Okay. To find the speed in meters, do 75 * 1,000. because 1,000 meters = 1 kilometer. 75 * 1,000 is 75,000. The speed is 75,000 meters an hour. But, it asks for meters per second and there are 3,600 seconds in one hour. To find this, we have to do division. 75,000/3,600 is 20.8 when rounded to the nearest tenth. The car goes about 20.8 meters per second.
Rise over run or how much it goes up or down over how much it goes left or right
Answer:
Step-by-step explanation:
So let's find the equation of the line for f(x). We know the y-intercept, also known as b in the equation of the line for f(x), is 3. (b = y-intercept = 3)
y = mx + <u>b</u>
y = mx + <u>3</u>
Now, to find the slope you must use the formula of...
(y₂ - y₁) / (x₂ - x₁)
We have two points of the line already shown. We will now use the formula to find out the slope.
(3 - 1) / (0 - 1) = 2 / -1 = -2, the slope is -2. (m = slope = -2)
y = <u>m</u>x + 3
y = <u>-2</u>x + 3
Now check the following statements and see which ones are true.
A is <em>not </em>a true statement.
B is <em>not </em>a true statement because a slope of -6 is steeper than -2. The negative slope only changes the direction of the line.
C is <em>not </em>a true statement because the slope of f(x) is not undefined.
D <u>is</u> a true statement because the line of f(x) is less steep than the slope of g(x).
KEEP IN MIND THE SLOPE IS M IN THE EQUATION OF A LINE.
Answer:
1.
Step-by-step explanation:
I am assuming you want to simplify this.
cos^2 x + sin^2 x = 1 and
csc^2 x = 1 + cot^2 x so csc^2x - cot^2 x = 1
So the answer is 1/1 = 1.
