If B=16°45’ and c=13 then find a (picture provided)

SIZIF [17.4K]

Answer:

A. 12.4

Step-by-step explanation:

To find a, we'll use the Law of Sines that says:

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

And we'll isolate a to get:

$a = \frac{sin(A) * c}{sin(C)}$

We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:

A = 180 - 90 - 16.75 = 73.25

(converted 16°45' to 16.75)

Then we will plug-in the information we already have

$c = \frac{sin(73.25) * 13}{sin(90)} = 12.45$

So, let's round it to 12.4 to match the answer A.

Write a quadratic function with a graph that meets the following conditions: x-intercepts at (2, 0) and (6, 0) with a minimum at

Darya [45]

The minimum is the vertex
y=a(x-h)^2+k
(h,k) is vertex
given
(4,-8)
y=a(x-4)^2-8
find a
given
(2,0) and (6,0)
find a

0=a(2-4)^2-8
0=a(2)^2-8
0=4a-8
8=4a
divide 4
2=a

other one
0=a(6-4)^2-8
0=a(2)^2-8
0=4a-8
8=4a
divide 4
2=a

the function is
y=2(x-4)²-8 or expanded
y=2x^2-16x+24
