Answer:
Option (1)
Step-by-step explanation:
Two functions 'f' and 'g' have been graphed in the picture attached.
Both the functions will be equal at the points where the values of these functions are equal.
Those points are the point of intersection of both the functions on the given graph.
At x = -4,
f(-4) = g(-4) = 4
At x = 0,
f(0) = g(0) = 4
Therefore, Option (1) will be the answer.
Answer:
- sin C=h/a
- substitution property of equality
- commutative property of multiplication
Step-by-step explanation:
Because two points determine a line, you can draw altitude BD perpendicular to AC with height h. By the definition of a sine ratio, <u>sin(C) = h/a</u>, which can be rearranged into a·sin(C) = h. The area of △ABC is A=1/2bh. The <u>substitution property of equality</u> can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the <u>commutative property of multiplication</u>.
___
The mnemonic SOH CAH TOA reminds you that the sine ratio is ...
Sin = Opposite/Hypotenuse
Here, the side of the right triangle opposite angle C is designated "h", the height of ∆ABC. The hypotenuse of that right triangle is side "a". So ...
sin(C) = h/a
__
The substitution property of equality lets you replace any expression with its equal. Here, we have h=a·sin(C), so we can use a·sin(C) in place of h in the formula for triangle area:
1/2bh = 1/2ba·sin(C)
__
The commutative property of multiplication lets you rearrange the order of the factors in a product, so ...
ba = ab
and
A = 1/2ba·sin(C) = 1/2ab·sin(C)
I think it’s B because 3.14 times 12 is 37.68.
It’s 5×2 which is 10 hope this helps:)
