Answer:
about 14 hours
Step-by-step explanation:
1 hour = 60 mins
845 divided by 60 mins
equals to 14.83 repeated
it would take 14 hours to drive 845 miles
=(4/7)^3
=(4/7)*(4/7)*(4/7)
=4*4*4 / 7*7*7
=4^3 / 7^3
=64/343
Answer is D.
F(3)=-18
You just replace x for three for your equation and then use Ofer of operations to solve it.
So f(3)= 21+ 2(3)-5(3)^2
The exponent goes first: f(3)= 21+ 2(3)-5(9)
Next is multiplication: f(3)= 21+ 6-45
Now add: f(3)= 27-45
Finally subtract: f(3)= -18
Hope this helps!
Answer:
The circumcentre of the circle is (0.5,-0.5)
Step-by-step explanation:
Since this is a right triangle, UW is its diameter.
<u>CONCEPT :</u> The angle subtended by the diameter at the circumference of the circle =90°
Hence , center of circle is midpoint of line segment UW.
U(-3,2) and W(4,-3)
Taking the midpoint ,
C(
Center is C(0.5,-0.5) .
Radius = CV = 
R = 
Equation of circle is 
The circumcircle of triangle is (0.5,-0.5)
The function f(x)=4sin(2πx) is a sinusoidal function
The graph of the function f(x)=4sin(2πx) is graph (c)
<h3>How to determine the graph of the function f(x)=4sin(2πx)?</h3>
The parent function of a sine function is
f(x) = sin(x)
The function f(x)=4sin(2πx) implies that the parent function f(x) = sin(x) has been horizontally and vertically stretched
So, the graph of the function f(x)=4sin(2πx) would have a higher amplitude and shorter period than its parent function
Hence, the graph of the function f(x)=4sin(2πx) is graph (c)
