The first term of an AP can be defined as T1 i.e. n=1. According to the given equation,. T1=a=2(1)+9=11.
Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A =
(14 × 4) = 28
Answer:
$425
Step-by-step explanation:
Let x represent the number of bracelets made and let y represent the number of necklace made.
Since the craftsman has 1000 beads to work with, hence:
10x + 20y ≤ 1000 (1)
Also, the craftsman has 1600 minutes, hence:
10x + 40y ≤ 1600 (2)
From ploting equations 1 and 2 on the geogebra online graphing, we can see that the solution to the problem is (40, 30).
Since the bracelet costs $5 and a necklace costs $7.50, hence the maximum revenue is:
Revenue = 5x + 7.5y = 5(40) + 7.5(30) = $425
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)
-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared
so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)
A = 3.14 x 36
A = 113.1
If the width is Wthen the length is 2W-5 W(2W-5)=422W2-5W = 422W2-5W-42 = 0 Factor by grouping or do the quadratic equation.Multiply the coefficient of the squared term.. 2..by the constant ..-42.. 2(-42)=-84Factors of -84 that add to the coefficient..-5.. ofthe W term are 7(-12)Replace the -5W with -12W + 7W 2W2-12W+7W-42 = 02W(W-6) + 7(W-6)=0(2W+7)(W-6)=0
Either: 2W+7 = 0 or W-6 = 0 2W = -7 W = 6 cm W = -7/2 cm
Since W will not be a negative, our width is 6cmThe length is 2W-5 = 2(6)-5=12-5 = 7 cm
