Answer:

C. They both have the same slope.

Step-by-step explanation:

We have the function f(x) = 3x-3.

Substituting values of x in above f(x), we get the pair of points (0,-3) and (1,0).

Now, we will find the slope m of this function using,

m = \frac{y_{2} -y_{1} }{x_{2}- x_{1} }

i.e. m = \frac{0 - (-3)}{1-0}

i.e. m = 3.

Now, we are given that the function g(x) passes through the points (0,2) and (1,5).

We will find the slope of g(x) also by using the formula above,

i.e. m = \frac{5 - 2}{1-0}

i.e. m = 3.

Hence, we can see that both f(x) and g(x) have slope 3.

So, they both have same slope.

Let's find the slope of the line through (0,2) and (1,5)

m = (y2 - y1)/(x2 - x1)
m = (5-2)/(1-0)
m = 3/1
m = 3

So the slope of g(x) is 3. The slope of f(x) is also 3. The two functions have the same slope.

you are riding a bicycle which has tires with a 25-inch diameter at a steady 15-miles per hour, what is the angular velocity of
motikmotik

Answer:

The angular velocity is 6.72 π radians per second

Step-by-step explanation:

The formula of the angular velocity is ω = \frac{v}{r} , where v is the linear velocity and r is the radius of the circle

The unit of the angular velocity is radians per second

∵ The diameter of the tire is 25 inches

∵ The linear velocity is 15 miles per hour

- We must change the mile to inch and the hour to seconds

∵ 1 mile = 63360 inches

∵ 1 hour = 3600 second

∴ 15 miles/hour = 15 ×  \frac{63360}{3600}

∴ 15 miles/hour = 264 inches per second

Now let us find the angular velocity

∵ ω = \frac{v}{r}

∵ v = 264 in./sec.

∵ d = 25 in.

- The radius is one-half the diameter

∴ r = \frac{1}{2} × 25 = 12.5 in.

- Substitute the values of v and r in the formula above to find ω

∴ ω = \frac{264}{12.5}

∴ ω =  21.12 rad./sec.

- Divide it by π to give the answer in terms of π

∴ ω = 6.72 π radians per second

The angular velocity is 6.72 π radians per second

Answer:

80.95

Step-by-step explanation:

Percentage increase = \frac{New Value - Old Value}{Old Value} *100

=> (38-21)* 100/21 = 80.9523%

The answer round it to the nearest 100th = 80.95%

Step-by-step explanation:

1st digit is 1 number (1)

2nd digit is (3,4,5) so it's 3 numbers

third digit is (6,7,8,9) is it's 4 numbers

last 7 digits is 10 (0,1,2,3,4,5,6,7,8,9)

multiply

1*3*4*10=120

so answer is 120 phone numbers
