Identify the vertex of the graph. Tell whether it is a minimum or a maximum.

Mathematics
1 answer:
Sedbober [7]3 years ago
6 0

Answer:

Vertex = (-1, 2)  

Maximum

Step-by-step explanation:  

The middle point of the graph is at x coordinate -1 and the point is at the top while the graph slopes down so it is a maximum point and not a minimum point.

Given: NM ∥ XZ Prove: △XYZ ~ △NYM Triangles X Y Z and N Y M are shown. Triangle X Y Z is smaller and sits inside of triangle N Y
elena-s [515]

Answer:

Parallel

corresponding angles theorem

NYM

AA

Step-by-step explanation:  I DID IT ON EDGE! : )

We know that side NM is  _________________

✔ parallel

to side XZ. If we consider side NY the transversal for these parallel lines, we create angle pairs. Using the  _____________

✔ corresponding angles theorem

, we can state that ∠YXZ is congruent to ∠YNM. We know that angle XYZ is congruent to angle  _____________

✔ NYM

by the reflexive property. Therefore, triangle XYZ is similar to triangle NYM by the  _____________

✔ AA

 similarity theorem.

Parents wish to have $80,000 available for a child's education. If the child is now 5 years old, how much money must be set asid
Ludmilka [50]

Answer: $27,602.60

Step-by-step explanation:

if the kid is 5 years old, there are 13 years left until he is 18.

Now, suppose that the parents set aside an amount A of money in the account.

As the interest is compounded semiannually is compounded two times per year.

The equation that models this situation is:

M(n) = A*(1 + p/(c*100%))^(c*n)

where:

n is our variable, in this case, years.

p is the percentage, in this case, 6%

n is the number of compounds in one unit of the variable, in this case, we have 2.

A is the initial amount, this is the thing we want to find.

Then our equation will be:

M(n) = A*(1 + 6%/(2*%100))^(2*n)

       = A*(1 + 0.03)^(2*n) = A*(1.03)^(2n)

And we want that this is equal to $80,000 when n = 13 (remember that when n = 13, the child will be 18 years old)

M(13) = A*(1.03)^(2*18) = $80,000

           A = $80,000/((1.03)^(2*18)) = $27,602.60

Then they should deposit $27,602.60 now to meet their financial goal when the child is 18.

A triangular pyramid had a base with an area of 11.3 square meters, and lateral faces with bases of 5.1 meters and heights of 9
worty [1.4K]
+Well you need to multiply 11.3 times 4.5 per each triangle
Also you need to find the base which is a square
So 5.1 times 5.1 which is technically 5.1 squared. You add from there

EQUATION: 4(11.3 x 4.5) + 5.1 squared 
You should get 229.41
