Answer:

v = 20.7 mph

Step-by-step explanation:

Given that,

Distance, d = 400 m

Time, t = 44.62 s =

We need to find the speed of the sprinter. The speed of an object is defined as total distance covered divided by time taken. It can be given by :

v=\dfrac{d}{t}\\\\=\dfrac{0.248\ mile}{0.012\ s}\ (As\ 1\ m=0.000621371\ mile)\\\\=20.7\ mph

Hence, the speed of the sprinter is equal to 20.7 mph.

Ten times the square of a non-zero number is equal to forty times the number
S_A_V [24]
To convey as an algebraic expression simply break down the statements and use any variable to represent the number in the sentence.

10 • x^2 = 40x
10x^2 = 40x
10x^2 - 40x = 0
10(x^2 - 4x) = 0
X(x - 4) = 0

X = 0

X - 4 = 0
X = 4.

Here are two possibilities of what the number can be, but because it is a nonzero number, I believe it would be 4.

What is the sum of the geometric sequence 4, 16, 64, ƒ if there are 8 terms?
pogonyaev
In a Geometric Sequence,<span> each term is found by </span>multiplying<span> the previous term by a </span>constant<span>. For this case, the constant is 4. To find the sum of the geometric sequence with 8 terms, we use the formula as follows:

</span>∑(ar^k) = a ( 1-r^n) / (1-r)
<span>
where a is the first term, r is the constant, n is the number of terms

 </span>∑(ar^k) = 4 ( 1-4^8) / (1-4)
∑(ar^k) = 87380
