3/7 because if u do the cross cancel, 6 divided by 2 u get 3 so it’d be 3/7 x 1/1 equals to 3/7

Given the arithmetic sequence with the following two

kondor19780726 [428]

Answer:

aₙ = -15 + 10 * (n-1)

Step-by-step explanation:

aₙ = a₁ + (n-1)*d a₁: first term d: common difference

a₅ a₁ + 4d =25 .... (1)

a₁₁ a₁ + 10d = 85 ...(2)

(2) - (1) 6d = 60

d = 10

a₁ = -15

Formula: aₙ = -15 + 10 * (n-1)

The Hudson Bay tides vary between 3 feet and 9 feet. The tide is at its lowest point when time (t) is 0 and completes a full cyc

BaLLatris [955]

Answer:

$y(t)= 6-3cos(\dfrac{2\pi}{14}t )$

Step-by-step explanation:

The function that could model this periodic phenomenon will be of the form

$y(t) = y_0+Acos(wt)$

The tide varies between 3ft and 9ft, which means its amplitude $A$ is

$A =\dfrac{(9-3)ft}{2} \\\\\boxed{A = 3ft}$

and its midline $y_0$ is

$y_o=3+3 \\\\\boxed{y_o= 6ft}$ .

Furthermore, since at $t=0$ the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is $-cos(\omega t)$ .

The period of the full cycle is 14 hours, which means

$\omega t =2\pi$

$\omega (t+14)= 4\pi$

giving us

$\boxed{\omega = \dfrac{2\pi}{14}.}$

With all of the values of the variables in place, the function modeling the situation now becomes

$\boxed{y(t)= 6-3cos(\dfrac{2\pi}{14}t ).}$

What are three ways to get 256 using exponents

Nastasia [14]

recall from the previous posting, 2⁸ = 256, so that's one way to represent it.

now, another way hmmm

$\bf 2^8\implies 2^{2\cdot 4}\implies (2^2)^4\implies (4)^4\implies 4^4
\\\\\\
\stackrel{\textit{yet another way}}{2^8\implies 2^{4\cdot 2}}\implies (2^4)^2\implies (16)^2\implies 16^2$

yuson must complete 30 hours of community service. she does 2 hours each day. which linear equation represents the hours yuson h

algol [13]

Answer:

30-2x

Step-by-step explanation:

yuson has to finish am total of 30 hours in community service

she does 2 hours each day

in x days, hour of service done=2x

after x days hours of service left=30-2x

therefore the linear equation representing the hours yuson has left after x days is:

30-2x
