Mathematics
1 answer:
Assoli18 [71]2 years ago
5 0

Answer:

Step-by-step explanation:

put x=r cos θ

y=r sin θ

r²cos²θ-r²sin²θ=3rsin θ

r²(cos²θ -sin²θ)=3r sin θ

r²cos 2θ=3rsinθ

r cos 2θ=3 sin θ

r=3sec 2θ sin θ

Between what two integers does 160 lie
Annette [7]
An integer is a whole number, not a fraction or decimal. Integers can be positive or negative. 180, 4, 17, -56 are all integers. 4.5, 38 1/2, 88.7 are not integers because they are not whole numbers.

ANSWER: 160 lies between 159 and 161.

Hope this helps! :)

Each of the variables t, w, x, y, and z represents a different positive real number. Given the equations below, which of the 4 v
alex41 [277]

Answer:

y has the greatest value.

Step-by-step explanation:

1.23w = t

Divide both sides by 1.23.

w=\frac{t}{1.23}

w=0.813t  --- (1)

1.01x = t

Divide both sides by 1.01.

x=\frac{t}{1.01}

x=0.99t --- (2)

0.99y = t

Divide both sides by 0.99.

y=\frac{t}{0.99}

y=1.01t --- (3)

From (1), (2) and (3), it is clear that y has the greatest value.

The ratio of the number of left-handed batters to the number of right handed batters is 5:8. There are 45 left-handed batters. f
Anuta_ua [19.1K]
Answer=15:39

Step1(find the number of right handed batters)

Left-handed batters=45

 5    45
__=___
8      x


Cross multiply
5x=360
divide both sides by 5
x=72
Right-handed batters=72

Step 2 (find the number of total batters)
total batters=45+72=117

Step3 (find the ratio of left handed batters to total batters)

Left-handed batters to total batters= 45/117
45/117 can be shortened to 15/39

Answer=15:39

A company makes a $5 profit on each non-faulty product it sells. Approximately 2% of the products manufactured are faulty.
galben [10]

Step-by-step answer:

The steps are much easier to follow when we know how many product it sells.  The number does not really matter, because we need the profit per item.

Say, the company made and sold 100 items of the product.

The revenue = 100*5 = $500.

On the average, 2 out of 100 are defective and need to be replaced at a cost of $100 each, so

replacement cost = 2* 100 = 200

So net profit for 100 items = $500 -$200 = $300

Net profit for each item = $300/100 = $3.00

Remark: since the product is replaced, no refund is necessary, so revenue stays at $300.
