NISA [10]

Answer:

Step-by-step explanation:

Remember, the formulas for the lateral surface area of a pyramid is 12pl and the total surface area is 12pl+B .

Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder.

So, the formula for the lateral surface area of a right cone is L.S.A=πrl , where l is the slant height of the cone.

Find the lateral surface area of a right cone if the radius is 4 cm and the slant height is 5 cm.

L.S.A=π(4)(5)=20π≈62.82 cm2

andrew is counting the total calories in his breakfast. he knows that a bowl of his favorite cereal with milk has 200 calories.

KatRina [158]

Answer: The graph of line y= 200+25x represents the given situation.

Step-by-step explanation:

Here, y represents the total calories he takes while x represents ounces of fruit smoothies with his cereal.

And, He knows that a bowl of his favorite cereal with milk has 200 calories.

Also, He also likes to drink a fruit smoothie with his cereal where Each ounce of the smoothie adds 25 calories.

Therefore, y = 200+ 25x is the total calories he takes after drinking the x ounces fruit smoothie with his cereal.

The x- intercept of the above line = (-8,0)

And, y-intercept = (0,200)

If x= 1 y=225

If x=-1 y= 175

Therefore, (1,225) and (-1,175) are the point of the above lines

Thus, with help of above information we can plot the graph of line y = 200+ 25x.

(03.01) Is the following relation a function? y equals the sine of 3 x

nikdorinn [45]

A relation is a function if it passes the vertical line test. That graph in a coordinate plane is just a sin wave that is spread out. If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time. That makes it a function. It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!

Is the equation x=-5-y and 2+y=-x+3 coincident, intersecting, or parallel

Paha777 [63]

Well first, you have to get both equations to the y= form
y=mx+b

X=-5-y add y to x

y+x=-5 then subtract x

y=-x-5 is your equation
_____________________

for the second one:

2+y=-x+3 subtract 2

y=-x+1 is your equation
__________________________
Take both equations and compare:

Both the slopes are the same of -x, so that means the will lines never touch (also because of different y intercept)

So, the answer is parallel.
