Answer:
147.03 cm²
Step-by-step explanation:
Area of a parallelogram:
A = bh
A - area
b - base
h - height
From the figure,
Base = 16.9 cm
Height = 8.7 cm
A = (16.9)(8.7)
A = 147.03 cm²
Answer:
240
Step-by-step explanation:
The circuit's power is modeled by a quadratic function, whose graph is a parabola.
The maximum power is reached at the vertex.
So in order to find the maximum power, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into P(c).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.
Now let's take the zeros' average:
(0+8)/2=4.
The vertex's x-coordinate of this parabola is 4. Now let's find P(4).
P(4)=-15(4)(4-8)
240.
The maximum power of this circuit is 240 watts.
PLEASE MARK BRAINLIEST AND VERTIFIED ANSWER!! I spent a lot of time on this... :P thank you!!
Answer:
There is a strong negative relationship between x and y
Step-by-step explanation:
we know that
The correlation coefficient r measures the direction and strength of a linear relationship. It can take a range of values from +1 to -1.
Values between 0.7 and 1.0 (-0.7 and -1.0) indicate a strong positive (negative) linear relationship
In this problem
The correlation coefficient for the data is −0.9847
therefore
Is a strong negative correlation
Answer: -3(15m-4)/40
(All the numbers are above the fraction bar, then 40 is under the fraction bar)
