Answer:
4 inches
Step-by-step explanation:
The radius is the line from the center of the circle to the edge. We can assume the black line on the orange is the radius.
We want to find the diameter. The diameter is twice the radius, or
d=2r
We know the radius is 2, so we can substitute that in for r
d=2*2
Multiply
d=4
So, the diameter is 4 inches
Answer:
Vertex: (- 2, -1)
axis of symmetry: x= - 2
Step-by-step explanation:
f(x)=x^2+4x+3
f(x)=(x^2+4x+4)+3-4.......complete the square
f(x)=(x+2)^2-1...................write in vertex form
20 it’s 5 divided by 1/4 which is 20
We know that
in the triangle TQS
<span>applying the Pythagorean theorem
QS</span>²=TS²+TQ²---------> TQ²=QS²-TS²--------> TQ²=18²-9x²-----> equation 1
in the triangle TRS
TS²=TR²+RS²--------------> TR²=TS²-RS²-------> TR²=9x²-144----> equation 2
in the triangle QTR
TQ²=TR²+36-----------> equation 3
<span>I substitute 1 and 2 in 3
</span>18²-9x²=9x²-144+36--------> 18x²-432=0------> x²=24-------> x=√24
x=2√6
TS=3*x------> 3*2√6-----> 6√6
TS=6√6 units
the answer is
TS=6√6 units
<span>6 is the square root of 6 units</span>
Answer is: Solve for h by cross multiplying.
h = 7
So A. 7 is the correct answer.
