Let h represent the height of the plant after a certain amount of weeks
let w represent the number of weeks
h= 4 + 2w

explanation: 4 never changes but the variable which is w will affect the growth- per week, so we use w. If its 3 weeks then you do 4+2(3) and you get 10cm.

What is the value of theta for the acute angle in a right triangle?
balu736 [363]

we are given

sin(\theta)=cos(73)

we have to find theta

so, firstly we can write sin in terms of cos

sin(\theta)=cos(90-\theta)

now, we can set it equal

cos(90-\theta)=cos(73)

Since, both sides are cos

so, we can set angles equal

90-\theta=73

now, we can solve for theta

we get

\theta=17..............Answer

Find the sum of the first 20 terms of the arithmetic sequence 4, 10, 16, 22....
hammer [34]

n = 20

d = 6

a = 4

L = a + (n - 1)*d

L = 4 + (20 - 1)*6

L = 4 + 19*6

L = 118

Sum = (a + L)*n/2

Sum = (4 + 118) * 20/2

Sum = 122 * 10

Sum = 1220

Use FOIL.

(x-6)(4x+3)\\\\x*4x = 4x^2\\\\x * 3 = 3x\\\\-6 * 4x= -24x\\\\-6 * 3 = -18\\\\\\4x^2+3x-24x-18\\\\\boxed{4x^2-21x-18}

Hope this helps.
