The size of a TV is usually given by the length of the screen diagonal. If the screen dimensions of a TV are 16 inches by 12 inches, what size is this TV?
A)28 inch
B)20 inch
C)16 inch
D)12 inch
Answer:
A
Step-by-step explanation:
You have to do step by step
Applying the Pythagorean Theorem, the size of the TV that is 16 inches by 12 inches is: B)20 inch
Recall:
Diagonal of a rectangle can be found using the Pythagorean Theorem given as: [tex]d = \sqrt{l^2 + w^2}[/tex]Where, d = diagonal, l and w are the dimensions of the shape.Given:
l = 16 inches
w = 12 inches
Therefore,[tex]d = \sqrt{16^2 + 12^}\\[/tex]
[tex]d = \sqrt{400} \\\\\mathbf{d = 20 inches}[/tex]
Therefore, applying the Pythagorean Theorem, the size of the TV that is 16 inches by 12 inches is: B)20 inch

What does 2 (p -q) +5 (p+q) equal when p = 7 and q = -2? Answer:
Answer:
43
Step-by-step explanation:

= 2(7 + 2) + 5(7 - 2)
= 2(9) + 5(5)
= 18 + 25

Which table of values represents a line with a slope of 4/3
Answer:
c
Step-by-step explanation:
have a good day :D
to find the slope you take two points and add the y values and divide it by the x values
so you take the points (0,-2) and (3,2)
the y values are -2and2
2+2=4
the x values are 0 and 3
0+3=0
4/3=4/3 so that table does represent an equation with a slope of 4/3
