NASA is painting the nose cone of a sounding rocket with a special sealant which reduces the air-drag on the rocket. If they need to do two coats of the sealant, how many square feet are they painting? Use π = 3.14.A. 56.5 ft²B. 27.3 ft²C. 35.3 ft²D. 28.3 ft²
In order to determine the number of required square feet to paint the nose cone, use the following formula for the surface area of a cone without the base:
[tex]S=\pi rl[/tex]where
r: radius of the base of the cone = 3 ft
l: slant height of the cone = 6 ft
replace the previous values of the parameters into the formula for S and simplify:
[tex]S=(3.14)(3ft)(6ft)=56.5ft^2[/tex]Hence, 56,5ft^2 are required
What is the equation for the line in slope-intercept form?
Answer:
y = -2x - 4
Step-by-step explanation:
Slope intercept form : y = mx + b
Where
m = slopeb = y intercept Finding Y - InterceptThe y intercept is the point where the line crosses the y axis.
Here, just by looking at the graph we can say that the y intercept is at (0,-4) because that is where the line passes the y intercept.
This means that b = - 4
Finding the slopeWe can find the slope using the following formula
Slope = (y2-y1)/(x2-x1)
Where, (x1,y1) and (x2,y2) are any given points on the line
The points used can vary however I have chosen (0,-4) and (-2,0)
Defining our variables we get (x1,y1) = (0,-4) and (x2,y2) = (-2,0)
So we have x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0
We now plug this in to the formula
Slope = (y2-y1)/(x2-x1)
==> plug in x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0
Slope = (0-(-4))/(-2-0)
==> remove parenthesis
Slope = (0+4)/(-2-0)
==> simplify addition and subtraction
Slope = 4/-2
==> simplify fraction
Slope = -2
So the slope or "m" is -2
Plugging the y intercept and slope into y intercept formAgain we have y = mx + b
m = slope so m = -2 and b = y intercept so b = -4
Plugging this in, we acquire y = -2x - 4
The president of a bank projects that the earnings from one investment will be $47,000 this year. He also plans to buy some municipal bonds that yield 25% annual interest. How much money should he invest in the bonds so that the total earnings from the two investments will be at least $80,000?
The investment amount that the bank president should make in the bonds so that the total earnings from the two investments will be at least $80,000 is $132,000.
How is the amount determined?The earnings from the second investment are the difference between the total expected earnings and the first investment's earnings.
Using the above difference obtained by subtraction, the investment amount is computed by dividing the difference by the annual interest rate.
The total earnings from the two investments ≥ $80,000
The profits from one investment = $47,000
The earnings from the second investment should be ≥ $33,000 ($80,000 - $47,000)
The annual interest rate on municipal bonds = 25%
The investment amount = $132,000 ($33,000 ÷ 25%)
Thus, if $132,000 were invested in municipal bonds at 25% interest, its annual earnings would be $33,000.

What is an absolute value function?In an absolute value function, an algebraic expression is contained within an absolute value symbol.
The given absolute value function is; y = -3·|x + 2| + 8
The slope of the rays are found as follows;
The general form of the absolute value function is; f(x) = a·|x - h| + k
The vertex of the function is the point (h, k)
The slope of the function is a
Comparing the specified function, y = -3·|x + 2| + 8, to the general function, we get;
The vertex of the function is (h, k) = (-2, 8)
The slope of the rays of the function are; a = 3
Slope of the ray 1 = (8 - (-19))/(-2 - (-11)) = 3
Slope of ray 1 is therefore; 3
Slope of ray 2 = (8 - (-19))/(-2 - 7) = -3
The slope of the ray 2 is therefore; -3

what would (9, 10) be after a rotation 270 degrees counterclockwise around the origin?
The new coordinates of the point (9, 10) after a rotation of 270 degrees counter-clockwise around the origin are (10, -9).
The coordinates of the point are (9, 10). We perform a transformation on the point. The type of transformation performed is rotation. The rotation is done at an angle of 270 degrees in a counter-clockwise direction around the origin. First of all, we need to convert the angle of rotation from degrees to radians. The angle θ is 270*(π/180) = 3π/2. Let the original coordinates be denoted by (a, b) and the coordinates after rotation be (x, y). We can write the following equations using the theory of rotation.
x = a×cos(θ) - b×sin(θ) = 9×cos(3π/2) - 10×sin(3π/2) = 0 - 10(-1) = 10
