The point (3, -4) lies in the quadrant 4. 

The length of the vector will be = \sqrt{(3)^{2} +(4)^{2} } =5

cos theta can be found by dividing the horizontal component of the vector (which is 3) with the length of the vector.

So,

cos(theta)= \frac{3}{5}

How would u do this problem ?? #9
Ad libitum [116K]
Since the scale factor is 4:3 then every dimension of triangle WXY is (3/4) of every dimension of triangle CDE.
The perimeter of triangle CDE = 13 + 22 + 29 = 64.
So, the perimeter of triangle WXY = (3/4) * 64 = 48

An asset has a cost of $50,000, with a residual value of $10,000. It has a life of 5 years and was purchased on January 1. Under

<h3>What is double-declining-balance?</h3>

An enhanced technique for recording loss over the lifetime of a product by adjusting the item's starting sales price by a discount factor.

An asset has a cost of $50,000, with a residual value of $10,000.

It has a life of 5 years and was purchased on January 1.

Then the asset’s fourth full year of depreciation expense will be

Annual depreciation = (cost – salvage value)/ useful life

Annual depreciation = (50000 – 10000) / 5 = $8,000

Year 1 Depreciation (for 10 months, from March to December) = $8,000 × 10/12 = $6,666.67.

More about the double-declining-balance link is given below.

Think of 5 positive integers that have a mode of 3, a median of 5, a mean of 7 and a range of 12.
kiruha [24]

For the mode to be 6, there has to be at least two 6s.

For the median to be 6, with two 6s, there must be at least one number above 6.

For the mean to be 6, the sum is 30, so the three remaining numbers must total 18.

Simplify: -4(x - 6) + 3(a - 7)
Korolek [52]

We have -4(x - 6) + 3(a - 7) = -4x + 24 + 3a - 21 = -4a + 3a + 3

so the answer is B

ok done. Thank to me :>
