If you would like to complete the factorization, you can do this using the following step:
9g^2 + 30g + 25 = (3g + 5) * (3g + 5) = (3g + 5)^2
The correct result would be 5.
Answer:
sin A = opp / hyp = 0.82
Step-by-step explanation:
The sine function is defined as the ratio of "opposite side" to "hypotenuse."
In the given triangle, sin A = opp / hyp = 10.3 / 12.6 = 0.82 (to the nearest hundredth). That's all you have to do here.
The cosine function is the ratio of "adjacent side" to "hyp." In the given triangle, the side adjacent to angle A has length 7 .2. Thus,
cos A = adj / hyp = 7.2 / 12.6 = 0.57 (to the nearest hundredth).
Answer:
Graph 2 (I've seen this question somewhere)
Step-by-step explanation:
Of all the options you were given, Graph 2 makes the most sense. Otherwise, if you weren't given options, then I should let you know that an exponential graph would represent that function (something that starts low, and slowly goes up infinitely).
Answer:
768-452.16=315.84
Step-by-step explanation:
Answer:
Step-by-step explanation:
let width=x
length=x+7
x(x+7)=30
x²+7x-30=0
x²+10x-3x-30=0
x(x+10)-3(x+10)=0
(x+10)(x-3)=0
either x=-10 (rejected being negative)
or x=3
width=3 cm
length=3+7=10 cm
Perimeter=2(10+3)=2×13=26 cm
