Sanic ran 420 meters in 21 seconds what was his speed?
Yes this is a real question please help
Answer:
the speed is 20 m/s
Step-by-step explanation:
The computation of the speed is as follows
As we know that
Speed = Distance ÷ time
where,
Distance is 420 meters
And, the time is 21 seconds
So, the speed is
= 420 ÷ 21
= 20 m/s
hence, the speed is 20 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered

Hello!
[tex]\large\boxed{k = 10^{o}}[/tex]
When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:
m∠YZX + m∠ZXY ≅ m∠MYZ
(4k + 5)° + (6k + 10)° = 115°
Combine like terms:
10k + 15 = 115°
Subtract 15 from both sides:
10k = 100°
Divide both sides by 10:
k = 10°
Answer:
k=10
Step-by-step explanation:
First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.
Second you would set the equations equal to 115
4k+5+6k+10=115
Then you would combine the like terms
10k+15=115
next you would subtract the 15 from both sides
10k=100
then you divide by 10
k=10

Let f(x) = 5x-7 and g(x) = 2x-3. Find f(x)+g(x)
Answer:
7x - 10
Step-by-step explanation:
f(x)= 5x - 7
g(x)= 2x - 3
f(x) + g(x)
= 5x - 7 + 2x - 3
= 7x - 10
The sum of f(x) and g(x) is 7x - 10.
To find the sum of f(x) and g(x), you simply need to add the two functions:
f(x) + g(x) = (5x - 7) + (2x - 3)
Now, combine like terms:
f(x) + g(x) = 5x + 2x - 7 - 3
f(x) + g(x) = 7x - 10
Therefore, the sum of f(x) and g(x) is 7x - 10.

Salim wants to purchase tickets from a vendor to watch a tennis match. The vendor charges a one-time service fee for processing the purchase of the tickets. The equation T = 15n +12 represents the total amount T, in dollars, Salim will pay for n tickets. What does 12 represent in the equation?
Given:
The equation [tex]T=15n+12[/tex] represents the total amount T, in dollars, Salim will pay for n tickets.
To find:
What does 12 represent in the equation?
Solution:
The vendor charges a one-time service fee for processing the purchase of the tickets.
We have, the equation
[tex]T=15n+12[/tex]
Here, 15 is the coefficient of n and 12 is constant.
If n is number of tickets then 15 must be the price of each ticket.
12 is free from variable and it is fixed. So, it represents one-time service fee for processing the purchase of the tickets.
Therefore, 12 represents that one-time service fee for processing the purchase of the tickets is $12.

On each of Maggie’s bird-watching trips, she has seen at least 36 birds. If she has taken 3 of these trips each year over the past 15 years, at least how many birds has Maggie seen?
Answer:
Maggie has seen at least 1620 birds.
Step-by-step explanation:
Ok since Maggie sees 36 birds each trip that means she sees 108 birds every year since she takes 3 trips each year. 36×3=108
If she has been doing this for 15 years she has seen at least 1620 birds because 108×15=1620

Which statement is true?
А. The function f(x) tan(x) is an odd function because $(-) = -f(x).
В.The function f(1) = tan(t) is an even function because its graph is symmetric about the origin.
C. The function f(t) tan(r) is an odd function because its graph is symmetric about the y-axis.
D.The function f(t) tan(x) is an even function because f(-1) =
Answer:
We conclude that the function f(x) tan(x) is an odd function because f(-x) = -f(x).
Hence, option (A) is true.
Step-by-step explanation:
We know that if function is even, then f(-x) = f(x)We know that if the function is odd, then f(-x) = -f(x)We also know that
tan x = sin x / cos xso
f(-x) = sin (-x) / cos (-x)
= -sin (x) / cos (x)
= -tan (x)
= -f(x)
Thus, tan (x) is an odd function.
Therefore, we conclude that the function f(x) tan(x) is an odd function because f(-x) = -f(x).
Hence, option (A) is true.

Line p has an equation of y=8/3x+2. Line q, which is parallel to p, includes the point (-2,-5). What is the equation of line q?
Answer:
y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{8}{3}[/tex] x + 2 ← is in slope- intercept form
with slope m = [tex]\frac{8}{3}[/tex]
Parallel lines have equal slopes , thus
y = [tex]\frac{8}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 2, - 5) into the partial equation
- 5 = - [tex]\frac{16}{3}[/tex] + c ⇒ c = - 5 + [tex]\frac{16}{3}[/tex] = [tex]\frac{1}{3}[/tex]
y = [tex]\frac{8}{3}[/tex] x + [tex]\frac{1}{3}[/tex] ← equation of parallel line
