i need help asap! math problem
Answer:
4
Step-by-step explanation:
cos(-π) = -1 [in radians]
3-(-1) = 4
There are many ways to answer this but, I'll try to explain it.
You can see that you are computing a limit when some n approaches negative PI. You get to substitute negative PI instead of n and compute cos(-pi) which is -1.
Then compute f(x) - (-1) = 3 - (-1) = 4 which is a result.
The way you can imagine cos(-pi) or cos(-90deg) is by dragging point in a unit circle beneath x-axis and to the bottom y-axis (-90 angle), the y coordinate tells you the cosine value at (-90) and because you have dragged the point on the unit down to y-axis the value is -1.
Hope this helps.

You would usually divide to see,
but also multiplying the number you can fit in 5/8 and the number you multiply it by.
triangles and rectangle
Step-by-step explanation:
Area of triangle (A1)
= 1/2 * b *h
= 1/2 * 1 * 1
= 1/2 ft
Area of rectangle (A2)
= L * b
= 3 *1
= 3 ft
Total area
= A1 + A2
= 1/2 + 3
= (1 + 6 ) / 2
= 7/2 ft²
= 3.5 ft²

Calculate the muscular work completed by four men. Four men carry 20 boxes each up a ramp as shown. Each box weighs 5 pounds. Remember that muscular work is calculated by multiplying the weight by the vertical distance. In the calculation, disregard the weight of the men and consider only the muscular work done carrying the boxes.
A. 600 ft-lbs
B. 1200 ft-lbs
C. 2400 ft-lbs
D. 3600 ft-lbs
Answer:
2400 foot pounds
Step-by-step explanation:
The amount of work done by the four men is 1200 ft-lbs. so option B is correct.
How to calculate work done?The muscular work done by each man is equal to the weight of the boxes carried multiplied by the vertical distance moved.
The weight of each box is 5 pounds, and each man carries 20 boxes, so the total weight carried by each man is:
20 boxes x 5 pounds/box = 100 pounds
The vertical distance moved is the height of the ramp, which is 30 feet.
Therefore, the muscular work done by each man is:
Muscular work = weight x vertical distance
Muscular work = 100 pounds * 30 feet
Muscular work = 3000 ft-lbs
Since there are four men carrying boxes, the total muscular work done is:
Total muscular work = 4 * 3000 ft-lbs = 12000 ft-lbs
Therefore, the answer is B. 1200 ft-lbs.

The diameter of a circle has endpoints (2,-6) and (-4,-16).
Enter an equation for the circle in standard form.
Answer:
[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]
Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d = [tex]\sqrt{(2 + 4)^{2} + (-6 + 16)^{2} }[/tex]
= [tex]\sqrt{6^{2} + 10^{2} }[/tex]
= [tex]\sqrt{36 + 100}[/tex]
= [tex]\sqrt{136}[/tex]
r = [tex]\sqrt{136}[/tex]/2
[tex]r^{2}[/tex] = 136/4 = 34
Equation of circle with center at (-1, -11) and radius = [tex]\sqrt{34}[/tex] is
[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]

Answer:
3x - y = -3
Step-by-step explanation:
divide everything by 4, the greatest common factor. That's all you need to do.
Answer: y=3x+3
Step-by-step explanation:
12x -4y= -12
subtract 12x from both sides
-4y= -12x-12
Divide everything by -4 to make y positive and alone

The ratio of the measures of the sides of a triangle is 8: 15: 17, and its perimeter is 480 in.. Find the measure of the shortest side of the triangle.
Answer:
96
Step-by-step explanation:
The ratio of the measure of sides of a triangle are 8:15:17
The perimeter is 480
8x + 15x + 17x= 480
40x= 480
x = 480/40
x = 12
Therefore the measure of the shortest side of the triangle can be calculated as follows

in 2001 John makes an investment investment and $50,000 decreases in value of the rate of 2.5% per year write an exponential function to find the value of the investment in 2010
Answer:
$39811.77
Step-by-step explanation:
If we put y as the unit of year, the function will be 50000x0.975^y (100%-2.5% is 97.5%). And so from 2001 to 2010, nine years has passed, so the equation will be 50000x0.975^9 And if you calculate and round the answer to the nearest hundredth (cent), you will find $39811.77.

A salesperson's commission rate is 5%. What is the commission from the sale of $36,000 worth of furnaces? Use pencil and paper. Suppose sales would double. What would be true about the commission? Explain without using any calculations.
Answer:
a. $1,800
b. Commission would double as well.
Step-by-step explanation:
Commission paid on $36,000 worth of furnaces with a rate of 5% is:
= Amount of sales * commission rate
= 36,000 * 5%
= $1,800
If the sales were to double, the commission would be based on double the amount so it would double as well.
= 36,000 * 2
= $72,000
Commission = 72,000 * 5%
= $3,600
Commission therefore doubled.
Answer:
1,800
