Answer: x = -12</h3>
=======================================================
Work Shown:
Let's label angle 2 as y, so y = x+132.
Also, let's add another variable z. We'll make z equal to the angle adjacent and supplementary to angle y. So y+z = 180
Solve for z to get
z = 180-y
z = 180-(x+132)
z = 180-x-132
z = 48-x
This angle z is added to the 90 degree angle to get the measure of the exterior angle 150 degrees. This is through the remote interior angle theorem.
So,
z+90 = 150
48-x+90 = 150
138-x = 150
-x = 150-138
-x = 12
x = -12
To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg.
<span>a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m. </span>
<span>b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2. </span>
<span>f = (ma), = .226 x 105.88, = 23.92N. </span>
Answer:
c
Step-by-step explanation:
In a multiple regression model X1 and X2 are two independent variables and the assumption is made that the effect of of X1 and X2 on dependent variables is independent of each other.For example let y be the student grade and x1 is the study hour and x2 be the IQ level of student so the multiple regression model for this scenario will be
Y=b0+b1x1+b2x2+e
Hence we can see that effect of study hour and IQ level on the student grade and the effect of study hour on the student grade is independent of the value of IQ level.
I dont see a problem here!!!!!!!!!
Answer:
Step-by-step explanation:
See the solution process below:
Explanation:
The slope-intercept form of a linear equation is: y =mx+b
Where m is the slope and b
is the y-intercept value.
We are given the slope in the problem so we can substitute
−5/6 for m in the formula.
And,
(0,6)
is the y-intercept so we can substitute
6
for
b
in the formula giving:
y
