Answer:
Sin of x does not change
Step-by-step explanation:
Whenever a triangle is dilated, the angle remains the same as well as the ratio for sides of triangle. For smshapes with dimensions, when shapes are dilated the dimensions has increment with common factor.
From trigonometry,
Sin(x)=opposite/hypotenose
Where x=4/5
Sin(4/5)= opposite/hypotenose
But we were given the scale factor of 2 which means the dilation is to two times big.
Then we have
Sin(x)=(2×opposite)/(2×hypotenose)
Then,if we divide by 2 the numerator and denominator we still have
Sin(x)=opposite/hypotenose
Which means the two in numerator and denominator is cancelled out.
Then we still have the same sin of x. as sin(4/5)
Hence,Sin of x does not change
I would say he can because 1+1 = 2
Answer:
$4.1
Step-by-step explanation:
To find the Unit Rate, you have to find how much it cost of 1 lb. So, you have to divide 16 and 3.99
16/3.99
= 4.01002506
≈ $4.1
Perhaps you mean to find the volume under
? It seems like you have to rely on calculus otherwise (in the case that you indeed mean
).
Assuming this, note that
describes the top half of a sphere with radius 8, which means the volume below this surface over the disk
is simply half the volume of the sphere. Thus the volume is
Absolute value is just how many integers rhat number is away from 0. i say this because it’s not too hard of a thing to learn and it’s very important in the higher grades.
3 is 2 6/7
5 is a greater than symbol >
7 is 1/3 and negative 1/3 so -1/3
8 is 14 and -14
9 is 21 and -21
11 is | -75 |
i’m not sure about 13 but i believe it could be | -8 |
i hope this helped
