Answer:
Step-by-step explanation:
Standard form:
Vertex form:
(h, k) is the vertex
x is the coordinate of the vertex
To find x use the formula:
a=1
b=-2
c=-6
Substitute:
Substitute x in equation:
h=1
k=-7
Substitute h, and k into the vertex formula:
(0,3) because if you go up six on the Y axis you get three. If you go two over on the X axis you reach zero.
Answer:
using Pythagoras rule, 16^2 -7^2 =a^2
so 256-49 = 297.
√207 =14.38 to the nearest tenth of an inch is 14inch.which is your answer
Answer:
i think it's 10 lmk if it's wrong lol
Step-by-step explanation:
<u>Step 1: List out all of the formulas for the trigonometric functions
</u>
<em>sin(x) </em>= opposite/hypotenuse
<em>cos(x)</em> = adjacent/hypotenuse
<em>tan(x) </em>= opposite/adjacent
<u>Step 2: Find the value of RS
</u>
cos(31) = RS/24.8 NOT 24.8/RS
sin(31) = QS/24.8 NOT RS/24.8
sin(31) = QS/24.8 NOT 24.8/RS
cos(31) = RS/24.8 WHICH IS SAME AS RS/24.8
Answer: The correct length would be given from Option D, cos(31) = RS/24.8
