Answer:
A = 83.6 yd² ⇒ answer (d)
Step-by-step explanation:
∵ AB = 15 , AC = 15 and m∠A = 48°
∵ Area of the Δ by using sin Rule
∴ A = 1/2 × S1 × S2 × sin including angle between two sides
∴ A = 1/2 × 15 × 15 × sin48 = 83.6 yd² ⇒ answer (d)
Answer:
A, C, D
Step-by-step explanation:
One way to answer this question is to use synthetic division to find the remainder from division of the polynomial by (x-3). If the polynomial is written in Horner form, evaluating the polynomial for x=3 is substantially similar.
A(x) = ((x -2)x -4)x +3
A(3) = ((3 -2)3 -4)3 +3 = -3 +3 = 0 . . . . . has a factor of (x -3)
__
B(x) = ((x +3)x -2)x -6
B(3) = ((3 +3)3 -2)3 -6 = (16)3 -6 = 42 . . . (x -3) is not a factor
__
C(x) = (x -2)x^3 -27
C(3) = (3 -2)3^3 -27 = 0 . . . . . . . . . . . . . has a factor of (x -3)
__
D(x) = (x^3 -20)x -21
D(3) = (3^3 -20)3 -21 = (7)3 -21 = 0 . . . . has a factor of (x -3)
___
The polynomials of choice are A(x), C(x), and D(x).
Which inequality represents this situation ?
1.59×n < 20
How many charms can Marta purchase ?
20 : 1.59 = 12 (+$0.92)
Answer:
x = -1/3
Step-by-step explanation:
Move 5 to the other side of the equation
3x = 4-5
3x = -1
x = -1/3
