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.

If j(x) = x4 - 81, and k(x) = x + 3 then j(x) k(x) =
Bad White [126]
Hi there!
The question here is asking us to multiply two functions together - j(x) and k(x). First, we need to determine the expressions for j(x) and k(x). Since this is given, we can move straight onto multiplying the two functions together, which will give us our answer.
j(x) × k(x)
Substitute expressions - 
(x⁴ - 81)(x + 3)
Simplify - 
(x⁴ - 81)(x + 3)
x⁵ + 3x⁴ - 81x - 243
Therefore, the answer is x⁵ + 3x⁴ - 81x - 243. Hope this helped!

Find all solutions of each equation on the interval 0 ≤ x<2π.
Aleksandr [31]

Answer:

x = 0 \: or \:x =   \pi

Step-by-step explanation:

The given equation is

\tan^{2} (x) \sec^{2} (x)  + \sec^{2} (x)  - \tan^{2} (x) =  2

Subtract 2 from both sides and factor by grouping to get:

\sec^{2} (x)(\tan^{2} (x) + 2)  -1( \tan^{2} (x)  +  2)

(\tan^{2} (x) + 2) (\sec^{2} (x) - 1) = 0

By the zero product principle:

(\tan^{2} (x) + 2) = 0 \: or \:  (\sec^{2} (x) - 1) = 0

(\tan^{2} (x)  =  - 2 \: or \:  \sec^{2} (x)  =  1

When

\sec^{2} (x)  =  1 \implies\cos^{2} (x)  =  1

\implies \:  \cos(x)  =  \pm1

This implies

x = 0 \: or \:x =   \pi

When

{ \tan }^{2} (x) =  - 2

We have

\tan(x)  =  \pm \sqrt{ - 2}

hence x is not defined for all real numbers
