Answer: Answer:

An orthocenter is the intersection of three:

Altitudes in a triangle.

Step-by-step explanation:Altitude--

An altitude is a line segment that originates from a vertex and is perpendicular to the line segment opposite to that vertex.

Orthocenter--

An orthocenter of a triangle is a point where the three altitudes of a triangle meet or intersect.

In a right angled triangle the orthocenter is the vertex of the triangle where the right angle is formed.

Answer: Altitudes meet in an intersection. hope this helps

the line a bus arrives at the bus stop every 25 minutes and line b bus arrives every 15 minutes. both are atvthe bus stop now. in how many minutes will both be at the bus stop again

Answer: Both will be stop at the bus stop again after 75 minutes.

Step-by-step explanation:

Since we have given that

Line A bus arrives at the bus stop = every 25 minutes

Line B bus arrives at the bus stop = every 15 minutes

We need to find the number of minutes that both will be at the bus stop again.

For this we will find the L.C.M. of 25 and 15.

Since L.C.M. of 25 and 15 = 75

So, Both will be stop at the bus stop again after 75 minutes.

That means find the least common multplule of 15 and 25

factor each

15=3*5

25=5*5

lcm=3*5*5=75

factor each

15=3*5

25=5*5

Elevate the expression 3x-9 when x=5 show work

3×5=15-9=6 hope this helps

3x-9

Now, substitute for x=5

It would be: 3(5)-9 = 15-9 = 6

So, your answer is 6

Now, substitute for x=5

It would be: 3(5)-9 = 15-9 = 6

So, your answer is 6

Answer: The second derivative of the function is

Step-by-step explanation:

Since we have given that

We need to find the second derivative of the function.

So, the first derivative would be

Now, second derivative would be

Hence, the second derivative of the function is

The ratio of squirrels to chipmunks in the yard was 2:7. How many squirrels were in the yard if there were 49 chipmunks? Explain please.

Let the number of squirells be 2x and number of chipmunks be 7x ,

Given that number of chipmunks is 49, so

= > 7x = 49

= > x = 49 / 7

= > x = 7

So the number of squirells will be 2x = 2( 7 ) = 14

Given that number of chipmunks is 49, so

= > 7x = 49

= > x = 49 / 7

= > x = 7

So the number of squirells will be 2x = 2( 7 ) = 14
