Answer:
C 4x -2y = 1
Step-by-step explanation:
The y-intercept of the offered choices can be found by dividing the constant by the y-coefficient.
A: not in standard form (coefficients are not integers)
B: 2/-5 = -2/5 . . . not -1/2
C: 1/-2 = -1/2 . . . a good candidate
D: 1/-1 = -1 . . . not -1/2
Answer:
The answer to your question is:
a) sinФ = -4/√17
b) cosФ= 1/√17
c) tanФ = -4
Step-by-step explanation:
Just draw a right triangle where the opposite leg is -4/√17 the adjacent leg is 1/√17 and the hypotenuse is 1.
then sine Ф = opposite / hypotenuse = -4/√17 / 1 = -4/√17
cosine Ф = adjacent /hypotenuse = 1/√17 / 1 = 1/√17
tan Ф = opposite / adjacent = -4/√17 / 1/√17 = -4/1

Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
