Matthew is 26 years old. He buys 50/100/25 liability insurance, and collision and comprehensive insurance, each with $250 deduct
jonny [76]

Answer:

<em>$1,846.9</em>

Step-by-step explanation:

Liability Insurance 50/100/25

Where 50/100=$310; and 25=$175. The equation is ($310+$175=<em><u>$485</u></em>)

Collision & Comprehensive Premiums

Where Deductible=$250; Collision=$185; and Comprehensive=$102. The equation is ($250+$185+$102=<em><u>$537</u></em>)

He gets a 25-29 aged male rating factor of 1.55 for each of them. Liability's equation is $310*1.55=<u>$</u><em><u>480.5</u></em>; and for Collision and Comprehensive the equation is $(185+102)*102=<em><u>$344.4</u></em>

Added all up (<em>$485+$537+$480.5+$344.4=</em><em><u>$</u></em><em>1,846.9)</em>

Simplifying trigonometric expressions help?

7.

\dfrac{\sin\theta\cdot\cot\theta}{\tan\theta\cdot\cos\theta}=\dfrac{\sin\theta}{\cos\theta}\cdot\dfrac{1}{\tan\theta}\cdot\cot\theta=\tan\theta\cdot\dfrac{1}{\tan\theta}\cdot\cot\theta=\boxed{\cot\theta}

8.

\dfrac{\cot\theta}{\cos\theta}\cdot\dfrac{\sin\theta\cdot\cos^2\theta}{1-\cos^2\theta}=\dfrac{\cot\theta}{\cos\theta}\cdot\dfrac{\sin\theta\cdot\cos^2\theta}{\sin^2\theta}=\cot\theta\cdot\dfrac{\cos\theta}{\sin\theta}=\cot\theta\cdot\cot\theta=\\\\\\=\boxed{\cot^2\theta}

Answer:

12(x+ 30)

Step-by-step explanation:

360 is the down payment and 12x is the monthly payment

With regards to the function as monthly we realise there are 12 months in a year so it could equally mean (12 months x amount) or $12 dollars multiplied by x)

Factorising  We always put the highest common factor outside of the brackets when dealing with 2 numbers that can include variables such as x or 12x counting as one of the two.

12x+360

12(x+ 30)

Which is done as 12 x 30 = 360

We always try units first in numbers end in zero ie) 30 into 60 is x2 and 30 into 300 is 10 so our first highest common factor is 12 as its our largest number available from the smallest number given being 12.

So 12 is our highest common factor.

A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one
