<span>1 sq yd = 36^2 sq in = 1296 sq in
so 170 sq in = 170/1296 sq yd
1 yd = 3 ft
1 ft = 12 in
170 sq in [ft/12 in] [ft/12 in] [yd/3 ft][yd/3 ft</span>
Answer:
168 meters squared
Step-by-step explanation:
The area of the triangle is A= 1/2 b*h. Here this area is 21 meters squared. The sides of the triangle have been multiplied by 4. This means, if the base was b, it is now 4b. This also means, if the height was h, it is now 4h. So the area is A= 1/2 4b*4h = 1/2 (16bh) = 8bh.
So the area of the larger triangle will be 8 times bigger.
21*8 = 168
Answer:
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product
Step-by-step explanation:
<span>389/x=47
To solve this, you must isolate x on one side.
First multiply both sides by x.
x(389/x) = x(47)
389 = 47x
Now divide both sides by 47 to find x.
389/47 = x
X is 389/47.</span>
Answer:
(i) [1,2]
(ii) [1,1,1]
(iii)
(iv)
(b)
Step-by-step explanation:
First. Let's find the displacement for every given time:
t=1s
t=2s
t=1.1s
t=1.01s
t=1.001s
Now, the average velocity can be found as:
Where:
Hence:
(i) [1,2]
(ii) [1,1,1]
(iii)
(iv)
(b) In order to estimate the instantaneous velocity of the particle for t=1, we need to find its derivative:
