1/4 of a mile times 9 equals 9/4 miles in total.
The horses time was 2.5 minutes.
Her average speed is distance/time.
9/4*1/2.5=9/10
Her average speed was 9/10 of a mile per minute.
<u>Answer:
</u>
The vertex of the function
is (h,k) = (3 , -1)
<u>Solution:
</u>
The vertex form of quadratic equation is generally given as,

Where h,k is the vertex of the parabola.
From question, given that
.
we have to find the vertex of the function.
Let us first convert the given quadratic equation to vertex form (eqn 1)

By adding “9” on both sides of equation, we get


By using the identity
,the right hand side of above equation becomes,


Now,the equation
is of the vertex form.
By comparing
with 
we get the values of (h,k)
a = 1; h = 3; k = -1
hence the vertex of the function
is (h,k) = (3 , -1)

Answer:
No
Step-by-step explanation:
Use the pythagorian theorm to find whether it's a right triangle or not.
So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared
5.2 squared= 2.4 squared+ 4m5 squared
27.04= 26.01
It's not equal so the triangle isn't a right triangle.
