Answer: y=1.75
Step-by-step explanation:
STEP 1:
y=40-8.5x
Substitute x for 4.5.
y=40-38.25
STEP 2:
Simplify.
y=1.75
Hope this helps :)
Here we go ~
The general equation of ellipse is :
[ because it's a horizontal ellipse with centre at origin ]
so, let's equate given equation with the standard equation ~
se get :
As we know, length of minor axis is : 2b = 2 × 6 = 12 units
and, the smaller circle has diameter = 2b = 12 units
so, it's radius = 6 units ~
Now, let's write the equation of circle with origin as centre and radius = 6 units
[ h = 0, k = 0, since circle has centre at origin ]
Answer:
t=30
Step-by-step explanation:
Option B:
sin x = 1 is the equation represented by the intersection of the graph.
Solution:
The graph lies between -1 and 1 in y-axis.
x-axis of the graph is all real numbers.
The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.
That is the domain of the graph is all real numbers.
The range of the graph is [-1, 1].
It clearly shows that, it is the graph of sinx = 1.
Hence sin x = 1 is the equation represented by the intersection of the graph.
Option B is the correct answer.
Answer:
$2400
$12,400
Step-by-step explanation:
Simple interest equation:
PV(1+it)
we have
10000(1+.06*4)
10000(1.24)
12400
Subtract the PV to get the interest earned
12400-10000= 2400
We just found that the total would be 12,400 and so part B is already solved
