Answer:
0.965925826 = 0.97
Step-by-step explanation:
just put in the calculator >>> cos(15)
-3(y+2)^2 - 5 + 6y
= -3(y^2 + 4y + 4) - 5 + 6y
= -3y^2 - 12y - 12 - 5 + 6y
= -y^2 - 6y - 17
Answer
(-1) y^2 + (-6) y + (-17)
1. Gather your data
2. organize your data from least to greatest
3. find the median of the data set
4. find the first and third quartiles
5. draw a plot line
6. mark your first, second and third quartiles on the plot line you created
7. make a box by drawing a horizontal line connecting your quartiles
8. make your outliers
9. connect your outliers to the box with the horizontal line
and there you go
Answer:
Step-by-step explanation:
1) ΔCPD & ΔEPF
∠CPD = ∠EPF { Vertically opposite angles}
∠CDP = ∠PFE {CD║EF, FD is transversal, Alternate interior angles are equal}
ΔCPD ≈ΔEPF {AA criteria for similarity }
Cross multiply
EF * 15 = 27 * 7.5
EF = 27 * 0.5
EF = 13.5 cm
ii) EF // AB, so Triangles ACB & ECF are similar triangles
AC = 37.5 cm
She can make 2 necklaces with 4 inches remaining of string.
