To find perimeter you must add all the side lengths together:

P = AB + BC + AC

The side lengths AC and BC are easy to find. You must simply count how many units they span. Please refer to the image below to see how I did this.

To find the length of AB is a bit trickier. Since the trianlge shown is a right trianlge you may use pythagorean theorem

a^{2} +b^{2}=c^{2}

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 6

b = 7

^^^Plug these numbers into the theorem

6^{2} + 7^{2} = c^{2}

solve for c

36 + 49 = c^{2}

c^{2} = 85

c ≈ 9.219

c ≈ 9.2 units

Hope this helped! Let me know if you have any further questions!

A student has learned that test scores in math are determined by this quadratic function: s(t) = -(t-6)^2 + 99
ser-zykov [4K]

Answer:

a. 6,  b. 99, c. 63

Step-by-step explanation:

A)  The function s(t) is in the vertex form. The standard vertex form is a(x-h)+k where the vertex is (h,k). The vertex is the highest (or lowest in some cases) point of the graph, so if we use s(t) to get the vertex we get that h=6 and k=99. This means that for a student to get a perfect score they need to study 6 hours

B) We can just take the k value from the first question because that's the highest value for s(t), so the highest score will be 99

C) For this one just plug in 0 for time, so -(0-6)^2+99. This equals -(-6)^2+99, which equals 99-36 =63
