Answer 1

Answer: Ouch.
Well, let's see.

First let's get ourselves oriented.
Where in the world are we ?:

-- The 'csc' (cosecant) of anything is 1/sine .

-- If the csc is negative, that tells us the sine of it is also negative ... -2/5 .

-- Since the sine is negative, that means the angle is in the
3rd or 4th quadrant ... between 180° and 360°.

-- But the question also says that the angle is between π and 3π/2 .
That's the 3rd quadrant ... between 180° and 270°.

I think that helps. That's the quadrant where the 'x's and the 'y's
are all negative. So we can immediately throw out the middle \
two choices. It has to be either first or the last choice .

The rest is kind of too hard to explain.
Please see the attached picture.

Solve this system of equations by using an algebraic method.Equation:
y = 3x + 5
3x - y = 5

Answers

Answer:

Step-by-step explanation:

Substitute our first equation into the second equation. We are given y, so this is ideal of substitution method.

y = 3x + 5
3x - y = 5

3x - (3x + 5) = 5
3x - 3x - 5 = 5
-5 = 5

There is no solution for the system because after solving, the sides of the equation are not equal. We can further check this by writing the second equation in a "y = mx + b form, or slope-intercept form. This well tell use about the graphs of the equations.

3x - y = 5
-y = -3x + 5

y = 3x -5

When comparing with the first equation, we can see that the slope is 3 for both lines, but the y-intercept is different. This means we have two parallel lines that cross the y-axis at (0, 5) and (0, -5). From this, one can conclude there is no solution because parallel lines with different y-intercepts will never cross.

A new car sells for $25,000. The value of the car decreases by 15% each year. What is the approximate value of the car 5 years after it is purchased?

Answers

The answer is $11,092.63.

This could be calculated using the proportion. If the value of the car decreases by 15% each year, that means that after each year the value of the car is 85% of the value from the first year.

After 1st year:
$25,000 : 100% = x1 : 85%
x1 = $25,000 · 85% ÷ 100%
x1 = $21,250

After 2nd year:
$21,250 : 100% = x2 : 85%
x2 = $21,250 · 85% ÷ 100%
x2 = $18,062.5

After 3rd year:
$18,062.5 : 100% = x3 : 85%
x3 = $18,062.5 · 85% ÷ 100%
x3 = $15,353.12

After 4th year:
$15,353.12 : 100% = x4 : 85%
x4 = $15,353.12 · 85% ÷ 100%
x4 = $13,050.15

After 5th year:
$13,050.15 : 100% = x5 : 85%
x5 = $13,050.15 · 85% ÷ 100%
x5 = $11,092.63

Therefore, the value of the car 5 years after it is purchased is $11,092.63.

Find the area of the triangle

Answers

Hello!

To find the area of a triangle, first multiply the base by the height. Afterwards, divide the product by 2.

Base: The bottom side of the triangle.
Height: The distance from the bottom to the top of the triangle.

Base = 13
Height = 18.2

13 × 18.2 = 236.6

Now we do the final step, which is to divide by 2.

236.6 ÷ 2 = 118.3

118.3 is your answer.

But why do we divide the product of the base and the height by 2? This is because a triangle is recognized as half of a rectangle/square.

:)

I think it should be 118.3 the equation is base times height divided by two equals the area

What formula tells the cost, in dollars, if chocolate chip cookies are $2.50/ dozen and lemon frosteds are $1.50/dozen? let c=number of dozens of chocolate chip cookies;L=number of dozens of lemon frosted; T= total charge

Answers

c= # of dozens chocolate chip cookies= $2.50/dozen

L= # of dozens of lemon frosted= $1.50/dozen

T= total charge

Multiply the number of dozens of chocolate chip cookies by the cost per dozen. Multiply the number of lemon frosted by the cost per dozen. Add those two together to equal the total cost.

T= ($2.50 * c) + ($1.50 * L)
T= $2.50c + $1.50L

ANSWER: T= $2.50c + $1.50L

Hope this helps! :)

Given: ABCD is a parallelogram.Prove: ∠A and ∠D are supplementary.

Parallelogram A B C D is shown.

By the definition of a parallelogram, AB∥DC. AD is a transversal between these sides, so ∠A and ∠D are
angles. Because AB and DC are
, the same-side interior angles must be
by the same-side interior angles theorem. Therefore, ∠A and ∠D are supplementary.
