353\\x=74.995\approx 75^{\circ}$

Let A and B be sets with cardinal numbers , n(A) = a and n(B) = b respectively . Decide whether the statement is true or false.

olya-2409 [2.1K]

Answer:

True

Step-by-step explanation:

$A\cup B=A\cup(A-B)\\\\A\ and\ A-B\ are\ disjoint\ that\ means\ there\ is\ no\ common\ element\ in\ these\ two.\\\\n(A\cup B)=n(B\cup(A-B))\\\\n(A\cup B)=n(B)+n(A-B)\ \ \ \ \ \ \ as\ for\ disjoint\ set\ P,Q\ n(P\cup Q)=n(P)+n(Q)\\\\(n(P-Q)=n(P)-n(P\cap Q))\\\\n(AUB)=n(B)+n(A-B)\\\\n(AUB)=n(B)+n(A)-n(A\cap B)\\\\n(AUB)=n(A)+n(B)-n(A\cap B)\\\\Hence\ given\ statement\ is\ true$
