The distance an object travels is determined by how fast it goes and for how long it moves.If an object speed remains constant,t

he formula is d=r•t, where d is the distance,r is the speed and t is the time. If you drive at 50 miles per hour for 5 hours,how far will you have traveled?
A.200 miles
B.10miles
C.250miles
D.300miles

Answer:

250 miles

Step-by-step explanation:

Your formula is d=r(t)

d=distance r=speed t=time

In this equation it is asking you how far will you travel if your speed is 50 miles per hour, and the time is 5 hours.

So, using the equation above insert the known numbers and it should look like this: d=50(5) ( distance is unknown / speed is 50 / time is 5 )

Now you can find the distance. All you do is multiply 50 times 5 which equals 250.

So the correct answer is C. 250 miles

Use the equation and type the ordered-pairs. y = log 3 x {(1/3, a0), (1, a1), (3, a2), (9, a3), (27, a4), (81, a5)

vagabundo [1.1K]

Answer:

Considering the given equation $y = log_{3}x\\$

And the ordered pairs in the format $(x, y)$

I don't know if it is log of base 3 or 10, but I will assume it is 3.

For $(\frac{1}{3}, a_{0} )$

$x=\frac{1}{3}$

$y=a_{0}$

$y = log_{3}x\\y = log_{3}(\frac{1}{3} )\\y=-\log _3\left(3\right)\\y=-1$

So the ordered pair will be $(\frac{1}{3}, -1 )$

For $(1, a_{1} )$

$x=1$

$y=a_{1}$

$y = log_{3}x\\y = log_{3}1\\y = log_{3}(1)\\Note: \log _a(1)=0\\y = 0$

So the ordered pair will be $(1, 0 )$

For $(3, a_{2} )$

$x=3$

$y=a_{2}$

$y = log_{3}x\\y = log_{3}3\\y = 1$

So the ordered pair will be $(3, 1 )$

For $(9, a_{3} )$

$x=9$

$y=a_{3}$

$y = log_{3}x\\y = log_{3}9\\y=2\log _3\left(3\right)\\y=2$

So the ordered pair will be $(9, 2 )$

For $(27, a_{4} )$

$x=27$

$y=a_{4}$

$y = log_{3}x\\y = log_{3}27\\y=3\log _3\left(3\right)\\y=3$

So the ordered pair will be $(27, 3 )$

For $(81, a_{5} )$

$x=81$

$y=a_{5}$

$y = log_{3}x\\y = log_{3}81\\y=4\log _3\left(3\right)\\y=4$

So the ordered pair will be $(81, 4 )$

The sum of an arithmeit cprogression consisting of 20 positive integer terms with positive common difference is equal to 2020. (

Rufina [12.5K]

Answer:

a) possible progressions are 5

b) the smallest and largest possible values of the first term are 16 and 82

Step-by-step explanation:

<u>Sum of terms:</u>

Sₙ = n/2(a₁ + aₙ) = n/2(2a₁ + (n-1)d)
S₂₀ = 20/2(2a₁ + 19d) = 10(2a₁ + 19d)
2020 = 10(2a₁ + 19d)
202 = 2a₁ + 19d

<u>In order a₁ to be an integer, d must be even number, so d = 2k</u>

202 = 2a₁ + 38k
101 = a₁ + 19k

<u>Possible values of k= 1,2,3,4,5</u>

k = 1 ⇒ a₁ = 101 - 19 = 82
k = 2 ⇒ a₁ = 101 - 38 = 63
k = 3 ⇒ a₁ = 101 - 57 = 44
k = 4 ⇒ a₁ = 101 - 76 = 25
k = 5 ⇒ a₁ = 101 - 95 = 16

<u>As per above, </u>

a) possible progressions are 5
b) the smallest and largest possible values of the first term are 16 and 82
