In physics class, Carrie learns that a force, F, is equal to the mass of an object, m, times its acceleration, a. She writes the equation F=ma.

Using this formula, what is the acceleration of an object with F=7.92 newtons and m=3.6 kilograms? Express your answer to the nearest tenth

Answers

Answer:

2 m/ s

a = F / m

a= 7.92 / 3.6

ie . 2.2 m/ s

Answer:

Step-by-step explanation:

1st step is by rearranging the formula

F=ma

M=f/a

A=f/m

2nd step is use the acceleration formula

A=f/m (acceleration=force divided by mass)

3rd step answer the question using the formula

A=?

F= 7.92N

M=3.6Kg --- 3600g (optional)

A=7.92/3600= 0.0022N/g or 7.92 / 3.6= 2.2N/Kg

4th step turning them to the nearest tenth

0.0022N/g= 0.0N/g or 2.2N/Kg= 2.2N/kg

DONE

TO SEE IF THE ANSWER IS CORRECT USE THE F=MA formula

compare and contrast between x-intercept and y-intercept

Answers

Answer:

"The x-intercept is the point at which the graph crosses the x-axis... ...The y-intercept is the point at which the graph crosses the y-axis." (Lumen)

The x-intercept is on the horizontal axis while the y-intercept is vertical axis. Aside from that they are practically the same and serve the same purpose while graphing, they just go in differing positions.

The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x-axis. ... The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero.

In a group of 150 people, 39 of them wear glasses. What is the probability of randomly selecting a person who does not wear glasses?

A. 111/150
B. 39/111
C. 111/189
D. 189/150
E. 39/150

Answers

Answer:

A. 111/150

Step-by-step explanation:

Because we know that 39 people out of the 150 in the group wear glasses, we need to subtract that from the total. This gives us 111 people that don't wear glasses.

Therefore, the probability of choosing someone not wearing glasses is 111/150.

Can someone help me with these questions.

Answers

Answer:

C ( x = 2 (multiplicity of 2), x = -2, x = -4)

A ( x = 5 (crosses), x = -3 (touches))

Step-by-step explanation:

Here are a couple of rules that helped me come to these answers.

1. When finding a zero, you flip the value inside of the parenthesis. For example (x + 2) would have the zero of x = -2.

2.The multiplicity of something is how many times the same zero is there. It is the exponent outside of the equation. For the first question, the (x - 2) has an exponent of 2, thus it has the multiplicity of 2.

3. The multiplicity determines whether the line just touches (or "bounces" off) the x axis or crosses the x axis. If the multiplicity is odd, it crosses the axis. If the multiplicity is even, it just touches the axis. A good way to remember this is with linear and quadratic equations. A linear is commonly know as only having an exponent of 1 (an odd) number and would cross the x axis. A quadratic equation has an exponent of two (an even number) so the line "bounces" on a graph.
