To prove :One plus cot square theta into tan theta by sec square theta = cot theta

pickupchik [31]

we are given

$\frac{(1+cot^2(\theta))*tan(\theta)}{sec^2(\theta)} =cot(\theta)$

We will simplify left side and make it equal to right side

Left side:

$\frac{(1+cot^2(\theta))*tan(\theta)}{sec^2(\theta)}$

we can use trigonometric identity

$1+cot^2(\theta)=csc^2(\theta)$

we can replace it

$\frac{(csc^2(\theta))*tan(\theta)}{sec^2(\theta)}$

we know that

csc=1/sin and sec=1/cos

so, we can replace it

and we get

$\frac{cos^2(\theta)tan(\theta)}{sin^2(\theta)}$

now, we know that

tan =sin/cos

$\frac{cos^2(\theta)*sin(\theta)}{sin^2(\theta)*cos(\theta)}$

we can simplify it

and we get

$\frac{cos(\theta)}{sin(\theta)}$

we can also write it as

$=cot(\theta)$

Right Side:

$cot(\theta)$

we can see that

left side = right side

so,

$\frac{(1+cot^2(\theta))*tan(\theta)}{sec^2(\theta)} =cot(\theta)$ ......Answer

Olivia deposited $2,136.70 into a saving account with an interest rate of 2.7% compounded quarterly. About how long will it take

mariarad [96]

Answer:

23.3 years

Step-by-step explanation:

4000 = 2136.7(1 + .027/4)^(4t)

4000 / 2136.7 = 1.00675^4t

ln (4000 / 2136.7) / ln 1.00675^4 = t

23.301690290541729158877031400229 = t

Please help me with math please, they are number lines

Ierofanga [76]

U have to rearrange to find x.
So first u look at the equation and u see u have to - 29 as u have to get x on its own.
This leaves u with:
6<3x
Now u have to divide by 3 to finally get x on its own, so this would leave u with the answer:
2<x

And the number line which represents this is B.
