Answer:

C.) Juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast. What is the total amount of calories he consumed?

Step-by-step explanation:

A discrete graph is a series of scatter plot points. It means point on graph aren't continuous manner.

Option A) Kiley bought a platter for $19 and several matching bowl that were $8 each. If she bought x number of bowl her total cost would be

C(x)=19+8x . This is linear function and the graph of linear function is continuous.

This is not discrete graph.

Option B) Temperature at 9:00 AM was 83°F and heating up average rate of 6°F per hour.

Temperature after t hours would be

T(t)=83+6t . This is linear function and the graph of linear function is continuous.

This is not discrete graph.

Option C) Juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast.

Total calories = 78 + 110 . Total calories not depend on any variable.

This is discrete graph.

Option D) a bottle contained 2,000 mL of liquid and is being poured at an average rate of 300 mL per second

W(t)=2000-300t , This is linear function and the graph of linear function is continuous.

This is not discrete graph.

Complete the equation of the line whose yyy-intercept is (0,-1)(0,−1)left parenthesis, 0, comma, minus, 1, right parenthesis and

ioda

Answer:

$y=4x-1$

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

$m=4$

$b=-1$

Substitute

$y=4x-1$

Evaluate. 58−(14)2=58-142= ________

nasty-shy [4]

For this case we have the following expression:

$58- (14) ^ 2$

The first step is to solve the quadratic term.

We have then:

$58- (14) ^ 2 = 58-196$

Then, the second step is to subtract both resulting numbers:

$58- (14) ^ 2 = -138$

We observe that the result obtained is a negative number.

Answer:

The result of the expression is given by:

$58- (14) ^ 2 = -138$

KC has a piece of gum stuck to her bike tire, which applies a forward torque (i.e. a force to roll forwards) on the tire's movem

Kruka [31]

Answer:

t(d) = 0.01cos(5π(d-0.3)/3)

Step-by-step explanation:

Since we are given the location of a maximum, it is convenient to use a cosine function to model the torque. The horizontal offset of the function will be 0.3 m, and the horizontal scaling will be such that one period is 1.2 m. The amplitude is given as 0.01 Nm.

The general form is ...

torque = amplitude × cos(2π(d -horizontal offset)/(horizontal scale factor))

We note that 2π/1.2 = 5π/3. Filling in the given values, we have ...

t(d) = 0.01·cos(5(d -0.3)/3)
